Which regulation is focused on investment firms and credit institutions under CRD compliance?

The regulation that focuses on investment firms and credit institutions under CRD compliance is BIPRU, which stands for the Prudential Sourcebook for Banks, Building Societies and Investment Firms. This regulation outlines the capital adequacy framework that these financial entities must adhere to, ensuring they maintain sufficient capital to cover their risks and protect depositors and clients.

BIPRU is aligned with the Capital Requirements Directive (CRD), which is a set of EU directives aimed at improving the regulation and supervision of credit institutions and investment firms to promote financial stability. It details the capital requirements, risk management standards, and disclosure obligations that investment firms and credit institutions must observe.

Other regulations mentioned, such as INPRU and IFPRU, address specific aspects of prudential regulation but are not as comprehensive in covering the entirety of investment firms and credit institutions under CRD compliance. GENPRU, while relevant to general prudential rules, does not specifically focus on the investment firms and credit institutions as BIPRU does. Understanding BIPRU's applicability is crucial for compliance within the financial sector.
