On May 18, 2026, the Directorate-General for Financial Stability, Financial Services and Capital Markets Union (DG FISMA) published a technical paper providing a stocktake of existing sectoral data dictionaries in European Union financial services. The document complements a 2025 technical paper on a common data dictionary that outlined the purpose and intended content of such a dictionary to establish shared understanding among relevant authorities. This second technical paper presents a factual summary of existing sectoral data dictionaries in EU financial services, based on a survey conducted by DG FISMA staff among relevant EU authorities that are members of the Supervisory Reporting Roundtable. The stocktake aims to understand the purpose, content and functionalities of sectoral data dictionaries that have either been developed or are under development across the financial services sector. The Supervisory Reporting Roundtable is an informal coordination body established by DG FISMA to guide the preparation and implementation of the strategy on supervisory data. The roundtable comprises representatives responsible for reporting and data from relevant EU authorities, including the European Supervisory Authorities, European Systemic Risk Board, Single Resolution Board, European Central Bank and Anti-money Laundering Authority. The technical paper is available in English as a PDF document and provides financial services authorities, supervisory bodies and market participants with a comprehensive overview of current data dictionary initiatives across EU financial services sectors. The stocktake supports ongoing efforts to harmonise supervisory data standards and improve data quality across the EU financial system.
