The Commodity Price Index (CPI) is a price index that tracks the prices of commodities, primarily agricultural products and mineral resources, traded in bulk. This index serves as a vital tool for understanding and predicting economic fluctuations.
Historical Context
Commodity price indices have been tracked since the early 20th century as part of efforts to understand the broader economic landscape. The indices emerged from the need to measure price changes in raw materials and inputs essential for various industries.
Types of Commodity Price Indices
- Agricultural Commodity Index: Tracks prices of agricultural products like wheat, corn, coffee, and cotton.
- Mineral Commodity Index: Tracks prices of minerals such as gold, silver, iron ore, and copper.
- Energy Commodity Index: Tracks prices of energy sources such as crude oil, natural gas, and coal.
Key Events and Data Tracking
- 1929: The Great Depression highlighted the need for systematic tracking of commodity prices.
- 1973: The Oil Crisis underscored the importance of energy commodity prices.
- 2008: The Global Financial Crisis showcased the interconnectedness of commodity prices with financial markets.
Detailed Explanations
Calculating Commodity Price Index
The formula for calculating a commodity price index generally follows the weighted average approach:
where:
- \( P_t \) = Price of commodity at time \( t \)
- \( Q_t \) = Quantity of commodity at time \( t \)
- \( P_0 \) = Base period price

Importance and Applicability
- Economic Indicators: CPIs are leading indicators of inflation and economic health.
- Policy Making: Governments and central banks use CPIs to formulate monetary policies.
- Investment Decisions: Investors use CPIs to make informed decisions in commodity markets.
Examples and Use Cases
