Systemically Important Institutions

The objective of the Other Systemically Important Institutions (O-SII) buffer is to reduce the potential impact of a systemically important financial institution’s failure on the domestic economy. The Central Bank, together with the ECB, is responsible for identifying O-SIIs for Ireland and setting buffer rates.
