## Concept

Quantitatively proving best execution for illiquid assets traded via a [Request for Quote](https://prime.greeks.live/area/request-for-quote/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (RFQ) protocol is an exercise in architectural integrity. The challenge arises because these instruments exist outside the universe of continuous, transparent price feeds that underpin conventional [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA). For assets like thinly traded corporate bonds, bespoke derivatives, or large blocks of equities, there is no consolidated tape to provide a definitive reference price.

The act of seeking a price through an RFQ itself introduces a signal into the market, a signal that can move the price before a transaction even occurs. Therefore, the traditional model of comparing an execution price to a universal benchmark is fundamentally flawed in this context.

The solution requires a shift in perspective. Instead of seeking a single, external point of truth, a firm must construct an internal, auditable system of record that captures the entire lifecycle of the trade. This system becomes the evidence. The proof of [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is derived from the quality and completeness of the data collected and the rigor of the process followed.

It is a demonstration that, given the available information and market conditions at a specific moment, the firm made a reasonable and defensible decision. This moves the focus from a simple price comparison to a holistic evaluation of the execution process itself.

At its core, this is a data architecture problem. A firm must build a framework capable of time-stamping and logging every critical decision point, from the portfolio manager’s initial intent to the final settlement. This includes documenting the rationale for the trade, the prevailing market color, the selection of counterparties for the RFQ, the responses received, and the logic for choosing the winning bid. The [quantitative proof](https://prime.greeks.live/area/quantitative-proof/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) emerges from analyzing this rich, internally generated dataset to demonstrate a consistent, disciplined, and unbiased approach to sourcing liquidity and achieving favorable terms for the end investor.

## Strategy

A robust strategy for demonstrating best execution in the illiquid RFQ space rests on a multi-layered framework that encompasses pre-trade, in-flight, and [post-trade analysis](https://prime.greeks.live/area/post-trade-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This structure ensures that every stage of the transaction is documented and justifiable, creating a comprehensive audit trail that stands up to regulatory scrutiny. The objective is to build a narrative supported by data, showing that the final execution was the result of a deliberate and intelligent process designed to optimize outcomes for the client.

## A Multi-Layered Analytical Framework

The strategic approach can be broken down into three distinct, yet interconnected, phases of analysis. Each phase generates critical data points that collectively form the body of evidence for best execution.

![A dark, glossy sphere atop a multi-layered base symbolizes a core intelligence layer for institutional RFQ protocols. This structure depicts high-fidelity execution of digital asset derivatives, including Bitcoin options, within a prime brokerage framework, enabling optimal price discovery and systemic risk mitigation](https://options.greeks.live/wp-content/uploads/2025/07/institutional-rfq-protocol-architecture-for-digital-asset-derivatives.jpg)

## Layer 1 Pre Trade Intelligence

This initial phase is concerned with capturing the context and intent behind the trade before any market action is taken. It is about documenting the “why” and the “what” of the order. Key activities in this layer include:

- **Defining Liquidity Profiles** ▴ Assets are categorized into liquidity buckets (e.g. Tier 1 for highly liquid, Tier 3 for highly illiquid). This classification dictates the appropriate execution strategy and the number of counterparties to include in an RFQ.

- **Documenting Portfolio Manager Intent** ▴ The system must capture the portfolio manager’s rationale for the trade. Is it a strategic rebalancing, a response to a credit event, or a need to raise cash? This context is vital for judging the execution’s success against the order’s specific goals.

- **Capturing Market Conditions** ▴ A snapshot of the market environment at the time of the order is essential. This includes relevant index levels, volatility measures, recent news, and any available pre-trade pricing indications or axes from dealers.

## Layer 2 in Flight Execution Management

This layer focuses on the [RFQ process](https://prime.greeks.live/area/rfq-process/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) itself, ensuring it is conducted in a fair, competitive, and controlled manner. The goal is to prove that the firm took reasonable steps to solicit competitive quotes while minimizing information leakage. Key components are:

- **Systematic Counterparty Selection** ▴ The choice of dealers to include in the RFQ must be data-driven. A counterparty matrix, based on historical performance, response rates, and pricing competitiveness for similar assets, provides a defensible basis for selection.

- **Process Automation and Logging** ▴ The RFQ process should be managed electronically to the greatest extent possible. This ensures that all communications, timestamps, quotes, and decisions are automatically logged, creating an immutable record of the auction.

- **Minimizing Market Impact** ▴ For particularly large or sensitive trades, the strategy may involve a staged RFQ process or using a “Request for Quote to One” (RFQ-to-1) protocol where a trade is negotiated off-venue and then consummated on-venue for reporting and compliance purposes.

