Journal Article
Public disclosure and risk-adjusted performance at bank holding companies
This article examines the relationship between the amount of information disclosed by bank holding companies (BHCs) and the BHCs? subsequent risk-adjusted performance. Using data from the annual reports of BHCs with large trading operations, the author constructs an index that quantifies the BHCs? public disclosure of forward-looking estimates of market risk exposure in their trading and market-making activities. She then examines the relationship between this index and subsequent risk-adjusted returns in the BHCs? trading activities and for the firm overall. The key finding is that more ...

An Evaluation of Bank VaR Measures for Market Risk During and Before the Financial Crisis
We study the performance and behavior of Value at Risk (VaR) measures used by a number of large banks during and before the financial crisis. Alternative benchmark VaR measures, including GARCH-based measures, are also estimated directly from the banks' trading revenues and help to explain the bank VaR performance results. While highly conservative in the pre-crisis period, bank VaR exceedances were excessive and clustered in the crisis period. All benchmark VaRs were more accurate in the pre-crisis period with GARCH VaR measures the most accurate in the crisis period having lower exceedance ...

Risk management, governance, culture, and risk taking in banks
This article examines how governance, culture, and risk management affect risk taking in banks. It distinguishes between good risks, which are risks that have an ex ante private reward for the bank on a standalone basis, and bad risks, which do not have such a reward. A well-governed bank takes the amount of risk that maximizes shareholder wealth, subject to constraints imposed by laws and regulators. In general, this involves eliminating or mitigating all bad risks to the extent that it is cost effective to do so. The role of risk management in such a bank is not to reduce the bank?s total ...

Public disclosure and risk-adjusted performance at bank holding companies
This paper examines the relationship between the amount of information disclosed by bank holding companies (BHCs) and their subsequent risk-adjusted performance. Using data from the annual reports of BHCs with large trading operations, we construct an index of publicly disclosed information about the BHCs? forward-looking estimates of market risk exposure in their trading and market-making activities. The paper then examines the relationship between this index and subsequent risk-adjusted returns in the BHCs? trading activities and for the firm overall. The key finding is that more disclosure ...

CoVaR
We propose a measure for systemic risk, ?CoVaR, defined as the difference between the conditional value at risk (CoVaR) of the financial system conditional on an institution being in distress and the CoVaR conditional on the median state of the institution. Our ?CoVaR estimates show that characteristics such as leverage, size, maturity mismatch, and asset price booms significantly predict systemic risk contribution. We provide out-of-sample forecasts of a countercyclical, forward-looking measure of systemic risk and show that the 2006:Q4 value of this measure would have predicted more than ...
