Additional supervisory data quality checks
The ECB’s Banking Supervision Data Division, in cooperation with national competent authorities (NCAs) within the Single Supervisory Mechanism (SSM), has published a set of extra data quality checks in addition to those already included in the European Banking Authority’ssupervisory reporting frameworks.
These extra checks are aimed at enhancing the quality of supervisory reporting data in accordance with Article 4(1) of Decision ECB/2023/18 of 17 August 2023. The ECB applies these checks in conjunction with other controls as part of the quality assessment of supervisory reporting data. The list below is updated as new checks are deemed necessary and defined.
List of additional checks (updated on 30 January 2026)The next update of the list will be published before the end of October 2026 and will have a first reference date of 31 December 2026.
The ECB strongly encourages significant institutions (SIs) within the SSM to implement the extra checks in their own reporting systems prior to the submission of data to NCAs. SIs are also encouraged to ensure compliance with the checks before reporting to the NCAs under the supervisory reporting frameworks.
List of additional checks – preview version in DPM-XL format (updated on 30 January 2026)In parallel with the regular publication, the list of additional checks is also made available as a “preview” release in EBA DPM-XL format, to align the specifications to the format used for the EBA validation rules publishedhere. The release in DPM-XL format is to be considered experimental and is only intended to collect feedback from the industry, in view of a future adoption of this format. At the current stage, it should not be used as a reference for implementation.
