To use Gold CFD as an example, at the time of writing, to purchase an ounce of Gold you would need to spend 1,200 USD. However, with a leverage rate of up to 1:20 (which means a trader could trade up to 20 times the value of what they deposit), a trader could trade on the full value of an ounce of gold (equivalent to 1,200 USD), for a deposit of just 60 USD.
U.S. President, Richard Nixon is credited with ending the Bretton Woods Accord and fixed rates of exchange, eventually resulting in a free-floating currency system. After the Accord ended in 1971, the Smithsonian Agreement allowed rates to fluctuate by up to ±2%. In 1961–62, the volume of foreign operations by the U.S. Federal Reserve was relatively low. Those involved in controlling exchange rates found the boundaries of the Agreement were not realistic and so ceased this[clarification needed] in March 1973, when sometime afterward[clarification needed] none of the major currencies were maintained with a capacity for conversion to gold,[clarification needed] organizations relied instead on reserves of currency. From 1970 to 1973, the volume of trading in the market increased three-fold. At some time (according to Gandolfo during February–March 1973) some of the markets were "split", and a two-tier currency market[clarification needed] was subsequently introduced, with dual currency rates. This was abolished in March 1974.
