## Concept

The implementation of the Markets in Financial Instruments Directive II (MiFID II) fundamentally recalibrated the responsibilities of investment firms, particularly concerning the principle of best execution. This directive moved beyond its predecessor’s framework, embedding a more rigorous and evidence-based discipline into the fabric of trade execution. For the [Request for Quote](https://prime.greeks.live/area/request-for-quote/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (RFQ) market, a domain traditionally characterized by bilateral negotiations and established relationships, this shift was particularly transformative. The core change was the elevation of the best execution standard from requiring “all reasonable steps” to demanding “[all sufficient steps](https://prime.greeks.live/area/all-sufficient-steps/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite),” a semantic alteration with profound operational consequences.

This change compelled firms to dismantle informal, relationship-based [counterparty selection](https://prime.greeks.live/area/counterparty-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) practices and replace them with a structured, data-driven methodology capable of withstanding intense regulatory examination. The directive necessitated a systematic approach where every decision in the RFQ lifecycle, especially the choice of which [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to invite, had to be justifiable and documented.

## The Mandate for Demonstrable Fairness

At the heart of [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s impact on [RFQ workflows](https://prime.greeks.live/area/rfq-workflows/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is the concept of demonstrability. The directive shifted the burden of proof squarely onto the investment firm to evidence that its processes were designed to achieve the best possible outcome for the client. This had a direct effect on counterparty selection, as firms could no longer rely on implicit understandings or historical ties.

Instead, they were required to establish and maintain a formal [Order Execution Policy](https://prime.greeks.live/area/order-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that explicitly detailed the criteria for selecting [execution venues](https://prime.greeks.live/area/execution-venues/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), a category that includes the market makers and liquidity providers who respond to RFQs. This policy became the foundational document against which a firm’s execution practices would be judged.

The “legitimate reliance” test, carried over from MiFID I but applied with greater rigor, became a critical gateway. [Best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) obligations for an [RFQ](https://prime.greeks.live/area/rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) are triggered when a client is deemed to be legitimately relying on the firm to protect their interests. This is assessed through a four-fold test considering who initiated the trade, prevailing market practices, the degree of price transparency, and the nature of the firm-client relationship.

MiFID II forced firms to formalize the application of this test, creating an internal, auditable record of why best execution was, or was not, applicable to a given RFQ. This initial step dictates the level of diligence required for the subsequent counterparty selection.

> The directive transformed best execution from a passive compliance exercise into an active, evidence-based discipline that permeates the entire RFQ workflow.

## From Relationship to Rationale

The most significant change was the move away from a purely qualitative, relationship-based approach to counterparty selection towards one grounded in objective rationale. Before MiFID II, a trader might send an RFQ to a handful of trusted counterparties based on experience and personal rapport. Post-MiFID II, that same trader needs to operate within a framework that justifies the inclusion of each counterparty on the list. This framework is built upon a set of predefined, objective criteria that are consistently applied and periodically reviewed.

These criteria typically include factors such as:

- **Historical Quoting Performance** ▴ Analyzing a counterparty’s past performance, including the competitiveness of their pricing, the speed of their responses, and their fill ratios.

- **Instrument Expertise** ▴ Ensuring the counterparty has a demonstrable specialization and provides consistent liquidity in the specific asset class or financial instrument being traded.

- **Creditworthiness and Counterparty Risk** ▴ A formal assessment of the counterparty’s financial stability and the associated settlement risk.

- **Operational Efficiency** ▴ The reliability and robustness of their technological infrastructure and post-trade processing capabilities.

By formalizing these criteria, MiFID II forced firms to create a dynamic and defensible list of approved counterparties. This list is not static; it is subject to ongoing monitoring and review, with underperforming counterparties being removed and new ones added based on their ability to meet the firm’s objective standards. This continuous evaluation process is a direct consequence of the “all [sufficient steps](https://prime.greeks.live/area/sufficient-steps/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” mandate, as it ensures the firm is actively seeking the best possible execution venues for its clients on an ongoing basis.

## Strategy

The strategic response to MiFID II’s best execution requirements involved a fundamental re-architecting of the internal governance and technological infrastructure surrounding RFQ workflows. Firms had to move beyond mere compliance and develop a strategic framework that embedded the principles of the directive into their daily operations. This framework was built on two primary pillars ▴ the creation of a robust and defensible Order [Execution Policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and the implementation of a data-capture and analysis capability that could provide the evidence needed to support it. The strategy was to transform the RFQ process from an art into a science, where counterparty selection was the output of a systematic, repeatable, and auditable process.

