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.
Economy of Sweden
Sweden rejected the Euro in a referendum in 2003, and Sweden maintains its own currency, the Swedish krona (SEK). The Swedish Riksbank—founded in 1668 and thus making it the oldest central bank in the world—is currently focusing on price stability with its inflation target of 2%. According to "Economic Survey of Sweden 2007" by 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 utilization of globalization.
