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
In 1907, the Swiss National Bank took over the issuance of banknotes from the cantons and various banks. It introduced denominations of 50, 100, 500 and 1000 francs. 20-franc notes were introduced in 1911, followed by 5-franc notes in 1913. In 1914, the Federal Treasury issued paper money in denominations of 5, 10 and 20 francs. These notes were issued in three different versions: French, German and Italian. The State Loan Bank also issued 25-franc notes that year. In 1952, the national bank ceased issuing 5-franc notes but introduced 10-franc notes in 1955. In 1996, 200-franc notes were introduced whilst the 500-franc note was discontinued.
