ECB October 2026 Decision: A Hold at 2.50% Is Favored After the September Hike
The official October 28–29 Frankfurt calendar, the verified five-outcome Polymarket board, the resolution rules that govern settlement, and the September record that explains why a hold leads while a second consecutive hike trades close behind.
Published 2026-09-29 · Snapshot 2026-09-29 14:12:58 UTC · Next scheduled refresh: ~October 14, 2026 (after the final September euro-area inflation statistics) · Final pre-meeting refresh: October 27–28 · Decision: October 29, 2026
The answer first
The ECB's next monetary policy meeting runs Wednesday–Thursday, October 28–29, 2026 in Frankfurt, with the decision and press conference traditionally on the second day. The deposit facility rate stands at 2.50% — raised, together with the main refinancing rate (2.65%) and the marginal lending rate (2.90%), by 25 basis points at the September 9–10 Berlin meeting and effective since September 16, per the official key-interest-rate table verified on this page's publication day. Polymarket's five-outcome market for the meeting prices no change at 77.5¢ against 22.5¢ for a 25-basis-point increase to 2.75% as of the 2026-09-29 14:12:58 UTC snapshot below, with cumulative event volume at $240,081 and $41,143 of liquidity — the crowd leans toward a pause six weeks after the September hike while keeping a real second-hike tail. The market settles on the change in the deposit facility rate that the October meeting produces relative to its level before the meeting, using official ECB information, and it can resolve as soon as the statement or release is issued. A price is crowd sentiment, not the official outcome.
Where the October meeting sits in the 2026 calendar
The 2.50% baseline is official
The ECB's key-interest-rate page lists the deposit facility rate at 2.50% as of September 16, 2026 — the level the October contracts measure against, unless the Governing Council moves before then, which its published schedule does not provide for.
September has decided
The September 9–10 Berlin meeting raised all three key rates by 25 basis points, and the settled Polymarket event resolved its increase bucket to Yes. The September decision hub holds the full settled record, including the post-decision snapshot and settlement history.
A two-day Governing Council week
October 28–29 is the fifth monetary policy meeting of 2026. The published calendar also lists non-monetary meetings on September 30 and November 25–26 — Governing Council convenes without a rate decision — before the final monetary policy meeting on December 16–17.
One decision, five brackets
The exact Polymarket event splits the outcome into −50+ bp, −25 bp, no change, +25 bp, and +50+ bp — five independent yes/no order books under negRisk architecture, not one ranked list.
Official ECB October 2026 timeline
The official rate table records the deposit facility rate at 2.00% effective this date — the end of the 2025 easing cycle and the starting point for everything that followed.
The table's next row is +25 basis points: deposit 2.25%, main refinancing 2.40%, marginal lending 2.65% — the first increase of 2026.
No new row followed the July meeting; the official table stood unchanged from June 17 into September. The September hub documented that pause as the original research baseline.
The Governing Council raised all three key rates by 25 basis points at its Berlin meeting. The settled Polymarket September event resolved the 25-basis-point-increase bucket to Yes, and the Fed hiked September 16 and the Bank of Japan September 18 in the same week.
The official table's current row: deposit facility 2.50%, main refinancing operations 2.65%, marginal lending facility 2.90% — verified live on this hub's publication day, September 29.
The official calendar still names October 28–29 (Frankfurt, monetary policy), December 16–17 next, and the verified October event is open with $240,081 cumulative volume, the no-change bracket at 77.5¢ the largest book.
The euro-area September flash inflation estimate lands in the first days of October, with final September statistics and other euro-area data following before the meeting. They can move expectations and order books, but none of them substitutes for the official October statement as resolution evidence.
The monetary policy meeting convenes Wednesday and concludes with the decision and press conference traditionally on Thursday, October 29. The reviewed market may resolve as soon as the statement or release with relevant data is issued; the postponement and cancellation fallbacks below apply only if the meeting itself moves.
The ECB's calendar lists this Governing Council meeting without a monetary policy decision — a boundary marker, not a decision date.
The next scheduled monetary policy meeting after October — and the written boundary the October contracts' postponement clause uses: an October decision delayed past its start resolves to No Change.
What the verified October Polymarket event covers
The exact public event reviewed for this guide is titled ECB Interest Rates: October 2026 (event ID 743554, open since late July 2026, scheduled to end October 30, 2026). It resolves on the change in basis points in the deposit facility rate resulting from the October 2026 meeting of the European Central Bank, relative to the level prior to that meeting, with official ECB information as the named source. The five brackets:
50+ bps decrease
A decrease classified in the 50-basis-point-or-larger bracket after the written rounding rules.
