As policy‐makers in the United States contemplate a relaxation of financial regulation, our study contributes to this dialogue by testing the veracity of heightened standards of risk governance activities for US bank holding companies (BHCs). Our study examines evidence relating to the adoption of these standards by BHCs following regulatory intervention. We find that board‐level risk appetite practices have a profound association upon BHC performance and tail risk. Our estimates show that BHCs which adopt risk appetite practices exhibit a significant improvement in headline performance and reduced tail risk measures. Our research is relevant to academics by identifying the significance of this risk governance practice which has been introduced by global regulators. For practitioners (including board members, risk managers, policy‐makers and regulators), our study validates the efficacy of risk appetite frameworks as the future shape of financial regulation is being actively debated in the US.

Regulators generally discourage bank CEOs also holding the role of board Chairman, as this governance structure can hinder independent decision-making and effective risk oversight. This study examines the issue of CEO Duality, identifying a positive relation to greater risk-taking across a battery of sensitivity tests. In further analysis, the study controls for differences in supervisory monitoring levels to examine its impact. Banks led by CEO Chairmen which are subject to lower levels of supervision continue to report a robust association to risk-taking, as before. However, this association dissipates for banks which are subject to heightened supervisory monitoring. These findings indicate that agency costs related to Duality may be moderated by greater regulation. This paper weighs-in on the controversy relating to a single contentious governance structure (i.e., CEO Duality), thus informing boards, regulators and researchers of the need to consider the overall interplay of monitoring mechanisms.
