Inflation measures the rate at which prices for goods and services increase over time. It’s one of the most important economic indicators for forex traders.

How It’s Measured

  • CPI (Consumer Price Index) — Most common measure
  • Core CPI — Excludes food and energy (more stable)
  • PPI (Producer Price Index) — Wholesale level
