§ 324.206 Stressed VaR-based measure.

(a) General requirement. At least weekly, an FDIC-supervised institution must use the same internal model(s) used to calculate its VaR-based measure to calculate a stressed VaR-based measure. (b) Quantitative requirements for stressed VaR-based measure. (1) An FDIC-supervised institution must calculate a stressed VaR-based measure for its covered positions using the same model(s) used to calculate the VaR-based measure, subject to the same confidence level and holding period applicable to the VaR-based measure under § 324.205, but with model inputs calibrated to historical data from a continuous 12-month period that reflects a period of significant financial stress appropriate to the FDIC-supervised institution's current portfolio. (2) The stressed VaR-based measure must be calculated at least weekly and be no less than the FDIC-supervised institution's VaR-based measure. (3) An FDIC-supervised institution must have policies and procedures that describe how it determines the period of significant financial stress used to calculate the FDIC-supervised institution's stressed VaR-based measure under this section and must be able to provide empirical support for the period used. The FDIC-supervised institution must obtain the prior approval of the FDIC for, and notify the FDIC if the FDIC-supervised institution makes any material changes to, these policies and procedures. The policies and procedures must address: (i) How the FDIC-supervised institution links the period of significant financial stress used to calculate the stressed VaR-based measure to the composition and directional bias of its current portfolio; and (ii) The FDIC-supervised institution's process for selecting, reviewing, and updating the period of significant financial stress used to calculate the stressed VaR-based measure and for monitoring the appropriateness of the period to the FDIC-supervised institution's current portfolio. (4) Nothing in this section prevents the FDIC from requiring an FDIC-supervised institution to use a different period of significant financial stress in the calculation of the stressed VaR-based measure.
