## Concept

The question of achieving [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) on an illiquid trade with a [single counterparty](https://prime.greeks.live/area/single-counterparty/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) presents a fundamental tension within market structure. Your experience correctly identifies the core of the challenge. An asset is defined as illiquid precisely because of a shallow pool of available buyers and sellers, which complicates the establishment of a fair market price through competitive bidding.

When your execution pathway narrows to a single dealer, the very mechanism of competitive [price discovery](https://prime.greeks.live/area/price-discovery/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is absent. This scenario moves the execution process away from the familiar terrain of lit, order-driven markets and into a realm governed by process, justification, and demonstrable diligence.

The regulatory framework, particularly as outlined by [FINRA Rule 5310](https://prime.greeks.live/area/finra-rule-5310/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), does not presuppose that all orders must be exposed to multiple counterparties. Instead, it mandates a state of “reasonable diligence” to ensure the resulting price is as favorable as possible under the prevailing market conditions. The system acknowledges that for certain assets, particularly in debt markets or for large, complex block trades, the universe of potential counterparties may be exceptionally small, sometimes shrinking to a single institution with a unique axe or warehousing capability.

In these instances, the concept of best execution transforms. It becomes a function of a robust, documented, and [defensible process](https://prime.greeks.live/area/defensible-process/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) rather than the simple outcome of a multi-dealer auction.

> A firm’s ability to prove best execution in a single-dealer trade hinges on the quality of its documented diligence, not the number of quotes received.

This operational reality demands a sophisticated internal framework. The firm’s obligation shifts from sourcing multiple live quotes to conducting a rigorous [pre-trade analysis](https://prime.greeks.live/area/pre-trade-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that justifies the single-counterparty approach. This involves a deep understanding of the security in question, an awareness of which market participants have historically shown interest, and a qualitative assessment of the risks associated with broader market exposure. For example, shopping a large, illiquid block trade to multiple dealers could create [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), signaling the seller’s intent to the wider market and causing adverse price movement before the trade is ever executed.

In such a case, discreetly negotiating with a single, trusted counterparty may be the superior strategy for protecting the client’s interests and achieving a favorable outcome. The burden of proof, therefore, rests on the firm’s ability to articulate and evidence this strategic choice.

## Strategy

A successful strategy for executing an illiquid trade with one counterparty is built upon a foundation of procedural integrity. The goal is to construct a clear, auditable trail that demonstrates how the final execution price, even without direct competition, was the most favorable outcome achievable. This requires a disciplined, multi-stage approach that begins long before the trade is placed and continues well after it is settled.

## The Framework for Defensible Execution

The core of the strategy is to create a decision-making framework that is both logical and evidence-based. This framework must be codified in the firm’s written policies and procedures, as mandated by regulators. It should explicitly acknowledge that for certain securities, a single-dealer negotiation is a valid execution method. The policy must then detail the specific conditions under which this method is appropriate and the exact steps a trader must take to satisfy their best execution duty.

This involves creating a system that prospectively identifies securities likely to trade bilaterally and retrospectively analyzes the quality of those executions. The strategy is to treat the absence of competition as a risk factor that must be mitigated through enhanced internal diligence. This means the firm’s own processes must supply the rigor that the market itself cannot provide.

## What Is the Role of Pre Trade Analysis?

Pre-trade analysis is the most critical stage in a single-counterparty strategy. It is here that the justification for the trade is built. The analysis must be documented and preserved, forming the primary evidence of the firm’s diligence. This process involves several key activities:

- **Market Intelligence** This involves gathering all available data on the security, however scarce. This includes recent trade prints, indicative quotes from pricing services, and any relevant market color from sales coverage. The objective is to establish a reasonable price range before ever approaching the counterparty.

- **Counterparty Assessment** The firm must document why a particular counterparty was chosen. This could be based on historical trading activity, a known specialization in the asset class, or specific intelligence that the dealer has a natural offsetting interest (an “axe”). This assessment demonstrates that the choice was deliberate and informed.

- **Risk Analysis** The trader must weigh the risk of information leakage against the potential benefit of wider price discovery. For a large, sensitive order, documenting the conclusion that a single-dealer approach minimizes market impact is a powerful piece of evidence. SIFMA has noted that contacting multiple dealers can sometimes send signals that work to the detriment of the customer’s order.

> In the absence of multiple quotes, the quality of the pre-trade documentation becomes the primary benchmark for execution quality.

The table below compares different liquidity sourcing methods for a hypothetical illiquid corporate bond, illustrating the strategic trade-offs involved.

| Execution Method | Information Leakage Risk | Potential for Price Improvement | Certainty of Execution | Ideal Scenario |
| --- | --- | --- | --- | --- |
| Single-Dealer RFQ | Low | Low to Moderate | High | Large, sensitive order where market impact is the primary concern. |
| Multi-Dealer RFQ | Moderate | High | High | Standard block trade with several known active dealers in the name. |
| All-to-All Platform | High | Moderate to High | Low to Moderate | Smaller, less sensitive order where broad exposure is acceptable. |
| Lit Exchange Order Book | Very High | Varies | Low | Highly liquid securities; unsuitable for illiquid assets. |

## Structuring the Bilateral Negotiation

Even when dealing with a single counterparty, the interaction should be formalized. Using a Request for Quote (RFQ) protocol, even with an audience of one, structures the negotiation and creates a formal record. The firm should provide a clear indication of size and, potentially, a price level based on its pre-trade analysis.

The counterparty’s response, the resulting negotiation, and the final agreed-upon price should all be logged electronically. This process transforms an informal conversation into a structured, auditable execution event, providing a clear narrative for compliance and regulatory review.

