Definition
The Liquidity-at-Risk of a financial portfolio associated with a stress scenario is the net liquidity outflow resulting from this stress scenario: The liquidity shortfall in a stress scenario is thus given by the difference between the Liquidity-at-Risk associated with the stress scenario and the amount of liquid assets available at the point where the scenario occurs. The concept of Liquidity at Risk is used in stress testing. It is conditional on the stress scenario considered. By analogy with Value-at-Risk one may also define a statistical notion of Liquidity at Risk, at a given confidence level (e.g. 95%), which may be defined as the highest Liquidity at Risk that may occur across all scenarios considered under a probabilistic model, with probability higher than the confidence level. This statistical notion of Liquidity at Risk is subject to model risk as it will depend on the probability distribution over scenarios.Relation with other risk measures
Liquidity at Risk is different from other measures of risk based on total loss, such as Value at Risk, as it is based on an estimate of cash losses, or liquidity outflows, as opposed to total loss.See also
