(ANSA) - BELGRADE, AUG 6 - According to the German federal statistics office Destatis, industrial orders unexpectedly increased in Germany by 3.1% (seasonally adjusted) in June. Although experts had predicted an increase of only half a percentage point, this is the second consecutive increase since May. Economists worry that the economy will be impacted by the low Rhine water levels. The main inland waterway in Europe recently experienced record low water levels, which occasionally made it impossible for ships to sail. This situation puts the supply chain at risk of disruption, which could have detrimental effects on production. (ANSA).
