Few data points move markets like inflation. Understanding CPI helps you anticipate some of the year's biggest swings.
What is CPI?
The Consumer Price Index measures how much prices for everyday goods and services have changed. It's the headline gauge of inflation.
Why it matters so much
Inflation drives what central banks do with interest rates. Hotter-than-expected inflation raises the odds of rate hikes; cooler inflation raises the odds of cuts. Since rates drive currencies, CPI surprises can move the dollar, gold, and indices fast.
Expectations are everything
Markets move on the surprise, not the number itself. If CPI comes in exactly as expected, the reaction can be muted; a big miss in either direction can trigger sharp moves.
Watch the forecast versus the actual number on the economic calendar — the gap between them is what drives the move.
How to trade around it
Like other high-impact releases, the safest approach is usually patience: let the initial spike pass and trade the clearer move that follows. ForexBro avoids publishing into these windows by design.