## Architecting a Defensible Execution Policy

The cornerstone of a firm’s MiFID II strategy for RFQs is its [Order Execution](https://prime.greeks.live/area/order-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Policy. This document is not a static legal disclosure but a living operational blueprint that guides every stage of the execution process. For counterparty selection, the policy must clearly articulate the methodology for choosing and evaluating liquidity providers. This involves defining the specific [execution factors](https://prime.greeks.live/area/execution-factors/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that the firm will consider and their relative importance.

While price is a critical factor, MiFID II explicitly requires firms to consider a broader range of elements to achieve the best possible result. The strategic challenge was to define and weight these factors in a way that was appropriate for the firm’s client base and business model. The table below illustrates a typical strategic framework for weighting execution factors in an RFQ context.

### Table 1 ▴ Execution Factor Weighting Framework for RFQ Counterparty Selection

| Execution Factor | Description | Strategic Importance (Illustrative Weighting) | Rationale |
| --- | --- | --- | --- |
| Price | The quoted price for the financial instrument. This includes not just the headline price but also any associated costs or charges. | High (40%) | The primary determinant of the total consideration for the transaction and a key component of the best execution outcome. |
| Likelihood of Execution | The probability that the counterparty will honor its quote and that the trade will settle successfully. This incorporates an assessment of the counterparty’s reliability and operational stability. | High (30%) | A competitive quote is of little value if the trade fails to execute or settle. This factor is critical for ensuring certainty of execution, especially in volatile markets or for large-sized orders. |
| Speed and Quality of Response | The timeliness and consistency of the counterparty’s quoting behavior. This includes the time taken to respond to an RFQ and the frequency with which they provide competitive quotes. | Medium (15%) | A fast and reliable quoting service allows the firm to act on market opportunities quickly and efficiently. Slow or inconsistent responders can introduce opportunity cost. |
| Size and Nature of the Order | The counterparty’s ability to handle orders of a particular size without causing adverse market impact. This also considers their expertise in specific, less liquid instruments. | Medium (10%) | Selecting counterparties with the capacity to absorb large orders is crucial for minimizing market impact and information leakage. |
| Counterparty Risk | The financial health and creditworthiness of the counterparty. This is a qualitative overlay to the quantitative factors. | Low (5%) | While important, this is often treated as a binary gateway (i.e. a counterparty must meet a minimum credit standard to be considered) rather than a primary selection driver for individual trades. |

This framework provides a structured and consistent approach to evaluating counterparties, moving the decision-making process away from subjective preference and towards a model that can be objectively defended. The weightings are not fixed; they can be adjusted based on the specific characteristics of the client, the order, and the prevailing market conditions, but any deviation from the standard policy must be documented and justified.

## Implementing a Data-Driven Monitoring System

A policy without data is merely a statement of intent. The second pillar of the strategy was the implementation of systems to capture, store, and analyze data from every RFQ transaction. This created a feedback loop that allowed firms to monitor the effectiveness of their execution policy and the performance of their selected counterparties in near real-time. This internal data infrastructure became the engine of MiFID II compliance for RFQs.

> The strategic imperative of MiFID II was to create an unbroken, evidence-based chain of command from policy to execution.

The data captured typically includes:

- **Timestamp Data** ▴ Precise timestamps for when the RFQ was sent, when each quote was received, and when the trade was executed.

- **Quote Data** ▴ The price and size of every quote received from every counterparty, even the losing quotes.

- **Execution Data** ▴ The final execution price, size, and the identity of the winning counterparty.

- **Contextual Data** ▴ Information about the market conditions at the time of the RFQ, such as the prevailing bid-ask spread on a lit market (if available) or other relevant pricing sources.

This data feeds into an internal [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ([TCA](https://prime.greeks.live/area/tca/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) system designed for RFQ workflows. Unlike traditional TCA, which often benchmarks against metrics like VWAP, RFQ TCA focuses on “peer-based” benchmarks. The primary measure of execution quality is the performance of the winning quote relative to the other quotes received in the same RFQ.

This “quote-to-trade” analysis allows the firm to demonstrate, on a trade-by-trade basis, that it selected the best available quote based on its predefined execution factors. Furthermore, by aggregating this data over time, the firm can generate performance reports for each counterparty, providing the quantitative evidence needed to justify their continued inclusion on the approved list.

## Execution

The execution of a MiFID II-compliant RFQ [counterparty selection process](https://prime.greeks.live/question/how-does-counterparty-selection-in-an-rfq-mitigate-adverse-selection-risk/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) requires a disciplined, technology-driven approach. It translates the strategic framework and the formal policy into a set of repeatable operational procedures that are embedded in the firm’s trading workflow. This operationalization is characterized by a pre-trade selection and justification process, a real-time monitoring capability, and a post-trade review and governance cycle. The entire process is designed to produce a comprehensive audit trail that can be used to demonstrate compliance with the “all sufficient steps” obligation to regulators and clients.

