final rationale
Mean of 5 draws (0.89, 0.89, 0.92, 0.92, 0.91). (0) Not resolved yet. The ECB site and FRED show the deposit rate at 2.50% since the 10 Sept hike, and the 28-29 Oct meeting has not happened. (a) About 25 days remain until the 29 Oct decision; the market closes 30 Oct. (b) If nothing changes, the ECB holds: October is a non-projection meeting, and both of this cycle's hikes (June, September) came at projection meetings. (c) A NO path: energy prices keep surging after the 3.8% September flash HICP (energy at 18.8%) and services or wage signs firm up. That could prompt a back-to-back hike in October, a scenario Capital Economics says 'would not be a big surprise' if energy rises further. (d) A YES path: the ECB follows the broad sell-side consensus (Bloomberg survey, Bloomberg Economics, Standard Chartered, Capital Economics, Goldman) of holding in October and hiking in December alongside new projections. That fits Lagarde's 'no rush' and 'not embedded' messaging, Schnabel's cautious framing, and Rehn's point that higher yields are already tightening. The Polymarket anchor is 92% (bid 91, ask 93) and has risen 15.5 points in a week. €STR futures via ECB Watch showed 87% hold on 2 Oct, so the market sits slightly richer than futures. I shade a bit below the market to about 89% for the residual energy-shock tail and nearly four weeks of data still to come.

This is a Polymarket ECB-decision question, so polymarket_direct is the price anchor and resolution_source checks the ECB calendar and statement page. FRED euro-area series (deposit facility rate, HICP) give the policy and inflation backdrop. Kalshi and Polymarket related markets give cross-venue odds for the October ECB decision.

Research loops, bottom lines
- current state: The ECB hiked 25bp in September to a 2.50% deposit rate, and a surprise jump in September flash inflation to 3.8% (vs. 3.0% ECB 2026 projection) has kept a live debate about an October hike alive, but the balance of post-flash-CPI commentary (Reuters/Capital Economics, Bloomberg Economics, Goldman Sachs) and market pricing (71-87% probability of no change) currently leans toward the ECB holding in October and saving any further tightening for the December projections meeting.
- base rate: Over the last eight ECB meetings, "No Change" has been the modal outcome (roughly two-thirds of meetings), but 2026 has broken from the long 2024-25 cutting/pausing pattern with two live hikes (June, September), making this a genuinely contested, data-dependent cycle rather than a stable hold-regime; most recent trackers/polls lean toward "No Change" for October (roughly 70-87% depending on source) but not with the overwhelming consensus seen in earlier 2026 holds, and non-projection meetings li
- yes case: The strongest case for "No Change" in October rests on a now-broadening sell-side consensus (Bloomberg Economics, Standard Chartered, Capital Economics) that the September inflation spike is largely a transitory energy/base-effect phenomenon, that rising bond yields and French fiscal stress are already tightening financial conditions, and that the ECB's institutional preference is to pair any further hike with the December projections round rather than act on an interim, non-projection October m
- no case: The strongest case for a hold rests on a structural mechanism — October is a non-projection meeting with no new staff forecasts, making it a naturally lower-probability moment for action — reinforced by a direct Bloomberg economist survey calling for the ECB to skip October and hike only in December, cautious framing from Schnabel about not overreacting to single data points, and a clean historical precedent of the equivalent October 2025 non-projection meeting resolving as a hold.

report: current state
- [2026-09-10] The ECB Governing Council
decided to raise the three key ECB interest rates by 25 basis points, with the deposit facility, main refinancing operations and marginal lending facility rates increased to 2.50%, 2.65% and 2.90% respectively, with effect from 16 September 2026
. This was the second hike of the cycle. Source: https://www.ecb.europa.eu/press/pr/date/2026/html/ecb.mp260910~314e508016.en.html
- [2026-09-10] At that meeting
the baseline of the new ECB staff projections saw headline inflation averaging 3.0% in 2026, 2.5% in 2027 and 2.1% in 2028, unchanged for 2026 versus June but revised up for 2027 and 2028
, and
the outlook remained highly uncertain, with risks to the upside for inflation and to the downside for economic growth
. Source: ECB press release.