> A defensible best execution strategy for illiquid assets is built on a foundation of systematic data capture at every stage of the trade lifecycle.

## Layer 3 Post Trade Quantitative Analysis

This is the final and most quantitative layer, where the executed trade is analyzed against relevant benchmarks to measure its quality. Given the absence of a single reference price, this involves creating and comparing against a composite of data points.

The table below outlines several benchmarking methodologies that can be employed in post-trade analysis for illiquid RFQ trades.

### Table 1 ▴ Post-Trade Benchmarking Methodologies for Illiquid Assets

| Benchmark Type | Description | Advantages | Challenges |
| --- | --- | --- | --- |
| Arrival Price | The price of the asset or a comparable proxy at the moment the order is received by the trading desk. For illiquid assets, this is often a calculated price from a pricing service or a recent trade. | Provides a clear starting point for measuring execution cost (slippage). | The “arrival price” itself may be stale or theoretical for assets that trade infrequently. |
| Peer Group Analysis | The executed price is compared to the other quotes received during the RFQ process. Key metrics include spread to the mean or median quote. | Uses actual, firm quotes received at the time of the trade, reflecting real-world liquidity. | Effectiveness depends on the competitiveness of the dealer group. A narrow set of quotes may not represent the full market. |
| Synthetic Benchmark Pricing | A benchmark price is constructed using a model based on more liquid, correlated assets. For a corporate bond, this could involve using a government bond yield plus a credit spread derived from a credit default swap (CDS) index or a basket of similar bonds. | Creates a dynamic, market-sensitive benchmark even when the asset itself is not trading. | The model’s accuracy is dependent on the quality of the inputs and the stability of the correlation between the asset and its proxies. Requires significant quantitative expertise. |
| Historical Price Analysis | The execution price is compared to recent trades in the same or very similar instruments. | Based on actual transaction data. | Past prices may be irrelevant in a changed market environment. “Similar” instruments may have important idiosyncratic differences. |

By combining these layers, a firm can move beyond a simple price check and build a comprehensive, process-oriented case for best execution. The strategy is to demonstrate diligence, fairness, and quantitative rigor at every step, creating a defensible framework that protects both the firm and its clients.

## Execution

The execution of a defensible best execution framework for [illiquid assets](https://prime.greeks.live/area/illiquid-assets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a deeply operational and technical undertaking. It requires the integration of policy, procedure, and technology to create a seamless and auditable system. This system must translate the strategic principles of pre-trade, in-flight, and post-trade analysis into a concrete, repeatable workflow that traders can follow and compliance officers can verify. The ultimate goal is to produce a quantitative, evidence-based record for every single illiquid RFQ transaction.

## The Operational Playbook

Implementing this framework requires a detailed [operational playbook](https://prime.greeks.live/area/operational-playbook/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This playbook serves as a step-by-step guide for all stakeholders, ensuring consistency and completeness in the execution process. It is a living document that should be reviewed and refined regularly by a [best execution committee](https://prime.greeks.live/area/best-execution-committee/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

- **Trade Inception and Pre-Trade Documentation** ▴ 

<li>The process begins when a portfolio manager (PM) creates an order in the Order Management System (OMS).

- The OMS must have mandatory fields for the PM to input the trade rationale and to confirm the asset’s liquidity classification.

- The system automatically captures a pre-trade snapshot of relevant market data, including levels of correlated assets and indices, at the moment the order is passed to the trading desk.

</li>
- **Counterparty Selection and RFQ Construction** ▴ 

<li>The trader receives the order in the Execution Management System (EMS).

- Based on the asset’s liquidity profile, the firm’s policy will dictate a minimum number of counterparties for the RFQ (e.g. 3 for Tier 2 illiquid, 5 for Tier 1).

- The trader consults a system-generated [counterparty performance matrix](https://prime.greeks.live/area/counterparty-performance-matrix/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to select the most appropriate dealers. The selection must be justifiable based on historical data.

</li>
- **Electronic RFQ Execution** ▴ 

<li>The RFQ is launched electronically through the EMS, which is integrated with a multi-dealer RFQ platform.

- The system logs the exact time the request is sent to each dealer and the precise time each response is received. All quotes are captured and stored in a centralized database.

</li>
- **Execution Decision and Justification** ▴ 

<li>The trader executes the trade with one of the responding dealers.

- If the winning quote is not the best price received (e.g. a better price was quoted but for a smaller size), the trader must provide a documented justification within the EMS. This creates a crucial audit point.

</li>
- **Post-Trade Analysis and Exception Reporting** ▴ 

<li>Upon execution, the trade data flows automatically to a TCA system.

