It’s not just that the market isn’t deep enough. The current incarnation of EU bonds are not secured the same way typical sovereign bonds are. And they sort of can’t be without the member states ceding more sovereignty.

We’ll see if the EU member countries can approve a framework for bonds that are closer to a treasury in its guarantees, I’m skeptical but it could happen, but they don’t exist right now.

So the EU should issue more volume and establish a strategy to start rotating from US debt to EU debt. No one is calling for dumping $8T of treasuries on the market overnight; it's entirely reasonable to start issuing Euro debt and communicating the expectation to start selling down US treasuries to European entities that hold them.
