The rise in contemporary risk and the resultant corporate failures has necessitated the need for the required attributes of risk committee that would minimize risk of firms. To this end, this study was set to find out the effect of risk committee effectiveness (RCE) on financial successes of quoted banks in selected three African countries. The study spanned from 2009 to 2018. The study focused specifically on risk committee diligence, committee composition, committee diversity, committee expertise, committee size and return on equity (ROE) of the countries selected from Africa namely Nigeria, South Africa and Ghana. More so, we controlled for financial leverage. Ex post facto research design was adopted for the study and panel data in relation to the study were sourced from the annual reports of the chosen banks in the selected countries. The study patterned after the fixed effect model (FEM) since the Hausman test supports the FEM. The FEM reported that the effect of RCE diligence and RCE compositions on bank performance in Nigeria, South Africa and Ghana is highly significant statistically at 5% level. Hence, the study concludes that RCE vis-à-vis risk committee diligence, committee compositions and leverage factors should be pivotal to the formulation of risk management committee of organisations.
