Brief history of Forex trading

Initially, the value of goods was expressed in terms of other goods, i.e. an economy based on barter between individual market participants. The obvious limitations of such a system encouraged establishing more generally accepted means of exchange at a fairly early stage in history, to set a common benchmark of value. In different economies, everything from teeth to feathers to pretty stones has served this purpose, but soon metals, in particular gold and silver, established themselves as an accepted means of payment as well as a reliable storage of value.

Originally, coins were simply minted from the preferred metal, but in stable political regimes the introduction of a paper form of governmental IOUs (I owe you) gained acceptance during the Middle Ages. Such IOUs, often introduced more successfully through force than persuasion were the basis of modern currencies.

Before World War I, most central banks supported their currencies with convertibility to gold. Although paper money could always be exchanged for gold, in reality this did not occur often, fostering the sometimes disastrous notion that there was not necessarily a need for full cover in the central reserves of the government.
