Franc
The Swiss franc (ISO code: CHF or 756), which appreciated significantly against the new European currency from April to September 2000, remains one of the world's strongest currencies, worth today around five-sixths of a euro. The Swiss franc is used in Switzerland and in Liechtenstein. Liechtenstein retains the ability to mint its own currency, the Liechtenstein franc, which it does from time to time for commemorative or emergency purposes.
Sweden
Sweden maintains its own currency, the Swedish krona (SEK), a result of the Swedes having rejected the euro in a referendum. The Swedish Riksbank—founded in 1668 and thus the oldest central bank in the world—is currently focusing on price stability with an inflation target of 2%. According to the "Economic Survey of Sweden 2007" by the OECD, the average inflation in Sweden has been one of the lowest among European countries since the mid-1990s, largely because of deregulation and quick utilisation of globalisation.
