Monthly change: −0.2% in September; year-on-year change: +2.2%

In September 2021, the Consumer Price Index (CPI) fell back by 0.2% over one month, after +0.6% in August. The prices of services contracted sharply (−0.8% after +0.4%), due to the seasonal downturn in the prices of certain tourism-related services. Those of food declined (−0.8% after +0.7%) in the wake of those of fresh food (−3.3% after +3.7%). The prices of tobacco edged down (−0.2% after +0.0%) and those of manufactured goods slowed down (+0.8% after +1.1%). In contrast, the prices of energy accelerated (+1.3% after +0.6%) in link with those of natural and town gas (+6.2% after +3.7%).

Seasonally adjusted, consumer prices fell back by 0.1% in September, after +0.4% in August.

Year on year, consumer prices grew by 2.2%, after +1.9% in August. This increase in inflation resulted from the acceleration in service prices (+1.4% after +0.7%) and energy prices (+14.9% after +12.7%). The prices of manufactured goods (+0.4% after +1.1%), and to a lesser extent food (+1.0% after +1.3%) and tobacco (+4.8% after +5.1%) slowed down.

Decrease in core inflation year on year

Year on year, core inflation dropped in September, down to +1.3%, after +1.5% in August. The Harmonised Index of Consumer Prices (HICP) fell back by 0.2% over one month after +0.7% in the previous month; year-on-year, it increased by 2.7%, after +2.4% in August.

Compared to the provisional estimates published on September 30, 2021, the month-on-month change in CPI and year-on-year and month-on-month changes in HICP have been confirmed. The year-on-year change in CPI has been revised upwards by 0.1 points.

For further information

The price collection carried out by collectors on the field was adjourned with the beginning of lockdown, from the 16th March to the 15th June 2020, in November and December 2020 and progressively since the end of March 2021 until the end of May 2021 in metropolitan France. Despite the introduction of alternative collection methods (price collection online, telephone collection, scanner data), the quality of the indices was affected. Therefore, the level of the indices, the month-on-month rate and particularly the year-on-year rate should be considered cautiously. The missing prices due to a lack of collection or an impossibility to purchase the products were imputed in compliance with Eurostat guidelines. In September 2021, this imputation rate due to Covid-19 is about 2% as in August.
