This paper focuses on the issue of post-crisis banking regulations in the European Union and issues related to ensuring compliance with them and minimizing enforcement actions related to them. The aim of this paper is to consider the nature of enforcement actions in the post-crisis years. Based on the analysis, the hypothesis was formulated that the importance of regulatory compliance increases with the intensification of the enforcement actions of banking supervision authorities. The research question arises whether compliance units can identify non-compliance in advance and prevent or minimize the application by the supervisor of enforcement actions. The article attempts to describe the unexplored dependencies between the increase in regulatory requirements for banks in the post-crisis years and the dynamics of enforcement actions.
