According to the report from Insee, In January 2019, the Consumer Prices Index (CPI) fell back by 0.4% over a month, after a stability in December. The prices of manufactured products sharply dropped, due to the beginning of winter sales (−2.1% after −0.2%) and those of services slowed down (+0.2% after +0.4%). Food prices were also a little less dynamic than in the previous month (+0.5% after +0.6%). Contrariwise, energy prices dropped less sharply than in December (−1.2% after −2.4%), in the wake of petroleum prices. At least, tobacco prices rose by 0.8% after a stability in December.

Seasonally adjusted, consumer prices recovered by 0.2% over a month, after a 0.1% drop in December.

Year on year, consumer prices slowed down for the third consecutive month: +1.2% in January after +1.6% in December. This drop in inflation came from a year-on-year slowdown in energy.
