According to a Bank of International Settlements’ report, the global foreign exchange market turnover has 90 percent to some four trillion dollars by April 2010 from 3.3 trillion dollars three years earlier.

(Britain is still the world’s largest foreign exchange (Forex) centre with 36.7 percent of the total trade, followed by The United States, second with 18 percent, and then Japan with six percent.  I wouldn’t even know how to start.)
