An Introduction to Forex Markets

By Sanjesh G. Reddy, AboutForexMarkets Editor & Founder

We have all heard of Wall Street, and for most of us, that is where our knowledge of trading markets begins and ends. However, there are not only many other stock markets around the world, but entirely different types of financial markets — and the largest of them all is the foreign exchange market, commonly known as forex or FX. With an average daily turnover of $9.6 trillion according to the Bank for International Settlements, forex dwarfs the stock market, the bond market, and the commodities market combined.

The forex market is where currencies are bought and sold against one another. Every time you exchange money at an airport or a bank sends a wire transfer overseas, a forex transaction takes place. But the vast majority of forex volume is speculative — traders and institutions buying and selling currency pairs to profit from fluctuations in exchange rates driven by interest rate decisions, economic data, geopolitical events, and market sentiment.

Unlike the stock market, which operates through centralized exchanges like the NYSE or NASDAQ, the forex market is decentralized — it operates through a global network of banks, brokers, and electronic platforms, open 24 hours a day, five days a week. Trading sessions rotate through Sydney, Tokyo, London, and New York, meaning that somewhere in the world, currencies are always being traded. This round-the-clock accessibility is one of the key reasons forex has become so popular with individual traders.

In terms of profitability, there is no other market that offers such enormous potential to make a profit — and make it quickly. The combination of high liquidity, leverage (which allows traders to control large positions with relatively small capital), and constant price movement creates opportunities that other markets simply cannot match. However, this same leverage means losses can accumulate just as rapidly, which is why education, practice with demo accounts, and disciplined strategies are essential before trading with real money.

While trading market popularity comes and goes, the forex market has established itself as a permanent fixture of global finance. With the ability for not only deep-pocketed institutional investors but also individual traders with limited starting capital to participate in this highly liquid and exciting market, forex looks like it is here to stay. The key is approaching it with proper education, realistic expectations, and respect for the risks involved.

Who Trades Forex and Why

The forex market attracts a remarkably diverse set of participants, each trading for different reasons and at vastly different scales. Understanding who these participants are — and why they trade — helps explain the market's enormous volume and provides context for how retail traders fit into the broader ecosystem.

Central Banks and Sovereign Institutions

Central banks are among the most influential forex participants, though their primary goal is not profit. The Federal Reserve, European Central Bank, Bank of Japan, and Bank of England intervene in currency markets to stabilize exchange rates, manage inflation, and implement monetary policy. When the Bank of Japan spent approximately $60 billion defending the yen in 2022 alone (according to Japan's Ministry of Finance), it demonstrated the scale at which central banks operate. Central bank interest rate decisions — such as the Federal Reserve's rate-setting meetings eight times per year — are the single most powerful driver of currency price movements.

Commercial and Investment Banks

The interbank market forms the core of forex trading. According to the 2025 BIS Survey, the top five banks — JPMorgan, Deutsche Bank, Citi, UBS, and HSBC — collectively handle a dominant share of all forex volume. These institutions trade on behalf of clients (corporations, governments, fund managers) and for their own proprietary accounts. The interbank market sets the benchmark exchange rates that trickle down to every other participant, including the spreads quoted by retail brokers.

Hedge Funds and Asset Managers

Institutional investors use forex markets for both speculation and hedging. Hedge funds employing macro strategies — like those pioneered by George Soros, who famously profited $1 billion by shorting the British pound in 1992 — take large directional bets based on macroeconomic analysis. Asset managers with international portfolios hedge currency exposure to protect returns. A U.S. fund holding European stocks, for example, might sell EUR/USD forward to neutralize the risk that a falling euro would erode returns when converting back to dollars.

Multinational Corporations

Companies doing business across borders need forex to convert revenues, pay suppliers, and manage currency risk. Apple, Toyota, and Nestle all manage billions in annual currency exposure. When Boeing sells aircraft to a European airline priced in dollars, the airline needs to buy USD. When Toyota sells cars in the United States but reports earnings in yen, it faces ongoing USD/JPY exposure. Corporate treasury departments often use forward contracts and options to lock in exchange rates months in advance, reducing the uncertainty that currency fluctuations create in financial planning.

Retail Traders

Individual traders accessing the market through online brokers represent approximately 2.5% of total daily volume — roughly $240 billion per day as of the 2025 BIS Survey. While this is a small share of the total market, it represents a significant and growing segment. Retail participation has surged since the early 2000s, driven by the proliferation of online trading platforms, lower minimum deposits (some brokers now accept as little as $25), and educational resources that make the market accessible to anyone with an internet connection. The primary motivation for retail traders is speculative profit, though some also use forex to hedge personal currency exposure — such as expatriates managing income in one currency while expenses are in another.

