Market risk

BIPRU 7.1

Application, purpose, general provisions and non-standard transactions

  • 01/01/2007

Application

BIPRU 7.1.1

handbook-rule
This chapter applies to a BIPRU firm.
  • 01/01/2007

Purpose

BIPRU 7.1.2

handbook-guidance
The purpose of this chapter is to implement Annexes I, III, IV and V of the Capital Adequacy Directive.
  • 01/01/2007

General provisions: Obligation to calculate PRR

BIPRU 7.1.3

handbook-rule

A firm must calculate a PRR in respect of:

  1. (1) all its trading book positions;
  2. (2) all positions falling within BIPRU 7.5.3 R (Scope of the foreign exchange PRR calculation), whether or not in the trading book; and
  3. (3) all positions in commodities (including physical commodities) whether or not in the trading book;

even if no treatment is provided for that position in the other sections of this chapter.

  • 01/01/2007

BIPRU 7.1.4

handbook-rule

A firm must calculate a PRR for any position falling into BIPRU 7.1.3 R using:

  1. (1) the PRR calculations contained in BIPRU 7; or
  2. (2) another method provided the firm is able to demonstrate that in all circumstances the calculation being employed results in a higher PRR for the position than would be required under (1).
  • 01/01/2007

General provisions: Non-trading book items

BIPRU 7.1.5

handbook-guidance
Positions in instruments which are non-trading book items should be treated under BIPRU 3 (Standardised credit risk), BIPRU 4 (The IRB approach) or BIPRU 13 (Financial derivatives, SFTs and long settlement transactions) unless deducted as an illiquid asset. If they fall into BIPRU 7.1.3R(2) or (3) they also give rise to a PRR charge.
  • 01/11/2007

General provisions: Frequency of calculation

BIPRU 7.1.6

handbook-rule
A firm must be able to monitor its total PRR on an intra-day basis, and, before executing any trade, must be able to re-calculate PRR to the level of detail necessary to establish whether or not the firm's capital resources exceed its capital resources requirement.
  • 01/01/2007

BIPRU 7.1.7

handbook-guidance
A firm may rely on intra-day limits for the purposes of BIPRU 7.1.6R.
  • 01/01/2007

Purpose of rules for non-standard transactions and instruments for which no PRR treatment has been specified

BIPRU 7.1.8

handbook-guidance
The methodologies which have been developed for calculating PRR charges have been based on existing instruments and assume instruments with standard characteristics. However, as a result of innovation and because there are instruments which, although based on a standard contract, contain structural features which would make the rules in the rest of this chapter inappropriate, flexible rules are required. The rules in this section about transactions for which no PRR treatment has been specified and non-standard transactions are designed to address this.
  • 01/01/2007

Instruments for which no PRR treatment has been specified

BIPRU 7.1.9

handbook-rule
Where a firm has a position for which no PRR treatment has been specified, it must calculate the PRR for that position in accordance with BIPRU 7.1.12R-BIPRU 7.1.13R.
  • 01/01/2007

BIPRU 7.1.10

handbook-rule
If BIPRU 7.1.9 R applies, a firm must document its policies and procedures for calculating the PRR for that position of that type in its trading book policy statement.
  • 01/01/2007

BIPRU 7.1.11

handbook-guidance
Under BIPRU 1.2.30 R (2) a firm should notify the FSA as soon as is reasonably practicable if its trading book policy statement is subject to significant changes. Therefore if a firm makes a change in accordance with BIPRU 7.1.10R it should consider whether it is necessary to report it to the FSA.
  • 01/01/2007

BIPRU 7.1.12

handbook-rule
A firm may calculate the PRR for a position falling into BIPRU 7.1.9R by applying by analogy the rules relating to the calculation of the interest rate PRR, the equity PRR, the commodity PRR, the foreign currency PRR, the option PRR or the collective investment undertaking PRR if doing so is appropriate and if the position and PRR item are sufficiently similar to those that are covered by those rules.
  • 01/01/2007

BIPRU 7.1.13

handbook-rule
Where a firm has a position for which no PRR treatment has been specified and it is not applying BIPRU 7.1.12R, it must calculate a PRR of an appropriate percentage of the current value of the position calculated under GENPRU 1.3 (Valuation).
  • 01/01/2007

Instruments in non-standard form

BIPRU 7.1.14

handbook-rule
  1. (1) If a firm has a position:
    1. (a) in a PRR item in non-standard form; or
    2. (b) that is part of a non-standard arrangement; or
    3. (c) that, taken together with other positions (whether or not they are subject to PRR charges under BIPRU 7), gives rise to a non-standard market risk;
  2. the firm must notify the FSA of that fact and of details about the position, PRR item, arrangements and type of risk concerned.
  3. (2) Except as (1) provides to the contrary, (1) applies to a position that is subject to a PRR under BIPRU 7.1.3R.
  4. (3) The question of what is non-standard for the purposes of (1) must be judged by reference to the standards:
    1. (a) prevailing at the time the rule is being applied; and
    2. (b) of firms generally who carry on business which gives rise to PRRs under BIPRU 7 rather than merely by reference to the firm's own business.
  • 01/01/2007

BIPRU 7.1.15

handbook-rule
If a firm has a position or combination of positions falling into BIPRU 7.1.14R and the PRR relating to that position or positions materially underestimates the market risk incurred by the firm to which they give rise, the firm must calculate the PRR for that position or positions under BIPRU 7.1.13R.
  • 01/01/2007

Meaning of appropriate percentage for non-standard transactions

BIPRU 7.1.16

handbook-evidential-provisions
  1. (1) In BIPRU 7.1.13R and, to the extent that that rule applies BIPRU 7.1.13R, BIPRU 7.1.15R, an "appropriate percentage" is:
    1. (a) 100%; or
    2. (b) a percentage which takes account of the characteristics of the position concerned and of discussions with the FSA or a predecessor regulator under the Banking Act 1987 or the Financial Services Act 1986.
  2. (2) Compliance with (1) may be relied on as tending to establish compliance with BIPRU 7.1.13R or, insofar as it incorporates the requirements relating to an appropriate percentage, BIPRU 7.1.15R.
  3. (3) Contravention of (1) may be relied on as tending to establish contravention with BIPRU 7.1.13 R or, insofar as it incorporates the requirements relating to an appropriate percentage, BIPRU 7.1.15 R.
  • 01/01/2007

Stress testing and scenario analyses of trading book positions

BIPRU 7.1.17

handbook-rule
A firm must conduct a regular programme of stress testing and scenario analysis of its trading book positions, both at the trading desk level and on a firm-wide basis. The results of these tests must be reviewed by senior management and reflected in the policies and limits the firm sets.
  • 14/12/2009

BIPRU 7.1.17A

handbook-guidance
The firm's stress testing programme should be comprehensive in terms of both risk and firm coverage, and appropriate to the size and complexity of trading book positions held.
  • 14/12/2009

BIPRU 7.1.18

handbook-rule
In carrying out the stress tests and scenario analyses required by BIPRU 7.1.17 R, a firm must incorporate and take into account any other relevant stress tests and scenario analyses that it is required to carry out under any other provision of the Handbook, and in particular under BIPRU 7.10.72 R where the firm has a VaR model permission.
  • 14/12/2009

BIPRU 7.1.19

handbook-guidance

This paragraph gives guidance in relation to the stress testing programme that a firm must carry out in relation to its trading book positions.

  1. (1) The frequency of the stress testing of trading book positions should be determined by the nature of the positions.
  2. (2) The stress testing should include shocks which reflect the nature of the portfolio and the time it could take to hedge out or manage risks under severe market conditions.
  3. (3) The firm should have procedures in place to assess and respond to the results of the stress testing programme. In particular, stress testing should be used to evaluate the firm's capacity to absorb losses or to identify steps to be taken by the firm to reduce risk.
  4. (4) As part of its stress testing programme, the firm should consider how prudent valuation principles (see GENPRU 1.3) will be met in a stressed scenario.
  • 14/12/2009

BIPRU 7.1.20

handbook-guidance
The stress testing and scenario analysis under BIPRU 7.1.17 R should be taken into account under the overall Pillar 2 rule.
  • 14/12/2009

BIPRU 7.2

Interest rate PRR

  • 01/01/2007

General rule

BIPRU 7.2.1

handbook-rule
  1. (1) A firm must calculate its interest rate PRR under BIPRU 7.2 by:
    1. (a) identifying which positions must be included within the interest rate PRR calculation;
    2. (b) deriving the net position in each debt security in accordance with BIPRU 7.2.36R-BIPRU 7.2.41R;
    3. (c) including these net positions in the interest rate PRR calculation for general market risk and the interest rate PRR calculation for specific risk; and
    4. (d) summing all PRRs calculated for general market risk and specific risk.
  2. (2) A firm must calculate its interest rate PRR by adding the amount calculated under (1) to the amount calculated under the basic interest rate PRR calculation under BIPRU 7.3.45R.
  3. (3) All net positions, irrespective of their signs, must be converted on a daily basis into the firm's base currency at the prevailing spot exchange rate before their aggregation.
  4. (4) Net positions must be classified according to the currency in which they are denominated. A firm must calculate the capital requirement for general market risk and specific risk in each individual currency separately.
  • 01/01/2007

BIPRU 7.2.2

handbook-guidance
The interest rate PRR calculation divides the interest rate risk into the risk of loss from a general move in market interest rates, and the risk of loss from an individual debt security's price changing for reasons other than a general move in market interest rates. These are called general market risk and specific risk respectively.
  • 01/01/2007

Scope of the interest rate PRR calculation

BIPRU 7.2.3

handbook-rule

A firm's interest rate PRR calculation must:

  1. (1) include all trading book positions in debt securities, preference shares and convertibles, except:
    1. (a) positions in convertibles which have been included in the firm's equity PRR calculation;
    2. (b) positions fully deducted as a material holding under the calculations under the capital resources table, in which case the firm may exclude them; or
    3. (c) positions hedging an option which is being treated under BIPRU 7.6.26R (Table: Appropriate treatment for equities, debt securities or currencies hedging options);
  2. (2) include notional positions arising from trading book positions in the instruments listed in the table in BIPRU 7.2.4R; and
  3. (3) (if the firm is the transferor of debt securities or guaranteed rights relating to title to debt securities in a repurchase agreement or the lender of debt securities in a debt securities lending agreement) include such debt securities if those debt securities meet the criteria for inclusion in the trading book.
  • 01/01/2007

BIPRU 7.2.4

handbook-rule
Table: Instruments which result in notional positions
This table belongs to BIPRU 7.2.3R(2)
  • 01/01/2007

BIPRU 7.2.5

handbook-guidance
BIPRU 7.2.3R(1) includes a trading book position in debt security, preference share or convertible that is subsequently repo'd under a repurchase agreement or lent under a stock lending agreement. Clearly, if the security had initially been obtained via a reverse repurchase agreement or stock borrowing agreement, the security would not have been included in the PRR calculation in the first place.
  • 01/01/2007

BIPRU 7.2.6

handbook-guidance
  • 01/01/2007

BIPRU 7.2.7

handbook-guidance

Firms are reminded that the table in BIPRU 7.6.5R (Table: Appropriate PRR calculation for an option or warrant) divides options and warrants on interest rates, debt securities and interest rate futures and swaps into:

  1. (1) those which must be treated under BIPRU 7.6 (Option PRR); and
  2. (2) those which must be treated under either BIPRU 7.2 or BIPRU 7.6, the firm being able to choose whether BIPRU 7.2 or BIPRU 7.6 is used.
  • 01/01/2007

BIPRU 7.2.8

handbook-guidance
Cliquets on equities, baskets of equities or equity indices do not attract an interest rate PRR. The table in BIPRU 7.2.4R excludes them from the scope of the interest rate PRR calculation in BIPRU 7.2 and BIPRU 7.3.45R excludes them from the basic interest rate PRR calculation in BIPRU 7.3 (Equity PRR and basic interest rate PRR for equity derivatives).
  • 01/01/2007

BIPRU 7.2.9

handbook-guidance
The table in BIPRU 7.2.4R shows that equity derivatives are excluded from BIPRU 7.2's PRR calculation if they have been included in the basic interest rate PRR calculation in BIPRU 7.3 (see BIPRU 7.3.45R).
  • 01/01/2007

Derivation of notional positions: General approach

BIPRU 7.2.10

handbook-guidance

BIPRU 7.2.11 R - BIPRU 7.2.35R convert the instruments listed in the table in BIPRU 7.2.4R into notional positions in:

  1. (1) the underlying debt security, where the instrument depends on the price (or yield) of a specific debt security; or
  2. (2) notional debt securities to capture the pure interest rate risk arising from future payments and receipts of cash (including notional payments and receipts) which, because they are designed to represent pure general market risk (and not specific risk), are called zero-specific-risk securities; or
  3. (3) both (1) and (2).
  • 01/01/2007

BIPRU 7.2.11

handbook-rule
  1. (1) For the purposes of calculating interest rate PRR, unless specified otherwise, a firm must derive the value of notional positions as follows:
    1. (a) notional positions in actual debt securities must be valued as the nominal amount underlying the contract at the current market price of the debt security; and
    2. (b) positions in zero-specific-risk securities must be valued using one of the two methods in (2).
  2. (2) A firm must use one of the following two methods for all positions arising under (1)(b) and must use the same method for all positions denominated in the same currency:
    1. (a) the present value approach, under which the zero-specific-risk security is assigned a value equal to the present value of all the future cash flows that it represents; or
    2. (b) the alternative approach, under which the zero-specific-risk security is assigned a value equal to:
      1. (i) the market value of the underlying notional equity position in the case of an equity derivative;
      2. (ii) the notional principal amount in the case of an interest rate or foreign currency swap; or
      3. (iii) the notional amount of the future cash flow that it represents in the case of any other CRD financial instrument.
  • 01/01/2007

BIPRU 7.2.12

handbook-rule
A firm must use BIPRU 7.2.11R(2)(a) in respect of any positions that it includes in the interest rate duration method.
  • 01/01/2007

Derivation of notional positions: Futures, forwards or synthetic futures on a debt security

BIPRU 7.2.13

handbook-rule

Futures, forwards or synthetic futures on a single debt security must be treated as follows:

  1. (1) a purchased future, synthetic future or forward is treated as:
    1. (a) a notional long position in the underlying debt security (or the cheapest to deliver (taking into account the conversion factor) where the contract can be satisfied by delivery of one from a range of securities); and
    2. (b) a notional short position in a zero coupon zero-specific-risk security with a maturity equal to the expiry date of the future or forward; and
  2. (2) a sold future, synthetic future or forward is treated as:
    1. (a) a notional short position in the underlying security (or the cheapest to deliver (taking into account the conversion factor) where the contract can be satisfied by delivery of one from a range of securities); and
    2. (b) a notional long position in a zero coupon zero-specific-risk security with a maturity equal to the expiry date of the future, synthetic future or forward.
  • 01/01/2007

Derivation of notional positions: Futures, forwards or synthetic futures on a basket or index of debt securities

BIPRU 7.2.14

handbook-rule

Futures, forwards or synthetic futures on a basket or index of debt securities must be converted into forwards on single debt securities as follows (and then the resulting positions must be treated under BIPRU 7.2.13R):

  1. (1) futures, synthetic futures or forwards on a single currency basket or index of debt securities must be treated as either:
    1. (a) a series of forwards, one for each of the constituent debt securities in the basket or index, of an amount which is a proportionate part of the total underlying the contract according to the weighting of the relevant debt security in the basket; or
    2. (b) a single forward on a notional debt security; and
  2. (2) futures, synthetic futures or forwards on multiple currency baskets or indices of debt securities must be treated as either:
    1. (a) a series of forwards (using the method described in (1)(a)); or
    2. (b) a series of forwards, each one on a notional debt security to represent one of the currencies in the basket or index, of an amount which is a proportionate part of the total underlying the contract according to the weighting of the relevant currency in the basket.
  • 01/01/2007

BIPRU 7.2.15

handbook-guidance
Under BIPRU 7.2.14R(2)(b), a forward on basket of three Euro denominated debt securities and two Dollar denominated debt securities would be treated as a forward on a single notional Euro denominated debt security and a forward on a single notional Dollar denominated debt security.
  • 01/01/2007

