In April 2018, the Consumer Prices Index (CPI) decelerated to +0.2% over one month, after a rebound in March (+1.0%). This slowdown resulted from those, marked and seasonal, in "manufactured product" prices (+0.1% after +2.1%) after a rebound in March due to the end of winter sales. The prices of services (+0.1% after +0.4%) and food (+0.1% after +0.4%) rose less than in March too. On the other hand, energy prices sharply rebounded (+0.9% after −0.7%) in the wake of petroleum product prices.

Seasonally adjusted, consumer prices slowed down: +0.1% after a +0.5% rebound in March.
