Caribbean guilder
The Netherlands Antillean guilder will continue to circulate and plans to implement the Caribbean guilder will not be finalized until the islands' Central Bank situation is resolved. The new currency will be abbreviated CMg (for Curacao, Sint Maarten guilder) and would be pegged to the United States dollar at the same exchange rate as the Netherlands Antillean guilder (1 USD = 1.79 NAg = 1.79 CMg). As the BES islands (Bonaire, Sint Eustatius and Saba) adopted the U.S. dollar directly on 1 January 2011, the introduction of the CMg would mean the end of the circulation of the Netherlands Antillean guilder.
United States dollar
Since the suspension in 1971 of convertibility of paper U.S. currency into any precious metal, the U.S. dollar is, "de facto", fiat money. As it is the most used in international transactions, the U.S. dollar is the world's primary reserve currency. Several countries use it as their official currency, and in many others it is the "de facto" currency. Besides the United States, it is also used as the sole currency in two British Overseas Territories in the Caribbean: the British Virgin Islands and Turks and Caicos Islands. A few countries use the Federal Reserve Notes for paper money, while still minting their own coins, or also accept U.S. dollar coins (such as the Sacagawea or presidential dollar). As of June 27, 2018, there are approximately $1.67 trillion in circulation, of which $1.62 trillion is in Federal Reserve notes (the remaining $50 billion is in the form of coins).