BIPRU 7.2.16

handbook-rule
The notional debt securities in BIPRU 7.2.14R are assigned a specific risk PRA and a general market risk PRA equal to the highest that would apply to the debt securities in the basket or index.
  • 01/01/2007

BIPRU 7.2.17

handbook-guidance
The debt security with the highest specific risk PRA within the basket might not be the same as the one with the highest general market risk PRA . BIPRU 7.2.16R requires a firm to select the highest percentages even where they relate to different debt securities in the basket or index, and regardless of the proportion of those debt securities in the basket or index.
  • 01/01/2007

Derivation of notional positions: Interest rate futures and forward rate agreements (FRAs)

BIPRU 7.2.18

handbook-rule
Interest rate futures or FRAs must be treated as the two notional positions (one long, one short) shown in the table in BIPRU 7.2.19R.
  • 01/01/2007

BIPRU 7.2.19

handbook-rule
Table: Interest rate futures and FRAs
This table belongs to BIPRU 7.2.18R
  • 01/01/2007

BIPRU 7.2.20

handbook-guidance
  1. (1) The following example illustrates BIPRU 7.2.18R and BIPRU 7.2.19R in conjunction with BIPRU 7.2.11R (the last rule determines the value of notional positions). A firm sells £1mn notional of a 3v6 FRA at 6%. This results in:
    1. (a) a short position in a zero-specific-risk security with a zero coupon, three month maturity, and a nominal amount of £1million; and
    2. (b) a long position in a zero-specific-risk security with a zero coupon, six month maturity, and nominal amount of £1,015,000 (i.e. notional plus interest at 6% over 90 days).
  2. (2) If a firm were to apply the approach in BIPRU 7.2.11R(2)(a) the two nominal amounts would have to be present valued.
  • 01/01/2007

Derivation of notional positions: Interest rate swaps or foreign currency swaps

BIPRU 7.2.21

handbook-rule
Interest rate swaps or foreign currency swaps without deferred starts must be treated as the two notional positions (one long, one short) shown in the table in BIPRU 7.2.22R.
  • 01/01/2007

BIPRU 7.2.22

handbook-rule
Table: Interest rate and foreign currency swaps
This table belongs to BIPRU 7.2.21R
  • 01/01/2007

BIPRU 7.2.23

handbook-guidance
For a foreign currency swap, the two notional zero-specific-risk securities would be denominated in different currencies. A foreign currency swap is also included in the foreign currency PRR calculation.
  • 01/01/2007

Derivation of notional positions: Deferred start interest rate swaps or foreign currency swaps

BIPRU 7.2.24

handbook-rule
Interest rate swaps or foreign currency swaps with a deferred start must be treated as the two notional positions (one long, one short) shown in the table in BIPRU 7.2.25R.
  • 01/01/2007

This table belongs to BIPRU 7.2.24R
  • 01/01/2007

BIPRU 7.2.26

handbook-guidance
An example of BIPRU 7.2.24R is as follows. A firm enters into a five year swap which starts in two year's time. The firm has contracted to receive 6% and pay six month Libor on a principal amount of £1 million. This results in a long position in a 7 year debt security and a short position in a 2 year debt security. Both have a coupon of 6%. BIPRU 7.2.24R deals with the capital treatment of the delayed start date; once the swap has started, BIPRU 7.2.21R applies.
  • 01/01/2007

Derivation of notional positions: Swaps where only one leg is an interest rate leg (e.g. equity swaps)

BIPRU 7.2.27

handbook-rule

A firm must treat a swap with only one interest rate leg as a notional position in a zero-specific-risk security:

  1. (1) with a coupon equal to that on the interest rate leg;
  2. (2) with a maturity equal to the date that the interest rate will be reset; and
  3. (3) which is a long position if the firm is receiving interest payments and short if making interest payments.
  • 01/01/2007

BIPRU 7.2.28

handbook-guidance
BIPRU 7.2.27R includes equity swaps, commodity swaps and any other swap where only one leg is an interest rate leg.
  • 01/01/2007

Derivation of notional positions: Cash legs of repurchase agreements and reverse repurchase agreements

BIPRU 7.2.29

handbook-guidance
Firms are reminded that for the purposes of BIPRU 7.2.30R, a repurchase agreement includes a sell/buy back or stock lending; and a reverse repurchase agreement includes a buy/sell back or a stock borrowing.
  • 01/01/2007

BIPRU 7.2.30

handbook-rule

The forward cash leg of a repurchase agreement or reverse repurchase agreement must be treated as a notional position in a zero-specific-risk security which:

  1. (1) is a short notional position in the case of a repurchase agreement; and a long notional position in the case of a reverse repurchase agreement;
  2. (2) has a value equal to the market value of the cash leg;
  3. (3) has a maturity equal to that of the repurchase agreement or reverse repurchase agreement; and
  4. (4) has a coupon equal to:
    1. (a) zero, if the next interest payment date coincides with the maturity date; or
    2. (b) the interest rate on the contract, if any interest is due to be paid before the maturity date.
  • 01/01/2007

Derivation of notional positions: Cash borrowings and deposits

BIPRU 7.2.31

handbook-rule

A cash borrowing or deposit must be treated as a notional position in a zero coupon zero-specific-risk security which:

  1. (1) is a short position in the case of a borrowing and a long position in the case of a deposit;
  2. (2) has a value equal to the market value of the borrowing or deposit;
  3. (3) has a maturity equal to that of the borrowing or deposit, or the next date the interest rate is reset (if earlier); and
  4. (4) has a coupon equal to:
    1. (a) zero, if the next interest payment date coincides with the maturity date; or
    2. (b) the interest rate on the borrowing or deposit, if any interest is due to be paid before the maturity date.
  • 01/01/2007

Derivation of notional positions: Options and warrants

BIPRU 7.2.32

handbook-rule
  1. (1) Where included in the PRR calculation in BIPRU 7.2 (see the table in BIPRU 7.2.4R), options and warrants must be treated in accordance with this rule.
  2. (2) An option or warrant on a debt security, a basket of debt securities or a debt security index must be treated as a position in that debt security, basket or index.
  3. (3) An option on an interest rate must be treated as a position in a zero coupon zero-specific-risk security with a maturity equal to the sum of the time to expiry of the option and the length of the period for which the interest rate is fixed.
  4. (4) An option on a future - where the future is based on an interest rate or debt security - must be treated as:
    1. (a) a long position in that future for purchased call options and written put options; and
    2. (b) a short position in that future for purchased put options and written call options.
  5. (5) An option on a swap must be treated as a deferred starting swap.
  • 01/01/2007

Derivation of notional positions: Bonds where the coupons and principal are paid in different currencies

BIPRU 7.2.33

handbook-rule

Where a debt security pays coupons in one currency, but will be redeemed in a different currency, it must be treated as:

  1. (1) a debt security denominated in the coupon's currency; and
  2. (2) a foreign currency forward to capture the fact that the debt security's principal will be repaid in a different currency from that in which it pays coupons, specifically:
    1. (a) a notional forward sale of the coupon currency and purchase of the redemption currency, in the case of a long position in the debt security; or
    2. (b) a notional forward purchase of the coupon currency and sale of the redemption currency, in the case of a short position in the debt security.
  • 01/01/2007

Derivation of notional positions: Interest rate risk on other futures, forwards and options

BIPRU 7.2.34

handbook-rule

Other futures, forwards, options and swaps treated under BIPRU 7.2 must be treated as positions in zero-specific-risk securities, each of which:

  1. (1) has a zero coupon;
  2. (2) has a maturity equal to that of the relevant contract; and
  3. (3) is long or short according to the table in BIPRU 7.2.35R.

Deriving the net position in each debt security: General

BIPRU 7.2.36

handbook-rule
The net position in a debt security is the difference between the value of the firm's long positions (including notional positions) and the value of its short positions (including notional positions) in the same debt security.

Definition of a qualifying debt security

BIPRU 7.2.49

handbook-rule

A debt security is a qualifying debt security if:

  1. (1) it qualifies for a credit quality step under the standardised approach to credit risk corresponding at least to investment grade; or
  2. (2) it has a PD which, because of the solvency of the issuer, is not higher than that of the debt securities referred to under (1) under the IRB approach; or
  3. (3) it is a debt security for which a credit assessment by a nominated ECAI is unavailable and which meets the following conditions:
    1. (a) it is considered by the firm to be sufficiently liquid;
    2. (b) it is of investment quality, according to the firm's own discretion, at least equivalent to that of the debt securities referred to under (1); and
    3. (c) it is listed on at least one regulated market or designated investment exchange; or
  4. (4) it is a debt security issued by an institution subject to the capital adequacy requirements set out in the Banking Consolidation Directive that satisfies the following conditions:
    1. (a) it is considered by the firm to be sufficiently liquid;
    2. (b) its investment quality is, according to the firm's own discretion, at least equivalent to that of the assets referred to under (1) above; or
  5. (5) it is a debt security issued by an institution that is deemed to be of equivalent or higher credit quality than that associated with credit quality step 2 under the standardised approach to credit risk and that is subject to supervision and regulatory arrangements comparable to those under the Capital Adequacy Directive.
  • 01/01/2007

General market risk calculation: Simplified maturity method

BIPRU 7.2.55

The interest rate simplified maturity method weights individual net positions to reflect their price sensitivity to changes in interest rates. The weights are related to the coupon and the residual maturity of the instrument (or the next interest rate re-fix date for floating rate items).
  • 01/01/2007

BIPRU 7.2.56

handbook-rule
Under the interest rate simplified maturity method, the portion of the interest rate PRR for general market risk equals the sum of each individual net position (long or short) multiplied by the appropriate PRA in the table in BIPRU 7.2.57R. A firm must assign its net positions to the appropriate maturity bands in the table in BIPRU 7.2.57R on the basis of residual maturity in the case of fixed-rate instruments and on the basis of the period until the interest rate is next set in the case of instruments on which the interest rate is variable before final maturity.

Under the interest rate maturity method, the portion of the interest rate PRR for general market risk is calculated as follows:

  1. (1) Step 1: each net position is allocated to the appropriate maturity band in the table in BIPRU 7.2.57R and multiplied by the corresponding PRA;
  2. (2) Step 2: weighted long and short positions are matched within:
    1. (a) the same maturity band;
    2. (b) the same zone (using unmatched positions from (a)); and
    3. (c) different zones (using unmatched positions from (b) and matching between zones 1 and 2 and 2 and 3 before zone 1 and 3); and
  3. (3) Step 3: the portion of the interest rate PRR for general market risk is the sum of:
    1. (a) 10% of the total amount matched within maturity bands;
    2. (b) 40% of the amount matched within zone 1 under (2)(b);
    3. (c) 30% of the amount matched within zones 2 & 3 under (2)(b);
    4. (d) 40% of the amounts matched between zones 1 and 2, and between zones 2 and 3;
    5. (e) 150% of the amount matched between zones 1 and 3; and
    6. (f) 100% of the weighted positions remaining unmatched after (2)(c).
  • 01/01/2007

BIPRU 7.2.60

handbook-guidance
The table in BIPRU 7.2.57R distinguishes between debt securities with a coupon of less than 3% and those with coupon in excess of 3%. However, this does not mean that the firm has to do a separate general market risk calculation for each; it merely ensures that when allocating debt securities to a particular band, their coupons are taken into account as well as their maturities. So for example, a 21 year 6% debt security falls into the same band as an 11 year 2% debt security. They are both weighted at 6%, and can be matched under BIPRU 7.2.59R(2)(a) (the first part of step two of the interest rate maturity method calculation) because they fall within the same band.

  1. (1) A firm must use the following formula to calculate modified duration for the purpose of the interest rate duration method:
  3. (2)
  5. (3) For the purpose of the formulae in (1) and (2):
    1. (a) Ct=cash payment at time t
    2. (b) m=total maturity
    3. (c) r=yield to maturity. In the case of a fixed-rate debt security a firm must take the current mark to market of the debt security and thence calculate its yield to maturity, which is the implied discount rate for that instrument. In the case of a floating rate instrument, a firm must take the current mark to market of the debt security and thence calculate its yield on the assumption that the principal is due on the date that the interest rate can next be changed.
    4. (d) t=time
  • 01/01/2007

BIPRU 7.2.64

handbook-rule

Under the interest rate duration method, the portion of the interest rate PRR for general market risk is calculated as follows:

  1. (1) Step 1: allocate each net position to the appropriate duration zone in the table in BIPRU 7.2.65R and multiply it by:
    1. (a) its modified duration (using the formula in BIPRU 7.2.63R); and
    2. (b) the appropriate assumed interest rate change in the table in BIPRU 7.2.65R;
  2. (2) Step 2: match weighted long and short positions:
    1. (a) within zones; and
    2. (b) across zones (using unmatched positions from (2)(a) and following the process in BIPRU 7.2.59R (2)(c)); and
  3. (3) Step 3: calculate the portion of the interest rate PRR for general market risk as the sum of:
    1. (a) 100% of the weighted positions remaining unmatched after (2)(b);
    2. (b) 2% of the matched weighted position in each zone;
    3. (c) 40% of the matched weighted position between zones 1 and 2, and between zones 2 and 3; and

Standard equity method

BIPRU 7.3.31

handbook-guidance
The standard equity method divides the risk of loss from a firm's equity positions into the risk of loss from a general move in a country's equity market and the risk of loss from an individual equity's price changing relative to that country's equity market. These are called general market risk and specific risk respectively.
  • 01/01/2007

BIPRU 7.3.32

handbook-rule

Under the standard equity method, a firm must:

  1. (1) group equity positions into country portfolios as follows:
    1. (a) a position in an individual equity belongs to:
      1. (i) the country it is listed in;
      2. (ii) any of the countries it is listed in, if more than one; or
      3. (iii) the country it was issued from, if unlisted;
    2. (b) a position in an equity basket or index that is treated under BIPRU 7.3.15R(2), is allocated to one or more country portfolios based on the countries to which the underlying equities belong to under (a) or a notional country provided for in the table in BIPRU 7.3.16R; and
  2. (2) sum:
    1. (a) the PRRs for specific risk calculated under BIPRU 7.3.33R; and

Definition of a qualifying equity

BIPRU 7.3.35

handbook-rule

A qualifying equity is one that satisfies the following conditions:

  1. (1) it belongs to a country portfolio that satisfies the following conditions:
    1. (a) no individual position exceeds 10% of the portfolio's gross value; and
    2. (b) the sum of positions (ignoring the sign) which individually represent between 5% and 10% of the portfolio's gross value, does not exceed 50% of the portfolio's gross value;
  2. (2) it is not of an issuer that has issued only traded debt securities that currently attracts an 8% or 12% PRA in the table in BIPRU 7.2.44R (Specific risk PRA) or that attract a lower requirement only because they are guaranteed or secured; and
  3. (3) it is a constituent of an index in the table in BIPRU 7.3.39R.

  1. (1) The following example illustrates BIPRU 7.3.35R(1).
  2. (2) A country portfolio has a gross value of £100 and is made up of positions in 29 different equities (some are long positions, others are short positions). Not all the equities are constituents of an index used to create the FT All-World Index (this criterion only becomes relevant once a firm has determined whether the country portfolio meets the test in BIPRU 7.3.35R(1)).
  3. (3) Six positions exceed the 5% threshold. The following diagram shows the composition of the portfolio.
  5. (4) Part (a): the portfolio meets the first part of the test because no individual position is worth more than 10% of the portfolio's value.
  6. (5) Part (b): the portfolio fails the second part of the test because the sum (ignoring the sign) of the six relevant positions is £52; this exceeds 50% of the portfolio's value.

  2. (2) Continuing the example above, one of the largest positions is taken out of the portfolio and put into a new portfolio. The new portfolio fails the two tests, but the amended portfolio meets both tests:
    1. (a) Part (a): no single remaining position exceeds £9.10.
    2. (b) Part (b): the sum of the five relevant positions is £43, this is less than 50% of the new portfolio's value of £91.

