    Complaint about a financial market participant other than a trade repository or a credit rating agency

    If you wish to complain about a financial market participant (e.g. a bank, investment firm, etc.), please note that generally ESMA does not have power to investigate or take action against a financial market participant other than a credit rating agency or a trade repository. However, such complaints can be made to other bodies including the relevant national authorities. Further information on this and other possible options available to you can be found in the Investor Corner .

    In certain cases, ESMA can investigate and take action in relation to a complaint about a National Competent Authority which is responsible for the supervision of financial market participants such as banks, investment firms, etc. Please see below for further information.

    Complaint about a national competent authority

    ESMA has power under Article 17 of the ESMA Regulation (EU Regulation No 1095/2010) to investigate and take further action concerning the failure of National Competent Authorities to comply with their obligations under the legislation referred to in Article 1(2) of the ESMA Regulation.
