BIPRU 7.10.2GRP
BIPRU 7.10 provides details of when the appropriate regulator 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
BIPRU 7.10.3GRP
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 appropriate regulator, are based on and implement
BIPRU 7.10.4GRP
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
BIPRU 7.10.6GRP
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.
BIPRU 7.10.7GRP
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 appropriate regulator 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
BIPRU 7.10.39RRP
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.
BIPRU 7.10.134GRP
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 appropriate regulator 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.
BIPRU 7.10.136RRP
(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)
BIPRU 7.10.138RRP
(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.
BIPRU 7.10.139GRP
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.
BIPRU 7.10.140RRP
If:(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) one of those types is disapplied under BIPRU 7.10.136R; and(3) the other type is not disapplied;the firm:(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(5) may use
BIPRU 7.10.141GRP
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'sVaR model permission
BIPRU 7.10.142RRP
The standard market risk PRR rules for the option PRR are only disapplied to the extent that the derived positions arising under BIPRU 7.6.13R (Table: Derived positions) come within the scope of the VaR model permission.
BIPRU 7.10.143RRP
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).
BIPRU 7.10.144RRP
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.
