In December 2016, the Consumer Prices Index (CPI) rose by 0.3% over a month after a stability in the two previous months. Seasonally adjusted, it increased slightly (+0.1%), as in the previous month. Year on year, the CPI accelerated for the second consecutive month (+0.6% after +0.4% in October and +0.5% in November) and have reached its highest increase since May 2014.

The month-on-month increase came from an essentially seasonal rebound in services prices. Energy prices and food prices rose at the same pace as in November. Manufactured product prices were stable after a slight drop in November.
