Core Inflation
Food and energy costs are genuinely important to households, but they bounce around for reasons that have little to do with the broader economy — a cold snap, a drought, an OPEC supply cut. By removing them, core inflation tries to show the underlying, persistent trend in prices. Central banks pay close attention to this figure because monetary policy works slowly; they care more about where inflation is heading over months and years than about last week's gasoline spike.
Core inflation is typically expressed the same way as headline CPI: a year-over-year or month-over-month percent change. The same statistical agencies that publish headline figures publish core ones alongside them. Traders typically watch whether core inflation is rising, falling, or stuck, since that shapes expectations about future interest-rate decisions. You can see live inflation-related data under economic indicators.
A common confusion is thinking that "lower core inflation" means prices are falling — it does not. Core inflation at, say, 2 % still means prices are rising; they are just rising more slowly than before. That distinction — slower inflation versus actual price declines — is explored in disinflation and deflation. Another nuance: different agencies calculate core differently; some exclude only food and energy, while others use statistical smoothing methods, so always check which definition a headline is using.
