The ISO 4217 currency code for Swiss Franc.
ISO 4217 code for the Swiss franc. Although the first Swiss franc was used briefly at the end of the 18th century, the modern franc was introduced in 1850, replacing almost two dozen local currencies. Switzerland was a member of the Latin Monetary Union until its demise in 1927 and later belonged to the Bretton Woods System. Until 2000, at least 40% of the franc was required to be backed by gold. The Swiss franc is known for having almost no inflation and as such is considered a very safe currency for investment.