The Scale of the Forex Market

The 2025 BIS Triennial Central Bank Survey confirmed that global forex turnover reached $9.6 trillion per day in April 2025 — a 28% increase from $7.5 trillion in 2022. To put this in perspective, the entire New York Stock Exchange trades roughly $25 billion per day. The forex market moves that amount every four minutes. This extraordinary liquidity means that large orders can be executed without significantly moving the price, spreads remain tight, and traders can enter and exit positions at virtually any time during the trading week.

The market's participants form a hierarchy. At the top sit the major banks — JPMorgan, Deutsche Bank, Citi, UBS, and HSBC collectively handle a significant share of all forex volume through the interbank market. Below them are hedge funds, pension funds, central banks, and multinational corporations hedging currency exposure. At the base are retail traders — individuals trading through online brokers — who account for approximately 2.5% of total daily volume. Despite this small share, the retail forex market still represents roughly $240 billion in daily activity.

How the Forex Market Is Structured

Unlike stock markets that operate through centralized exchanges, forex is an over-the-counter (OTC) market — trades occur directly between parties through a global electronic network rather than on a single exchange floor. This decentralized structure is what enables 24-hour trading: as the Sydney session closes, Tokyo is in full swing; as Tokyo winds down, London opens; and as London closes, New York carries trading into the evening before Sydney opens again. This continuous rotation means that currency prices respond to economic data, central bank announcements, and geopolitical events in real time, around the clock.

The major trading sessions overlap at key times that produce the highest liquidity and tightest spreads. The London-New York overlap (8:00 AM to 12:00 PM EST) is the most active period, handling approximately 50% of all daily forex volume. The Tokyo-London overlap and the Sydney-Tokyo overlap are also active periods. Traders who focus their activity on these high-liquidity windows generally experience better execution and lower trading costs.

Currency trading is always done in pairs — you simultaneously buy one currency and sell another. The most traded pairs involve the U.S. dollar, which appears on one side of 89.2% of all forex transactions. The seven major pairs (EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD, and NZD/USD) account for approximately two-thirds of total forex volume. Beyond these, dozens of minor and exotic pairs offer additional trading opportunities, though with wider spreads and less liquidity.

Getting Started: Your First Steps in Forex

If you are considering entering the forex market, the path from complete beginner to competent trader follows a well-established sequence. Rushing through these steps — or skipping them entirely — is the single most common reason that new traders fail. The CFTC, FCA, and ESMA all report that between 70% and 80% of retail forex accounts lose money, and a lack of preparation is a primary contributing factor.

Step 1: Build Your Knowledge Foundation

Before placing a single trade, invest time in understanding how the market works. Learn the mechanics of currency pairs — what base and quote currencies are, how pip values are calculated, and how lot sizes (standard, mini, and micro) determine your position size. Understand how leverage works and why a 50:1 leverage ratio means a 2% adverse move can eliminate your entire margin deposit. Free educational resources from Babypips, broker platforms like IG Academy and FOREX.com's learning center, and the CFTC's forex education center cover these fundamentals comprehensively.

Step 2: Choose a Regulated Broker

Selecting a trustworthy, well-regulated broker is among the most consequential decisions you will make. Only trade with brokers regulated by top-tier authorities: the CFTC and NFA in the United States, the FCA in the United Kingdom, ASIC in Australia, or CySEC in the European Union. These regulators require client fund segregation, negative balance protection, and minimum capital reserves — protections that unregulated or offshore brokers do not provide.

Step 3: Practice with a Demo Account

Open a free demo account and practice trading with virtual money for a minimum of two to three months. Treat the demo capital as if it were real — use proper position sizing, set stop losses on every trade, and keep a detailed journal of your entries, exits, and reasoning. The goal is not just to learn the platform interface but to develop and validate a trading strategy that produces consistent results over a statistically meaningful sample of at least 50 to 100 trades.

Step 4: Start Small with Live Trading

When your demo results demonstrate consistent profitability, fund a live account with money you can genuinely afford to lose entirely. Start with a mini or micro account and trade the smallest position sizes available. The psychological pressure of risking real money is fundamentally different from demo trading, and even experienced demo traders need time to adjust. Many successful traders recommend spending your first live month focused exclusively on execution discipline — following your strategy rules exactly — rather than on profit targets. Increase position sizes gradually as you prove consistency in live conditions.
