Economy of Liechtenstein
The economy of Liechtenstein is based roughly equally on services (especially financial services) and industry, with a small but significant agricultural sector. The country participates in a customs union with Switzerland and uses the Swiss franc as its national currency. It imports more than 85% of its energy requirements. Liechtenstein has been a member of the European Free Trade Association (EFTA) since 1991 (previously its interests had been represented by Switzerland). It also has been a member of the European Economic Area (EEA) since May 1995 and participates in the Schengen Agreement for passport-free intra-European travel.
Swiss franc
The franc fell 8.8% against the euro, 9.5% against the dollar, and at least 8.2% against all 16 of the most active currencies on the day of the announcement. It was the largest plunge of the franc ever against the euro. The SNB had previously set an exchange rate target in 1978 against the Deutsche mark and maintained it, although at the cost of high inflation. Until mid-January 2015, the franc continued to trade below the target level set by the SNB, though the ceiling was broken at least once on 5 April 2012, albeit briefly.
