Bank credit ratings
This page provides the current credit ratings for registered banks in New Zealand and some explanation of credit ratings.
What is a credit rating
A credit rating is an independent opinion on the capability and willingness of a financial institution to repay its debts — in other words, its financial strength or creditworthiness.
Credit ratings give investors an indication of a financial institution's relative strength, the likelihood that it will default and fail to replay investors. Credit ratings help investors assess whether the risk of investing is balanced by the rate of return on an investment.
A credit rating requirement is also likely to enhance incentives for banks to operate their business prudently to avoid a rating downgrade.
What banks must do
Under section 80 of the Reserve Bank of New Zealand Act 1989, we require registered banks to obtain and maintain a current credit rating applicable to their long-term, senior, unsecured obligations payable in New Zealand, in New Zealand dollars.
Banks may obtain a credit rating from Standard & Poor's, Moody's Investor Service or Fitch Ratings.
Registered banks must publish their credit rating in 6-monthly disclosure statements.
Registered banks' credit ratings
The ratings in the table below are obtained from banks' 6-monthly disclosure statements and credit rating agency reports.
We have made reasonable efforts to ensure these ratings are the most up to date rating applicable to the bank concerned. However, we cannot guarantee that a rating will be the most current one in all circumstances.
Total number of registered banks: 27

Comparing credit ratings
Different ratings systems are broadly comparable. For instance, an ‘AA’ rating from Standard & Poor’s and Fitch and an ‘Aa’ rating from Moody’s all imply that the chance of the rated organisation defaulting is approximately 1 in 300 over the next five years.

What credit ratings cannot do
Credit ratings are not a guarantee that a bank will be safe in the future. Indeed even an ‘AAA’ rated bank has an approximately 1 in 600 chance of default over a 5-year period. Although ratings are periodically revised, they are designed to provide a medium-term view of an institution’s financial strength. They do not respond to specific events or market volatility.
Credit ratings as investment advice
While credit ratings are useful indicators of risk for investors, they should not be relied on solely to make investment decisions.
Their key benefits lie in their availability, ability to convey a simple measure of risk, and that they allow investors to easily compare alternative opportunities. However, prudent investors should always consider their own personal circumstances, their willingness to take risks or otherwise, available investment strategies, and prevailing market conditions before making investment decisions.
