## Concept

The scenario presented ▴ a security with a solitary [market maker](https://prime.greeks.live/question/how-does-market-fragmentation-directly-influence-a-market-makers-quoting-strategy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ▴ moves the conversation about [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) from a comparative exercise to a procedural one. In a liquid market, the obligation is often satisfied by surveying multiple, competing quotes and selecting the optimal one based on a range of factors. When only one source of liquidity exists, the entire analytical framework must be re-calibrated. The challenge becomes one of demonstrating diligence and establishing a record of fair dealing in a market structure that offers no external benchmarks for comparison.

The focus shifts from price discovery across multiple venues to [price verification](https://prime.greeks.live/area/price-verification/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) against a set of internally consistent and externally validatable metrics. It is a fundamental test of a firm’s internal controls and its commitment to a fiduciary standard, demanding a systematic approach to justify every execution.

At its heart, the regulatory mandate for best execution persists, regardless of market structure. Authorities like the [Financial Industry Regulatory Authority](https://prime.greeks.live/question/what-regulatory-frameworks-govern-the-use-of-opaque-models-in-the-financial-industry/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (FINRA) in the U.S. and the European Securities and Markets Authority (ESMA) require firms to use “reasonable diligence” to ascertain that the price is as favorable as possible under prevailing conditions. In a single-market-maker environment, “reasonable diligence” cannot be proven through a simple comparison of contemporaneous quotes.

Instead, it must be constructed from a mosaic of data points that, when viewed together, form a coherent and defensible argument for the fairness of the execution. This involves a deep analysis of the security’s characteristics, the market maker’s pricing methodology, and the broader market context at the time of the trade.

> The core obligation shifts from a selection among competing options to a rigorous validation of a single available price.

This validation process is an architectural challenge. It requires building a system that captures, analyzes, and archives a wide range of pre-trade, at-trade, and post-trade data. The system must be capable of demonstrating that the firm did not simply accept the market maker’s price passively but actively engaged in a process to ensure it was fair and reasonable. This process becomes the evidence.

It is the firm’s primary defense against any subsequent inquiry into its execution quality. The absence of competitive quotes elevates the importance of every other piece of information, turning the firm’s internal documentation and analytical procedures into the primary evidence of compliance. The firm must, in effect, create its own benchmark where the public market provides none.

## Strategy

In a market defined by a single liquidity provider, a firm’s strategy for demonstrating best execution must be deliberate, documented, and robust. It is a pivot from a reactive, quote-driven process to a proactive, evidence-gathering one. The objective is to construct a defensible narrative for each trade, supported by a comprehensive framework of analysis and documentation. This framework serves as a proxy for the competitive tension that is absent from the market itself.

It is built on two primary pillars ▴ a rigorous [pre-trade analysis protocol](https://prime.greeks.live/question/how-does-pre-trade-analysis-differ-from-post-trade-analysis-in-practice/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and a systematic [post-trade review](https://prime.greeks.live/area/post-trade-review/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) process. The combination of these pillars provides the necessary structure to validate execution quality in the absence of direct, contemporaneous price competition.

## Pre-Trade Diligence and Price Justification

The pre-trade phase is the most critical for establishing a defensible position. Before an order is placed, the firm must build a case for the fairness of the anticipated [execution price](https://prime.greeks.live/question/how-can-institutions-differentiate-between-price-reversion-and-trading-along-a-genuine-price-trend/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This involves moving beyond the price itself and analyzing the factors that contribute to it.

A key strategic element is the formalization of a “[Fair Price Framework](https://prime.greeks.live/area/fair-price-framework/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite),” a documented methodology for evaluating the price offered by the sole market maker. This framework should be consistently applied and regularly reviewed for its effectiveness.

