ADI capital reforms: Roadmap to 2023

In December 2020, APRA released a consultation package on revisions to the capital framework for authorised deposit-taking institutions (ADIs).1 These are significant policy reforms, and the consultation and implementation phase is an important part of the process.

This letter sets out a roadmap of next steps to 2023, when the new framework comes into effect.

Consultation process


The ADI capital reforms will embed the industry’s ‘unquestionably strong’ capital position, and improve the flexibility of the framework to respond during periods of stress. APRA is committed to meeting the 1 January 2023 implementation date, to complete the reforms and provide certainty for the industry in capital planning. 

The current round of consultation closed on 1 April 2021. Industry responses have been broadly supportive of the reforms, and have provided useful feedback on the impact of specific proposals. APRA is currently reviewing this feedback, including in particular analysis of the proposed capital requirements for higher risk residential mortgages. To ensure the reforms are in line with the objectives and meet the ‘unquestionably strong’ level of capital at a system level, APRA is continuing the consultation process this year.2  

Next steps


To provide a clear roadmap for consultation and industry engagement, APRA has set out an indicative timeline in Attachment A. The timeline covers key policy releases, reporting requirements, industry workshops and the process for capital model approvals. Over the course of 2021, APRA intends to:

  • Conduct a targeted data study, to assess potential changes to the calibration of the prudential standards;
  • Initiate regular workshops with industry as the standards and guidance are finalised, to provide a forum for updates and FAQs; and 
  • Release final prudential standards, draft prudential practice guides (PPGs) and initial details of reporting requirements by the end of the year. 

Over the course of 2022, APRA intends to finalise the PPGs and reporting requirements. There are a number of related policy revisions that will also be progressed next year, including the fundamental review of the trading book and public disclosure requirements. APRA intends to conduct a parallel run of capital reporting on the new framework in late 2022.

How industry can prepare


APRA expects ADIs to be fully compliant with the revised capital framework from 1 January 2023, including the determination and reporting of capital adequacy. APRA will seek assurance from the relevant accountable person at each ADI on the accuracy of capital ratios. ADIs using the internal ratings-based (IRB) approach to credit risk will also need to seek APRA approval for relevant models, as part of the implementation of the reforms.

APRA notes the constructive engagement with industry during the consultation period to date, and looks forward to this continuing as the reforms are finalised. APRA will liaise with ADIs directly and via industry associations on the industry workshops. If you have questions on the roadmap or reforms more broadly, please contact your supervision team.

Yours sincerely,

Gideon Holland 

General Manager
