In September 2020, the Consumer Price Index (CPI) fell by 0.5% over a month, after –0,1% in August 2020. Service prices declined sharply (–1.5% after +0.3% in August). Those of energy (–0.7% after +0.3%) and food prices (–0.5% after +0.2%) decreased and those of tobacco were stable. Finally, manufactured product prices rebounded strongly (+1.6% after a 1.2% drop in the previous month).

Seasonally adjusted, consumer prices dropped by 0.2% in September, after –0.5% in August.

Year on year, consumer prices were stable, after +0.2% in the previous month. This is the result of a slowdown in service prices and an accentuated decline of those of energy. The prices of tobacco rose less, year on year, than in August (+13.7% after +13.8% in August). Finally, the food prices and those of manufactured product prices evolved at the same rate as in the previous month.

For further information

The COVID-19 health crisis affected the quality of the April, May and June indices (and to a lesser extent March). If the prices collected by INSEE collectors in physical outlets have resumed since 15 June, the structure of household consumption has been modified by the crisis and some few products were still unavailable for sale.
