(90)Authorities are expected to impose higher own funds requirements on global systemically important institutions (G-SIIs) in order to compensate for the higher risk that G-SIIs represent for the financial system and the potential impact of their failure on taxpayers. Where an authority imposes the systemic risk buffer and the G-SII buffer is applicable, the higher of the two should apply. Where the systemic risk buffer only applies to domestic exposures, it should be cumulative with the G-SII buffer or the buffer relating to other systemically important institutions (O-SIIs) which is applied in accordance with this Directive.
