What this release is
The Consumer Price Index, or CPI, measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. The year-over-year change, CPI y/y, indicates the rate of inflation. This key economic indicator for the United States is published monthly by the Bureau of Labor Statistics, bls.gov.
Forex traders closely monitor CPI y/y data because it is a primary input for the Federal Reserve’s monetary policy decisions. Persistent inflation pressure can prompt the central bank to adjust interest rates, which directly impacts the attractiveness of the US Dollar to international investors. Higher interest rates typically support a stronger currency.
After past releases, the market’s initial reaction has often focused on the headline year-over-year percentage change. Revisions to previous months’ data can also influence trading sentiment. Given its high typical impact rating, CPI y/y releases frequently lead to significant volatility in USD currency pairs around the time of publication.
