I wonder if it is possible to design a currency union with just a small amount of decoupling between the individual national bonds and the unified currency? e.g. all members of the union are required to make certain transactions in euro, but issue national debt in their own currency which floats in exchange vs the euro? I think this scheme has problems, but it seems like with the right decoupling points somewhere in the system, you might be able to operate the euro more robustly.
