The Swiss franc is also the currency used for administrative and accounting purposes by most of the numerous international organisations that are headquartered in Switzerland.
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.
