Supervisory disclosure

Supervisory disclosure enables national supervisors and other interested parties to compare different approaches and, ultimately, promotes convergence of supervisory practices in the EU.

The ECB, as the competent authority for the Single Supervisory Mechanism, regularly publishes information on:

Rules and guidance

Supervisory disclosure provides information on legal and regulatory texts, including:

  • national laws and regulations adopted by each EU Member State to implement the provisions of CRD IV and CRR
  • administrative rules, e.g. instructing supervised banks on how to comply with legislative and regulatory requirements
  • general guidance, e.g. explicit disclosure requirements under CRD IV, or any other information that supervisory authorities publish to increase understanding of the new capital adequacy framework

Rules and guidance

Options and national discretions

The ECB has undertaken work to harmonise the different supervisory options and discretions (O&Ds) existing in European legislation (CRR, CRD IV and delegated acts). Following a public consultation, it released a final ECB Regulation as well as a Guide on O&Ds.

Supervisory Review and Evaluation Process (SREP)

The ECB has developed a common methodology for the ongoing assessment of banks’ risks, their governance arrangements and their capital and liquidity situation for performing the Supervisory Review and Evaluation Process (SREP). It publishes details on the:

  • scope of application of the SREP (including proportionality)
  • assessment of SREP elements
  • review and evaluation of ICAAP and ILAAP
  • overall assessment and supervisory measures


Aggregate statistical data

The ECB publishes aggregate statistical data on the European banking sector, including data on credit risk, operational risk, market risk, waivers and supervisory actions and measures. The reference date for the data is 31 December of the preceding year.
