Eurostat's flash estimate puts euro-area headline HICP inflation at 2.9% in September 2026, down from 3.2% in August. The decline is primarily mechanical: energy prices, which had surged on an annual basis in August due to base effects from the low prices of summer 2025, are now seeing that base effect fade.
Energy base effect rolling off
Energy inflation in August reached 14.3% — a reading inflated by the very low energy prices of August 2025. As those low-price months move further into the 12-month comparison window, the base effect diminishes. Eurostat's flash estimate implies energy inflation around 8% in September — still elevated, but meaningfully lower. This is a textbook base effect unwinding, not an underlying improvement in energy market conditions. The Eurostat euro indicators portal published the flash on 2 October at 11:00 CEST.
Core holding steady
The flash estimate is less detailed on components than the final (due 16 October), but the implied core reading — HICP excluding energy, food, alcohol and tobacco — appears steady at around 2.5%, down slightly from 2.6% in August. Services inflation, the most closely watched persistence measure for the ECB, likely eased modestly. We will update with component detail after the 16 October final release.
ECB implications
With headline inflation at 2.9% — approaching the ECB's 2% target — and core seemingly stable, market attention will turn to the ECB's October meeting. The ECB's post-meeting press conference and Economic Bulletin will be the key sources for policy guidance. You can track euro-area inflation history going back to the 1990s using our live explorer.
