In December 2017, the Consumer Prices Index (CPI) gathered pace at +0.3% after +0.1% in November. This sharper rise came from a seasonal rebound in services prices and, in a lesser extent, from that of manufactured product prices. On the other hand, energy prices and tobacco prices slowed down and those of food were stable.

Seasonally adjusted, consumer prices hardly slowed down after a slight acceleration in the previous month: +0.1% after +0.2% in November.
