According to Moody’s, New Zealand banks will benefit from tighter rules on high-LTV mortgage loans.It is also worth noting how the market responded to earlier less aggressive macroprudential measures.
On 19 July, the Reserve Bank of New Zealand (RBNZ) released a consultation paper outlining a proposal to limit bank lending to home investors at loan-to-value ratios (LTVs) above 60% to 5% of new originations and lending to owner-occupiers at LTVs above 80% to 10% of new lending. These restrictions are credit positive for New Zealand banks and their covered bond programs because they reduce their exposures to higher-risk lending at a time when house prices are at historic highs.
The proposal will be particularly beneficial to New Zealand’s four major banks, ANZ Bank New Zealand Limited, ASB Bank Limited, Bank of New Zealand and Westpac New Zealand Limited. These four banks hold approximately 86% of all New Zealand residential loans.
The tighter restrictions on LTV limits will benefit banks and their cover pools by providing a buffer against declining house prices before the size of the loan exceeds the value of the property. In the longer run, banks will have fewer high LTV loans to sell into their cover pools, which will strengthen the pools’ credit quality.
The new rules would replace existing limits that restrict new lending to investors in Auckland at LTVs greater than 70% to 5%, lending to owner-occupiers in Auckland at LTVs above 80% to 10%, and all other housing lending outside of Auckland at LTVs above 80% to 15%. The proposal is in response to the boom in New Zealand house prices, which are at historical highs, creating a sensitivity to a sharp reversal in home prices.
Although LTV restrictions protect banks against a sharp correction in house prices, it remains to be seen how effective these measures will be in moderating house price appreciation if interest rates decline further. In March 2016, the Reserve Bank of New Zealand reduced its policy rate by 25 basis points to 2.25%, the fifth reduction since June 2015, while also stating that further policy easing may be required. Furthermore, strong immigration and supply shortages continue to support house prices, particularly in Auckland.
The first of New Zealand’s macro-prudential measures, introduced in October 2013, had a sharp but temporary effect on house price growth. Further measures were introduced in 2015 that also immediately reduced house price growth in fourth quarter of 2015. However, prices rebounded and have appreciated in 2016.
The Reserve Bank of New Zealand is inviting market feedback on its proposal until 10 August, after which, a final policy will be released to take effect from 1 September 2016.
