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.
Currencies of the British West Indies
The Eastern Caribbean group comprised Trinidad and Tobago, Barbados, the Windward Islands, and the Leeward Islands. These territories all used sterling coinage in conjunction with a mixture of sterling accounts and Spanish dollar accounts. The private banking sector tended to use Spanish dollar accounts at the fixed exchange rate of $1 = 4s 2d. The Eastern Caribbean group formed a monetary union with British Guiana in 1949 and the currency was known as the British West Indies dollar. Trinidad and Tobago left the arrangement in 1964. A new arrangement came about the following year and the currency was renamed the Eastern Caribbean dollar. British Guiana withdrew from this monetary union in 1966 and Barbados withdrew in 1972.
