New Zealand faces a period of stagflation-lite, with GDP growth slowing to 1.5% and inflation rising to 4.5% due to the Iran war shock. The RBNZ is expected to respond with OCR hikes starting late 2026, reaching 4.25% by 2027.
Key Takeaways
- 1.The Iran war has shifted the economic outlook toward a period of high inflation and subdued growth, with 2026 GDP forecast at 1.5%.
- 2.Inflation is expected to peak between 4-5% due to a 30% rise in petrol prices and related cost increases.
- 3.Monetary policy will tighten, with OCR hikes likely starting in September, aiming for a neutral 3.0-3.5% range and a peak of 4.25% by end 2027.
