The answer first
The next Bank of England interest rate decision is scheduled for Thursday, September 17, 2026. The Monetary Policy Committee is due to announce Bank Rate and publish its September summary and minutes that day. The official rate remained 3.75% when checked August 6, after a 6–3 vote to hold on July 30. The exact September Polymarket event was also active and open in the August 6 check, with five Bank Rate change buckets, about $134,661 in cumulative volume, $3,414 in 24-hour volume, and $24,981 in liquidity. The outcome is unknown. This guide separates the confirmed date and current rate from changing market prices, forecasts, and the written rules that control resolution.
Next Bank of England decision: date, baseline and scope
Thursday, September 17, 2026
The Bank's official rate page and MPC calendar both identify September 17 as the next due date. The calendar pairs the decision with publication of the September MPC summary and minutes.
Current Bank Rate: 3.75%
The official July summary records a 6–3 vote to maintain Bank Rate at 3.75%. That is the confirmed post-July context, not a prediction of the September decision.
Five outcome markets
The exact event covers a decrease of at least 50 basis points, a 25-point decrease, no change, a 25-point increase, and an increase of at least 50 points.
$134.7K cumulative volume
At 14:05 UTC on August 6, the active event showed about $134,661 cumulative volume, $3,414 in 24-hour volume, and $24,981 liquidity. Prices are omitted because they change quickly.
A date-first search can hide four different questions: when the committee announces, what Bank Rate is now, what documents appear with the decision, and how a prediction market classifies the move. This page answers each separately so an official date is not mistaken for an outcome forecast, and a market end time or last trade is not mistaken for the Bank's own calendar.
Official Bank of England September 2026 timeline
The July Monetary Policy Summary records a 6–3 vote to maintain Bank Rate at 3.75%. Three members preferred an increase to 4%. The Bank's rate page was updated the same day and named September 17 as the next due date.
The official calendar still named September 17, the rate page still showed 3.75%, and the exact five-contract event remained active, not closed, and accepting orders. The event-level snapshot showed about $134,661 cumulative volume, $3,414 in 24-hour volume, and $24,981 liquidity at 14:05 UTC.
New inflation, pay, employment, activity, and financial-condition evidence can change expectations before the next meeting. Those releases may move forecasts and order books, but none substitutes for the official September MPC announcement as the reviewed market's resolution evidence.
This page will recheck the official calendar and Bank Rate, the full five-market inventory, active/closed status, and the exact resolution wording about rounding, postponement, cancellation, and emergency moves. A material source change triggers an earlier refresh.
The Bank of England calendar schedules the September MPC summary and minutes for this Thursday. The reviewed prediction-market rules measure the change in Bank Rate caused by this specified meeting relative to the level immediately before it.
This later date matters to the September event's postponement clause. If the specified meeting is cancelled, or delayed so no decision is announced before the next scheduled meeting begins, the reviewed rules assign the no-change bracket.
What the verified September Polymarket event covers
The exact public event reviewed for this guide is titled Bank of England decision in September? At 14:05 UTC on August 6, its top-level event was active and not closed, and every component market was active, open, and accepting orders. Event-level demand cleared this project's provisional publication floor: about $134,661 in cumulative volume, $3,414 in 24-hour volume, and $24,981 in liquidity. The refresh found the same five outcome questions and the same meeting-specific resolution framework:
50+ bps decrease
A Bank Rate decrease that the event classifies in its 50-basis-point-or-larger bucket after applying the written rounding rules.
25 bps decrease
A smaller qualifying decrease classified as 25 basis points. One basis point is 0.01 percentage point, so 25 basis points equals 0.25 percentage point.
No change
No qualifying change in Bank Rate resulting from the specified September meeting, including the cancellation or long-postponement fallback described by the event.
25 bps increase
A qualifying increase classified as 25 basis points under the same meeting boundary and rounding method.
50+ bps increase
A Bank Rate increase placed in the 50-basis-point-or-larger bucket after the contract's classification rules are applied.
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 can differ.
The event is narrower than a generic question about the UK economy, the July vote split, or where Bank Rate will finish the year. It names one MPC meeting, one official policy rate, one before-and-after comparison, and one source hierarchy. The July hold does not resolve or mechanically determine any September bucket. That distinction is the main reason a meeting guide is useful: similar-looking rate questions can settle on different dates, baselines, or definitions.
