Soaring interest rates to crash New Zealand’s housing market

New Zealand’s housing market is staring down a potential crash.

Mortgage demand has already fallen hard, with new mortgage commitments slumping 27% in the year to January 2021, driven by a 51% crash in investor mortgages, according to the Reserve Bank of New Zealand (RBNZ):

This follows a sharp rise in fixed and floating mortgage rates. As shown in the next chart, 3-year fixed mortgage rates have risen from a low of 2.7% in April last year to 4.7% currently, whereas floating mortgage rates have risen from a low of 4.1% to 4.8%:

Fear of overpaying has driven New Zealand buyer sentiment to a 26-year low, according to the latest ASB housing confidence survey.

As noted this week by Real Estate Institute of New Zealand chief executive Jen Baird:

“There is now a fear of overpaying among buyers… As a shift of sentiment sets in and buyers are less willing, or unable, to pay the prices we saw toward the end of 2021, pressure will come on vendors to adjust their expectations to meet the market.”

Economists have predicted that New Zealand’s official cash rate – currently 1.0% – will peak at anything from 2.75% (ASB’s forecast) to 3.5% (Westpac’s forecast). If true, the corresponding lift in mortgage rates would likely have a devastating impact on New Zealand mortgage holders and the property market.

According to the latest RBNZ lending data, one-third of new mortgages originated in 2021 were at debt-to-income ratios above 6 times. That’s $32.6 billion worth of mortgages issued in 2021 alone that are highly sensitive to interest rate increases:

Highly leveraged lending has boomed in New Zealand.

Prime Minister Jacinda Ardern’s decision to ban interest rate deductibility on investor mortgages will also add to the pain, since property investors will have to shoulder the full cost of interest rate rises, rather than sharing the pain with the tax man.

New Zealand’s housing market is by far the most expensive in the English-speaking world, making it primed for a correction:

ANZ bank is tipping New Zealand house prices to plunge 10% in 2022.

Kiwis better hope that New Zealand’s bank economists are wrong and interest rates don’t rise another 1.75% to 2.5%. Because the nation’s highly leveraged mortgage borrowers will be in a world of pain and the nation’s housing market would likely experience a much bigger crash.