A basic interest rate PRR calculation is included in BIPRU 7.3 for a firm that does not wish to use the calculation in BIPRU 7.2 (Interest rate PRR). However, it tends to result in higher charges than the methods in BIPRU 7.2, largely because the interest rate PRR is calculated on each notional equity position separately and then summed without offsetting long and short positions.

However it does not apply to cliquet as defined in BIPRU 7.6.18R (Table: Option PRR: methods for different types of option). A firm must calculate the interest rate PRR for a position being treated under this rule as follows:

Where a forward, future, CFD, synthetic future or option (unless already included in the firm's option PRR calculation) settles according to:

  1. (1) the difference between the price set on trade date and that prevailing at contract expiry, the notional position:
    1. (a) equals the total quantity underlying the contract; and
    2. (b) has a maturity equal to the expiry date of the contract; and
  2. (2) the difference between the price set on trade date and the average of prices prevailing over a certain period up to contract expiry, there is a notional position for each of the reference dates used in the averaging period to calculate the average price, which:
    1. (a) equals a fractional share of the total quantity underlying the contract; and
    2. (b) has a maturity equal to the relevant reference date.

    1. (a) equal 5 tonnes per day (1/20 of 100 tonnes); and
    2. (b) have a maturity equal to one of the business days in June (one for each day).
  3. (3) In this example as each business day in June goes by the quantity per day for the remaining days does not change (5 tonnes per day) only the days remaining changes. Therefore, halfway through June there are ten, 5 tonne short notional positions remaining each for the ten remaining business days in June.

Commitments to buy or sell at the average spot price of the commodity prevailing over some period between trade date and maturity must be treated as a combination of:

  1. (1) a position equal to the full amount underlying the contract with a maturity equal to the maturity date of the contract which is:
    1. (a) long, where the firm will buy at the average price; or
    2. (b) short, where the firm will sell at the average price; and
  2. (2) a series of notional positions, one for each of the reference dates where the contract price remains unfixed, each of which:
    1. (a) is long if the position under (1) is short, or short if the position under (1) is long;
    2. (b) equals a fractional share of the total quantity underlying the contract; and
    3. (c) has a maturity date of the relevant reference date.

The following guidance provides an example of BIPRU 7.4.10R. In January, a firm agrees to buy 100 tonnes of copper for the average spot price prevailing during the 20 business days in February, and will settle on 30 June. After entering into this agreement, the firm faces the risk that the average price for February increases relative to that for 30 June. Therefore, as highlighted in the table below:

  1. (1) the short positions reflect the fact that this could occur because any one of the remaining forward prices for February increase; and
  2. (2) the long position reflects the fact that this loss could occur because the forward price for 30 June falls.

    1. (a) treated as a single notional commodity position (separate from all other commodities); or
    2. (b) divided into notional positions, one for each of the constituent commodities in the index, of an amount which is a proportionate part of the total underlying the contract according to the weighting of the relevant commodity in the index;
  2. (2) Step 2: each notional position determined in Step 1 must then be included:
    1. (a) when using the commodity simplified approach (BIPRU 7.4.24R), without adjustment; or
    2. (b) when using the commodity maturity ladder approach (BIPRU 7.4.25R) or the commodity extended maturity ladder approach (BIPRU 7.4.32R), with the adjustments in BIPRU 7.4.14R.

  1. (1) An example of using BIPRU 7.4.13R and the table in BIPRU 7.4.14R is as follows.
  2. (2) A firm is long a three-month commodity index future where the spot level of the index is based on the one, two and three month forward prices of aluminium, copper, tin, lead, zinc and nickel (18 prices in total).
  3. (3) Step 1: the firm should decide whether to treat the full quantity underlying the contract as a single notional commodity position or disaggregate it into notional positions in aluminium, copper, tin, lead, zinc and nickel. In this case the firm decides to disaggregate the contract into notional positions in aluminium, copper, tin, lead, zinc and nickel.
  4. (4) Step 2: if the firm uses the commodity simplified approach, nothing more need be done to arrive at the notional position. In this case the firm uses the commodity maturity ladder approach and so subdivides each position in each metal into three because the level of the index is based on the prevailing one, two and three month forward prices. Since the future will be settled in three months' time at the prevailing level of the index, the three positions for each metal will have maturities of four, five and six months respectively.

    2. (b) (in the case of positions arising under contracts traded in markets with daily delivery dates) within 10 business days of each other.
  3. (3) Step 2: allocate the positions remaining after step 1 to the appropriate maturity band in the table in BIPRU 7.4.28R (physical commodity positions are allocated to band 1).
  4. (4) Step 3: match long and short positions within each band. In each instance, calculate a spread charge equal to the matched amount multiplied first by the spot price for the commodity and then by the spread rate of 3%.
  5. (5) Step 4: carry unmatched positions remaining after step 3 to another band where they can be matched, then match them. Do this until all matching possibilities are exhausted. In each instance, calculate:
    1. (a) a carry charge equal to the carried position multiplied by the spot price for the commodity, the carry rate of 0.6% and the number of bands by which the position is carried; and
    2. (b) a spread charge equal to the matched amount multiplied by the spot price for the commodity and the spread rate of 3%.
  6. (6) Step 5: calculate the outright charge on the remaining positions (which will either be all long positions or all short positions). The outright charge equals the remaining position (ignoring the sign) multiplied by the spot price for the commodity and the outright rate of 15%.

BIPRU 7.4.34

For the purposes of BIPRU 7.4.31R(1) a firm has a diversified commodity portfolio where it holds positions in more than one commodity in each of the categories set out in the table in BIPRU 7.4.33R and holds positions across different maturities in those individual commodities. A firm would not have a diversified commodity portfolio if it held positions in only one commodity in each of the categories set out in the table in BIPRU 7.4.33R. This is because the rates in the table in BIPRU 7.4.33R assume firms have positions in more than one of that category's commodities. Different commodities within a given category are likely to exhibit different volatilities, so where a firm does not have a diversified commodity portfolio in that category, the rates applying to that category might underestimate the regulatory capital required for a certain commodity at certain times.

What constitutes significant business in BIPRU 7.4.31R(2) will vary from firm to firm. The more regularly the firm undertakes trades in commodities and the more consistently it has positions in the relevant commodity, the more likely it is to be undertaking significant business for the purposes of BIPRU 7.4.31R(2).

Where a firm is:

  1. (1) treating a commodity index derivative as if it was based on a single separate commodity (see BIPRU 7.4.13R(1)(a)); and
  2. (2) using the commodity extended maturity ladder approach to calculate the commodity PRR for that commodity;

it must determine which index constituent incurs the highest rate in the table in BIPRU 7.4.33R and apply that rate to the notional position for the purposes of BIPRU 7.4.32R.

Where an index is only based on precious metals, BIPRU 7.4.13R and BIPRU 7.4.36R allow the firm to treat the single notional position as precious metal for the purposes of BIPRU 7.4.32R. However, if the index contained a mix of precious metals and base metals the firm would have to treat the notional position under BIPRU 7.4.36R as a base metal because base metals attract a higher rate than precious metals in the table in BIPRU 7.4.33R.

  3. (3) A firm may rely on third party reporting of the foreign currency positions in the CIU, where the correctness of this report is adequately ensured.
  4. (4) If a firm is not aware of the foreign currency positions in a CIU, the firm must assume that the CIU is invested up to the maximum extent allowed under the CIUs mandate in foreign currency and the firm must, for trading book positions, take account of the maximum indirect exposure that it could achieve by taking leveraged positions through the CIU when calculating its foreign currency PRR. This must be done by proportionally increasing the position in the CIU up to the maximum exposure to the underlying investment items resulting from the investment mandate.
  5. (5) The assumed position of the CIU in foreign currency calculated in accordance with BIPRU 7.5.18R(4) must be treated as a separate currency according to the treatment of investments in gold, subject to the modification that, if the direction of the CIUs investment is available, the total long position may be added to the total long open foreign currency position and the total short position may be added to the total short open foreign currency position.

handbook-rule

The option PRR for a written cliquet option is the market value of the derived position (see BIPRU 7.6.9R) multiplied by the appropriate PRA (see BIPRU 7.6.8R) multiplied by F+1 (see the following provisions of this paragraph). This result may be reduced by the amount the option is out of the money (subject to a maximum reduction to zero). The option PRR for a written cliquet option is therefore defined by the following formula:
[ PRA * underlying * (F + 1)] - OTM
where:

  1. (1)
  3. (2) FR= Number of forward re-sets
  4. (3) Y= Years to maturity
  5. (4) OTM= the amount by which the option is out of the money

Interaction with other chapters

BIPRU 7.6.32

handbook-guidance
The application of an option PRR to a position does not prevent any of the other PRR charges from applying if they would otherwise do so. In particular if a firm applies an option PRR to an equity derivative an interest rate PRR will also generally apply.

BIPRU 7.6.35

handbook-rule

For the purpose of identifying the appropriate treatment for the purpose of BIPRU 7.6.5R, the underlying position for the purpose of BIPRU 7.6.8R and the derived position under BIPRU 7.6.13R a firm may choose between treating an option on a CIU as being:

  1. (1) a position in the CIU itself; or
  2. (2) (if the conditions in BIPRU 7.7 (Position risk requirements for collective investment undertakings) for the use of the method in question are satisfied) positions in the underlying investments or assumed positions arising through the use of the standard CIU look through method or the modified CIU look through method.
  • 01/01/2007

BIPRU 7.6.36

handbook-guidance
  1. (1) This paragraph gives an example of how the appropriate PRA should be calculated for the purpose of deciding whether or not an option on a CIU is sufficiently in the money for the firm to have a choice whether or not to apply an option PRR. This example assumes that there is no leveraging (see BIPRU 7.7.11R (CIU modified look through method)).
  2. (2) Say that the CIU contains underlying equity position and the firm is using one of the CIU look through methods. The appropriate PRA for some is 8% and for the others is 12%. The firm should identify the highest appropriate PRA for the underlyings. In this case it is 12%. Therefore in this case the option would need to be in the money by more than 12% in order for the firm to have a choice between applying the option PRR or one of the other PRR charges.
  3. (3) However if the firm is not using one of the CIU look through methods the option would need to be in the money by more than 32% in order for the firm to have a choice between applying the option PRR or the CIU PRR.

Risk management

BIPRU 7.8.38

handbook-rule
A firm must take reasonable steps to establish and maintain such systems and controls to monitor and manage its underwriting and sub-underwriting business as are appropriate to the nature, scale and complexity of its underwriting and sub-underwriting business. In particular, a firm must have systems to monitor and control its underwriting exposures between the time of the initial commitment and working day one in the light of the nature of the risks incurred in the markets in question.
  • 01/01/2007

BIPRU 7.8.39

handbook-guidance

A firm should take reasonable steps to:

  1. (1) allocate responsibility for the management of its underwriting and sub-underwriting business;
  2. (2) allocate adequate resources to monitor and control its underwriting and sub-underwriting business;
  3. (3) satisfy itself that its systems to monitor exposure to counterparties will calculate, revise and update its exposure to each counterparty arising from its underwriting or sub-underwriting business;
  4. (4) satisfy itself of the suitability of each person who performs functions for it in connection with the firm's underwriting and sub-underwriting business having regard to the person's skill and experience; and
  5. (5) satisfy itself that its procedures and controls to monitor and manage its underwriting business address, on an on-going basis, the capacity of sub-underwriters to meet sub-underwriting commitments.

BIPRU 7.9

Use of a CAD 1 model

  • 01/01/2007

Introduction

BIPRU 7.9.1

handbook-guidance
A firm is required under GENPRU 2.1.52 R (Calculation of the market risk capital requirement) to calculate its market risk capital requirement using the rules in BIPRU 7. However, the FSA may at the firm's request modify GENPRU 2.1.52 R to allow the firm to calculate all or part of the PRR for the positions covered by that model by using a CAD 1 model (for options risk aggregation and/or interest rate pre-processing) or a VaR model (value at risk model) instead. BIPRU 7.10 (Use of a Value at Risk Model) deals with VaR model permissions.
  • 01/01/2007

BIPRU 7.9.2

handbook-guidance

The purpose of BIPRU 7.9 is to provide guidance on the FSA's policy for granting CAD 1 model waivers under section 148 of the Act (Modification or waiver of rules). The policy recognises that CAD 1 models may vary across firms but, as a minimum, the FSA will need to be satisfied:

  1. (1) about the quality of the internal controls and risk management relating to the model (see BIPRU 7.9.19G - BIPRU 7.9.23G for further details);
  2. (2) about the quality of the model standards; and
  3. (3) that the CAD 1 model captures and produces an accurate measure of the risks inherent in the portfolio covered by the CAD 1 model (see BIPRU 7.9.25G - BIPRU 7.9.53G for further details).
  • 01/01/2007

BIPRU 7.9.3

handbook-guidance
BIPRU 7.9 also explains how the output from the CAD 1 model is fed into the market risk capital requirement calculation.
  • 01/01/2007

BIPRU 7.9.4

handbook-guidance
If a CAD 1 model waiver is granted by the FSA, the waiver will contain certain requirements. In order adequately to address individual circumstances, these may differ from what is set out in BIPRU 7.9. The waiver will also identify the rules to which the waiver applies and the scope of model recognition granted to the firm.
  • 01/01/2007

BIPRU 7.9.5

handbook-guidance
Waivers permitting the use of models in the calculation of PRR will not be granted if that would be contrary to the CAD. Any waiver which is granted will only be granted on terms that are compatible with the CAD. Accordingly, the only waivers permitting the use of models in calculating PRR that the FSA is likely to grant are CAD 1 model waivers and VaR model permissions.
  • 01/01/2007

Scope of CAD 1 models

BIPRU 7.9.6

handbook-guidance
The FSA recognises two types of CAD 1 model. The table in BIPRU 7.9.7G describes them.

