What is the significance of the Consumer Price Index (CPI)?

The Consumer Price Index (CPI) is significant because it tracks the average change in prices paid by consumers for a specified market basket of goods and services over time. This measurement is essential for understanding inflation, as it reflects how the purchasing power of money changes in relation to the prices of everyday items. By monitoring the CPI, economists, policymakers, and businesses can gauge economic conditions, adjust contracts, and revise cost-of-living adjustments for wages and benefits. This information is crucial for both short-term economic strategies and long-term planning.

Understanding changes in the CPI also helps identify trends in consumer behavior and economic health, allowing governments and financial institutions to make informed decisions regarding monetary policy, interest rates, and economic interventions.
