AlQa'dah 25, 1433, Oct 11, 2012, SPA -- Germany's leading economic institutes slashed their growth forecasts for Europe's biggest economy Thursday and warned that the European Central Bank's new bond-buying programme could fuel inflationary pressures, according to dpa. In their twice yearly report, the five institutes said they expect the German economy to expand by 0.8 per cent this year and by 1.0 per cent in 2013. This compared with the institutes' forecasts unveiled earlier this year when they predicted the economy would grow by 0.9 per cent in 2012 and 2 per cent in 2013. "The eurozone debt crisis has Germany in its grip," the institutes said.
