In September 2025, consumer prices fell by 1.0% over one month and rose by 1.2% year on year Consumer price index - final results - September 2025

In September 2025, the Consumer Price Index (CPI) decreased by 1.0% over one month, after +0.4% in August. This fall in prices was mainly due to the sharp seasonal downturn in services prices (‑1.9% after +0.2%) and more specifically in those of “other services” (‑1.9% after +0.8%) which include accommodation services in particular, and of transport services (‑13.5% after ‑4.1%). Food prices also decreased (‑0.2% after +0.3%) while they slowed down for manufactured products (+0.4% after +1.3%) and were stable again for tobacco.

Seasonally adjusted, consumer prices were stable again in September 2025.

Year on year, consumer prices went up by 1.2% in September 2025, after +0.9% in August. This rise in inflation was explained by an acceleration in services prices (+2.4% after +2.1%) and a smaller decline in those of energy (‑4.4 % after ‑6.2%). Prices of food accelerated slightly (+1.7 % after +1.6%) as those of tobacco (+4.1 % after +4.0%). Conversely, prices of manufactured products fell slightly faster than in August (‑0.4 % after ‑0.3%).

Year on year, core inflation stood at +1.3% in September 2025, after +1.2% in August.

The Harmonised Index of Consumer Prices (HICP) decreased by 1.1% over one month, after +0.5% in August. Year on year, it rose by 1.1%, after +0.8% in August.

Year on year, the prices of services rose by 2.4%, after +2.1% in August.

Inflation in communication services fell less sharply compared with August (‑1.4 % after ‑10.2%) buoyed by the turnaround in mobile telephony prices (+0.6 % after ‑17.1%): over a month, prices rose in September, after falling sharply last year.

Prices of health services accelerated over a year (+2.6% after +1.6%) mainly due to a base effect on paramedical services, which showed a sharp one-month decline in September 2024.

Those of rent, water and household refuse collection rose at the same rate over the year as in August (+2.5%).

The prices of “other services” slowed down slightly over a year (+3.0% after +3.2%), due to a slowdown in insurance services prices (+7.3% after +8.3%) and in those of accommodation services (+3.4% after +4.9%). Prices of social protection (child care services, retirement homes for elderly persons and residences for disabled persons, services to maintain people in their private homes) slowed down too (+3.8% after +4.0%). Conversely, prices of recreational and cultural services accelerated (+2.5% after +2.1%). Prices of catering services rose at the same rate as in August (+2.0%).

Over one year, prices of transport services fell a little more sharply than in August (‑2.0% after ‑1.9%), driven by air transport prices (‑3.7% after being stable). In contrast, prices of transport by train (‑0.6 % after ‑2.3%) and by road (‑0.2 % after ‑2.6%) fell less markedly than in August: last month, the year-on-year change was affected by the temporary rise in prices a year earlier during the Paris Olympic and Paralympic Games.

Year on year, prices of energy fell by 4.4% in September 2025, after ‑6.2% in August.

Over a year, prices of petroleum products rebounded (+0.2% after ‑3.6%), due to a lower fall in those of petrol (‑0.4% after ‑5.1%) and liquid fuels (‑2.7% after ‑3.4%) and to the rebound in diesel prices (+0.7% after ‑2.9%).

Gas prices slowed down slightly (+6.4% after +6.5%).

Prices of electricity fell at a slightly faster rate than in August (‑13.7 % after ‑13.6%).

Year-on-year, food prices accelerated slightly compared with August (+1.7% after +1.6%).

The inflation of food excluding fresh product rose slightly (+1.7% after +1.6%). This is mainly explained by the acceleration in prices of meat (+1.8% after +1.3%), of alcoholic beverages (+0.4% after +0.2%), of bread and cereals (+0.9% after +0.7%) and of non-alcoholic beverages (+9.5% after +9.1%). The prices of milk, cheese and eggs accelerated slightly (+0.4% after +0.3%). On the other hand, those of sugar, jam, honey, chocolate and confectionery slowed down over a year (+5.4% after +6.1%).

The prices of fresh products decelerated slightly over a year (+1.6% after +1.7%) held back by fresh fruits prices (+2.4% after +4.4%). Conversely, prices of fresh fish (+4.1% after +2.3%) and of fresh vegetables (+2.6% after +1.7%) accelerated.

Year on year, the prices of manufactured products fell by 0.4% in September after ‑0.3% in August.

The prices of clothing and footwear slowed again over a year (+0.6% after +1.4%).

“Other manufactured products” prices fell at the same rate as in August (‑0.2%). The acceleration in vehicle prices (+0.9% after +0.5%) and the less marked fall in prices of “other appliances, articles and products for personal care” (‑0.6 % after ‑1.2%) were offset by a sharper fall in prices of major household appliances (‑3.2 % after ‑1.2%) and, to a lesser extent, of furniture and furnishings (‑0.4 % after ‑0.2%).

Over a year, prices of health products decreased at the same rate than in August (‑2.1%).

Compared to the provisional estimates published on 30 September 2025, both month-on-month and year-on-year changes in CPI and HICP have been confirmed.
