## Concept

The reliance on a simple midpoint of a bid and ask spread as a universal benchmark for [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a foundational error in [market microstructure](https://prime.greeks.live/area/market-microstructure/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), particularly within the domain of illiquid Request for Quote (RFQ) systems. This practice, born from the transparent, high-frequency world of liquid equities, fails to account for the defining characteristics of illiquid assets. The core of the issue resides in the informational dynamics and structural realities of markets where continuous price discovery is absent. An RFQ for an illiquid instrument is a search for a price in a market defined by its opacity.

The midpoint of a spread, in this context, represents a phantom calculation. It is an arithmetic convenience derived from quotes that are often stale, indicative, or strategically skewed to protect the market maker from the very real threat of [adverse selection](https://prime.greeks.live/area/adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

In a liquid market, the bid and ask prices are tightly clustered around a generally accepted fundamental value, and the midpoint serves as a reasonable proxy for this value. The constant flow of trades provides a gravitational pull that keeps quotes honest and reflective of current supply and demand. [Illiquid markets](https://prime.greeks.live/area/illiquid-markets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) operate under a different set of physical laws. Here, the last traded price may be hours, days, or even weeks old.

The bid and ask quotes displayed on a screen, if they exist at all, are frequently wide and carry little firm commitment. They are invitations to negotiate, not firm prices for immediate execution. To treat their midpoint as a true measure of value is to build a system on a foundation of sand. The price of an [illiquid asset](https://prime.greeks.live/area/illiquid-asset/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a negotiated outcome, a unique data point created at the moment of a specific transaction between two parties, each with their own private information and motivations.

> A simple midpoint in an illiquid RFQ is a calculated guess in a market that penalizes guessing.

The process of an RFQ for an illiquid asset is a delicate dance of information revelation. The initiator of the RFQ is signaling a need to trade, a piece of information that has value. The responders, typically [market makers](https://prime.greeks.live/area/market-makers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), are attempting to price the asset while simultaneously pricing the risk that the initiator knows something they do not. This is the essence of adverse selection.

The seller of an obscure [corporate bond](https://prime.greeks.live/area/corporate-bond/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) may be selling because they have private information about the issuer’s deteriorating creditworthiness. The buyer of a complex, bespoke derivative may have a unique hedging need that makes the instrument more valuable to them than to anyone else. In such an environment, a market maker’s quote is a defensive mechanism. It is priced to protect them from being “picked off” by a better-informed counterparty. The midpoint of such defensive quotes will systematically diverge from the asset’s true, albeit unobservable, value.

## The Illusion of the Stable Midpoint

The concept of a stable, reliable midpoint is a construct of liquid, transparent markets. In these environments, high-frequency trading and a deep order book ensure that the bid and ask prices are constantly updated, reflecting the latest information and order flow. The midpoint, therefore, is a dynamic and reasonably accurate representation of the current market consensus on value. This breaks down completely in the context of [illiquid assets](https://prime.greeks.live/area/illiquid-assets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for several structural reasons:

- **Stale and Indicative Quotes** ▴ The quotes that form the basis of a midpoint calculation for an illiquid asset are often not firm. They may be indicative quotes from a dealer’s inventory sheet, updated infrequently. Using such quotes to calculate a midpoint creates a benchmark that is out of touch with the asset’s true market value at the time of the RFQ.

- **Price Discreteness** ▴ The minimum price increment, or tick size, can have a significant impact on the midpoint’s reliability. In markets for low-priced assets, the tick size can be a large percentage of the asset’s value. This forces market makers to set quotes asymmetrically around the fundamental value, leading to a biased midpoint. Research has shown that this bias can be substantial, overstating the effective spread by a significant margin.

- **Absence of Continuous Trading** ▴ Without a constant stream of trades to anchor prices, the concept of a “current” market price is nebulous. The last traded price could be from a different market regime entirely. The midpoint of a wide, indicative spread in such a situation is a poor guide to the price at which a trade can actually be executed.

## Adverse Selection and the Winner’s Curse

The primary reason a [simple midpoint](https://prime.greeks.live/question/what-are-the-primary-risks-associated-with-execution-in-a-midpoint-dark-pool/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) fails as a benchmark for illiquid RFQs is the pervasive influence of adverse selection. Adverse selection arises from [information asymmetry](https://prime.greeks.live/area/information-asymmetry/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ▴ one party in a transaction has more or better information than the other. In illiquid markets, the party initiating the RFQ is often assumed to be the better-informed party. This creates a challenging environment for the market makers responding to the RFQ.

