Bank Capital and Liquidity Risk: Influence of Crisis and Regulatory Intervention

Abstract

This study analyses how capital affects asset and liability liquidity risk in U.S. commercial banks during stable and crisis periods. We find that higher capital increases idiosyncratic liquidity risk by boosting cash and near-cash assets, raising fed funds sold, and reducing fed funds purchased. On the liability side, there is a shift from liquid to investment deposits and an increase in off-balance-sheet items. These patterns hold across crises, with some variation during covid-19 period. Our findings suggest that policymakers must balance capital regulations and ensure tailored crisis interventions and monitoring for specific liquidity components. Our results are largely robust to several alternate variable proxies and model specifications.
