The Banking Supervision Handbook - banking supervision policy documents and regulations

This page contains the handbook documents and Orders in Council setting out the details of the policy framework and rules that apply to registered banks. The information is updated from time to time.

Proposed changes to the Banking Supervision Handbook

November 2017 - the Reserve Bank is consulting on changes to the registered bank disclosure requirements. The proposed changes include the removal of the requirement for off-quarter disclosure statements, to coincide with the start of the new Dashboard approach to quarterly disclosure. Other changes include a number of improvements agreed during the Regulatory Stocktake, and some other changes consequential on the Dashboard. The consultation paper is accompanied by red-lined versions of the Reserve Bank’s working copies of the disclosure Orders in Council, one for locally-incorporated banks and one for branches of overseas banks. The deadline for comments is 12 January 2018.

Recent changes to the Banking Supervision Handbook

September 2017 - the Reserve Bank has published a new Handbook document "Outsourcing Policy" (BS11) (PDF 252KB)  dated September 2017. This is a revision of the January 2006 BS11 designed to address shortcomings in how the 2006 policy was interpreted and to ensure a better alignment with the Open Bank Resolution (OBR) Pre-positioning Requirements Policy (BS17) (PDF 259KB). The revised policy includes a five year transitional path beginning on October 1 2017. Parts of the 2006 BS11 may remain relevant for banks until the end of the transitional period. A revised version of the "Statement of Principles - bank registration and supervision" (BS1) (PDF 387KB) with consequential amendments has been published at the same time.

Information on the handbook

Registered banks and their advisers are encouraged to make the handbook the first point of reference on specific matters relating to banking supervision. Where a matter is not addressed in the handbook, the matter should be raised with the Reserve Bank. In general, the appropriate contact person at the Reserve Bank will be the analyst responsible for the registered bank concerned.

You can subscribe to an email list which will keep you informed of updates to the Banking Supervision handbook. There is no charge for this service.

Accompanying documents for the outsourcing policy

Under the outsourcing policy (BS11) dated September 2017, the Reserve Bank may issue a list of exempt functions and services (the 'white list'). The Reserve Bank may also issue a List of Pre-approved Functions and Services. Banks may enter in arrangements captured on this list without requiring non-objection from the Reserve Bank but must still ensure such arrangements comply with the rest of the policy.

BS11 also allows the Reserve Bank to issue applications forms to assist banks.

Outsourcing Transitional:

The 2006 version of the Outsourcing Policy has been superseded. However, any bank that was subject to the Outsourcing Policy as at 30 September 2017 will continue to have to meet any relevant requirements of the 2006 policy for a transitional period of 5 years from that date, as well as being subject to the current version of the policy referred to in the main table above.
