Over a year, the Consumer Price Index (CPI) should slow down in May 2017 (+0,8% after +1.2% in April) according to the provisional estimate made at the end of the month. This drop in year-on-year inflation should come from a marked slowdown in energy prices and a moderate one in food and tobacco prices. Manufactured product prices are set to decrease again, at the same pace as in the previous month. Services prices should grow as much as in April.

Over one month, consumer prices should rise by 0.1%, as in April. This slight increase should be due to a rebound in food prices, offset by a marked drop in energy prices and a slight downturn in these of tobacco. Services prices are set to slow down slightly owing to a downturn in airfares and communications services. Lastly, the rise in manufactured product prices should stay very moderate.

Year on year, the Harmonised Index of Consumer Prices should slow sharply, to +0.9% after +1.4% in the previous month. Over one month, it should be stable, after +0.1% in April.