- [2026-10-02] Eurostat's flash estimate showed
euro area annual inflation expected to be 3.8% in September 2026, up from 3.2% in August
, with
the reading topping economists' forecasts of a 3.6% rise and marking the highest rate in three years
. Source: https://ec.europa.eu/eurostat/web/products-euro-indicators/w/2-02102026-ap
- [2026-10-02] The spike was driven by energy:
energy was expected to have the highest annual rate in September (18.8%, compared with 14.3% in August)
, with core/services inflation also firming modestly (services 3.2% vs 3.0%, core 2.5% vs 2.4%). Source: Eurostat.
- [2026-09-30/10-01, "6 days ago"] Reuters reported Lagarde telling the European Parliament that
"We see higher inflation ahead but no signs yet that it is becoming embedded," and "We do not see evidence at this stage of energy prices feeding into higher wages,"
while noting
many economists see the ECB sitting out its October 29 meeting and hiking only in December, when new projections are released
. Source: investing.com/Reuters.
- [2026-09-10] Immediately after the September hike, market pricing (LSEG-based reporting) showed
roughly a 71% probability that rates stay unchanged at the October meeting, with a 28-29% chance of another 25 basis point hike to 2.75%
. Source: kucoin.com.
- [2026-09-10] Reuters sources (reported same day) said
ECB policymakers expect additional policy tightening in the coming months... and another move could arrive as early as October
, though
any decision would depend entirely on incoming data and developments in Iran
. Source: indexbox.io citing Reuters.
- [2026-10-03, "1 day ago"] Following the 3.8% flash print, commentary indicates odds of an October hike are receding:
the ECB is seen lifting rates at least two more times, though market odds of an October move are fading... Traders are trimming bets on an October hike
, and
Lagarde signaled there's no rush to tighten again
, with
economist David Powell expecting the Governing Council to hold off on any urgent October action and to "probably only hike one last time in December."
Source: briefs.co.
- [2026-10-02, "2 days ago"] A separate Capital Economics view cited in Yahoo Finance/Reuters coverage:
"September's (inflation) data don't alter our view that the ECB is most likely to wait until December to raise interest rates again," Jack Allen-Reynolds said, adding "if energy prices rose further in the next few weeks, an October hike would not be a big surprise."
- [~2026-09-25, "9 days ago"] Goldman Sachs Research
forecasts one more hike in December 2026
while noting
market pricing suggests better-than-even odds that the ECB will hike rates in back-to-back rate-setting meetings
, which Goldman views as a higher hurdle than currently priced. Source: goldmansachs.com.
- [2026-10-02] Current Deposit Facility Rate stands at 2.50% (effective since 16 Sept 2026), confirmed by ECB and Eurostat-linked reporting; no ECB meeting or decision has occurred between September 10 and today (October 4). Next scheduled Governing Council meeting is October 28-29, 2026, per the ECB calendar, with decision expected ~14:15 CET on Oct 29.
- [2026-10-02] Third-party rate-probability tracker (ECB Watch, using €STR futures) showed
market pricing implying an 87.0% probability of interest rates maintaining at 2.50% at the October 29, 2026 meeting, versus 13.0% for a 25bp hike to 2.75%
(data as of Oct 2, 2026) — this is a third-party estimate, not the Polymarket contract itself.
BOTTOM LINE: The ECB hiked 25bp in September to a 2.50% deposit rate, and a surprise jump in September flash inflation to 3.8% (vs. 3.0% ECB 2026 projection) has kept a live debate about an October hike alive, but the balance of post-flash-CPI commentary (Reuters/Capital Economics, Bloomberg Economics, Goldman Sachs) and market pricing (71-87% probability of no change) currently leans toward the ECB holding in October and saving any further tightening for the December projections meeting.
