Bank of Japan October 2026 Meeting
The official two-day schedule, the post-July policy baseline, the verified October rate-market structure, settlement rules, and research checkpoints before the decision.
Published September 9, 2026 · Meeting: October 29–30, 2026 · Next planned refresh: October 15, 2026, plus an immediate rebase after the September 17–18 decision
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 at publication is the guideline for the uncollateralized overnight call rate at around 1.0%, set on June 16 and held by an 8–1 vote on July 31. One decision now sits between this page and its target: the September 17–18 meeting, whose outcome will set the rate level immediately before October. An exact Polymarket event for the October decision was active and open in the September 9 research check at 14:06 UTC, with about $76,684 in cumulative volume, roughly $15,609 in displayed liquidity, and five possible change buckets. In that snapshot the no-change contract showed a displayed YES price of 82¢ (bid 81¢ / ask 83¢) against 18¢ 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 1.0% baseline is official
The Bank raised the uncollateralized overnight call rate guideline to around 1.0% on June 16, effective June 17, and the July 31 statement kept that guideline for the next intermeeting period by an 8–1 vote. That July decision is the latest completed policy record at publication.
September comes first
The September 17–18 Monetary Policy Meeting is still pending as this hub is published. The October contract does not ask about September; it compares the specified rate immediately before the October meeting with the change that meeting causes, so the September outcome will simply rebase the starting level.
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.
This decision is the immediate catalyst between publication and the target meeting. Once the statement is out, this guide will be rebased immediately: new level, fresh snapshot, and updated before-and-after framing for October.
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 14:06 UTC on September 9, its top-level event was active and not closed, with about $76,684 in cumulative volume, roughly $15,609 in displayed liquidity, and about $2,017 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.

| Bucket | YES | Bid / Ask | Contract volume |
|---|---|---|---|
| No change | 82¢ | 81¢ / 83¢ | $31,747 |
| +25 bps | 18¢ | 17¢ / 19¢ | $27,855 |
| +50+ bps | 0.45¢ | 0.4¢ / 0.5¢ | $7,157 |
| −25 bps | 0.15¢ | — / 0.3¢ | $6,079 |
| −50+ bps | 0.05¢ | — / 0.1¢ | $3,845 |
Read the table as one timestamped research artifact, not a forecast: displayed YES prices sum to about 100.65% 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—carry nearly identical contract volume, which 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 1.0% post-July baseline—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
Whatever the September 17–18 meeting decides, the October market restarts from the level immediately before October 29. A September hike makes "no change" describe the post-hike level; it does 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.
Why search demand should rise before October 29
This hub lands 50 days before the meeting, inside the standard 21–75 day proactive window: early enough to be crawled and ranked before date-specific intent concentrates, without sitting so far out that the calendar could change underneath it. The topic was selected because the Bank's annual calendar fixes the date with certainty and a dedicated five-outcome event is already live—not because any particular outcome looks likely today.
Post-September "what's next" wave
Once the September 17–18 decision is out, October 29–30 becomes the next scheduled Monetary Policy Meeting. "Next Bank of Japan meeting" intent has to land somewhere; this canonical and the September guide split the two meetings cleanly by date.
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.
Refresh the baseline twice
Record the post-July 1.0% guideline now, then re-check after September 17–18. The level immediately before the October meeting—not either snapshot—is what the 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, 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 July 31, 2026, the Policy Board voted 8–1 to keep the guideline for the uncollateralized overnight call rate at around 1.0%, defeating Hajime Takata's 1.25% proposal. The September 17–18 decision comes before the October meeting, so the level immediately before October depends on that pending decision.
Are there active Bank of Japan October 2026 prediction markets?
Yes. The exact Polymarket event checked September 9, 2026 at 14:06 UTC was active and open with five rate-change outcome contracts, about $76,684 in cumulative volume, and a displayed 82¢ YES price for no change against 18¢ for a 25-basis-point increase at that timestamp.
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?
An immediate rebase will follow the September 17–18 decision, a planned pre-meeting refresh is set for October 15, 2026, and a decision-day update will follow the October 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.
