## Concept

A firm’s [best execution policy](https://prime.greeks.live/area/best-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) represents the operational nervous system for its trading function. For liquid, exchange-traded instruments, this system is calibrated to a world of transparent prices and centralized liquidity. Introducing illiquid or over-the-counter (OTC) instruments forces a fundamental re-architecture of this system.

The challenge is one of translation; applying a framework built for certainty to an environment defined by its absence. The core objective of the policy ceases to be about finding the “best” price on a screen and transforms into a documented process of diligence to construct a “fair” price in the absence of one.

The very nature of these instruments ▴ bespoke, infrequently traded, and subject to bilateral negotiation ▴ means that the concept of a single, verifiable best price is a fiction. Consequently, the policy must pivot from a simple price-and-time hierarchy to a multi-factor model where qualitative judgments are as critical as quantitative inputs. It becomes a governance document, a framework for decision-making under uncertainty, and a defensive record of reasonable diligence. The policy’s primary function is to provide a systematic, repeatable, and justifiable methodology for navigating markets where the key [execution factors](https://prime.greeks.live/area/execution-factors/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ▴ price, cost, speed, likelihood of execution, and settlement finality ▴ are in constant tension.

> A robust policy for illiquid assets codifies the firm’s judgment in navigating opaque markets, transforming subjective decisions into a structured, defensible process.

## Defining the Scope of Illiquidity

An effective policy begins with a precise, internally consistent definition of what constitutes an “illiquid” or “OTC” instrument for the purposes of execution. This definition is not static; it is a dynamic classification based on a range of quantitative and qualitative factors. A security’s classification dictates the entire execution protocol that follows. The policy must establish clear thresholds and criteria for this classification process.

Factors to consider for this classification include:

- **Average Daily Volume (ADV)** ▴ Establishing internal thresholds below which a security is automatically subjected to enhanced execution protocols.

- **Bid-Ask Spread** ▴ Defining what constitutes a wide spread relative to the instrument’s asset class, signaling potential illiquidity and higher transaction costs.

- **Market Depth** ▴ Assessing the volume available at or near the inside quote, with shallow depth indicating that even moderately sized orders could have a significant [market impact](https://prime.greeks.live/area/market-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

- **Quotation Availability** ▴ The number of market makers or dealers providing consistent, actionable quotes for an instrument is a direct measure of its liquidity and the competitiveness of its market structure.

By codifying these definitions, the firm creates a clear trigger mechanism. When an order for an instrument meeting these criteria is generated, it is automatically routed into the specialized workflow designed for [illiquid assets](https://prime.greeks.live/area/illiquid-assets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), ensuring that the appropriate level of diligence and documentation is applied from the outset.

## The Shift from Price Taker to Price Maker

In liquid markets, a firm is largely a price taker, interacting with an established market price. For [illiquid instruments](https://prime.greeks.live/area/illiquid-instruments/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), the firm and its counterparty are effectively price makers, constructing a price through negotiation and analysis. The best [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) must formally acknowledge this shift. It needs to detail the procedures for this price discovery process, ensuring it is fair, systematic, and serves the client’s best interest.

This involves a structured approach to gathering market intelligence. The policy should mandate the collection of data points that serve as proxies for a fair market value. These can include recent trade prices in the same or similar instruments, indicative quotes from multiple dealers, and valuations derived from internal models. The policy provides the blueprint for how this information is sourced, evaluated, and used to justify the final [execution price](https://prime.greeks.live/area/execution-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), creating an auditable trail that substantiates the fairness of the negotiated outcome.

## Strategy

The strategic core of a [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) policy for illiquid instruments is the formalization of a multi-dimensional approach to [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The strategy moves beyond the singular pursuit of the best possible price to encompass a broader set of objectives tailored to the unique risks of OTC markets. This requires building a robust governance structure, defining a clear hierarchy of execution factors, and selecting appropriate execution methodologies that align with the specific characteristics of the asset and the trade.

This strategic framework serves as the bridge between the conceptual understanding of the challenge and the operational execution of the solution. It is where the firm codifies its risk appetite, its standards of diligence, and its commitment to client outcomes in markets defined by opacity and fragmentation. A successful strategy ensures that every trading decision is made within a consistent, defensible, and well-understood framework.

## Constructing a Governance and Oversight Framework

A specific governance structure is paramount. The policy must establish a Best Execution Committee or a similar oversight body with a clear mandate. This committee’s responsibilities should be explicitly defined and include:

- **Policy Review** ▴ At least annually, the committee must review and update the policy to reflect changes in market structure, regulation, and available execution technologies.

- **Venue Analysis** ▴ The committee is responsible for the ongoing review and approval of execution venues and counterparties. This involves assessing counterparty credit risk, settlement efficiency, and the quality of their [price discovery](https://prime.greeks.live/area/price-discovery/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) processes.

