Which currency is the only legal tender in Switzerland and Liechtenstein?

The Swiss franc is the only legal tender in both Switzerland and Liechtenstein.

Switzerland and Liechtenstein have shared a customs and currency relationship since the late nineteenth century. Liechtenstein adopted the Swiss franc in 1924 after ending its earlier monetary links with Austria. The arrangement remains in force, and the Swiss franc is the official currency in both countries.

The Swiss National Bank issues Swiss banknotes, while Swiss coins circulate in both states. Liechtenstein also produces commemorative coins denominated in Swiss francs, but it does not issue a separate national currency for everyday legal tender. The Swiss franc’s ISO code is CHF.

Euros may be accepted by some businesses in tourist areas, but they are not the official legal tender of either country. This distinction matters because currency acceptance by a merchant is not the same as a country’s legally established monetary unit.
