More signs of continued economic strength in Europe came on Wednesday, as industrial output numbers for May rose by more than expected, boosted by a jump in capital goods and consumer durables production.

Industrial production in the euro zone rose by 1.3% in May, versus a Reuters poll of 42 economists which expected a 1.1% increase.

The rise provides some ammunition for European Central Bank policy makers who are pushing for a September announcement about stimulus tapering. However, the increase was largely driven by Germany, and policy makers will likely look for evidence of more broad-based strength.
