Futures exchange

A futures exchange or futures market is a central financial exchange where people can trade standardized futures contracts; that is, a contract to buy specific quantities of a commodity or financial instrument at a specified price with delivery set at a specified time in the future. These types of contracts fall into the category of derivatives. The opposite of the futures market is the spots market, where trades will occur immediately (2 business days) after a transaction agreement has been made, rather than at a predetermined time in the future. Futures instruments are priced according to the movement of the underlying asset (stock, physical commodity, index, etc.). The aforementioned category is named "derivatives" because the value of these instruments are derived from another asset class.

According to The New Palgrave Dictionary of Economics (Newbery 2008), futures markets "provide partial income risk insurance to producers whose output is risky, but very effective insurance to commodity stockholders at remarkably low cost. Speculators absorb some of the risk but hedging appears to drive most commodity markets. The equilibrium futures price can be either below or above the (rationally) expected future price (backwardation or contango)...Rollover hedges can extend insurance from short-horizon contracts over longer periods."

In Ancient Mesopotamia, around 1750 BC, the sixth Babylonian king, Hammurabi, created one of the first legal codes: the Code of Hammurabi. Hammurabi’s Code allowed sales of goods and assets to be delivered for an agreed price, at a future date; required contracts to be in writing and witnessed; and allowed assignment of contracts. The code facilitated the first derivatives, in the form of forward and futures contracts. An active derivatives market existed, with trading carried out at temples.

One of the earliest written records of futures trading is in Aristotle's Politics. He tells the story of Thales, a poor philosopher from Miletus who developed a "financial device, which involves a principle of universal application". Thales used his skill in forecasting and predicted that the olive harvest would be exceptionally good the next autumn. Confident in his prediction, he made agreements with local olive-press owners to deposit his money with them to guarantee him exclusive use of their olive presses when the harvest was ready. Thales successfully negotiated low prices because the harvest was in the future and no one knew whether the harvest would be plentiful or pathetic and because the olive-press owners were willing to hedge against the possibility of a poor yield. When the harvest-time came, and a sharp increase in demand for the use of the olive presses outstripped supply (availability of the presses), he sold his future use contracts of the olive presses at a rate of his choosing, and made a large quantity of money. It should be noted, however, that this is a very loose example of futures trading and, in fact, more closely resembles an option contract, given that Thales was not obliged to use the olive presses if the yield was poor.