BIPRU 7.9.8

handbook-guidance

Currently the FSA only envisages allowing recognition for options on CIUs if the CIU satisfies one of the following conditions:

  1. (1) it is a regulated collective investment scheme; or
  2. (2) the firm can demonstrate that it has characteristics that are similar to or better than an undertaking in (1) from the point of view of transparency and liquidity.
  • 01/01/2007

The CAD 1 model waiver application and review process

BIPRU 7.9.9

handbook-guidance
Details of the general waiver process are set out in SUP 8 (Waiver and modification of rules). Further details of the waiver process applicable to certain waivers relating to BIPRU (including CAD 1 model waivers) can be found in BIPRU 1.3 (Applications for advanced approaches). Because of the complexity of a CAD 1 model waiver, it is recommended that, as set out in SUP 8.3.4 G and BIPRU 1.3.21 G, a firm contact its usual contact at the FSA to discuss its proposed application. It should also be noted that the waiver recognition process in the case of a CAD 1 model may take longer than the timescales indicated in SUP 8.3.5 G.
  • 01/01/2007

BIPRU 7.9.10

handbook-guidance
In order to consider a CAD 1 model waiver request, the FSA may undertake a review to ensure that it is adequate and appropriate for the PRR calculation.
  • 01/01/2007

BIPRU 7.9.11

handbook-guidance
The model review process may be conducted through a series of visits covering various aspects of the firm's control and IT environment. Before these visits the FSA may ask the firm to provide some information relating to its waiver request accompanied by some specified background material. The model review visits are organised on a timetable that allows a firm being visited sufficient time to arrange the visit and provide the appropriate pre-visit information.
  • 01/01/2007

BIPRU 7.9.12

handbook-guidance
As part of the model review process, the following may be reviewed: organisational structure and personnel; details of the firm's market position in the relevant products; profit and risk information; valuation and reserving policies; operational controls; IT systems; model release and control procedures; risk management and control framework; risk appetite and limit structure and future developments relevant to model recognition.
  • 01/01/2007

BIPRU 7.9.13

handbook-guidance
The FSA will normally require meetings with senior management and staff from the front office, financial control, risk management, operations, systems development, information technology and audit areas.
  • 01/01/2007

BIPRU 7.9.14

handbook-guidance
A review by a skilled person may be used before a CAD 1 model waiver is granted to supplement the waiver process or after the waiver has been granted to review the CAD 1 model.
  • 01/01/2007

BIPRU 7.9.15

handbook-guidance

If the FSA grants a CAD 1 model waiver, the waiver direction will specify the particular rule which has been modified, and set out the requirements subject to which the waiver has been granted. These requirements may include:

  1. (1) the details of the calculation of PRR;
  2. (2) the CAD 1 model waiver methodology to be employed;
  3. (3) the products covered by the model (e.g. option type, maturity, currency); and
  4. (4) any notification requirements relating to the CAD 1 model waiver.
  • 01/01/2007

BIPRU 7.9.16

handbook-guidance
Where a firm operates any part of its CAD 1 model outside the United Kingdom, the FSA may take into account the results of any review of that model carried out by any overseas regulator concerned. The FSA may wish to receive information directly from that regulator.
  • 01/01/2007

Maintenance of model recognition

BIPRU 7.9.17

handbook-guidance
No changes should be made to a CAD 1 model unless the change is not material. Material changes to a CAD 1 model will require a renewed waiver to be issued. Materiality is measured from the time that the waiver is granted or, if the waiver has been varied in accordance with section 148 of the Act, any later time that may be specified in the waiver for these purposes. If a firm is considering making material changes to its CAD 1 model, then it should notify the FSA at once. If a firm wishes to change the products covered by the model it should apply for a variation of its CAD 1 model waiver.
  • 01/01/2007

BIPRU 7.9.18

handbook-guidance
If the CAD 1 model ceases to meet the requirements of the waiver, the firm should notify the FSA at once. The FSA may then revoke the waiver unless it is varied in accordance with section 148 of the Act. If the CAD 1 model waiver contains conditions it is a condition of using the CAD 1 model approach that the firm should continue to comply with those conditions.
  • 01/01/2007

Risk management standards

BIPRU 7.9.19

handbook-guidance
A firm with a complex portfolio is expected to demonstrate more sophistication in its modelling and risk management than a firm with a simple portfolio.
  • 01/01/2007

BIPRU 7.9.20

handbook-guidance
A firm should be able to demonstrate that the risk management standards set out in BIPRU 7.9 are satisfied by each legal entity with respect to which the CAD 1 model approach is being used (even though they are expressed to refer only to a firm). This is particularly important for subsidiary undertakings in groups subject to matrix management where the business lines cut across legal entity boundaries.
  • 01/01/2007

BIPRU 7.9.21

handbook-guidance
  1. (1) A firm should have a conceptually sound risk management system which is implemented with integrity and should meet the minimum standards set out in this paragraph.
  2. (2) A firm should have a risk control unit that is independent of business trading units and reports directly to senior management. The unit should be responsible for designing and implementing the firm's risk management system. It should produce and analyse daily reports on the risks run by the business and on the appropriate measures to be taken in terms of the trading limits.
  3. (3) A firm's senior management should be actively involved in the risk control process and the daily reports produced by the risk control unit should be reviewed by a level of management with sufficient authority to enforce reductions of positions taken by individual traders as well as in the firm's overall risk exposure.
  4. (4) The risk control group should have a sufficient number of staff with appropriate skills in the use of models.
  5. (5) A firm should have established procedures for monitoring and ensuring compliance with a documented set of appropriate internal policies and controls concerning the overall operation of the risk measurement and control framework. This should take into account the front, middle and back office functions.
  6. (6) A firm should conduct, as part of its regular internal audit process, a review of the systems and controls relating to its CAD 1 model. This review should include the valuation process, compliance with the CAD 1 model waiver's scope and the activities of the business trading units and the risk control units. This review should be undertaken by staff independent of the areas being reviewed.
  • 01/01/2007

BIPRU 7.9.22

handbook-guidance

In assessing whether the risk management and control framework is implemented with integrity, the FSA will consider the IT systems used to run the CAD 1 model and associated calculations. The assessment will include, where appropriate:

  1. (1) feeder systems; risk aggregation systems; the integrity of the data (i.e. whether it is complete, coherent and correct); reconciliations and checks on completeness of capture; and
  2. (2) system development, change control and documentation; security and audit trails; system availability and contingency procedures; network adequacy.
  • 01/01/2007

BIPRU 7.9.23

handbook-guidance

A firm should take appropriate steps to ensure that it has adequate controls relating to:

  1. (1) the derivation of the PRR from the CAD 1 model output;
  2. (2) CAD 1 model development, including independent validation;
  3. (3) reserving;
  4. (4) valuation (see GENPRU 1.3 (Valuation)), including independent validation; and
  5. (5) the adequacy of the IT infrastructure.
  • 01/01/2007

Model standards

BIPRU 7.9.24

handbook-guidance
A firm should take appropriate steps to ensure that its CAD 1 model captures and produces an accurate measure of the risks inherent in the portfolio covered by the CAD 1 model. These risks may include, but are not limited to, gamma, vega and rho.
  • 01/01/2007

Options risk aggregation models

BIPRU 7.9.25

handbook-guidance
For a firm to obtain a CAD 1 model waiver for its options risk aggregation model, it should have in place an appropriate options valuation model.
  • 01/01/2007

BIPRU 7.9.26

handbook-guidance
The FSA does not specify the methodology that a firm should employ in order to produce the appropriate outputs from its options risk aggregation CAD 1 model. However, BIPRU 7.9.27G - BIPRU 7.9.43G provide details of how a firm could meet the requirement to capture gamma, vega and rho risks using a scenario matrix approach. Where a firm adopts the scenario matrix approach then the standards set out in BIPRU 7.9.27G - BIPRU 7.9.43G should be followed. The firm should also take into account other risks not captured by the scenario matrix approach. If a firm does not use the scenario matrix approach it should use an equivalent methodology. If a firm uses an equivalent methodology it should be able to demonstrate that the approach used meets the requirements of BIPRU 7.9.
  • 01/01/2007

BIPRU 7.9.27

handbook-guidance
A scenario matrix is an approach by which an options portfolio is revalued given a number of simultaneous shifts in both the spot level of the underlying and the implied volatility.
  • 01/01/2007

BIPRU 7.9.28

handbook-guidance
The scenario matrix approach may be employed for all types of options on all types of underlying asset.
  • 01/01/2007

BIPRU 7.9.29

handbook-guidance
  1. (1) This paragraph provides an outline of the initial steps to be taken when using the scenario matrix approach.
  2. (2) A value for an option should be obtained using the firm's options valuation model.
  3. (3) The inputs into the options valuation model for implied volatility of the underlying asset and the price of the underlying asset should then be altered so that a new value for the option is obtained (details of the amount by which the implied volatility and the price of the underlying should be amended are set out in BIPRU 7.9.30G - BIPRU 7.9.36G).
  4. (4) The difference between the original value of the option and the new value obtained following the alterations should be input into the appropriate cell in the matrix. The value in the central cell where there is no change in implied volatility or price of the underlying should therefore be zero.
  5. (5) The process of obtaining a new price for the option should be repeated until the matrix is completed.
  • 01/01/2007

BIPRU 7.9.30

handbook-guidance
The alteration to the implied volatility (known as the implied volatility shift) referred to in BIPRU 7.9.29G (3) may be a proportional shift. The size of the shift depends on the remaining life of the option and the asset class of the underlying. The table in BIPRU 7.9.32G sets out the shifts that should be applied where a proportional shift is used. Alternatively, a firm may use a single shift across all maturities or use an absolute rather than a proportional implied volatility shift. Where a single shift or an absolute shift is used it should be at least as conservative as the proportional shifts. Any use of a single shift or an absolute shift should be reviewed and, if necessary updated, on a regular basis.
  • 01/01/2007

BIPRU 7.9.31

handbook-guidance
A firm may choose to use a less detailed term structure than that in the table in BIPRU 7.9.32G, but the shifts used should be no less conservative than those set out in that table. For example, a firm that uses one <3 month band, rather than the two bands (≤ 1 month and 1-3 months) set out in the table, should use the most conservative shift set out in the table for the bands covered. In this example that shift is 30%.

  • 01/01/2007

BIPRU 7.9.36

handbook-guidance
The minimum size of the scenario matrix should be 3x7, that is, three observations for implied volatility (including the actual implied volatility) and seven observations for the price of the underlying (including the actual price of the underlying). A firm should be able to justify its choice of granularity. Greater granularity may be required where the portfolio contains, for example, a large proportion of barrier options.
  • 01/01/2007

BIPRU 7.9.37

handbook-guidance
  1. (1) A different scenario matrix should be set up for each underlying asset type in accordance with this paragraph.
  2. (2) For equities (including single equities, baskets and indices) there should be a separate matrix for each national market or non-decomposed basket or non-decomposed multi-national index.
  3. (3) For foreign currency products there should be a separate matrix for each currency pair where appropriate.
  4. (4) For commodity products there should be a separate matrix for each commodity. The question whether two items are the same commodity should be decided in accordance with BIPRU 7.4 (Commodity PRR).
  5. (5) For interest rate products there should be a separate matrix for each currency. In addition, a firm should not offset the gamma and vega exposures (except in the circumstances set out in BIPRU 7.9.38G) arising from any one of the following types of product with the gamma and vega exposures arising from any of the other products in the list:
    1. (a) swaptions (options on interest rates);
    2. (b) interest rate options (including options on exchange-traded deposit or bill futures);
    3. (c) bond options (including options on exchange-traded bond futures); and
    4. (d) other types of options required by the CAD 1 model waiver to form their own separate class of underlying asset.
  6. (6) The other types of options referred to in (5)(d) will generally be exotic options that do not fall easily into (5)(a) - (c)).
  7. (7) For CIUs there should be a separate matrix for each CIU fund. If the firm applies one of the CIU look through methods under BIPRU 7.7 (Position risk requirements for collective investment undertakings), then (1) - (6) apply based on what the underlyings are.
  • 01/01/2007

BIPRU 7.9.38

handbook-guidance
A firm may offset gamma and vega exposures arising from the products listed in BIPRU 7.9.37G (5) where it can demonstrate that it trades different types of interest rate-related options as a portfolio and takes steps to control the basis risk between different types of implied volatility. To the extent that this is the case an individual matrix is not required for each of the products listed in BIPRU 7.9.37G (5) and a combined scenario matrix may be used.
  • 01/01/2007

BIPRU 7.9.39

handbook-guidance
Where it is imprudent fully to offset long-dated and short-dated vega exposure owing to the risk of non-parallel shifts in the yield curve, a firm should use an appropriate number of scenario matrices to take account of non-parallel shifts in the yield curve according to the maturity of the option or underlying.
  • 01/01/2007

BIPRU 7.9.40

handbook-guidance
Following the steps outlined in BIPRU 7.9.29G, a firm then removes the portion of the values in the matrix that can be attributed to the effect that delta has had on the change in the value of the option (a process known as delta-stripping).
  • 01/01/2007

BIPRU 7.9.41

handbook-guidance
Once the effect of delta has been removed from the matrix, the values left in the matrix relate to gamma and vega risk. A firm's PRR in relation to gamma and vega risk on the individual option is the absolute of the most negative cell in the scenario matrix produced. Where all cells are positive the PRR is zero. The total PRR for the gamma and vega risk on the portfolio of options is a simple sum of the individual requirements. This amount should then be fed into a firm's PRR calculation.
  • 01/01/2007

BIPRU 7.9.42

handbook-guidance
The values that have been obtained for the delta-equivalent positions of instruments included in the scenario matrix should then be treated in the same way as positions in the underlying. Where the delta obtained relates to interest rate position risk, the delta equivalent positions may be fed into the firm's interest rate pre-processing model to the extent that the positions fall within the scope of interest rate pre-processing models as set out in BIPRU 7.9.7G and provided that the firm's CAD 1 model waiver allows the firm's CAD 1 model to be used in this way. Alternatively, the delta obtained should be fed into the standard PRR calculations in BIPRU 7.2 (Interest rate PRR), BIPRU 7.3 (Equity PRR and basic interest rate PRR for equity derivatives), BIPRU 7.4 (Commodity PRR) or BIPRU 7.5 (Foreign currency PRR) as appropriate.
  • 01/01/2007

BIPRU 7.9.43

handbook-guidance
In using the scenario matrix approach, none of the steps followed will take specific account of a firm's exposure to rho risk. Where a firm can demonstrate that for interest rate-related options the rho sensitivity is effectively included in the delta sensitivities produced, there is no separate capital requirement relating to rho. For all other options except commodity options, a firm should calculate a rho sensitivity ladder by currency using its CAD 1 model and either feed this into the interest rate maturity method or interest rate duration method calculation or, where the firm's CAD 1 model waiver allows the firm's CAD 1 model to be used in this way, feed that ladder into an interest rate pre-processing model. Generally a CAD 1 model does not need to deal specifically with rho risk for commodity options.
  • 01/01/2007

Interest rate pre-processing models

BIPRU 7.9.44

handbook-guidance
To the extent that a firm's CAD 1 model waiver is for the use of an interest rate pre-processing model the firm should use it for the pre-processing of the instruments set out in BIPRU 7.9.7G, from which the residual positions are fed into the interest rate maturity method or interest rate duration method calculation.
  • 01/01/2007

BIPRU 7.9.45

handbook-guidance
There are a number of different methods of constructing pre-processing models but all should comply with BIPRU 7.9.45G - BIPRU 7.9.53G. All pre-processing models should generate positions that have the same sensitivity to defined interest rate changes as the underlying cash flows.
  • 01/01/2007

BIPRU 7.9.46

handbook-guidance
In an interest rate pre-processing model each transaction is converted into its constituent cash flows. The cash flows are discounted using zero coupon rates derived from the firm's own yield curves.
  • 01/01/2007

BIPRU 7.9.47

BIPRU 7.9.48

handbook-guidance
The difference between the present values calculated using the firm's own yield curve and those calculated using the firm's curve shifted under BIPRU 7.9.47G are known as the sensitivity figures. Alternatively, a firm may shift the yield curve by one basis point and multiply up the sensitivity figures by the appropriate amount in order to achieve the shifts set out in BIPRU 7.9.47G. These sensitivity figures are then allocated to each of the 15 maturity bands set out in BIPRU 7.9.49G.

BIPRU 7.9.50

handbook-guidance
Sensitivity figures calculated by a firm using an interest rate pre-processing model are usually produced in the format of a net sensitivity by maturity bucket or by discrete gridpoint. These maturity buckets or gridpoints should then be allocated to the 15 bands set out in BIPRU 7.9.49G. The number of maturity buckets or gridpoints used to represent a yield curve can be referred to as granularity. The granularity should always be adequate to capture the material curve risk in the portfolio. Curve risk can be defined as the risk associated with holding long and short positions at different points along the yield curve.

BIPRU 7.9.51

handbook-guidance
Positive and negative amounts placed in each of the different maturity bands in BIPRU 7.9.49G under the sensitivity calculation in BIPRU 7.9.50G should then be netted off to produce one figure for each of the bands. There is no capital requirement for this netting process.
  • 01/01/2007

BIPRU 7.9.52

The individual sensitivity figures produced should then be input into the interest rate duration method calculation.

