The modern Swiss franc was introduced in 1850, two years after the formation of Switzerland as a federal state. The federal law establishing the new currency was passed on 7 May 1850. For practical reasons, the Swiss franc was initially created as having parity with the French franc of the day (introduced 1795), with 1 franc equivalent to 5 grams of silver at 90% purity. The official exchange rate with the cantonal concordate currency was seven Batzen to one franc.
