If you've been watching the news lately, you'll know the conflict in Iran is more than a geopolitical story — it's a financial one that's
starting to ripple all the way to New Zealand, including into your mortgage repayments.
Where NZ Mortgage Rates Stand Right Now
After a prolonged easing cycle, New Zealand's Official Cash Rate (OCR) has been held at 2.25% since November 2025, following cuts that reduced it by 325 basis points from a peak of 5.50%. For borrowers, this delivered some welcome relief.
But here's the catch — that relief is proving to be short-lived.
As of late April 2026, the lowest one-year fixed mortgage rate now sits at 4.55% where it wasn’t that long ago 2-year rates were available for cheaper than this and there was some hope we would see a 1-year rate starting with a 3 in front of it.
Enter the Iran Factor
The conflict in Iran is adding serious pressure to an already uncertain picture. The war caused immediate volatility in energy markets, with Brent crude oil prices surging 10–13% to around $80–82 per barrel. Iran's closure of the Strait of Hormuz has disrupted approximately 20% of global oil supplies — what the International Energy Agency has characterised as the "largest supply disruption in the history of the global oil market."
For New Zealand, this matters in two key ways: fuel costs and inflation.
The New Zealand Government has already released petroleum reserves and introduced a $50 tax credit for eligible working families with children to help offset rising fuel costs. But higher energy prices don't stay at the petrol pump — they flow through to the price of virtually everything, from groceries to construction materials.
As we import all of our petrol in New Zealand, the main transmission channel is via inflation. Higher oil and gas prices raise import costs
for households and firms, squeezing real incomes and eroding purchasing power. This is critical for mortgage holders because elevated
inflation makes it much harder for the Reserve Bank to cut rates — and may even force it to raise them. Interest rate
reductions have been expected to be postponed, or conversely increased, in light of higher inflation caused by supply shortages.
