The RBNZ inflation warning from Governor Breman flags upside risk ahead of the October OCR decision
Reserve Bank Governor Anna Breman (pictured above) has warned that rising global oil prices could push near-term inflation above the bank's September forecasts.
Breman delivered the remarks during a visit to Dunedin on Tuesday 22 September. She was accompanied by External Monetary Policy Committee member Prasanna Gai and Board Chair Rodger Finlay.
The RBNZ inflation warning came days after the bank's 2 September decision. At that meeting, the OCR was raised to 2.75% – a second consecutive 25 basis-point hike since tightening resumed in July.
Recovery is underway, but it varies across regions
The governor acknowledged New Zealand's economic recovery is advancing but not uniformly. GDP grew 0.2% in the three months to June, the bank's own data shows, despite the drag from higher oil prices and other global factors. She noted that the South Island was faring better than most, supported by resilient export activity, lower unemployment and a stronger housing market.
"Every region has its own story," Breman said. "Meeting people face-to-face helps us understand how current conditions are affecting businesses and communities, how they are responding, and the extent that the economic recovery is being felt."
Those in stronger South Island markets may approach borrowing decisions with greater confidence. Those in areas still waiting for the recovery to land will need more conservative structuring advice.
What does the RBNZ inflation warning mean for the October OCR decision?
The critical message for advisers came on inflation. Global oil prices have surged above US$100 a barrel in recent weeks. That has pushed 91 unleaded petrol to $3.34 a litre – levels not seen since June, according to the Gaspy fuel monitoring site. The RBNZ's September statement was built on assumptions that did not anticipate prices remaining at these levels.
"If higher oil prices persist, they are expected to result in somewhat higher near-term inflation than we assumed in the September Statement," Breman said.
That raises the probability of another OCR increase at the bank's next scheduled decision on 28 October. Westpac expects a pause in October and a further 25 basis-point hike to 3.00% in December. ASB now expects inflation to remain close to 4% over the remainder of 2026, having pencilled in 75 basis points of hikes for the year.
The RBNZ has been clear it is not on a preset course. But Breman's Dunedin remarks leave little doubt that upside inflation risk remains live.
How should advisers prepare clients for further rate rises?
The October review will be shaped by data released between now and then, particularly any further movement in crude prices. The New Zealand Institute of Economic Research (NZIER) has noted that fuel-driven cost pressure is filtering into broader business costs in construction, agriculture and transport. Spare capacity in the labour market is currently limiting firms' ability to pass those costs on.
Inflation above target pushes the RBNZ toward further hikes, but slowing growth constrains how far it can go. The October review will likely be a closer call than September's consensus decision.
Breman said the bank would assess incoming data before October, remaining focused on returning inflation to the 2% midpoint. Advisers should be preparing clients now for a rate rise – one that is not certain, but is far from ruled out.