Use of a Value at Risk Model

  • 01/01/2007

Application

BIPRU 7.10.1

handbook-rule
BIPRU 7.10 applies to a firm with a VaR model permission.
  • 01/01/2007

Introduction and purpose

BIPRU 7.10.2

handbook-guidance
BIPRU 7.10 provides details of when the FSA expects to allow a firm to use a VaR model (value at risk model) for the purpose of calculating part or all of its PRR. It introduces the concept of a VaR model, the methodology behind it and the link to the standard market risk PRR rules. It then goes on to detail the application and review process. The bulk of BIPRU 7.10 specifies the model standards and risk management standards that firms will be required to meet in order to use a VaR model. It further stipulates requirements for stress testing, backtesting, capital calculations and finally the reporting standards expected by the FSA.
  • 01/01/2007

BIPRU 7.10.3

handbook-guidance
The models described in BIPRU 7.10 are described as VaR models in order to distinguish them from CAD 1 models, which are dealt with in BIPRU 7.9 (Use of a CAD 1 model). A VaR model is a risk management model which uses a statistical measure to predict profit and loss movement ranges with a confidence interval. From these results PRR charges can be calculated. The standards described in BIPRU 7.10, and which will be applied by the FSA , are based on and implement Annex V of the Capital Adequacy Directive.
  • 01/01/2007

BIPRU 7.10.4

handbook-guidance
The aim of the VaR model approach is to enable a firm with adequate risk management systems to be subject to a PRR requirement that is more closely aligned with the risks to which it is subject than the PRR requirements generated by the standard market risk PRR rules. This provides a firm with an incentive to measure market risks as accurately and comprehensively as possible. It is crucial that those responsible for managing market risk at a firm should be aware of the assumptions and limitations of the firm's VaR model.
  • 01/01/2007

BIPRU 7.10.5

handbook-guidance
There are a number of general methodologies for calculating PRR using a VaR model. The FSA does not prescribe any one method of computing VaR measures. Moreover, it does not wish to discourage any firm from developing alternative risk measurement techniques. A firm should discuss the use of any alternative techniques used to calculate PRR with the FSA.
  • 01/01/2007

BIPRU 7.10.6

handbook-guidance
A firm should not use the VaR model approach to calculate PRR unless it has a VaR model permission. If a firm does not have such a permission it should use the standard market risk PRR rules. Therefore, a firm needs to apply for a VaR model permission in order to calculate its PRR using a VaR model instead of (or in combination with) the standard market risk PRR rules.
  • 01/01/2007

Conditions for granting a VaR model permission

BIPRU 7.10.7

A waiver or other permission allowing the use of models in the calculation of PRR will not be granted if that would be contrary to the Capital Adequacy Directive and any VaR model permission which is granted will only be granted on terms that are compatible with the Capital Adequacy Directive. Accordingly, the FSA is likely only to grant a waiver or other permission allowing the use of models in the calculation of PRR if it is a VaR model permission or a CAD 1 model waiver.

BIPRU 7.10.8

handbook-guidance

BIPRU 7.10 sets out the minimum standards that the FSA expects firms to meet before granting a VaR model permission. The FSA will not grant a VaR model permission unless it is satisfied that the requirements of BIPRU 7.10 are met and it is satisfied about the procedures in place at a firm to calculate the model PRR. In particular the FSA will not normally grant a VaR model permission unless it is satisfied about the quality of:

  1. (1) the internal controls and risk management relating to the VaR model (see BIPRU 7.10.56G - BIPRU 7.10.82R);
  2. (2) the VaR model standards (see BIPRU 7.10.24R-BIPRU 7.10.55G); and
  3. (3) stress testing and backtesting procedures relating to a VaR model (see, in addition to (2), BIPRU 7.10.83R - BIPRU 7.10.112G).
  • 01/01/2007

BIPRU 7.10.9

handbook-guidance
The FSA recognises that the nature of VaR models will vary between firms. The scope of and the requirements and conditions set out in a VaR model permission may therefore differ in substance or detail from BIPRU 7.10 in order to address individual circumstances adequately. However any differences will only be allowed if they are compliant with the Capital Adequacy Directive. A VaR model permission will implement any such variation by modifying BIPRU 7.10. A VaR model permission may also include additional conditions to meet the particular circumstances of the firm or the model.

The VaR model permission application and review process

BIPRU 7.10.10

handbook-guidance
Details of the general process for applying for a VaR model permission are set out in BIPRU 1.3 (Applications for advanced approaches). Because of the complexity of a VaR model permission, it is recommended that a firm discuss its proposed application with its usual contact at the FSA before it makes the application.
  • 01/01/2007

BIPRU 7.10.11

handbook-guidance
In order for a VaR model permission to be granted, the FSA is likely to undertake a review to ensure that it is adequate and appropriate for the PRR calculation.
  • 01/01/2007

BIPRU 7.10.12

handbook-guidance
The VaR model review process may be conducted through a series of visits covering various aspects of a firm's control and IT environment. Before these visits the FSA may ask the firm to provide some information relating to the firm's VaR model permission request accompanied by some specified background material. The VaR model review visits are organised on a timetable that allows the firm being visited sufficient time to arrange the visit and provide the appropriate pre-visit information.
  • 01/01/2007

BIPRU 7.10.13

handbook-guidance
As part of the process for dealing with an application for a VaR model permission the following may be reviewed: organisational structure and personnel; details of the firm's market position in the relevant products; revenue and risk information; valuation and reserving policies; operational controls; information technology systems; model release and control procedures; risk management and control framework; risk appetite and limit structure; future developments relevant to model recognition.
  • 01/01/2007

BIPRU 7.10.14

A visit will usually involve the FSA wishing to meet senior management and staff from the front office, financial control, risk management, operations, systems development, information technology and internal audit areas.
  • 01/01/2007

BIPRU 7.10.15

handbook-guidance
The FSA may complement its own review of a VaR model permission request with one or more reviews by a skilled person under section 166 of the Act (Reports by skilled persons). Such a review may also be used where a VaR model permission has been granted to ensure that the requirements BIPRU 7.10 and of the VaR model permission continue to be met.

Where a firm operates any part of its VaR model outside the United Kingdom, the FSA may take into account the results of the home supervisor's review of that model. The FSA may wish to receive information directly from the home supervisor.
  • 01/01/2007

Scope of VaR models

BIPRU 7.10.18

handbook-rule

A firm must use the VaR model approach to calculate the PRR for a position:

  1. (1) to the extent that the risks in relation to that position are within the scope of the VaR model permission (see BIPRU 7.10.136R (Link to standard PRR rules: Incorporation of the model output into the capital calculation)); and
  2. (2) if the position is of a type that comes within the scope of the VaR model permission.
  • 01/01/2007

BIPRU 7.10.19

handbook-guidance

In accordance with BIPRU 7.10.18R (1) a VaR model permission will set out the risk categories that it covers, which are expected to be one or more of the following types:

  1. (1) interest rate general market risk;
  2. (2) interest rate specific risk (in conjunction with interest rate general market risk);
  3. (3) equity general market risk;
  4. (4) equity specific risk (in conjunction with equity general market risk);
  5. (5) CIU risk;
  6. (6) foreign currency risk; and
  7. (7) commodity risk.
  • 01/01/2007

BIPRU 7.10.20

handbook-guidance
A VaR model permission will generally set out the broad classes of position within its scope. It may also specify how individual products within one of those broad classes may be brought into or taken out of the scope of the VaR model permission.
  • 01/01/2007

BIPRU 7.10.21

handbook-guidance

The broad classes of position referred to in BIPRU 7.10.20G are as follows:

  1. (1) linear products, which comprise securities with linear pay-offs (e.g. bonds and equities) and derivative products which have linear pay-offs in the underlying risk factor (e.g. interest rate swaps, FRAs, total return swaps);
  2. (2) European, American and Bermudan put and call options (including caps, floors and swaptions) and investments with these features (see BIPRU 7.6.18R (Table: Option PRR: methods for different types of option) for an explanation of some of these terms);
  3. (3) Asian options, digital options, single barrier options, double barrier options, lookback options, forward starting options, compound options and investments with these features (see BIPRU 7.6.18R for an explanation of some of these terms); and
  4. (4) all other option based products (e.g. basket options, quantos, outperformance options, timing options) and investments with these features (see BIPRU 7.6.18R for an explanation of some of these terms).

The categorisation described in BIPRU 7.10.21G may be amended or replaced in the case of a particular firm's VaR model permission.
  • 01/01/2007

BIPRU 7.10.23

handbook-guidance
It is the FSA's view that, where a firm uses a VaR model for one risk category as described in BIPRU 7.10.19G, it is good practice to extend its model over time to calculate all of its PRR risk categories. A firm will typically be expected to have a realistic plan in place to do this.
  • 01/01/2007

Model standards: General

BIPRU 7.10.24

handbook-rule
A firm must comply with the minimum standards set out in BIPRU 7.10.26R - BIPRU 7.10.53R in calculating the model PRR.
  • 01/01/2007

BIPRU 7.10.25

handbook-guidance
The FSA accepts that the scope and nature of VaR models varies across firms. This means that different firms are likely to calculate different estimates of market risk for the same portfolio. Systematic differences are due to length of data series, choice of methodology (historical or Monte Carlo simulation or variance-covariance method or a hybrid of these), differences in aggregating risks within and across broad risk factors, the treatment of options and other non-linear products and the specification of risk factors.
  • 01/01/2007

Model standards: Frequency of calculations and confidence level

BIPRU 7.10.26

handbook-rule
The model PRR must be computed at least once every business day, using a 99% one-tailed confidence limit.
  • 01/01/2007

BIPRU 7.10.27

handbook-guidance
A firm may meet the requirement in BIPRU 7.10.26R by using different model parameters and employing a suitable adjustment mechanism to produce a figure which is equivalent to the figure produced using the parameters set out in BIPRU 7.10.26R. For example, a firm's model may use a 95% one-tailed confidence limit if the firm has a mechanism to convert the output of the model to reflect a 99% one-tailed confidence limit.
  • 01/01/2007

Model standards: Holding period

BIPRU 7.10.28

handbook-rule
In calculating the VaR number, a firm must either use a ten business day holding period, or use a holding period converted to a ten business day holding period. However if the firm's VaR model permission specifies that the firm must use a specific method, the firm must do so.
  • 01/01/2007

BIPRU 7.10.29

handbook-guidance
If a firm uses a holding period other than 10 business days and converts the resulting VaR measure to a ten business day equivalent measure, it should be able to justify the choice of conversion technique. For example, the square root of time method will usually be justifiable. The FSA considers it good practice ultimately to move towards the application of an actual ten business day holding period, rather than using different holding periods.
  • 01/01/2007

Model standards: Observation period

BIPRU 7.10.30

handbook-rule
Subject to BIPRU 7.10.31R, the calculation of VaR numbers must be based on an effective historical observation period that is the longest possible consistent with a prudent VaR number. That period must be at least one year or such longer period as may be set out in the firm's VaR model permission. However if using that prescribed observation period does not result in a sufficiently prudent way of calculating a VaR measure or a component of a VaR measure the firm must shorten this observation period until the observation period is consistent with a prudent VaR number.
  • 01/01/2007

Model standards: Data series

BIPRU 7.10.31

handbook-rule
A firm must ensure that the data series used by its VaR model is reliable. Where a reliable data series is not available, proxies or any other reasonable value-at-risk measurement technique must be used. A firm must be able to demonstrate that the technique is appropriate and does not materially understate the modelled risks.
  • 01/01/2007

BIPRU 7.10.32

handbook-guidance
A data series is unreliable if it has, for example, missing data points, or data points which contain stale data. Reliable data series may be difficult to obtain for new products (for example an instrument of longer dated tenor that did not previously trade) and for less liquid risk factors or positions. With regard to less liquid risk factors or positions, a firm may use a combination of prudent valuation techniques and alternative VaR estimation techniques to ensure there is a sufficient cushion against risk over the close out period which takes account of the illiquidity of the risk factor or position.
  • 01/01/2007

BIPRU 7.10.33

handbook-rule
  1. (1) If a weighting scheme or other similar method is used to calculate VaR numbers, then the effective observation period must be at least one year. Where a weighting scheme is used, the weighted average time lag of the individual observations must not be less than six Months.
  2. (2) If a specific observation period or weighted average time lag is specified in a firm's VaR model permission, the firm must comply with that if it is longer than the period specified in (1).
  3. (3) However, if a weighting scheme in (1) or (2) would result in imprudent VaR numbers then the weighting scheme must be adjusted so that it is consistent with a prudent VaR number.
  • 01/01/2007

BIPRU 7.10.34

handbook-rule
A firm must update data sets in accordance with the frequency set out in its VaR model permission. If volatility in market prices or rates necessitates more frequent updating in order to ensure a prudent calculation of the VaR measure the firm must do so.
  • 01/01/2007

BIPRU 7.10.35

handbook-guidance
The minimum updating frequency that can be specified in a VaR model permission is quarterly.
  • 01/01/2007

Model standards: Aggregation across risk categories

BIPRU 7.10.36

handbook-rule
The process for determining and implementing correlations within and across risk categories must be sound, implemented with integrity and consistent with the terms of the firm's VaR model permission.
  • 01/01/2007

BIPRU 7.10.37

handbook-rule

In aggregating VaR measures across risk or product categories, a firm must not use the square root of the sum of the squares approach unless the assumption of zero correlation between these categories is empirically justified. If correlations between risk categories are not empirically justified, the VaR measures for each category must simply be added in order to determine its aggregate VaR measure. But to the extent that a firm's VaR model permission provides for a different way of aggregating VaR measures:

  1. (1) that method applies instead of this rule; and
  2. (2) if the correlations between risk categories used for that purpose cease to be empirically justified then the firm must notify the FSA at once.

Model standards: Risk factors: Introduction

BIPRU 7.10.38

handbook-guidance
Subject to BIPRU 7.10.53R (Model standards: Materiality), a VaR model should capture and accurately reflect all material risks arising on the underlying portfolio on a continuing basis insofar as those risks are within the scope of the VaR model permission. This should encompass general market risk and, to the extent that this comes within the scope of the VaR model permission, specific risk. A firm should ensure that the VaR model has sufficient risk factor granularity to be able to capture all such material risks and that these are properly documented and specified.

Model standards: Risk factors: General

BIPRU 7.10.39

handbook-rule
In the case of general market risk and risks with respect to which the standard market risk PRR rules do not distinguish between general market risk and specific risk, a firm's VaR model must capture a sufficient number of risk factors in relation to the level of activity of the firm and in particular the risks set out in BIPRU 7.10.40R - BIPRU 7.10.44R.
  • 01/01/2007

BIPRU 7.10.40

handbook-rule
For interest rate risk, a VaR model must incorporate a set of risk factors corresponding to the interest rate curves in each currency in which the firm has interest rate sensitive positions. A firm must ensure that it captures the variations of volatility of rates along the yield curve. In order to achieve this, a firm must divide the yield curves of, at a minimum, the major currencies and markets in which it has material interest rate exposures into a minimum of six maturity segments. The VaR model must also capture the risk of less than perfectly correlated movements between different yield curves.
  • 01/01/2007

BIPRU 7.10.41

For foreign currency risk, a VaR model must incorporate risk factors corresponding to the individual foreign currencies, including gold, in which the firm's positions are denominated.
  • 01/01/2007

BIPRU 7.10.43

handbook-rule
For commodity risk, the VaR model must use a separate risk factor at least for each commodity in which the firm has material positions. The VaR model must also capture the risk of less than perfectly correlated movements between similar, but not identical, commodities and the exposure to changes in forward prices arising from maturity mismatches. It must also take account of market characteristics, notably delivery dates and the scope provided to traders to close out positions.
  • 01/01/2007

BIPRU 7.10.44

  1. (1) For CIUs the actual foreign currency positions of the CIU must be taken into account.
  2. (2) A firm may rely on third party reporting of the foreign currency position of the CIU, where the correctness of this report is adequately ensured.
  3. (3) If a firm is not aware of the foreign currency positions in a CIU, this position must be carved out and treated in BIPRU 7.5.18R (Derivation of notional positions in CIUs for the foreign currency PRR).
  • 01/01/2007

BIPRU 7.10.45

handbook-guidance
  1. (1) This paragraph contains guidance on the inclusion of CIUs in a VaR model.
  2. (2) The FSA may allow all types of CIU to be included within the scope of a firm's VaR model permission.
  3. (3) BIPRU 7.10 does not distinguish between specific risk and general market risk for positions in CIUs. Therefore even if specific risk is not otherwise included within the scope of a firm's VaR model permission, a firm should be able to demonstrate that its VaR model captures specific risk.
  4. (4) A firm should also be able to demonstrate that its VaR model adequately captures correlations, concentration risk and risks associated with the illiquidity of the CIU itself should this be deemed necessary (see BIPRU 7.10.32G).
  5. (5) A firm may use a look-through approach, under which the VaR model estimates are based on the underlying positions. If a firm uses a look through approach it should also ensure that all the relevant risk factors relating to the underlying positions are captured. BIPRU 7.7 (Position risk requirements for collective investment undertakings) sets out rules relating to the look through approach when a firm is using the VaR model approach.

