All five major New Zealand bank economist teams expect the Reserve Bank to leave the Official Cash Rate unchanged at 2.25 percent when it announces its latest Monetary Policy Statement on Wednesday 27 May, even though headline inflation has now sat above the top of the target band for two quarters running.
The OCR has been held at 2.25 percent since November 2025, after a long easing cycle that took it down from a peak of 5.5 percent. Annual inflation hit 3.1 percent in the March 2026 quarter, the second consecutive reading above the Reserve Bank’s 1 to 3 percent target range, with the 2 percent midpoint slipping further out of reach. The Bank’s own April Monetary Policy Review forecast inflation could spike to 4.2 percent in the June quarter once the latest Iran related fuel shock works through the index.
Petrol prices jumped 12.6 percent and diesel 36.6 percent between March and April, after Israeli and US strikes on Iranian energy infrastructure pushed Brent crude back above one hundred US dollars a barrel. That shock has already filtered through to New Zealand tourism operators, with some paying more than twice what they did a year ago to fill a tour van.
Despite that backdrop, an Interest.co.nz survey of the major bank economists shows a consensus that the Monetary Policy Committee will sit on its hands this week, while leaving the door open to a rate hike later in the winter or early spring. ANZ chief economist Sharon Zollner and ASB economists Wesley Tanuvasa and Jane Turner both pencil in July as the most likely timing if a move is needed, with ASB describing July as the "sweet spot" because by then the Committee will have a full set of June quarter inflation and labour market data in hand.
BNZ head of research Stephen Toplis says a hike is possible at this meeting but unlikely, capturing the bind the Committee is in. "The RBNZ will be accused of tightening too quickly or too much," he wrote in BNZ's preview note. "Who'd want to be a Monetary Policy Committee member?"
Westpac chief economist Kelly Eckhold has gone further than his peers, arguing the Bank should actually move now to head off a second round of price increases. "We expect a live debate at the Monetary Policy Committee on the option to raise the OCR to 2.5%, with the decision likely going to a vote," Eckhold said.
That last point matters more than usual. Wednesday's statement will be the first under the Reserve Bank's new transparency regime to disclose individual Committee member votes when members fail to reach consensus. Until now, dissent has been invisible to the public. If the vote does break down, mortgage holders and businesses will get their first real look at how divided the Committee is on whether the Iran fuel pulse is a transient supply shock or the start of something stickier.
Kiwibank chief economist Jarrod Kerr is at the dovish end of the panel and is openly hoping the Committee sees through the oil noise. "We can only hope they remain cautious and willing to wait, worry and watch," Kerr wrote in his preview, arguing that with non tradeable inflation still trending down and the labour market loosening, lifting rates into a fragile recovery would be a mistake.
Sharon Zollner sums up the dilemma facing the Committee in one line. "Oil shocks put monetary policy between a rock and a hard place," she wrote, noting that flexibility around the timing of any move is now "very valuable".
The wider New Zealand economy is still finding its footing. Retail sales lifted 2.2 percent in the March quarter to 32 billion dollars, the best reading in two years, but the gains were heavily concentrated in supermarkets and accommodation rather than discretionary categories like clothing and electronics. The housing market remains soft, with almost one in five townhouses now selling for less than the previous owner paid, and unemployment is forecast to stay near five percent for most of 2026.
That mix gives the Committee a tactical reason to wait. If the oil price unwinds quickly once the immediate phase of the Iran conflict eases, headline inflation should fall back inside the band without any tightening at all. If oil stays high, the Committee will have plenty of opportunity to lift rates at the next review on 9 July, when it will also have a fresh Monetary Policy Statement and updated forecasts to anchor the move.
For mortgage holders the practical message is that the recent run of falls in two year fixed rates has likely come to an end. Westpac lifted its two year carded rate this week and other banks are expected to follow, even before the Reserve Bank moves, as wholesale rates price in the chance of a hike later in the year. Anyone refixing in the next month should plan around the possibility that the cheapest rate on offer today will not be there in August.
