Consumer prices are seen falling 0.1 percent in November compared to the previous month when they expanded 0.1 percent, while rising 0.9 percent from a year ago, matching the pace seen in October.

Helping to keep overall prices in check are those for energy which are seen falling 4.6 percent year-on-year, extending the 5.6 percent decline the previous month. Manufactured goods prices are expected to fall 0.6 percent, as business grapple with weak demand leading to discounting.

Services prices paint a different picture and projected to expand 2.2 percent in November, slightly lower than 2.4 percent in November.

Overall food prices will rise 1.4 percent compared to 1.3 percent in November, as a 2.8 percent drop in fresh food prices offsets a 1.9 percent rise for other food.

The HICP used to standardize comparisons among European economies will fall 0.2 percent in November while gaining 0.8 percent over November of last year.

The consumer price index (CPI) is a measure of the average price level of a fixed basket of goods and services purchased by consumers. Monthly and annual changes in the CPI represent the main rates of inflation. The national CPI is released alongside the HICP, Eurostat's harmonized measure of consumer prices. A flash estimate was released for the first time in January 2016 and is now published towards the end of each reference month.

The consumer price index is the most widely followed indicator of inflation. An investor who understands how inflation influences the markets will benefit over those investors that do not understand the impact. In countries where monetary policy decisions rest on the central bank's inflation target, the rate of inflation directly affects all interest rates charged to business and the consumer. As a member of the European Monetary Union, France's interest rates are set by the European Central Bank.

France like other EMU countries has both a national CPI and a harmonized index of consumer prices (HICP). The HICP is calculated to give a comparable inflation measure for the EMU. Components and weights within the national CPI vary from other countries, reflecting national idiosyncrasies.

Inflation is an increase in the overall prices of goods and services. The relationship between inflation and interest rates is the key to understanding how indicators such as the CPI influence the markets - and your investments. As the rate of inflation changes and as expectations on inflation change, the markets adjust interest rates. The effect ripples across stocks, bonds, commodities, and your portfolio, often in a dramatic fashion.

By tracking inflation, whether high or low, rising or falling, investors can anticipate how different types of investments will perform. Over the long run, the bond market will rally (fall) when increases in the CPI are small (large). The equity market rallies with the bond market because low inflation promises low interest rates and is good for profits.
