A global currency refers to the idea of a world monetary system. According to
CBS News, the
euro,
yen,
American dollar and other world currencies would "succeeded by" a global currency and countries would exchange their money for the new currency. In early
September 2009, this was outlined in a report from the
United Nations Conference on Trade and Development. The global currency would be overseen by a
Global Reserve Bank.
