The Reserve Bank of New Zealand raises interest rates this week.

Question

Six frontier AI models put this at 35% by 4 Nov 2026. Full reasoning from every model.

WillHappen.ai · Accepted Answer

35% — the median of 6 frontier models, resolving by 2026-11-04.

Answer

Gemini (Google): 37% — The decision turns on whether Q3 non-tradable inflation surprised high enough to force an immediate hike over holding. The RBNZ Monetary Policy Committee meets this week facing sticky services inflation against rapidly cooling broader demand. Central banks rarely hike when markets price under a 50% chance unless forward guidance explicitly signaled urgency. A hold remains the lower-friction default while the MPC assesses the lagged transmission of prior restrictive settings.

Answer

Claude (Anthropic): 8% — RBNZ's easing cycle and weak NZ growth make a hike this week highly unlikely despite market chatter. NZ inflation has been near target and the OCR has been on a cutting path through 2024-2025, so a reversal to hiking lacks clear justification. Markets pricing in 'potential' hike often reflects tail-risk hedging rather than a base case, and RBNZ communications have leaned dovish-to-neutral. A hawkish surprise would require a sharp inflation upside shock or currency crisis in the days before the meeting, which hasn't been signaled.

Answer

GPT (OpenAI): 22% — It hinges on whether inflation and expectations force the MPC to override a likely hold bias at its 4 November meeting. The RBNZ Monetary Policy Committee must vote for an OCR increase on 4 November, leaving no second decision window. Central banks rarely hike without a clear upside inflation surprise; a 25bp hike being merely 'on the table' implies it is not consensus. A fresh CPI or wage shock, or materially unanchored inflation expectations before the meeting, would sharply raise the odds.

Answer

Grok (xAI): 42% — Whether the OCR is hiked at this week's scheduled RBNZ decision. RBNZ meets ~8 times a year; hikes occur in under a quarter of meetings even inside tightening cycles. A 25 bp move requires inflation and labour data already showing overheating by the 28 Oct–4 Nov window. A hotter-than-expected CPI print in the days before the announcement would most shift the odds.

Answer

DeepSeek (DeepSeek): 62% — It hinges on whether the RBNZ's November 2026 statement treats a 25bp hike as needed insurance against sticky inflation. The Monetary Policy Committee meets Wednesday 4 Nov 2026 and its own prior guidance flags a possible hike, so the decision is live rather than a tail. Markets pricing a 25bp move means the hurdle is clearing the Committee's inflation-forecast threshold, not persuading a reluctant bank. Base rate for RBNZ hikes at meetings where markets price >50% is roughly 60-70%, and this sits mid-range given recent CPI prints.

Answer

Qwen (Alibaba): 33% — RBNZ hiking from an easing cycle requires a sharp inflation reacceleration signal that markets haven't fully priced. Markets pricing a hike as 'on the table' rather than consensus suggests roughly 25-35% implied probability in swaps. RBNZ historically prefers to signal before acting; an unpriced hike would require a data shock between the last MPS and this meeting. A surprise upside CPI or employment print in the prior two weeks would be the main catalyst to push this over 50%.
