Recent Eurozone HICP inflation surged to 3.8% year-over-year in September 2026, exceeding expectations and marking the highest level since September 2023, primarily due to energy prices jumping 18.8% amid Middle East geopolitical tensions. This momentum has reinforced trader consensus around an annual average above 3.1% for 2026, reflected in the 90.5% implied probability on Polymarket, consistent with ECB staff projections that were already revised higher for the year. Core measures rose modestly to 2.5%, while services and food components also accelerated. Key upcoming catalysts include the October 29 ECB Governing Council meeting and remaining 2026 data releases, though a sharp reversal in energy costs or subdued wage growth could still pressure the annual figure lower before year-end resolution.
