The U.S. Dollar is the official currency of the FSM, no other currency will be accepted. If you are from a country or territory with the US dollar as a official currency, you will not need to worry about understanding prices and currency transferring. Also if you are from Bermuda, East Timor, Panama, or Bahamas, the official currencyies of the mentioned countries and territories have fixed exchange rates to the US Dollar. Meaning what price is said in the F.S.M. will be understood with your country's/territory's official currency. Example; $150 US Dollars will equal $150 Bermudian dollars, but you will still have to exchange currencies.
