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 peso
In 1993, during the period of economic austerity known as the Special Period, the US dollar was made legal tender to encourage hard currency to enter the economy. The US dollar was the currency used to purchase some non-essential goods and services, such as cosmetics, and even staple kinds of food and drink. In 1994, the convertible peso was introduced at a par with the US dollar. On November 8, 2004, the Cuban government withdrew US dollars from circulation, citing the need to retaliate against further US sanctions.
