Eurozone Inflation Confirmed at 3.8%. Energy Costs Surge

Erozone inflation rose to 3.8% in September, its fastest pace this year, as a sharp climb in energy costs fed through to consumer prices, the European Union’s statistics office Eurostat reported on Friday. The final reading matched the flash estimate published on 2 October and marked a steep acceleration from 3.2% in August and 2.2% a year earlier.

Across the wider 27-nation European Union, annual inflation also reached 3.8%, up from 3.2% in August and 2.6% in September 2025. Prices in both the euro area and the EU rose 0.6% from the previous month.

Energy drives the jump

Energy was the single biggest contributor. Eurostat’s figures show energy prices were 18.9% higher than a year earlier, up from 14.3% in August, and added 1.71 percentage points to the headline rate. A year ago, energy was a slight drag on inflation, with prices falling 0.4%. In September alone, energy prices climbed 4.0% from August.

Services, the largest component of the consumer basket, contributed 1.52 points, with services inflation edging up to 3.2% from 3.0%. Non-energy industrial goods added 0.29 points, while food, alcohol and tobacco contributed 0.25 points. Unprocessed food prices rose 4.0% on the year.

Underlying price pressure also firmed, though far less dramatically. Inflation excluding energy, food, alcohol and tobacco, a measure closely watched by economists as a gauge of core trends, ticked up to 2.5% from 2.4%.

Broad-based rise across member states

The increase was widespread. Compared with August, annual inflation rose in 23 EU member states, held steady in three and fell in just one. Brussels-based outlet Eunews, summing up the data bluntly as “Inflation is not falling,” identified Slovakia as the only country where the rate eased, with Lithuania, Cyprus and Portugal unchanged.

Romania recorded the highest annual rate at 6.5%, followed by Lithuania at 6.1% and Bulgaria, which adopted the euro at the start of 2026, at 5.6%. Sweden had the lowest rate at 1.0%, with Hungary and Denmark both at 2.1%.

Among the bloc’s biggest economies, Germany’s rate stood at 3.3%, France’s at 3.4% and Spain’s at 5.0%. Italy saw one of the sharpest moves, with inflation rising to 4.2% from 3.2% in August, more than doubling from 1.7% a year earlier, according to Eunews.

Pressure on the ECB

The figures leave headline inflation well above the European Central Bank’s 2% target and are likely to sharpen debate among policymakers over how to respond to an energy-led price shock. Oil markets remain tight: Saxo Bank noted on Friday that Brent crude was trading above US$105 a barrel amid lingering supply risks around the Strait of Hormuz, while EU natural gas prices were among the commodities up more than 4% on the week.

The relatively contained core reading may give the ECB some room to argue that the spike is concentrated in energy rather than embedded across the economy. But with services inflation also edging higher and price increases spreading across almost every member state, the risk of second-round effects on wages and other costs is likely to stay in focus.

What’s next

Eurostat will publish its flash estimate for October inflation on 4 November, with the full October release due on 18 November. Investors will watch both closely for signs of whether energy costs are starting to stabilise or continue to push consumer prices higher heading into winter.
