Can a Firm Use a Single Dealer RFQ and Still Be Compliant with MiFID II Best Execution Rules?

Concept

A firm can utilize a single-dealer Request for Quote (RFQ) protocol and maintain compliance with MiFID II’s best execution obligations. This pathway, however, is exceptionally narrow and carries a substantial evidentiary burden. The core of the matter resides not in the mechanism of the RFQ itself, but in the firm’s demonstrable ability to consistently achieve the best possible result for its clients through this solitary channel. The architecture of MiFID II’s best execution framework is built upon the principle of “all sufficient steps,” a standard that demands a proactive and empirical approach to validating execution quality.

When a firm elects to restrict its liquidity access to a single counterparty, it voluntarily assumes the full weight of proving that this decision systematically benefits the end client. This is a profound departure from a multi-venue approach where competition among dealers provides an inherent, albeit incomplete, validation of price competitiveness.

The regulatory framework acknowledges the existence and utility of bilateral trading arrangements, particularly for less liquid instruments or large-in-scale orders where an RFQ to a single, specialized dealer may be the most effective method for sourcing liquidity without causing adverse market impact. The critical determinant of compliance shifts from the breadth of dealers queried to the depth and rigor of the firm’s internal validation processes. The firm must construct an operational system capable of continuously monitoring, analyzing, and documenting that its chosen single-dealer arrangement consistently delivers outcomes superior to, or at a minimum equivalent to, those achievable through alternative execution venues. This requires a sophisticated data infrastructure and a meticulously designed execution policy that is both forward-looking in its expectations and backward-looking in its analysis of performance.

A firm’s compliance hinges on its ability to prove that a single-dealer RFQ consistently yields the best possible client outcome.

What Defines the Best Execution Obligation under MiFID II?

The MiFID II best execution obligation, articulated in Article 27 of the Directive, compels investment firms to take “all sufficient steps” to obtain the best possible result for their clients. This is a more demanding standard than the “all reasonable steps” required under MiFID I. The result is assessed against a range of execution factors, including price, costs, speed, likelihood of execution and settlement, size, nature of the order, and any other relevant consideration. For professional clients, the firm has the discretion to determine the relative importance of these factors based on the client’s characteristics, the order’s specifics, the financial instrument’s nature, and the potential execution venues. This framework applies universally across all financial instruments, including those traded over-the-counter (OTC) via RFQ protocols.

The regulation does not prescribe the use of multiple venues; it mandates a result. A firm’s execution policy can, in theory, specify a single venue. However, this is permissible only if the firm can substantiate that this single point of access consistently produces the best outcome for clients.

The Legitimate Reliance Test in RFQ Markets

A crucial consideration, particularly in the context of a firm trading on its own account in response to a client’s RFQ, is the “legitimate reliance test.” This test helps determine whether the full best execution obligations apply. Originating under MiFID I but remaining relevant, this four-fold cumulative test assesses whether the client legitimately relies on the firm to protect its interests. The factors considered are ▴ who initiates the transaction, prevailing market practices (such as the commonality of “shopping around”), the relative price transparency of the market, and the nature of the relationship as presented by the firm. When a client, especially a professional one, actively solicits a quote from a single dealer, it can be argued that their reliance is diminished.

However, the firm receiving the request is not entirely absolved. It must still ensure the price offered is fair, a requirement that necessitates its own internal price validation against available market data. This is a critical safeguard within the single-dealer RFQ model.

Strategy

The strategic decision to employ a single-dealer RFQ model is a calculated trade-off between operational simplicity and regulatory scrutiny. It requires the construction of a robust compliance architecture designed to preemptively answer the inevitable questions from regulators about the integrity of the execution process. The strategy is not simply to use one dealer, but to build a system that perpetually validates this choice.

This involves creating a feedback loop where pre-trade analysis, execution data, and post-trade verification work in concert to build a comprehensive evidence file for every transaction. The objective is to move from a subjective belief in a dealer’s quality to an objective, data-driven proof of superior and consistent performance.

Comparing Single-Dealer and Multi-Dealer RFQ Models

The choice between a single-dealer and a multi-dealer RFQ framework has significant strategic implications for a firm’s trading operations and compliance posture. While a multi-dealer RFQ provides a natural competitive environment for price discovery, a single-dealer RFQ may be strategically advantageous in specific circumstances, provided the firm implements a rigorous validation framework. The following table compares the two models across the key best execution factors.

