Bank Liquidity Dynamics During Financial Crises

Summary

Bank liquidity dynamics during financial crises centre on the capacity of institutions to convert assets into cash and to meet sudden surges in withdrawal or margin calls. Crises expose maturity mismatches, in which short-term liabilities cannot be met without liquidating longer-term assets, often at depressed prices. This vulnerability is compounded by confidence shocks that trigger fire sales and funding freezes, amplifying contagion across interbank markets. Central banks and regulators intervene with liquidity facilities and backstop mechanisms, yet these measures can introduce moral hazard and opacity as institutions adjust their balance sheets to meet new requirements. The interaction between solvency and liquidity risks further complicates crisis management, since capital shortfalls may force premature asset sales or reliance on emergency funding. Global research highlights the importance of coherent stress-testing frameworks that integrate liquidity buffers with capital adequacy, while recognising the trade-offs between stringent regulation and banks’ willingness to supply credit. Practical applications range from designing contingent liquidity lines to calibrating macroprudential tools that mitigate systemic spill-overs without stifling intermediation.
