## Concept

The measurement of [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for Request for Quote (RFQ) transactions presents a unique set of analytical challenges. Unlike the continuous, anonymous flow of lit markets where a public tape provides a constant stream of reference prices, the RFQ protocol operates within a discreet, bilateral framework. An institution seeking liquidity initiates a targeted auction, soliciting prices from a select group of dealers. The subsequent transaction occurs off-book, its details known only to the involved parties.

This structural difference means that conventional [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) models, which are predicated on comparing executions to a continuous public benchmark like Volume-Weighted Average Price (VWAP), are fundamentally misaligned with the mechanics of the [RFQ process](https://prime.greeks.live/area/rfq-process/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Applying them directly produces a distorted picture of performance, failing to capture the true economic reality of the trade.

A meaningful analysis of RFQ execution quality requires a purpose-built system of measurement. This system must acknowledge the inherent nature of the protocol ▴ a series of private negotiations where the primary data points are the quotes received, not a public order book. The central objective shifts from measuring against a passive market average to evaluating the efficacy of the competitive auction itself.

The quality of execution is a direct function of the competitiveness of the dealer panel, the [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) associated with the request, and the final [execution price](https://prime.greeks.live/area/execution-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) relative to the full set of quotes received at a precise moment in time. Regulatory mandates, particularly under frameworks like MiFID II, have formalized the necessity of this deeper analysis, compelling institutions to demonstrate a robust process for achieving and verifying best execution across all trading protocols, including RFQs.

## The Bilateral Negotiation Impasse

The core of the [RFQ TCA](https://prime.greeks.live/area/rfq-tca/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) problem lies in establishing a fair and representative benchmark. In a lit market, the [arrival price](https://prime.greeks.live/area/arrival-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ▴ the mid-price at the moment a trade decision is made ▴ serves as a clean, objective starting point. For an RFQ, the concept of “arrival” is more complex. Is it the moment the trader decides to initiate the request?

Or the moment the quotes are received? The market can move significantly in the seconds or minutes between these events. A robust TCA model must account for this latency and measure performance against a benchmark that reflects the market state at the moment the dealer quotes are actually submitted. This requires a technological architecture capable of capturing high-frequency [market data](https://prime.greeks.live/area/market-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and time-stamping every event in the RFQ lifecycle with millisecond precision.

## Beyond the Winning Bid

A simplistic view of RFQ execution might only compare the winning price to the best price quoted. A more sophisticated analysis, however, understands that the entire set of received quotes constitutes a rich dataset. The spread between the best and worst quotes, the number of participating dealers, and the comparison of all quotes to the prevailing market mid-price provide deep insights into the health of the auction. A very wide spread might indicate a lack of dealer competition or high uncertainty, while a tight spread suggests a competitive and well-understood instrument.

The analysis must therefore extend beyond the single data point of the executed price to encompass the full context of the [private auction](https://prime.greeks.live/area/private-auction/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that produced it. This holistic view is the foundation of effective RFQ TCA.

> Effective RFQ TCA moves beyond simple price comparison to a comprehensive evaluation of the entire private auction process, from initial request to final settlement.

Ultimately, the goal is to build a system that provides actionable intelligence. It should identify which dealers consistently provide competitive quotes, quantify the market impact of signaling trading intent, and provide a clear, defensible record of [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This requires a departure from legacy TCA thinking and an embrace of a model specifically designed for the structure and dynamics of bilateral, [quote-driven markets](https://prime.greeks.live/area/quote-driven-markets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The subsequent sections will detail the strategic frameworks and operational protocols required to build and implement such a system.

