On 21 May 2014 the Central Bank updated its implementation notice on competent authority national discretions and options to reflect the national transposition of the Capital Requirements Directive IV (CRD IV) and Capital Requirements Regulation (CRR), which represent the EU implementation of Basel III, and which were agreed and finalised under the Irish Presidency of the EU Council. The Central Bank issued a preliminary Implementation Notice relating to Competent Authority Discretions and Options in CRD IV and CRR on 24 December 2013. CRD IV was transposed into Irish national law by the European Union (Capital Requirements) Regulations 2014 (S.I. 158/2014). As a directly applicable EU regulation, CRR did not require transposition into Irish law but aspects of CRR have been operationalised in Irish law through the European Union (Capital Requirements) Regulations 2014 (S.I. 159/2014). The Central Bank highlights the ESA Technical Standards arising under CRD IV and CRR and consequential amendments to existing national legislation. (see Part 10 of S.I. 158/2014).

UCITS Mancos and AIFMs among others must meet CRD IV requirements on initial capital, own funds and fixed overheads from 1 January 2014.

At EU level, three delegated Regulations on CRD IV Directive regulatory technical standards (RTS) were published in the Official Journal of the European Union (OJ). They come into force twenty days after their publication in the OJ, Five delegated Regulations on CRR RTS were published in the OJ and similarly come into force twenty days after their publication.
