How Do Regulatory Frameworks like MiFID II Influence RFQ Panel Composition and Best Execution Duties?

Concept

The implementation of the Markets in Financial Instruments Directive II (MiFID II) represents a fundamental re-architecting of European financial markets. For institutional participants, its influence extends far beyond a mere compliance checklist, reaching into the core operational logic of how liquidity is sourced and how execution quality is defined and proven. At the heart of this transformation lies the interplay between the Request for Quote (RFQ) protocol and the mandate for best execution.

This regulation systematically compels a shift from relationship-driven institutional habits to a quantifiable, evidence-based process. The composition of an RFQ panel, once a stable construct built on long-term relationships and perceived reliability, is now a dynamic and auditable component of a firm’s execution architecture.

MiFID II operates as a set of systemic constraints and data-generation requirements that force transparency upon previously opaque bilateral trading arrangements. It mandates that firms take “all sufficient steps” to obtain the best possible result for their clients, a significant linguistic and practical escalation from the previous “all reasonable steps” standard. This obligation necessitates a profound change in the operational approach to off-book liquidity sourcing, such as the RFQ process. The directive requires firms to look past the final execution price and consider a wider set of “execution factors,” including costs, speed, and the likelihood of execution and settlement.

Consequently, the selection of counterparties for an RFQ panel can no longer be justified by convention or comfort. It must be the output of a rigorous, data-driven framework designed to demonstrably achieve superior results for the end client. This transforms the RFQ panel from a simple list of dealers into a critical, performance-measured component of a firm’s trading system.

MiFID II reframes best execution as an engineering problem, requiring firms to build, monitor, and justify a data-driven system for sourcing liquidity.

The regulation effectively dissolves the comfortable opacity that once characterized many Over-the-Counter (OTC) interactions. By requiring firms to check the fairness of prices in OTC transactions and to gather market data to support their pricing estimations, MiFID II imposes a new layer of analytical rigor. For a trader utilizing an RFQ, this means the panel of liquidity providers must be constructed and continuously evaluated based on their ability to help the executing firm meet these stringent evidential requirements.

The directive’s reach is comprehensive, forcing a systemic integration of compliance, risk, and execution functions. The result is an environment where the architecture of your trading protocols, particularly your process for soliciting quotes, is a direct reflection of your commitment to the best execution mandate.

Strategy

Navigating the post-MiFID II landscape requires a deliberate and strategic redesign of a firm’s approach to liquidity sourcing. The regulation acts as a catalyst, compelling institutions to evolve their RFQ panel management from a static, relationship-based model to a dynamic, performance-oriented one. The core strategic challenge is to build a framework that not only satisfies the regulatory text but also enhances execution quality in a measurable way. This involves a multi-layered approach that integrates data analysis, counterparty evaluation, and a clear, documented execution policy.

From Relationships to Quantifiable Performance

The primary strategic shift is the formalization of the counterparty selection process. Before MiFID II, an RFQ panel might be composed of dealers with whom the firm had long-standing relationships. While trust and reliability remain important, the directive demands that these qualitative aspects be supported by quantitative evidence.

The “best possible result” must be determined by assessing execution factors for which a firm must define the relative importance based on client type, order characteristics, and the instrument being traded. This means a firm’s strategy must center on collecting and analyzing data for every potential counterparty on its panel.

A successful strategy involves creating a virtuous cycle of performance measurement and panel optimization. This process includes:

• Data-Driven Onboarding ▴ Prospective panel members are evaluated based on predefined quantitative criteria before being added. This includes their historic performance in specific asset classes and their technological capabilities for providing timely and competitive quotes.
• Continuous Monitoring ▴ Existing panel members are subject to ongoing review. Their performance across key execution factors ▴ price competitiveness, response latency, fill rates, and post-trade settlement efficiency ▴ is tracked over time.
• Dynamic Composition ▴ The RFQ panel is treated as a dynamic entity. Underperforming counterparties are removed, and new ones that demonstrate superior performance are added. This ensures the panel remains optimized to deliver high-quality execution. The execution policy must detail the factors that would lead to a change in the list of execution venues.

What Are the Strategic Implications of Venue Selection?

MiFID II broadens the definition of an “execution venue” to include regulated markets, Multilateral Trading Facilities (MTFs), Organised Trading Facilities (OTFs), and Systematic Internalisers (SIs). This creates strategic choices for firms when constructing their RFQ workflows. An SI, for instance, is an investment firm that deals on its own account by executing client orders outside a regulated trading venue.

Including SIs on an RFQ panel can provide access to unique liquidity, but it also requires the firm to have a robust process for ensuring the prices offered are fair and consistent with their best execution obligations. The strategy must account for the different characteristics of each venue type and justify their inclusion in the execution policy.

