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.
Liechtenstein
Liechtenstein participates in a customs union with Switzerland and employs the Swiss franc as the national currency. The country imports about 85% of its energy. Liechtenstein has been a member of the European Economic Area (an organization serving as a bridge between the European Free Trade Association (EFTA) and the European Union) since May 1995.
