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
Although 22 cantons and half-cantons issued coins between 1803 and 1850, less than 15% of the money in circulation in Switzerland in 1850 was locally produced, with the rest being foreign, mainly brought back by mercenaries. In addition, some private banks also started issuing the first banknotes, so that in total, at least 8000 different coins and notes were in circulation at that time, making the monetary system extremely complicated.