NOT FOUND: No post-flash-CPI (Oct 2) official ECB communication, Governing Council member speech, or a post-October-2 Reuters poll explicitly addressing the October 29 decision; the October 8, 2026 ECB account of the September meeting (minutes) had not yet been published/reviewed as of this report.
report: base rate
- [2026-02-05] The ECB
kept policy rates unchanged for the fifth consecutive meeting, with its key interest rate at 2%
, and
around 85% of economists surveyed by Reuters in their January poll said the ECB would leave rates unchanged over the rest of 2026
. https://www.cnbc.com/2026/02/05/ecb-rate-decision-economists-analysts-next-move.html
- [2026-03-19] and [2026-04-30] Further holds: in April the ECB's
governing council opted to hold its benchmark deposit facility rate at 2%
, continuing a long run of "no change" outcomes. https://www.cnbc.com/2026/04/30/european-central-bank-april-2026-rate-decision-inflation-stagflation-risk-iran-war.html
- [2026-06-11] The streak of holds ended: the ECB raised its deposit rate from 2.00% to 2.25%,
beginning a cycle of rate hikes with policymakers resuming raising rates in June 2026
after eight prior cuts. https://www.morningstar.com/economy/will-ecb-raise-interest-rates-again-2026-cut-them-2027
- [2026-07-23] At the next meeting the ECB reversed to a hold:
the Governing Council decided to keep the three key ECB interest rates unchanged, remaining at 2.25%, 2.40% and 2.65% respectively
. https://www.ecb.europa.eu/press/pr/date/2026/html/ecb.mp260723~29f24d99bc.en.html
- [2026-09-10] Then another hike:
the Governing Council decided to raise the three key ECB interest rates by 25 basis points, to 2.50%, 2.65% and 2.90% respectively
, the second hike of 2026. https://www.ecb.europa.eu/press/pr/date/2026/html/ecb.mp260910~314e508016.en.html
- Reference class (last 8 meetings, Feb–Sep 2026): Hold, Hold, Hold, Hike(+25), Hold, Hike(+25) — i.e., 4 of 6 meetings since Feb were "no change," with the two deviations each being +25bp hikes; no cuts occurred in this window, making "No Change" historically the modal outcome but not a lock given the current hiking cycle.
- [2026-10-02] Market pricing as reported by one tracker shows a split view:
for the upcoming meeting on October 29, 2026, markets price an 87.0% probability of no change, with 13.0% implying a move to 2.75%
(ECB Watch, using €STR futures). https://ecb-watch.eu/
- [2026-10-02] A competing contemporaneous estimate cited elsewhere put the odds differently:
as of late September, markets were pricing roughly 60 percent hike probability of a 25-basis-point increase at the October 29 meeting
, with the October meeting not accompanied by new staff projections, making it "data dependent" on September inflation. https://www.techtimes.com/articles/328481/20261002/ai-debt-glut-doing-ecbs-tightening-work-rehn-says-before-october-vote.htm
- [2026-09-28 (approx, per oraclemarkets snapshot)] An aggregator citing AI-model consensus and prediction markets put
the most likely outcome as no change at the Oct 29, 2026 meeting (72% per AI agents)
, alongside other prediction-market readings in a similar range. https://oraclemarkets.io/dashboards/ecb-rates
- [2026-10-02] A Bank of Finland governor argued that
rising long-term interest rates driven by an AI bond issuance surge are already performing part of the tightening work the ECB would otherwise need to do by hiking
, implying the bar for an October hike may be higher than futures pricing implied, with the decision characterized as "a genuine 50/50 in substance." https://www.techtimes.com/articles/328481/20261002/ai-debt-glut-doing-ecbs-tightening-work-rehn-says-before-october-vote.htm
- [2025-12-18 to 2026-04-30] Historical pattern this cycle: prior to June's hike, the ECB held for at least four consecutive meetings (Dec 2025, Feb, Mar, Apr 2026) at 2.00% deposit rate, only moving once new projection rounds or exogenous shocks (Middle East energy shock) forced a reassessment — suggesting non-projection meetings (like October, which has no new staff forecasts) have historically had a lower base rate of producing changes than projection meetings (March, June, September, December). https://tradingeconomics.com/euro-area/interest-rate/news/511076
BOTTOM LINE: Over the last eight ECB meetings, "No Change" has been the modal outcome (roughly two-thirds of meetings), but 2026 has broken from the long 2024-25 cutting/pausing pattern with two live hikes (June, September), making this a genuinely contested, data-dependent cycle rather than a stable hold-regime; most recent trackers/polls lean toward "No Change" for October (roughly 70-87% depending on source) but not with the overwhelming consensus seen in earlier 2026 holds, and non-projection meetings like October have historically been less likely to see changes than projection meetings.
