Capital Review dual reporting and other changes to bank disclosure statements

We are planning to make changes to New Zealand-incorporated registered banks’ disclosure statements. These changes are to implement the Capital Review decision on ‘dual reporting’ that impacts banks accredited to use their own internal-ratings based (IRB) models to calculate risk weighted assets (RWAs) for credit risk. The changes also require some additional disclosure on capital adequacy by all New Zealand-incorporated banks.

Update on timing

We received a number of helpful submissions in response to the consultation paper, suggesting various changes to our proposals. We are giving these careful consideration. 

Due to policy prioritisation we are amending our implementation timetable. We now expect that the changes will come into force for disclosure statements with reporting dates of 31 March 2024 or later.

Background to consultation

We consulted on changes to the information that New Zealand-incorporated registered banks must publish in their six-monthly disclosure statements.

The main changes are to introduce ‘dual reporting’, which was one element of the Capital Review final policy decisions published in December 2019.

See Review of the capital adequacy framework registered banks

Our capital adequacy framework allows for some banks to be accredited to use their own internal models to calculate some of the risk-weighted assets (RWAs) for credit risk: we refer to such banks as modelling banks. Banks otherwise have to calculate their RWAs using the standardised approach, with risk-weights prescribed by us.

Dual reporting refers to additional information that a modelling bank would include in its disclosure statements. The additional information would be the bank’s RWAs and resulting capital ratios recalculated as if the bank was subject to the standardised approach. The main objective of dual reporting is to show how the use of internal models affects a bank’s RWA outcomes compared to using the standardised approach.

We also proposed some other additions to modelling banks’ disclosure requirements, to provide greater clarity around changes to their capital ratio calculations that came into force on 1 January 2022. 

In addition, we consulted on some other minor additions to disclosure statements for all New Zealand-incorporated banks, whether or not they are modelling banks. These additions are to provide more detail in the disclosure of RWAs for counterparty credit risk: this refers to a bank’s risk of loss from the failure of a counterparty to a derivative contract.

In the Consultation Paper, we proposed that these changes would take effect for disclosure statements with reporting dates of 30 September 2022 or later.

How to make a submission

We invited submissions on this Consultation Paper by 3 May 2022.

Please note the disclosure on the publication of submissions detailed in the consultation document.
