Bank of Japan October 2026 Decision: Pause Favored After September Hike
The official October 29–30 dates, the post-September 1.25% baseline, the verified five-outcome Polymarket event with a pause priced at 81.5¢, settlement rules, and the research checkpoints before the October 30 statement.

The answer first
The Bank of Japan's October 2026 Monetary Policy Meeting is scheduled for Thursday and Friday, October 29–30, with the Statement on Monetary Policy and The Bank's View of the Outlook Report due on October 30, the Summary of Opinions on November 10, and the minutes on December 23. The policy baseline is now the guideline for the uncollateralized overnight call rate at around 1.25%, set by the September 17–18 meeting's 7–2 vote and effective September 24 — the second hike of 2026 after June's move to 1.0%. At the September 24, 14:04 UTC check, the exact Polymarket event for the October decision was active and open with about $138,727 in cumulative volume, roughly $40,264 in displayed liquidity, and about $3,169 traded in the prior 24 hours. In that snapshot the no-change contract showed a displayed YES price of 81.5¢ (bid 81¢ / ask 82¢) against 18.5¢ for a 25-basis-point increase. The October outcome is unknown. This guide does not freeze a fast-moving price or forecast the decision; it maps the verified dates, the baseline, the measured rate, and the edge-case rules that control resolution.
Where the October meeting sits in the 2026 calendar
The 1.25% baseline is official
The Bank raised the uncollateralized overnight call rate guideline to around 1.0% on June 16 and to around 1.25% on September 18 by a 7–2 vote, effective September 24. The complementary deposit facility rate moved to 1.25% and the basic loan rate to 1.5%.
September has decided
The September 17–18 meeting raised the rate to around 1.25%, and its Polymarket event settled the 25-basis-point increase bucket to Yes at $1.00. The October contract now measures from the new level — a September hike does not pre-resolve the October bracket.
An Outlook Report lands with October
Unlike the September meeting, the official calendar attaches an Outlook Report to the October 29–30 meeting: The Bank's View is due October 30 alongside the statement, with the full text following at 2:00 p.m. on the next business day. Projections arrive with this decision, not weeks later.
One decision, five buckets
The reviewed event splits the October outcome into five brackets: a decrease of at least 50 basis points, a 25-basis-point decrease, no change, a 25-basis-point increase, and an increase of at least 50 basis points. Each bracket is a separate yes/no order book.
Official Bank of Japan October 2026 timeline
The Policy Board voted 7–1 to encourage the uncollateralized overnight call rate to remain at around 1.0%, effective June 17. That June change explains why the identical figure in the July statement represented continuity rather than a new increase.
The July 31 statement kept the guideline around 1.0% by an 8–1 vote; Hajime Takata preferred 1.25% and was defeated. An Outlook Report accompanied this meeting, making it the most recent full quarterly-policy occasion before autumn.
Published at 8:50 a.m. JST as scheduled, it shows a Board balancing patience with further tightening: some members stressed the roughly one-to-one-and-a-half-year lag before a hike's effects fully emerge, while others argued for continuing to raise the policy rate, with price risks skewed to the upside.
The hub lands 50 days before the meeting: early enough for search engines to crawl a stable canonical before October attention builds, and before the September decision reshapes the baseline the October market measures from.
The Policy Board voted 7–2 to raise the guideline for the uncollateralized overnight call rate to around 1.25%, effective September 24; Asada Toichiro and Sato Ayano dissented, preferring to keep policy unchanged, and the decision reference is timestamped 11:54 a.m. The statement said the Bank “will continue to raise the policy interest rate.” The September Polymarket event settled its 25-basis-point increase bucket to Yes at $1.00; the September guide records the full decision and settlement.
Six days after the decision, this page records the new baseline, the settled September outcome, and a fresh October snapshot: cumulative event volume up about 81% since the September 9 publication to $138,727, with no change still priced well above another hike (81.5¢ vs 18.5¢). Next checkpoints: the October 1 Summary of Opinions and the October 15 pre-meeting refresh.
Scheduled for 8:50 a.m., it documents the range of Board views behind the September decision—useful context for reading the October board, but not the October settlement evidence.
Two weeks before the meeting—when central-bank search attention historically starts building—this guide will re-verify the calendar, refresh the five-bucket snapshot, and clear stale status language.
