Banks’ conduct costs in the post-crisis era continue to be a matter for concern, and they remain even more relevant in the current Covid-19 crisis, as they indicate how successful banks have been in restructuring their culture, articulating the desired culture, and maintaining their cultural vision. The CBR Conduct Costs Project aims to foster transparency in financial activity and to deliver a category of benchmarking, which comprises the level of conduct costs and the conduct risk of the banks, as an analytical tool for the banks and their stakeholders. The Project also provides valuable insight into banks’ culture, conduct, competence, and regulatory risks. We argue that the use of clear and publicly available metrics for banks’ conduct costs is an important step forward to ensure the trustworthiness of the banking sector, and it is paramount to foster an ethical culture in financial firms. This report discusses the financial consequences of bank misconduct for twenty of the world’s leading banks, from January 2008 to December 2018.
