What is a Commodity? 

A commodity is a good for which there is demand, but which is supplied without qualitative differentiation across a market. Commodities are substances that come out of the earth and maintain roughly a universal price. It is fungible, i.e. equivalent no matter who produces it.

 

Examples are petroleum, notebook paper, milk or copper. The price of copper is universal, and fluctuates daily based on global supply and demand. Stereo systems, on the other hand, have many aspects of product differentiation, such as the brand, the user interface, the perceived quality etc. And, the more valuable a stereo is perceived to be, the more it will cost.

 

In contrast, one of the characteristics of a commodity good is that its price is determined as a function of its market as a whole. Well-established physical commodities have actively traded spot and derivative markets. Generally, these are basic resources and agricultural products such as iron ore, crude oil, coal, ethanol, salt, sugar, coffee beans, soybeans, aluminium, copper, rice, wheat, gold, silver, palladium, and platinum. Soft commodities are goods that are grown, while hard commodities are the ones that are extracted through mining.

 

There is another important class of energy commodities which includes electricity, gas, coal and oil. Electricity has the particular characteristic that it is either impossible or uneconomical to store, hence, electricity must be consumed as soon as it is produced.

 

Commoditization occurs as a goods or services market loses differentiation across its supply base, often by the diffusion of the intellectual capital necessary to acquire or produce it efficiently. As such, goods that formerly carried premium margins for market participants have become commodities, such as generic pharmaceuticals and silicon chips.

 

Etymology

The word commodity came into use in English in the 15th century, from the French commodité, to a benefit or profit. Going further back, the French word derived from the Latin commoditatem (nominative commoditas) meaning "fitness, adaptation". The Latin root commod- meant variously "appropriate", "proper measure, time or condition" and "advantage, benefit".

Recently, many indistry individuals have begun to identify workers compensation insurance as a commidity.

 

Commodity Trade 

In the original and simplified sense, commodities were things of value, of uniform quality, that were produced in large quantities by many different producers; the items from each different producer were considered equivalent. On a commodity exchange, it is the underlying standard stated in the contract that defines the commodity, not any quality inherent in a specific producer's product.

 

Commodities exchanges include: 

  • Chicago Board of Trade (CBOT)
  • Chicago Mercantile Exchange (CME)
  • Dalian Commodity Exchange (DCE)
  • Euronext.liffe (LIFFE)
  • Kansas City Board of Trade (KCBT)
  • Kuala Lumpur Futures Exchange (KLSE)
  • London Metal Exchange (LME)
  • New York Mercantile Exchange (NYMEX)
  • Multi Commodity Exchange (MCX)
  • International Indonesian Forex Change Market (IIFCM)

 

Markets for trading commodities can be very efficient, particularly if the division into pools matches demand segments. These markets will quickly respond to changes in supply and demand to find an equilibrium price and quantity. In addition, investors can gain passive exposure to the commodity markets through a commodity price index.

 

Inventory data

The inventory of commodities plays a role in the pricing, with low inventories typically leading to more volatile future prices and increasing the risk of a "stock-out" (inventory exhaustion. According to economist theorists, companies receive a convenience yield by holding inventories of certain commodities. Data on inventories of commodities are not available from one common source, although data is available from various sources. Inventory data on 31 commodities was used in a 2006 study on the relationship between inventories and commodity futures risk premiums.

 

Commodities in Marxism

In classical political economy and especially Karl Marx's critique of political economy, a commodity is any good or service produced by human labour and offered as a product for general sale on the market. Some other priced goods are also treated as commodities, e.g. human labor-power, works of art and natural resources, even although they may not be produced specifically for the market, or be non-reproducible goods.

 

Marx's analysis of the commodity is intended to help solve the problem of what establishes the economic value of goods, using the labor theory of value. This problem was extensively debated by Adam Smith, David Ricardo and Karl Rodbertus-Jagetzow among others. Value and price are not equivalent terms in economics, and theorising the specific relationship of value to market price has been a challenge for both liberal and Marxist economists.
