This article aims to provide an overview of the current requirements of the consolidated prudential supervision of investment firms under Regulation (EU) 2019/2033 (Investment Firm Regulation (IFR)) and related legal acts. In particular, it considers the implications of the recently adopted Commission Delegated Regulation setting out regulatory technical standards with regard to the scope and methods for prudential consolidation of an investment firm group (RTS). Given the complexity of the topic, the introduction set out in this article does not touch on every aspect of consolidated prudential supervision in order to provide a concise overview.
