Specifically, value at risk is a measure of losses due to “normal” market movements. Losses greater than the value at risk are suffered only with a specified small probability. Subject to the simplifying In (1a),ξ is a random vector defined on a probability space (, F, P). ρ (x,ξ) denotes a risk measure, where variance (see), absolute deviation (), VaR (), and CVaR ([3,42]) are usually used as Alpha. Alpha measures risk relative to the market or a selected benchmark index. For example, if … Risk measures are statistical tools and formulae that assess the risk involved in potential investments.

For credit risk measured using models such as the CreditMetrics and KMV that assume a one-year horizon, the one-year VaR is equivalent to risk capital. comparability of risk-based capital measures and reducing model complexity. 3. Building on this finding, the Committee has developed the Standardised Measurement Approach (SMA), which provides a single non-model-based method for the estimation of operational risk capital.
