(A) The previous day's VaR-based measure as calculated under § 3.205; or

(1) A national bank or Federal savings association 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 § 3.205, 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 national bank's or Federal savings association's current portfolio.

(i) A national bank or Federal savings association may use the VaR model that it uses to determine specific risk under § 3.207(b) or another VaR model that meets the quantitative requirements of §§ 3.205(b) and 3.207(b)(1) to calculate its CVA capital requirement for a counterparty by modeling the impact of changes in the counterparties' credit spreads, together with any recognized CVA hedges, on the CVA for the counterparties, subject to the following requirements:

(A) The VaR model must incorporate only changes in the counterparties' credit spreads, not changes in other risk factors. The VaR model does not need to capture jump-to-default risk;

(B) A national bank or Federal savings association that qualifies to use the advanced CVA approach must include in that approach any immaterial OTC derivative portfolios for which it uses the standardized approach for counterparty credit risk methodology in paragraph (c) of this section according to paragraph (e)(6)(viii) of this section; and

(C) A national bank or Federal savings association must have the systems capability to calculate the CVA capital requirement for a counterparty on a daily basis (but is not required to calculate the CVA capital requirement on a daily basis).

(B) Use the historical observation period required under § 3.205(b)(2).
