a party purchases some quantity of one currency by paying for some
quantity of another currency. The modern foreign exchange market began
forming during the 1970s after three decades of government restrictions
on foreign exchange transactions (the Bretton Woods system
of monetary management established the rules for commercial and
financial relations among the world's major industrial states after World War II), when countries gradually switched to floating exchange rates from the previous exchange rate regime, which remained fixed as per the Bretton Woods system. The foreign exchange market is unique because of the following characteristics:
- its huge trading volume representing the largest asset class in the world leading to high liquidity;
- its geographical dispersion;
- its continuous operation: 24 hours a day except weekends, i.e., trading from 22:00 GMT on Sunday (Sydney) until 22:00 GMT Friday (New York);
- the variety of factors that affect exchange rates;
- the low margins of relative profit compared with other markets of fixed income; and
- the use of leverage to enhance profit and loss margins and with respect to account size.
- $1.490 trillion in spot transactions
