The distinction between the euro area and the EU means that it is more difficult to fully tailor accountability to euro area tasks. In particular, the European Parliament does not sit in euro area composition when discussing euro area matters, even though it would be common sense for it to do so.
Accountability and sovereignty also need to be proportionate in areas that are not exclusively dealt with at EU or euro area level but are areas of shared competence. This holds true for the ESM and for fiscal policies, where the situation is somewhat more complex and blurred.