## Strategy

Developing a strategic framework for RFQ [Transaction Cost](https://prime.greeks.live/area/transaction-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Analysis involves designing a multi-layered measurement system. This system must move from basic benchmarks to sophisticated, context-aware metrics that illuminate the subtle dynamics of quote-driven trading. The strategy is not merely about post-trade reporting; it is about creating a feedback loop that informs pre-trade decisions, optimizes counterparty selection, and provides a rigorous, evidence-based foundation for demonstrating best execution. A successful strategy rests on two pillars ▴ the selection of appropriate and progressively more insightful benchmarks, and the definition of [performance metrics](https://prime.greeks.live/area/performance-metrics/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that capture the unique characteristics of the RFQ process, such as information leakage and dealer behavior.

The initial step is to establish a hierarchy of benchmarks that provide a comprehensive view of execution costs. This hierarchy allows an institution to analyze performance from multiple perspectives, each benchmark telling a different part of the story. The choice of benchmarks should be deliberate, reflecting the firm’s trading philosophy and the specific characteristics of the assets being traded.

For instance, a firm trading highly liquid instruments might prioritize benchmarks that measure against the public market, while a firm trading illiquid credit may find peer universe analytics more relevant. The key is to create a flexible framework that can adapt to different market conditions and asset classes.

## A Hierarchy of Performance Benchmarks

A robust RFQ TCA strategy relies on a carefully selected set of benchmarks. Each one provides a different lens through which to view the transaction, and together they create a complete picture of execution quality. The following table outlines a hierarchy of common and advanced benchmarks, detailing their calculation and strategic utility.

| Benchmark Category | Specific Benchmark | Calculation Method | Strategic Insight Provided |
| --- | --- | --- | --- |
| Market-Relative | Arrival Price (Mid) | The mid-point of the National Best Bid and Offer (NBBO) or equivalent public market reference at the time the RFQ is initiated (T0). | Measures the total cost of the trading decision, including market movement during the quoting process (latency). |
| Market-Relative | Quote-Time Mid | The mid-point of the NBBO at the moment the winning quote is received from the dealer (T1). | Isolates the execution cost from the latency cost, focusing purely on the quality of the price relative to the concurrent public market. |
| Quote-Relative | Best Quoted Price | The most competitive price received from any dealer in the auction, whether executed or not. | Measures the ability to execute at the best possible level offered within the private auction. A consistent shortfall may indicate issues with the “winner’s curse.” |
| Quote-Relative | Average Quoted Price | The average of all quotes received from all participating dealers for a given RFQ. | Provides a measure of the central tendency of the auction, helping to identify outlier quotes and assess the overall competitiveness of the dealer panel. |
| Peer-Relative | Peer Universe Analytics | Comparison of execution costs for similar trades (size, asset, time of day) against an anonymized pool of data from other institutions. | Offers a powerful external validation of performance, answering the question ▴ “How did my execution compare to what others achieved in the market?” |

## Defining Core Performance Metrics

With a benchmark framework in place, the next step is to define the specific metrics that will be used to evaluate performance. These metrics must go beyond simple slippage calculations to capture the nuances of the RFQ workflow. A comprehensive TCA strategy will incorporate a variety of metrics designed to answer specific questions about the trading process.

- **[Implementation Shortfall](https://prime.greeks.live/area/implementation-shortfall/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ This foundational metric calculates the total cost of the trade relative to the arrival price at the time the decision to trade was made. It is calculated as (Execution Price – Arrival Price) / Arrival Price, and it captures both the market impact of the trade and the opportunity cost incurred due to any delay in execution. 

- **[Spread Capture](https://prime.greeks.live/area/spread-capture/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ This metric measures how much of the bid-ask spread the trader was able to capture. It is particularly relevant for liquidity-providing trades. It is calculated by comparing the execution price to the market mid-point at the time of the trade. A positive value indicates that the trade was executed at a price better than the mid. 

- **Information Leakage / Reversion** ▴ This is a critical metric for RFQs. It measures the tendency of the market to move away from the trade direction immediately after execution. A high level of adverse reversion (the market moving against the trader post-trade) can signal that the RFQ itself alerted the market to the trading intention, leading to front-running or other predatory behavior. It is typically measured by comparing the execution price to the market mid-point at various intervals (e.g. 1 minute, 5 minutes, 15 minutes) after the trade. 

