There are some assumptions made in the construction of this argument. First of all, you can’t hide the risk from the economic community. There is no guarantee that when issuing Eurobonds, the interest rates will drop. This is happening for two main reasons.  Firstly, according to the proposition model, the bonds will still be issued at a national level, showing investors if the money is going to Spain, Italy or Germany, France. While these should in theory have the same interest rates will investors really buy Eurobonds where the money is destined for Greece if not getting much interest? Perception still matters to the markets; will Greece and Germany really suddenly be perceived in the same way.  Secondly, even if the European Union decides to borrow money as a whole, its image is not a good one. Everybody knows the major problems that the union is facing right now so it is possible that concerns about the stability of the Euro as a whole will mean Eurobonds drive interest rates up, not down. Greece was still downgraded after its first bailout from CCC to C by the Fitch Financial Service even if the money were backed up by the ECB, being backed by the whole zone did not change the local fundamentals.
