Question

Six frontier AI models put this at 32% by 13 Nov 2026. Full reasoning from every model.

WillHappen.ai · Accepted Answer

32% — the median of 6 frontier models, resolving by 2026-11-13.

Answer

Gemini (Google): 32% — Hikes coincide with quarterly Outlook meetings like October, but the Policy Board typically prefers waiting for spring wage clarity. Governor Ueda updates growth and price projections on 29 October, making this meeting structurally viable for policy adjustments. The BOJ raises rates infrequently, historically spacing moves by several quarters to monitor yen volatility and consumption trends. A sharper yen depreciation past 155 per dollar before 28 October would most rapidly push the board toward an immediate hike.

Answer

Claude (Anthropic): 32% — Hinges on whether BOJ hikes again at October meeting after prior tightening, inflation trajectory, and yen moves into autumn 2026. BOJ has moved cautiously, often pausing between hikes to assess data, and October meetings historically see mixed outcomes versus January/July moves. Elevated inflation and yen weakness argue for continued normalization, but BOJ typically prefers clear signaling via governor speeches before acting. Absent strong forward guidance already priced by markets as of mid-October 2026, a surprise hike this specific meeting is less likely than a hold with hawkish tilt.

Answer

GPT (OpenAI): 37% — It turns chiefly on whether wage and inflation data persuade the nine-member board to tighten before fiscal-year-end. The Policy Board must approve a change on 29 October; no parliamentary or external legal clearance is required. BOJ tightening has been gradual, and meeting-to-meeting hikes are uncommon unless inflation and wage momentum materially surprise higher. A sharp yen fall or an upside Tokyo CPI/wage release before 29 October would raise the odds; weak activity would favor a hold.

Answer

Grok (xAI): 32% — Whether late-Oct CPI/wages still show inflation sticky above 2% with a stable yen. Ueda's board votes 29 Oct after 24 Oct CPI; they need two consecutive above-target prints plus no yen spike. Since NIRP exit BOJ hiked in ~1 in 4 meetings; this sits near that base as they often skip after a prior move. A sub-1.8% core CPI or GDP contraction would most shift them to hold.

Answer

DeepSeek (DeepSeek): 24% — The BOJ lacks a quarterly forecast round and faces political pressure, making an off-cycle October hike against its recent cautious pattern. Base rate since 2024 is two hikes per year (March 2024, July 2024, January 2025), but the BOJ has grown cautious amid US tariff risk and political pressure. The 28-29 October meeting is not a quarterly Outlook Report meeting, and the BOJ historically prefers to move when it publishes fresh projections. Ueda has signaled readiness to hike if inflation runs hot, so a stronger-than-expected September CPI (17 October) or yen weakness above 155 could force a move.

Answer

Qwen (Alibaba): 38% — BOJ's cautious cadence means a hike at any single meeting is a minority outcome, even in a tightening cycle. BOJ has historically paused 2-3 meetings between hikes; from Jan 2025's 0.5%, they likely hit 0.75-1.0% by mid-2026, making Oct a possible but not certain next step. Elevated inflation supports continued normalization, but the BOJ typically waits for Tankan and wage data confirmation, which often delays action to December or January… A sharp yen decline or upside inflation surprise in Q3 2026 would push this above 50%; a global slowdown or domestic demand weakness would cut it below 20.
