Headline inflation rose to 3.8% from 3.2% in August. Euro-area inflation accelerated far more than policymakers wanted in September, driven by energy and food prices and accompanied by a smaller rise in core inflation. The jump reinforced expectations that the European Central Bank’s 2026 hiking cycle might not be finished.
What happened
Core inflation increased to 2.5%, with services remaining an important source of pressure. The ECB had already raised rates twice during the summer, and markets were debating whether another move would come quickly or be delayed until December.
Why it matters now
It helps to separate headline and core inflation is crucial. Energy prices can move sharply and reverse, but services inflation tends to be more persistent because it is closely linked to wages and domestic demand. A rise in both measures gives policymakers less confidence that the shock will disappear on its own.

The policy question
Governments also face a difficult fiscal choice. Subsidizing household energy bills can soften the cost-of-living shock but increases deficits and may sustain demand. At the same time, higher ECB rates raise debt-service costs, especially in countries already under fiscal pressure.
Looking ahead
The ECB is likely to focus on whether wages and inflation expectations remain anchored. If core inflation stays relatively stable, officials can move gradually. A further broadening of price pressure would strengthen the case for another hike before year-end.
