Other systemically important institutions capital buffer
The other systemically important institutions (O-SII) capital buffer is one of the instruments available in Banco de Portugal’s macroprudential toolkit aiming at addressing the macroprudential policy intermediate objective of preventing the building up of systemic risk arising from misaligned incentives and moral hazard.
According to section IV of title VII – A of the Legal Framework of Credit Institutions and Financial Companies, the designated authority may impose higher capital requirements on O-SIIs, between 0 and 2% of the total risk exposure amount, in order to compensate for the higher risk that these institutions pose to the financial system due to their size, importance for the economy of the Member State in question or the European Union, complexity or degree of interconnection with other financial sector institutions and, in the event of insolvency, the potential contagion of these institutions to the rest of the non-financial and financial sectors.
The O-SIIs capital buffer must be build up of Common Equity Tier 1 and be applied on a consolidated basis. It will be revised annually or if a significant restructuring process occurs, such as a merger or an acquisition.
In Portugal, since no global systemically important institution (G-SII) was identified, the G-SII capital buffer does not apply.
