Inflation Rate (CPI/HICP) (USD)

Measures the year-over-year percentage change in the Consumer Price Index (CPI) or Harmonised Index of Consumer Prices (HICP). Inflation is the single most important factor driving Central Bank policy decisions. If inflation is above target, it suggests the Central Bank will raise interest rates (Hawkish), which is strongly bullish for the currency. If inflation is below target, it suggests rate cuts (Dovish), which is bearish.
