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
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'sVaR 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.
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) the adequacy of the documentation of the risk management system and process;(2) the organisation
(1) This rule applies to a position of a type that comes within the scope of a firm'sVaR model permission.(2) Subject to BIPRU 7.10.136A R, if, 3where the standard market risk PRR rules apply, a position is subject to a PRR charge and the firm'sVaR 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)
(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) A firm must take appropriate steps to ensure that all of the approaches are applied in a consistent manner.
If a firm'sVaR model permission covers interest rate general market risk but not interest rate specific risk, the firm must calculate the interest rate PRR so far as it relates to interest rate specific risk in accordance with the standard market risk PRR rules except that the firm must not use the basic interest rate PRR calculation in BIPRU 7.3.45R (Basic interest rate calculation for equity instruments).
If a firm'sVaR model permission covers equitygeneral market risk but not equityspecific risk, the firm must calculate the equity PRR so far as it relates to equityspecific risk in accordance with the standard market risk PRR rules except that the PRR for equityspecific risk must be calculated under the standard equity method.
(1) A firm must calculate its interest rate PRR under BIPRU 7.2 by:(a) identifying which positions must be included within the interest rate PRR calculation;(b) deriving the net position in each debt security in accordance with BIPRU 7.2.36R-BIPRU 7.2.41R;(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(d) summing all PRRs calculated for general market risk and specific risk.(2)
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.
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
Under the interest rate maturity method, the portion of the interest rate PRR for general market risk is calculated as follows:(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) Step 2: weighted long and short positions are matched within:(a) the same maturity band;(b) the same zone (using unmatched positions from (a)); and(c) different zones (using unmatched positions from (b) and
Under the interest rate duration method, the portion of the interest rate PRR for general market risk is calculated as follows:(1) Step 1: allocate each net position to the appropriate duration zone in the table in BIPRU 7.2.65R and multiply it by:(a) its modified duration (using the formula in BIPRU 7.2.63R); and(b) the appropriate assumed interest rate change in the table in BIPRU 7.2.65R;(2) Step 2: match weighted long and short positions:(a) within zones; and(b) across zones

(1) A firm must calculate its equity PRR by:(a) identifying which positions must be included within the PRR calculation (see BIPRU 7.3.2R);(b) deriving the net position in each equity in accordance with BIPRU 7.3.23R;(c) including each of those net positions in either the simplified equity method (see BIPRU 7.3.29R) or, subject to BIPRU 7.3.27R, the standard equity method (see BIPRU 7.3.32R); and(d) summing the PRR on each net position as calculated under the simplified equity
Under the standard equity method, a firm must:(1) group equitypositions into country portfolios as follows:(a) a position in an individual equity belongs to:(i) the country it is listed in;(ii) any of the countries it is listed in, if more than one; or(iii) the country it was issued from, if unlisted;(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
(1) Under approach two as referred to in BIPRU 7.3.40R, the PRR for general market risk is calculated using the following formula:(2) In the formula in (1) CPi denotes the net value of ith country portfolio (converted to the firm'sbase currency using current spot foreign currency rates).(3) The conditions referred to in BIPRU 7.3.40R that must be met for a firm to be able to use approach two as referred to in BIPRU 7.3.40R are as follows:(a) at least four country portfolios are
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 equityposition separately and then summed without offsetting long and short positions.
This rule applies to a firm that does not include a forward, future, option or swap on an equity, basket of equities or equity index in the calculation of its interest rate PRR calculation under BIPRU 7.2 (Interest rate PRR). 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:(1) multiply the market value
Cliquets on equities, baskets of equities or equity indices do not attract an interest rate PRR. BIPRU 7.3.45R excludes them from the basic interest rate PRR calculation and the table in BIPRU 7.2.4R (Table: Instruments which result in notional positions) excludes them from the scope of the interest rate PRR calculation in BIPRU 7.2 (Interest rate PRR).
