In December 2018, the Consumer Prices Index (CPI) was stable over a month, after a 0.2% downturn in November. The sharp drop in energy prices (−2.4% after −0.7%) and the downturn in those of manufactured products (−0.2% after +0.1%) were indeed offset by a rebound in the prices of services (+0.4% after −0.3%) and food (+0.6% after −0.2%).

Seasonally adjusted, consumer prices edged down by 0.2% over a month, after a 0.1% downturn in November.

Year on year, consumer prices slowed down for the second consecutive month: +1.6% in December after +1.9% in November and +2.2% in October. This drop in inflation came from a year-on-year slowdown in energy, services and tobacco prices and a larger drop in manufactured product prices. Contrariwise, food prices accelerated.
