Commodities are defined as “all goods and products subject to trade.” Generally, they are tangible items rather than digital assets. Crude oil, gold, copper, wheat, cotton, soybeans and coal are examples of commodities. These items are typically raw materials or sometimes intermediate goods used in production.
How Is Commodity Trading Conducted?
Commodities are traded on global exchanges, which are often organized by type—such as agricultural, energy, or metals exchanges. Major markets for commodity trading are centered in countries like the United States and the United Kingdom. For example, crude oil contracts commonly trade on U.S. exchanges, while certain aluminum contracts are listed on U.K. exchanges. Commodity prices are highly volatile because they respond to supply-and-demand fluctuations in production, weather, geopolitics and other factors. That volatility makes exchange values change frequently. Another important feature of commodities is their tradability: they can be bought and sold freely, a characteristic known as liquidity.
Commodity Standards
To be traded as a commodity, a product must meet specific standards. These standards minimize quality differences among items sold at the same price. For instance, while wheat is a commodity, not every variety qualifies; only wheat meeting defined specifications is accepted for commodity trading. Gold is considered a commodity only when its purity typically exceeds 99%. Crude oil is classified into different grades—such as WTI and Brent—each with distinct pricing. Another key concept is the lot size, which denotes the minimum tradable unit. A lot represents one unit of trade: in oil it is expressed in barrels, while for gold and other precious metals it is commonly measured in troy ounces (1 troy ounce = 31.1 grams).
Additional Information About Commodities
Commodities can serve as an investment vehicle. Gold is often viewed as a safe-haven asset and is a preferred choice for many investors seeking stability. Crude oil has also been an important investment asset, although interest declined after the price downturn that began in 2014. Another notable point is that commodity prices tend to follow similar trends to global economic growth—rising with expanding demand during growth periods and softening when economic activity slows.
