## Concept

The mandate to document the justification for Request for Quote (RFQ) [counterparty selection](https://prime.greeks.live/area/counterparty-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) under [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a foundational element of modern execution architecture. It represents a systemic shift, embedding accountability and data-driven decision-making into the very core of over-the-counter (OTC) and off-book trading protocols. This requirement compels an investment firm to construct and maintain a verifiable, auditable record that demonstrates how its choice of counterparties aligns with its overarching duty to achieve the best possible result for its clients.

The process transforms the selection of a trading partner from a purely relationship-based or convenience-driven decision into a rigorous, evidence-backed analytical exercise. At its heart, this documentation serves as the connective tissue between a firm’s stated [best execution policy](https://prime.greeks.live/area/best-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and its daily operational reality.

Understanding this obligation requires viewing the market not as a monolithic entity, but as a complex system of interconnected liquidity pools, each with distinct characteristics. The [RFQ](https://prime.greeks.live/area/rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) protocol itself is a mechanism for targeted liquidity discovery, allowing a firm to solicit prices for a specific [financial instrument](https://prime.greeks.live/area/financial-instrument/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) from a chosen set of counterparties. MiFID II intervenes at this critical juncture, demanding a clear rationale for why specific counterparties were invited to quote while others were not. This is a direct response to the inherent opacity of bilateral trading arrangements.

The regulation seeks to ensure that client interests remain the primary driver in a protocol that, by its nature, limits broad market participation. The justification, therefore, becomes a formal declaration of the strategic and quantitative reasoning that underpins each instance of targeted engagement.

## The Regulatory Architecture of Best Execution

The obligation to document counterparty selection is rooted in Article 27 of MiFID II and further detailed in the accompanying [Regulatory Technical Standard](https://prime.greeks.live/area/regulatory-technical-standard/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (RTS) 28. These regulations establish the principle of “all sufficient steps” that a firm must take to obtain the best possible outcome for its clients. This standard is a significant elevation from the previous “all reasonable steps” requirement, implying a more proactive and evidence-based approach.

The documentation of [RFQ counterparty](https://prime.greeks.live/area/rfq-counterparty/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) choice is a direct manifestation of this heightened standard. It provides regulators, clients, and internal compliance functions with a transparent window into the firm’s execution decision-making process, ensuring that factors like price, cost, speed, likelihood of execution, and other qualitative considerations are systematically evaluated.

> The documentation of RFQ counterparty selection serves as the definitive record linking a firm’s execution policy to its operational actions.

The framework effectively creates a chain of accountability. It begins with the firm’s high-level best [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which must outline the criteria used to select execution venues and counterparties. This policy is the strategic blueprint. The documentation for each RFQ then serves as the tactical proof of that blueprint’s implementation.

It must demonstrate that the chosen counterparties for a specific trade were selected based on their consistent ability to meet the criteria laid out in the policy, especially in the context of the specific instrument, trade size, and prevailing market conditions. This creates a feedback loop where the firm’s overarching strategy is continuously validated or challenged by the granular data of its daily trading activities.

## Systemic Internaliser and Counterparty Dynamics

A crucial component of this ecosystem is the role of the [Systematic Internaliser](https://prime.greeks.live/area/systematic-internaliser/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (SI). An SI is an investment firm that, on an organised, frequent, systematic, and substantial basis, deals on its own account when executing client orders outside a regulated market, MTF, or OTF. When a firm sends an RFQ to an SI, it is engaging with a principal liquidity provider. MiFID II’s rules are designed to ensure that this bilateral engagement does not disadvantage the client.

The justification for selecting a particular SI, or a group of them, must be robust. It needs to show that the choice was made not for the convenience of the firm, but because those SIs have a demonstrable track record of providing competitive pricing, deep liquidity, and reliable execution for the specific [asset class](https://prime.greeks.live/area/asset-class/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in question. The documentation must therefore capture the rationale behind why one SI’s capital was accessed over another’s, or why an SI was chosen over a multilateral venue.

This creates a competitive dynamic among liquidity providers. To be included in a firm’s RFQ process, a counterparty must consistently perform well against the key [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) metrics. The documentation process, in effect, becomes the firm’s internal ledger of counterparty performance.

It forces a systematic and periodic review of all potential counterparties, weeding out those who fail to provide competitive terms and elevating those who consistently contribute to achieving [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This data-driven approach moves the selection process beyond legacy relationships and towards a more meritocratic system where execution quality is the primary currency.