Consider a portfolio manager looking to sell a large block of an unrated, privately placed bond. They may be selling because their internal analysis suggests the issuer’s credit quality is about to be downgraded. When they send out an RFQ to a group of dealers, those dealers are immediately on high alert. They know that the seller may have a compelling, non-public reason to sell.

To protect themselves, the dealers will widen their bid-ask spreads, lowering the price they are willing to pay for the bond. The midpoint of these defensive quotes will be artificially low, reflecting the dealers’ risk aversion rather than the bond’s fundamental value.

This leads to a phenomenon known as the “winner’s curse.” The dealer who “wins” the RFQ by offering the highest bid price may have done so because they were the least informed or the most aggressive in their pricing. They have “won” the right to buy an asset that the seller was eager to get rid of, potentially at a price that is too high. A benchmark based on the midpoint of the [quotes received](https://prime.greeks.live/question/how-are-quotes-submitted-in-an-rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in such a scenario would be deeply flawed. It would suggest that the winning bid was close to the “fair” market price, when in reality, the entire quoting process was skewed by information asymmetry.

## How Does Information Asymmetry Manifest in RFQs?

The impact of information asymmetry is not uniform across all [illiquid RFQs](https://prime.greeks.live/area/illiquid-rfqs/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). It is a function of several variables, including the size of the trade, the complexity of the instrument, and the reputation of the counterparties. A large trade in a complex, opaque instrument from a well-informed hedge fund will be treated with far more caution by market makers than a small trade in a more standardized instrument from a less sophisticated client.

A robust [TCA system](https://prime.greeks.live/area/tca-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) must be able to account for these factors. A [simple midpoint benchmark](https://prime.greeks.live/question/what-is-the-difference-between-a-vwap-benchmark-and-an-arrival-price-benchmark-in-tca/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a blunt instrument, incapable of capturing the nuances of these information-rich interactions.

## Strategy

Moving beyond a simple midpoint benchmark for illiquid RFQs requires a strategic shift in how we think about [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The goal is to move from a static, one-size-fits-all approach to a dynamic, context-aware framework that acknowledges the unique characteristics of illiquid markets. This involves developing more sophisticated benchmarks, implementing strategies to mitigate [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and adopting a more holistic view of execution quality that goes beyond just the price of the trade.

The central pillar of this strategic shift is the recognition that in illiquid markets, the [RFQ process](https://prime.greeks.live/area/rfq-process/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is as much about information discovery as it is about price discovery. The quotes received from market makers are not just prices; they are signals. They contain information about the market makers’ inventory, their risk appetite, and their perception of the initiator’s motives.

A sophisticated trading desk will analyze these signals to build a more complete picture of the market for a particular asset at a particular point in time. This “market intelligence” is then used to inform the trading decision, whether it’s to execute the trade, to hold off, or to revise the trading strategy.

> A superior benchmark for an illiquid RFQ is one that adapts to the information revealed during the quoting process itself.

This adaptive approach stands in stark contrast to the traditional method of simply comparing the executed price to the pre-trade midpoint. A pre-trade midpoint is a snapshot of a market that is often stale and unrepresentative. A more effective strategy is to use a benchmark that evolves as new information becomes available. This could be a volume-weighted average price (VWAP) of the quotes received, a regression-based benchmark that adjusts for the characteristics of the asset and the [market conditions](https://prime.greeks.live/area/market-conditions/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), or even a qualitative assessment of the quoting process itself.

## Alternative Benchmarking Frameworks

Developing robust alternatives to the simple [midpoint benchmark](https://prime.greeks.live/question/what-is-the-difference-between-a-vwap-benchmark-and-an-arrival-price-benchmark-in-tca/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is the cornerstone of an effective TCA strategy for illiquid RFQs. These alternatives fall into several broad categories, each with its own strengths and weaknesses.

- **[Regression-Based Benchmarks](https://prime.greeks.live/area/regression-based-benchmarks/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ This approach involves building a statistical model that predicts the “fair” price of an asset based on its characteristics (e.g. [credit rating](https://prime.greeks.live/area/credit-rating/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), maturity, coupon for a bond) and the prevailing market conditions (e.g. interest rates, credit spreads). The executed price is then compared to the model’s prediction. This method is particularly useful for assets that are part of a larger, more liquid asset class, where a reliable pricing model can be built.

