London: The euro rebounded against the dollar Tuesday after European Central Bank chief Mario Draghi struck an optimistic tone on the eurozone economy. The European Union is experiencing a newfound confidence that could unlock demand and investment, Draghi said, while insisting on"prudence"in any monetary adjustments. Speaking at a central bank forum in the Portuguese resort town of Sintra, Draghi said that for years uncertainty over whether the eurozone would seriously reform labour markets had acted as a brake on investments and confidence.
