As the European Commission discusses jointly issuing euro-bonds by eurozone members, German Chancellor, Angela Merkel says she strongly opposes the idea. But some economists say the introduction of these so called \"stability bonds\" is the only way to end the debt crisis. Germany’s strong economy has held up relatively well despite the debt crisis swirling around Europe. But analysts said the first signs it was beginning to threaten Berlin came on Wednesday - when Germany had one of the worst bond sales since the launch of the euro. It still costs Germany significantly less to sell its debt than all its euro zone neighbours, but the Bundesbank was forced to buy large amounts of the bonds to ensure the auction didn’t fail. This, on a day where the European Commission discussed the introduction of eurobonds - an idea German Chancellor Angela Merkel once again rejected.