  1. (1) If a firm's VaR model covers the calculation of PRR with respect to specific risk the firm must meet the VaR specific risk minimum requirements in addition to the other requirements of BIPRU 7.10.
  2. (2) The VaR model must explain the historical price variation in the portfolios concerned.
  3. (3) The VaR model must capture concentration in terms of magnitude and changes of composition of the portfolios concerned.
  4. (4) The VaR model must be robust to an adverse environment.
  5. (5) The VaR model must capture name-related basis risk. That is the firm must be able to demonstrate that the VaR model is sensitive to material idiosyncratic differences between similar but not identical positions.
  6. (6) The VaR model must capture event risk.
  7. (7) In addition to the other requirements in BIPRU 7.10, a firm must have an approach in place to capture, in the calculation of its capital requirements, the default risk of its trading book positions that is incremental to the default risk captured by the VaR measures as specified in this rule, BIPRU 7.10.48R, BIPRU 7.10.49R and BIPRU 7.10.107R (Backtesting: Specific risk backtesting).
  8. (8) A firm must be able to demonstrate that the approach referred to in (7) meets soundness standards comparable to the approach set out in BIPRU 4 (The IRB approach), under the assumption of a constant level of risk, and adjusted where appropriate to reflect the impact of liquidity, concentrations, hedging and optionality.
  • 01/11/2007

BIPRU 7.10.47

handbook-guidance
This paragraph provides guidance on BIPRU 7.10.46R (3). Take as an example a VaR model based on a factor model or on a historical simulation model. The ability of the model to explain price variation could be demonstrated by a statistical comparison over the same period of time between actual price changes on the portfolio and the profit and loss impact of risk factors included within the model. A firm may wish to include an estimate of residual variation not explained by the model.
  • 01/01/2007

BIPRU 7.10.48

handbook-rule
  1. (1) Where a firm is subject to event risk that is not reflected in its VaR measure, because it is beyond the 10-day holding period and 99 percent confidence interval (low probability and high severity events), the firm must ensure that the impact of such events is factored into its internal capital assessment.
  2. (2) A firm's VaR model must conservatively assess the risk arising from less liquid positions and positions with limited price transparency under realistic market scenarios. In addition, the VaR model must meet minimum data standards. Proxies must be appropriately conservative and may be used only where available data is insufficient or is not reflective of the true volatility of a position or portfolio.

  • 01/01/2007

BIPRU 7.10.50

handbook-rule
To avoid double counting capital requirements under BIPRU 7.10.46R (7) a firm may, when calculating its incremental default charge, take into account the extent to which default risk has already been incorporated into the VaR calculation, especially for risk positions that could and would be closed within 10 business days in the event of adverse market conditions or other indications of deterioration in the credit environment. Where a firm captures its incremental default risk through a surcharge, it must have in place methodologies for validating the measure.
  • 01/01/2007

BIPRU 7.10.51

handbook-rule
A firm that does not capture the incremental default risk through an internally developed approach must calculate the surcharge through an approach consistent with either the standardised approach to credit risk or the IRB approach.
  • 01/01/2007

BIPRU 7.10.52

handbook-rule
With respect to securitisation exposures that would be subject to a deduction treatment in the calculation of its capital resources or risk weighted at 1250% as set out in BIPRU 9, these positions (cash or synthetic) are subject to a capital charge that is no less than set forth under that treatment. A firm that is a dealer in these exposures may apply a different treatment where it could demonstrate to the FSA, in addition to trading intent, that a liquid two-way market exists for the securitisation exposures or, in the case of synthetic securitisation that rely solely on credit derivatives, for the securitisation exposures themselves or all their constituent risk components. For the purposes of this rule a two-way market is deemed to exist where there are independent good faith offers to buy and sell so that a price reasonably related to the last sales price or current good faith competitive bid and offer quotations can be determined within one day and settled at such a price within a relatively short time conforming to trade custom. For a firm to apply a different treatment, it must have sufficient market data to ensure that it fully captures the concentrated default risk of these exposures in its internal approach for measuring the incremental default risk in accordance with the VaR specific risk minimum requirements.
  • 01/01/2007

Model standards: Materiality

BIPRU 7.10.53

handbook-rule
A firm's VaR model must capture accurately all material price risks for positions within the scope of its VaR permission, including risks relating to options or option-like positions. The firm must ensure that, if its VaR model does not accurately capture any material risk, the firm has capital resources adequate to cover that risk. These capital resources must be additional to those required to meet its capital resources requirement.
  • 01/01/2007

BIPRU 7.10.54

handbook-guidance
For example, BIPRU 7.10.53R might involve creating and documenting a prudent incremental PRR charge for the risk not captured in the VaR model and holding sufficient capital resources against this risk. In that case the firm should hold capital resources at least equal to its capital resources requirement as increased by adding this incremental charge to the model PRR. Alternatively the firm may make valuation adjustments through its profit and loss reserves to cover this material risk. These reserves should be transparent to senior management and auditable. The reserves should also be consistent with GENPRU 1.3 (Valuation) while not being excessive in relation to the principles of mark-to-market accounting. Therefore, a firm should be able to satisfy the FSA that all material risks are adequately addressed, whether this be through the VaR model, through taking an incremental PRR charge or through making an adjustment through profit and loss reserves.
  • 01/01/2007

BIPRU 7.10.55

handbook-guidance
A firm is expected ultimately to move towards full revaluation of option positions. For portfolios containing path dependent options, an instantaneous price shock applied to a static portfolio will be acceptable provided that the risks not captured by such an approach are not material. Where a risk is immaterial and does not justify further capital resources, that immaterial risk should still be documented.
  • 01/01/2007

Risk management standards: Introduction

BIPRU 7.10.56

handbook-guidance
A firm with a complex portfolio is expected to demonstrate greater sophistication in its modelling and risk management than a firm with a simple portfolio. For example, a firm will be expected to consider, where necessary, varying degrees of liquidity for different risk factors, the complexity of risk modelling across time zones, product categories and risk factors. Some trade-off is permissible between the sophistication and accuracy of the model and the conservatism of underlying assumptions or simplifications.
  • 01/01/2007

  1. (1) A firm must frequently conduct a rigorous programme of stress testing. The results of these tests must be reviewed by senior management and reflected in the policies and limits the firm sets.
  2. (2) The programme must particularly address:
    1. (a) concentration risk;
    2. (b) illiquidity of markets in stressed market conditions;
    3. (c) one way markets;
    4. (d) event and jump to default risks;
    5. (e) non linearity of products;
    6. (f) deep out of the money positions;
    7. (g) positions subject to the gapping of prices;

    11. (k) secondary risk factors (such as volatility);
    12. (l) basis risk;
    13. (m) systemic and localised stresses; and
    14. (n) other risks that may not be captured appropriately in the VaR model (for example, recovery rate uncertainty, implied correlations and skew risk).

Risk management standards: Risk review

BIPRU 7.10.75

handbook-rule

At least once a year, a firm must conduct, as part of its regular internal audit process, a review of its risk management process. This review must include both the activities of the business trading units and of the independent risk control unit, and must be undertaken by suitably qualified staff independent of the areas being reviewed. This review must consider, at a minimum:

  1. (1) the adequacy of the documentation of the risk management system and process;
  2. (2) the organisation of the risk control unit;
  3. (3) the integration of market risk measures into daily risk management;
  4. (4) the integrity of the management information system;
  5. (5) the process for approving risk pricing models and valuation systems used in front and back offices;
  6. (6) the validation of any significant changes in the risk management process;
  7. (7) the scope of risks and products captured by the VaR model;
  8. (8) the accuracy and completeness of position data;

  • 01/01/2007

BIPRU 7.10.77

handbook-guidance
In assessing the firm's VaR model and risk management, the FSA has regard to the results of internal model validation procedures used by the firm to assess the VaR model.
  • 01/01/2007

BIPRU 7.10.78

handbook-rule

A firm must have processes in place to ensure that its VaR model has been adequately validated by suitably qualified parties independent of the development process to ensure that it is conceptually sound and adequately captures all material risks. This validation must be conducted when the VaR model is initially developed and when any significant changes are made to the VaR model. The validation must also be conducted on a periodic basis but especially where there have been any significant structural changes in the market or changes to the composition of the portfolio which might lead to the VaR model no longer being adequate. As techniques and best practices evolve, a firm must avail itself of these advances. Model validation must not be limited to backtesting, but must, at a minimum, also include the following:

  1. (1) tests to demonstrate that any assumptions made within the VaR model are appropriate and do not underestimate or overestimate the risk (including testing of the validity of the assumptions and approximations underlying the VaR model);
  2. (2) in addition to the regulatory backtesting programmes, a firm must carry out its own model validation tests in relation to the risks and structures of its portfolios, such as statistical validation techniques and other methods of measuring performance and validity;
  3. (3) the use of hypothetical portfolios to ensure that the VaR model is able to account for particular structural features that may arise, for example material basis risks and concentration risk; and
  4. (4) investigation of the limitations of the VaR model including testing of the accuracy of parts of the VaR model as well as of the whole.
  • 01/01/2007

BIPRU 7.10.79

handbook-guidance
  1. (1) In addition to regulatory backtesting programs, testing for model validation should be carried out using additional tests which may include for example:
    1. (a) testing carried out using hypothetical changes in portfolio value that would occur were end of day positions to remain unchanged;
    2. (b) testing carried out for longer periods than required for the regular backtesting programme (for example, 3 years);
    3. (c) testing carried out using confidence intervals other than the 99 percent interval required under the quantitative requirements in BIPRU 7.10; and
    4. (d) testing of parts of portfolios.
  2. (2) A longer time period generally improves the power of backtesting. However a longer time period may not be desirable if the VaR model or market conditions have changed to the extent that historical data is no longer relevant.

BIPRU 7.10.81

handbook-guidance

In assessing whether the VaR model is implemented with integrity as described in BIPRU 7.10.58R (Stress testing), the FSA will consider in particular the information technology systems used to run the model and associated calculations. The assessment may include:

  1. (1) feeder systems; risk aggregation systems; time series databases; the VaR model system; stress testing system; the backtesting system including profit and loss cleaning systems where appropriate; data quality; reconciliations and checks on completeness of capture;
  2. (2) system development, change control and documentation; security and audit trails; system availability and contingency procedures; network adequacy; and

  • 01/01/2007

BIPRU 7.10.84

handbook-guidance
Stress testing is a way of identifying the risk to a firm posed by a breakdown of model assumptions or by low-probability events. Where stress tests reveal unacceptable vulnerability to a given set of circumstances, a firm should take prompt steps to manage those risks appropriately, for example by hedging against the outcome or reducing the size of the firm's exposure.

BIPRU 7.10.87

handbook-rule
A firm must periodically and actively identify all the worst case scenarios that are relevant to its portfolio. Scenarios used must be appropriate to test the effect of adverse movements in market volatilities and correlations and the effect of any change in the assumptions underlying the VaR model. Scenarios involving low probability market events must nevertheless be plausible.

Backtesting: Introduction

BIPRU 7.10.91

handbook-guidance
Backtesting is the process of comparing value-at-risk risk measures to portfolio performance. It is intended to act as one of the mechanisms for the ongoing validation of a firm's VaR model and to provide incentives for firms to improve their VaR measures.
  • 01/01/2007

BIPRU 7.10.92

handbook-guidance
It is a condition for granting a VaR model permission that a firm should have a backtesting programme in place and should provide three months of backtesting history.
  • 01/01/2007

BIPRU 7.10.93

handbook-guidance
Backtesting conducted only at a whole portfolio level using a single measure of profit and loss has limited power to distinguish an accurate VaR model from an inaccurate one. Backtesting should therefore be regarded as an additional safeguard rather than a primary validation tool. Such testing does however form the basis of the FSA's plus factor system. The test has been chosen as the basis of the backtesting regime because of its simplicity. A firm will therefore be expected to complement this backtesting with more granular backtesting analysis and involving more than one measure of profit and loss (i.e. both a clean profit and loss figure and a clean hypothetical profit and loss figure).
  • 01/01/2007

BIPRU 7.10.94

handbook-rule
A firm must have the capacity to analyse and compare its clean profit and loss figures and clean hypothetical profit and loss figures to the VaR measure, both at the level of the whole portfolio covered by the VaR model permission and at the level of individual books that contain material amounts of risk.
  • 01/01/2007

BIPRU 7.10.95

handbook-guidance
Clean profit and loss backtesting should be used for regulatory backtesting and used to calculate plus factors. Hypothetical profit and loss backtesting is used for model validation and for reporting to the FSA.
  • 01/01/2007

Backtesting: Basic testing requirements

BIPRU 7.10.96

handbook-rule
A firm must, on each business day, compare each of its 250 most recent business days' clean profit and loss figures (ending with the business day preceding the business day in question) with the corresponding one-day VaR measures.
  • 01/01/2007

BIPRU 7.10.97

handbook-guidance
Generally the positions underlying the profit and loss account and VaR measures should not be materially different.
  • 01/01/2007

Backtesting: One day VaR measure

BIPRU 7.10.98

handbook-rule
The one-day VaR measure for a particular business day is the VaR number for that business day calibrated to a one business day holding period and a 99% one-tailed confidence level.
  • 01/01/2007

Backtesting: Calculating the clean profit and loss

BIPRU 7.10.99

handbook-guidance
The ultimate purpose of backtesting is to assess whether capital is sufficient to absorb actual losses. Therefore backtesting should be performed using a measure of actual daily profit and loss. Actual daily profit and loss means the day's profit and loss arising from trading activities within the scope of the VaR model permission. This measure should, however, be 'cleaned' using BIPRU 7.10.100R inclusion in profit and loss of non-modelled factors.
  • 01/01/2007

BIPRU 7.10.100

handbook-rule

The clean profit and loss figure for a particular business day is the firm's actual profit or loss for that day in respect of the trading activities within the scope of the firm's VaR model permission, adjusted by stripping out:

  1. (1) fees and commissions;
  2. (2) brokerage;
  3. (3) additions to and releases from reserves which are not directly related to market risk (e.g. administration reserves); and
  4. (4) any inception profit exceeding an amount specified for this purpose in the firm's VaR model permission (where inception profit is defined as any profit arising immediately on entering into a new transaction).
  • 01/01/2007

BIPRU 7.10.101

handbook-guidance
The definition of clean profit and loss figure may be amended or replaced in an individual VaR model permission if the firm can demonstrate to the FSA that the alternative method meets the spirit and purpose of the provisions in BIPRU 7.10 about the clean profit and loss figure.
  • 01/01/2007

BIPRU 7.10.102

handbook-guidance
The FSA will review as part of a firm's VaR model permission application the processes and documentation relating to the derivation of profit and loss used for backtesting. A firm's documentation should clearly set out the basis for cleaning profit and loss. To the extent that certain profit and loss elements are not updated every day (for example certain reserve calculations) the documentation should clearly set out how such elements are included in the clean profit and loss series.
  • 01/01/2007

Backtesting: Definition of backtesting exception

BIPRU 7.10.103

handbook-rule
A backtesting exception is deemed to have occurred for any business day if the clean profit and loss figure for that business day shows a loss, which in absolute magnitude, exceeds the one-day VaR measure for that business day. The only exception is if that business day is identified in the firm's VaR model permission as giving rise to an excluded backtesting exception.
  • 01/01/2007

Backtesting: Obligation to notify the FSA

BIPRU 7.10.104

handbook-rule
If a backtesting exception occurs, the firm must notify its usual supervisory contact at the FSA orally by close of business two business days after the business day for which the backtesting exception occurred. Within five business days following the end of each Month, the firm must submit to the FSA a written account of the previous Month's backtesting exceptions (if any). This explanation must include the causes of the backtesting exceptions, an analysis of whether the backtesting exception indicate a deficiency in the firm's VaR model and the firm's planned response (if any).
  • 01/01/2007