The Bank schedules this meeting across Thursday and Friday. The Statement on Monetary Policy and The Bank's View of the Outlook Report are due October 30; the full Outlook text follows at 2:00 p.m. on the next business day. The reviewed market may resolve as soon as the statement with relevant data is issued.
The official calendar schedules this release for 8:50 a.m. Like the statement, it is an official document, but the market is expected to settle from the October statement rather than wait for it.
This meeting matters to the postponement clause: if no statement for October is released by the end date of this next meeting, the reviewed rules assign the no-change bracket. The October minutes follow on December 23.
What the verified October Polymarket event covers
The exact event reviewed for this guide is titled Bank of Japan Decision in October? At 14:04:58 UTC on September 24 — the rebase snapshot — its top-level event was active and not closed, with about $138,727 in cumulative volume, roughly $40,264 in displayed liquidity, and about $3,169 traded in the prior 24 hours. All five component questions were active and accepting orders. The durable structure is the set of resolution buckets and the exact question labels:
50+ bps decrease
"Bank of Japan decreases interest rates by 50+ bps after the October 2026 meeting?"—a decrease large enough for the 50-basis-point-or-larger bracket after the written rounding method.
25 bps decrease
"Bank of Japan decreases interest rates by 25 bps after the October 2026 meeting?"—a smaller qualifying decrease classified as 25 basis points. One basis point is 0.01 percentage point.
No change
"No change in Bank of Japan's interest rates after the October 2026 meeting?"—no qualifying change resulting from the meeting, including the no-statement fallback in the reviewed rules.
25 bps increase
"Bank of Japan increases interest rates by 25 bps after the October 2026 meeting?"—a qualifying increase classified as 25 basis points under the meeting boundary and rounding method.
50+ bps increase
"Bank of Japan increases interest rates by 50+ bps after the October 2026 meeting?"—an increase placed in the 50-basis-point-or-larger bracket after classification.
Five binaries, one decision
Each outcome is a separate yes/no order book. Displayed YES prices may not add to exactly 100% because spreads, depth, timing, and independent orders differ across books.
This event is narrower than a general question about Japanese interest rates or where policy finishes in 2026. It names one two-day meeting, one short-term rate's upper bound, one before-and-after comparison, and a defined source hierarchy. That distinction prevents similar-looking central-bank markets from being treated as interchangeable.
September 24 snapshot (14:04:58 UTC)
$138,727
cumulative event volume at the snapshot timestamp — up about 81% from $76,684 at the September 9 publication check, from a $0 base when the event was created on July 31, 2026.
$40,264
displayed liquidity across the five order books at the same timestamp, up from about $15,609 at the publication check.
$3,169
traded in the 24 hours before the snapshot, up from about $2,017 at the publication check.
| Bucket | YES | Bid / Ask | Contract volume |
|---|---|---|---|
| No change | 81.5¢ | 81¢ / 82¢ | $45,177 |
| +25 bps | 18.5¢ | 18¢ / 19¢ | $48,948 |
| +50+ bps | 1.4¢ | 0.9¢ / 1.9¢ | $25,403 |
| −25 bps | 0.05¢ | — / 0.1¢ | $12,159 |
| −50+ bps | 0.05¢ | — / 0.1¢ | $7,041 |
Read the table as one timestamped research artifact, not a forecast: displayed YES prices sum to about 101.5% because five independent order books carry their own spreads and depth, volume measures attention rather than probability, and any number here may be stale minutes later. The two most-traded buckets—no change and a 25-basis-point increase—now hold the two largest books, with the increase book slightly ahead in volume; that balance is why this guide tracks both rather than declaring a favorite.
Bank of Japan October market resolution: eight rules that matter
1. The upper bound is the measured rate
The October event resolves to the change in the upper bound of the short-term policy interest rate. Commentary about yields, inflation, bond purchases, or the yen does not by itself answer that precise contract question.
2. Compare immediately before and after
Resolution uses the change versus the level prior to the Bank of Japan's October 2026 meeting. A level observed weeks earlier—including this page's recorded 1.0% and 1.25% baselines—is context, not a fixed settlement level.
3. Odd-sized moves round up
If the rate moves to a level not expressed in the displayed options, the change is rounded up to the nearest 25 basis points: the contract's own example says a 12.5-basis-point cut or increase counts as 25. Note this October wording differs from the September event, which rounds to the nearest 25 with ties away from zero.
