Replacing their currencies with the Euro would also benefit both Switzerland and Norway. Over the past ten years the Euro has gained in strength and credibility, and is now clearly the world’s second currency after the dollar. The high volatility of sterling shows the danger of trying to maintain your own currency as a national virility symbol, while Iceland shows the risk small countries face when financial trouble strikes. For Switzerland, switching to the Euro would allow it to capitalize on its banking expertise by becoming a true rival to London as Europe’s financial center. For Norway, the Euro would help the country avoid “Dutch disease” – where a strong oil and gas industry pushes up the currency to the point where other businesses are severely hurt.
