The ECB's October 2026 decision to hold the deposit rate at 2.5% while signaling a likely December move, combined with eurozone headline inflation climbing to 3.8-4.0% on energy and food costs, has anchored trader expectations for a 25 basis point hike at the December 17 meeting. Geopolitical pressures pushing oil and gas prices higher have kept upside risks to inflation dominant, prompting Governing Council members to describe the path as clear absent major data shifts, even as core inflation stayed near 2.5% with limited second-round effects observed. Recent analyst surveys and economist polls converge on a single quarter-point adjustment to 2.75% before any pause, consistent with the market's 85% pricing for that outcome. Fresh projections, wage data, and energy price updates due in December remain the key variables that could still influence the final decision.