## The Operational Playbook for Counterparty Selection

The day-to-day execution of the counterparty selection process follows a clear, multi-stage procedure. This playbook ensures that every RFQ is handled in a consistent and compliant manner.

- **Pre-Trade Counterparty Filtering** ▴ Before an RFQ is initiated, the trading system or the trader consults the firm’s list of approved counterparties. This list is dynamically maintained by a governance committee and is based on the ongoing monitoring of [counterparty performance](https://prime.greeks.live/area/counterparty-performance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). For a specific trade, this list may be further filtered based on the instrument type, order size, and client-specific instructions.

- **Justification for Counterparty Set** ▴ The trader or the system must be able to provide a rationale for the specific set of counterparties chosen for a particular RFQ. For example, for a large, illiquid corporate bond, the selection might be limited to a small number of specialist market makers. This justification is logged electronically.

- **Systematic RFQ Dissemination** ▴ The RFQ is sent simultaneously to the selected counterparties through an electronic trading platform. This ensures a level playing field and allows for the accurate capture of timestamps and quote data.

- **Real-Time Quote Analysis** ▴ As quotes are received, they are displayed in a structured manner that allows the trader to evaluate them against the firm’s execution factors. Modern execution management systems (EMS) can automate this analysis, highlighting the best quote based on price while also displaying other relevant metrics like the counterparty’s historical fill ratio.

- **Execution and Rationale Capture** ▴ The trader executes the trade with the chosen counterparty. If the winning quote is not the one with the best price, the system requires the trader to provide a specific reason for this decision (e.g. “better likelihood of execution due to size,” “counterparty A’s quote was firm while B’s was indicative”). This rationale is a critical piece of the audit trail.

## Quantitative Modeling and Data Analysis

The backbone of the execution process is the quantitative analysis of counterparty performance. This analysis is conducted by a dedicated function, often part of a TCA or market structure group, and its findings are used to inform the governance process for managing the approved counterparty list. The table below provides an example of a [quarterly counterparty performance scorecard](https://prime.greeks.live/question/what-specific-steps-should-an-audit-committee-take-quarterly-before-ceo-certification/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which is a key output of this analysis.

### Table 2 ▴ Quarterly Counterparty Performance Scorecard (Asset Class ▴ Investment Grade Corporate Bonds)

| Counterparty | RFQ Count | Response Rate | Average Response Time (ms) | Price Competitiveness Score (vs. Best Quote) | Win Rate | Overall Score |
| --- | --- | --- | --- | --- | --- | --- |
| Liquidity Provider A | 1,520 | 98% | 250 | 95% | 35% | 92.5 |
| Liquidity Provider B | 1,480 | 95% | 450 | 98% | 40% | 94.0 |
| Liquidity Provider C | 1,250 | 99% | 300 | 85% | 15% | 82.0 |
| Liquidity Provider D | 950 | 85% | 800 | 82% | 5% | 70.5 |
| Liquidity Provider E | 1,600 | 92% | 600 | 90% | 5% | 84.5 |

_Note ▴ The Price Competitiveness Score is calculated as the percentage of times the counterparty’s quote was within a predefined tolerance of the best quote received. The Overall Score is a weighted average of the various performance metrics, aligned with the firm’s Order Execution Policy._

This type of quantitative analysis provides the firm’s governance committee with the objective data needed to make informed decisions about the composition of its counterparty list. For example, based on the scorecard above, the committee might place [Liquidity Provider](https://prime.greeks.live/area/liquidity-provider/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) D on a watch list due to its low response rate and poor price competitiveness. Conversely, it would confirm that Providers A and B are core counterparties for this asset class. This data-driven governance process is the ultimate expression of MiFID II’s “all sufficient steps” requirement in the context of [RFQ counterparty selection](https://prime.greeks.live/area/rfq-counterparty-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Reflection

The integration of MiFID II’s principles into the RFQ workflow represents a significant operational and cultural evolution. It has compelled a move from intuition-based trading to a more systematic, engineering-led approach. The knowledge and processes developed in response to this directive are more than just a compliance solution; they form a critical component of a firm’s overall execution intelligence.

The discipline of capturing data, analyzing performance, and justifying decisions creates a powerful feedback loop that can be harnessed to generate a tangible competitive advantage. The ultimate question for any firm is how it can leverage this regulatory-driven framework not just to satisfy its compliance obligations, but to build a truly superior execution capability that delivers consistently better outcomes for its clients.
