What Is Forex and Why Does It Exist?

The Purpose of Forex

The foreign exchange market — forex, or FX — exists to facilitate international trade and investment. When a Japanese automaker sells cars to US dealers, someone has to convert yen to dollars. When a European pension fund buys US treasury bonds, euros need to become dollars. Forex is the infrastructure that makes the global economy possible.

The Scale of the Market

The forex market trades approximately $7.5 trillion per day. That makes it roughly 25 times larger than all global equity markets combined. This liquidity has practical implications: major currency pairs almost never gap, can absorb enormous orders without moving price significantly, and are available to trade 24 hours a day, five days a week.

Who Uses the Forex Market?

The participants are not all trying to profit from price movements. Many are:

• Corporations hedging currency exposure from international revenue
• Central banks managing reserve currency levels and monetary policy
• Banks and financial institutions facilitating client transactions
• Hedge funds and prop traders speculating on rate differentials and macro trends
• Retail traders — a relatively small slice of the total volume

The Retail Trader Position

Retail traders account for less than 5% of total forex volume. This is important to understand. The narrative that retail traders are "moving markets" is largely false. The real forces are institutional — and understanding institutional behavior is core to developing real edge.

The forex market does not exist for you to make money. Understanding this is the first step toward actually making money.
