Global cooperation, dealing with other countries, getting along with other countries is good, it’s very important. But there is no such thing as a global anthem, a global currency or a global flag. This is the United States of America that I’m representing.
As it happens, there is a global currency.
It’s called the “U.S. dollar.”
Most international trade is priced in dollars. The Bretton Woods international monetary system invested the dollar, which then was defined as and (internationally) was legally convertible to gold at $35/oz, with global currency status. France’s then-finance minister, later its president, Valéry Giscard d’Estaing, called the “reserve currency” status of the dollar — its status, along with gold, as global currency — an “exorbitant privilege.”
By this d’Estaing was alluding to the fact, as summarized at Wikipedia, that “As American economist Barry Eichengreen summarized: ‘It costs only a few cents for the Bureau of Engraving and Printing to produce a $100 bill, but other countries had to pony up $100 of actual goods in order to obtain one.’” That privilege, which made great sense during the period immediately after World War II, became a curse.
In 1971 President Nixon, under the influence of his Svengali-like Treasury Secretary John Connally, “suspend[ed] temporarily the convertibility of the dollar into gold.” That closure proved durable instead of temporary. The dollar became, and remains, the world’s global currency.
