BERLIN — German industrial output fell sharply in May, a third consecutive drop that suggests Europe’s biggest economy and engine of growth lost steam in the second quarter amid slowing business in China and tensions over Ukraine.

The 1.8 per cent drop compared with the previous month also reinforces concerns over the economy of the wider 18-country eurozone as other countries, such as France, are still too weak to pick up the slack.

Monday’s figure, published by the Federal Statistical Office, undercut economists’ expectations for no change. Production slipped 0.3 per cent in April, revised downward from the initial reading of 0.2 per cent growth.

The Economy Ministry pointed to a calendar effect from holidays in May and expected weakness in construction after very mild weather in the year’s first quarter but said “geopolitical causes” may also have contributed. Tensions with Moscow over the crisis in Ukraine have raised concerns that western powers, including Germany, might sanction business ties with Russia.

Overall, German industrial activity remains strong and companies have well-filled order books, but “the stimulus for a further acceleration is currently missing,” ING economist Carsten Brzeski said. He argued the data shows that “risk factors like slowing emerging market economies, including China, and geopolitical conflicts do have an impact on the German economy.”

Germany’s economy grew by a robust 0.8 per cent in the first quarter compared with the previous three-month period, helping push eurozone output up a feeble 0.2 per cent despite the French and Italian economy’s failure to pick up and declines in the Netherlands and elsewhere.

Mixed signals from recent data have fuelled expectations of much slower German second-quarter growth, likely depriving the eurozone of much-needed support.

UniCredit economist Martina von Terzi said there are strong risks that German growth will undershoot her forecast of 0.5 per cent in the second quarter. Retail sales and manufacturing activity have disappointed recently, though export data have yet to be released.
