The European Banking Authority published the first list of Other Systematically Important Institutions in the European Union. O-SIIs are institutions which have been deemed by national regulators to be systematically relevant in addition to the Global Systematically Important Institutions that have already been identified. The EBA has compiled the list based on the findings of the relevant national regulators across the EU. National regulators relied on the EBA Guidelines on the identification of O-SIIs, which included recommended uniform criteria, including size, importance (substitutability or financial system infrastructure), complexity (or cross-border activities) and interconnectedness of such institutions. The EBA’s guidelines on the identification of O-SIIs were developed in accordance with the Capital Requirements Directive and on the basis of internationally agreed frameworks established by the Financial Stability Board and the Basel Committee for Banking Standards. The EBA will publish an updated list of O-SIIs annually along with a revised definition of any CET1 capital buffer requirements set by national regulators.
