Role of the US Dollar in the Forex Market

The US dollar is the dominant currency in the foreign exchange market. According to data from the Bank for International Settlements (BIS), the US dollar is involved in roughly 88% of all forex transactions globally.

This dominance exists because:

  • The United States has the world’s largest economy.
  • Many global commodities are priced in US dollars.
  • International trade and finance frequently rely on USD as a settlement currency.
  • The US Treasury market is one of the largest and most liquid financial markets in the world.

As a result, shifts in the value of the US dollar can have widespread effects across the global financial system.
