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 7.10.39RRP
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 7.10.136RRP
(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 7.10.136ARRP
3A firm must calculate the market risk capital requirement for securitisation positions and positions in the correlation trading portfolio in accordance with the standard market risk PRR rules, with the exception of those positions subject to the all price risk measure.
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 7.10.143RRP
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.
BIPRU 7.9.1GRP
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 appropriate regulator 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.

The output and how it is used in the PRR calculation

Depending on the type of model and the requirements in the CAD 1 model waiver granted, the outputs from an options risk aggregation model are used as an input to the market risk capital requirement calculation.

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).
