The future
The EU Constitution proposes a more formal role for the ECOFIN ministers from Eurozone countries. According to a special protocol on the Euro-Group, an informal Euro-club will be established with a president elected for 2½ years and unified representation in international financial institutions and conferences.
In an EU of 25 countries, less than half will be Euroland-members, although all the applicant countries are committed in their accession treaties to join eventually.
