World currency

The U.S. dollar (top) and the euro are by far the most used currencies in terms of global reserves.

In international finance, a world currency, supranational currency, or global currency is a currency that would be transacted internationally, with no set borders. The US dollar served as the global reserve currency since the Bretton Woods Agreements, but is no longer the sole global reserve since 1971 and its uncoupling from gold.
