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.
Currency intervention
As investors flocked to the franc during the financial crisis, they dramatically pushed up its value. An expensive franc may have large adverse effects on the Swiss economy; the Swiss economy is heavily reliant on selling things abroad. Exports of goods and services are worth over 70% of Swiss GDP. To maintain price stability and lower the franc's value, the SNB created new francs and used them to buy euros. Increasing the supply of francs relative to euros on foreign-exchange markets caused the franc's value to fall (ensuring the euro was worth 1.2 francs). This policy resulted in the SNB amassing roughly $480 billion-worth of foreign currency, a sum equal to about 70% of Swiss GDP.