- **Exception Review** ▴ Any trades that deviate from the established policy must be reviewed by the committee to determine if the deviation was justified and in the client’s best interest.

- **Performance Monitoring** ▴ The committee oversees the [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) function, reviewing reports to identify trends, assess the effectiveness of execution strategies, and ensure continuous improvement.

## What Are the Critical Execution Factors for OTC Instruments?

For illiquid instruments, the relative importance of the standard execution factors shifts dramatically. The policy must provide a clear, yet flexible, framework for prioritizing these factors based on the specific context of each order. While price is always a consideration, it is often subordinated to other, more critical factors.

The strategic framework must guide traders in weighing these competing priorities:

- **Certainty of Execution and Settlement** ▴ In highly illiquid markets, the ability to complete the trade at all can be the single most important factor. The risk of failed settlement or a counterparty backing away from a quote is substantial. Therefore, the creditworthiness and reliability of the counterparty often take precedence over a marginally better price.

- **Minimizing [Information Leakage](https://prime.greeks.live/question/how-can-a-leakage-model-differentiate-between-market-impact-and-systemic-information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ Large orders in illiquid instruments are highly susceptible to market impact. A poorly managed execution process can alert other market participants, leading to adverse price movements before the full order can be completed. The policy must prioritize execution methods, like [Request for Quote](https://prime.greeks.live/area/request-for-quote/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (RFQ) to a limited set of trusted counterparties, that protect the confidentiality of the order.

- **Total Cost of the Transaction** ▴ This extends beyond the explicit price to include implicit costs like market impact and opportunity cost. The policy should mandate a total [cost analysis](https://prime.greeks.live/area/cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) framework that captures these hidden expenses, providing a more holistic view of execution quality.

- **Fairness of Price** ▴ Given the absence of a consistent market price, the objective becomes ensuring a “fair” price. The policy must define the process for establishing fairness, such as benchmarking against internal valuation models or obtaining multiple indicative quotes.

> For illiquid assets, the strategy is not about finding the perfect price, but about perfecting the process used to arrive at a fair one.

Its central crystalline core represents high-fidelity execution and atomic settlement](https://options.greeks.live/wp-content/uploads/2025/07/institutional-digital-asset-derivatives-rfq-execution-engine-microstructure.jpg)

## Selecting the Appropriate Execution Methodology

The policy must outline the approved execution methodologies and the conditions under which each should be used. The choice of method is a strategic decision designed to align with the prioritized execution factors for a given trade. The firm must document its rationale for selecting a particular channel.

### Table 1 ▴ Comparison of Execution Methodologies for Illiquid Instruments

| Methodology | Primary Strengths | Primary Weaknesses | Best Suited For |
| --- | --- | --- | --- |
| Request for Quote (RFQ) | Controlled information leakage; competitive pricing from a select group of dealers. | Risk of collusion among dealers; price may not reflect the broader market. | Standardized OTC derivatives, municipal bonds, and corporate bonds where a competitive dealer network exists. |
| Voice Brokerage | Access to deep pools of liquidity; high-touch handling for complex or very large orders. | High potential for information leakage; higher explicit costs; difficult to systematize for TCA. | Highly structured or bespoke products; very large block trades in illiquid securities. |
| Direct Counterparty Negotiation | Maximum privacy; ability to execute very large size with a single trusted counterparty. | Complete lack of price competition; heavy reliance on post-trade analysis to ensure fairness. | Unique, non-standardized OTC derivatives; situations requiring absolute discretion. |
| Organised Trading Facility (OTF) | Increased transparency over pure OTC; formalizes discretionary trading within a regulated framework. | Liquidity can still be fragmented; may not exist for the most esoteric instruments. | Less liquid bonds and standardized derivatives that fall under regulatory mandates like MiFID II. |

## Execution

The execution phase of the policy translates the firm’s strategic objectives into a concrete, auditable series of actions. This is the operational playbook that guides traders and compliance officers through the lifecycle of an illiquid trade. It requires a granular definition of procedures for pre-trade analysis, at-trade documentation, and post-trade review. The goal is to create a system where the diligence applied to each trade is demonstrable and consistent.

Effective execution in this context is defined by process. It relies on the systematic collection of data, the rigorous application of analytical tools, and the disciplined documentation of every decision. This operational rigor is the firm’s primary defense against regulatory scrutiny and the most reliable path to achieving fair outcomes for clients in challenging market conditions.

## Pre-Trade Diligence and Price Discovery

Before an order is placed, the policy must mandate a formal pre-trade analysis. The objective is to establish a justifiable benchmark against which the eventual execution can be judged. This process must be documented and archived for every illiquid trade.

