About Inflation Rate (CPI)
The Inflation Rate measures the year-over-year change in the Consumer Price Index (CPI), tracking how fast prices are rising. The Federal Reserve targets 2% annual inflation. Inflation above target erodes purchasing power and may trigger interest rate hikes, while deflation can signal economic weakness.