Backtesting: Summary of the backtesting cycle

BIPRU 7.10.105

handbook-guidance
  1. (1) This paragraph gives guidance on the backtesting calculation and reporting process in BIPRU 7.10.96R - BIPRU 7.10.104R.
  2. (2) Let the day on which the loss referred to in BIPRU 7.10.100R is made be day n. The value-at-risk measure for that day will be calculated on day n-1, or overnight between day n-1 and day n. Profit and loss figures are produced on day n+1, and backtesting also takes place on day n+1. The firm's supervisor should be notified of any backtesting exceptions by close of business on day n+2.
  3. (3) Any backtesting exception initially counts for the purpose of the calculation of the plus factor even if subsequently the FSA agrees to exclude it under the process described in BIPRU 7.10.106G. Thus, where the firm experiences a backtesting exception and already has four or more backtesting exceptions for the previous 250 business days, changes to the multiplication factor arising from changes to the plus factor become effective at n+3 (using the time-line terminology in (2)).
  • 01/01/2007

Backtesting: Process for disregarding backtesting exceptions

BIPRU 7.10.106

handbook-guidance
  1. (1) This paragraph gives guidance on the process for excluding backtesting exceptions as referred to in BIPRU 7.10.103R.
  2. (2) The FSA will respond flexibly to backtesting exceptions. However, the FSA's starting assumption will be that a backtesting exception should be taken into account for the purpose of the calculation of plus factors. If the firm believes that a backtesting exception should not count for that purpose, then it should seek a variation of its VaR model permission in order to exclude that particular backtesting exception. The FSA will then decide whether to agree to such a variation.
  3. (3) One example of when a firm's backtesting exception might properly be disregarded is when it has arisen as a result of a risk that is not captured in its VaR model but against which capital resources are already held.
  • 01/01/2007

Backtesting: Specific risk backtesting

BIPRU 7.10.107

handbook-rule
If a firm's VaR model permission covers specific risk, the firm must validate its VaR model through backtesting aimed at assessing whether specific risk is being accurately captured. This backtesting must be carried out in accordance with the provisions of its VaR model permission. If the VaR model permission provides for this backtesting to be performed on the basis of relevant sub-portfolios, these must be chosen in a consistent manner.
  • 01/01/2007

BIPRU 7.10.108

handbook-guidance
Specific risk backtesting involves the backtesting of a standalone specific risk VaR measure against a profit and loss series determined by reference to exposure risk factors categorised as specific risk. Alternatively specific risk backtesting may take the form of regular backtesting of trading books and portfolios that are predominantly exposed to risk factors categorised as specific risk. The precise requirements for specific risk backtesting will be specified in the firm's VaR model permission as will the definition of a specific risk backtesting exception.
  • 01/01/2007

Backtesting: Multiple exceptions

BIPRU 7.10.109

handbook-rule
If ten or more backtesting exceptions or ten or more specific risk backtesting exceptions are recorded in a 250 business day period, a firm must take immediate corrective action.
  • 01/01/2007

BIPRU 7.10.110

handbook-guidance
Where backtesting reveals severe problems with the basic integrity of the VaR model, the FSA may withdraw model recognition. In particular, if ten or more backtesting exceptions are recorded in a 250 business day period, the FSA may apply a plus factor greater than one or the FSA may consider revoking a firm's VaR model permission. The FSA may also consider revoking a firm's VaR model permission if ten or more specific risk backtesting exceptions occur in such a period.
  • 01/01/2007

Backtesting: Hypothetical profit and loss

BIPRU 7.10.111

handbook-rule
A firm must also perform backtesting against a clean hypothetical profit and loss figure with respect to each business day. A clean hypothetical profit and loss figure for a business day means the clean profit and loss figure that would have occurred for that business day if the portfolio on which the VaR number for that business day is based remained unchanged.
  • 01/01/2007

BIPRU 7.10.112

handbook-guidance
  1. (1) A clean hypothetical profit and loss figure is based on the day's change in the value of the same portfolio that was used to generate the value-at-risk forecast.
  2. (2) Backtesting under BIPRU 7.10.111R, although carried out with respect to each business day, need not be carried out each day. A firm need only carry it out sufficiently frequently to comply with its reporting requirements under BIPRU 7.10.129R. An exception arising out of such backtesting need not be reported to the FSA under BIPRU 7.10.104R
  3. (3) The firm may also need to calculate a clean hypothetical profit and loss figure in order to produce profit attribution reports and to analyse the cause of backtesting exceptions.
  • 01/01/2007

The model PRR is, for any business day (the "relevant" business day), calculated in accordance with the following formula:

  1. (1) the higher of:
    1. (a) the VaR number for the relevant business day; and
    2. (b) the average of its daily VaR numbers for each of the 60 business days ending with the relevant business day, multiplied by the multiplication factor for the relevant business day; and
  2. (2) (in the case of a VaR model permission that covers specific risk) the incremental default risk charge for the relevant business day.
  • 01/01/2007

The VaR number for any business day means the VaR measure, in respect of the previous business day's close-of-business positions in products coming within the scope of the VaR model permission, calculated by the VaR model and in accordance with BIPRU 7.10 and any methodology set out in the VaR model permission. The VaR number must not be calculated taking into account matters on the business day for which it is the VaR number.
  • 01/01/2007

BIPRU 7.10.116

where:

  1. (1) PRR Var is a firm's model PRR;
  2. (2) VaR t represents the previous day's value-at-risk figure;
  3. (3) VaR t-i represents the value-at-risk calculated for i business days earlier;
  4. (4) f is the multiplication factor; and
  5. (5) IDRC is the incremental default risk charge (if applicable).

The minimum multiplication factor is three or any higher amount the VaR model permission defines it as.
  • 01/01/2007

BIPRU 7.10.120

handbook-guidance
The minimum multiplication factor will never be less than three. If the FSA does set the minimum multiplication factor above three the VaR model permission will have a table that sets outs the reasons for that add on and specify how much of the add on is attributable to each reason (see BIPRU 7.10.121R). If there are weaknesses in the VaR model that may otherwise be considered a breach of the minimum standards referred to in BIPRU 7.10.24R the FSA may apply such an add on to act as a mitigant for those weaknesses.
  • 01/01/2007

BIPRU 7.10.121

handbook-rule
Something that would otherwise be a breach of the minimum standards to in BIPRU 7.10.26R - BIPRU 7.10.53R is not a breach to the extent that that thing is identified in the firm's VaR permission as a reason for an increase in the minimum multiplication factor above 3.
  • 01/01/2007

BIPRU 7.10.122

handbook-guidance
Typically, any add on will be due to a specific weakness in systems and controls identified during the FSA's review that the FSA does not consider material enough to justify withholding overall model recognition. The firm will be expected to take action to address the reasons for any add on. The FSA will then review these periodically and, where satisfactory action has been taken, the add on will be removed through a variation of the VaR model permission.
  • 01/01/2007

BIPRU 7.10.123

handbook-guidance
The plus factor system is designed so that the more often a VaR model has under-predicted losses in the past, the higher should be the capital requirement based on the VaR model. It is intended to provide a capital incentive for the firm to continue to improve the accuracy of its VaR model.
  • 01/01/2007

BIPRU 7.10.124

handbook-rule
The table in BIPRU 7.10.125R sets out the plus factors to be added to the minimum multiplication factor for any business day. It is based on the number of backtesting exceptions that occurred during the backtesting period as referred to in BIPRU 7.10.96R (Backtesting: Basic testing requirements) ending three business days preceding the business day for which the model PRR is being calculated.

Table: Backtesting plus factors
This table belongs to BIPRU 7.10.124R
  • 01/01/2007

BIPRU 7.10.126

handbook-guidance
A VaR model that correctly predicts a one-tailed 99% confidence level is expected to produce, on average, 2.5 backtesting exceptions every 250 days. Random events may cause the number of backtesting exceptions actually observed to vary. The plus factor system is designed to take this into account. Hence plus factors are only imposed on the firm if it has five or more recorded backtesting exceptions. Therefore, where a backtesting exception appears to be caused simply by chance, it will not be appropriate for a VaR model permission to be varied to exclude that backtesting exception as described in BIPRU 7.10.106G (Backtesting: Process for disregarding backtesting exceptions).

Capital calculations: Specific risk surcharge: transitional requirements

BIPRU 7.10.127

handbook-guidance
Firms who gained model recognition before 1 January 2007 will be permitted to calculate PRR for specific risk in accordance with the methodology they were permitted to use immediately before that date instead of capturing event and default risk in their models (see BIPRU TP 14 (Market risk: VaR models)). This treatment will not be available to a firm that gains model recognition after that date.

A firm must, no later than the number of business days after the end of each quarter specified in the VaR model permission for this purpose, submit, in respect of that quarter, a report to the FSA about the operation of the VaR model, the systems and controls relating to it and any changes to the VaR model and those systems and controls. Each report must outline as a minimum the following information in respect of that quarter:

  1. (1) methodological changes and developments to the VaR model;
  2. (2) the introduction of all new pricing models used in connection with the VaR model and any changes to any pricing models used in connection with the VaR model, including details of any material associated valuation or risk management issues;
  3. (3) a summary of backtesting performance against clean profit and loss figures and clean hypothetical profit and loss figures, which must be provided in electronic format as stipulated by the VaR model permission;

The information in BIPRU 7.10.131G will vary over time. It is therefore not included in a VaR model permission as a rule but for information only. The FSA will update that information regularly in accordance with information supplied under BIPRU 7.10.129R. That updating will not amount to a variation of the VaR model permission.

Link to standard PRR rules: Incorporation of the model output into the capital calculation

BIPRU 7.10.133

handbook-guidance
A VaR model permission will modify GENPRU 2.1.52 R (Calculation of the market risk capital requirement) to provide that a firm should calculate its market risk capital requirement in accordance with BIPRU 7.10 to the extent set out in the VaR model permission.
  • 01/01/2007

BIPRU 7.10.134

handbook-guidance
By modifying GENPRU 2.1.52 R (Calculation of the market risk capital requirement) to allow the firm to use the VaR model to calculate all or part of its PRR for certain positions, the FSA is treating it like an application rule. The modification means that the PRR calculation set out in BIPRU 7.10 supersedes the standard market risk PRR rules for products and risks coming within the scope of the VaR model permission.
  • 01/01/2007

BIPRU 7.10.135

handbook-rule
To the extent that a position does not fall within the scope of a firm's VaR model permission the firm must calculate the PRR under the standard market risk PRR rules or, as applicable, those provisions as modified by the firm's CAD 1 waiver.
  • 01/01/2007

BIPRU 7.10.136

handbook-rule
  1. (1) This rule applies to a position of a type that comes within the scope of a firm's VaR model permission.
  2. (2) If, where the standard market risk PRR rules apply, a position is subject to a PRR charge and the firm's VaR model permission says that it covers the risks to which that PRR charge relates, the firm must, for those risks, calculate the PRR for that position under the VaR model approach rather than under the standard market risk PRR rules.
  3. (3) If, where the standard market risk PRR rules apply, a position is subject to one or more PRR charges and the firm's VaR model permission does not cover all the risks to which those PRR charges relate, the firm must calculate the PRR for that position under the VaR model approach (for those risks that are covered) and under the standard market risk PRR rules (for those other risks).
  4. (4) Where the standard market risk PRR rules distinguish between specific risk and general market risk a firm's VaR model permission covers specific risk to the extent that it says it does. If the firm's VaR model permission does not cover specific risk, BIPRU 7.10.143R and BIPRU 7.10.144R apply.
  5. (5) If a firm's VaR model permission covers positions in CIUs it covers specific risk with respect to those positions.
  • 01/01/2007

BIPRU 7.10.137

BIPRU 7.10.138

handbook-rule
  1. (1) If a firm calculates its market risk capital requirement using a combination of the standard market risk PRR rules and either the VaR model approach or the VaR model approach with the CAD 1 model approach the PRR from each method must be added together.
  2. (2) A firm must take appropriate steps to ensure that all of the approaches are applied in a consistent manner.
  • 01/01/2007

BIPRU 7.10.139

handbook-guidance
An example of the effect of BIPRU 7.10.138R is that where a firm normally calculates the PRR for a particular portfolio using a VaR model, a firm should not switch to the standard market risk PRR rules purely to achieve a more attractive PRR.
  • 01/01/2007

If:

  1. (1) the standard market risk PRR rules provide for a choice of which of the PRR charges to use or specify that one type must be used in some circumstances and that another type must be used in other circumstances;
  2. (2) one of those types is disapplied under BIPRU 7.10.136R; and
  3. (3) the other type is not disapplied;
the firm:
  1. (4) must use the VaR model approach if under the standard market risk PRR rules the firm must use the standard market risk PRR rules in (2); and
  2. (5) may use the VaR model approach if under the standard market risk PRR rules the firm may use the standard market risk PRR rules in (2).
  • 01/01/2007

BIPRU 7.10.141

handbook-guidance
The treatment of a convertible is an example of a situation in which BIPRU 7.10.140R applies. The table in BIPRU 7.3.3R (Table: Instruments which result in notional positions) shows that there are circumstances in which under the standard market risk PRR rules a firm should calculate an equity PRR and that there are circumstances in which a firm may choose between calculating an equity PRR and an interest rate PRR. BIPRU 7.10.140R would be relevant if a firm's VaR model permission only covers one of equity risk and interest rate risk.
  • 01/01/2007

BIPRU 7.10.142

  1. (1) To the extent that a firm's VaR model permission does not allow it to use an approach set out in BIPRU 7.10 the relevant provisions in BIPRU 7.10 do not apply to that firm.
  2. (2) If a provision of the Handbook refers to BIPRU 7.10, that reference must, in the case of a particular firm with a VaR model permission, be treated as excluding provisions of BIPRU 7.10 that do not apply under the VaR model permission and as taking into account any modifications to BIPRU 7.10 made by the VaR model permission. Such references also include requirements and conditions contained in the VaR model permission but not BIPRU 7.10 and to the rules modified by the VaR model permission.

Ceasing to meet the requirements of BIPRU 7.10

BIPRU 7.10.147

handbook-guidance
If a firm ceases to meet any of the requirements set out in BIPRU 7.10, the FSA's policy is that the VaR model permission should cease to have effect. In part this will be achieved by making it a condition of a firm's VaR model permission that it complies at all times with the minimum standards referred to in BIPRU 7.10.26R - BIPRU 7.10.53R. Even if they are not formally included as conditions, the FSA is likely to consider revoking the VaR model permission if the requirements are not met.
  • 01/01/2007

BIPRU 7.10.148

If a firm ceases to meet the conditions or requirements in its VaR model permission or BIPRU 7.10 it must notify the FSA at once.

Changes to a VaR model

BIPRU 7.10.149

handbook-rule

A firm may change its VaR model to such extent as it sees fit, except that it must not make a change that (either on its own or together with other changes since the date of VaR model permission) would:

  1. (1) be inconsistent with VaR model permission or BIPRU 7.10; or
  2. (2) mean that backtesting in accordance with BIPRU 7.10 and the VaR model permission would result in the use of data that is inappropriate for the purposes of measuring the performance of the VaR model.

