New Zealand homeowners face an uncomfortable prospect: another interest rate increase while the housing market is still struggling to find its feet.
The Reserve Bank’s next Official Cash Rate decision is due on Wednesday, 28 October, with economists anticipating a rise from 2.75% to 3%.
That decision has not been made. But September’s inflation figures have strengthened the argument for another increase — and raised questions about how much more pressure households and businesses can absorb.
For the property market, the concern extends beyond next week’s announcement. It is whether borrowing costs will remain elevated well into 2027, delaying the recovery many vendors have been waiting for.
INFLATION HAS EASED — BUT THE PROBLEM HAS NOT DISAPPEARED
Stats NZ figures released on 22 October showed consumer prices rose 0.7% in the September quarter, taking annual inflation to 3.7%.
That was below June’s annual rate of 4.1%, but still above the Reserve Bank’s medium-term target range of 1% to 3%.
Domestic, or non-tradeable, inflation eased to 3.3%. Internationally influenced, or tradeable, inflation stood at 4.3%, with petrol prices around 19% higher than a year earlier.
Those figures create a difficult policy choice.
Households are already paying more for everyday essentials. Increasing interest rates adds another expense for borrowers, even though monetary policy cannot directly fix international oil supply problems.
The Reserve Bank’s concern is what happens next: whether sustained fuel and import costs spread through transport charges, business pricing and wage expectations.
WHY ANOTHER OCR INCREASE IS EXPECTED
The argument for raising the OCR rests on more than petrol.
BNZ’s latest inflation analysis found that 59.7% of items increased in price during the quarter, compared with 56.2% in the previous quarter. Its analysis also highlighted core inflation around 3%.
That suggests price pressure is becoming more widespread.
In the reporting supplied to Property Noise, BNZ chief economist Mike Jones said the bank expected an OCR increase next week, potentially accompanied by a signal that further tightening could follow.
ASB economists also expected increases in October and December, while warning that persistent inflation could require more action.
Property Noise previously examined ASB’s forecast for further OCR hikes and a lengthy recovery towards previous house-price peaks.
The latest inflation figures keep that difficult combination in focus: subdued property conditions alongside upward pressure on borrowing costs.
THE COUNTERARGUMENT: HOUSEHOLDS ARE ALREADY UNDER PRESSURE
Kiwibank chief economist Jarrod Kerr has questioned whether increasing rates is the right response to the current conditions.
His concern is that higher fuel prices are already reducing households’ spending power and squeezing businesses.
Businesses may want to recover their costs through higher prices. But customers with stretched budgets can make that difficult.
That matters because weak spending can itself restrain inflation.
Kerr’s position highlights the risk of tightening monetary policy while consumers remain cautious. He also acknowledged the Reserve Bank’s concern about waiting too long and allowing inflation to become entrenched.
The disagreement is therefore about timing and economic resilience, rather than whether inflation matters.
WHAT A MOVE TO 3% WOULD MEAN FOR MORTGAGES
A 25-basis-point increase would lift the OCR from 2.75% to 3%.
Mortgage rates would not necessarily increase by exactly the same amount.
Floating rates are more directly exposed to OCR changes. Fixed mortgage pricing also reflects wholesale funding costs, expectations about future interest rates, competition and banks’ margins.
Some anticipated tightening may already be reflected in advertised fixed rates.
Borrowers on existing fixed terms would generally retain their contracted rate until that term ends. Their exposure comes when they refix, refinance or take on additional borrowing.
Nevertheless, another OCR increase would reinforce a message that matters to buyers: assumptions about steadily falling mortgage costs may need revisiting.
THE PROPERTY MARKET’S DOUBLE SQUEEZE
A household can experience falling property wealth and rising borrowing costs at the same time.
A lower estimated home value does not reduce the mortgage balance. Meanwhile, a higher rate at refixing can increase repayments.
For vendors, that creates a difficult backdrop. Buyers may have substantial choice, but their ability to bid depends on what they can afford to borrow and repay.
For purchasers, a discount on the asking price can be helpful. It does not automatically translate into an affordable monthly mortgage.
Purchase price and ownership cost need to be considered together.
Our assessment is that another increase would add a headwind to housing demand. The size of that effect would depend on subsequent bank pricing, employment, household incomes and confidence.
It would not, by itself, establish that house prices must fall nationwide.
INVESTORS FACE ANOTHER TEST OF THE NUMBERS
For property investors, higher financing costs can place additional pressure on cash flow.
Rental income needs to be considered alongside interest, rates, insurance, maintenance and potential vacancy periods.
Investors cannot assume rents will rise sufficiently to cover every increase in ownership costs. Tenants’ ability to pay remains a constraint.
Nor should projected capital gains be treated as a substitute for a workable holding-cost calculation.
An OCR increase would therefore make careful assessment more important, particularly for purchases relying heavily on borrowed money.
COULD MORE INCREASES FOLLOW IN 2027?
Next week’s decision is only part of the interest-rate outlook.
Infometrics chief forecaster Gareth Kiernan argued in the supplied reporting that there was a case for returning the OCR towards an estimated neutral range of 3% to 3.25%.
Neutral is an estimate of the setting that neither stimulates nor restrains the economy. It is uncertain and can change.
ASB’s concern is that inflation could remain above 3% until late 2027.
These are economists’ assessments, rather than a confirmed Reserve Bank timetable.
The eventual path will depend on inflation, fuel costs, the exchange rate, business pricing and the strength of economic activity. If household spending weakens further, the case for additional increases becomes more complicated.
WHAT BUYERS AND SELLERS SHOULD WATCH NEXT
The headline OCR number will attract attention on 28 October. The Reserve Bank’s explanation could matter just as much.
Key questions include:
- Does the Bank signal that further increases are likely?
- How concerned is it about inflation spreading beyond fuel?
- Does it acknowledge greater pressure on households and businesses?
- How do banks adjust floating and fixed mortgage offers afterwards?
For vendors, realistic pricing and evidence from comparable sales remain important.
For buyers, affordability needs to work at the mortgage rate available to them, with room for other ownership costs.
An anticipated OCR increase is a reason to reassess the numbers carefully. It is not a decision already announced.
A DIFFICULT MOMENT FOR NZ HOUSING
The prospect of another increase challenges the idea that interest rates will arrive in time to rescue a sluggish property market.
Inflation has eased, but it remains above target. Households are under pressure, yet the Reserve Bank must also consider the cost of allowing inflation to persist.
For New Zealand property owners, the immediate risk is a longer wait for relief — with borrowing costs potentially rising before housing confidence meaningfully improves.