## Strategy

A robust strategy for documenting [RFQ counterparty selection](https://prime.greeks.live/area/rfq-counterparty-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is built upon a dual-pillar framework that integrates both quantitative and qualitative analysis. This framework serves as the firm’s internal operating system for compliance and execution optimization. The objective is to create a systematic, repeatable, and defensible process for every RFQ sent.

The strategy moves beyond simple record-keeping; it is about constructing a dynamic decision-making engine that actively guides traders toward compliant and high-performing execution pathways. The foundation of this engine is the firm’s Best Execution Policy, which must explicitly define the factors and weightings used to evaluate and select counterparties.

The strategic implementation begins with the formal classification of execution factors. These factors are the criteria against which all potential counterparties are measured. The firm must define, in writing, what these factors are and how they are prioritized. This prioritization is not static; it is a dynamic process that adapts to the specific context of each order, considering the client’s instructions, the nature of the financial instrument, the size of the order, and the prevailing market conditions.

For instance, for a large, illiquid block trade in a corporate bond, the likelihood of execution and settlement certainty may take precedence over marginal price improvement. Conversely, for a standard-sized trade in a liquid FX spot contract, price and speed will be the dominant factors. The strategy must be flexible enough to accommodate this contextual shifting of priorities while maintaining a consistent and auditable logic.

## The Quantitative and Qualitative Assessment Matrix

The core of the selection strategy is the development of a comprehensive [assessment matrix](https://prime.greeks.live/question/how-can-transaction-cost-analysis-be-integrated-into-real-time-counterparty-risk-assessment-protocols/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This matrix operationalizes the best execution policy by assigning measurable criteria to both quantitative and [qualitative factors](https://prime.greeks.live/area/qualitative-factors/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). It becomes the primary tool for both pre-trade selection and post-trade review.

## Quantitative Factors the Hard Data of Execution

Quantitative factors are the empirical measures of execution quality. They form the objective bedrock of any counterparty assessment. A sophisticated strategy involves the continuous capture and analysis of these data points for every counterparty a firm interacts with.

- **Price Competitiveness** ▴ This involves analyzing the spread and final price offered by a counterparty relative to the market’s prevailing best bid and offer (BBO) at the time of the RFQ. The analysis should track the frequency and magnitude of price improvement offered.

- **Cost of Execution** ▴ This includes all explicit costs associated with trading with the counterparty. It covers execution fees, clearing and settlement charges, and any other ancillary costs that impact the net price of the transaction.

- **Speed of Response and Execution** ▴ The strategy must define how latency is measured. This includes the time taken for a counterparty to respond to an RFQ and the time from quote acceptance to final execution confirmation. In volatile markets, this speed can be a decisive factor.

- **Likelihood of Execution** ▴ This metric tracks the fill rate or the certainty of execution once a quote is accepted. A counterparty that frequently requotes or rejects trades after acceptance would score poorly on this factor.

## Qualitative Factors the Nuances of Partnership

Qualitative factors assess the aspects of a counterparty that are not easily reducible to a single number but are critical for risk management and operational stability. These factors require a structured, yet judgmental, assessment.

A firm’s strategy must include a formal process for scoring these qualitative aspects, often through periodic reviews and [due diligence](https://prime.greeks.live/area/due-diligence/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) questionnaires. This transforms subjective assessments into structured data points within the overall matrix.

### Table 1 ▴ Qualitative Counterparty Assessment Framework

| Factor | Assessment Criteria | Data Sources | Scoring Method |
| --- | --- | --- | --- |
| Creditworthiness | Counterparty’s credit rating, balance sheet strength, and perceived default risk. | Public credit ratings (S&P, Moody’s), internal credit risk analysis, CDS spreads. | Tiered rating (e.g. 1-5 scale) based on credit rating and internal assessment. |
| Operational & Settlement Efficiency | Rate of settlement fails, efficiency of communication, ability to handle non-standard settlement instructions. | Internal settlement data, operational incident logs, feedback from back-office teams. | Scoring based on settlement fail rate and qualitative feedback from operations. |
| Technological Capability | Quality of FIX connectivity, API stability, support for required order types and protocols. | IT due diligence reports, uptime statistics, trader feedback on system performance. | Binary (Pass/Fail) for essential capabilities and a graded score for performance. |
| Liquidity & Market Access | Demonstrated ability to provide liquidity in specific asset classes, especially in stressed markets. Access to unique or specialized liquidity pools. | Historical trade data analysis, trader assessments, market intelligence. | Graded score based on asset class specialization and performance during volatility. |

## How Should a Firm Structure Its Counterparty Scoring System?

The culmination of this strategy is a weighted scoring system. This system combines the quantitative and qualitative assessments into a single, composite score for each counterparty, often tailored by asset class. This provides a data-driven foundation for the trader’s ultimate decision. The strategy must clearly articulate how these weights are determined and under what circumstances they might be adjusted.

