RBNZ Reviews Capital Adequacy Framework

The New Zealand Reserve Bank has announced it is undertaking a comprehensive review of the capital adequacy framework applying to locally incorporated registered banks over 2017/18. The aim of the review is to identify the most appropriate framework for setting capital requirements for New Zealand banks, taking into account how the current framework has operated and international developments in bank capital requirements.

The Capital Review will focus on the three key components of the current framework:

  • The definition of eligible capital instruments
  • The measurement of risk
  • The minimum capital ratios and buffers

The purpose of this Issues Paper is to provide stakeholders with an outline of the areas of the capital adequacy framework that the Reserve Bank intends to cover in the Capital Review, and invite stakeholders to provide initial feedback on the intended scope of the review, and issues that might warrant particular attention. As feedback is received and decisions are made, some of these issues might fall away or be given a lower priority.

Detailed consultation documents on policy proposals and options for each of the three components will be released later in 2017, with a view to concluding the review by the first quarter of 2018.

Basis and framework for capital regulation

The Reserve Bank has powers under the Reserve Bank Act 1989 to impose capital requirements on registered banks. The Reserve Bank exercises these powers to promote the maintenance of a sound and efficient financial system, and to avoid significant damage to the financial system that could result from the failure of a registered bank.

The capital adequacy framework for locally incorporated registered banks is set out mainly in documents BS2A and BS2B of the Reserve Bank’s Banking Supervision Handbook. The framework is based on, but not identical to, an international set of standards produced by the Basel Committee on Banking Supervision.

The framework imposes minimum capital ratios. These are ratios of eligible capital to loans and other exposures. Exposures are adjusted (risk-weighted) so that more capital is required to meet the minimum requirement if the bank has riskier exposures.

The high-level policy options raised in this Issues Paper have the potential to result in reasonably significant changes to the New Zealand capital framework. It is expected, however, that any changes are likely to occur within a Basel-like framework.

The Reserve Bank invites submissions on this Issues Paper by 5pm on 9 June 2017