- The system calculates the [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) metrics against the pre-defined benchmarks (e.g. arrival price, [synthetic benchmark](https://prime.greeks.live/area/synthetic-benchmark/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)).

- Any trade that breaches a pre-set tolerance level (e.g. slippage greater than X basis points) is automatically flagged as an “exception” and routed for review.

</li>
- **Committee Review and Governance** ▴ 

<li>The firm’s best execution committee meets on a regular basis (e.g. quarterly) to review the aggregate TCA data, [counterparty performance](https://prime.greeks.live/area/counterparty-performance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and all exception reports.

- The committee is responsible for updating the operational playbook, refining counterparty lists, and ensuring the overall framework remains effective.

</li>

## Quantitative Modeling and Data Analysis

The credibility of the entire framework hinges on the robustness of its quantitative models and data analysis. This is where the “proof” is forged. The analysis must be sophisticated enough to handle the complexity of illiquid markets while remaining clear enough to be understood by regulators and clients.

> The core of quantitative proof lies in transforming episodic, off-book quotes into a structured dataset for systematic analysis.

A primary tool in this process is the [Execution Quality Scorecard](https://prime.greeks.live/area/execution-quality-scorecard/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This scorecard synthesizes multiple data points from the [trade lifecycle](https://prime.greeks.live/area/trade-lifecycle/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) into a single, comprehensive view of a transaction’s quality. It provides a standardized format for evaluating every trade.

### Table 2 ▴ RFQ Execution Quality Scorecard

| Metric | Definition | Example Data Point | Contribution to Proof |
| --- | --- | --- | --- |
| Trade ID | Unique identifier for the transaction. | T-12345 | Ensures traceability and auditability. |
| Asset Liquidity Tier | Pre-defined liquidity classification (1-3). | Tier 2 | Sets the context for the execution challenge and the expected standards. |
| Synthetic Benchmark Price | Model-derived price at the time of execution. | $101.50 | Provides a dynamic, market-sensitive reference price independent of the RFQ process itself. |
| Executed Price | The actual price at which the trade was done. | $101.45 | The primary data point for analysis. |
| Slippage vs. Benchmark (bps) | (Executed Price – Benchmark Price) / Benchmark Price. | -4.9 bps | The key measure of price performance. Negative slippage indicates price improvement. |
| Number of Dealers Queried | Total counterparties included in the RFQ. | 5 | Demonstrates the effort to create a competitive pricing environment. |
| Number of Responses | Total counterparties that provided a quote. | 4 | Indicates the level of market interest and available liquidity. |
| Price Improvement vs. Mean Quote (bps) | (Mean of all quotes – Executed Price) / Mean of all quotes. | +2.1 bps | Measures the quality of the execution relative to the available peer group liquidity. |

Alongside individual trade analysis, aggregating this data provides powerful insights into counterparty performance. A Counterparty Performance Matrix is essential for fulfilling the data-driven dealer selection requirement of the playbook.

## How Can a Firm Validate Counterparty Effectiveness?

A firm validates counterparty effectiveness by systematically tracking and analyzing performance across a range of quantitative metrics. This data-driven approach removes subjectivity from the selection process and creates a virtuous cycle where better-performing dealers are rewarded with more flow. The matrix below illustrates how this data can be structured.

### Table 3 ▴ Quarterly Counterparty Performance Matrix – Illiquid Bonds

| Counterparty | RFQs Received | Response Rate | Win Rate | Avg. Price Improvement (bps) | Overall Score |
| --- | --- | --- | --- | --- | --- |
| Dealer A | 150 | 95% | 20% | +1.5 | 8.5/10 |
| Dealer B | 145 | 80% | 15% | -0.5 | 6.0/10 |
| Dealer C | 120 | 98% | 35% | +2.8 | 9.5/10 |
| Dealer D | 80 | 75% | 10% | +0.2 | 5.5/10 |

## Predictive Scenario Analysis

To illustrate the system in action, consider a realistic case study. A portfolio manager at an institutional asset manager needs to sell a $25 million block of an 8-year, non-callable corporate bond issued by a mid-cap industrial company. The bond is classified as a Tier 2 illiquid asset. The PM enters the order into the OMS, noting the rationale as “reducing single-issuer concentration risk ahead of earnings.” The system automatically logs the time and captures the current level of the CDX Investment Grade index and the yields on 7-year and 10-year U.S. Treasury bonds.

The order arrives at the trading desk. The trader, following the playbook, knows a Tier 2 asset requires a minimum of five dealers in the RFQ. Consulting the Counterparty Performance Matrix, the trader selects Dealer C (top performer), Dealer A (high response rate), Dealer B (incumbent market maker in the sector), and two other regional dealers known for activity in industrial credits. The selection rationale is noted in the EMS.

