loans and money

The foreign exchange market is one of the largest financial markets in the world but it has no exchange. Trades are done by phone or by using computers and it is a 24-hour market. Major foreign exchange centers include London, New York, Tokyo and Singapore. The introduction of the euro seriously reduced the opportunities for foreign exchange traders to make profits as the number of opportunities for cross-currency trades fell.
Trading currencies is arguably one of the most basic trading activities of most large commercial banks. We have already examined ways in which countries can attempt to manage their exchange rates against other currencies. In fundamental terms, however, exchange rates are determined by balance of payment deficits (or surpluses), capital inflows (or outflows) and perceptions of likely future inflation and real interest rates.
