This instrument addresses deficiencies in retained EU law in Regulation (EU) 575/2013 "the CRR" - a core part of the EU’s prudential regulation regime for banks, building societies and investment firms. Regulation (EU) 2019/876 "CRRII" amends the CRR updating the regime’s approach to the setting of capital requirements and the resolution of banks. Several of the amendments became applicable across the EU in June 2019. This SI therefore addresses the deficiencies resulting from the more recent changes made by CRRII, but only those changes that will be applicable in the UK by 31 October 2019.
