The Australian Prudential Regulation Authority (APRA) has announced two significant developments in its regulatory policy.

AustraliaCorporate/Commercial Law

The Australian Prudential Regulation Authority (APRA) has announced two significant developments in its regulatory policy this month that together signal a shift towards a more proportionate, streamlined and resilient prudential framework.

First, APRA has announced that it has finalised a set of amendments to its prudential standards, prudential practice guides and reporting standards, which together will remove Additional Tier 1 capital (AT1) from bank prudential and reporting frameworks. AT1's role as a loss-absorbing buffer will largely be replaced by Common Equity Tier 1 Capital (CET1) and Tier 2 Capital (Tier 2). The final amendments reflect industry feedback following a consultation period, as well as APRA's own revisions. The amendments will commence on 1 January 2027, and APRA expects banks to be compliant with the updated reporting requirements for the March 2027 quarter reporting period.
