The Gross Domestic Product is a comprehensive measure of an overall production and consumption of goods and services. GDP serves as one of the primary measures of overall economic well-being. While GDP announcements generally conform to expectations, unanticipated changes in this metric can move markets.

Robust GDP growth signals a heightened level of economic activity and often a higher demand for the domestic currency. At the same time, economic expansion raises concerns about inflationary pressures which may lead monetary authorities to increase interest rates. Thus better than expected GDP figures are generally bullish for the Euro, while negative readings are generally bearish.

Technically, Gross Domestic Product is calculated in the following way:

GDP = C + I + G + (EX - IM)

where

C = private consumption, I = private investment, G = government expenditure, EX = exports of goods and services, IM = imports of goods and services.

French GDP figures, officially called Quarterly National Accounts, are released quarterly. The headline figures are annualized percentage changes in real and nominal GDP.

CPI is the key gauge for inflation in the Eurozone. Inflation, simply put, is a decline in the purchasing power of the Euro, where each Euro buys fewer goods and services due to higher consumer prices. The index tracks changes in the price of a basket of goods and services that a typical household might purchase. When the CPI is high, it indicates that significant inflationary pressures exist in Eurozone economies. This puts pressure on the European Central Bank to raise interest rates. When CPI comes out lower than expected, the ECB is expected to lower interest rates, or keep them lower, to encourage economic growth. As a rule, the Bank adjusts rates in order to keep Europe consumer price inflation in the 0 to 2 percent range.

The actual inventories of crude oil, gasoline, and distillate, such as jet fuel, as reported on a weekly basis. The numbers are watched closely by the energy markets, and if the results differ greatly from the expected inventory levels, the market can react strongly. The inventory data can be skewed by holidays and seasonal factors. Weekly data can be unreliable and should be viewed as a part of longer-term trends, so a four-week moving average may be more useful.
