[en]This paper investigates the efficiency of leverage ratios and risk-weighted capital ratios as bank failure predictors during the global financial crisis. Analyzing 417 bank failures between 2008 and 2012, we find that the predictive power of different capital ratios is not homogeneous across banks. The simple leverage ratio outperforms the risk-weighted ratio in predicting failures of large banks, while both capital ratios are important in predicting the failure of smaller banks. The better performance of the leverage ratio in the case of large banks is especially important during the crisis period of 2008-2010. The findings support the regulatory reforms proposed by Basel Committee on Banking Supervision on the adoption of a supplementary minimum leverage ratio in order to strengthen the resilience of the bank sector.[/en]
