Will the ECB announce no change at the December 2026 meeting?

This market resolves on the ECB's December 2026 meeting: the 'no change' outcome wins if the Governing Council leaves its key rates (deposit, main refinancing, marginal lending) untouched at that meeting. The market prices this at just 11.5%, while our model puts it at 65%. Context: after the 2024–2025 easing cycle, the deposit rate has moved close to neutral, and the ECB has repeatedly signalled pauses to assess policy transmission.

The key drivers behind our estimate are euro-area core inflation, which is steadily decelerating toward the 2% target but remains sticky in services, and weak growth. With that mix, the ECB has little reason to move rates at every meeting: historically, once at a neutral level, the central bank prefers extended pauses. The December 2026 meeting is neither a 'starting' nor a 'crisis' meeting, so the probability of holding rates is high. The market's 11.5% price implies either another cut or a hike — scenarios that require a sharp reversal in macro data.

For the outcome to win, the ECB simply has to keep rates unchanged in December 2026. That is the base case absent a recession or an inflation shock. Risks: an energy- or wage-driven inflation acceleration forcing a hike, or a sharp economic deterioration pushing a cut. Communication also matters: even a hint of a policy shift could move the price. But on current data, a pause is the most likely outcome, and 11.5% looks substantially underpriced.

The main risk to the idea is the horizon: nearly two years to December 2026, during which both recession and a new inflation spike are possible. If the ECB resumes cutting or instead hikes, the 'no change' outcome loses. The market could also be right if participants see signals the model misses. A sustained one-directional rate trend into December 2026 would invalidate the idea.
