In January 2020, consumer prices increased by 1.5% year on yearConsumer price index - provisional results - January 2020
These provisional results are only preliminary data. Accordingly, they should not be used for contractual revaluations. The indices published here are based on a limited set of price observations and from estimates of some rates of change for fares which are not yet available. The complete results will be published on 20 February 2020.
From the provisional index of January 2020, published on 31 January 2020, scanner data from supermarkets and hypermarkets replace price collection in outlets made by INSEE collectors in these forms of sales for manufactured food products and cleaning and personal care products. Additional information regarding this change is available in the "For further information" section.
Over a year, the Consumer Price Index (CPI) should rise by 1.5% in January 2020, as in the previous month, according to the provisional estimate made at the end of the month. The inflation should be stable: the acceleration in energy prices should be offset by a lesser dynamism in service, food and tobacco prices and a slightly more marked drop in the prices of manufactured goods.
Over one month, consumer prices should fall by 0.4%, after +0.4% in the previous month. Manufactured product prices should drop sharply due to winter sales and those of energy should edge down in the wake of petroleum product prices. Service prices should fall back in January, due to a seasonal downturn in transport service prices. Moreover, food prices should rise less than in the previous month. Finally, tobacco prices should increase slightly.
Year on year, the Harmonised Index of Consumer Prices should rise by 1.6%, as in December. Over one month, it should fall back by 0.5%, after +0.5% in the previous month.

The Harmonised Index of Consumer Prices (HICP) is designed for comparison of consumer price inflation between Members States of the European Union. It is computed for all households in France except Mayotte.
- Scanner data are the data recorded by retailers during consumer purchases. These data sent daily by large retailers to INSEE include, for each item sold in an outlet on a given day, the quantity of items sold and the sale price.
