The floor just became a ceiling
For two years, the story was simple. The Reserve Bank cut the OCR from its 5.5% peak down to 2.25%, its lowest since 2022. Businesses refinanced, hired, and invested on the assumption that rates were heading in one direction. The May 2025 Monetary Policy Statement projected the OCR declining further to around 2.87% by June 2026.
That narrative is now breaking apart. Q4 2025 CPI hit 3.1%, breaching the RBNZ’s 1-3% target band. The bank’s own forecast for headline inflation in the July 2026 quarter is 4.2%, a full 120 basis points above the top of that band. And Governor Anna Breman has been unusually blunt: “I will not rule out either rate hikes or rate cuts because of the uncertainty in the global environment.”
That is not reassurance. That is a warning.
Domestic inflation is the real problem
If this were purely an imported energy shock, the RBNZ could look through it. But the numbers underneath are uncomfortable. Non-tradable inflation, the domestically driven component, was 3.5%. Core inflation was 2.8% with sectoral models turning upward. Two-year inflation expectations were already sitting in the upper half of the 1-3% band before the Middle East shock hit.
The composition matters for businesses. Essential goods and services inflation was running at 3.8% annually, well above its long-term average of 3.2%, while discretionary items sat at just 1.8%. As Infometrics chief executive Brad Olsen put it: “It’s essential costs that are hitting households hardest.” Wage pressure follows essential-cost inflation, not discretionary. That feeds directly into business costs.
Markets have already moved
The RBNZ held at its April 8 meeting, but markets did not wait for permission. By late March, pricing implied roughly a 60% chance of a 25 basis point hike in May, with rates fully priced for a rise by September and an endpoint of 3.0% by year end.
Bank economists have followed. ANZ pulled its first-hike forecast forward from February 2027 to December 2026. ASB is pencilling in December with a 3.0% endpoint, while flagging earlier action as a risk. Several banks have already started lifting mortgage rates without an OCR move.
The lag problem nobody wants to talk about
Here is the underappreciated risk. Rate cuts take 12 to 18 months to fully work through an economy. The RBNZ cut aggressively through 2024 and 2025, and that stimulus is still feeding into activity and inflation right now. Olsen flagged the danger directly: “You could well find yourself having a slightly hotter economic activity…and slightly hotter inflation, and then you get some further interest rate cuts that continue to fall into the economy. That could be a potent cocktail.”
ASB chief economist Nick Tuffley argues the economy has already “turned a corner”, with the PSI back in expansion, the PMI outperforming global peers, and surveys showing firmer capacity pressures. Treasury data confirms the recovery: retail sales volumes up 1.9%, residential building consents up 6.2% year-on-year, export volumes up 3.4%. A recovering economy removes the justification for emergency-low rates.
Not everyone is convinced, but even the sceptics are hedging
Kiwibank chief economist Jarrod Kerr calls the hike talk “overdone and premature”, arguing a supply shock should be looked through. Westpac’s Kelly Eckhold and Darren Gibbs say it is “unlikely the RBNZ will be raising rates in the next six months”. But even Eckhold concedes that real interest rates are “likely to be too low soon” and warns of entrenched inflation if action comes too late.
BNZ’s Stephen Toplis captured the mood best: “The spread of potential outcomes is one of the greatest that we have ever seen.”
What this means if you have debt
The practical consequences are not waiting for the RBNZ’s May decision. Banks are already repricing. The NZIER Shadow Board’s majority projection of 2.50% to 3.00% within a year implies 25 to 75 basis points of hikes. At the upper end, that is a meaningful increase in the cost of every dollar of variable-rate borrowing.
Businesses that locked in financing, made hiring decisions, or set pricing on the assumption that 2.25% was the floor now face an asymmetric risk. Rates are more likely to rise than fall, and the timeline is shorter than most planned for. Governor Breman framed the challenge herself: “Getting this judgement right is key to avoiding reacting too early to near-term inflation pressures that monetary policy can do little about, or reacting too late if above-target inflation becomes embedded in the economy.”
That is a central banker telling you, in the most diplomatic language available, that she does not know what happens next. Plan accordingly.
