(ANSA) - BELGRADE, MARCH 25 - The sentiment among German managers has become extraordinarily dire, with the ifo Business Climate Index collapsing from 96.0 points in February to 86.1 points in March, the Ifo Institute said in a statement today. This is the steepest fall ever recorded since German reunification and the lowest value since July 2009, Ifo noted. "Companies' expectations in particular have darkened as never before," with "assessments of the current situation have also worsened considerably. The German economy is in shock," Ifo concluded.
