French Inflation Hits 3.4% in October as Energy Prices Accelerate to 24.1%
Key Facts
France’s consumer price index rose 3.4% year on year in October 2026, compared with 3.1% in September, according to final results published by the National Institute of Statistics and Economic Studies (INSEE) on November 13. On a monthly basis, the index rose 0.4% after falling 0.3% in the previous month. The annual increase came as energy prices continued to accelerate, rising 24.1% in the year to October. The data also showed core inflation rising to 1.7% from 1.5%, indicating faster increases across some price components outside energy. Trends across the basket diverged, with services and transport inflation accelerating while food price increases slowed.
Energy inflation accelerated for a fourth consecutive month, from 16.7% in August to 21.3% in September and then 24.1% in October, according to INSEE. Within this component, petroleum product prices rose 38.5% year on year in October, while gas prices increased 27.1% and electricity prices 2.7%. The increases in petroleum products and gas were larger than their September rates, while electricity price growth also accelerated compared with the same month. The divergence shows that energy price pressure was not limited to transport fuels, but also included gas and electricity. Energy inflation, meanwhile, remained the fastest rising component among those reported in the data.
Services prices rose 2.6% year on year in October, compared with 2.4% in September and 1.9% in August, according to the institute’s data. Within services, transport inflation accelerated to 7.4% from 5.1% in the previous month. INSEE attributed the acceleration mainly to air transport prices, which rose 14.4% year on year in October, after 10.0% in September. This means the increase in services prices widened alongside rising energy prices, with air transport standing out within the transport data. The three-month trend points to a gradual acceleration in services inflation, alongside a larger jump in some transport costs.
By contrast, food price increases slowed to 1.2% year on year in October, compared with 1.4% in September. Manufactured product prices rose 0.2% during the month, but remained 0.2% below their level a year earlier. The annual decline in these prices had been 0.3% in September, according to INSEE. This divergence between food and manufactured products on one side, and energy and services on the other, shows differing price trends within the consumer basket. The monthly increase in manufactured product prices also did not prevent them from continuing to fall year on year.
France’s consumer price index differs from the Harmonised Index of Consumer Prices (HICP), which is used to compare countries across the European Union. INSEE’s preliminary estimate for October had put the HICP increase at 3.8% year on year, compared with 3.4% in September, and a monthly increase of 0.4% after a 0.3% decline in the previous month. The final result in the November 13 release, however, concerns France’s consumer price index, which recorded 3.4% year on year in October. In September data, the gap between the annual change in the HICP and the consumer price index was 0.34 percentage points, according to the institute. The figures therefore reflect different measures, and one is not an update of the other.
September data provide context for the earlier acceleration: annual inflation rose to 3.1% from 2.4% in August, while energy prices jumped 21.3% after 16.7% in August and 12.6% in July. On a monthly basis, the index fell 0.3% in September after rising 0.7% in August, amid a seasonal 1.4% monthly drop in services prices. France’s unemployment rate was 8.2% in the third quarter of 2026, up 0.4 points year on year, according to INSEE. These figures place price developments in a broader economic context, but do not change what October’s release showed: an acceleration in both annual and monthly inflation. The available facts do not include a documented measure of the likelihood of European Central Bank action in December.
INSEE scheduled the release of its preliminary estimate of November inflation for November 27, 2026, at 08:45. The next release is set to provide a preliminary reading for the month, following the final October results published on November 13. The new reading will allow comparison of the index’s trajectory after its annual increase to 3.4% in October and its monthly rebound to a 0.4% rise. Its data will also show whether trends in components that stood out in October, including energy, services and food, continued in the following month. The announced date is the institute’s available timetable; the facts do not include subsequent figures for November inflation.
