This study examines whether risk disclosure and risk committee are associated with major banks’ performance worldwide. We also test whether the composition of a risk committee moderates (i.e. strengthens or weakens) this relationship. Using 1760 bank-year observations of 160 banks across 45 countries for the years 2006–2016, we find that risk disclosure and risk committees are associated with a bank’s overall performance. In addition, the findings suggest that the composition of a risk committee moderates the relationship between risk disclosure and bank performance. The results support the contention that risk disclosure and risk committee can be used as a channel to optimise the performance of a bank. Conclusions reflect on how the agency, signalling, and resource-based theories inform this phenomenon. This paper advances our understanding of the role of risk committee characteristics on the relationship between risk disclosures and bank performance from both theoretical and empirical perspectives, suggesting risk committee is not a panacea for risk monitoring. However, the existence of a strong risk committee is vital for effective risk governance. Findings from this research may have valuable practical and policy implications, particularly in the banking sector.