- **[Dealer Performance](https://prime.greeks.live/area/dealer-performance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Scorecarding** ▴ This involves tracking the performance of individual liquidity providers over time. Key metrics include the dealer’s hit rate (the percentage of times their quote is selected), the average slippage of their quotes relative to the best quote, and their post-trade reversion statistics. This data is vital for optimizing the [dealer panel](https://prime.greeks.live/area/dealer-panel/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). 

> A successful TCA strategy for RFQs combines a multi-layered benchmark framework with specific performance metrics to create a comprehensive and actionable view of execution quality.

By implementing this strategic framework, an institution can transform its RFQ TCA from a simple compliance exercise into a powerful tool for performance optimization. It provides the data necessary to refine trading strategies, manage counterparty relationships more effectively, and ultimately, reduce implicit trading costs. The next section will detail the operational steps and technological infrastructure required to execute this strategy.

## Execution

The operational execution of a post-trade TCA model for RFQs is a data-intensive process that demands a high degree of precision and a robust technological infrastructure. It involves the systematic capture, normalization, and analysis of a wide range of data points associated with each RFQ event. The objective is to move from the strategic framework outlined previously to a tangible, repeatable process that generates the reports and insights needed to drive decision-making. This process can be broken down into several key stages ▴ data capture and integration, analytical processing, and report generation and review.

Success in this endeavor hinges on the quality and granularity of the data collected. Every step of the RFQ lifecycle, from the initial decision to trade to the final settlement, must be time-stamped and recorded. This requires seamless integration between the firm’s Order Management System (OMS) or Execution Management System (EMS), its market data feeds, and the TCA platform itself.

Without this foundational data layer, any subsequent analysis will be incomplete and potentially misleading. As outlined in procurement requests by sophisticated institutions, the system must be capable of processing this data on a T+1 basis to provide timely feedback to the trading desk.

## The Data Capture Protocol

To effectively analyze RFQ transactions, a specific set of data points must be captured for every request. This goes far beyond a simple execution record. The following list details the essential data elements required for a comprehensive RFQ TCA program.

- **RFQ Initiation Data** ▴ This includes the unique RFQ ID, the instrument identifier (e.g. CUSIP, ISIN), the side (buy/sell), the requested quantity, and the precise timestamp (to the millisecond) when the RFQ was sent out from the trader’s system. 

- **Counterparty Data** ▴ A list of all dealers to whom the RFQ was sent. This is crucial for tracking participation rates and identifying which dealers are being over- or under-utilized. 

- **Quote Response Data** ▴ For each dealer that responds, the system must capture their name, the quoted price, the quoted quantity (which may differ from the requested quantity), and the precise timestamp of when the quote was received. It is critical to capture data for all responding dealers, not just the winner. 

- **Execution Data** ▴ The name of the winning dealer, the final execution price, the executed quantity, and the timestamp of the execution message. 

- **Market Data Snapshots** ▴ For each key timestamp (RFQ initiation, quote receipt, execution), the system must capture a snapshot of the relevant market data. This includes the National Best Bid and Offer (NBBO), the last trade price, and recent trading volumes. For [fixed income](https://prime.greeks.live/area/fixed-income/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), this might be a composite price from a data provider.

