## Concept

The Markets in Financial Instruments Directive II (MiFID II) establishes a comprehensive regulatory framework designed to enhance transparency and investor protection across European Union financial markets. A central pillar of this regulation is the mandate for [investment firms](https://prime.greeks.live/area/investment-firms/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to achieve the best possible result for their clients, an obligation commonly known as “[best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).” This requirement compels firms to take all sufficient steps to obtain the optimal outcome, considering a range of factors that extend beyond mere price. The directive explicitly includes costs, speed, likelihood of execution and settlement, order size, and any other relevant consideration. The regulation’s application is broad, covering all financial instruments, including those traded over-the-counter (OTC), and applies to various trading models.

Within this rigorous environment, the Request for Quote (RFQ) protocol presents a unique operational dynamic. The RFQ is a long-established execution mechanism, particularly prevalent in markets for less liquid assets like certain bonds and derivatives. It allows a firm to solicit competitive, binding quotes from a select group of [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for a specific trade. This controlled, bilateral price discovery process is engineered to source liquidity while minimizing the potential for adverse market impact and [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that can occur when a large order is exposed to a public forum.

The interaction between the discreet nature of the [RFQ protocol](https://prime.greeks.live/area/rfq-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and the transparency-focused objectives of MiFID II creates a complex compliance challenge. Firms must reconcile the use of a targeted [liquidity sourcing](https://prime.greeks.live/area/liquidity-sourcing/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) tool with a regulatory mandate for broad market consideration and demonstrable fairness in execution.

> The core challenge lies in embedding a bilateral trading protocol within a regulatory system that prioritizes multilateral transparency and competition.

## What Are the Core Tenets of MiFID II Best Execution?

The best execution obligation [under MiFID](https://prime.greeks.live/question/what-are-the-operational-consequences-of-misreporting-under-mifid-ii-versus-a-reporting-failure-under-emir/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) II is a significant evolution from its predecessor. The directive moves the standard from “all reasonable steps” to “all sufficient steps,” signaling a higher bar for compliance and requiring a more robust and evidence-based approach from investment firms. The regulation mandates that firms establish and implement a detailed [order execution policy](https://prime.greeks.live/area/order-execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that outlines how they will achieve the best possible results for their clients. This policy must be clear, comprehensive, and readily understandable to clients.

The [execution factors](https://prime.greeks.live/area/execution-factors/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that firms must consider are multifaceted:

- **Price** ▴ The price at which the transaction is executed.

- **Costs** ▴ All expenses related to the execution, including explicit fees (exchange fees, broker commissions) and implicit costs ([market impact](https://prime.greeks.live/area/market-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)).

- **Speed** ▴ The velocity of execution from order inception to completion.

- **Likelihood of Execution and Settlement** ▴ The probability that the trade will be successfully completed and settled.

- **Size and Nature of the Order** ▴ The specific characteristics of the order, which may influence the choice of execution method or venue.

Firms are required to demonstrate not only that they have a policy but also that they consistently adhere to it. This necessitates rigorous monitoring, periodic review of execution arrangements, and the ability to provide detailed evidence to clients and regulators upon request. The introduction of new reporting requirements, such as the quarterly [RTS 27](https://prime.greeks.live/area/rts-27/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) reports from execution venues and annual [RTS 28](https://prime.greeks.live/area/rts-28/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) reports from investment firms detailing their top five execution venues, further solidifies the directive’s focus on transparency and accountability.

## The RFQ Protocol as a System Component

The RFQ protocol functions as a critical component within a firm’s broader execution architecture. It is explicitly recognized within the [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) framework as a valid trading protocol, with certain regulatory requirements tailored to its specific mechanics. Its primary utility is for transactions that are illiquid, large in size, or possess complex characteristics that make them unsuitable for execution on a [central limit order book](https://prime.greeks.live/area/central-limit-order-book/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (CLOB). In a CLOB environment, exposing a large order can trigger significant price slippage and alert other market participants to the trading intention, leading to adverse selection.

The [RFQ](https://prime.greeks.live/area/rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) system mitigates these risks by creating a controlled competitive environment. An investment firm (the liquidity taker) can send a request to a curated list of liquidity providers, who then return executable quotes. This process allows the firm to access “committed liquidity” for a specific size without broadcasting its interest to the entire market.

