The ECB will supervise the largest banks, assisted by the national supervisory authorities, which in turn will remain responsible for supervising the other banks in accordance with guidelines set by the ECB.
Building on the technical experience of the national authorities, the single supervisory mechanism will be charged with upholding a supranational vision drawing on the best practices in supervision, analysis and assessment of banking risks, enabling easier comparison between the intermediaries and systems of the various countries, and facilitating the control and attenuation of systemic risks.
