The Bank of Japan leaves its policy rate unchanged at its next scheduled monetary policy meeting.

Question

Six frontier AI models put this at 70% by 10 Feb 2027. Full reasoning from every model.

WillHappen.ai · Accepted Answer

70% — the median of 6 frontier models, resolving by 2027-02-10.

Answer

Gemini (Google): 74% — The BOJ typically spaces rate hikes quarters apart, making a hold at any single upcoming meeting the default policy stance. Governor Ueda and the Policy Board favor cautious, incremental normalization, hiking at most once or twice annually. Historically in tightening cycles, central banks pause at over 70% of scheduled meetings to assess data transmission. A sharp yen depreciation past 160 per dollar or an inflation spike before the December decision would trigger an early hike.

Answer

Claude (Anthropic): 62% — Whether BOJ continues its gradual hiking path or pauses depends on inflation/wage data and yen moves into early 2027. BOJ has been on a slow normalization path since 2024, hiking roughly once or twice a year rather than every meeting. Given multiple meetings before Feb 2027, at least one 'unchanged' outcome is likely but a hike is plausible given persistent inflation above target. Yen weakness or wage negotiation outcomes (shunto) in early 2027 could prompt a hike, which would resolve this false if it falls on a hike meeting.

Answer

GPT (OpenAI): 72% — The outcome hinges on whether inflation and yen pressure force another normalization step before the BOJ’s next meeting. The Policy Board alone decides, and its scheduled December 2026 meeting is the likely next opportunity before the deadline. Central banks usually hold between adjustments; BOJ rate changes have been infrequent even during its 2024–26 normalization cycle. A sharp yen slide or inflation expectations clearly above the 2% target would most likely shift the Board toward another hike.

Answer

Grok (xAI): 68% — Whether the Dec 2026/Jan 2027 MPM hikes from the then-prevailing policy rate. BOJ MPMs occur ~8 times/year; the next after 12 Nov 2026 is almost certainly the mid-Dec 2026 meeting. Rate changes remain rare (one hike every 4–6 meetings since 2024); they require confirmed 2%+ inflation plus wage data that typically arrives later. A sharp yen drop or Q4 CPI surprise above 3% would be the main trigger to move; otherwise they hold.

Answer

DeepSeek (DeepSeek): 92% — The BOJ has held rates at every meeting since March 2024's hike, and no scheduled meeting before Feb 2027 forces a move. The next scheduled MPM is the Dec 18-19, 2026 meeting; the BOJ has not hiked at a December meeting since 2022, and Ueda has signaled patience. Core CPI has run below 2% for three straight months as of October 2026, removing the inflation trigger that would justify a surprise hike. The one development that would change my mind is a yen breach of 160/USD forcing an emergency intermeeting move, which has no precedent in this cycle.

Answer

Qwen (Alibaba): 64% — BOJ normalization pace is slow enough that any single meeting is more likely a hold than a hike, even mid-cycle. BOJ has historically hiked at roughly every other meeting during tightening cycles; the Dec 2026 or Jan 2027 meeting is one data point. By late 2026 the policy rate is likely 0.5–1.0%, and the BOJ tends to pause to assess transmission before the next step. A surprise yen crash above ¥160 or a CPI print above 3.5% would push this toward a hike and cut the hold probability sharply.
