Monthly change: ‑1.2% in September; year-on-year change: +1.1%

In September 2024, the Consumer Price Index (CPI) decreased by 1.2% over one month, after +0.5% in August, this represents the sharpest monthly fall in prices since the series began in 1990. This decrease in prices was due, on the one hand, to the fall in prices of services (‑2.2% after +0.5%) because of the seasonal effect of the fall in transport prices (‑13.5% after +1.4%), particularly passenger transport by air (‑24.8% after +0.7%), and accommodation services (‑17.2% after +7.2%), marking the return to normal of certain tariffs following the summer holidays and the Olympic and Paralympic Games. On the other hand, prices of energy decreased again (-1.8% after -1.3%) due to the fall in prices of petroleum products (‑3.5% after ‑2.8%). Prices of food slightly decreased over one month (‑0.3% after +0.3%). Conversely, prices of manufactured goods rose but slowed down over the month (+0.5% after +1.4%), like those of clothing and footwear prices (+4.0% after +6.2%). Tobacco prices were stable over one month as in August.

Seasonally adjusted, consumer prices decreased by 0.6% in September 2024 after +0.2% inAugust.

Year on year, consumer prices went up by 1.1% in September 2024, after +1.8% in August. This drop in inflation resulted from the sharp fall back in prices of energy (‑3.3% after +0.4%) and the slowdown in those of services (+2.4% after +3.0%). Year on year, the prices of manufactured products (‑0.3% after ‑0.1%), food (+0.5% after +0.5%) and tobacco (+8.7% after +8.7%) evolved year on year at a rate close to or similar to that of August.

New slowdown in core inflation year on year

Year on year, core inflation slowed down, reaching +1.4% in September 2024, after +1.7% in August.

The Harmonised Index of Consumer Prices (HICP) decreased by 1.3% over one month, after +0.6% in August. Year on year, it slowed down: +1.4% in September 2024, after +2.2% in August.
