Over a year, the Consumer Price Index (CPI) should accelerate sharply in May 2018, to +2.0% after +1.6%, according to the provisional estimate made at the end of the month. This rise in the year-on-year inflation should come from a strong year-on-year acceleration in energy prices, and to a lesser extent, in food product prices. Moreover, manufactured product prices should decline a little less than in the previous month. In contrast, tobacco prices should slow down slightly and the inflation in services should be unchanged.

Over one month, consumer prices should increase a little stronger than in April (+0.4% after 0.2%). This sharper rise should result from those of energy prices, due to the dynamism of petroleum product prices. Food prices should grow more than in the previous month, as manufactured product prices. Services prices should rise at the same pace as in the previous month and those of tobacco should edge down after a stability in April.

Year on year, the Harmonised Index of Consumer Prices should continue to accelerate (+2.3% after +1.8% in April). Over one month, it should rise more strongly too, to +0.4% after +0.2% in April.