## Execution

The execution phase translates the firm’s strategy into a set of concrete, repeatable actions. For a single-counterparty trade, the focus of execution is on process integrity, meticulous record-keeping, and robust post-trade validation. The objective is to generate a comprehensive audit trail that can withstand internal and external scrutiny, proving that the duty of best execution was fulfilled despite the structural limitations of the trade.

## The Operational Workflow for a Single Dealer Trade

A compliant execution workflow for a bilateral trade is systematic and auditable. Each step must be logged within the firm’s Order Management System (OMS) or a similar system of record. This process ensures that every decision point is captured and justified.

- **Pre-Trade Documentation** Before any market contact, the trader or portfolio manager must create a pre-trade ticket. This digital or physical record should include the security identifier, desired quantity, and a summary of the pre-trade analysis. It must explicitly state the rationale for selecting a single-counterparty negotiation, referencing factors like market impact concerns, the uniqueness of the counterparty’s liquidity, or the absence of other viable dealers.

- **Formal Quote Solicitation** The trader initiates a formal, recorded communication with the selected dealer. This should be done via a recorded phone line or a secure electronic messaging platform that is archived. The request should be specific, and the dealer’s response ▴ the quote ▴ must be recorded with a precise timestamp.

- **Execution and Price Justification** If the quote is deemed acceptable based on the pre-trade price analysis, the trade is executed. The trader must then append a note to the trade record, attesting that the execution price is considered fair and reasonable under the prevailing market conditions. If the price deviates significantly from the pre-trade estimate, a more detailed justification is required.

- **Post-Trade Allocation and Confirmation** The trade is allocated to the appropriate client accounts, and a confirmation is sent. The details on the confirmation must match the execution record precisely. This step ensures transparency for the end client.

- **Supervisory Review** A designated principal or supervisor must review the trade, typically at the end of the day. This review involves examining the pre-trade documentation, the execution record, and the trader’s justification. The supervisor’s sign-off provides a second layer of validation and oversight.

## How Is Quantitative Benchmarking Applied in a Data Scarce Environment?

This is the central challenge in proving best execution for [illiquid assets](https://prime.greeks.live/area/illiquid-assets/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Without a vibrant public market, standard benchmarks like Volume-Weighted Average Price (VWAP) are often irrelevant or unavailable. Therefore, firms must construct appropriate benchmarks and perform a rigorous [Trade Cost Analysis](https://prime.greeks.live/area/trade-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) using the data they can access.

> Effective TCA for illiquid assets relies on a mosaic of data points to construct a fair value estimate where no single market price exists.

The table below provides an example of a post-trade TCA report for a series of illiquid bond trades. It demonstrates how a firm can use evaluated pricing and qualitative factors to assess execution quality.

| Trade ID | Asset (CUSIP) | Side | Quantity | Execution Price | Evaluated Price (End of Day) | Slippage vs. Eval (bps) | Qualitative Justification Code |
| --- | --- | --- | --- | --- | --- | --- | --- |
| 77A5-1 | 12345ZXY9 | Sell | 10,000,000 | 98.50 | 98.65 | -15.0 | IMPACT-MIN |
| 77A5-2 | 98765ABC1 | Buy | 5,000,000 | 101.25 | 101.10 | +15.0 | AXE-ONLY |
| 77A5-3 | 45678DEF2 | Sell | 2,500,000 | 45.75 | 45.50 | +25.0 | CLIENT-DIR |
| 77A5-4 | 65789GHI3 | Buy | 7,500,000 | 100.05 | 100.00 | +5.0 | AXE-ONLY |

In this example, the “[Evaluated Price](https://prime.greeks.live/area/evaluated-price/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” is a fair value estimate provided by a third-party pricing service. The “Qualitative Justification Code” provides crucial context. For instance, trade 77A5-1 was executed slightly below the evaluated price, but the justification “IMPACT-MIN” indicates the primary goal was to sell a large block with minimal market disruption, a valid best execution consideration. Trade 77A5-2 was executed above the evaluated price, but the code “AXE-ONLY” documents that this was the only available counterparty with a natural buying interest, justifying the price paid.

## Documenting the Decision Making Process

A formal justification log is the ultimate output of the execution process. This log serves as the definitive record for compliance and regulators, demonstrating a systematic and thoughtful approach. It connects every stage of the workflow into a coherent narrative.

- **Trade Rationale** A clear statement of the investment objective and the reason for the trade.

- **Counterparties Considered** Even if only one is contacted, the log should note which other dealers were considered and why they were not approached (e.g. “History of information leakage,” “No known activity in this asset”).

- **Benchmark Selection** The log must state which benchmark was used for post-trade analysis (e.g. “Prior day’s evaluated price,” “Recent comparable trade print”) and why it was deemed appropriate.

- **Compliance Review** The log should have a field for a compliance officer or supervisor to formally sign off, indicating that they have reviewed the trade and found the process and justification to be satisfactory.

By executing trades within this highly structured and documented system, a firm can confidently assert that it has met its best execution obligations, even when faced with the inherent challenges of an illiquid, single-counterparty transaction.

## Reflection

The analysis of best execution in illiquid, single-counterparty scenarios moves our focus from the trading floor to the system’s architecture. It reveals that superior execution is a product of superior design. The integrity of a single trade is a direct reflection of the integrity of the operational framework that surrounds it. The documentation, the pre-trade analytics, the post-trade review ▴ these are the essential components of that system.

Consider your own firm’s operational architecture. Does it treat best execution as a passive result to be measured, or as an active process to be engineered? A robust system anticipates the challenge of illiquidity.

It provides its operators with the tools and protocols necessary to navigate data-scarce environments with confidence and discipline. The ultimate advantage is found in building a framework where a defensible process is the default outcome, ensuring that every action, especially in the market’s most opaque corners, reinforces the firm’s commitment to its fiduciary duty.
