The Raw Materials Price Index (RMPI) measures the change in the price of raw materials purchased by manufacturers for further processing. This year-over-year figure compares the current month's prices to the same month in the previous year, providing a clear picture of long-term inflationary trends in the industrial sector. It is a significant leading indicator of consumer inflation because rising costs for raw materials are often passed on to consumers in the form of higher prices for finished goods. The index covers various commodities, including crude oil, metal ores, and agricultural products.
The index is calculated using a weighted average of price changes for a basket of raw materials. Data is collected through surveys of manufacturers and market price observations for key commodities.
