Regulatory reporting automation for banks

A regulatory reporting system needs to identify the reporting institution, consolidation scope and reference period before calculating figures. A bank may need different data selections for prudential, statistical and resolution reporting. The EBA reporting frameworks separate reporting modules and their applicable reference dates, so the newest available package is not automatically correct for every submission.

Automation should preserve the connection between a requirement and the data selected to satisfy that requirement. Report owners need an exception queue for missing source records and unresolved reconciliation differences. A technically accepted file can still contain figures based on an incorrect business interpretation.

A data point model defines reporting concepts and the dimensions needed to interpret them. The DPM Alliance brings the ECB, EBA and EIOPA together around this shared modeling methodology. A common definition helps institutions distinguish the reported amount from attributes such as reporting entity, period and currency.

XBRL taxonomies connect reporting concepts with a machine-readable exchange structure and associated rules. An xBRL-CSV report combines CSV data with metadata describing how those data represent reported facts. Procurement teams should check the exact taxonomy, filing rules and delivery channel required for each relevant report.

Data lineage records how a reported figure connects to source records and subsequent transformations. The Basel Committee review of risk data aggregation identifies end-to-end traceability as a continuing challenge across fragmented banking systems. Joining datasets without preserving their identifiers can make a discrepancy harder to investigate later.

A useful reporting test starts with a corrected source transaction and follows the resulting change through the calculation. The institution should be able to compare the revised output with the previous submission and explain the difference. COREP and FINREP returns can use different reporting concepts while drawing on overlapping bank records. Reconciliation with the relevant accounting or risk records helps reviewers identify unexplained gaps before approval.

Project Ellipse explored machine-executable reporting through a common data model before combining regulatory information with wider analytical sources. The prototype illustrates how explicit logical instructions can make report production easier to inspect. A project demonstration establishes an experimental approach, while each authority still determines the requirements applicable to an institution.

The BIS Innovation Hub provides the institutional context for this work on supervisory technology. For bank implementation teams, the practical question concerns whether a reporting instruction can be reproduced from a defined data snapshot. That requires versioned definitions and a recorded decision when the interpretation of a requirement changes.

Project AISE is an ongoing proof of concept examining supervisory AI with synthetic data and retail payments use cases. The experiment compares machine-readable reporting, knowledge graphs, deterministic analytics and constrained model-generated synthesis. These tests investigate analytical architectures without establishing a production reporting service for financial institutions.

For a bank reporting workflow, AI may help an analyst locate a definition or investigate an exception. The supporting source and the relevant version should remain available beside the suggested explanation. Approved calculation logic and the responsible reporting team must determine the final figures and submission decision.

The ECB implementation milestones for IReF distinguish future integrated statistical reporting from existing reporting obligations. The announced timetable provides for a pilot starting in the second quarter of 2030 and first official reporting in the second quarter of 2031. These dates remain subject to adoption of the IReF Regulation following the planned consultation.

Institutions can use that preparation period to examine reusable definitions and the evidence behind existing reports. Reporting software should keep current obligations separate from changes that remain in preparation. A migration plan also needs controlled comparisons when old and new reporting arrangements run alongside one another.

Acceptance testing should include incomplete data, a changed taxonomy and a corrected record from an earlier reporting period. Reviewers need to see which checks failed and how each correction affected the final figures. The test should also confirm that a submission acknowledgement is retained with the report version actually sent.

A buyer can ask the supplier to repeat the same calculation from the same approved data snapshot. A second useful test replaces one reporting rule and checks whether unaffected figures remain unchanged. Clear ownership of source data, reporting logic and final approval makes these results easier to assess.
