Draghi worried about the power of the euro?

The head of the ECB, Mario Draghi, is worried about the strength of the single currency against the dollar and other major currencies. Since the beginning of the year, the euro has risen by 12% against the dollar.
Thus, Draghi expressed same fears, repeatedly given by the previous ECB chief, Jean-Claude Trichet, that the strong euro could seriously hurt growth prospects for the eurozone economy.
In addition, the strong European currency puts a pole in the wheel of inflation. And inflation is one of the main threats to the growth of the eurozone economy.