4. Official source first, reporting fallback
The primary resolution source is the official Bank of Japan website; the October wording adds that a consensus of credible reporting may also be used. The September contract names official Bank of Japan information—another reason not to treat the two pages' rules as identical.
5. Resolution can arrive with the statement
The market may resolve as soon as the Bank of Japan's October statement with relevant data is issued—scheduled for October 30. Waiting for the Summary of Opinions or minutes is a research habit, not a settlement requirement.
6. The no-statement fallback is dated
If no statement is released by the end date of the next scheduled meeting—December 17–18, 2026—the market resolves to the no-change bracket. That is a written boundary, not an assumption about postponements.
7. Emergency actions sit outside
The contract measures the change resulting from the specified October meeting. An extraordinary action between meetings is not the reviewed question, even if it moves the rate the market watches.
8. September is not the October question
The September 17–18 meeting raised the rate, and the October market restarts from the level immediately before October 29. That makes "no change" describe holding the new 1.25% level; the September hike did not pre-resolve the October bracket.
A reproducible research note preserves the exact event slug, all five question labels, the complete description, source links, active/closed status, and check time. A screenshot of one price does not preserve the rate definition, the rounding method, or the fallback boundaries.
What changed since the September 9 publication
The baseline reset. This guide launched against the 1.0% guideline set on June 16 and held by an 8–1 vote on July 31. On September 18 the Policy Board raised the guideline to around 1.25% by a 7–2 vote — the second hike of 2026 — effective September 24, with the complementary deposit facility at 1.25% and the basic loan rate at 1.5%. Two members, Asada Toichiro and Sato Ayano, dissented in favor of no change.
The board barely moved. At publication, before the September decision, no change traded at a displayed 82¢ against 18¢ for a 25-basis-point increase. Six days after the hike — at the September 24 snapshot — the split was 81.5¢ versus 18.5¢. The market had priced September's hike as near-certain, absorbed it, and still favors a pause in October; back-to-back hikes remain the minority price.
Attention and liquidity built. Cumulative event volume grew from about $76,684 on September 9 to about $138,727 on September 24 (+81%), displayed liquidity from about $15,609 to about $40,264, and 24-hour volume from about $2,017 to about $3,169. The September companion event finished at about $1,524,646 in volume.
What did not change: the official calendar still fixes October 29–30 with the Outlook Report on October 30 (re-verified on the Bank's site on September 24), the five buckets and their round-up classification rule are unchanged, the December 17–18 no-statement fallback still stands, and the official Bank of Japan website remains the primary resolution source.
Why search demand should rise before October 29
This hub was published 50 days before the meeting and rebased 36 days out, inside the standard 21–75 day proactive window: early enough to be crawled and ranked before date-specific intent concentrates, close enough that the evidence stays current. The topic was selected because the Bank's annual calendar fixes the date with certainty and a dedicated five-outcome event is live — at the September 24 check it held about $138,727 in cumulative volume with about $3,169 in 24-hour volume, clearing the site's proactive-selection demand floor — not because any particular outcome looks likely today.
Post-September "what's next" wave
The September 18 hike has landed, so "next Bank of Japan meeting" intent now resolves to October 29–30. This canonical and the September guide split the two meetings cleanly by date: September holds the settled record, October holds the live question.
Outlook Report wave
October is a quarterly-projection meeting. The Bank's View arriving with the statement tends to generate a second round of coverage—forecasts, dissent, and the December path—that keeps the page's subject current after decision day.
Decision-week wave
Intent becomes most specific in the final days: exact dates, current market status, source hierarchy, and settlement mechanics. The October 15 refresh removes stale status language so decision-week readers see current facts, and a decision-day update preserves the confirmed result.
Research workflow for the October BOJ decision
Start with the official calendar
Verify October 29–30 on the Bank of Japan site. Do not infer the meeting date from a market end time, an unofficial economic calendar, or a social post.
Confirm the baseline from the September statement
The September 18, 2026 decision set the guideline at around 1.25%, effective September 24, with the complementary deposit facility at 1.25% and the basic loan rate at 1.5%. That official level—not a forecast—is what the October contract measures from.
Read all five questions
Confirm every outcome carries the same meeting, rate, source hierarchy, rounding, and fallback wording. One abbreviated outcome label cannot describe the complete event.
