All in all, this crisis has evidently demonstrated that the banking sectors of the euro area and the New Member States are deeply integrated, has greatly reduced the chances of credit booms in the forthcoming years and may exert an extra disciplining power in countries prone to fiscal misbehaviour in the future.
For these reasons, I think it may act as a catalyst for the euro accession process. Importantly, it should be let to act as a catalyst, that is, it should not be used as an excuse to make the entry criteria, or their interpretation, more stringent.
