What is a Commodity
A commodity is a basic good used in commerce that is interchangeable with other commodities of the same type; commodities are most often used as inputs in the production of other goods or services. The quality of a given commodity may differ slightly, but it is essentially uniform across producers. When they are traded on an exchange, commodities must also meet specified minimum standards, also known as a basis grade.
Breaking Down Commodity
The basic idea is that there is little differentiation between a commodity coming from one producer and the same commodity from another producer. A barrel of oil is basically the same product, regardless of the producer. By contrast, for electronics merchandise, the quality and features of a given product may be completely different depending on the producer. Some traditional examples of commodities include grains, gold, beef, oil and natural gas. More recently, the definition has expanded to include financial products, such as foreign currencies and indexes. Technological advances have also led to new types of commodities being exchanged in the marketplace. For example, cell phone minutes and bandwidth.
