According to the report from Insee, over a year, the Consumer Price Index (CPI) should slow down to +0.7% in October 2019, after +0.9% in the previous month. This drop in inflation should result from a downturn in energy prices and from a slowdown in those of food. Manufactured goods prices should drop less than in September and the inflation in services should be unchanged.

Over one month, consumer prices should edge down by 0.1%, after a 0.3% drop in September. Energy prices should be stable, the rise in petroleum product prices being offset by an accentuated decrease in gas prices. Those of services should drop barely after a sharp contraction in September. Finally, food prices should drop at the same pace as in the previous month and those of manufactured goods should slow down.

Year on year, the Harmonised Index of Consumer Prices should slow down to +0.9% after +1.1% in September. Over one month, it should fall by 0.1%, after −0.4% in the previous month.
