Swiss franc
The Swiss franc is the currency and legal tender of Switzerland and Liechtenstein and also legal tender in the Italian exclave of Campione d'Italia. Although not formally legal tender in the German exclave of Büsingen am Hochrhein (the sole legal currency is the euro), it is in wide daily use there; with many prices quoted in Swiss francs. The Swiss franc is the only version of the franc still issued in Europe.
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.
