In addition, there is a very strict rule prohibiting the monetary financing of the public sector that makes clear that monetary policy and fiscal policy should be two separate areas of policy. Furthermore, 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.
Moreover, the national central banks may continue to carry out other tasks and activities, provided that they are in line with the single monetary policy. The decision-making bodies of the Eurosystem are the Executive Board and the Governing Council of the ECB.
