The Australian Prudential Regulation Authority (APRA) published an information paper on December 23, laying out its framework for dealing with Australia's domestic systemically important banks (D-SIBs). Under this regime, D-SIBs will be subject to an extra 1 per cent common equity tier one (CET1) requirement as the local higher loss absorbency (HLA) treatment – which APRA says is "at the lower end of the range used elsewhere".
