How Do the Recent MiFIR Review Proposals Affect the Scope of RTS 22 Reporting?

Concept

The regulatory framework governing financial markets is in a perpetual state of refinement, a direct reflection of the markets’ own evolution. The proposed amendments to the MiFIR (Markets in Financial Instruments Regulation) framework, specifically concerning Regulatory Technical Standard 22 (RTS 22), represent a critical juncture in this process. For financial institutions, understanding these changes extends beyond a simple compliance checklist; it necessitates a deep appreciation of the systemic goals driving the European Securities and Markets Authority (ESMA).

The core objective is the enhancement of market transparency and data integrity, achieved through a recalibration of transaction reporting obligations. This is not a ground-up reinvention but a highly targeted set of modifications designed to resolve ambiguities, standardize data across parallel regulatory streams, and adapt the reporting structure to accommodate new financial instruments and market structures, such as those involving distributed ledger technology (DLT).

At its heart, the MiFIR review seeks to elevate the utility of the reported data. Regulators have identified inconsistencies and data gaps in the current regime that impede their ability to effectively monitor for market abuse and systemic risk. The proposals are engineered to produce a dataset that is more coherent, consistent, and complete.

This is achieved by focusing on three primary vectors of change ▴ harmonization with other major reporting regimes like the European Market Infrastructure Regulation (EMIR) and the Securities Financing Transactions Regulation (SFTR), a more precise definition of the scope of reportable transactions, and the introduction of more granular data fields that provide a clearer picture of the entire transaction lifecycle. For a systems architect within a financial institution, these proposals are a mandate to re-evaluate and re-engineer the data capture, processing, and reporting pipelines to align with a more rigorous and logically consistent standard.

The Rationale for Refinement

The impetus behind the RTS 22 review is multifaceted, stemming from years of practical application and analysis of the data collected since MiFID II’s implementation in 2018. ESMA’s objective is to sharpen the tools of regulatory oversight. The existing framework, while comprehensive, has revealed certain structural weaknesses. For instance, inconsistencies in how derivatives are reported under MiFIR versus EMIR create operational burdens for firms and analytical challenges for regulators.

The proposals aim to dismantle these data silos, fostering a more unified reporting logic across regulations. This alignment is a cornerstone of the review, promising to reduce the complexity of reporting for firms that must comply with multiple regimes. A unified data standard means that a single, well-structured internal data model can serve multiple reporting requirements, leading to greater efficiency and a lower probability of error.

The core driver of the RTS 22 update is the pursuit of higher-fidelity market data through regulatory harmonization and targeted scope adjustments.

Furthermore, the financial landscape has not remained static. The emergence of crypto-assets and the use of DLT for issuing and trading financial instruments present a new frontier for regulators. The MiFIR review proactively addresses this by proposing the inclusion of specific identifiers for DLT-based instruments, ensuring that the reporting framework remains relevant in a tokenized future.

This forward-looking approach demonstrates a commitment to creating a durable regulatory architecture that can adapt to technological innovation. The review also tackles more granular, persistent issues, such as the precise identification of the parties to a trade and the linking of aggregated orders to their subsequent allocations, which are critical for reconstructing complex trading activities and ensuring accountability.

Strategy

Adapting to the proposed changes in RTS 22 requires a strategic approach that transcends mere technical implementation. Financial institutions must view this as an opportunity to enhance their data governance and operational architecture. The primary strategic challenge lies in managing the divergence between the EU and UK reporting regimes while simultaneously capitalizing on the efficiencies offered by harmonization with EMIR and SFTR.

A successful strategy will involve a comprehensive gap analysis of current reporting systems against the proposed requirements, a detailed plan for sourcing new data points, and a robust testing protocol to ensure accuracy before the implementation deadline. The strategic focus should be on building a flexible and scalable reporting infrastructure that can accommodate not only the current set of changes but also future regulatory evolutions.

Navigating the Shifting Scope of Reporting

The most significant strategic consideration for many firms will be the recalibration of the reporting scope. While the foundational “Traded on a Trading Venue” (TOTV) concept persists, its application is being refined. The narrowing of the scope for certain Over-the-Counter (OTC) derivatives will be a welcome change for some firms, reducing their reporting burden.

Conversely, the inclusion of a new class of OTC interest rate and credit derivatives that are subject to the clearing obligation will bring new transactions into the reporting net for others. This requires firms to conduct a thorough analysis of their product offerings and trading activities to determine how their overall reporting volume and complexity will be affected.

Firms must develop a clear methodology for identifying which transactions fall under the revised scope. This involves ▴

• Product Taxonomy Review ▴ A complete mapping of the firm’s financial instrument inventory against the revised TOTV and uTOTV definitions, with particular attention to the new class of in-scope OTC derivatives.
• Execution Venue Analysis ▴ Re-evaluating how transactions executed on non-EEA venues are treated, especially concerning the new requirements for Trading Venue Transaction Identification Codes (TVTICs).
• DLT Instrument Identification ▴ Establishing a process to identify and flag financial instruments that are natively issued or tokenized on a distributed ledger, as these will require a new DLT identifier in the transaction report.

