How CPI inflation data affects forex

Why inflation reports can move currencies through interest rate expectations.

What is CPI?

CPI stands for Consumer Price Index. It measures changes in consumer prices and is one of the most watched inflation indicators.

Why forex cares

Central banks respond to inflation. If CPI is hotter than expected, markets may price higher interest rates. If CPI cools, rate expectations may fall.

Typical USD reaction

  • Higher-than-forecast CPI can support USD.
  • Lower-than-forecast CPI can weaken USD.
  • Core CPI often matters because it excludes volatile food and energy.
  • Trading caution

    CPI releases can cause very fast moves. Spreads can widen, and the first reaction can reverse.

    Practical use

    Check CPI date, forecast and previous number. After release, compare actual with forecast and watch whether the move holds after the first few minutes.
