The U.S. dollar is the most widely used currency in global commerce. Many commodities are priced in dollars. Much of world trade in goods and services, as well as in financial instruments, is denominated in dollars, even when U.S. residents are not party to either side of the transaction. U.S. Treasury bonds have been the world’s safe-haven asset.

Has the U.S. benefited from the dollar's role in international trade and finance? Is dollar dominance waning under current U.S. policies? If so, what are the likely consequences? Paul Blustein joins EconoFact Chats to discuss these issues.
