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.
Currency intervention
The Economist asserts that the SNB dropped the cap for the following reasons: first, rising criticisms among Swiss citizens regarding the large build-up of foreign reserves. Fears of runaway inflation underlie these criticisms, despite inflation of the franc being too low, according to the SNB. Second, in response to the European Central Bank's decision to initiate a quantitative easing program to combat euro deflation. The consequent devaluation of the euro would require the SNB to further devalue the franc had they decided to maintain the fixed exchange rate. Third, due to recent euro depreciation in 2014, the franc lost roughly 12% of its value against the USD and 10% against the rupee (exported goods and services to the U.S. and India account for roughly 20% Swiss exports).
