French consumer prices rise 3.1% on the year in September, final figure up from 3.0%
INSEE's final results raise its provisional 3.0% estimate to 3.1%, with core inflation, services and food all accelerating and energy rising again.
France's statistics institute INSEE published its final consumer price index for September on 15 October 2026. Consumer prices were 3.1% higher than a year earlier, up from 2.4% in August and above the 3.0% in its provisional estimate of 30 September.
What INSEE highlighted
INSEE's summary lists five points: a rise in core inflation, a further acceleration in energy prices, higher services inflation, higher food inflation, and a smaller fall in manufactured goods prices. Energy was the main force behind the increase, with gas and electricity both rising faster than in August.
Reading it
A revision of 0.1 point between the provisional and the final figure is small, but it moved in the direction of the rise, which matters for the euro area's total. France's final figure of 3.1% sits between Germany's 3.3% (report) and the euro area's 3.8% (report). The gap between countries shows how much the energy shock has hit some economies more than others.
