The Swiss franc is also the currency used for administrative and accounting purposes by most of the numerous international organisations that are headquartered in Switzerland.
Economy of Switzerland
Swiss neutrality and national sovereignty, long recognized by foreign nations, have fostered a stable environment in which the banking sector was able to develop and thrive. Switzerland has maintained neutrality through both World Wars, is not a member of the European Union, and was not even a member of the United Nations until 2002. Currently an estimated 28 percent of all funds held outside the country of origin (sometimes called "offshore" funds) are kept in Switzerland. In 2009 Swiss banks managed 5.4 trillion Swiss Francs.
