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.
