Eurozone headline inflation accelerated to a three-year high of 3.8% in September 2026, driven primarily by energy prices surging to 18.8% year-over-year amid the Middle East conflict, which has lifted oil, gas, and refined product costs. This follows the ECB’s September 25-basis-point rate hike to a 2.5% deposit facility rate and aligns with staff projections for 3.0% average HICP inflation in 2026, though risks remain skewed higher from persistent energy pass-through and resilient services prices at 3.2%. Trader consensus pricing 3.1%+ at 90.5% reflects these near-term pressures and limited evidence of rapid de-escalation. Key swing factors include October 29 ECB policy signals, further energy price volatility, and any material cooling in core measures around 2.5%.
