Since not all the EU states have joined the Euro, the ESCB could not be used as the monetary authority of the eurozone. For this reason the Eurosystem (which excludes all the NCBs which have not adopted the Euro) became the institution in charge of those tasks which in principle had to be managed by the ESCB. In accordance with the treaty establishing the European Community and the Statute of the European System of Central Banks and of the European Central Bank, the primary objective of the Eurosystem is to maintain price stability (in other words control inflation). Without prejudice to this objective, the Eurosystem shall support the general economic policies in the Community and act in accordance with the principles of an open market economy.
The basic tasks to be carried out by the Eurosystem are:
In addition, the Eurosystem contributes to the smooth conduct of policies pursued by the competent authorities relating to the prudential supervision of credit institutions and the stability of the financial system. The ECB has an advisory role vis-à-vis the Community and national authorities on matters which fall within its field of competence, particularly where Community or national legislation is concerned. Finally, in order to undertake the tasks of the ESCB, the ECB, assisted by the NCBs, has the task of collecting the necessary statistical information either from the competent national authorities or directly from economic agents.
The process of decision-making in the Eurosystem is centralised through the decision-making bodies of the ECB, namely the Governing Council and the Executive Board. As long as there are Member States which have not adopted the euro, a third decision-making body, the General Council, shall also exist. The NCBs of the Member States which do not participate in the euro area are members of the ESCB with a special status while they are allowed to conduct their respective national monetary policies, they do not take part in the decision-making with regard to the single monetary policy for the euro area and the implementation of such decisions.
The Governing Council comprises all the members of the Executive Board and the governors of the NCBs of the Member States without a derogation, i.e. those countries which have adopted the euro. The main responsibilities of the Governing Council are:
The Executive Board comprises the President, the Vice-President and four other members, all chosen from among persons of recognised standing and professional experience in monetary or banking matters. They are appointed by common accord of the governments of the Member States at the level of the Heads of State or Government, on a recommendation from the Council of Minsters after it has consulted the European Parliament and the Governing Council of the ECB (i.e. the Council of the European Monetary Institute (EMI) for the first appointments). The main responsibilities of the Executive Board are:
The General Council comprises the President and the Vice-President and the governors of the NCBs of all 27 Member States. The General Council performs the tasks which the ECB took over from the EMI and which, owing to the derogation of one or more Member States, still have to be performed in Stage Three of Economic and Monetary Union (EMU). The General Council also contributes to:
The Eurosystem is independent. When performing Eurosystem-related tasks, neither the ECB, nor an NCB, nor any member of their decision-making bodies may seek or take instructions from any external body. The Community institutions and bodies and the governments of the Member States may not seek to influence the members of the decision-making bodies of the ECB or of the NCBs in the performance of their tasks. The Statute of the ESCB makes provision for the following measures to ensure security of tenure for NCB governors and members of the Executive Board:
The ECB's capital amounts to €5 billion. The NCBs are the sole subscribers to and holders of the capital of the ECB. The subscription of capital is based on a key established on the basis of the EU Member States' respective shares in the GDP and population of the Community. It has, thus far, been paid up to an amount just over €4 billion. The euro area NCBs have paid up their respective subscriptions to the ECB's capital in full. The NCBs of the non-participating countries have paid up 5% of their respective subscriptions to the ECB's capital as a contribution to the operational costs of the ECB. As a result, the ECB was endowed with an initial capital of just under €4 billion. When Greece entered the third stage of EMU on 1 January 2001 the Bank of Greece paid up the remaining 95% of its subscription to the ECB's capital.
In addition, the NCBs of the Member States participating in the euro area have provided the ECB with foreign reserve assets of up to an amount equivalent to around €40 billion. The contributions of each NCB were fixed in proportion to its share in the ECB's subscribed capital, while in return each NCB was credited by the ECB with a claim in euro equivalent to its contribution. 15% of the contributions were made in gold, and the remaining 85% in US dollars and Japanese yen.
