If I, as a central banker, am allowed to present my assessment, I would argue that the Convention has done a very good job of incorporating the substance of the EMU chapter into the new Constitution, while also introducing clarifications, additions and updates in the current texts where necessary and appropriate.
What I do miss is that the Convention has not taken over our suggestion to incorporate somewhere in the text the notion of Eurosystem, which stands for the core concept of our central banking system, i.e. the ECB and the national central banks of the member states that have adopted the euro.
