Systemically important institutions

Global systemically important institutions (G-SIIs) and, subject to national discretion, other systemically important institutions (O-SIIs) must fulfil supplementary requirements concerning the amount of Common Equity Tier 1 capital they must hold as a buffer. These buffers aim to address the potential negative effects that these institutions might have on the international or domestic financial system if they were to fail.

The European Banking Authority has drafted technical standards and guidelines for identifying G-SIIs and O-SIIs.

To see all the G-SII and O-SII buffer rates notified to the ESRB, please refer to the overview of national capital-based measures.