- **[Peer Group Analysis](https://prime.greeks.live/area/peer-group-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ For assets that are truly unique and have no close comparables, a peer group analysis can be a useful tool. This involves identifying a group of similar assets that have traded recently and using their trading prices to establish a benchmark. The challenge with this approach is defining the peer group. What makes one bond “similar” to another? The criteria must be carefully chosen to ensure that the comparison is meaningful.

- **[Quote-Driven Benchmarks](https://prime.greeks.live/area/quote-driven-benchmarks/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ Instead of relying on a pre-trade midpoint, a quote-driven benchmark uses the quotes received during the RFQ process to construct a more dynamic and relevant benchmark. This could be the volume-weighted average price (VWAP) of the quotes, the median quote, or a more sophisticated measure that gives more weight to the quotes from dealers who are known to be active market makers in that particular asset.

The choice of benchmark will depend on the specific asset being traded and the available data. There is no single “best” benchmark for all illiquid RFQs. The key is to have a flexible and adaptable framework that can be tailored to the specific circumstances of each trade.

The following table provides a high-level comparison of these [alternative benchmarking frameworks](https://prime.greeks.live/question/what-are-the-primary-differences-in-benchmarking-rfq-trades-versus-central-limit-order-book-trades/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite):

### Comparison of Alternative Benchmarking Frameworks

| Benchmark Framework | Description | Strengths | Weaknesses |
| --- | --- | --- | --- |
| Regression-Based | Uses a statistical model to predict a fair price based on asset characteristics and market conditions. | Objective and data-driven; can be applied to a wide range of assets. | Model-dependent; requires a large amount of historical data to build a reliable model. |
| Peer Group Analysis | Compares the traded price to the prices of similar assets that have traded recently. | Intuitive and easy to understand; useful for unique assets with no direct comparables. | Subjective in defining the peer group; can be difficult to find truly comparable assets. |
| Quote-Driven | Uses the quotes received during the RFQ process to construct a dynamic benchmark. | Reflects the actual market conditions at the time of the trade; captures information revealed during the RFQ. | Can be skewed by strategic quoting behavior; requires a sufficient number of quotes to be reliable. |

## Mitigating Information Leakage

Information leakage is a significant risk in the RFQ process, particularly for large trades in illiquid assets. When an initiator sends out an RFQ to multiple dealers, they are revealing their trading intention to the market. This information can be used by the dealers to their advantage, either by pre-hedging their positions or by widening their quotes. A key part of any TCA strategy for illiquid RFQs is to implement measures to mitigate this risk.

There are several strategies that can be employed to reduce information leakage:

- **Selective RFQ** ▴ Instead of sending an RFQ to a large number of dealers, a more selective approach can be taken. This involves identifying a small group of dealers who are known to be reliable market makers in the asset being traded and who have a good track record of providing competitive quotes.

- **Staggered RFQ** ▴ Another approach is to stagger the RFQ process. This involves sending out the RFQ to a small number of dealers initially, and then expanding the group if the initial quotes are not competitive. This can help to reduce the amount of information that is leaked to the market at any one time.

- **Anonymous RFQ** ▴ Some trading platforms offer anonymous RFQ functionality, which allows the initiator to send out an RFQ without revealing their identity. This can be an effective way to reduce information leakage, as it makes it more difficult for dealers to identify the initiator and to use that information to their advantage.

## What Is the Trade-Off between Competition and Information Leakage?

There is an inherent trade-off between maximizing competition and minimizing information leakage. Sending an RFQ to a larger number of dealers will increase competition and potentially lead to a better price. However, it will also increase the risk of information leakage. The optimal strategy will depend on the specific circumstances of the trade.

For a large, sensitive trade in an illiquid asset, it may be preferable to sacrifice some competition in order to minimize the risk of information leakage. For a smaller, less sensitive trade, a wider RFQ may be more appropriate.

## Execution

The execution of a robust [transaction cost](https://prime.greeks.live/area/transaction-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) analysis framework for illiquid RFQs is a multi-faceted process that requires a combination of [quantitative modeling](https://prime.greeks.live/area/quantitative-modeling/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), technological infrastructure, and disciplined operational procedures. It is about building a system that can capture the nuances of illiquid markets and provide actionable insights to traders and portfolio managers. This system must be able to move beyond simple, static benchmarks and embrace a more dynamic and context-aware approach to measuring execution quality.

