Elevated eurozone inflation, driven by energy price spikes from the Middle East conflict, remains the dominant factor anchoring trader expectations for a 25 basis point ECB rate hike at the September 10 meeting. The central bank's June 2026 decision to raise the deposit facility rate to 2.25% and its updated staff projections showing headline inflation averaging 3.0% for the year have reinforced a data-dependent tightening path. Recent July communications from officials indicated readiness for another increase absent clear improvement in the outlook, with futures markets and analyst surveys aligning closely with the current 86.5% implied probability. A no-change outcome retains modest scope if incoming wage or services data soften markedly before the meeting.

The resolution source will be official information from the European Central Bank, including the statement or release from its September 2026 meeting, scheduled for September 9-10, 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 September 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.
