The foreign exchange market (forex, FX, or currency market) is a worldwide decentralized over-the-counter financial market for the trading of currencies. Financial centers 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.
Forex trading is used to speculate on the relative strength of one currency against another. The foreign exchange market is an over-the-counter market, which means that it is a decentralised market with no central exchange.
The primary purpose of the foreign exchange market is to assist international trade and investment, by allowing businesses to convert one currency to another currency. For example, it permits a US business to import European goods and pay Euros, even though the business's income is in US dollars. It also supports speculation, and facilitates the carry trade, in which investors borrow low-yielding currencies and lend (invest in) high-yielding currencies, and which (it has been claimed) may lead to loss of competitiveness in some countries.
In a typical foreign exchange transaction a party purchases a quantity of one currency by paying a quantity of another currency. The modern foreign exchange market started forming during the 1970s when countries gradually switched to floating exchange rates from the previous exchange rate regime, which remained fixed as per the Bretton Woods system.
Who trades currencies, and why?
There are four types of market participants—banks, brokers, customers, and central banks.
* Banks and other financial institutions are the biggest participants. They earn profits by buying and selling currencies from and to each other. Roughly two-thirds of all FX transactions involve banks dealing directly with each other.
* Brokers act as intermediaries between banks. Dealers call them to find out where they can get the best price for currencies. Such arrangements are beneficial since they afford anonymity to the buyer/seller. Brokers earn profit by charging a commission on the transactions they arrange.
* Customers, mainly large companies, require foreign currency in the course of doing business or making investments. Some even have their own trading desks if their requirements are large. Other types of customers are individuals who buy foreign exchange to travel abroad or make purchases in foreign countries.
* Central banks, which act on behalf of their governments, sometimes participate in the FX market to influence the value of their currencies.
Daily turnover in the world's currencies comes from two sources:
* Foreign trade (5%). Companies buy and sell products in foreign countries, plus convert profits from foreign sales into domestic currency.
* Speculation for profit (95%).
Most traders focus on the biggest, most liquid currency pairs, known as "The Majors". These include US Dollar, Japanese Yen, Euro, British Pound, Swiss Franc, Canadian Dollar and Australian Dollar. In fact, more than 85% of daily forex trading happens in the major currency pairs.
The foreign exchange market is unique because of its
* huge trading volume, leading to high liquidity
* geographical dispersion
* continuous operation: 24 hours a day except weekends, ie trading from 20:15 GMT on Sunday until 22:00 GMT Friday
* the variety of factors that affect exchange rates
* the low margins of relative profit compared with other markets of fixed income
* the use of leverage to enhance profit margins with respect to account size
Market size and liquidity
Main foreign exchange market turnover, 1988–2007, measured in billions of USD.
Of the $3.98 trillion daily global turnover, trading in London accounted for around $1.36 trillion, or 34.1% of the total, making London by far the global center for foreign exchange. In second and third places respectively, trading in New York accounted for 16.6%, and Tokyo accounted for 6.0%. In addition to "traditional" turnover, $2.1 trillion was traded in derivatives.
Several other developed countries also permit the trading of FX derivative products (like currency futures and options on currency futures) on their exchanges. All these developed countries already have fully convertible capital accounts. Most emerging countries do not permit FX derivative products on their exchanges in view of prevalent controls on the capital accounts. However, a few select emerging countries (e.g., Korea, South Africa, India) have already successfully experimented with the currency futures exchanges, despite having some controls on the capital account.
FX futures volume has grown rapidly in recent years, and accounts for about 7% of the total foreign exchange market volume, according to The Wall Street Journal Europe (5/5/06, p. 20).
Foreign exchange trading increased by 38% between April 2005 and April 2006 and has more than doubled since 2001. This is largely due to the growing importance of foreign exchange as an asset class and an increase in fund management assets, particularly of hedge funds and pension funds. The diverse selection of execution venues have made it easier for retail traders to trade in the foreign exchange market. In 2006, retail traders constituted over 2% of the whole FX market volumes with an average daily trade volume of over US$50-60 billion (see retail trading platforms). Because foreign exchange is an OTC market where brokers/dealers negotiate directly with one another, there is no central exchange or clearing house. The biggest geographic trading centre is the UK, primarily London, which according to IFSL estimates has increased its share of global turnover in traditional transactions from 31.3% in April 2004 to 34.1% in April 2007. The ten most active traders account for almost 80% of trading volume, according to the 2008 Euromoney FX survey. These large international banks continually provide the market with both bid (buy) and ask (sell) prices. The bid/ask spread is the difference between the price at which a bank or market maker will sell ("ask", or "offer") and the price at which a market taker will buy ("bid") from a wholesale or retail customer. The customer will buy from the market-maker at the higher "ask" price, and will sell at the lower "bid" price, thus giving up the "spread" as the cost of completing the trade. This spread is minimal for actively traded pairs of currencies, usually 0–3 pips. For example, the bid/ask quote of EURUSD might be 1.2200/1.2203 on a retail broker. Minimum trading size for most deals is usually 100,000 units of base currency, which is a standard "lot".
Financial instruments
Spot
A spot transaction is a two-day delivery transaction (except in the case of trades between the US Dollar, Canadian Dollar, Turkish Lira and Russian Ruble, which settle the next business day), as opposed to the futures contracts, which are usually three months. This trade represents a “direct exchange� between two currencies, has the shortest time frame, involves cash rather than a contract; and interest is not included in the agreed-upon transaction. The data for this study come from the spot market. Spot transactions has the second largest turnover by volume after Swap transactions among all FX transactions in the Global FX market. NNM
Forward
One way to deal with the foreign exchange risk is to engage in a forward transaction. In this transaction, money does not actually change hands until some agreed upon future date. A buyer and seller agree on an exchange rate for any date in the future, and the transaction occurs on that date, regardless of what the market rates are then. The duration of the trade can be a one day, a few days, months or years. Usually the date is decided by both parties.
Future
Foreign currency futures are exchange traded forward transactions with standard contract sizes and maturity dates — for example, $1000 for next November at an agreed rate. Futures are standardized and are usually traded on an exchange created for this purpose. The average contract length is roughly 3 months. Futures contracts are usually inclusive of any interest amounts.
Swap
The most common type of forward transaction is the currency swap. In a swap, two parties exchange currencies for a certain length of time and agree to reverse the transaction at a later date. These are not standardized contracts and are not traded through an exchange.
Option
A foreign exchange option (commonly shortened to just FX option) is a derivative where the owner has the right but not the obligation to exchange money denominated in one currency into another currency at a pre-agreed exchange rate on a specified date. The FX options market is the deepest, largest and most liquid market for options of any kind in the world..