The foundation of this system is data. High-quality data is the lifeblood of any effective [TCA framework](https://prime.greeks.live/area/tca-framework/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This includes not only the traditional trade data (price, volume, time) but also a rich set of pre-trade and post-trade data.

Pre-trade data includes the quotes received during the RFQ process, the characteristics of the asset being traded, and the prevailing market conditions. Post-trade data includes information about the settlement of the trade, the performance of the asset after the trade, and any other relevant market color.

> A successful execution framework for illiquid TCA is one that transforms raw data into a clear, coherent narrative of execution quality.

This narrative is not just for a post-mortem analysis of past trades. It is a real-time feedback loop that can be used to improve future trading decisions. A trader who has access to a rich set of TCA data is better equipped to negotiate with dealers, to identify the best sources of liquidity, and to manage the risks of trading in illiquid markets.

## The Operational Playbook

Implementing a sophisticated TCA framework for illiquid RFQs requires a disciplined and systematic approach. The following operational playbook outlines the key steps involved in this process:

- **Data Collection and Warehousing** ▴ The first step is to establish a robust data collection and warehousing infrastructure. This involves capturing all relevant data points, from the initial RFQ to the final settlement of the trade. The data should be stored in a structured and easily accessible format, allowing for efficient analysis.

- **Benchmark Selection and Calibration** ▴ The next step is to select and calibrate the appropriate benchmarks for each trade. This will involve a combination of the alternative benchmarking frameworks discussed in the previous section. The selection of the benchmark should be documented and justified for each trade.

- **TCA Calculation and Reporting** ▴ Once the benchmarks have been selected, the TCA can be calculated. This will involve comparing the executed price to the benchmark and calculating a range of metrics, such as the implementation shortfall, the price impact, and the opportunity cost. The results of the TCA should be presented in a clear and concise report, with visualizations and narrative explanations to provide context.

- **Performance Attribution and Feedback** ▴ The final step is to use the results of the TCA to attribute performance and to provide feedback to the trading desk. This will involve identifying the key drivers of execution quality, such as the choice of dealer, the timing of the trade, and the trading strategy employed. This feedback can then be used to refine the trading process and to improve future performance.

## Quantitative Modeling and Data Analysis

Quantitative modeling plays a critical role in a sophisticated TCA framework for illiquid RFQs. It is used to build the regression-based benchmarks, to estimate the price impact of trades, and to identify patterns in trading data that can be used to improve execution quality. One of the key challenges in quantitative modeling for illiquid assets is the scarcity of data. This requires the use of specialized statistical techniques that are designed to work with small and noisy datasets.

The following table provides an example of a regression-based benchmark for a corporate bond. The model predicts the spread of the bond over a benchmark government bond based on a set of credit and liquidity factors.

### Regression-Based Benchmark for a Corporate Bond

| Variable | Coefficient | Standard Error | P-value |
| --- | --- | --- | --- |
| Intercept | 0.50 | 0.10 | |
| Credit Rating (AAA=1, AA=2, etc.) | 0.25 | 0.05 | |
| Time to Maturity (years) | 0.05 | 0.01 | |
| Issue Size ($ billions) | -0.10 | 0.02 | |
| Bid-Ask Spread (basis points) | 0.80 | 0.15 | |

The model shows that the bond’s spread is positively related to its credit rating and time to maturity, and negatively related to its issue size. The [bid-ask spread](https://prime.greeks.live/area/bid-ask-spread/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is also a significant predictor of the bond’s spread, highlighting the importance of liquidity in pricing. This model can be used to generate a benchmark spread for any bond with a given set of characteristics. The executed spread can then be compared to this benchmark to assess the quality of the execution.

## How Can We Validate the Accuracy of These Quantitative Models?

The validation of [quantitative models](https://prime.greeks.live/area/quantitative-models/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a critical step in the execution of a TCA framework. This involves testing the model’s performance on a hold-out sample of data that was not used to build the model. The model’s predictions can be compared to the actual traded prices in the hold-out sample to assess its accuracy. It is also important to regularly review and recalibrate the model to ensure that it remains relevant as market conditions change.

## Predictive Scenario Analysis

To illustrate the application of this advanced TCA framework, consider the case of a portfolio manager at a large asset management firm who needs to sell a $50 million block of a 10-year, single-A rated corporate bond. The bond is relatively illiquid, with an average daily trading volume of less than $5 million. The firm’s TCA system, which has been built according to the principles outlined above, swings into action.

