Forex (Foreign Exchange), the largest and most liquid global financial market, provides a venue to trade and exchange currency. The global economy relies on currency to conduct trade transactions with other nations, and the forex market facilitates this trade.
Forex transactions occur around the clock in all major global financial centers, providing an active trading opportunity 24 hours a day. The forex market determines foreign currency values based on supply and demand; all trades occur at market price, or spot price.
Furthermore, when countries exchange goods or services for their respective currency (i.e., importing or exporting), the buyer must send or receive a currency exchange in addition to the product itself—this creates continuous trading activity in the forex market.
Global Importance of Forex Market
According to the Bank of International Settlements, it is estimated that trillions of dollars worth of currency are traded per day on the forex market. Thus the importance of this financial system to the global economy is immeasurable (and still growing).
There are many types of market participants in the forex market (from the Reserve Bank of India to the Central Bank of Japan to multinational companies and financial institutions to individual traders) who all have an impact on the value of currencies based on economic activity, geopolitical events, and trader sentiment.
Understanding how the forex market operates will lay the groundwork for exploring the structure of the forex market as well as the key components and operations of this important market today.
How the Forex Market Has Changed
The forex market has undergone tremendous transformation from its primitive beginnings in barter and metal-based trade to a computerized network of global markets where forex transactions are conducted electronically.
The modern system of currency exchange was not created until the 1970's when floating exchange rates, or where currency values are determined by market forces and no longer by set standards, were adopted replacing the previous traditional system.
Expansion Through Technology
This shift led to an expanded forex market which was due in part to advancements in technology and communication. Major financial centres such as New York, London and Tokyo became the leading centres of currency trade.
With the world's financial centres operating in different time zones, they provided the opportunity for the forex market to remain active continuously. The International Monetary Fund has helped provide stability and oversight of the global economy and the trends that drive it.
Conversion to Electronic Trading Platforms
Electronic trading systems transformed the way currencies are traded. Previously, currency trades were conducted over the phone between banks.
Now the use of electronic platforms allows traders to execute their trades in a matter of seconds.
OTC Market Structure
The majority of Forex trading is executed through an OVER-THE-COUNTER (OTC) MARKET. This means we do not have a centralized marketplace in which participants can see each other.
- Transactions occur directly between market participants
- All participants are connected through a GLOBAL NETWORK
- Major financial institutions such as BANKS and CORPORATIONS dominate trading
How Currency Is Quoted
Foreign Exchange prices can change very quickly due to MARKET ACTIVITY. How fast prices change is greatly influenced by factors including INFLATION, ECONOMIC GROWTH, and MONETARY POLICY DECISIONS.
Therefore, Foreign Exchange is a very Active MARKETPLACE to trade.
Participants in the Foreign Exchange Market
The Foreign Exchange Market is made up of a number of different types of participants. Here are some examples:
- Central Banks - responsible for their country's monetary policies
- Commercial Banks - buy and sell currencies on behalf of their clients
- Corporations - use the Foreign Exchange Market to facilitate INTERNATIONAL TRADE
- Individual Retail Traders - buy or sell currencies through an ONLINE TRADING PLATFORM
These types of participants continuously interact with one another to create a very complicated, yet highly EFFICIENT, foreign exchange trading system by trading currencies around the WORLD 24 HOURS A DAY, EVERY DAY.
Dominant Currency Pairs in the Forex Market
There are selected currency pairs in the forex market that play an integral role in the overall exchange of currencies in the forex market. These currency pairs are referred to as major currency pairs.
Almost all major currency pairs contain the US dollar, which signifies its position as the world's reserve currency. Therefore, the value of USD is largely influenced by decisions made by central banking institutions such as the Federal Reserve (Fed).
Importance of Major Currency Pairs
Major currency pairs in the forex market assist traders with gaining insight into global economic conditions. The price movements of major currency pairs are indicative of changes in interest rates, economic growth rates and geopolitical conditions.
The high degree of liquidity attached to major currency pairs also allows for seamless transactions in the forex market and highlights the importance of the overall structure of the forex market.
Factors Causing Movement of the Forex Market
Movement in currency prices within the forex market is occurring continually and currency prices are constantly being adjusted based on numerous economic and geopolitical factors.
Economic changes; political developments; and global events are just a few of the factors that influence currency prices and movement in the forex market.
Role of Central Banks
The central banking systems in several countries including the Bank of England and the European Central Bank, utilize monetary policy to influence currency value.
Decisions made related to interest rate policy actions; inflation targeting; and money supply have a direct impact on currency performance.
Economic Indicators
Economic data reports including employment; inflation; and GDP growth, are the major drivers of currency movement.
- Strong economic performance increases currency demand
- Weak economic performance decreases currency demand
- Investor confidence influences currency appreciation or depreciation
Political Events
Political stability greatly influences the strength of a currency relative to other currencies. Elections, policy changes, and conflicts can create uncertainty in the market.
- Interest rate decisions
