In February 2018, the Consumer Prices Index (CPI) was unchanged, following a -0.1% downturn in January. Food prices barely edged down (−0.1%), in the wake of fresh product prices. Those of "manufactured product" decreased again, but less markedly than in January (−0.3% after −2.2%). Services prices slowed down for the second consecutive month (+0.1% after +0.2%). Lastly, energy prices were stable, the decrease in petroleum product prices being offset by a rise in gas and electricity prices.

Seasonally adjusted, consumer prices dropped by 0.3%, after an acceleration to +0.7% in January.

Year on year, consumer prices hardly fell in February 2018: +1.2% after +1.3%. This slight decrease in the year-on-year inflation resulted from a lesser rise in prices of services, food and tobacco. The "manufactured product" prices slightly rose and those of energy were up at the same pace as in the previous month.
