The U.S. dollar plays a central role in the global economy. In addition to being the most widely used currency in foreign exchange transactions, it represents the largest share in official reserves, international debt securities and loans, cross-border payments, and trade invoicing. The ubiquity of the U.S. dollar in global transactions reflects several key factors, including the depth and liquidity of U.S. capital markets, the size of the U.S. economy, the relatively low cost of converting dollars into other currencies, and an enduring confidence in the U.S. legal system and its institutions.