Elements of a robust Fair [Price Framework](https://prime.greeks.live/question/how-can-a-transaction-cost-analysis-framework-differentiate-between-price-impact-and-adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) include:

- 
**Analysis of Related Securities** ▴ The framework should mandate the analysis of prices and volatility in correlated assets. For a specific corporate bond, this might involve looking at the issuer’s other outstanding debt, credit default swaps (CDS) on the issuer, or even the performance of its equity. The goal is to establish a “zone of reasonableness” for the price, based on the behavior of related instruments in more liquid markets.

- 
**Use of Third-Party Pricing Services** ▴ Where available, data from independent pricing services should be incorporated. While these services may not provide executable quotes, they offer an objective, [third-party valuation](https://prime.greeks.live/question/how-do-internal-models-differ-from-third-party-quotes-in-derivatives-valuation/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that can be used as a benchmark. Discrepancies between the market maker’s price and the third-party valuation must be investigated and documented.

- 
**Internal Valuation Models** ▴ For certain types of securities, particularly complex derivatives or structured products, the firm should maintain its own internal valuation models. These models, based on standard industry practices and subject to independent validation, can generate a theoretical fair value for the security. The model’s inputs and the resulting valuation provide a powerful data point for the [pre-trade analysis](https://prime.greeks.live/area/pre-trade-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

> A structured pre-trade analysis protocol is the foundation for demonstrating that a firm is not a passive price-taker but an active fiduciary.

## Documenting the Factors Considered

A critical component of the strategy is the creation of a standardized pre-trade documentation package for each order. This package should be an auditable record of the firm’s diligence. It serves as concrete evidence that a thoughtful, systematic process was followed. The table below outlines a potential structure for such a documentation package, ensuring all relevant factors are considered and recorded.

### Table 1 ▴ Pre-Trade Execution Factors Checklist

| Factor Category | Specific Consideration | Data Source / Methodology | Analyst Notes & Justification |
| --- | --- | --- | --- |
| Price | Comparison to recent trades in the same security. | Internal Trade History; TRACE (if applicable). | Last trade was 3 days ago at 98.50. Current quote is 98.60, consistent with market drift. |
| Costs | Analysis of explicit commissions or spread. | Direct communication with market maker; historical cost analysis. | Spread is consistent with past trades of similar size and complexity. |
| Speed | Not applicable as a comparative metric, but timing of execution relative to market events is key. | Market news feeds; internal assessment of urgency. | Execution timed to avoid known market-moving data releases. |
| Likelihood of Execution | Confirmation of market maker’s capacity and willingness to trade the required size. | Direct communication (RFQ). | Market maker confirmed capacity for the full order size. |
| Size and Nature | Assessment of the order’s size relative to typical volume. | Historical trade data. | Order represents a significant portion of average weekly volume, justifying direct negotiation. |
| Other Considerations | Valuation from third-party pricing service. | Bloomberg Valuation (BVAL), Refinitiv. | BVAL price is 98.55. Market maker quote of 98.60 is within an acceptable tolerance band. |

## Post-Trade Review and Continuous Improvement

The strategy does not end with the execution of the trade. A robust post-trade review process is essential for demonstrating ongoing diligence and for refining the firm’s execution strategy over time. This process should be systematic and conducted on a regular basis, at least quarterly, as part of a “regular and rigorous” review cycle. The goal is to analyze execution quality historically, identify any patterns of concern, and demonstrate that the firm is actively monitoring the performance of the sole market maker.

Key components of the post-trade review include:

- 
**Periodic Price Benchmarking** ▴ The firm should conduct retrospective analyses of the prices it received. This can involve comparing the execution prices against the third-party valuation data for the trade date, or against the performance of correlated securities over a subsequent period. The analysis seeks to answer the question ▴ “In hindsight, was the price we received fair?”

- 
**Analysis of Market Maker Performance** ▴ The review should assess the market maker on factors beyond price. This includes the quality of settlement, the speed of response to inquiries, and the consistency of pricing. Any issues should be documented and, if necessary, raised with the market maker.

