Countries Using the US Dollar

The strength of the American economy is one of the reasons why the U.S. dollar is the world's dominant currency.

The world's most commonly used currency, the dollar is also the world's reserve currency, meaning it's held in large quantities by central banks around the globe. Commonly known as the greenback, the U.S. dollar is also one of the most commonly traded currencies on the foreign exchange market.

Understanding the Countries That Use the US Dollar

The dollar is the official currency of several U.S. territories and other sovereign nations around the world. It's also the quasi-official currency of many other nations that, in addition to their local currency, commonly accept U.S. dollars.

If you're an avid traveler, someone who does business overseas, or an ex-pat, here is a comprehensive list of places around the world that use the greenback as an official currency.

Official Use of the US Dollar

The U.S.'s first Federal Reserve note, a $10 bill, was printed in 1914, one year after the Federal Reserve Bank was created. Although the $1 U.S. note was issued in 1862, it wasn't until 1963 when the $1 Federal Reserve note, featuring George Washington, was issued.

In 1944, the United States and its allies formed the Bretton Woods Agreement to create a new international trade and monetary system. Under the agreement, the International Monetary Fund (IMF) and the World Bank were created, and the U.S. dollar was established as the world's reserve currency. The world's central banks used fixed exchange rates between the U.S. dollar and their currencies.

By 1973, the Bretton Woods Agreement terminated. However, the U.S. dollar remained the reserve currency of many nations. The U.S. dollar remains the primary reserve currency because it is the most traded currency and the United States maintains a strong economy.

More than 65 countries peg their currencies to the U.S. dollar while five U.S. territories and eleven foreign nations use it as their official currency of exchange. The table below provides an overview of the U.S. territories and independent sovereign nations that use the U.S. dollar as their official medium of exchange.

Quasi-Use of the US Dollar

The U.S. dollar is also widely used throughout the world as a quasi-currency of exchange. The U.S. dollar is not only widely accepted for commerce in both Canada and Mexico, but also in a host of tourist destinations including the Bahamas, Barbados, Bermuda, the Cayman Islands, Sint Maarten, St Kitts and Nevis, the ABC Islands of Aruba, Bonaire, Curacao, and the BES Islands including Bonaire, Sint Eustatius, and Saba, collectively known as the Caribbean Netherlands.

The U.S. dollar is also used as a quasi-currency in a variety of popular U.S. retirement destinations such as Belize and Panama, and some areas of Costa Rica. In Panama, for instance, the U.S. dollar is legal tender alongside the national currency, the Balboa, which is also worth US$1. The greenback is also accepted in Nicaragua.

The acceptance of the greenback can be tested in countries such as Myanmar, Cambodia, Liberia, major cities in Vietnam, and the Old City of Jerusalem.

The Bottom Line

The U.S. dollar is the most widely used currency in the world because of its stability and is likely to remain the global currency of choice until perhaps a global digital money system is patently accepted.

Travelers who plan on using the U.S. dollar outside the United States should notify their banking and credit card companies as a precaution to prevent frozen accounts due to suspicious overseas activities. Consumers should also inform their bank and credit cards regarding any foreign currency transaction fees.
