Commodity Price Index
A commodity price index tracks price changes across a basket of raw materials, helping gauge input costs and inflation pressure.
Inflation measurement terms for CPI, PPI, PCEPI, commodity price indexes, RPIX, and price levels.
Consumer, Producer, and Commodity Price Indexes covers inflation, disinflation, deflation, price indexes, purchasing power, indexation, real-versus-nominal measures, and inflation expectations used in finance.
Use these pages when price changes affect interest rates, real returns, margins, wages, pensions, contracts, purchasing power, valuation inputs, or monetary-policy expectations. It sits inside Inflation Measurement and Price Indexes, so readers can move up when the broader economics context matters.
Use the table below to choose the narrower economics branch before applying a term to a model, credit view, market interpretation, policy conclusion, or risk review. Move into the term page when the evidence source, calculation, institution, market convention, or risk exposure matters.

Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
