Recent inflation data showing a 4.1% annual CPI rise in the June 2026 quarter—well above the RBNZ’s 1-3% target and driven largely by tradable goods, petrol, and energy costs—has reinforced expectations for further tightening. With the Official Cash Rate already lifted 50 basis points to 2.75% in July and September, market-implied odds favor another 25 basis-point increase at the December 9 Monetary Policy Statement. Bank forecasts from ANZ, ASB, BNZ, and Westpac align with this path toward 3.00% by year-end, citing persistent price pressures and a recovering economy. The October 28 interim review is widely expected to hold steady ahead of the full projections and post-election clarity, while any moderation in upcoming CPI or activity data could support the 35.5% probability of no change.