Harmonization as a Strategic Advantage

The alignment of RTS 22 with EMIR and SFTR presents a significant opportunity for strategic efficiency. For years, firms have grappled with the operational headaches of reporting similar or identical data points to different regulators using slightly different formats or definitions. The harmonization effort aims to alleviate this burden. By adopting consistent data standards, such as the ISO 20022 standard, and aligning field definitions for elements like buyer/seller identification and price, the review paves the way for a more integrated and streamlined reporting process.

A forward-thinking institution will leverage this to re-architect its internal data models. Instead of maintaining separate data streams for MiFIR and EMIR reporting, firms can build a unified data repository that serves as a single source of truth for all transaction reporting obligations. This not only reduces operational costs but also enhances data quality and consistency across the board.

Strategic alignment with the EMIR and SFTR frameworks is a core component of the RTS 22 proposals, offering firms a path to greater reporting efficiency.

The table below illustrates the strategic shift from a siloed to a harmonized reporting approach:

Execution

The execution phase of adapting to the RTS 22 review demands a granular focus on data fields, system logic, and operational workflows. The transition from the current to the proposed reporting standard is a complex undertaking that requires precise project management and deep technical expertise. The core of the execution challenge lies in the field-level changes ▴ the introduction of new data elements, the modification of existing ones, and the removal of those deemed redundant.

Firms must meticulously map these changes to their internal systems, identify data gaps, and build the necessary logic to populate the reports correctly. This process must be completed well in advance of the 2026 go-live target to allow for comprehensive testing and validation.

Implementing New and Amended Data Fields

A significant portion of the implementation effort will revolve around the new data fields being introduced to enhance regulatory oversight. These fields provide critical context that was previously missing from transaction reports. For example, the ‘Effective Date’ field will allow regulators to understand the temporal nature of a transaction’s obligations, which is particularly important for derivatives with forward-starting dates.

The ‘Entity Subject to the Reporting Obligation’ field will bring clarity to complex reporting arrangements where one firm submits a report on behalf of another. Sourcing this new information may require changes to front-office systems, trade booking workflows, and static data repositories.

The table below provides a detailed overview of some of the key new fields proposed in the RTS 22 review:

A Procedural Roadmap for Implementation

A structured, phased approach is essential for a successful transition. Firms should establish a dedicated project team with representatives from compliance, technology, operations, and the front office to oversee the implementation process. The following is a high-level procedural roadmap:

1. Phase 1 ▴ Analysis and Scoping (Q1-Q2 2025)
   • Detailed Review ▴ Conduct a line-by-line analysis of the final RTS 22 text and the accompanying technical documentation.
   • Gap Analysis ▴ Compare the new requirements against the firm’s current reporting capabilities, identifying all data, system, and process gaps.
   • Impact Assessment ▴ Evaluate the impact on all business lines and trading desks, paying close attention to the revised scope for OTC derivatives.
2. Phase 2 ▴ Design and Development (Q2-Q4 2025)
   • System Design ▴ Develop detailed technical specifications for all required system changes, including data sourcing, enrichment logic, and reporting formats.
   • Vendor Engagement ▴ Liaise with technology vendors (e.g. OMS, EMS, reporting solution providers) to understand their product roadmaps and plan for necessary upgrades.
   • Build and Configure ▴ Begin the process of building new system components and reconfiguring existing ones to meet the new requirements.
3. Phase 3 ▴ Testing and Deployment (Q1-Q2 2026)
   • Unit and Integration Testing ▴ Conduct thorough testing of all individual system components and their interactions.
   • User Acceptance Testing (UAT) ▴ Engage business users to validate the accuracy and completeness of the reports in a test environment.
   • Parallel Run ▴ If feasible, conduct a parallel run, generating reports under both the old and new standards to compare the output and identify any discrepancies.
   • Deployment ▴ Deploy the new solution into the production environment ahead of the official go-live date.

A phased implementation, starting with a deep gap analysis and culminating in a parallel run, is the optimal execution strategy for the RTS 22 changes.

Case Study a Complex Derivative Trade

To illustrate the practical impact of these changes, consider a scenario where an investment firm executes a complex, multi-leg OTC interest rate swap on behalf of a client, which is then allocated to several sub-accounts. Under the proposed RTS 22, the reporting of this transaction would be significantly more detailed. The report would need to include the new ‘Effective Date’ field, specifying the future date on which the swap’s obligations begin. The ‘Client Categorisation’ field would identify the client as a professional investor.

Most importantly, the use of the new INTC identifiers would be critical to link the initial block trade with the subsequent allocations to the sub-accounts. This creates an auditable trail that allows regulators to see the full lifecycle of the trade, from the aggregated order to the individual client allocations. This level of granularity is a substantial step up from the current requirements and will require significant enhancements to how firms capture and link trade data.

Reflection

A Systemic Recalibration

The forthcoming adjustments to RTS 22 are more than a regulatory update; they represent a fundamental recalibration of the market’s data nervous system. The success of an institution’s response will hinge on its ability to perceive these changes not as isolated technical hurdles, but as integral components of a broader movement toward a more transparent and interconnected regulatory environment. The emphasis on harmonization with EMIR and the proactive inclusion of DLT instruments signal a clear trajectory.

The future of financial regulation lies in data consistency and technological adaptability. Viewing the implementation process through this lens transforms it from a compliance burden into a strategic investment in a more resilient and efficient operational architecture, one that is prepared for the continued evolution of global financial markets.
