NZ Mortgage and Property Update: Westpac Hikes Rates as RBNZ Faces Inflation Pressure

Executive Summary

New Zealand’s mortgage landscape is shifting rapidly as wholesale interest rates rise, highlighted by Westpac increasing most of its fixed home loan rates effective May 22. Meanwhile, the broader property market is grappling with a combination of weak demand and a fuel-driven inflation shock, leaving economists deeply divided ahead of the Reserve Bank’s crucial May 27 Official Cash Rate announcement.

Key Takeaways

• Westpac rate increases: Westpac has raised most fixed mortgage rates, pushing its 18-month rate over 5% and setting a market-high 1-year rate of 4.79%.
• OCR speculation: Economists are split on the RBNZ’s May 27 decision, with some expecting a hold at 2.25%, while others point to market pricing that anticipates up to three 0.25% hikes this year.
• Mortgage sweet spot: ANZ economists currently highlight the one-to-two-year fixed terms as the optimal balance of cost and certainty for borrowers.
• Housing market stagnation: The national average home value sits at $912,406 (down 0.2% year-on-year), with momentum stalling amidst rising living and fuel costs.

Market Breakdown

Mortgage Rate Movements and the OCR Debate

Wholesale interest rates are facing significant upward pressure, largely driven by global uncertainties and fuel price shocks stemming from the Middle East. This has directly impacted retail lending. Effective May 22, Westpac increased most of its fixed-term home loan rates. The bank’s new 1-year rate of 4.79% is currently the highest among the major banks for that term, and its 18-month rate is the first in this cycle to cross the 5% threshold. However, Westpac held its 2-year rate steady, matching BNZ for the most competitive offer in that bracket.

All eyes are now on the Reserve Bank of New Zealand ahead of its May 27 Monetary Policy Statement. The OCR currently sits at 2.25%. While BNZ and others expect the RBNZ to hold the rate and look through the temporary inflation caused by fuel prices, Westpac’s chief economist has suggested a hike to 2.5% would be justified to curb rising inflation expectations, which are forecast to breach 4% this year. Conversely, independent housing researchers are urging the RBNZ to cut the OCR by 25 basis points to avoid pushing a vulnerable economy into recession.

Property Market Headwinds and Social Housing Shifts

The broader property market is showing signs of weakness. According to the latest QV House Price Index data, the average New Zealand home is now worth $912,406. While there was a marginal 0.2% increase in the April quarter, values remain 0.2% lower than the same time last year. ANZ notes that an earlier surge in housing momentum has been heavily disrupted by the current fuel price shock, which is draining household budgets and dampening buyer demand.

In the public sector, the Government announced major social housing reforms this week. The multi-year plan includes increasing the income-related rent contribution for social housing tenants to 30%, which will raise rents for approximately 84,000 households by an average of $31 per week. The projected operating savings are earmarked for reinvestment into higher Accommodation Supplement rates to support individuals in the private rental market.

Summary

For borrowers deciding whether to fix or float right now, the current environment demands a pragmatic approach to risk. With wholesale rates pushing bank pricing higher and the market pricing in potential OCR hikes over the coming year, floating leaves borrowers exposed to immediate increases. Currently, locking in a one-to-two-year fixed rate is viewed by major economists as the most sensible sweet spot. This strategy provides a shield against the immediate volatility of fuel-driven inflation shocks, while still offering the flexibility to reassess the market once the RBNZ’s long-term policy direction becomes clearer.