NOT FOUND: No official Reuters/Bloomberg economist poll specifically for the October 2026 meeting was found (unlike earlier 2026 meetings, which had published polls); could not verify a single authoritative consensus number, only competing aggregator/tracker estimates with real divergence between sources.
report: yes case
YES means: the ECB keeps all three key rates unchanged at its October 28-29, 2026 meeting (deposit facility rate stays at 2.50%), resulting in the "No Change" resolution per the contract's rounding rules.
- [2026-10-03] A Bloomberg Economics note cited the day before the ECB publishes its September account states
"The hurdle for an October rate hike is now high... subsequent data have strengthened the case for patience. Sticky services inflation could keep open the option of a December hike - but the Fed will probably need clearer evidence that price pressures have re-emerged before tightening again,"
with the parallel euro-area read that
September euro-area inflation quickened beyond forecasts, largely due to war-related energy costs, yet investors see very slim chances of an October ECB hike
. https://www.briefs.co/news/fed-and-ecb-dial-back-near-term-hike-urgency-after-soft-us-j/
- [2026-10-03] The same report notes French fiscal/bond-market stress is compounding caution, observing
that softer US hiring and wages, plus strain in French bond markets, have cooled talk of quick follow-up hikes at the Fed and ECB
, a fresh macro-risk channel arguing for a hold rather than tightening into market stress.
- [2026-10-02] Standard Chartered's Global Research team argues
core inflation has drifted only modestly higher since late February, rising from 2.2% in January to 2.5% y/y in September, and these factors limit the likelihood of an October hike, with the Governing Council preferring to wait for new macroeconomic projections... the next of which will accompany the December policy meeting
. https://www.fxstreet.com/news/euro-october-ecb-hike-odds-seen-limited-standard-chartered-202610021302
- [2026-10-02] Standard Chartered further flags a growth/financial-conditions channel:
higher yields pose downside risks to both growth and inflation... Lagarde has highlighted the downside risks to both growth and inflation arising from higher yields
— an argument that tightening financial conditions via bond yields is already doing some of the ECB's work, reducing the case for an additional hike.
- [2026-10-03] Bloomberg Economics' detailed inflation decomposition (via briefs.co) concludes
the quarterly means for both headline and core match the ECB's latest projections, the uptick mainly reflects an airfare base effect, momentum in services inflation has eased, and soaring sovereign yields have tightened financial conditions further... senior euro-area economist David Powell expects the Governing Council to hold off on any urgent October action and to "probably only hike one last time in December."
https://www.briefs.co/news/euro-area-inflation-pops-to-3-8-in-september-nudging-ecb-tow/
- [2026-09-30/10-01] Lagarde's own framing to the European Parliament reinforces patience: as previously reported, she said inflation is not yet becoming embedded, and the Reuters piece adds
many economists see the ECB sitting out its October 29 meeting and hiking only in December, when new projections are released... Lagarde repeated her earlier message that interest rates will not move in lockstep with energy costs
. https://www.investing.com/news/economy-news/measured-ecb-hikes-to-quell-inflation-remain-appropriate-lagarde-says-4920668
- [2026-10-03] ECB Executive Board member Isabel Schnabel, a known hawk, is reported to have said
a "clearer picture" of inflation will take shape over the coming months
rather than calling for immediate action — notable because even hawks are not pushing urgently for October.
- [2026-09-26] A structural/institutional factor adds friction to any October move: with
Isabel Schnabel, head of the bank's market operations, will leave her post a year early to take a senior role at the IMF
, and succession jockeying for Lagarde, Lane and Schnabel's roles underway, the Governing Council has competing institutional distractions that historically favor continuity/hold decisions at non-projection meetings.
- [2026-10-04] Mechanism for YES: October is not a projection-round meeting (next staff forecasts come in December), and per Standard Chartered's explicit framing (2026-10-02), the ECB's institutional preference is to pair any rate change with fresh macro projections — structurally lowering the odds of an October move regardless of the September inflation spike.
- [2026-10-03] Multiple independent analyst channels converging the same week (Bloomberg Economics, Standard Chartered, ING-adjacent commentary via Capital Economics already in prior reports) all converge on the same December-hike, October-hold call, suggesting a broadening sell-side consensus rather than a single outlier view.
