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.
Switzerland–European Union relations
On 6 September 2011, the Swiss franc effectively became fixed against the euro: the Franc had always floated independently until its currency appreciation became unacceptable during the eurozone debt crisis. The Swiss National Bank set an CHF/EUR peg that involved a minimum exchange rate of 1.20 francs to the euro, with no upper bound in place. The Bank committed to maintaining this exchange rate to ensure stability. The peg was abandoned on 15 January 2015, when renewed upward pressure on the Swiss franc exceeded the Bank's level of tolerance.