Under MiFID II, the RFQ panel ceases to be a simple address book and becomes a managed portfolio of liquidity sources, optimized for performance against auditable metrics.

The table below illustrates the strategic evolution of RFQ panel management driven by the regulation.

Ultimately, the strategy is one of systemization. It involves building an internal infrastructure capable of capturing the necessary data, performing the required analysis, and producing the documentation to prove that “all sufficient steps” were taken. This transforms the best execution obligation from a qualitative goal into a quantifiable, operational discipline.

Execution

The execution of a MiFID II-compliant RFQ strategy is a matter of operational precision and technological integration. It requires translating the high-level principles of best execution into a granular, repeatable, and auditable workflow. This operational playbook centers on the systematic use of data to construct, manage, and justify every decision within the RFQ process, from counterparty selection to post-trade analysis.

The Operational Playbook for Panel Management

Implementing a robust RFQ panel management system under MiFID II involves a clear, multi-step process. This is a procedural guide designed to ensure that the firm’s execution policy is not just a document, but a living framework that governs daily trading activity.

1. Define Quantitative Evaluation Criteria ▴ The first step is to establish a precise set of metrics against which all potential and current panel members will be judged. These criteria must align with the MiFID II execution factors. The firm must decide on the relative importance of these factors for different asset classes and client types.
2. Implement A Data Capture Architecture ▴ A system must be in place to capture every relevant data point from the RFQ lifecycle. This includes the timestamp of the RFQ, the timestamps and content of all quotes received, the chosen quote, and the final execution details. This data forms the bedrock of the entire execution framework.
3. Establish A Formal Review Cadence ▴ The firm must define a regular schedule for reviewing the performance of its RFQ panel. This could be quarterly or semi-annually. The review process uses the captured data to score each counterparty against the predefined criteria.
4. Document All Decisions ▴ Every decision regarding the composition of the RFQ panel ▴ adding a new counterparty, removing an existing one, or maintaining the status quo ▴ must be formally documented. This documentation should explicitly reference the data and analysis that supports the decision, creating a clear audit trail.
5. Integrate With The Order Execution Policy ▴ The panel management process must be explicitly described within the firm’s overall order execution policy. This policy document should explain to clients how the firm selects execution venues (including RFQ counterparties) to deliver the best possible result.

How Does Data Systematically Drive Panel Selection?

The core of the execution process is the systematic analysis of counterparty performance. This moves the selection process from the realm of subjective preference to objective evaluation. A quantitative model is essential for this task. The table below provides a simplified example of a counterparty scoring matrix that could be used in a quarterly review process for a corporate bond RFQ panel.

In this model, Dealer C’s consistent underperformance on price and fill rate would flag them for potential removal from the panel, backed by clear quantitative evidence. The strong performance of Dealer A, B, and D justifies their continued inclusion.

Effective execution under MiFID II is achieved when every RFQ is treated as a data point in a continuous feedback loop that optimizes for provable execution quality.

Why Is Post-Trade Analysis so Important?

The obligation does not end when the trade is executed. MiFID II’s reporting requirements, particularly the annual RTS 28 report, compel firms to publish information about the top five execution venues they used for each class of financial instruments. This necessitates a robust Transaction Cost Analysis (TCA) framework that can analyze RFQ execution quality after the fact. This analysis feeds directly back into the counterparty evaluation process.

For an RFQ, TCA might involve comparing the winning quote against a benchmark, such as the best price available from a consolidated tape or the volume-weighted average price (VWAP) over a short interval. This post-trade evidence is the final, critical piece of the puzzle, providing the definitive proof that the firm’s execution process is designed and operated to achieve the best possible result for its clients.

Reflection

From Mandate to Mechanism

The integration of MiFID II’s principles into a firm’s operational DNA is an ongoing process. The frameworks and procedures detailed here represent the current state of a continuously evolving system. The regulation provides the architectural constraints, but the truly effective execution systems are those that treat these constraints as a catalyst for innovation. The core challenge moving forward is one of dynamic adaptation.

As market structures shift and data sources become richer, how will your firm’s definition of “best execution” evolve? Is your data architecture flexible enough to incorporate new metrics and analytical techniques?

The ultimate goal is to build a system of execution that is not merely compliant, but intelligent. A system that learns from every transaction and refines its own logic over time. Viewing the regulatory framework as a fixed endpoint is a strategic error.

Instead, it should be seen as the foundation upon which a more sophisticated, data-driven, and ultimately more effective trading architecture can be built. The quality of that architecture will be a defining factor in achieving a sustainable competitive advantage in the markets of the future.
