History of Switzerland
Switzerland's most important exports during the war were precision machine tools, watches, jewel bearings (used in bombsights), electricity, and dairy products. During World War Two, the Swiss franc was the only remaining major freely convertible currency in the world, and both the Allies and the Germans sold large amounts of gold to the Swiss National Bank. Between 1940 and 1945, the German Reichsbank sold 1.3 billion francs worth of gold to Swiss Banks in exchange for Swiss francs and other foreign currency.
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.
