Recent inflation data showing a June 2026 spike to 4.1% year-over-year, driven by higher fuel prices and a weaker New Zealand dollar, has reinforced expectations for further tightening by the Reserve Bank of New Zealand. With the OCR already lifted 25 basis points to 2.75% in September, trader consensus on Polymarket assigns a 59.5% implied probability to another 25 basis point increase at the December Monetary Policy Statement, reflecting the central bank's data-dependent stance and modeled OCR track signaling gradual removal of accommodation. Recent comments from Chief Economist Paul Conway highlight optionality around the late-October review amid persistent price pressures, while most bank forecasts anticipate a pause then followed by a December hike toward 3%. Core measures and labor market conditions continue to support the medium-term return to the 1-3% target band.
