Using supervisory data from large U.S. bank holding companies (BHCs), we document that BHCs suffer more operational losses during episodes of extreme storms. Among different operational loss types, losses due to external fraud, BHCs' failure to meet obligations to clients and faulty business...

Recent regulatory proposals tie a financial institution's systemic importance to its complexity. However, little is known about how complexity affects banks' risk management. Using the 1996-1999 deregulations of U.S. banks' nonbanking activities as a natural experiment, we show that banks'...

This research aims to investigate the influence of bank capital, risk-based capital and bank capital buffers on the behaviour of bank risk-taking by applying GMM on the data of US commercial banks ranges from 2002 to 2018. The findings show that bank capital has a positive influence on total...

This paper analyzes banks' capital and risk-based capital (RBC) ratios as predictors of risk. Using quarterly data on U.S. bank holding companies (BHCs) from 1997 through 2010, we regress the capital and RBC ratios against six balance-sheet and market-based indicators of risk. Although both the...

Using supervisory operational loss data of the U.S. banking industry, we analyze correlations among operational losses within banks and across banks. We find evidence of relatively high correlations among tail losses of different operational risk types within banks. The median of these...

This study documents the association between the quality of risk management practices and operational loss realizations at large financial institutions in the United States. Using detailed supervisory data, we find that companies with weak risk management practices experience higher and more...

We examine the impact of the U.S. withdrawal from the Paris Agreement on the relationship between climate risk and systemic risk of U.S. global banks. We find that after 2017, investors stopped pricing climate risk into U.S. systemic risk directly, consistent with domestic investors expecting...

We build on the estimated sectoral effects of climate transition policies from the general equilibrium models of Jorgenson et al. (2018), Goulder and Hafstead (2018), and NGFS (2022a) to investigate U.S. banks’ exposures to transition risks. Our results show that while banks’ exposures are...