BOTTOM LINE: The strongest case for "No Change" in October rests on a now-broadening sell-side consensus (Bloomberg Economics, Standard Chartered, Capital Economics) that the September inflation spike is largely a transitory energy/base-effect phenomenon, that rising bond yields and French fiscal stress are already tightening financial conditions, and that the ECB's institutional preference is to pair any further hike with the December projections round rather than act on an interim, non-projection October meeting.
NOT FOUND: No official ECB Governing Council member speech or the September 9-10 account/minutes (due for publication ~Oct 8, 2026) explicitly ruling out an October move; no post-flash-CPI Reuters poll of economists specifically covering the October 29 decision.
report: no case
YES means: the ECB's October 29, 2026 Governing Council decision leaves the deposit facility rate unchanged at 2.50% (i.e., "No Change" resolution), rather than a hike (or cut) relative to the pre-meeting level.
- [2026-09-18] A Bloomberg survey of economists found that respondents
expect the Governing Council to lift the deposit rate to 2.75% at its last meeting of the year, skipping the next opportunity to do so in late October
, directly pointing to a hold in October with the next hike deferred to December.
- [2026-09-30] In her Luxembourg speech, Executive Board member Isabel Schnabel framed current pressures as a sequence of shocks rather than demanding instant action:
monetary policy is often analysed in terms of how it should respond to a single shock... central banks are facing a sequence of overlapping shocks, with the effects of earlier disturbances still working their way through the economy
— language consistent with a cautious, data-accumulating stance rather than signaling imminent tightening at the very next meeting.
- [2026-09-30] Schnabel's framework emphasizes that policy should respond to the comprehensive staff-projection assessment, not to any single data print:
Monetary policy then responds to that comprehensive assessment: if the resulting inflation outlook is above target, policy needs to adjust to bring inflation back to 2% over the medium term
— mechanically favoring December (a projections meeting) over October (not) as the decision point.
- [undated, pre-Oct] A dedicated ECB-meeting calendar explainer underscores the structural reason October is a lower-probability move:
October is not one of the ECB's four quarterly projection meetings... no new staff inflation or GDP forecasts will be released on October 29. The Governing Council's decision and President Lagarde's press conference will be the sole communications
, and
October's primary significance is as a bridge between the September data-rich decision and the December year-end review
.
- [updated 2026-08-25] The same tracker's base-case scenario explicitly favors a hold:
The most likely October outcome is a hold at whatever level the deposit rate stands following September, with forward guidance focused on the December decision
, while characterizing a hike as contingent on a fresh shock and a cut as "unusual" for a non-projection meeting.
- [2026-09-17] Even hawkish-leaning Governing Council voices stopped short of committing to an October move: Governor Gabriel Makhlouf said only that
there's currently no worrying sign of inflation spreading into wages, officials will take each decision on borrowing costs as it comes
— "live" rhetoric, not a pre-commitment to act in October.
- [2026-10-02] Mechanistically, the Bank of Finland's Olli Rehn-linked framing noted elsewhere in colleagues' research suggests rising market-driven yields are doing some of the tightening work for the ECB, reducing the need for an immediate policy-rate move — a structural brake on an October hike even after the hot CPI print.
- [Historical precedent] The immediately preceding October meeting, in 2025, resolved as a hold: Reuters reported
the central bank has repeatedly said it will take a meeting-by-meeting and data dependent approach to rate setting, and it repeated this stance
after holding, and a contemporaneous ECB Watcher estimate put the bias at
90% Cut, 5% Unclear... We estimate that 90% of the voting members of the ECB Governing Council will support maintaining the current key interest rate level at the meeting on October 30
(Oct 2025) — illustrating that in this cycle's non-projection October slot, inertia/hold outcomes have been the norm even amid live two-sided debate.
- [Resolution-criteria technicality] Per the rules, if the October 28-29 meeting is cancelled or postponed past the December 17 meeting with no decision announced, the market automatically resolves "No Change" — an additional, non-data-dependent path to a NO-case (Yes-on-hold) outcome that requires no economic argument at all, only a scheduling disruption.
- [Reference-class base rate] Across the ECB's last eight meetings (per colleagues' tally, Feb–Sep 2026), four of six meetings were holds, and both deviations were confirmed, projection-round hikes (June, September) — reinforcing that non-projection meetings like October have so far not been the venue for rate changes in this cycle.