## The Analytical Engine in Practice

Once the data is captured, the analytical engine processes it to calculate the key performance metrics. The following table provides a simplified example of a post-trade TCA report for a single RFQ transaction, illustrating how the raw data is transformed into actionable insights.

| Metric | Value / Calculation | Interpretation |
| --- | --- | --- |
| Trade Details | Buy 100,000 shares of XYZ Corp | The parameters of the order. |
| Arrival Price (T0) | $50.05 (Mid-price at 10:00:00.000) | The market price when the decision to trade was made. |
| Quotes Received | Dealer A ▴ $50.08, Dealer B ▴ $50.07, Dealer C ▴ $50.09 | The competitive landscape of the private auction. |
| Winning Quote | $50.07 from Dealer B (Received at 10:00:03.500) | The best price secured through the RFQ process. |
| Quote-Time Mid (T1) | $50.06 (Mid-price at 10:00:03.500) | The market price at the moment of execution, isolating latency. |
| Implementation Shortfall | 2 basis points (($50.07 – $50.05) / $50.05) | The total cost of the trade, including market movement during the 3.5-second quoting window. |
| Slippage vs. Quote-Time Mid | 1 basis point (($50.07 – $50.06) / $50.06) | The “pure” execution cost, showing the price was slightly higher than the concurrent market mid. |
| Slippage vs. Best Quote | 0 basis points | The trader successfully executed at the best price offered by the panel. |
| Post-Trade Reversion (1 min) | -$0.02 (Market mid moved to $50.04) | A negative reversion, indicating the market moved in the trader’s favor post-trade. This suggests low information leakage. |

## From Single Trade to Systemic Insight

While analyzing a single trade is useful, the true power of RFQ TCA comes from aggregating this data over time to identify trends and patterns. This is where dealer performance scorecards become invaluable. By tracking metrics across hundreds or thousands of RFQs, an institution can build a detailed, quantitative profile of each liquidity provider. This enables a data-driven approach to managing counterparty relationships.

> Aggregated TCA data transforms anecdotal evidence about dealer performance into a quantitative, defensible basis for optimizing counterparty selection and trading strategy.

The table below illustrates a hypothetical quarterly dealer scorecard, providing the kind of systemic insight that a robust TCA process can deliver. This type of analysis allows a firm to move beyond just hit rates and understand the true quality of the liquidity each dealer provides. It can reveal, for instance, a dealer who wins many quotes but consistently shows high, adverse post-trade reversion, suggesting their pricing may be aggressive but carries a high signaling risk. Armed with this information, a trading desk can refine its dealer panel, adjust its routing logic, and engage in more productive, data-backed conversations with its liquidity providers to improve overall execution quality.

## Quarterly Dealer Performance Scorecard ▴ Q3 2025

| Dealer | RFQs Received | Response Rate | Hit Rate | Avg. Slippage vs. Best Quote (bps) | Avg. 1-Min Reversion (bps) |
| --- | --- | --- | --- | --- | --- |
| Dealer A | 500 | 95% | 25% | 0.10 | -0.5 |
| Dealer B | 480 | 98% | 35% | 0.05 | -0.2 |
| Dealer C | 350 | 90% | 15% | 0.25 | 1.5 |
| Dealer D | 510 | 85% | 25% | 0.15 | -0.8 |

## From Measurement to Intelligence

The implementation of a sophisticated post-trade TCA model for RFQs marks a significant evolution in an institution’s operational capabilities. It transforms the measurement of execution quality from a retrospective, compliance-driven exercise into a dynamic, forward-looking source of strategic intelligence. The system described ceases to be a simple reporting tool and becomes an integral part of the firm’s learning architecture. The data it generates provides a clear, unbiased mirror reflecting the effectiveness of the firm’s liquidity sourcing strategy, the behavior of its counterparties, and the subtle costs embedded in its trading workflow.

This analytical framework allows for a deeper, more nuanced dialogue with liquidity providers, one grounded in objective data rather than subjective perception. It provides the foundation for optimizing the entire RFQ process, from deciding which dealers to include in an auction to refining the timing and sizing of requests to minimize market footprint. The ultimate value of such a system lies in its ability to make the implicit costs of trading explicit. By quantifying concepts like information leakage and the winner’s curse, it empowers a firm to take control of its execution outcomes, fostering a culture of continuous improvement and providing a demonstrable, competitive edge in the marketplace.
