How Forex Became the $7 Trillion Engine Behind Global Trade

In the vast universe of global financial markets, few sectors compare to the scale, speed, and strategic influence of the foreign exchange market, commonly known as Forex. With daily trading volumes surpassing $7 trillion, Forex dwarfs the world’s stock, bond, and commodities markets combined. Yet for many outside the finance world, it remains a mystery.

So why does Forex continue to command such dominance in the global economy? The answer lies in its unmatched liquidity, round-the-clock operation, critical role in global trade, and rising appeal among institutional and retail investors alike. At the heart of international commerce, government policy, and speculative investing, Forex is not just relevant—it’s indispensable.

The Sheer Size of the Forex Market

The latest data from the Bank for International Settlements (BIS) pegs daily Forex turnover at more than $7.5 trillion as of 2024, up from $6.6 trillion in 2019. That staggering number reflects not only the immense volume of currency transactions but also the evolving structure of global finance.

Unlike stock markets, which are centralized and tied to country-specific trading hours, the Forex market is decentralized and operates 24 hours a day, five days a week. It spans a global network of banks, brokers, central banks, hedge funds, and retail traders—all exchanging currencies to facilitate trade, travel, investment, or speculation.

The market’s largest trading hubs include:

  • London, accounting for 38% of global volume
  • New York, with around 19%
  • Singapore, Tokyo, and Hong Kong, which collectively add another 25%

These centers ensure liquidity around the clock, with trading volume peaking during London/New York overlap hours—a prime window for volatility and opportunity.

Why Forex Still Matters in 2025

Despite emerging technologies, new asset classes like cryptocurrencies, and changing investor preferences, Forex remains the lifeblood of the global financial system. Here’s why it continues to dominate:

1. Currency Powers Global Trade
Every international transaction—whether it’s oil from Saudi Arabia, electronics from Japan, or wheat from the U.S.—involves currency exchange. The Forex market ensures that cross-border commerce flows smoothly, enabling corporations, exporters, and importers to hedge risks and lock in costs.

2. Central Banks Use Forex as a Tool
National monetary authorities like the Federal Reserve, European Central Bank, and Bank of Japan frequently operate in Forex markets to influence their currencies. They may intervene to stabilize prices, prevent excessive volatility, or respond to inflationary pressures.

3. Speculation Drives Innovation
Hedge funds, proprietary trading firms, and increasingly sophisticated retail investors use Forex to capitalize on price movements driven by interest rate shifts, geopolitical events, inflation data, and economic releases. The speculative side of Forex adds enormous liquidity, tightening spreads and driving technological advancement in trade execution.

4. Forex Enables Capital Flows and Investment
Investors allocating capital internationally—whether buying foreign stocks, bonds, or real estate—must engage in currency exchange. Forex not only supports the mechanics of investing but also helps investors manage exposure to currency risk.

5. Massive Technological Advancements
Modern Forex trading is powered by AI-driven algorithms, lightning-fast execution, and deep liquidity aggregation across platforms. These innovations continue to attract institutional players and retail traders looking for diversification and speed.

The Rise of the Retail Trader

While institutional traders still dominate, retail Forex trading has grown substantially over the last decade, thanks to user-friendly platforms, leverage options, and global internet penetration. Today, over 10 million retail traders participate in the market, accounting for 5–10% of daily volume.

Platforms like MetaTrader 4/5, cTrader, and mobile-friendly brokers have democratized access to Forex. Educational resources, demo accounts, and social trading tools further enhance participation—especially among Gen Z and millennials exploring alternatives to stocks.

However, Forex trading is not without risk. Leverage can amplify both gains and losses, and many retail traders enter the market without fully understanding risk management or macroeconomic analysis. That’s why regulatory oversight has increased in recent years, with authorities tightening rules on margin, transparency, and broker licensing.

How Forex Impacts Your Everyday Life

Even if you’ve never traded a currency pair in your life, the Forex market affects you in real ways:

  • Traveling abroad? Currency conversion rates are set by the Forex market.
  • Buying imported goods? Their prices reflect exchange rate fluctuations.
  • Investing in international stocks or ETFs? Currency strength or weakness can impact your returns.
  • Watching inflation trends? Forex can influence how central banks respond to economic shifts.

Because of this, currency strength often becomes a political talking point. A strong dollar may benefit American travelers and consumers, but it can hurt U.S. exporters. Conversely, a weak dollar helps U.S. goods remain competitive abroad but raises the price of imports at home.

What Drives Forex Markets in 2025

The major forces shaping the currency markets today include:

  • Central bank policy divergence: The Federal Reserve, ECB, and Bank of Japan are pursuing different interest rate paths, creating volatility in USD, EUR, and JPY pairs.
  • Geopolitical uncertainty: Conflicts, trade tensions, and sanctions all trigger swift currency movements.
  • Economic data releases: Employment reports, inflation data, GDP readings, and PMI indices remain core drivers.
  • Commodity price shifts: Currencies of resource-rich nations like Canada (CAD) and Australia (AUD) are tightly correlated with oil and metal prices.
  • AI-driven trading: Algorithms are processing global news and executing trades faster than ever, increasing intraday volatility.

Popular Forex Pairs to Watch

The most traded currency pairs (also known as “major pairs”) include:

  • EUR/USD – the most liquid and widely traded pair
  • USD/JPY – driven by U.S.-Japan rate spreads and geopolitical risk
  • GBP/USD – sensitive to U.K. policy, Brexit developments, and inflation
  • USD/CHF – the “safe haven” pair, often used during global stress
  • AUD/USD and USD/CAD – commodity-driven pairs sensitive to global demand

Each pair has unique characteristics, liquidity patterns, and responses to global news—making Forex analysis both complex and rewarding for dedicated traders.

Forex Remains the Backbone of Global Finance

Despite the rise of digital assets, tokenized economies, and evolving investment platforms, the Forex market is still the beating heart of global finance. Its sheer scale, strategic importance, and non-stop action make it essential to how economies function and investors operate.

Whether you’re a seasoned macro trader or a casual investor, understanding Forex gives you a critical lens on international markets, economic policy, and future financial trends. In a world where everything is interconnected, Forex remains the undisputed king of liquidity and relevance.