BOTTOM LINE: The strongest case for a hold rests on a structural mechanism — October is a non-projection meeting with no new staff forecasts, making it a naturally lower-probability moment for action — reinforced by a direct Bloomberg economist survey calling for the ECB to skip October and hike only in December, cautious framing from Schnabel about not overreacting to single data points, and a clean historical precedent of the equivalent October 2025 non-projection meeting resolving as a hold.
NOT FOUND: No post-flash-CPI (after Oct 2) Reuters or Bloomberg poll specifically re-surveying economists on the October 29, 2026 decision; no ECB official's explicit, dated statement after the September 30 CPI shock ruling out an October hike.

(0) Not resolved yet. The ECB site and FRED show the deposit rate at 2.50% since the 10 Sept hike, and the 28-29 Oct meeting has not happened. (a) About 25 days remain until the 29 Oct decision; the market closes 30 Oct. (b) If nothing changes, the ECB holds: October is a non-projection meeting, and both of this cycle's hikes (June, September) came at projection meetings. (c) A NO path: energy prices keep surging after the 3.8% September flash HICP (energy at 18.8%) and services or wage signs firm up. That could prompt a back-to-back hike in October, a scenario Capital Economics says 'would not be a big surprise' if energy rises further. (d) A YES path: the ECB follows the broad sell-side consensus (Bloomberg survey, Bloomberg Economics, Standard Chartered, Capital Economics, Goldman) of holding in October and hiking in December alongside new projections. That fits Lagarde's 'no rush' and 'not embedded' messaging, Schnabel's cautious framing, and Rehn's point that higher yields are already tightening. The Polymarket anchor is 92% (bid 91, ask 93) and has risen 15.5 points in a week. €STR futures via ECB Watch showed 87% hold on 2 Oct, so the market sits slightly richer than futures. I shade a bit below the market to about 89% for the residual energy-shock tail and nearly four weeks of data still to come.

(0) Not resolved yet. FRED and the ECB show the deposit rate at 2.50% since the 16 September hike, and the October 28-29 meeting has not happened. The ECB pages fetched show nothing newer than the 10 September press conference. (a) About 25 days remain until the October 29 decision, the only event that matters. (b) Status quo is a hold. October is a non-projection meeting, and in this cycle both hikes (June, September) came at projection meetings while the non-projection meetings held. (c) NO scenario: energy prices spike further on Iran developments after the 3.8% September flash HICP, and hawks push a back-to-back 25bp hike to 2.75%. Capital Economics says an October hike 'would not be a big surprise' if energy rose further. (d) YES scenario: the ECB holds and signals December, when new projections arrive. Several sources support this: Bloomberg's survey and Bloomberg Economics (Powell), Standard Chartered, Capital Economics, Goldman Sachs, Lagarde's 'no rush' framing, and Schnabel's patience. Rising yields and French bond stress are also tightening financial conditions on their own. The Polymarket anchor is 92% (bid 91, ask 93), up 15.5 points this week. The €STR futures tracker showed 87% hold as of Oct 2, and one outlier source cited 60% hike odds in late September. I shade slightly below the market toward the futures-implied level, given the live energy and geopolitical tail and the hot core and services firming.

The event is not resolved: the ECB source fetch contains no October decision, while the September 10 ECB release and FRED observations through October 2 establish a current deposit facility rate of 2.50%. There are 25 days until the scheduled October 29 announcement, ahead of the October 30 trading close, although the rules accommodate a qualifying postponement before the next scheduled meeting. I retain Polymarket's 92% Yes anchor, with a 91–93% spread, because the research supplies no clear unpriced advantage over a market that has already risen 15.5 percentage points in a week. The status quo and main YES scenario are an unchanged deposit rate, probably 2.50%, while policymakers await December projections; Reuters' September 30/October 1 Lagarde remarks about limited wage pass-through and Standard Chartered's October 2 analysis support this, as does the June-hike/July-hold/September-hike cadence. A NO scenario is another energy surge or evidence of broader inflation persistence prompting an October hike, with Eurostat's October 2 report of 3.8% headline inflation and firmer services inflation providing a credible starting point. The October 2 futures-derived 87% hold estimate and missing post-inflation official guidance support retaining meaningful surprise risk, but weaker aggregators and the mislabeled NO report, which mostly repeats arguments for holding, do not justify a substantial adjustment. The incomplete official-source extraction is an evidence gap included in the residual uncertainty, not proof of a hold, and resolution requires the October meeting's deposit-rate decision rather than changes to other rates or unrelated emergency actions. Cancellation or postponement without a decision by the start of the next scheduled meeting would instead resolve Yes under the explicit default rule.

