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.
International use of the U.S. dollar
Some other countries link their currency to U.S. dollar at a fixed exchange rate. The local currencies of Bermuda and the Bahamas can be freely exchanged at a 1:1 ratio for USD. Argentina used a fixed 1:1 exchange rate between the Argentine peso and the U.S. dollar from 1991 until 2002. The currencies of Barbados and Belize are similarly convertible at an approximate 2:1 ratio. The Netherlands Antillean guilder (and its successor the Caribbean guilder) and the Aruban florin are pegged to the dollar at a fixed rate of 1:1.79. The East Caribbean dollar is pegged to the dollar at a fixed rate of 2.7:1, and is used by all of the countries and territories of the OECS other than the British Virgin Islands. In Lebanon, one dollar is equal to 1500 Lebanese pound, and is used interchangeably with local currency as de facto legal tender. The exchange rate between the Hong Kong dollar and the United States dollar has also been linked since 1983 at HK$7.8/USD, and pataca of Macau, pegged to Hong Kong dollar at MOP1.03/HKD, indirectly linked to the U.S. dollar at roughly MOP8/USD. Several oil-producing Arab countries on the Persian Gulf, including Saudi Arabia, peg their currencies to the dollar, since the dollar is the currency used in the international oil trade.
