Franc
The Swiss franc (ISO code: CHF or 756), which appreciated significantly against the new European currency from April to September 2000, remains one of the world's strongest currencies, worth today around five-sixths of a euro. The Swiss franc is used in Switzerland and in Liechtenstein. Liechtenstein retains the ability to mint its own currency, the Liechtenstein franc, which it does from time to time for commemorative or emergency purposes.
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.
