As international reserve currency

The U.S. dollar is joined by the world's other major currencies – the euro, pound sterling, Japanese yen and Chinese renminbi – in the currency basket of the special drawing rights of the International Monetary Fund. Central banks worldwide have huge reserves of U.S. dollars in their holdings and are significant buyers of U.S. treasury bills and notes.

Foreign companies, entities, and private individuals hold U.S. dollars in foreign deposit accounts called eurodollars (not to be confused with the euro), which are outside the jurisdiction of the Federal Reserve System. Private individuals also hold dollars outside the banking system mostly in the form of US$100 bills, of which 80% of its supply is held overseas.

The United States Department of the Treasury exercises considerable oversight over the SWIFT financial transfers network, and consequently has a huge sway on the global financial transactions systems, with the ability to impose sanctions on foreign entities and individuals.
