Switzerland–European Union relations
The currency of Switzerland is the Swiss franc. Switzerland (with Liechtenstein) is in the unusual position of being surrounded by countries that use the euro. As a result, the euro is "de facto" accepted in many places, especially near borders and in tourist regions. Swiss Federal Railways accept euros, both at ticket counters and in automatic ticket machines. Also many public phones, vending machines or ticket machines accept euro coins. Many shops and smaller businesses that accept euros take notes only, and give change in Swiss francs, usually at a less favourable exchange rate than banks. Many bank cash machines issue euros at the traded exchange rate as well as Swiss francs.
Swiss franc
In March 2011, the franc climbed past the US$1.10 mark (CHF 0.91 per U.S. dollar). In June 2011, the franc climbed past US$1.20 (CHF 0.833 per U.S. dollar) as investors sought safety as the Greek sovereign debt crisis continued. Continuation of the same crisis in Europe and the debt crisis in the US propelled the Swiss franc past US$1.30 (CHF 0.769 per U.S. dollar) as of August 2011, prompting the Swiss National Bank to boost the franc's liquidity to try to counter its "massive overvaluation". "The Economist" argued that its Big Mac Index in July 2011 indicated an overvaluation of 98% over the dollar, and cited Swiss companies releasing profit warnings and threatening to move operations out of the country due to the strength of the franc. Demand for francs and franc-denominated assets was so strong that nominal short-term Swiss interest rates became negative.
