ABOUT INFLATION
What Is Inflation and How Is CPI Used?
Inflation is a sustained increase in the general price level over time. The inflation rate is commonly expressed as the percentage change in the price level during a given period.
The Consumer Price Index (CPI) is one of the most common ways to measure inflation. It tracks changes in the prices of a representative basket of consumer goods and services.
Core inflation is often used to examine more persistent price trends. Because food and energy prices can be affected by seasonal factors and temporary supply shocks, some core measures exclude these volatile components. Definitions vary across countries and institutions.
Inflation data is important for monetary policy, business pricing, wage adjustments, bond markets and household purchasing power. CPI primarily measures household consumption prices and does not represent every price movement across the economy.
