NZ Property Market Update: What Rising Oil Prices Mean in 2026

MARKET UPDATE: Oil prices have risen sharply after disruption in the Strait of Hormuz. For New Zealand, the main property-market risks are inflation pressure, delayed rate cuts, and weaker confidence, rather than an immediate housing downturn.

Rising oil prices and escalating conflict in the Middle East are creating fresh uncertainty for the New Zealand economy in 2026. This market update looks at what that could mean for inflation, interest rates, and property market sentiment, and why uncertainty does not necessarily change the underlying direction of housing markets.

Rising oil prices are creating uncertainty in the New Zealand economy in 2026

What is happening now?

Following joint US-Israeli military strikes on Iran in late February 2026, Iran declared the Strait of Hormuz closed and began targeting merchant shipping. Tanker traffic through the strait has dropped dramatically. The US military has launched operations to reopen the waterway, but the situation remains fluid.

Oil prices have risen above US$100 a barrel. In New Zealand, that’s already showing up at the petrol pump and starting to feed into freight and transport costs. Bank economists have begun revising their growth and inflation forecasts. Westpac now expects GDP growth of 1.9% for 2026, down from 2.8% previously, and sees inflation peaking around 4% by mid-year. ASB has made similar adjustments.

Those are meaningful revisions, but they come with an important caveat: they’re based on assumptions about how long the disruption lasts. If the strait reopens sooner than expected, or alternative supply routes absorb more of the shortfall, the picture could improve. If conditions worsen or persist, the numbers may shift further. It’s early, and much depends on what happens next.

What is the Reserve Bank doing?

Governor Anna Breman has been measured and clear. In a recent speech, she signalled that the RBNZ will look through the first-round impact of higher energy prices on near-term inflation. The Bank’s focus is on whether cost pressures become embedded in wages and broader pricing behaviour, the second-round effects, that would require a policy response.

Westpac expects the OCR to hold at 2.25% at the 8 April review. The economy entered this shock with spare capacity, unemployment at 5.4%, and room in the system. That’s meaningfully different from most previous oil crisis. This time around, the slack acts as a buffer.

Markets have been more reactive. Wholesale interest rates lifted and swap pricing briefly reflected OCR rises by year end. Most bank economists think that overstates the likely response. Westpac’s central case is for just one 0.25% increase later in 2026, with any more significant tightening pushed into 2027.

For mortgage holders and prospective buyers, the practical message is that rates are unlikely to fall further in the near term, but a sharp tightening cycle is not the base case. The more likely path is an extended hold, with the RBNZ watching developments closely before committing in either direction.

A short historical perspective

This is not the first time an oil shock has tested property markets. The useful starting point is the broader pattern: how have these episodes actually played out, and what do they tell us about what to expect?

1990–91 Gulf War

A useful benchmark because it showed how quickly an oil shock can become a broader market story. Iraq’s invasion of Kuwait removed roughly 4 million barrels per day from the market. Prices spiked but came back relatively quickly once the military situation resolved.

2003 Iraq War

A reminder that markets often price fear before the event, then reassess once the path becomes clearer. Oil rose on uncertainty but never reached crisis levels.

2011 Libya disruption

A stronger example of what happens when real supply leaves the market rather than markets simply worrying about it.

2019 Saudi facility attacks

A sharp energy jolt that mattered for oil immediately but did not become a lasting property market event.

2026 Strait of Hormuz disruption

The strait normally handles roughly 20% of global oil supply and a significant share of LNG. That makes this potentially more significant than most of the post-1990 episodes. The USA Federal Reserve has drawn comparisons with the larger supply disruptions of the 1970s and 1990, though how the current situation ultimately compares will depend on how long the disruption persists and how effectively alternative supply routes absorb the shortfall.

The consistent lesson across these episodes is that housing markets are affected indirectly. How much they are affected is traditionally shaped mainly by the phase the property cycle is in at the time. If the market is in a slump that slump can become protracted or worse but in 2026 with the property market in a recovery phase the downside impacts on the property market are likely to be minimal.

The recovery may last longer however because the property market has been relatively flat for several years, after the sharp drop of the post the COVID era, that means prices have little, if any, downside from current levels. There may be some panic selling in the short term but that is likely to only reflect those financially stretched owners who must sell.

The last 5 years have already resulted in most stretched owners selling already so any short term ‘panic sales’ are unlikely to redefine the phase of the cycle the market is experiencing.

Oil matters when it has a longer (second-round) impact on inflation rate expectations, mortgage pricing, or confidence, not simply because it’s on the front page today.

Transmission of second-round influences, if they emerge, take time to run through lending conditions, supply, migration, incomes, and local buyer confidence. That’s especially true for markets like Auckland, Tauranga, and Queenstown, which still move primarily on domestic factors.

What varies is the force behind those indirect channels. Right now, that force is real but still being assessed.

What does this mean for property buyers?

Overseas conflict can affect New Zealand mainly through higher fuel costs, pressure on inflation, possible changes to interest rate expectations, and weaker confidence among buyers. All of those are in play right now to some degree.

But it doesn’t follow that the housing market stops functioning, or that every buyer should move to the sidelines. A nervous market can still offer good buying conditions including less competition, longer listing times, and more room for disciplined negotiation. For buyers who have their lending sorted and aren’t relying on rate cuts, those are real advantages.

The questions that matter are the same ones that always matter:

• Can you comfortably service the lending at current rates?

• Are you buying a property that fits your long-term needs or strategy?

• Are you purchasing at a price that makes sense in today’s market?

• Can you hold through a period of uncertainty without becoming a forced seller?

If the answer to those questions is yes, then waiting for perfect certainty can become its own risk.

The danger of waiting too long

Many buyers tell themselves they’ll act once things feel clearer. But by the time the market feels safe again, confidence has often already returned, more buyers have re-entered, competition has increased, and prices can begin moving before everyone feels ready. That’s how windows of opportunity quietly close. The market rarely rings a bell at the bottom.

Our current view

Our reading is that the global situation is serious and the economic outlook for 2026 has shifted. Growth will be softer, inflation will be higher, and the housing market will reflect that for a period.

But the RBNZ is holding rates steady. The economy has spare capacity that limits the risk of an inflation spiral. Mortgage rates are more likely to hold than to spike sharply. And a more cautious market creates room for well advised buyers to negotiate selectively and focus on quality rather than urgency.

For clients who are financially ready, this may still be a worthwhile time to buy carefully. Not every environment needs to feel comfortable to be a good one. In markets like Auckland, Tauranga, and Queenstown, a period of hesitation can be exactly when the most disciplined buyers make their strongest moves.

The right mindset now

The best approach in uncertain times is not recklessness and not paralysis. It’s clear thinking, strong advice, conservative numbers, disciplined property selection, patience where needed, and confidence where justified.

The buyers who do best over time are usually not the ones who wait for fear to disappear. They’re the ones who learn to move carefully while fear is still in the room.

Summary

History helps here. From the Gulf War onward, Middle East oil shocks have repeatedly mattered to markets. The 2026 Hormuz disruption is more significant than most of the recent episodes, and it’s already affecting New Zealand through fuel costs, inflation expectations, and confidence. How far those effects go depends on how the situation develops from here.

So while caution is appropriate, stepping back completely may mean missing the advantages that uncertainty can create. At Staircase, our role is to help clients cut through the noise, understand the risks properly, and make calm, well-grounded property decisions with confidence.
