Simple Definition

Consumer Price Index. Measures how much prices are rising (inflation).

Why It Matters

CPI is the inflation number that moves markets. A higher-than-expected CPI means the Fed might raise rates, which usually tanks stocks. The monthly CPI release is one of the most market-moving events on the economic calendar.

Key Points

  • CPI measures a basket of goods: food, housing, gas, healthcare, etc.
  • Core CPI excludes food and energy - it's what the Fed watches most closely
  • The Fed targets 2% annual inflation - CPI tells us if we're above or below
