What is Forex?
The Ultimate Guide to the Biggest Global Currency Market
what is forex? Have you ever traveled abroad and wondered why you needed to exchange your local currency for another? Who sets those exchange rates? Who controls when and how to buy a certain currency?
At first, I was just as curious as you might be now.
But once I learned about the foreign exchange market (Forex) — and realized just how massive it truly is — everything started to make sense.
In this article, I’ve crafted a complete guide to help you understand the global currency market, how it works, and most importantly, how you can benefit from it — even as a small trader.
Let’s dive in!
What is Forex?
The foreign exchange market (Forex) is the largest financial market in the world. Quite simply, it is the global financial market that allows participants to trade currencies. If you believe one currency will become stronger than another and you’re correct, you can make a profit.
How Big is the Forex Market?
Forex is one of the most actively traded markets globally, with individuals, companies, and banks conducting around $7 trillion in transactions each day.
According to the Triennial BIS Survey from April 2022, the global forex market averaged approximately $7.5 trillion in daily turnover, up from $6.6 trillion in 2019.
Who Are the Main Players in the Forex Market?
Banks
Large international and commercial banks facilitate the majority of forex transactions, providing liquidity to the market.
Commercial Companies
Businesses involved in international trade use forex to exchange currencies for import and export operations.
Central Banks
National central banks (such as the Federal Reserve or the European Central Bank) intervene in the forex market to stabilize or influence their currency’s value.
Investment Management Firms
These firms trade currencies on behalf of clients, often as part of a diversified global portfolio.
Hedge Funds
Hedge funds are major speculative participants in the forex market, seeking to profit from currency movements.
Retail Forex Brokers
Brokers provide individual traders access to the forex market through trading platforms.
Retail Traders (Individual Investors)
Individual traders speculate on currency price movements, often using leverage provided by brokers.
Wealth Funds
These are state-owned investment funds that may participate in the forex market as part of managing national reserves.
Trading Firms
These firms trade the market using their own capital, often with advanced strategies and high-frequency systems.
Who Dominates the Forex Market?
Simply no one, as the forex market isn’t dominated by a single exchange. It involves a global network of computers and brokers from all over the world.
How Does the Forex Market Work?
The forex market is an over-the-counter (OTC) market. Trading happens without a single centralized exchange. Currencies move between those who are trading, although brokers provide the means to do so. A substantial amount of interbank forex trading exists, and this helps determine swings in exchange rates. Large banks trade currencies to hedge, adjust balance sheets, and trade on behalf of clients.
How Does Forex Trading Work?
Forex trading works like any other transaction where you are buying one asset using a currency. In the case of forex, the market price tells a trader how much of one currency is required to purchase another. For example, the current market price of the GBP/USD currency pair shows how many US dollars it would take to buy one pound.
Each currency has its own code — which lets traders quickly identify it as part of a pair. We’ve included codes for some of the most popular currencies below.
Currency Pairs and Forex
The most widely traded currency pairs are the “majors,” which include EUR/USD, USD/JPY, GBP/USD, and USD/CAD. These pairs account for a significant portion of global forex transactions because of their currencies’ economic and political importance. Emerging market currencies such as the Chinese yuan (CNY) and the Indian rupee (INR) have gained more prominence as their economies have grown.
What Does It Mean to Buy or Sell a Currency Pair?
To buy a currency pair means that you expect the price to rise, indicating that the base currency is strengthening relative to the quote currency. To sell a currency pair means that you expect the price to fall, which would happen if the base currency weakened against the quote.
For example, you’d ‘buy’ the GBP/USD pair if you think that the pound will strengthen against the dollar — meaning you’ll need more dollars to buy a single pound. Or, you’d ‘sell’ this pair if you think that the pound will weaken against the dollar — meaning you’ll need fewer dollars to buy a single pound.
Who Trades Currencies?
Currency markets are crucial to a broad range of participants. Any company that buys or sells overseas, for example, will need to exchange one currency for another as part of their daily operation. Central banks can also be active FX traders, as they seek to keep the currencies they are responsible for under control.
The Story Behind Forex
How Did It All Start?
Gold was the key player in the world back in time, and all currencies were somehow connected to precious metals such as gold and silver until the First World War.
After the war started, the system suddenly collapsed and was replaced by the Bretton Woods Agreement during the Great Depression and World War II.
Breton Woods Agreement:
This agreement created two international organizations related to global economic activity: the International Monetary Fund and the International Bank for Reconstruction and Development, commonly known as the World Bank. The Bretton Woods meeting also produced the General Agreement on Tariffs and Trade.
The new system replaced gold with the U.S. dollar as a peg for international currencies. The U.S. government, in turn, promised to back its dollar with equivalent gold reserves. The Bretton Woods currency system was discontinued in 1971, however, when U.S. President Richard Nixon suspended the dollar’s convertibility into gold.
The forex market has undergone significant changes since then, all of them driven by technological advancements, regulatory developments, and economic events. Currencies now have free-floating exchange rates determined by supply and demand in international markets. The U.S. remains the world’s dominant reserve currency despite the many changes since 1971.
The Internet and the Evolution of the Forex Market
The introduction of electronic trading platforms in the 1990s vastly changed the forex market, making it more accessible, efficient, and liquid. Regulatory milestones such as the creation of the European Monetary Union and the launch of the euro in 1999 reshaped the currency landscape. Economic crises like the 2008 global financial crisis, the 2010 European debt crisis, and the early 2020s pandemic also profoundly impacted currency pairs, leading to increased volatility and shifts in the market.
The Main Types of Forex Markets
There are several ways to trade in the forex market, depending on how and when the currencies are exchanged. The most common types are:
-
Spot Market
This is the most basic type of forex trading. Currencies are exchanged immediately at the current market price. It makes up the largest portion of daily trading.
Main participants include banks, brokers, and individual traders. -
Forward Market
In a forward contract, two parties agree to exchange a set amount of currency at a future date and at a specific rate.
These are private, customizable agreements and are not traded on exchanges. -
Futures Market
Similar to forwards, but futures contracts are standardized and traded on regulated exchanges.
This reduces risk, increases liquidity, and ensures transparency. -
Options Market
Currency options give traders the right (but not the obligation) to buy or sell a currency at a set price before a certain date.
They are useful for hedging or speculative strategies. -
Swap Market
A currency swap involves exchanging two currencies now and reversing the trade at a future date.
Used mainly by banks to manage liquidity and hedge currency exposure.
It’s often a combination of a spot trade followed by a forward contract.