> A dynamic counterparty scoring system provides the strategic framework for justifying execution decisions on a systematic basis.

For example, for high-touch, illiquid instruments, qualitative factors like settlement efficiency and creditworthiness might receive a higher weighting. For low-touch, highly liquid electronic trading, quantitative factors like price and speed would be weighted more heavily. This weighted scoring model is not designed to replace trader discretion entirely. Instead, it provides a defensible baseline.

A trader can choose to deviate from the highest-scoring counterparty, but the documentation must then capture the specific reason for this deviation ▴ for example, a specific client instruction or a unique piece of market intelligence relevant to that particular trade. This “exception-based” documentation is a critical component of a compliant and intelligent execution strategy.

## Execution

The execution of a MiFID II-compliant RFQ documentation process is a matter of meticulous system design and operational discipline. It requires the integration of technology, process, and governance to create a seamless workflow that captures the necessary justification data with minimal friction to the trading process. The goal is to build an architecture where the act of documentation is an automated or semi-automated byproduct of the trading workflow itself, rather than a burdensome post-trade manual task. This ensures the integrity and timeliness of the data, making the [justification record](https://prime.greeks.live/question/what-is-the-primary-justification-for-allowing-safe-harbors-to-override-the-automatic-stay/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) a true reflection of the decision-making process at the point of execution.

This operational playbook can be broken down into three distinct phases ▴ pre-trade preparation, at-trade capture, and post-trade analysis. Each phase has its own set of procedures and technological requirements that collectively form the firm’s auditable evidence of compliance. The entire system is designed to answer the fundamental question from a regulator or client ▴ “For this specific trade, show me why you chose these counterparties and how that choice aligned with your duty of best execution.”

## The Operational Playbook a Three Phase Approach

This playbook details the end-to-end process for creating and maintaining the justification record. It is a procedural guide for building a robust and defensible documentation system.

![A sophisticated, multi-component system propels a sleek, teal-colored digital asset derivative trade.

## Phase 1 Pre-Trade Counterparty Management

The foundation of any justification is the universe of eligible counterparties. The pre-trade phase involves the systematic onboarding, approval, and classification of all potential trading partners. This is a function typically shared between the front office, compliance, and credit risk teams.

- **Initial Due Diligence** ▴ Before a counterparty can receive an RFQ, it must pass a formal due diligence process. This involves collecting and verifying information related to its regulatory status, financial stability, and operational capabilities.

- **Risk Assessment** ▴ A formal credit and operational risk assessment is conducted. This produces the initial scores for the qualitative factors in the assessment matrix, such as creditworthiness and settlement efficiency.

- **System Configuration** ▴ Once approved, the counterparty is configured in the firm’s [Order Management System](https://prime.greeks.live/area/order-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (OMS) or Execution Management System (EMS). Crucially, it is tagged with relevant data, including its asset class specializations, approved trading limits, and its initial qualitative scores. This configured data provides the basis for automated filtering in the at-trade phase.

- **Periodic Review Cycle** ▴ The playbook must mandate a regular review of all approved counterparties (e.g. annually). This review updates the qualitative and quantitative scores based on recent performance and any changes in the counterparty’s status. Counterparties that consistently underperform are flagged for potential offboarding.

## Phase 2 At-Trade Justification Capture

This is the most critical phase, where the actual selection decision is made and documented. The key is to capture the rationale contemporaneously with the trade. Modern EMS platforms are designed to facilitate this process.

> The at-trade justification record is the primary piece of evidence demonstrating that a firm has met its regulatory obligations for a given transaction.

When a trader initiates an RFQ, the system should perform the following steps:

- **Automated Filtering** ▴ The EMS should automatically present the trader with a list of suggested counterparties. This list is generated by filtering the firm’s universe of approved counterparties based on pre-defined criteria ▴ the specific instrument, trade size, and potentially the client’s profile.

- **Display of Key Metrics** ▴ Alongside the list of names, the system should display the key performance indicators (KPIs) for each potential counterparty, drawn from the assessment matrix. This includes metrics like average response time, historical price competitiveness for that asset, and the internal qualitative score.

