 The IGA was signed by 26 EU member states (all except Sweden and the United Kingdom, the latter which withdrew from the EU) on 21 May 2014 and is open to accession to any other EU member states.It was to enter into force on the first day of the second month following the deposit of instruments of ratification by states representing at least 90% of the weighted vote of SSM and SRM participating states, and was applied from 1 January 2016, since the Regulation had entered into force, but only to SSM and SRM participating states.Some of the provisions of the Regulation were applied from 1 January 2015, but the authority to carry out bank resolutions did not apply until 1 January 2016, and were subject to the entry into force of the IGA.
