Liquidity at risk (Ofer Abarbanel online library)

The Liquidity-at-Risk (short: LaR) is a quantity to measure financial risks and is the maximum net liquidity drain relative to the expected liquidity position which should not be exceeded at a given confidence level (e.g. 95%). The LaR is analog to the Value-at-Risk (VaR) where a quantile of the EBIT-distribution is considered, however it does take stochastic cash flows into account.[1][2]


Statistical measures for financial risk are not intuitive. Increasing the confidence level (e.g. from 99.0% to 99.9%) does not capture very rare events with possibly high impact. The only way around is to use extreme value theory for modelling the distribution tails. In other words: Statistical liquidity risk modelling approaches do not provide certainty in terms of a reliable lower limit for future liquidity.
