Energy prices rose by 24.1% year on year in October, after 21.3% in September.
Consumer prices rose by 3.4% year on year in October 2026 in France, according to the final results published on Friday, November 13, by Insee.
This increase follows a year-on-year rise of 3.1% recorded in September.
The figure is in line with the provisional estimate published at the end of October.
It is the highest level since January 2024.
This acceleration is linked to the rise in energy prices.
This new surge in prices is due to the sharp increase in energy tariffs.
The upward trend continues for the fourth consecutive month.
It is driven by gas and petroleum product prices.
In October 2025, over the same period, inflation stood at 0.9% year on year.
Energy prices were then falling, before the outbreak of the war in the Middle East.
The harmonized consumer price index, which allows comparisons among eurozone countries, rose by 3.7% year on year, after 3.4% in September.
Month on month, this index rose by 0.4%, after a 0.3% decline the previous month.
According to franceinfo with AFP, the 3.4% rate confirms both the provisional estimate from the end of October and the highest level since January 2024; October 2025 inflation is recalled there at 0.9%.
