There are two benefits to this. For Americans and others with dollars, there is no need for currency exchange or to worry about exchange rates. The Panamanian Constitution forbids the government from printing paper currency. Thus a second benefit is that, unlike most nations, the Panamanian government cannot just turn on the printing presses when it wants more money. Panamanians have to earn their currency from the world market through hard work and intelligence. There is none of the wild inflation that has plagued so many Latin American nations.
