Recent Middle East energy price shocks and the ECB's September 10 rate hike to 2.50% have shifted trader consensus toward another 25-basis-point increase by the December 16-17 meeting. Updated staff projections show headline inflation averaging 3.0% in 2026 with upside risks persisting into 2027, while euro-area growth forecasts were revised higher to reflect economic resilience. Major banks including Deutsche Bank, Morgan Stanley, and Barclays now anticipate a final tightening step in December after skipping October, citing elevated oil and gas costs alongside limited evidence of second-round effects so far. This environment supports the current implied probabilities, with data releases and the October meeting serving as key checkpoints before year-end policy calibration.

The resolution source will be official information from the European Central Bank, including the statement or release from its December 2026 meeting, scheduled for December 16-17, 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 December 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.
