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.
Eastern Caribbean dollar
In 1958, the West Indies Federation was established and the BWI$ was its currency. However, although Jamaica (including the Cayman Islands and the Turks and Caicos Islands) was part of the West Indies Federation, it retained the Jamaican pound, despite adopting the BWI$ as legal tender from 1954. Jamaica, the Cayman Islands, and the Turks and Caicos Islands were already long established users of the sterling accounts system of pounds, shillings, and pence.
