Six years ago twelve member states of the European union changed their currencies to a new one: the EURO. Since then the new money has justified its existance, becoming a steady currency, with a good reputation. The problems that euro is facing are mostly consequence of speculations in the market of world currencies. Euro is trying to take over the leadership of the USD, competing with the Japanese yen and the Swiss franc. The strengthening of its force is a reflection of stability, but it reduces competitivity of exports from the euro-zone. Euro could probably reach the top and with the continous sliding of the dollar, this could happen quite soon.
