The Committees assist the work of the decision-making bodies of the ECB, which can request them to provide any information in their fields of expertise in order to facilitate the decision-making process and the implementation of decisions.
Participation is usually restricted to experts of the Eurosystem central banks. However, the national central banks (NCBs) of the EU Member States which have not yet adopted the euro take part in the meetings of a Committee whenever appropriate. Moreover, representatives of other competent bodies may also be invited, such as national supervisory authorities in the case of the Banking Supervisory Committee.