A firm may treat (for the purpose of calculating an option PRR under BIPRU 7.6) an option strategy listed in the table in BIPRU 7.6.15R as the single position in a notional option specified against that strategy in the table in BIPRU 7.6.15R, if:(1) each element of the strategy is transacted with the same counterparty;(2) the strategy is documented as a single structure;(3) the underlying for each part of the composite position (including any actual holding of the underlying)
A firm may rely on a third party to calculate and report PRR capital requirements for position risk (general market risk and specific risk) for positions in CIUs falling within BIPRU 7.7.9R and BIPRU 7.7.11R, in accordance with the methods set out in BIPRU 7.7, provided that the correctness of the calculation and the report is adequately ensured.
Without prejudice to other provisions in BIPRU 7.7, a position in a CIU is subject to a collective investment undertaking PRR (general market risk and specific risk) of 32%. Without prejudice to provisions in BIPRU 7.5.18R (Foreign currency PRR for CIUs) or, if the firm has a VaR model permission, BIPRU 7.10.44R (Commodity risks and VaR models) taken together with BIPRU 7.5.18R, where the modified gold treatment set out in those rules is used, a position in a CIU is subject to
(1) Where a firm is aware of the underlying investments of the CIU on a daily basis the firm may look through to those underlying investments in order to calculate the securities PRR for position risk (general market risk and specific risk) for those positions in accordance with the methods set out in the securities PRR requirements or, if the firm has a VaR model permission, in accordance with the methods set out in BIPRU 7.10 (Use of a Value at Risk Model).(2) Under this approach,
(1) A firm may calculate the securities PRR for position risk (general market risk and specific risk) for positions in CIUs in accordance with the methods set out in the securities PRR requirements or, if the firm has a VaR model permission, in accordance with the methods set out in BIPRU 7.10 (Use of a Value at Risk Model), to assumed positions representing those necessary to replicate the composition and performance of the externally generated index or fixed basket of equities
Where a firm is not aware of the underlying investments of the CIU on a daily basis, the firm may calculate the securities PRR for position risk (general market risk and specific risk) in accordance with the methods set out in the securities PRR requirements, subject to the following conditions:(1) it must be assumed that the CIU first invests to the maximum extent allowed under its mandate in the asset classes attracting the highest securities PRR for position risk (general market
(1) If a firm has a position:(a) in a PRR item in non-standard form; or(b) that is part of a non-standard arrangement; or(c) that, taken together with other positions (whether or not they are subject to PRRcharges under BIPRU 7), gives rise to a non-standard market risk;the firm must notify the FSA of that fact and of details about the position, PRR item, arrangements and type of risk concerned.(2) Except as (1) provides to the contrary, (1) applies to a position that is subject
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.
The interest-rate and foreign-exchange risks not covered by other provisions of BIPRU 7.4 or by the provisions of BIPRU 7.2 (Interest rate PRR) or BIPRU 7.5 (Foreign currency PRR) must be included in the calculation of general market risk for traded debt securities and in the calculation of foreign currency PRR.
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.

Depending on the type of model and the requirements in the CAD 1 model waiver granted, the individual sensitivity figures produced by this type of CAD 1 model are either input into the calculation of interest rate PRR under the interest rate duration method (see BIPRU 7.2.63R) or are converted into notional position and input into the calculation of interest rate PRR under the interest rate maturity method (see BIPRU 7.2.59R). |
To calculate the reduced net underwriting position a firm must apply the reduction factors in the table in BIPRU 7.8.28R to the net underwriting position (calculated under BIPRU 7.8.17R) as follows:(1) in respect of debt securities, a firm must calculate two reduced net underwriting positions; one for inclusion in the firm'sinterest rate PRRspecific risk calculation (BIPRU 7.2.43R), the other for inclusion in its interest rate PRRgeneral market risk calculation (BIPRU 7.2.52R);
Where a firm is exposed to market risk, the6 time horizon over which stress tests and scenario analyses 6should be carried out will 6depend on, among other things,6 the maturity and liquidity of the positions stressed. For example, for the market risk arising from the holding of investments, this will 6depend upon:6666(1) the extent to which there is a regular, open and transparent market in those assets, which would allow fluctuations in the value of the investment to be more