25 bps decrease
A smaller qualifying decrease classified as 25 basis points. One basis point is 0.01 percentage point.
No change
No qualifying change from the specified meeting — also the fallback bracket if the meeting is cancelled or postponed past the next scheduled meeting.
25 bps increase
A qualifying increase classified as 25 basis points — the bracket trading at 22.5¢, which would take the deposit rate to 2.75%.
50+ bps increase
An increase classified in the 50-basis-point-or-larger bracket after rounding.
Five binaries, one decision
Each outcome is a separate yes/no order book, so displayed YES prices need not sum to exactly 100¢.

$240,081
Cumulative event volume at the snapshot — the settled September event passed $600,000 before it resolved, and October has a full month of trading left.
$41,143
Event liquidity, spread across all five books — enough depth that quoted prices are meaningful rather than a single stale order.
$9,115
24-hour volume at the snapshot; rate-decision events typically compound volume fastest in the final week and on decision day itself.
ECB October market resolution: seven rules that matter
1. The deposit facility rate is the unit
The event measures the change in the deposit facility rate produced by the October 2026 meeting — not the main refinancing rate, not the marginal lending rate, not any national rate.
2. Compare before and after the meeting
Resolution uses the change relative to the level before this meeting. Today's 2.50% is the current baseline, not a fixed settlement input.
3. Official source resolves
Official ECB information — including the statement or release from the October 2026 meeting listed on the official ECB calendar — is the named resolution source, and the market may resolve as soon as that release is issued.
4. The upper bound counts if a band applies
If the specified rate is expressed as an upper and lower bound, the relevant change is the change to the upper bound. The ECB's rates are single levels, so this clause is dormant but written.
5. Odd-sized moves round
Changes under 25 bp count as 25 bp; changes over 25 bp round to the nearest 25, ties away from zero. A 10 bp hike is a +25 outcome; a 37.5 bp hike is +50.
6. Postponement and cancellation fallbacks are dated
A postponement before the December 16–17 meeting resolves on the postponed meeting's outcome; a cancellation, or a postponement past the December meeting's start, resolves to No Change.
7. Emergency actions sit outside
Emergency changes to the rate not resulting from the specified meeting are not considered — an inter-meeting move does not settle this market by itself.
These seven rules are why a meeting-specific guide beats a generic odds table: two ECB markets can settle differently on the same meeting if their meeting windows, fallbacks, or rounding clauses differ. The September hub shows the same architecture settling cleanly on a 25-basis-point increase.
Why the board leans hold — with a real second-hike tail
Two hikes are already delivered
The official table shows +25 bp in June and +25 bp in September, taking the deposit rate from 2.00% to 2.50% within sixteen months. A market pricing an October pause is pricing the pacing of a council that has moved twice — not doubt about direction.
The 2026 pattern has been move-then-pause
June's hike was followed by a July hold before September's move. Six weeks separate the September decision's effective date from the October meeting — a shorter gap than either 2026 move required, which is one reason the 22.5¢ book is a tail rather than the favorite.
The market keeps a real second-hike tail
22.5¢ for +25 bp to 2.75% is not a rounding error — it is $73,368 of contract volume in that book alone. The crowd does not treat October as settled.
The long-shot books are real too
The +50 bp bracket carries $36,560 of volume at 0.1¢, and the decrease brackets hold $36,292 between them. Round-trip speculation exists on both tails, which is why the full board — not one headline number — belongs on the record.
The data window is live
Euro-area September inflation statistics land in early and mid-October, the last major readings before the meeting. A surprise moves the 22.5¢ book first, and the refresh schedule below is built around those releases.
A four-decision central-bank week
The Fed decides October 27–28, the Bank of Canada October 28, and the Bank of Japan October 29–30 — the same week as the ECB's meeting. Cross-institution repricing is a live risk for every board in that cluster, in both directions.
Why search demand should rise before October 29
The “next meeting” wave
The settled September hub keeps collecting “ECB decision” searches; its answer and timeline now route that intent here as the October meeting approaches.
The October data wave
Euro-area September inflation releases reliably spike “ECB rate” queries, and the final September statistics land mid-October — days before this page's scheduled snapshot refresh.
