The succesful conclusion of the Lisbon Treaty overlapped with the beginning of the financial crisis, which had a profound, political, economic, and social impact on the EU. The problem was the weakness of control of the EU on national budgetary policy, meaning it was unable to exert much-needed control over national economic policy. The problem for the EU started with Greece not being able to repay its debt, -> problems for the euro. Together with the worldwide banking crisis, other countries, like Portugal and Ireland started to require large amounts of funds provided by other MS. The economic and financial crisis has had profound effects on the EU including its constitutional structure. Some political responses expressed the desire to provide assistance to allying States; others the desire of increased oversight of national economic policy.
