New Zealand central bank signals next rate hike likely in December

This week's hike, the RBNZ's second straight, was widely expected. The tone of the accompanying statement was the element that moved markets more, as investors read it as delaying the next move to December rather than October. Swaps pricing now reflects a 31% chance of a hike in October and effective certainty of one by December. That repricing indicates a central bank still intent on further tightening but signaling it needs more time to evaluate the impact of hikes already made. For the kiwi dollar, the near-term read is a lack of a fresh hawkish catalyst, since the committee's own framing argues against seeing October as a live meeting, even as the medium-term tightening bias persists.

The RBNZ's second consecutive rate increase this week included a hint that the next move is more likely to occur in two meetings rather than one.

Summary: According to Bloomberg (gated), citing an interview with RBNZ Assistant Governor Karen Silk:

• The RBNZ increased the Official Cash Rate for the second meeting in a row this week. Governor Anna Breman stated that another rate rise is probable, but officials need time to evaluate the effect of the increases already made.
• The statement's tone caused investors to reduce the likelihood of an October hike and to price in a move at the December meeting instead.
• Swaps data indicate only a 31% chance of a quarter-point increase to 3% in October, compared with near certainty (100%) that such a move will occur by December.
• Silk noted that the rate trajectory points to December being more probable than October, but she emphasized that the RBNZ is not following a fixed path and will adjust if data or conditions change.
• The RBNZ now projects that headline inflation, currently seen at 3.9% by end-2026, will not reach the 2% midpoint of its 1-3% target range until early 2028, later than earlier forecasts.
• Silk was among four of the six MPC members who identified upside inflation risks, including potential pass-through from Middle East-driven fuel and freight costs, firms using the recovery to increase prices, and persistent non-tradable inflation in sectors such as insurance and electricity.

New Zealand's central bank raised the Official Cash Rate for the second straight meeting this week. However, investors now expect the next increase in December rather than October, according to Bloomberg, which spoke with RBNZ Assistant Governor Karen Silk in Wellington on Friday.

After the decision, Governor Anna Breman said another rate increase is likely, but policymakers need time to see how earlier hikes are transmitting through the economy. This language significantly altered market expectations: swaps data show just a 31% chance of a quarter-point rise to 3% at the October meeting, versus near-certainty that such a move will have been delivered by December. Silk told Bloomberg that the committee made clear further tightening is likely, subject to the outlook, and while the timing is not fixed, the current path makes December "more likely than" October.

Silk was cautious to present that leaning as a product of the current data path rather than a fixed commitment, stating that the RBNZ must "think flexibly" and adjust if new data or circumstances shift.

The decision coincides with the RBNZ revising its inflation timeline. The bank now anticipates slightly faster inflation through 2027 and no longer forecasts headline inflation returning to the 2% midpoint of its 1-3% target band until early 2028, later than earlier estimates. At the same time, the central bank is monitoring a recovery it views as uneven: exports and tourism are leading, while household spending and investment remain subdued. Silk described the situation as a delicate balance between fostering that recovery and protecting against inflation, saying policymakers are considering how much tightening to implement now versus the risk of having to do more, and faster, later.

Silk was one of four on the six-member Monetary Policy Committee who highlighted upside risks to the inflation outlook, which currently shows inflation staying at 3.9% through end-2026 before falling to 2.1% a year later. She pointed to three specific risks: the possibility that the Middle East conflict persists and transmits into fuel prices, freight costs, and other second-round effects; the risk that firms use the economic recovery as a pretext to raise prices; and the persistence of non-tradable domestic inflation in areas where the RBNZ has little influence, such as insurance, electricity, and land taxes. Despite these risks, the committee did not require a formal vote for this week's decision, and Silk said she did not deem the risks strong enough to justify a dissenting view.
