Greece's new (unelected) Prime Minister, Lucas Papademos, was Vice President of the European Central Bank from 2002 until 2010.

The European Central Bank is the institution of the European Union (EU) that administers the monetary policy of the 17 EU Eurozone member states. It is thus one of the world's most important central banks. The bank was established by the Treaty of Amsterdam in 1998, and is headquartered in Frankfurt, Germany. The current President of the ECB is Mario Draghi, former governor of the Bank of Italy.

The primary objective of the European Central Bank is to maintain price stability within the Eurozone, which is the same as keeping inflation low. The Governing Council defined price stability as inflation of around 2%. (Harmonised Index of Consumer Prices) Unlike, for example, the United States Federal Reserve Bank, the ECB has only one primary objective with other objectives subordinate to it.

The key tasks of the ECB are to define and implement the monetary policy for the Eurozone, to conduct foreign exchange operations, to take care of the foreign reserves of the European System of Central Banks and promote smooth operation of the financial market infrastructure under the Target payments system and being currently developed technical platform for settlement of securities in Europe (TARGET2 Securities). Furthermore, it has the exclusive right to authorise the issuance of euro banknotes. Member states can issue euro coins but the amount must be authorised by the ECB beforehand (upon the introduction of the euro, the ECB also had exclusive right to issue coins).

On 9 May 2010, the 27 member states of the European Union agreed to incorporate the European Financial Stability Facility. The EFSF’s mandate is to safeguard financial stability in Europe by providing financial assistance to Eurozone Member States.

The bank must also co-operate within the EU and internationally with third bodies and entities. Finally it contributes to maintaining a stable financial system and monitoring the banking sector. The latter can be seen, for example, in the bank's intervention during the 2007 credit crisis when it loaned billions of euros to banks to stabilise the financial system.

Although the ECB is governed by European law directly and thus not by corporate law applying to private law companies, its set-up resembles that of a corporation in the sense that the ECB has shareholders and stock capital. Its capital is five billion euro which is held by the national central banks of the member states as shareholders. The initial capital allocation key was determined in 1998 on the basis of the states' population and GDP, but the key is adjustable. Shares in the ECB are not transferable and cannot be used as collateral.

Throughout 2011 various member states of the European Union showed themselves to be increasingly unable to meet financial commitments. At its heart, the crisis of the European currency unit or ECU is similar to almost any other financial crisis, including the crisis of 2008. Key concepts to understanding the crisis include collateral, assets, and liabilities.

The bank is based in Frankfurt, the largest financial centre in the Eurozone. Its location in the city is fixed by the Amsterdam Treaty along with other major institutions. In the city, the bank currently occupies Frankfurt's Eurotower until its purpose-built headquarters are built.
