The industrial output in the 17-nation economy rose more strongly than expected in February, boosted by a marked gain in energy production, suggesting that the currency bloc is recovering gradually from the severe debt crisis. Region's output rose 0.4% in February compared with January, when it dropped 0.6%, beating analysts' expectations of a 0.3% increase, the official data showed Friday. Despite the improvement, recent economic data for the currency-bloc paint a bleak picture, and risks of another quarterly contraction in the gross domestic product are still high.
