If even Greece now gets away with issuing negative yielding debts, then this is a signal that somethign very serious is going terribly wrong.
Mind you, by definition, there can not be something like negative interests". By definition and meaning, interests always must and can only be positive, if they are not, then they are no interests at all, but fees, taxes, whatever you call it - but no interests.
