Treasury makes capital buffers rules: The Capital Requirements (Capital Buffers and Macroprudential Measures) (Amendment) Regulations 2015 will come into force partly on 31 May 2016 and partly on 1 January 2019. They implement in part the provisions of the fourth Capital Requirements Directive (CRD4) on systemic risk buffers. These Regulations set out what the Financial Policy Committee, Prudential Regulation Authority (PRA) and FCA must do. PRA and FCA rules will further implement the requirements.
