Banco de Portugal decided to apply a two-year phase-in regime of the other systemically important institution (O-SII) buffer published on 29 December 2015 to the identified Portuguese O-SIIs. The timeline for the phase-in of the O-SII buffer is 50% as of 1 January 2018 and 100% as of 1 January 2019.
 
Banco de Portugal has taken this decision after having duly notified the European Central Bank, under Article 5 of Council Regulation (EU) No 1024/2013 of 15 October 2013, and after having also consulted the National Council of Financial Supervisors, under  Article 2 (3) (c) of Decree-Law No 143/2013 of 18 October.
 
The application of a two-year phase-in regime of the O-SII buffer has the main purpose of ensuring a level playing field in terms of the decisions on the O-SII buffer between Portuguese institutions and their European peers operating in similar macroeconomic environments.

For this purpose, as set out in the legal and regulatory provisions, Banco de Portugal is publishing the table below with the names of the banking groups identified as O-SIIs in 2015 and their respective capital buffers, as a percentage of the total risk exposure amount. These buffers shall consist of Common Equity Tier 1 capital on a consolidated basis and shall be applicable from 1 January 2018.