- **Trader Selection and Override** ▴ The trader selects the counterparties to include in the RFQ. If the trader chooses to include a counterparty that is not on the system’s recommended list, or exclude one that is, the system should prompt for a specific justification. This is a critical control point. The reason for the override (e.g. “Counterparty X has shown specific interest in this issuer,” “Counterparty Y is known to be unwinding a large position”) is captured in a structured data field.

- **Automated Logging** ▴ The system must automatically log the following information for the [audit trail](https://prime.greeks.live/area/audit-trail/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite):

<li>The timestamp of the RFQ.

- The full list of counterparties that the RFQ was sent to.

- The justification code or text for any deviation from the system’s recommendation.

- The quotes received from each counterparty.

- The timestamp of the execution and the identity of the winning counterparty.

</li>

This automated logging creates the core of the justification record. It provides a detailed, time-stamped narrative of the selection and execution process.

## What Data Must Be in the Final Audit Record?

The final audit record, often stored in a dedicated compliance warehouse, must be comprehensive. The table below details the essential data fields that constitute a complete justification record for a single RFQ.

### Table 2 ▴ RFQ Justification Audit Record

| Field Name | Description | Data Source | Importance |
| --- | --- | --- | --- |
| Trade ID | Unique internal identifier for the transaction. | OMS/EMS | Critical (Primary Key) |
| Timestamp (RFQ Sent) | The exact time the RFQ was initiated and sent to counterparties. | EMS | Critical (Audit) |
| Instrument Identifier | ISIN, CUSIP, or other standard identifier for the financial instrument. | OMS | Critical (Context) |
| Order Details | Direction (Buy/Sell), quantity, and any specific client instructions. | OMS | Critical (Context) |
| System-Recommended CPs | List of counterparties suggested by the EMS based on the scoring matrix. | EMS Logic | High (Defensibility) |
| Selected CPs | The actual list of counterparties to whom the RFQ was sent. | Trader Input (EMS) | Critical (Evidence) |
| Deviation Rationale | Structured code or free-text reason if the selected list differs from the recommended list. | Trader Input (EMS) | Critical (Justification) |
| Quotes Received | A record of all quotes received, including price, quantity, and timestamp for each counterparty. | EMS | Critical (Evidence) |
| Winning Counterparty | The counterparty with whom the trade was executed. | EMS | Critical (Outcome) |
| Execution Timestamp | The exact time the winning quote was accepted. | EMS | Critical (Audit) |

## Phase 3 Post-Trade Analysis and Reporting

The documentation process does not end with the trade. The data captured must be used to refine the entire system. This is the domain of [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) and compliance oversight.

The primary activity in this phase is the regular, systematic review of execution quality. This involves aggregating the data from individual trade records to analyze counterparty performance over time. TCA reports should be generated that compare the performance of all counterparties against the relevant benchmarks. These reports are used to update the quantitative scores in the counterparty assessment matrix.

This creates a data-driven feedback loop, ensuring that the pre-trade recommendations are always based on the most current performance data. Furthermore, these aggregated reports form the basis of the firm’s [RTS 28](https://prime.greeks.live/area/rts-28/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) reporting, which requires firms to publish an annual summary of the top five execution venues and counterparties used for each class of financial instrument. The underlying justification records for each RFQ serve as the granular evidence supporting the aggregated data in these public reports.

## Calibrating the Execution Architecture

The accumulated documentation, the logs, the justification codes, and the performance reports represent more than a compliance archive. They form a vast dataset detailing the firm’s interaction with the market’s liquidity structure. The critical step is to view this dataset as a strategic asset, a proprietary source of intelligence for refining the firm’s execution architecture. How does the performance of your selected counterparties change under different volatility regimes?

Are there patterns in the deviation rationales provided by your traders that suggest a deficiency in the automated scoring model? Answering these questions transforms the documentation from a static record into a dynamic tool for systemic improvement.

## From Mandate to Mechanism

Ultimately, the MiFID II requirement should be seen as a catalyst. It provides the external impetus to build the internal mechanisms of control and analysis that are the hallmarks of a sophisticated trading operation. The process of documenting justification forces a firm to externalize its internal logic, to translate implicit knowledge into explicit rules and data.

In doing so, it creates a system that is not only defensible to regulators but is also more intelligent, more adaptable, and more aligned with the ultimate objective of delivering superior execution quality for clients. The true endpoint is an operational framework where compliance and performance optimization are two facets of the same integrated system.
