The theory of financial intermediation highlights various channels through which capital and liquidity are interrelated. Using a simultaneous equations framework, we investigate the relationship between bank regulatory capital and bank liquidity measured from on-balance sheet positions for European and U.S. publicly traded commercial banks. Previous research studying the determinants of bank capital buffer has neglected the role of liquidity. On the whole, we find that banks decrease their regulatory capital ratios when they face higher illiquidity as defined in the Basel III accords or when they create more liquidity as measured by Berger and Bouwman (2009). However, considering other measures of illiquidity that focus more closely on core deposits in the United States, our results show that small banks strengthen their solvency standards when they are exposed to higher illiquidity. Our empirical investigation supports the need to implement minimum liquidity ratios concomitant to capital ratios, as stressed by the Basel Committee; however, our findings also shed light on the need to further clarify how to define and measure illiquidity and also on how to regulate large banking institutions, which behave differently than smaller ones.

There is a considerable debate on the role played by market discipline in the banking industry. Using data for 207 banks across 10 Central and Eastern European countries, this paper empirically analyzes the disciplining role of interbank deposits. We find that market discipline has been effective in Central and Eastern Europe since the implementation of explicit deposit insurance. However, several factors affect the strength of this discipline. State-owned banks are not disciplined probably because they benefit from implicit insurance. Institutional and legal factors, and resolution strategies adopted by countries during banking crises also impact bank risk and the effectiveness of market discipline. Our results indicate that stronger regulatory discipline reduces risk but also weakens market discipline.

International audienceWe assess the extent to which stock market information can be used to estimate leading indicators of bank financial distress. We specify a logit early warning model, designed for European banks, which tests if market based indicators add predictive value to models relying on accounting data. We also study the robustness of the link between market information and financial downgrading in the light of the safety net and asymmetric information hypotheses. Some of our results support the use of market-related indicators. Other results show that the accuracy of the predictive power depends on the extent to which bank liabilities are market traded