Measure the order books
Use the prediction-market odds guide to record spread and depth instead of treating the last trade as an exact probability. Separate binaries can contain apparent gaps.
Compare institutions carefully
The October Fed guide and the settled September ECB, September Bank of England, and September Bank of Canada guides cover different dates, policy rates, committees, and contract language. One decision does not mechanically determine another.
Separate context from settlement
The U.S. CPI calendar and U.S. jobs calendar help map the global macro attention cycle, but neither is the BOJ event's named resolution source.
Investigate sudden moves
The biggest-movers watchlist can flag a contract for review. It cannot establish whether a move reflects new evidence, thin liquidity, or one order.
Keep probability claims bounded
The prediction-market accuracy guide explains why a quoted probability is evidence to assess, not certainty. No outcome or return is guaranteed.
Frequently asked questions
When is the October 2026 Bank of Japan meeting?
The official Bank of Japan calendar schedules the Monetary Policy Meeting for Thursday and Friday, October 29–30, 2026. The Statement on Monetary Policy and The Bank's View of the Outlook Report are both due October 30, the Summary of Opinions November 10, and the minutes December 23.
What is the Bank of Japan's policy rate right now?
On September 18, 2026, the Policy Board voted 7–2 to raise the guideline for the uncollateralized overnight call rate to around 1.25%, effective September 24. The complementary deposit facility rate moved to 1.25% and the basic loan rate to 1.5%. Checked September 24, 2026, that is the level in force immediately before the October meeting unless an intervening official action changes it.
What did the Bank of Japan decide in September 2026?
The Bank raised the policy rate by 25 basis points to around 1.25% on September 18, 2026, by a 7–2 vote, with Asada Toichiro and Sato Ayano dissenting in favor of keeping policy unchanged. The statement said the Bank “will continue to raise the policy interest rate.” The September Polymarket event settled its 25-basis-point increase bucket to Yes at $1.00 with about $1,524,646 in final volume; the September guide records the full decision.
Are there active Bank of Japan October 2026 prediction markets?
Yes. The exact Polymarket event checked September 24, 2026 at 14:04:58 UTC was active and open with five rate-change outcome contracts, about $138,727 in cumulative volume, roughly $40,264 in displayed liquidity, and about $3,169 in 24-hour volume. At that timestamp the no-change contract displayed 81.5¢ against 18.5¢ for a 25-basis-point increase.
Which rate resolves the October Bank of Japan market?
The reviewed event measures the change in the upper bound of the short-term policy interest rate versus its level prior to the Bank of Japan's October 2026 meeting. The official Bank of Japan website is the primary resolution source.
How are unusual Bank of Japan rate changes classified in the October market?
If the short-term policy interest rate is changed to a level not expressed in the displayed options, the change is rounded up to the nearest 25 basis points. A 12.5-basis-point move would be treated as 25 basis points.
What happens if no statement is released for the October meeting?
Under the reviewed rules, if no statement is released by the end date of the next scheduled meeting—December 17–18, 2026—the market resolves to the no-change bracket.
When will this Bank of Japan October 2026 guide be refreshed?
The post-September rebase shipped September 24, 2026. A final pre-meeting refresh is planned for October 15, 2026, and a decision-day update will follow the October 30 statement. An earlier review will follow any material change to the official calendar, market status, policy baseline, or written rules.

The September 9 publication review covered the complete 124-entry blog index, all 25 existing event hubs, the 157-URL sitemap, the proactive state and refresh queue, current-day publisher output, and the latest local GSC snapshot. Exact and semantic scans confirmed that no existing page targets the Bank of Japan October 2026 meeting, its dates, or its five contracts: the September BOJ hub owns the nearer meeting, and the Federal Reserve, European Central Bank, Bank of England, and Bank of Canada pages each cover a different institution, calendar, policy rate, event ID, and primary keyword. Contextual inbound links were added from the September BOJ, October Fed, September Bank of England, and September ECB guides so the new canonical is reachable from established sibling pages. Snapshot figures were captured live from the Gamma API and re-verified in the build gate before deployment. The September 24 rebase re-verified the official calendar and both Gamma events live, re-checked the hub inventory for overlap (no other page targets the October 29–30 decision intent), and recorded the September decision and settlement as the October baseline.
