Over a year, the Consumer Price Index (CPI) should increase by 1.1% in October 2017, after +1.0% in the previous month, according to the provisional estimate made at the end of the month. This third consecutive rise in year-on-year inflation should result from an acceleration in food prices and a lesser drop in manufactured product prices. Energy prices should slow down slightly after two months of sharp acceleration. Services prices should rise at the same pace than in the previous month.

Over one month, consumer prices should recover slightly (+0.1%) after a moderate downturn in September. This drop should come from a rebound in food prices and a lesser fall in services prices. Energy prices should increase at the same pace than in September: a rise in town gas prices should be offset by a slowdown in petroleum product prices. On the other hand, manufactured product prices should decelerate sharply after an increase in September.
