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.
Central Bank of Curaçao and Sint Maarten
The Central Bank of Curaçao and Sint Maarten (, previously the "Bank of the Netherlands Antilles") is the central bank for the Netherlands Antillean guilder and administers the monetary policy of Curaçao and Sint Maarten. The bank dates to 1828 making it the oldest central bank in the Americas.
