PPI, or Producer Price Index, is a measure of the average change in prices received by domestic producers for their goods and services over time. It is a key economic indicator used to track inflation and assess the health of the manufacturing sector. Unlike the Consumer Price Index, which measures the prices paid by consumers, PPI focuses on the prices received by producers, providing valuable insights into the cost of production and potential price changes in the market. This data is collected and published by the Bureau of Labor Statistics, making PPI an essential tool for businesses, policymakers, and economists alike in understanding the current state of the economy.
