On January 13, 2015, the Capital Requirements (Capital Buffers and Macro-prudential Measures) (Amendment) Regulations 2015 were published.

The Regulations amend the Capital Requirements (Capital Buffers and Macro-prudential Measures) Regulations 2014 to introduce a systemic risk buffer (SRB) that will apply to ring-fenced banks (RFBs) and certain large building societies. This measure implements Articles 133 and 134 of the Capital Requirements Directive IV (CRD IV).

The Financial Policy Committee (FPC) will be responsible for setting out the framework for determining which institutions should hold the buffer and, if so, how large the buffer should be. It will need to publish this methodology by May 31, 2016. The Prudential Regulation Authority (PRA) will be responsible for applying the framework and will have ultimate discretion over which firms must hold the buffer and its size.

The Regulations were made on January 12, 2015 and come into force, unless otherwise stated, on May 31, 2016. The systemic risk buffer is applicable from January 1, 2019.  Regulations.