Establishment of positions created by credit derivatives: Treatment of the protection seller

BIPRU 7.11.2

handbook-rule
BIPRU 7.11.3R - BIPRU 7.11.11R relate to the treatment of the protection seller for the purpose of calculating the securities PRR. Positions are determined in accordance with BIPRU 7.11.4R - BIPRU 7.11.11R.
  • 01/01/2007

BIPRU 7.11.3

handbook-rule
When calculating the PRR of the protection seller, unless specified differently by other rules, the notional amount of the credit derivative contract must be used. For the purpose of calculating the specific risk PRR charge, other than for total return swaps, the maturity of the credit derivative contract is applicable instead of the maturity of the obligation.
  • 01/01/2007

BIPRU 7.11.4

handbook-rule
A total return swap creates a long position in the general market risk of the reference obligation and a short position in the general market risk of a zero-specific-risk security with a maturity equivalent to the period until the next interest fixing and which is assigned a 0% risk weight under the standardised approach to credit risk. It also creates a long position in the specific risk of the reference obligation.
  • 01/01/2007

BIPRU 7.11.5

handbook-rule
A credit default swap does not create a position for general market risk. For the purposes of specific risk, a firm must record a synthetic long position in an obligation of the reference entity, unless the derivative is rated externally and meets the conditions for a qualifying debt security, in which case a long position in the derivative is recorded. If premium or interest payments are due under the product, these cash flows must be represented as notional positions in zero-specific-risk securities.
  • 01/01/2007

BIPRU 7.11.6

handbook-rule
A single name credit linked note creates a long position in the general market risk of the note itself, as an interest rate product. For the purpose of specific risk, a synthetic long position is created in an obligation of the reference entity. An additional long position is created in the issuer of the note. Where the credit linked note has an external rating and meets the conditions for a qualifying debt security, a single long position with the specific risk of the note need only be recorded.
  • 01/01/2007

BIPRU 7.11.7

handbook-rule
In addition to a long position in the specific risk of the issuer of the note, a multiple name credit linked note providing proportional protection creates a position in each reference entity, with the total notional amount of the contract assigned across the positions according to the proportion of the total notional amount that each exposure to a reference entity represents. Where more than one obligation of a reference entity can be selected, the obligation with the highest risk weighting determines the specific risk.
  • 01/01/2007

BIPRU 7.11.8

handbook-rule
Where a multiple name credit linked note has an external rating and meets the conditions for a qualifying debt security, a single long position with the specific risk of the note need only be recorded.
  • 01/01/2007

BIPRU 7.11.9

handbook-rule
A first-asset-to-default credit derivative creates a position for the notional amount in an obligation of each reference entity. If the size of the maximum credit event payment is lower than the PRR requirement under the method in the first sentence of this rule, the maximum payment amount may be taken as the PRR requirement for specific risk.
  • 01/01/2007

BIPRU 7.11.10

handbook-rule
A second-asset-to-default credit derivative creates a position for the notional amount in an obligation of each reference entity less one (that with the lowest specific risk PRR requirement). If the size of the maximum credit event payment is lower than the PRR requirement under the method in the first sentence of this rule, this amount may be taken as the PRR requirement for specific risk.
  • 01/01/2007

BIPRU 7.11.11

handbook-rule
If a first or second-asset to default derivative is externally rated and meets the conditions for a qualifying debt security, then the protection seller need only calculate one specific risk charge reflecting the rating of the derivative.

Establishment of positions created by credit derivatives: Treatment of the protection buyer

BIPRU 7.11.12

handbook-rule

For the protection buyer, the positions are determined as the mirror principle of the protection seller, with the exception of a credit linked note (which entails no short position in the issuer). If at a given moment there is a call option in combination with a step-up, such moment is treated as the maturity of the protection. In the case of first-to-default credit derivatives and nth to default credit derivatives, the treatment in BIPRU 7.11.12AR and BIPRU 7.11.12B R applies instead of the mirror principle.

[Note: CAD Annex I point 8.B]

  • 31/12/2010

BIPRU 7.11.12A

handbook-rule

Where a firm obtains credit protection for a number of reference entities underlying a credit derivative under the terms that the first default among the assets will trigger payment and that this credit event will terminate the contract, the firm may off-set specific risk for the reference entity to which the lowest specific risk percentage charge among the underlying reference entities applies according to the Table in BIPRU 7.2.44R.

[Note: CAD Annex I point 8.B]

  • 31/12/2010

BIPRU 7.11.12B

handbook-rule

Where the nth default among the exposures triggers payment under the credit protection, the protection buyer may only off-set specific risk if protection has also been obtained for defaults 1 to n-1 or when n-1 defaults have already occurred. In those cases, the methodology set out in BIPRU 7.11.12AR for first-to-default credit derivatives must be followed, appropriately modified for nth-to-default products.

  2. (2) This will be the case in the following situations:
    1. (a) the two legs consist of completely identical instruments; or
    2. (b) a long cash position is hedged by a total rate of return swap (or vice versa) and there is an exact match between the reference obligation and the underlying exposure (i.e., the cash position).
  3. (3) The maturity of the swap itself may be different from that of the underlying exposure for the purposes of (2)(b).
  4. (4) In these situations, a firm must not apply a specific risk PRR to either side of the position.
  • 01/01/2007

BIPRU 7.11.15

handbook-rule
An 80% offset may be applied when the value of two legs always move in the opposite direction and where there is an exact match in terms of the reference obligation, the maturity of both the reference obligation and the credit derivative, and the currency of the underlying exposure. In addition, key features of the credit derivative contract must not cause the price movement of the credit derivative materially to deviate from the price movements of the cash position. To the extent that the transaction transfers risk, an 80% specific risk offset may be applied to the side of the transaction with the higher PRR, while the specific risk requirements on the other side are zero.
  • 01/01/2007

BIPRU 7.11.16

handbook-rule
  1. (1) A firm may take partial allowance when the value of two legs usually move in the opposite direction. This would be the case in the situations set out in (2) - (4).
  2. (2) The first situation referred to in (1) is that the position falls under BIPRU 7.11.16 R (2)(b) but there is an asset mismatch between the reference obligation and the underlying exposure. However, the positions meet the following requirements:
    1. (a) the reference obligation ranks pari passu with or is junior to the underlying obligation; and
    2. (b) the underlying obligation and reference obligation share the same obligor and have legally enforceable cross-default or cross-acceleration clauses.
  3. (3) The second situation referred to in (1) is that the position falls under BIPRU 7.11.14 R (2)(a) or BIPRU 7.11.15 R but there is a currency or maturity mismatch between the credit protection and the underlying asset (currency mismatches must be included in the normal reporting with respect to the foreign currency PRR).
  4. (4) The third situation referred to in (1) is that the position falls under BIPRU 7.11.15 R but there is an asset mismatch between the cash position and the credit derivative. However, the underlying asset is included in the (deliverable) obligations in the credit derivative documentation.
  5. (5) In each of those situations, rather than adding the specific risk PRR requirements for each side of the transaction, only the higher of the two PRR requirements applies.

Valuation changes for credit default swaps resulting in positions in multiple securities

BIPRU 7.11.35

handbook-rule
  1. (1) This rule applies if BIPRU 7.11.24 R results in a credit default swap being split into positions in more than one security.
  2. (2) The firm must, for each notional security produced as described in (1), apply to the whole of the credit default swap in question the stresses in the table in BIPRU 7.11.34 R using the credit quality step in the table in BIPRU 7.11.34 R for that security.
  3. (3) The firm must then allocate the different changes in the value of the credit default swap under (2) between the calculations for each security produced as described in (1) on a proportional basis in accordance with the principles in BIPRU 7.11.2 R - BIPRU 7.11.12 R. The firm must do this by multiplying the amount of the change in (2) calculated with respect to the security in question by a fraction based on the proportion of the credit default swap attributable to the security under those principles.

Ordinary credit default swap PRR method: The default capital charge

BIPRU 7.11.36

handbook-rule
The default capital charge for each group of credit default swaps created under BIPRU 7.11.24 R is equal to two multiplied by the amount in BIPRU 7.11.37 R. The total default capital charge for credit default swaps treated under the ordinary credit default swap PRR method is equal to the sum of such amounts for each such group.
  • 01/01/2009

BIPRU 7.11.37

handbook-rule
  1. (1) The amount calculated under this rule is the amount resulting from the calculation in (5).
  2. (2) A firm must fully net all notional positions along a timeline by calculating, for all credit default swaps in the group in question created under BIPRU 7.11.24 R, the net positions in the security in question for all times in the future until those positions expire or otherwise cease to exist.
  3. (3) The firm must calculate the net positions under (2) in accordance with BIPRU 7.2.37 R - BIPRU 7.2.40 R (Deriving the net position in each debt security: Netting positions in the same debt security).
  4. (4) The firm must identify the largest long position to which it is exposed over the next year.
  5. (5) The firm must then multiply the amount established under (4) by the appropriate PRA that would have applied for the purpose of calculating the specific risk portion of the interest rate PRR under BIPRU 7.2 (Interest rate PRR).
  6. (6) The security in question is the one by reference to which the grouping under BIPRU 7.11.24 R is carried out (the reference entity).

Securitisation credit default swap PRR method: Main rule for calculating the specific risk PRR

BIPRU 7.11.39

handbook-rule

The specific risk portion of the interest rate PRR for credit default swaps treated under the securitisation credit default swap PRR method is the higher of:

  1. (1) an amount equal to what would have been the specific risk portion of the interest rate PRR for such credit default swaps if it had been calculated under of BIPRU 7.2.43 R to BIPRU 7.2.50 R (Specific risk calculation for interest rate risk), taking into account BIPRU 7.11.19 R and BIPRU 7.11.21 R; and
  2. (2) the sum of the valuation change capital charge (see BIPRU 7.11.40 R) and the default capital charge (see BIPRU 7.11.48 R) for all such credit derivatives.

Securitisation credit default swap PRR method: Valuation change capital charge: General

BIPRU 7.11.40

handbook-rule
In order to calculate the valuation change capital charge a firm must group together each credit default swap that relates to the same securitisation. The valuation change capital charge for each such group is equal to three multiplied by the potential loss amount in BIPRU 7.11.41 R. The total valuation change capital charge for credit default swaps treated under the securitisation credit default swap PRR method is equal to the sum of such amounts for each such group.
  • 01/01/2009

BIPRU 7.11.41

handbook-rule
  1. (1) The potential loss amount as referred to in BIPRU 7.11.40 R for a group of credit default swaps relating to the same securitisation is equal to the greatest loss the firm would suffer in the scenarios set out in the matrix in BIPRU 7.11.43 R. Each scenario consists of the combination of one of the nine scenarios on the vertical axis with one of the three scenarios on the horizontal axis.
  2. (2) T as referred to in that matrix is the amount set out in the table in BIPRU 7.11.44 R.
  3. (3) Stresses (1) - (4) as referred to in that matrix are further defined in BIPRU 7.11.45 R - BIPRU 7.11.46 R.
  4. (4) The underlying reference entities referred to in that matrix refer to the obligor under the securities that are the subject of the securitisation in question. In the case of a resecuritisation the reference entities are the ultimate underling obligors (the obligors under the securitised securitisation).
  5. (5) The valuation change under this rule is applied to the current value of the credit default swap.

handbook-rule
References in the table in BIPRU 7.11.43 R to credit quality steps are to the credit quality steps that would apply under the standardised approach to credit risk to the securities referred to in BIPRU 7.11.41 R (4). If a rating from an eligible ECAI is not available to the firm it must treat that security as having the lowest credit quality step.

Securitisation credit default swap PRR method: Valuation change capital charge: Base correlation

BIPRU 7.11.45

handbook-rule
  1. (1) This rule explains how the correlation calculations in the vertical axis of the matrix in BIPRU 7.11.43 R are to be carried out.
  2. (2) The firm must calculate the base correlation relating to each of the deemed tranches set out in the table in BIPRU 7.11.46 R. Base correlation refers, in relation to a securitisation position, to the correlation in credit risk between the securities that are the subject of that securitisation.
  3. (3) The firm must then multiply the base correlation for each deemed tranche under (2) by the relevant figure in the table in BIPRU 7.11.46 R. It must calculate each such base correlation in the way that a person would use to calculate the fair market value of a credit default swap on the following basis:
    1. (a) the tranche is the most junior tranche; and
    2. (b) the thickness of the tranche (as referred to in BIPRU 9 (Securitisation)) is equal to the percentage figure at the head of the relevant column in the table in BIPRU 7.11.46 R.
  4. (4) The firm must then produce a stressed base correlation curve through the use of interpolation based on the calculations under this rule.
  5. (5) Notwithstanding (3), the curve in (4) must not show a correlation above 100%.
  6. (6) The firm must then use the curve for the purpose of the revaluation of the credit default swap under BIPRU 7.11.41 R using an appropriate and prudent technique.

BIPRU 7.11.47

handbook-guidance
The fact that the FSA has used the base correlation methodology in this section does not mean that it endorses the use of that technique to value credit default swaps for other purposes. The FSA has used it in this section as it is well-known and publicly available. If a firm uses another technique to value its credit default swaps it should discuss this with the FSA.

Securitisation credit default swap PRR method: Default charge

BIPRU 7.11.48

handbook-rule
The default charge for a firm's position in a securitisation treated under the securitisation credit default swap PRR method is equal to the default charge for that position calculated under BIPRU 7.11.50 R and BIPRU 7.11.51 R. The total default charge for positions treated under the securitisation credit default swap PRR method is equal to the sum of those figures.
  • 01/01/2007

BIPRU 7.11.49

handbook-rule
If a position is short, the default charge for that position is zero.
  • 01/01/2007

BIPRU 7.11.51

handbook-rule

If a position is long, the default charge for that position must be calculated in accordance with the following formula:
V x RW x AP
where:

  1. (1) V means the notional amount of the position;
  2. (2) RW means the risk weight that the position would attract under BIPRU 9 (Securitisation); and
  3. (3) AP means the appropriate percentage from the table BIPRU 7.11.52 R.

  1. (1) The column of the table in BIPRU 7.11.52 R headed "Trades based on an index" applies if:
    1. (a) the position is not a resecuritisation position;
    2. (b) the underlying reference entities (as defined in BIPRU 7.11.41 R (4)) are identical to those that make up an index of entities widely used by those who deal in credit default swaps;
    3. (c) that index contains the price for entering into a credit default swap whose reference entities constitute all the entities in the index; and
    4. (d) the credit default swap is constructed in such a way that the firm is able to price the credit derivative using the index.
  2. (2) The column of the table in BIPRU 7.11.52 R headed "Other" applies to any case not covered by the other two categories in the table.

The spread referred to in the tables in BIPRU 7.11.34 R and BIPRU 7.11.43 R refers to the premia and other cash flows referred to in BIPRU 7.11.5 R (expressed as a percentage). The spread must be calculated every business day. It is the spread that would apply if the credit default swap in question were entered into on that day on arm's length commercial terms.
  • 01/01/2007

BIPRU 7.11.56

handbook-rule
Where a credit default swap PRR method requires netting between positions, a firm may only net positions arising out of credit default swaps that have comparable deliverable obligations, identical credit events and documentation that will act identically on the occurrence of a credit event.
  • 01/01/2007

BIPRU 7.11.57

handbook-rule
A notional position in a zero-specific-risk security created under BIPRU 7.11.5 R must not be treated under either credit default swap PRR method. The firm must instead treat it in accordance with the other rules for the calculation of the interest rate PRR.
  • 01/01/2007

BIPRU 7.11.58

handbook-rule
  1. (1) If the size of the maximum credit event payment under a credit default swap is lower than the PRR requirement that would otherwise apply, that credit default swap must be excluded from the credit default swap PRR methods. However BIPRU 7.11.19 R and BIPRU 7.11.21 R still apply.
  2. (2) A firm must work out whether (1) applies to a credit default swap by calculating the PRR for that credit default swap in accordance with this section (including the applicable credit default swap PRR method) on the assumption that it is the only item for which an interest rate PRR is being calculated.

BIPRU 7.11.62 G - BIPRU 7.11.64 G G cover risks relating to credit derivatives that may not be captured in this section. This guidance is of particular relevance to the overall financial adequacy rule, the overall Pillar 2 rule and the general stress and scenario testing rule.
  • 01/01/2007

BIPRU 7.11.62

handbook-guidance
BIPRU 7.11.5 R requires a firm to recognise any premiums payable or receivable under the contract as notional zero-specific-risk securities. These positions are then entered into the general market risk framework. As premium payments paid under such contracts are contingent on no credit event occurring, a credit event could significantly change the general market risk capital requirement. A firm should consider, under the overall Pillar 2 rule, whether this risk means that the capital requirements under this section materially understate the firm's general market risk position.
  • 01/01/2007

BIPRU 7.11.63

handbook-guidance
If a firm recognises profits on a non-accrual basis it should consider whether the capital requirements for its credit derivatives business adequately cover the risk that any recognised profit may not be achieved due to a credit event occurring. This includes positions for which the firm may have a perfect hedge in place.
  • 01/01/2007

BIPRU 7.11.64

handbook-guidance
If a firm uses models in its valuation process, it should consider whether the default capital requirements under the credit default swap PRR methods adequately cover the default losses that the firm's model estimates it will be exposed to.
