The Euromarket

A major catalyst to the acceleration of Forex trading was the rapid development of the eurodollar market; where US dollars are deposited in banks outside the US. Similarly, Euromarkets are those where assets are deposited outside the currency of origin. The Eurodollar market first came into being in the 1950s when Russia's oil revenue-- all in dollars -- was deposited outside the US in fear of being frozen by US regulators. That gave rise to a vast offshore pool of dollars outside the control of US authorities. The US government imposed laws to restrict dollar lending to foreigners. Euromarkets were particularly attractive because they had far less regulations and offered higher yields. From the late 1980s onwards, US companies began to borrow offshore, finding Euromarkets a beneficial center for holding excess liquidity, providing short-term loans and financing imports and exports.

London was, and remains the principal offshore market. In the 1980s, it became the key center in the Eurodollar market when British banks began lending dollars as an alternative to pounds in order to maintain their leading position in global finance. London's convenient geographical location (operating during Asian and American markets) is also instrumental in preserving its dominance in the Euromarket.
