consumer price index
- A broad measure of inflation or deflation published by the U.S. Bureau of Labor Statistics. The Bureau tracks a variety of different consumer products at the retail level and uses this information to calculate the percentage numbers that go into the index. Products chosen tend to be consistent from one year to the next but are weighted according to their perceived importance. Inflation can negatively affect the value of the dollar if it gets too high. Forex traders may use the consumer price index as one of many tools for gauging inflation trends.
