View source for Liquidity coverage ratio

The '''liquidity coverage ratio''' (LCR) is a regulatory requirement introduced under [[Basel III]] that mandates banks to hold sufficient high-quality liquid assets (HQLA) to cover their net cash outflows over a 30-day stress period. The ratio is calculated as:

'''LCR = Stock of HQLA / Total net cash outflows over 30 days'''

The LCR must equal or exceed 100%, meaning banks must hold enough liquid assets to survive a one-month run on their funding.

The LCR was a direct response to the [[2008 financial crisis]], during which many banks that appeared well-capitalized by traditional metrics proved unable to meet their short-term obligations because their assets were illiquid and their funding was fragile. The ratio addresses the distinction between '''solvency''' and '''liquidity''': a bank can be solvent — its assets exceed its liabilities — and yet fail because it cannot convert assets to cash quickly enough to meet withdrawals.

However, the LCR creates its own systemic effects. By defining a narrow set of assets as "high-quality liquid" — primarily government bonds and reserves at the central bank — the LCR concentrates demand for these assets, potentially distorting their prices and reducing market liquidity for other securities. During the March 2020 Treasury market turmoil, the very assets designated as HQLA became illiquid, forcing the Federal Reserve to intervene as dealer of last resort. The LCR thus exemplifies the [[Volatility paradox|volatility paradox]]: a regulation designed to protect against liquidity risk can amplify it when the protected assets themselves become the locus of stress.
