Austrian real estate mogul Rene Benko and his Signa Group, one of Europe's biggest real estate groups, may be in lethal troubles. This is no surprise given the new economic environment of high interest rates, restrictive lending and stagnating real estate prices. Over the past two decades, Signa Group has grown explosively. Now the German rating agency Creditreform has suspended the rating for Signa Group, which is a new disaster news. Insolvency is no longer ruled out.