At 10:05:00 AM, the trader launches the electronic RFQ. The system dashboard updates in real-time:

- 10:05:35 AM ▴ Dealer A responds with a bid of 100.25.

- 10:06:10 AM ▴ Dealer B responds with a bid of 100.22.

- 10:06:45 AM ▴ One regional dealer declines to quote.

- 10:07:15 AM ▴ Dealer C responds with a bid of 100.32.

- 10:07:30 AM ▴ The second regional dealer responds with a bid of 100.28.

The trader has a clear best bid from Dealer C. The trader executes the full $25 million block with Dealer C at 100.32. The execution is time-stamped at 10:07:50 AM.

Immediately, the post-trade analytics engine gets to work. It had calculated a synthetic [benchmark price](https://prime.greeks.live/area/benchmark-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) of 100.30 at the moment of execution, based on the Treasury yields and the prevailing credit spread for similar industrial bonds. The system generates the Execution Quality Scorecard. The slippage is calculated as +2 basis points against the synthetic benchmark, indicating a favorable execution.

The [price improvement](https://prime.greeks.live/area/price-improvement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) versus the mean quote of all four responses (100.2675) is over 5 basis points. The entire process, from order inception to post-trade analysis, is documented with over a dozen timestamps and data points, forming a complete, auditable record. When the best execution committee meets, this trade will appear as a successful example of the framework in action, proving that a disciplined, data-driven process led to a superior outcome for the end investor.

## System Integration and Technological Architecture

The successful execution of this playbook is impossible without a well-designed technological architecture. The various systems used in the trade lifecycle must communicate with each other seamlessly to ensure data integrity and process automation. The architecture is the backbone of the quantitative proof.

The data must flow logically from one system to the next:

- **Order Management System (OMS)** ▴ The source of the order and the PM’s intent. It must be able to pass detailed order information, including custom tags for rationale, to the EMS.

- **Execution Management System (EMS)** ▴ The trader’s cockpit. It must integrate with RFQ platforms via APIs and be capable of both sending orders and receiving rich execution data back. It is the central point for logging trader actions and decisions.

- **RFQ Platforms** ▴ These external venues (e.g. Tradeweb, MarketAxess) are where the price discovery happens. Critical data to be captured via their APIs includes dealer identities, quote times, quote prices, and declination messages.

- **Data Warehouse** ▴ A centralized, time-series database is the heart of the system. It ingests and stores all the data from the OMS, EMS, and RFQ platforms, creating a single source of truth for every transaction.

- **Analytics Engine** ▴ This component, which could be a dedicated vendor solution or an in-house system using Python or R libraries, queries the data warehouse to perform the TCA, generate the scorecards, and update the counterparty performance matrices.

A critical element of this integration is the Financial Information eXchange (FIX) protocol, the standard language for electronic trading. Specific FIX tags are essential for capturing the necessary data with precision.

- ** ClOrdID (Tag 11) ** ▴ The unique order ID that links the entire process back to the original PM instruction.

- ** TransactTime (Tag 60) ** ▴ The timestamp for every event, from order creation to execution, providing the temporal backbone of the audit trail.

- ** QuoteReqID (Tag 131) ** ▴ The unique ID for the RFQ sent to dealers.

- ** QuoteID (Tag 117) ** ▴ The unique ID for each quote received back from a dealer.

- ** Price (Tag 44) and OrderQty (Tag 38) ** ▴ The core components of the quote and the final execution.

By building an architecture that systematically captures these data points, a firm creates a powerful evidentiary record. The quantitative proof of best execution for illiquid assets is not found in a single number but in the design and operation of the entire system. It is the architecture itself that provides the defense.

## Is Your Execution Framework an Asset or a Liability?

The framework detailed here provides a pathway to quantitatively proving best execution for the most challenging assets. It transforms a regulatory burden into a system of intelligence. The data generated does more than satisfy compliance; it illuminates counterparty behavior, reveals hidden liquidity pockets, and provides a feedback loop for continuously improving trading strategy. The process of building this system forces a firm to confront fundamental questions about its own operational integrity and technological capabilities.

Ultimately, the ability to prove best execution is a reflection of the firm’s core architecture. A fragmented, manual process will always struggle to produce a coherent defense, leaving the firm exposed to regulatory risk and client dissatisfaction. A fully integrated, automated, and data-centric framework, however, becomes a strategic asset.

It provides not only proof for the past but also a predictive edge for the future, enabling traders to make smarter, faster, and more defensible decisions. The question every firm must ask is whether its current system is merely a record of events or an active driver of superior performance.
