The global forex market is a huge financial marketplace where over $7.5 trillion changes hands every day. This market is bigger than all other markets combined.
At its heart, the forex market is where people exchange national currencies around the world. These exchanges help international trade, investment, and keep the global economy stable.
In this article, we will walk you through this interesting world. We'll explain the unique structure of the market first. Then we'll introduce the different forex market participants, from central banks to regular traders. Finally, we'll look at how everyone works together in the 24-hour market cycle.
To understand the forex market, we need to know its basic features. The forex market works differently from stock or commodity markets, which gives it special patterns and rules.
We will look at how it has no central location, runs all day, and handles huge amounts of money daily. This knowledge is important for anyone who wants to trade currencies or study how they move.
The forex market has no single physical location or central exchange, unlike the New York Stock Exchange. It is what we call an Over-the-Counter (OTC) market.
This means it works as a big electronic network. The network includes banks, financial companies, businesses, and individual traders worldwide who deal directly with each other.
The difference between an OTC market and a centralized exchange matters a lot. Here are the main differences:
Feature | Forex Market (OTC) | Stock Market (Centralized Exchange) |
---|---|---|
Location | Global, decentralized network | Centralized physical or electronic exchange (e.g., NYSE) |
Trading Hours | 24 hours a day, 5 days a week | Fixed daily trading session (e.g., 9:30 AM - 4:00 PM ET) |
Price Setting | Prices quoted by multiple dealers/banks | Single price determined by supply/demand on the exchange |
Regulation | Regulated by various bodies globally | Regulated by a single national authority (e.g., SEC) |
The forex market runs 24 hours a day, five days a week. This happens because trading follows the sun around the globe.
Trading starts in Sydney, moves to Tokyo, then to the major sessions in London, and finally New York. This smooth handoff ensures that a major financial center is always open for business.
The non-stop nature provides constant access and opportunity, which attracts people from every time zone.
The size of the forex market is hard to imagine. About $7.5 trillion is traded daily, {*according to the 2022 Bank for International Settlements (BIS) Triennial Survey*}.
This makes the forex market the biggest and most active financial market in the world. The huge activity allows trades of any size to happen quickly at any time.
The forex market isn't one single group but layers of different participants. Each player has different goals, access levels, and impact on currency prices.
Understanding who does what is very important. It helps explain why prices move as they do and shows the forces behind the charts. Let's start at the top of this hierarchy and work down.
At the top of the forex market is the interbank market. This exclusive club includes the world's largest commercial and investment banks, like JPMorgan Chase, UBS, and Deutsche Bank.
This level forms the backbone of the entire forex system. These major banks create the market by providing the buy and sell prices that determine currency values globally.
They trade currencies for themselves and handle the huge currency exchange needs of their big clients. They handle so much money that their activities basically create the market for everyone else.
Below the interbank market are other major institutional players. While they don't usually make the market, they trade enough money to strongly influence price movements.
These participants use the forex market for many reasons, from carrying out policy to reducing risk and seeking profits.
In recent decades, a new and growing segment has emerged: retail traders. These are individuals who bet on currency movements from their personal accounts.
Technology and the internet have opened up access to the forex market, allowing almost anyone to participate. While one retail trader's money is small, their combined volume is now a noticeable part of the market.
In the past, forex trading was only for large financial institutions. The cost and complexity were too high for individuals.
Online trading platforms changed everything. These platforms gave individuals direct access to market prices and the ability to trade with relatively small amounts of money.
Retail traders access the forex market through forex brokers. These brokers are essential middlemen.
They provide the trading software, access to market prices, and customer support. Brokers make money either through the spread (the difference between buy and sell prices) or by charging a fee on each trade.
There are different types of brokers, such as market makers who take the opposite side of their clients' trades, and ECN/STP brokers who send trades directly to the interbank market. Choosing the right broker is very important for any retail trader.
Retail traders mainly want to make money from changes in currency exchange rates.
One big attraction is leverage, which lets traders control a large position with a small amount of money. This can increase potential profits, but it also increases potential losses.
The 24-hour nature of the market is also appealing, offering flexibility that a traditional stock market can't match.
Now that we know the players, let's look at how the game works. The forex market operates continuously, governed by time zones and currency pricing structure.
Understanding this flow helps identify busy periods and shows how value is expressed in this unique market.
The 24-hour market breaks down into three major trading sessions that overlap.
The day begins with the Asian session, led by Tokyo and Sydney. This session usually has less price movement, with key changes often happening in pairs like USD/JPY and AUD/USD.
As Asia winds down, the European session, dominated by London, begins. London is the world's largest forex trading center, and trading picks up significantly when it opens.
Finally, the North American session, led by New York, opens. This session is heavily influenced by U.S. economic data releases and overlaps with the London session for several hours.
The busiest period in the forex market is the four-hour overlap between the London and New York sessions.
During this time, two of the largest financial centers are operating at once. This creates the highest trading volume, the smallest price spreads, and the greatest price changes of the day.
Many short-term traders focus only on this period, as it often provides the biggest price movements and trading opportunities. The market tends to be quietest after New York closes and before Sydney opens.
Currencies always trade in pairs, such as the Euro and the U.S. Dollar (EUR/USD). The first currency is the “base” currency, and the second is the “quote” currency.
The exchange rate tells you how much of the quote currency you need to buy one unit of the base currency. If EUR/USD is 1.0800, it means one Euro costs 1.08 U.S. Dollars.
Prices show with two numbers: the bid price and the ask price. The bid is the price at which a broker will buy the base currency from you, and the ask is the price at which they will sell it to you. The difference between these two is the “spread,” which is what you pay for the transaction.
The forex market constantly moves, with exchange rates changing every second. These movements aren't random; they come from economic, political, and market sentiment factors.
For any participant, understanding these core drivers helps make sense of why a currency strengthens or weakens.
Scheduled economic reports are a main cause of short-term price changes. These reports show a snapshot of a country's economic health.
Key reports include Gross Domestic Product (GDP), the Consumer Price Index (CPI) for inflation, employment data (like the U.S. Non-Farm Payrolls), and retail sales figures. A stronger-than-expected report typically strengthens a country's currency, while a weaker report weakens it.
The policies and statements of central banks are probably the most powerful long-term driver of currency values.
Decisions on interest rates are most important. Higher interest rates tend to attract foreign investment, increasing demand for and the value of the currency.
Equally important are the future outlooks provided by central bank leaders. Their comments on the economic future and possible policy changes can shape market expectations and drive trends for months or even years.
Global political stability greatly affects the forex market. Currencies are very sensitive to political tensions, elections, and conflicts.
During uncertain global times, money tends to flow into “safe-haven” currencies like the U.S. Dollar, the Swiss Franc, or the Japanese Yen. On the other hand, the currency of a country with political problems will almost always weaken.
The forex market is much more than just a place to exchange money. It is a complex and dynamic system, the largest and most active financial arena on the planet.
We have seen that its decentralized, over-the-counter structure makes it unique. It operates 24 hours a day, driven by diverse participants, each with different goals—from central banks implementing national policy to individual traders betting on price movements.
Understanding this structure, the players involved, and what drives currency values is the first and most important step for anyone looking to navigate this global marketplace. Learning about forex is an ongoing journey, and a solid foundation is the best asset a trader can have.
