European inflation accelerates on energy costs, seven months into Iran conflict
Spain's harmonized inflation reached 5% in September 2026, the highest since February 2023, with France and Poland also showing faster price growth driven by energy. The uptick coincides with seven months of disruption from the Iran war that began 28 February.

What happened
Spain reported harmonized inflation of 5% in September 2026, marking the highest reading since February 2023. France and Poland also posted accelerating price growth. Energy costs led the increases across these economies. These readings emerged seven months after the Iran war commenced on 28 February 2026.
Why it matters
Sustained energy-price inflation in major eurozone economies signals that supply disruptions from the Iran conflict are feeding through to consumer prices and broadening beyond headline energy into core inflation dynamics. This complicates ECB policy calibration: higher energy inflation may prove sticky if geopolitical risk persists, forcing a choice between tolerating above-target inflation or tightening further into weakening growth.
Market transmission
First-order: Iran conflict → crude/refined product supply constraints → elevated energy input costs → retail energy prices and transport costs. Second-order: sticky energy inflation → wage-price spiral risk in tight labor markets → core inflation persistence → ECB forced to maintain or extend restrictive stance → higher real rates → demand destruction in rate-sensitive sectors (autos, construction, discretionary); potential fiscal pressure on governments if energy subsidies extend.
What to watch
ECB forward guidance and next rate decision; core inflation ex-energy in October eurozone CPI; wage growth data in Spain, France, Poland; crude oil price stability and any escalation in Iran conflict; energy futures curve for winter demand signals; eurozone PMI and consumer confidence to gauge demand resilience.