A four-decision central-bank week
The Fed (October 27–28), the Bank of Canada (October 28), the ECB (October 28–29), and the Bank of Japan (October 29–30) all decide in one week. Cross-institution searches lift all four hubs together.
Decision week itself
“ECB October 2026 meeting” and “ECB decision October 2026” searches concentrate in the days around October 29, when this page will already be indexed and refreshed with the final pre-meeting board.
Research workflow for the October ECB decision
Start with the official calendar
The ECB's Governing Council calendar lists every 2026 meeting with its type: October 28–29 monetary policy, November 25–26 non-monetary, December 16–17 monetary. Verify it before trusting any secondary date.
Confirm the baseline
Check the official key-interest-rate table, not a screenshot or an article: the deposit facility level before the meeting is what the contracts measure against.
Read all five questions
Each bracket is its own market with its own book. A summary headline like “75% chance of a hold” hides four other prices and their spreads.
Measure the books
Record bid, ask, depth, volume, and a UTC timestamp together. A lone last-trade price is the weakest possible evidence.
Compare institutions carefully
The Fed decides October 27–28, the Bank of Canada October 28, the ECB October 28–29, the Bank of Japan October 29–30 — same week, different instruments, calendars, and rules. Fed odds and the October hubs for the BoC and BoJ cover their own events.
Separate context from settlement
Inflation prints, wage data, and peer-bank decisions are context. Settlement runs on the announced change in the deposit facility rate and the written fallbacks — nothing else.
Investigate sudden moves
A bracket that jumps on no news is worth checking against data releases and order-book depth before treating it as information.
Keep probability claims bounded
Prices are crowd sentiment at a timestamp. This page never presents them as the official outcome, and neither should you.
Frequently asked questions
When is the ECB October 2026 meeting?
Wednesday–Thursday, October 28–29, 2026, at the ECB in Frankfurt. The monetary policy decision and press conference traditionally follow on the second day, Thursday, October 29. The ECB's published calendar also lists September 30 and November 25–26, 2026 as non-monetary-policy Governing Council meetings, with the next monetary policy meeting on December 16–17, 2026.
What are ECB interest rates right now?
The deposit facility rate is 2.50%, the main refinancing operations rate is 2.65%, and the marginal lending facility rate is 2.90% — all effective September 16, 2026, per the ECB's official key-interest-rate table (verified September 29, 2026). The September 9–10 Berlin meeting raised all three rates by 25 basis points; the previous change was the June 17 hike that took the deposit rate to 2.25%.
What do prediction markets price for the October ECB meeting?
As of the 2026-09-29 14:12:58 UTC snapshot, Polymarket's five-outcome event prices no change at 77.5¢ (bid 76¢ / ask 79¢) against 22.5¢ for a 25-basis-point increase that would take the deposit rate to 2.75%, with roughly $240,081 in cumulative volume. Displayed prices are crowd sentiment at a timestamp — they are not the official outcome and can move immediately.
What did the ECB decide in September 2026?
The Governing Council raised all three key interest rates by 25 basis points at its September 9–10 Berlin meeting — the official table records the deposit facility rate at 2.50% effective September 16, 2026. It was the second hike of 2026 after June 17, and the settled Polymarket September event resolved its 25-basis-point-increase bucket to Yes. The September hub holds the full settled record.
Which interest rate change resolves the October market?
The event resolves on the change in basis points in the deposit facility rate resulting from the October 2026 Governing Council meeting, relative to the level in force before that meeting. The named resolution source is official ECB information, including the statement or release from the October 2026 meeting, and the market may resolve as soon as that statement is issued.
How are odd-sized ECB changes classified?
Under the event's written rules, changes smaller than 25 basis points count as 25-basis-point moves, and changes larger than 25 basis points round to the nearest 25, with an exact tie rounded away from zero — so a 10 bp hike would count as 25 bps and a 37.5 bp hike as 50 bps.
What happens if the October meeting is postponed or cancelled?
If the meeting is postponed to a date before the start of the next scheduled meeting (December 16–17, 2026), the market resolves on the outcome of that postponed meeting. If it is cancelled, or postponed so far that no decision is announced by the start of the December meeting, the market resolves to the “No Change” bracket. Emergency changes to the rate not resulting from the specified meeting are not considered.
When will this ECB October 2026 guide be refreshed?
A snapshot refresh is planned for about October 14, 2026, after the final September euro-area inflation statistics, with a final pre-meeting refresh on October 27–28 and a decision-day update on October 29. An earlier review would follow an official calendar change, a market rule change, or a major reprice.