For many firms, the adoption of on-venue RFQ systems, such as those operated on a Multilateral Trading Facility (MTF) or [Organised Trading Facility](https://prime.greeks.live/area/organised-trading-facility/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ([OTF](https://prime.greeks.live/area/otf/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)), has been a direct response to MiFID II’s objective of moving OTC trading onto regulated platforms. This transition facilitates greater transparency and regulatory oversight while preserving the functional benefits of the RFQ mechanism.

## Strategy

Strategically integrating the RFQ protocol into a MiFID II compliant execution framework requires a deliberate and systematic approach. Investment firms must construct an [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that not only permits the use of RFQs but also clearly defines the specific circumstances under which this protocol is the optimal choice for achieving best execution. This involves a sophisticated understanding of [market microstructure](https://prime.greeks.live/area/market-microstructure/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), instrument characteristics, and the explicit criteria laid out by the regulation. The overarching strategy is one of justification and evidence; the firm must be able to prove that its decision to use an RFQ for a particular trade was consistent with its duty to secure the best possible outcome for its client.

A key element of this strategy is the “legitimate reliance test,” a concept carried forward from MiFID I. This test is particularly relevant when a firm acts as a principal in an [RFQ trade](https://prime.greeks.live/area/rfq-trade/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Best execution obligations apply where the client has a legitimate expectation that the firm will protect its interests. This reliance is assessed based on several factors, including which party initiates the transaction, prevailing market practices, and the relative price transparency of the instrument in question. A sophisticated firm will build its strategy around these principles, ensuring that its use of RFQs is confined to scenarios where it is demonstrably superior to other available execution methods.

## Comparative Analysis of Execution Protocols

To build a defensible execution strategy, firms must conduct a comparative analysis of different execution protocols against the MiFID II best execution factors. The decision to use an RFQ is a strategic choice that must be weighed against alternatives like direct execution on a CLOB, utilizing a dark pool, or engaging an algorithmic trading strategy. Each method offers a different balance of the key execution factors.

The table below provides a strategic comparison of common execution methods for a large, less-liquid bond trade, illustrating the rationale for selecting an RFQ protocol.

| Execution Factor | Central Limit Order Book (CLOB) | Dark Pool | Request for Quote (RFQ) on an OTF |
| --- | --- | --- | --- |
| Price | Potentially poor due to high slippage and market impact from displaying a large order. Price discovery is public but can move adversely. | Price is typically derived from a lit market reference price (e.g. midpoint). Potential for price improvement exists, but fill is not guaranteed. | Competitive pricing is achieved from multiple dealers responding to the request. The final price is negotiated within a controlled environment. |
| Costs (Implicit) | High potential for information leakage and adverse selection, leading to significant implicit costs. | Low information leakage pre-trade. However, the risk of interacting with predatory trading strategies can exist. | Minimized information leakage as the request is sent to a select group. This control reduces market impact costs. |
| Likelihood of Execution | Low for the full size of a large, illiquid order without causing significant market disruption. Partial fills are likely. | Uncertain. Dependent on finding a matching counterparty in the dark pool at a specific moment in time. | High, as liquidity providers return firm, executable quotes for the specified size, providing “committed liquidity.” |
| Speed of Execution | Can be slow if the order must be worked over time to manage market impact. Immediate execution of the full size is unlikely. | Execution speed is variable and depends on the availability of a matching order. | Execution can be very rapid once quotes are received and a counterparty is selected. The entire process is typically completed within minutes. |

## The Role of Transaction Cost Analysis

[Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) is the analytical engine that powers a firm’s best execution strategy. For RFQ-based trades, where pre-trade price transparency is limited compared to a lit [order book](https://prime.greeks.live/area/order-book/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), post-trade TCA becomes the primary mechanism for demonstrating compliance with MiFID II. It provides the quantitative evidence needed to validate the quality of the execution. A robust TCA framework allows a firm to measure its performance against relevant benchmarks and prove that the chosen RFQ strategy yielded a superior result compared to available alternatives.

> Effective TCA transforms the abstract obligation of best execution into a measurable and defensible outcome.

