Persistent inflation above the ECB’s 2% target, driven by energy price surges from Middle East conflict, prompted the September 10 hike of the deposit facility rate to 2.50% and upward revisions to 2027-2028 inflation forecasts. Officials have signaled openness to additional tightening if price pressures persist, supporting the 32% market-implied probability of a further 25 basis point increase at the October 28-29 meeting. The 66.5% odds on no change reflect the data-dependent stance and expectations that the Governing Council will monitor incoming HICP readings, wage trends, and growth resilience before committing to another move, consistent with historical patterns around consecutive hikes.

The resolution source will be official information from the European Central Bank, including the statement or release from its October 2026 meeting, scheduled for October 28-29, 2026, as listed on the official European Central Bank calendar (https://www.ecb.europa.eu/press/calendars/mgcgc/html/index.en.html). This market may resolve as soon as the statement or release of the European Central Bank's October 2026 meeting with relevant data is issued.
If the specified rate is defined by an upper and lower bound, the relevant change will be the change to the upper bound.
If the specified rate is changed to a level not expressed in the displayed options, the change will be rounded according to the following guidelines. Increases or decreases of less than 25 bps will be rounded to 25 bps (e.g. an increase or decrease of 10 bps would be considered to be an increase or decrease of 25 bps). Increases or decreases of greater than 25 bps will be rounded to the nearest 25 bps and will be rounded away from 0 in cases of equidistance (e.g., an increase or decrease of 37.5 bps would be considered to be an increase or decrease of 50 bps). Displayed options of “Increase” or “Decrease” will include policy rate increases or decreases of any size.
If the specified meeting is postponed to a date and time before the start of the next scheduled meeting, this market will resolve based on the outcome of that postponed meeting. If the specified meeting is cancelled, or postponed such that no decision is announced by the start of the next scheduled meeting, this market will resolve to the “No Change” bracket. Emergency changes to the specified rate not resulting from the specified meeting will not be considered.