Bank Rate market resolution: seven rules that matter
1. Bank Rate is the unit
The event measures the change in the Bank of England's Bank Rate. The Bank explains that this rate influences the borrowing and savings rates offered by commercial banks and other institutions.
2. Compare immediately before and after
Resolution uses the change produced by the September meeting relative to the level before that meeting. The confirmed 3.75% post-July rate is current context, not an irrevocably fixed settlement baseline.
3. Use the upper bound if needed
The rules say that if the specified rate is expressed as an upper and lower bound, the relevant change is the change to the upper bound. That clause prevents a range from creating an undefined comparison.
4. Small moves round to 25
An increase or decrease smaller than 25 basis points is treated as a 25-basis-point move. Under the reviewed wording, a 10-basis-point change does not become “no change.”
5. Larger moves use nearest-25 rounding
Changes larger than 25 basis points are rounded to the nearest 25. An exact tie is rounded away from zero, so a 37.5-basis-point move is classified as 50 basis points.
6. Official information controls
The event names official Bank of England information, including the statement or release from the September meeting. Surveys, commentary, futures, and press reports can inform expectations but are not the named settlement source.
7. Emergency and schedule clauses differ
Emergency changes not resulting from the specified meeting are excluded. A postponed meeting counts if it occurs before the next scheduled meeting; cancellation or a longer delay falls to no change under the reviewed rules.
Save the current wording
A reproducible research record includes the exact question, description, source link, active/closed status, and timestamp. A screenshot of one price does not preserve the rules.
Why search demand should rise before September 17
This canonical page is substantially refreshed 42 days before the scheduled decision so search engines have time to recrawl one durable URL before the meeting-date and outcome-intent wave. The refresh is tied to measurable early demand, not a generic news cycle: the exact query next bank of england interest rate decision date produced 51 impressions at average position 1.0 in the latest seven-day Search Console window, while the July decision established the post-meeting baseline and the exact September event remained live.
Post-July baseline wave
With the 3.75% hold and 6–3 vote confirmed, users can shift from “what did the Bank do in July?” to “when is the next Bank of England meeting?” and “what could happen in September?” This refresh answers that handoff without creating a competing URL.
Late-summer evidence wave
As new UK economic evidence arrives, attention can move from the calendar toward the five outcome buckets and the committee's next decision. This guide keeps official facts, market mechanics, and changing forecasts separate.
Decision-week wave
Intent should become most specific around the announcement time, minutes, market status, and settlement evidence. A final pre-meeting review will remove stale status language; a post-event update can preserve the confirmed outcome on the same canonical page.
Research workflow for the September Bank of England decision
Start with the official calendar
Verify September 17 on the Bank of England site. Do not infer the meeting date from a market end time, an unaffiliated economic calendar, or a social post.
Refresh the policy baseline
The July summary and official rate page now confirm 3.75%. Before September, check that page again and record the rate in force; keep it distinct from a forecast and from the change caused by the September meeting.
Read all five questions
Confirm that every outcome carries the same meeting, rate, source, rounding, postponement, and emergency-action language. One short outcome label cannot describe the complete event.
Measure the order books
Use the prediction-market odds guide to record spread and depth rather than treating the last trade as an exact probability. Separate binaries can contain apparent gaps.
Compare institutions carefully
The September ECB guide, September Fed guide, September Bank of Canada guide, and September Bank of Japan guide cover different dates, policy rates, committees, and rule sets. A move in one market does not mechanically determine another.
Separate context from settlement
The U.S. CPI calendar and U.S. jobs calendar can help map global macro attention, but neither is the BoE market's named resolution source.
Investigate sudden moves
The biggest-movers watchlist can flag a contract for review. It cannot establish whether a move reflects evidence, thin liquidity, or a single order.
Keep probability claims bounded
The prediction-market accuracy guide explains why a quoted probability is evidence to assess, not certainty. No rate bucket or return is guaranteed.

Which interest rate resolves the September Bank of England market?
The reviewed event uses the change in Bank Rate resulting from the specified September Monetary Policy Committee meeting, relative to its level immediately before that meeting. Official Bank of England information is the named resolution source.

When will this Bank of England September 2026 guide be refreshed?
The next planned review is August 24, 2026, about three and a half weeks before the decision. The page will be refreshed sooner if the official calendar, Bank Rate, market status, or written resolution rules change materially.
