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.
Reserve currency
The Swiss franc, despite gaining ground among the world's foreign-currency reserves and being often used in denominating foreign loans, cannot be considered as a world reserve currency, since the share of all foreign exchange reserves held in Swiss francs has historically been well below 0.5%. The daily trading market turnover of the franc, however, ranked fifth, or about 3.4%, among all currencies in a 2007 survey by the Bank for International Settlements.
