The foreign exchange market
(forex, FX, or currency market) is a form of exchange for the global
decentralized trading of international currencies. Financial centres around the
world function as anchors of trading between a wide range of different types of
buyers and sellers around the clock, with the exception of weekends. The
foreign exchange market determines the relative values of different currencies.
The foreign exchange market assists international trade and investment by enabling currency conversion. For example, it permits a business in Kenya to import goods from the European Union member states especially Eurozone members and pay Euros, even though its income is in Kenya shillings. It also supports direct speculation in the value of currencies, and the carry trade, speculation based on the interest rate differential between two currencies.
In a typical foreign exchange
transaction, a party purchases some quantity of one currency by paying 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 had
remained fixed.
The foreign exchange market is unique because of the following characteristics:

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,
- 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.
As such, it has been referred to
as the market closest to the ideal of perfect competition, notwithstanding currency
intervention by central banks. According to the Bank for International Settlements,
as of April 2010, average daily turnover in global foreign exchange markets is
estimated at $3.98 trillion, a growth of approximately 20% over the $3.21
trillion daily volume as of April 2007. Some firms specializing on foreign
exchange market had put the average daily turnover in excess of US$4
trillion.
The $3.98 trillion break-down is
as follows:
- $1.490 trillion in spot transactions,
- $475 billion in outright forwards,
- $1.765 trillion in foreign exchange swaps,
- $43 billion currency swaps,
- $207 billion in options and other products.
