The current crisis has hit almost every financial institution, as there was a tight interdependence and close network between banks. Three issues arise from the meeting of state aid control and the crisis: the question of policy, the core content of tools used, and the economic consequences.

At the same time, the policy applied all along the crisis was characterized by a consistency in principles and flexibility on means.

Can we guess where is state aid control going? And furthermore, what to do to of it after the crisis?
