Is There A Limit To Draghi's Negative Interest Rate Madness?

``Millions of mortgages in Europe are based on Euribor. The vast majority of mortgage rates in Spain and Portugal are based on Euribor. A huge number in Italy are based on Euribor. The typical mortgage loan in many Eurozone countries is Euribor plus 1 percentage point. For those on 1-month Euribor, the interest banks collect is no longer 1%. Instead, banks collect 0.70%. Servicing fees eat into that profit. If Euribor fell below -1.0% banks would have to pay customers interest on their mortgages rather than collect interest!''
