What Is a Commodity?
A commodity is a basic good that buyers treat as essentially interchangeable with other units of the same kind. A barrel of crude oil of a given grade or a bushel of wheat of a given quality is the same product regardless of who produced it, so its price is set mainly by supply and demand rather than by brand or design. Commodities are usually raw materials or primary agricultural products that other businesses process into finished goods, and they are typically traded in large, standardized quantities.
Common Types of Commodities
Commodities are often grouped into broad categories:
- Energy, such as crude oil and natural gas
- Metals, such as gold, silver, and copper
- Agricultural products, such as wheat, corn, coffee, and soybeans
- Livestock, such as cattle and hogs
How Commodities Are Traded
Commodities are bought and sold in two main ways. In the spot market, goods change hands for immediate or near-immediate delivery at the current spot price. In the futures market, buyers and sellers agree today on a price for delivery at a set date in the future through a futures contract traded on an exchange. Many producers and consumers use these contracts to manage risk through hedging, while speculators trade them in hopes of profiting from price changes. Individual investors can also gain exposure through commodity-linked exchange-traded funds or shares of producing companies, though these do not always follow commodity prices closely.
Why Commodities Matter to Investors
Commodity prices are driven by factors such as weather, geopolitical events, production levels, and changes in global demand. Because these forces often differ from those affecting company earnings or bond prices, some investors view commodities as a way to add variety to a portfolio. Commodity prices are also watched as an early signal of inflation, since rising raw material costs can eventually flow through to consumer prices. At the same time, commodity prices can swing sharply, and most commodities do not pay income such as dividends or interest, so any return depends entirely on price movement. Understanding these traits helps investors judge how commodities might fit alongside other holdings.
