According to the report from Insee, in October 2019, the Consumer Prices Index (CPI) was stable over a month, after a 0.3% downturn in September. This stability resulted from a little increase in manufactured product prices (+0.3% after +1.5%), offset by a drop in services prices (−0.1% after −1.3%) and in food prices (−0.4% after −0.5%). Energy prices were stable over a month, after a 0.3% rise in the previous month. Finally, tobacco prices were unchanged over a month.

Year on year, consumer prices slowed down for the fourth consecutive month: +0.8% in October after +0.9% in September. This slight fall in inflation came from a downturn in energy prices and a slowdown in food prices, partly offset by a lesser drop in those of manufactured products. Finally, services inflation was stable.

Year on year, core inflation increased in October: +1.0% after +0.9% in the previous month. The Harmonised Index of Consumer Prices (HICP) fell over a month anew (−0.1% after −0.4% in September); year on year, it rose by 0.9%, after +1.1% in the previous month.
