This box reviews the objectives and design of the liquidity coverage ratio (LCR) in the Basel Framework. It explains why liquidity regulation was introduced and how it is calibrated to enable banks to withstand a predefined hypothetical stress scenario combining both market-wide and idiosyncratic stress elements. The box also highlights the fact that the LCR is not designed to cover all tail events involving liquidity risk. Based on data for significant euro area (EA) institutions, the box finds that around 92% of all observed net outflow rates for retail deposits were lower than the outflow rates assumed in the LCR between 2016 and 2023. It also shows that ample liquidity buffers helped significant banks in the euro area to withstand the banking stress seen in March 2023 in other jurisdictions. Nevertheless, further analysis, including on the driving factors for some of the outliers observed during stress episodes, could facilitate a better understanding of whether the LCR calibration is working as intended. To anticipate and address extreme tail events (as well as risks) not covered by the LCR, liquidity regulation needs to be complemented by frequent and granular reporting as well as rigorous supervision.