Building a Defensible Single-Dealer Execution Policy

A compliant single-dealer RFQ strategy requires a meticulously crafted execution policy. This policy is the firm’s foundational document, outlining the rationale and processes that ensure MiFID II compliance. It must be a living document, subject to regular review and supported by a robust data collection and analysis framework.

1. Define the Scope Clearly articulate the specific circumstances under which a single-dealer RFQ is deemed appropriate. This could be based on asset class, order size, liquidity profile, or specific client instructions. The policy must justify why this approach is superior to alternatives in these defined scenarios.
2. Establish a Dealer Selection and Review Process The policy must detail the criteria for selecting the single dealer. This includes assessing their financial stability, market expertise, and historical execution quality. A periodic, data-driven review process must be in place to ensure the chosen dealer continues to provide best execution on a consistent basis.
3. Implement a Fair Price Verification Protocol This is the cornerstone of the strategy. The policy must specify the independent market data sources that will be used to verify the fairness of the dealer’s quotes. This could include consolidated tape data, independent pricing services, or indicative quotes from other sources. The methodology for comparison and the tolerance for deviations must be clearly defined.
4. Develop a Rigorous Monitoring and Reporting Framework The firm must have systems in place to monitor the effectiveness of its single-dealer policy. This includes regular reporting on execution quality metrics and exception-based reviews of trades that fall outside predefined parameters. This monitoring must be independent of the trading function.
5. Document Everything Every decision, from the selection of the dealer to the verification of each trade, must be documented. This creates the necessary audit trail to demonstrate to regulators that the firm is taking “all sufficient steps” to achieve the best possible result for its clients.

Execution

The execution of a compliant single-dealer RFQ strategy is an exercise in operational precision and data discipline. It transforms the trading process from a simple act of price-taking into a systematic process of evidence generation. The firm’s infrastructure must be engineered to capture, analyze, and store the necessary data points to construct a defensible narrative for each transaction. This operational rigor is what separates a compliant firm from one that is merely taking a regulatory shortcut.

In a single-dealer RFQ model, the quality of the evidence trail is as important as the quality of the execution itself.

Data Collection for Compliance Audits

To withstand regulatory scrutiny, a firm must be able to produce a comprehensive data file for any given trade executed via a single-dealer RFQ. This file must provide a complete picture of the execution process, from the initial order to the post-trade analysis. The following table outlines the critical data points that must be collected and maintained.

How Should a Firm Conduct Price Fairness Checks?

For OTC instruments traded via a single-dealer RFQ, the obligation to “check the fairness of the price” is paramount. This is an active, not a passive, process. A firm cannot simply accept the dealer’s quote at face value. It must have a systematic procedure for verification.

• Gathering Market Data Before or at the time of the RFQ, the firm must gather relevant market data to establish a fair value range. For liquid instruments, this might be the current bid-ask spread from a regulated market. For illiquid instruments, this is more challenging and may require gathering data from multiple sources, such as pricing services, recent transaction data (if available), or even matrix pricing based on comparable instruments.
• Comparing with Similar Products Where possible, the firm should compare the quote for the bespoke OTC product with the prices of similar or comparable products. For example, the price of an off-the-run bond could be compared to the on-the-run equivalent, with adjustments for liquidity and credit risk. This demonstrates a thoughtful approach to price validation.
• Documenting the Comparison The entire process must be documented. This includes the sources of the market data used, the methodology for the comparison, and the conclusion reached about the fairness of the dealer’s quote. This documentation is the firm’s primary defense in a regulatory inquiry.

Ultimately, the successful execution of a single-dealer RFQ strategy under MiFID II is a testament to a firm’s commitment to building an institutional-grade operational framework. It requires investment in technology, data, and personnel, but for firms that can meet this high bar, it offers a powerful tool for achieving specific execution objectives while remaining squarely within the bounds of their regulatory obligations.

Reflection

The analysis of single-dealer RFQs within the MiFID II framework moves the conversation beyond mere compliance and into the realm of operational architecture. The regulations provide the blueprint, but the integrity of the final structure depends entirely on the quality of the materials and the precision of the assembly. A firm’s execution policy is its strategic design, and its data infrastructure is the foundation upon which that design rests. Reflect on your own operational framework.

Is it designed simply to meet the letter of the law, or is it engineered to generate a superior, verifiable result? The capacity to prove consistent best execution through a constrained channel is a powerful indicator of a firm’s systemic intelligence and its ultimate commitment to the clients it serves.
