Commodity Exchanges: How They Work

Commodity exchanges are the lifeblood of commodity and indeed futures trading, acting as a portal for buyers and sellers of commodities to get together to exchange their wares. A fundamental requirement for trading commodities, exchanges work relatively seamlessly to facilitate trade, both for price speculators, hedgers and raw materials traders, to ensure a constant supply and demand of commodities matches with a flexible pricing approach that makes the market work for both parties involved. But how exactly do commodity exchanges work?

Commodity Exchanges Defined

A commodity exchange is simply a market, like a stock market, where buyers and sellers can engage in the process of trading commodities. Almost exclusively handled electronically, commodities exchanges give individual investors and private funds alike the chance to engage directly with the market for commodities, to enable speculation on price, speculation on commodity derivatives and even end-user trade in commodity quantities.

Because commodities are by definition generic, prices are defined automatically by the intersect between demand and supply, and the exchanges handle these price movements algorithmically to reflect the true market value for a commodity at a given time. This has a direct bearing on the resultant value in futures contracts for the specified commodity type, given that any rise or fall could be indicative of future movements, and as such makes the commodities exchange an invaluable tool in calculating the value (as distinct from the price) of commodities futures contracts.

Standardisation, Liquidity and the Function of the Exchange

The exchanges operate by virtue of standardisation and liquidity, both of which conditions make it possible to engage in free-flowing commodities trading. Briefly, standardisation is the process whereby all commodities, and indeed all futures contracts, are set up in standard ways such that one lot of commodity is indistinguishable from like-for-like produce. This means that anyone can buy or sell their commodity or futures contract to anyone else, without the need for individual negotiations or due diligence.

Liquidity likewise makes it possible to fill your orders quickly. Because there is such an extensive volume of trade in both commodities and derivatives, it is possible to constantly buy and sell orders of varying types and sizes without the fear of your orders remaining unfilled. This essentially means that the exchange can function as a fluid marketplace for both buyers and sellers, without relying on any laborious matching processes.

The Bigger Picture

The commodities exchange has a significant impact on the wider picture, both for business, traders and economies. On a microeconomic level, commodity price rises cost mean manufacturers have to pay more for their raw materials, although it can also mean that producers are paid more for their commodity – depending on the ratio of manufacturers to suppliers this could turn out to deliver a positive or negative overall result. This can also have a serious impact on inflation (if raw materials are costing more), in addition to its bearing on the profit portions of many of the world’s largest businesses. As such, the exchange plays a crucial economic role.
