Using U.S. banking data between 1993 and 2014, this paper investigates the relationship between CEO optimism and bank liquidity creation. It finds that banks with optimistic CEOs create more liquidity over the entire sample period. In addition, the positive effect of CEO optimism on liquidity creation became stronger during the subprime crisis of 2007‒2009, and this stronger effect was mainly driven by banks with high capital ratios and large banks. These results imply that CEO optimism is likely to encourage banks to create liquidity, especially during banking crises. The results presented in this paper hold when subjected to various robustness checks.

Using U.S. bank data from 1996 to 2013, this paper studies how liquidity risk affects bank performance in financial crises. It finds that during the subprime crisis of 2007–09, liquidity risk reduced a bank’s survival probability, ROA, and net interest margin, and increased its loan-loss-provision expenses. This adverse effect was more severe for banks with lower capital ratios and higher credit risk. In contrast, there is no strong evidence that liquidity risk hurts bank performance in market crises. The results in this paper imply that liquidity risk is not merely a symptom of banks’ insolvency problems; it has an independent effect on bank performance in banking crises.
