BIPRU 7.10.38GRP
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
BIPRU 7.10.46RRP
(1) If a firm'sVaR 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) The VaR model must explain the historical price variation in the portfolios concerned.(3) The VaR model must capture concentration in terms of magnitude and changes of composition of the portfolios concerned.(4) The VaR model must be robust to an adverse environment.(5) The VaR
BIPRU 7.10.47GRP
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
BIPRU 7.10.48RRP
(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) A firm'sVaR model must conservatively assess the risk arising from less liquid positions and positions with limited price transparency under realistic market scenarios.
BIPRU 7.10.72RRP
(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) The programme must particularly address:(a) concentration risk;(b) illiquidity of markets in stressed market conditions;(c) one way markets;(d) event and jump to default risks;(e) non linearity of products;(f) deep out of the money positions;(g) positions subject to the gapping of
BIPRU 7.10.78RRP
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
BIPRU 7.10.79GRP
(1) In addition to regulatory backtesting programs, testing for model validation should be carried out using additional tests which may include for example:(a) testing carried out using hypothetical changes in portfolio value that would occur were end of day positions to remain unchanged;(b) testing carried out for longer periods than required for the regular backtesting programme (for example, 3 years);(c) testing carried out using confidence intervals other than the 99 percent
BIPRU 7.10.91GRP
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'sVaR model and to provide incentives for firms to improve their VaR measures.
BIPRU 7.10.93GRP
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'splus 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
BIPRU 7.10.107RRP
If a firm'sVaR 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.
BIPRU 7.10.108GRP
Specific risk backtesting involves the backtesting of a standalone specific riskVaR 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'sVaR
BIPRU 7.10.111RRP
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.
BIPRU 7.10.129RRP
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) methodological changes and developments to the
BIPRU 7.10.146RRP
A VaR model must be a value-at-risk model. It must provide an estimate of the worst expected loss on a portfolio resulting from market movements over a period of time with the specified confidence level.
