France’s consumer price inflation climbed in September, signaling renewed price pressures after months of moderation. The French CPI NSA rose 3.10% year-over-year in September 2026, up from 2.40% in August 2026, according to data updated on 15 October 2026.
The figures are calculated on a year-over-year basis, comparing price levels in each month with the same month a year earlier. The latest reading suggests that, after a softer annual increase in August, inflation regained momentum in September, potentially complicating the outlook for monetary policy and household purchasing power.
The move from 2.40% to 3.10% indicates that the disinflation trend seen earlier in the year may be stalling, drawing attention from investors and policymakers to underlying price dynamics as France heads into the final quarter of 2026.
