The current rules on prudential requirements for credit institutions and investment firms are established by Directive 2013/36/EU and Regulation (EU) No 575/2013, collectively known as CRD IV/CRR.
These rules provide empowerments for the adoption of a large number of delegated and implementing acts in order to enable the so-called Single Rulebook. The term Single Rulebook refers to the aim of a unified regulatory framework for the EU financial sector that completes the single market in financial services. Its purpose is to ensure uniform application of Basel III in all Member States and close regulatory loopholes.
