On 2 July 2026, ESMA published its Final Report on the simplification of the reporting of financial transactions. According to the Authority, this report lays the foundations for moving towards a ‘report once’ approach, underpinned by a new integrated and unified reporting framework. To this end, it presents a detailed analysis, on the basis of which it sets out a series of recommendations addressed to the co-legislators, namely the European Parliament and the Council. The aim is to reduce costs whilst improving the quality and usability of data for supervisors; consequently, this initiative forms part of the European Commission’s (EC) current policy on simplification and burden reduction.
ESMA describes this approach as a combination of intermediate measures aimed at reducing administrative burdens in the short term, implemented progressively, alongside a longer-term structural reform, which seeks to apply the report once approach to the data submitted to supervisors under the MiFIR¹, EMIR² and SFTR³ regulations. This report is accompanied by two cost-benefit analyses: one focusing on the impact on market participants, carried out by the consultancy firm Deloitte, and the other on the impact on national and European Union (EU) supervisory authorities, conducted by ESMA.
ESMA has based its work on four fundamental principles: preserving the value of the information reported, reducing existing overlaps and duplication, promoting international harmonisation, and ensuring an appropriate balance between the costs and benefits of any reform.
With regard to costs, the responses received from the industry and the analysis carried out by the consultancy firm identify three main factors. Firstly, regulatory complexity arising from frequent regulatory changes which are, at times, not synchronised across the various disclosure or reporting regimes. Secondly, the duplication of obligations and the fragmentation of communication channels. Thirdly, the requirement for both counterparties to report the same transaction (dual-sided reporting), together with the corresponding data reconciliation requirements.
In June 2025, with the aim of gathering the industry’s views, ESMA published a call for evidence⁴ on a possible comprehensive simplification of financial transaction reporting obligations. The document sets out two main approaches:
The first involved, as first option, distinguishing between the regime applicable to exchange-traded derivatives (ETDs) and that applicable to over-the-counter (OTC) derivatives. As a second option, it proposed distinguishing between information relating to transactions (MiFIR) and post-trade information (EMIR).
The second, as a long-term option, was based on the report once principle, which would mean reporting information only once. Two alternatives were also considered in this approach: applying it to the reporting regimes under MiFIR, EMIR and SFTR, or extending it to other regimes.
Finally, in this report, ESMA proposes a two-step structural approach: a series of standalone intermediate measures and a long-term scenario applying the report once principle (referred to as Option 2a), with the integration of reporting within MiFIR, EMIR and SFTR.
ESMA estimates that the implementation of the new integrated framework could be completed in the second half of 2031. In the meantime, the intermediate measures could be adopted progressively, depending on their complexity and the regulatory changes required.

⁴ During this period, ESMA has also organised various workshops, a Data Day and a public hearing.