The first step is to generate a pre-trade analysis report. The system’s regression-based model predicts a benchmark spread of 125 [basis points](https://prime.greeks.live/area/basis-points/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) over the 10-year Treasury bond. The system also pulls in data on recent trades in similar bonds, which suggests a trading range of 120 to 130 basis points. The trader, armed with this information, decides to send out a selective RFQ to five dealers who are known to be active in this particular bond.

The quotes come back as follows:

- **Dealer A** ▴ 128 bps

- **Dealer B** ▴ 126 bps

- **Dealer C** ▴ 132 bps

- **Dealer D** ▴ 127 bps

- **Dealer E** ▴ 125 bps

The trader executes the trade with Dealer E at 125 basis points. A traditional TCA system, using the midpoint of the best bid and offer from a vendor feed (which was 124 bps), would have shown a cost of 1 basis point. The advanced TCA system, however, provides a much richer analysis. The system calculates a quote-driven benchmark of 127.6 basis points (the simple average of the five quotes).

Against this benchmark, the execution at 125 basis points represents a savings of 2.6 basis points, or $13,000 on the $50 million trade. The system also flags that Dealer E has consistently provided the tightest quotes for this type of bond over the past six months, providing valuable feedback for future dealer selection.

## System Integration and Technological Architecture

The technological architecture of a sophisticated TCA system for illiquid RFQs must be designed to handle the unique challenges of these markets. This includes the ability to ingest and process a wide variety of data types, to run complex quantitative models in near real-time, and to provide intuitive and actionable reports to traders and portfolio managers. The system should be integrated with the firm’s Order Management System (OMS) and Execution Management System (EMS), allowing for a seamless flow of data and a closed-loop feedback process.

The system should also be designed with flexibility and scalability in mind. The world of illiquid markets is constantly evolving, and the TCA system must be able to adapt to new asset classes, new trading protocols, and new sources of data. This requires a modular architecture that allows for new components to be added or existing components to be updated without disrupting the entire system. A cloud-based architecture can provide the flexibility and scalability needed to meet these challenges.

## Reflection

The transition from a simplistic midpoint benchmark to a sophisticated, multi-faceted TCA framework is a significant undertaking. It requires a commitment of resources, a willingness to challenge long-held assumptions, and a culture of continuous improvement. The rewards, however, are substantial.

A firm that can accurately measure and manage its transaction costs in illiquid markets has a significant competitive advantage. It can provide better execution for its clients, reduce its own trading costs, and make more informed investment decisions.

## What Does Your Current TCA Framework Reveal about Your Trading Process?

Take a moment to consider your own firm’s approach to TCA for illiquid RFQs. Are you still relying on a simple midpoint benchmark? Or have you begun to explore more sophisticated alternatives? What does your current framework tell you about your trading process?

Does it provide you with the insights you need to improve your performance? Or does it simply check a box for compliance purposes? The answers to these questions will reveal much about your firm’s commitment to achieving a true execution edge.

It is a function of several variables, including the size of the trade, the complexity of the instrument, and the reputation of the counterparties. A large trade in a complex, opaque instrument from a well-informed hedge fund will be treated with far more caution by market makers than a small trade in a more standardized instrument from a less sophisticated client. A robust TCA system must be able to account for these factors. A simple midpoint benchmark is a blunt instrument, incapable of capturing the nuances of these information-rich interactions."

Sending an RFQ to a larger number of dealers will increase competition and potentially lead to a better price. However, it will also increase the risk of information leakage. The optimal strategy will depend on the specific circumstances of the trade. For a large, sensitive trade in an illiquid asset, it may be preferable to sacrifice some competition in order to minimize the risk of information leakage. For a smaller, less sensitive trade, a wider RFQ may be more appropriate."

This involves testing the model's performance on a hold-out sample of data that was not used to build the model. The model's predictions can be compared to the actual traded prices in the hold-out sample to assess its accuracy. It is also important to regularly review and recalibrate the model to ensure that it remains relevant as market conditions change."

                "text": "Take a moment to consider your own firm's approach to TCA for illiquid RFQs. Are you still relying on a simple midpoint benchmark? Or have you begun to explore more sophisticated alternatives? What does your current framework tell you about your trading process? Does it provide you with the insights you need to improve your performance? Or does it simply check a box for compliance purposes? The answers to these questions will reveal much about your firm's commitment to achieving a true execution edge."
