BERLIN (Reuters) -German business morale improved more than expected in October, following five consecutive months of decline, a survey showed on Wednesday, but economists still fear a recession. The Ifo institute said its business climate index stood at 86.9 versus the 85.9 reading forecast by analysts in a Reuters poll, following a slightly revised reading of 85.8 in September. "Germany's economy can see a silver lining ahead," Ifo president Clemens Fuest said.