As of October 4, the event is unresolved: the ECB resolution-source scrape contains September references and navigation, not an October decision. The scheduled October 29 announcement is 25 days away, before the October 30 trading close; a postponed decision counts before the next scheduled meeting, while cancellation or postponement without a decision by that meeting defaults to Yes. I retain Polymarket's 92% Yes anchor (91% bid, 93% ask), because the research provides no clearly unpriced information warranting a deviation. The status quo is a 2.50% deposit rate, supported by the ECB's September 10 release and FRED through October 2; leaving that rate unchanged at the specified meeting produces Yes, irrespective of changes to other rates. A plausible Yes scenario is that limited energy-to-wage transmission, tighter bond-market conditions, and modest underlying inflation persuade policymakers to await December projections, consistent with Lagarde's late-September Reuters remarks and Standard Chartered's October 2 analysis. A plausible No scenario is renewed energy escalation or stronger second-round inflation evidence prompting another hike, with Eurostat's October 2 release showing headline inflation accelerating to 3.8% and services inflation also firming. The four-of-six recent hold frequency is only a small reference class, while conflicting third-party pricing and the mislabeled NO report—which actually argues for a hold—limit independent corroboration. The incomplete official-source scrape is a verification gap rather than evidence of resolution, so I retain an 8% allowance for a meeting-specific change and residual evidence uncertainty instead of treating today's unchanged rate as sufficient.

(0) The event is unresolved: the ECB resolution source shows only the September 10 decision raising the deposit facility rate to 2.50%, and an official October 29 statement is still required. (a) There are about 25 days until the October 28-29 meeting, leaving time for additional inflation data, ECB communications, or market stress to alter the decision. Polymarket’s 92% YES price is the primary anchor, while the independent €STR-based tracker’s 87% hold estimate supports only a modest discount rather than a large departure. (b) If nothing changes, the deposit rate remains 2.50% and the market resolves Yes; cancellation or postponement beyond the next meeting would also resolve as no change. (c) A No scenario is that persistent 3.8% headline inflation, firming core and services inflation, or another energy shock prompts a 25-basis-point October hike. (d) The stronger Yes scenario is that officials treat the inflation spike as energy-driven and not embedded in wages, wait for December’s staff projections, and recognize that higher bond yields are already tightening financial conditions. The broad Bloomberg Economics, Standard Chartered, Capital Economics, and economist-survey preference for an October hold outweighs the hot inflation print, though the absence of a post-CPI official commitment keeps the forecast just below the market price.

Yes: 91%
No: 9%
Mean of 5 draws (0.89, 0.89, 0.92, 0.92, 0.91). (0) Not resolved yet. The ECB site and FRED show the deposit rate at 2.50% since the 10 Sept hike, and the 28-29 Oct meeting has not happened. (a) About 25 days remain until the 29 Oct decision; the market closes 30 Oct. (b) If nothing changes, the ECB holds: October is a non-projection meeting, and both of this cycle's hikes (June, September) came at projection meetings. (c) A NO path: energy prices keep surging after the 3.8% September flash HICP (energy at 18.8%) and services or wage signs firm up. That could prompt a back-to-back hike in October, a scenario Capital Economics says 'would not be a big surprise' if energy rises further. (d) A YES path: the ECB follows the broad sell-side consensus (Bloomberg survey, Bloomberg Economics, Standard Chartered, Capital Economics, Goldman) of holding in October and hiking in December alongside new projections. That fits Lagarde's 'no rush' and 'not embedded' messaging, Schnabel's cautious framing, and Rehn's point that higher yields are already tightening. The Polymarket anchor is 92% (bid 91, ask 93) and has risen 15.5 points in a week. €STR futures via ECB Watch showed 87% hold on 2 Oct, so the market sits slightly richer than futures. I shade a bit below the market to about 89% for the residual energy-shock tail and nearly four weeks of data still to come.