- 
**Policy and Framework Review** ▴ The post-trade review is an opportunity to assess the effectiveness of the firm’s own [Fair Price](https://prime.greeks.live/area/fair-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Framework. The firm should ask whether its pre-trade analysis is capturing the right information and whether its valuation models are performing as expected. The policy should be a living document, updated in response to these findings.

This continuous loop of pre-trade analysis, execution, and post-trade review creates a powerful evidentiary record. It demonstrates that the firm understands its obligations and has implemented a comprehensive strategy to meet them, even in the most challenging of market structures. It transforms the problem from one of market limitation to one of procedural strength.

## Execution

The execution phase in a single-market-maker scenario is the operational manifestation of the firm’s strategy. It is where the abstract principles of diligence and fairness are translated into a concrete, auditable workflow. This workflow must be meticulously designed and flawlessly executed to produce the evidence required to demonstrate best execution.

The focus is on creating a repeatable, systematic process that leaves no room for ambiguity and generates a comprehensive audit trail for every transaction. This process can be broken down into a series of distinct operational sub-chapters, from the initial order handling to the final archival of trade data.

## The Operational Playbook for Single-Provider Execution

A firm must implement a detailed [operational playbook](https://prime.greeks.live/guide/the-institutional-playbook-for-rfq-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that guides traders and compliance staff through the entire lifecycle of an order in a single-provider security. This playbook is a procedural document that ensures consistency and completeness in the firm’s execution practices. It is the firm’s internal law for handling these specific types of trades.

- 
**Order Inception and Initial Triage** ▴ Upon receipt of a client order, the first step is to identify the security as one with a [single market maker](https://prime.greeks.live/area/single-market-maker/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This classification should trigger the specific handling procedures outlined in the playbook. The order details, including size, side (buy/sell), and any client-specific instructions, are formally logged in the [Order Management System](https://prime.greeks.live/area/order-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (OMS).

- 
**Activation of Pre-Trade Analysis Protocol** ▴ The trader initiates the pre-trade analysis as mandated by the Fair Price Framework. This is a non-negotiable step. The trader systematically gathers the required data points, including recent trade history, third-party valuations, and analysis of correlated securities. All findings are logged in a dedicated pre-trade checklist associated with the order in the OMS.

- 
**Formal Request for Quote (RFQ)** ▴ The trader issues a formal RFQ to the sole market maker. The communication should be conducted over a recorded channel, such as a recorded phone line or a secure electronic messaging platform. The RFQ should clearly state the security and the desired size of the transaction.

- 
**Quote Evaluation and Justification** ▴ Upon receiving the quote, the trader evaluates it against the pre-trade analysis. If the quote is within the pre-determined tolerance band of the benchmark data, the trader can proceed. If it falls outside, the playbook must require the trader to challenge the quote.
This challenge, and the market maker’s response, must be documented. The trader must record a formal justification for accepting the final price, referencing the pre-trade analysis.

- 
**Execution and Confirmation** ▴ The trade is executed, and the details are immediately recorded. The execution time, price, and size are captured to the millisecond. A formal confirmation is sent to the client, which should also include a statement that the trade was executed in accordance with the firm’s best execution policy.

- 
**Post-Trade Data Assembly and Archiving** ▴ All documents related to the trade are assembled into a single electronic folder. This includes the pre-trade checklist, records of communication with the market maker, the final price justification, and the trade confirmation. This “deal file” is the primary evidence of the firm’s diligence and must be securely archived and easily retrievable for compliance reviews.

## Quantitative Modeling and Data Analysis

Quantitative analysis is the backbone of a defensible best execution process in this context. It provides the objective data needed to support the qualitative judgments made by the trader. The firm must maintain a systematic approach to data collection and analysis, applying quantitative techniques to both pre-trade and post-trade evaluations.

The following table illustrates the type of data that should be captured and analyzed as part of the post-trade “regular and rigorous” review process. This analysis helps to identify trends and provides a quantitative basis for evaluating the market maker’s performance over time.

