No quantum leap on eurozone integration after the German elections

It's constitutionally complicated, for example, to write down Greek debt, given that 75% of it is now owned by taxpayer-backed institutions in Germany and the rest of the euro zone. If those institutions take losses on what until now have been loan guarantees, that will in effect turn the euro zone into a transfer union for the first time, which the Constitutional Court has said is illegal. German politicians will continue to have one hand tied by the court in Karlsruhe for years to come.
