Liquidity at risk
Liquidity at risk (LaR) is a financial risk measure that estimates the potential net cash outflows an institution may face over a specified time horizon and confidence level. It is designed to quantify the risk that a bank, investment fund, or corporation will be unable to meet its short-term obligations due to unexpected demands on liquidity. The concept is closely related to Value at Risk (VaR), but instead of focusing on market value fluctuations, LaR models the probability distribution of future cash flows, including margin calls, credit drawdowns, and contingent liabilities.
LaR is used in liquidity risk management to assess funding adequacy under normal and stressed conditions, and it has been discussed in both academic research and regulatory contexts as a complement to stress testing and supervisory liquidity ratios such as the Liquidity coverage ratio (LCR) under Basel III. While proponents highlight its ability to provide a probabilistic framework for liquidity planning, critics note that LaR, like VaR, is sensitive to model assumptions and may underestimate extreme events.