> Systematic data analysis transforms the subjective challenge of fairness into an objective, evidence-based conclusion.

### Table 2 ▴ Quarterly Post-Trade Transaction Cost Analysis (TCA) for a Single-Maker Security

| Trade Date | Execution Price | Third-Party Valuation (End of Day) | Price Slippage (bps) | Correlated Asset Index (Daily Change %) | Notes |
| --- | --- | --- | --- | --- | --- |
| 2025-07-15 | 99.25 | 99.20 | +5.0 | +0.10% | Execution price slightly above valuation, consistent with positive market tone. |
| 2025-08-02 | 98.50 | 98.60 | -10.0 | -0.25% | Favorable execution relative to valuation on a negative market day. |
| 2025-08-21 | 98.75 | 98.70 | +5.0 | +0.05% | Within normal tolerance. |
| 2025-09-10 | 97.80 | 97.80 | 0.0 | -0.15% | Execution price matched valuation exactly. |

In this analysis, “Price Slippage” is calculated as ▴ ((Execution Price / Third-Party Valuation) – 1) 10,000. A positive value indicates the execution price was higher than the valuation, which is unfavorable for a purchase. The analysis aims to show that, on average, the firm is achieving prices that are fair relative to an objective benchmark, even if individual trades show minor deviations.

## System Integration and Technological Architecture

The operational playbook and quantitative analysis must be supported by a robust technological architecture. Manual, paper-based processes are prone to error and are insufficient for creating the kind of high-integrity audit trail required. The firm’s technology stack must be configured to support and enforce the best execution workflow.

- 
**Order Management System (OMS)** ▴ The OMS is the central hub of the process. It must be configured with a specific workflow for single-provider securities. This includes mandatory fields for the pre-trade checklist, a mechanism to link communications records to the order, and automated alerts for any deviation from the playbook.

- 
**Data Integration** ▴ The OMS should have real-time data feeds from third-party pricing services and market data providers. This allows the trader to access the necessary benchmark data directly within their workflow, rather than having to consult separate systems. This integration reduces the risk of error and ensures consistency.

- 
**Communications Archiving** ▴ The firm must have a system for recording and archiving all communications related to a trade. This includes recorded phone lines for voice trading and an archiving solution for electronic messages (e.g. Bloomberg mail, chat). These records must be time-stamped and easily searchable by trade ID.

- 
**Compliance and Surveillance Systems** ▴ The firm’s compliance systems should be configured to automatically flag all trades in single-provider securities for review. These systems can also be used to run the periodic quantitative analyses, generating reports for the Best Execution Committee or equivalent governing body. This automated surveillance provides an independent check on the execution process and demonstrates a commitment to oversight.

Ultimately, the execution of this strategy is about building a fortress of evidence. Each component ▴ the playbook, the quantitative analysis, and the technology ▴ is a stone in the wall. Together, they create a structure that is capable of withstanding the most intense regulatory scrutiny, proving that even in the absence of competition, the firm upheld its fiduciary duty to its clients.

## A System of Procedural Integrity

The challenge of a single-market-maker security forces a firm to look inward. It compels a transition from relying on the market for justification to building justification from within. The frameworks and protocols discussed are components of a larger system ▴ a system of procedural integrity.

This internal architecture is a direct reflection of the firm’s operational philosophy and its commitment to its clients. The absence of external competition does not create a regulatory vacuum; it creates a demand for a more robust internal structure.

Consider the operational playbook not as a set of rules to be followed, but as the source code for the firm’s fiduciary duty. How is this code maintained, reviewed, and improved? Is it a static document, or a dynamic system that learns from every trade and every post-trade review?

The strength of this system is the ultimate measure of the firm’s ability to deliver and demonstrate best execution. It is the definitive answer to the question of how a firm acts in its clients’ best interests when no one else is quoting a price.
