Consumer Price Index

A measure of inflation that tracks the average change in the price of a basket of goods.

Quick answer

The consumer price index measures inflation as the price change of a basket of goods.

Definition

The consumer price index measures how fast the price of a typical basket of goods is rising, which is how inflation is tracked. It is one of the most market-moving releases because central banks set policy partly on it. A hotter CPI reading can push expectations of higher interest rates and move the currency.

How It Works

  • It is the standard inflation gauge
  • Central banks react to its direction
  • A surprise moves rates expectations and the currency
