Deep financial crisis which started in 2007 proved to be extremely contagious affecting the financial and banking EU system. Achieving an integrated banking market is the main component of the European policy in the financial-banking services area. The latest developments underlined that the difficulties faced by the banks can negatively impact on the entire financial stability of the member states. That’s why, the European Central Bank will be entitled to supervise any bank of the euro area, especially the ones that benefit of public support. Reforming the financial and banking system must be shaped in the frame of insuring some durable national finances, of an urgent recapitalizing of the banks that need that and of elaborating some common fiscal and financial and banking regulations effective in the eurozone.
