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 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. GDP announcements generally conform to expectations as the number comes out after most production figures that lead to overall GDP have already been released. Although releases that are out of line with expectations are rare, unanticipated GDP growth can move markets simply because of its significance as an economic indicator.
