The paper investigates the impact of solvency and liquidity regulation on banks' balance sheet structure. The Covid-19 pandemics shows that periods of sharp increase in risk aversion often result in liquidity strains for banks due to the volatility of long-term funding markets.
According to a simple portfolio allocation model banks’ liquidity increases when the regulatory constraint is binding. We provide evidence, using the “liquidity coefficient” implemented in France ahead of Basel III's Liquidity Coverage Ratio, of a positive effect of the solvency ratio on the liquidity coefficient. We also show that in times of crisis, measured by financial variables, French banks actually decreased the liquidity coefficient, with the transmission channel materialising mainly on the liability side.