- **Instrument Classification** ▴ The first step is to formally classify the instrument using the firm’s predefined criteria for illiquidity. This action triggers the enhanced execution protocol.

- **Benchmark Selection** ▴ A [pre-trade benchmark price](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) must be established. Depending on the instrument, this could be:

<li>The last traded price, adjusted for market movements since the trade occurred.

- A valuation from a third-party pricing service or an internal model.

- The average of indicative quotes solicited from multiple dealers.

</li>
- **Counterparty Selection** ▴ The trader must document the rationale for selecting the counterparties from whom quotes will be requested or with whom negotiations will be conducted. This selection should be based on the approved counterparty list and factors like creditworthiness and historical execution quality.

- **Execution Strategy Documentation** ▴ The trader must record the chosen execution methodology (e.g. RFQ to three dealers) and the rationale for this choice, linking it back to the prioritized execution factors (e.g. minimizing information leakage for a large order).

## How Does a Firm Document Reasonable Diligence at the Point of Trade?

At the point of execution, the focus shifts to creating a contemporaneous record of the actions taken to achieve a fair outcome. This documentation is critical, as it provides the primary evidence of the firm’s adherence to its best execution obligations.

The policy should require the capture of the following information at the time of the trade:

- **All [Quotes Received](https://prime.greeks.live/question/in-an-illiquid-market-how-can-best-execution-be-demonstrated-when-very-few-rfq-responses-are-received/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ For RFQs, all solicited quotes ▴ both winning and losing ▴ must be recorded with timestamps.

- **Negotiation Records** ▴ For voice-brokered or directly negotiated trades, detailed notes of the negotiation, including key terms discussed and prices offered, must be maintained.

- **Justification for Execution** ▴ The trader must provide a concise justification for why the final executed price is considered fair and in the best interest of the client, referencing the [pre-trade benchmark](https://prime.greeks.live/area/pre-trade-benchmark/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and the quotes received. For example ▴ “Executed at 99.50 with Counterparty B. This was the best of three quotes received and was 0.25 points inside our pre-trade valuation model’s [fair value](https://prime.greeks.live/area/fair-value/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) estimate of 99.25.”

- **Market Conditions** ▴ A brief note on the prevailing market conditions (e.g. “high volatility,” “thin liquidity”) should be included to provide context for the execution outcome.

## Post-Trade Review and Transaction Cost Analysis (TCA)

The post-trade review process is where the firm validates the effectiveness of its policy and execution strategies. It is a continuous feedback loop designed to improve future performance. A specialized TCA framework is required for illiquid instruments, focusing on metrics that capture the unique challenges of these markets.

> In illiquid markets, transaction cost analysis is less about measuring against an ideal price and more about evaluating the quality of the decision-making process.

The Best Execution Committee should review TCA reports on at least a quarterly basis. The reports must be designed to answer key questions ▴ Are our chosen counterparties providing competitive pricing? Are our execution strategies effectively minimizing market impact? Are there patterns in our trading that suggest a need to update our policy?

### Table 2 ▴ Transaction Cost Analysis Framework for Illiquid OTC Instruments

| Metric | Definition | Purpose | Data Requirements |
| --- | --- | --- | --- |
| Benchmark Slippage | Difference between the execution price and the pre-trade benchmark price. | Measures the effectiveness of the price discovery and negotiation process. | Pre-trade benchmark price; final execution price. |
| Quote Spread Analysis | The difference between the best quote received and the average of all quotes received. | Assesses the competitiveness of the dealer network for a given instrument. | All quotes received for a specific RFQ. |
| Price Reversion | Measures price movement in the period immediately following the execution. Significant reversion may indicate market impact. | Identifies trades that may have caused undue market impact, suggesting a need for a more passive execution strategy. | Execution price; post-trade market prices (T+5min, T+30min). |
| Counterparty Performance Scorecard | A composite score for each counterparty based on quote competitiveness, response rate, and settlement efficiency. | Provides a quantitative basis for managing the approved counterparty list. | Historical quote data; settlement records; qualitative feedback from traders. |

## From Static Policy to Dynamic System

The document outlining a firm’s best execution policy for illiquid assets is a static artifact. The market it governs is a dynamic, adaptive system. The ultimate challenge, therefore, is to ensure the policy functions as a learning mechanism, not just a rulebook. How does the accumulated data from your execution process ▴ the TCA reports, the counterparty scorecards, the documented exceptions ▴ feed back into the evolution of your strategic framework?

An execution policy is a snapshot of the firm’s best thinking at a point in time. A true execution system is one that continually refines that thinking in response to new information, ensuring that the firm’s operational architecture adapts as quickly as the markets themselves.
