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.
Cuban convertible peso
On 8 November 2004, the Cuban government withdrew the U.S. dollar from circulation, citing the need to retaliate against further sanctions from the Helms–Burton Act. After a grace period ending on November 14, 2004, a 10% surcharge began to be imposed when converting U.S. dollars into convertible pesos. The change was announced some weeks beforehand, and was extended by the grace period. It has been claimed that it was because the amounts of U.S. dollars being exchanged were more than anticipated. The measure helped the Cuban government collect hard currency.
