France inflation rises to 3.4% in October, up from 3.1%

INSEE's provisional estimate for October 2026 puts consumer price inflation at 3.4% year over year, up from 3.1% in September. The September figure is final, and the October reading is a flash estimate. The institute described the figure this way: “Sur un an, selon l'estimation provisoire réalisée en fin de mois, les prix à la consommation augmenteraient de 3,4 % en octobre 2026, après +3,1 % en septembre.” [On a year-over-year basis, according to the provisional estimate made at the end of the month, consumer prices would rise 3,4 % in October 2026, after +3,1 % in September] (B-NKER translation).

The harmonized index of consumer prices, the measure used for euro area comparisons, climbs to 3.8% year over year in October from 3.4% in September. INSEE said: “Sur un an, l'indice des prix à la consommation harmonisé augmenterait de 3,8 % en octobre 2026, après +3,4 % en septembre.” [On a year-over-year basis, the harmonized consumer price index would rise 3,8 % in October 2026, after +3,4 % in September] (B-NKER translation).
