Review of mortgage bond collateral standards

Status: Further consultation

Consultation period: 2017-2019

13 November 2018

The Reserve Bank is proposing a new mortgage bond standard aimed at supporting confidence and liquidity in the New Zealand markets.

This follows an initial consultation in November 2017 and ongoing discussion with issuers and investors over the past year.

The new mortgage bond standard aims to:

  • reduce contingency risks for the Reserve Bank as a lender of last resort and ensure financial intermediaries supply sufficient high quality and liquid assets; and
  • provide issuers and investors with an additional funding and investment instrument, supporting the development of deeper capital markets.

The consultation paper summarises the changes proposed in response to the key issues raised by industry and sets out the revised mortgage bond standard in an exposure draft for final consultation.

The Bank expects to issue final decisions in March 2019, and commence implementation from June 2019. A five-year transition to full implementation is proposed.

The consultation closes at 5.00 pm on Friday 22 February 2019.

17 November 2017

The Reserve Bank is proposing an enhanced mortgage bond standard aimed at supporting confidence and liquidity in the financial system. 

This follows a review of domestic and international mortgage bond collateral standards. 

The Bank believes the proposed new collateral standard would:

  • improve the risk position of the Reserve Bank by promoting the use of higher quality and potentially more liquid, mortgage bonds as collateral in the Bank’s lending operations;
  • support New Zealand market lenders by creating an additional funding instrument for residential mortgages; and
  • promote a deeper capital market through the availability of simple, comparable and transparent mortgage bond instruments.

The Bank is seeking feedback on the terms under which it accepts mortgage bonds as collateral and the proposed new Residential Mortgage Obligations (RMO) standard.

The consultation closed on Friday 9 March 2018.
