Forex industrial chart:-
Forex dealers primarily rely on customers outside of the United States, with upward of 70 percent of all customers coming from more than 140 countries. International customers must go through a stringent account-opening process, which includes depositing money in U.S. banks. These international deposits mean that tens of millions of dollars are flowing to the U.S. banking industry each day. In fact, it is estimated that the banks of forex dealers held $1.3 billion in customer deposits in 2007 alone.
