Understanding the Structure of the Forex Market

The foreign exchange market (forex or FX) is a decentralized global marketplace where currencies are traded. It is the largest financial market in the world, with a daily trading volume exceeding $7 trillion, making it a crucial component of international trade and investment.

This article explores the structure of the forex market, its key participants, and how it compares to other financial markets like stocks and futures.

Stock Market vs. Forex Market: Key Structural Differences

The Centralized Nature of the Stock Market

Stock trading typically occurs on centralized exchanges such as the New York Stock Exchange (NYSE) or NASDAQ. These exchanges operate with a single entity controlling prices and order fulfillment.

• Limited Trading Hours: Stock markets have fixed trading hours, usually from 9:30 AM to 4:00 PM EST.
• Specialists Control Prices: A specialist or market maker facilitates trades, often adjusting spreads to accommodate their own needs.
• Liquidity Constraints: Stock liquidity depends on individual stocks’ popularity and trading volumes.

Because of these factors, stock prices can be manipulated by large players, making trading more challenging for smaller investors.

The Decentralized Nature of Forex Trading

Unlike stock markets, forex trading occurs over the counter (OTC), meaning there is no single price or exchange. Instead, multiple liquidity providers and brokers compete to offer the best prices.

• 24/5 Market: The forex market operates 24 hours a day, five days a week, allowing traders to react instantly to global economic news.
• Decentralized Trading: There is no single exchange, making price manipulation much more difficult.
• High Liquidity: The massive daily volume ensures tight spreads and efficient trade execution.

This decentralized structure offers more transparency, flexibility, and competitive pricing than centralized stock markets.

Hierarchy of the Forex Market

The forex market operates on a tiered structure, which dictates how different participants interact.

1. Interbank Market (Top-Tier Players)

At the top of the hierarchy is the interbank market, consisting of the world’s largest banks and financial institutions.

• Participants trade directly or through electronic brokers like EBS Market and Refinitiv (formerly Reuters Matching).
• The interbank market controls wholesale forex prices, influencing global exchange rates.
• Only institutions with strong credit relationships can access interbank rates.

EBS and Refinitiv specialize in different currency pairs:

• EBS: EUR/USD, USD/JPY, EUR/JPY, EUR/CHF, USD/CHF
• Refinitiv: GBP/USD, EUR/GBP, USD/CAD, AUD/USD, NZD/USD

2. Hedge Funds, Corporations & Retail ECNs (Mid-Tier Participants)

The next level consists of hedge funds, multinational corporations, retail market makers, and ECNs.

• These participants lack direct interbank access, so they execute trades through commercial banks.
• Their forex rates are slightly higher than interbank prices due to added markups.
• They contribute significantly to the overall liquidity of the forex market.

3. Retail Forex Traders (Bottom-Tier Participants)

Retail traders make up the final tier of the forex market.

• They access forex through online brokers and electronic trading platforms.
• Unlike institutional traders, they have limited capital and rely on leverage.
• The rise of retail forex brokers has made currency trading accessible to individual investors.

Thanks to technological advancements, retail traders now have access to professional-level trading tools, education, and strategies once reserved for large institutions.
