Annual inflation in the eurozone accelerated to 4% in October 2026 from 3.8% in September, as sharply rising energy costs pushed up consumer prices across the single-currency bloc, according to Eurostat’s flash estimate released on November 4.
The preliminary reading covers the 21 countries using the euro. It marked the highest inflation rate since September 2023 and matched economists’ expectations in a Reuters poll. Consumer prices rose 0.4% compared with September.
Energy prices drive the increase
Annual energy inflation climbed to 20.8% in October from 18.9% in September, according to reporting on Eurostat’s release. The acceleration made energy the principal driver of the higher headline figure.
The change in the headline rate amounts to an increase of 0.2 percentage points. The 4% figure measures the change in consumer prices over a year, not a 4% increase during October alone.
Core inflation remains unchanged
Core inflation, which excludes energy, food, alcohol and tobacco, held steady at 2.5%. That distinction separates October’s energy-led rise in headline inflation from the unchanged underlying measure.
Eurostat measures price growth through the Harmonised Index of Consumer Prices, which provides a comparable inflation measure across participating countries. The euro-area estimate reflects the currency bloc, rather than the entire European Union.
ECB faces renewed attention over rates
The headline reading is twice the European Central Bank’s 2% medium-term inflation target. Reuters reported that the increase was likely to reinforce market expectations of another interest-rate rise in December.
Those expectations are not an announced policy decision. The unchanged core reading and the sharp rise in energy inflation provide different signals for policymakers assessing whether price pressures are becoming more persistent.
Preliminary estimate subject to revision
The October figures are flash estimates and may be revised when Eurostat publishes its full inflation release. The initial data nevertheless show a clear contrast: headline price growth accelerated, while core inflation remained at September’s level.
