(ANSA) - BELGRADE, 13 AUG - The ZEW Indicator of Economic Sentiment for Germany decreased sharply in August, reaching now a minus 44.1 point level, down by 19.6 points compared to the previous month, the ZEW - Leibniz Centre for European Economic Research said in a statement today. The indicator's long-term average is 21.6 points, with "the ZEW Indicator of Economic at its lowest level since December 2011," the Centre noted. The ZEW index measures the investors expectations of the current state and future economic development in Germany. "The ZEW Indicator of Economic Sentiment points to a significant deterioration in the outlook for the German economy," said ZEW President Achim Wambach. "The most recent escalation in the trade dispute between the US and China, the risk of competitive devaluations, and the increased likelihood of a no-deal Brexit place additional pressure on the already weak economic growth," Wambach added. "This will most likely put a further strain on the development of German exports and industrial production," Wambach anticipated. (ANSA).