For an RFQ transaction, [TCA](https://prime.greeks.live/area/tca/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) would typically involve:

- **Benchmark Selection** ▴ Identifying an appropriate benchmark price against which to measure the execution. This could be the arrival price (the market price at the time the order was received), a volume-weighted average price (VWAP) over a specific period, or a proprietary model-based price.

- **Cost Decomposition** ▴ Breaking down the total cost of the trade into its constituent parts, including explicit commissions, fees, and implicit costs like market impact and timing risk.

- **Counterparty Analysis** ▴ Evaluating the quality of the quotes received from different liquidity providers over time. This data helps refine the list of counterparties for future RFQs and supports the firm’s due diligence process.

- **Alternative Strategy Simulation** ▴ Comparing the actual execution results of the RFQ with the simulated results of alternative strategies. For example, a TCA system could model the likely market impact if the same order had been placed on a CLOB, providing a quantitative justification for the use of the RFQ.

By systematically capturing and analyzing this data, a firm can move beyond simply having an execution policy to actively monitoring and improving its execution quality, thereby fulfilling the continuous oversight requirements of MiFID II.

## Execution

The execution of a trade via the RFQ protocol under MiFID II is a structured process governed by precise operational and data-capture requirements. Firms must design a technological and procedural architecture that ensures every RFQ trade is not only commercially effective but also fully compliant with the directive’s stringent rules on transparency, reporting, and record-keeping. The focus of execution shifts from merely finding a counterparty to creating a complete, auditable trail that substantiates the firm’s adherence to its best execution policy. This involves integrating the firm’s Order Management System (OMS) and Execution Management System (EMS) with on-venue RFQ platforms and internal data repositories.

A critical aspect of execution is the selection of counterparties. A firm’s execution policy must detail the criteria used to select liquidity providers for an RFQ. This process must be objective and regularly reviewed. Factors influencing counterparty selection include their historical pricing competitiveness, settlement reliability, and creditworthiness.

Under MiFID II, simply sending a request to a single dealer is insufficient to demonstrate best execution in most cases. The protocol necessitates soliciting quotes from multiple competing providers to ensure a competitive outcome, a process that must be logged and evidenced by the trading system.

## How Is an RFQ Workflow Operationally Managed?

The operational workflow for an RFQ trade is a sequence of discrete steps, each with its own compliance considerations. The process begins the moment a portfolio manager’s investment decision is translated into a client order.

- **1. Order Inception and Pre-Trade Analysis** ▴ The trader receives the order into the EMS. The system, guided by the firm’s execution policy logic, identifies the order as suitable for RFQ execution based on its size, the instrument’s liquidity profile, and prevailing market conditions. Pre-trade analysis involves assessing potential market impact and defining the objectives for the execution (e.g. prioritizing price over speed).

- **2. Counterparty Selection** ▴ The trader, using the EMS interface, selects a list of approved liquidity providers to include in the RFQ. This selection is guided by the firm’s policy and supported by quantitative data on counterparty performance. For RFQs conducted on an OTF, the venue’s rules will also govern this process.

- **3. Quote Solicitation and Management** ▴ The RFQ is dispatched electronically to the selected counterparties. The EMS aggregates the returning quotes in real-time, displaying them in a standardized format that allows for easy comparison. The system logs the time of the request and the time each quote is received, creating a crucial data trail.

- **4. Execution and Allocation** ▴ The trader selects the best quote based on the execution factors defined in the policy (typically price, but also considering settlement risk and other factors). The trade is executed, and the system automatically captures the execution time, price, and counterparty details. The execution is then allocated to the relevant client account(s).

- **5. Post-Trade Data Capture and Reporting** ▴ This is a critical final stage. The execution system must capture all data points required for regulatory reporting under MiFID II’s RTS 27 (for venues) and RTS 28 (for investment firms). This includes precise timestamps, venue identification, and details of the transaction. This data feeds directly into the firm’s TCA systems and its annual top-five venue reporting.

## Data Requirements for Regulatory Reporting

MiFID II introduced extensive data reporting obligations to enhance market transparency. When an RFQ is executed on a trading venue like an MTF or OTF, the venue is responsible for post-trade transparency reporting. However, the investment firm remains responsible for its own record-keeping and for its RTS 28 report. The data captured during the execution workflow is fundamental to meeting these obligations.

The following table outlines key data fields that a firm’s systems must capture for an RFQ trade to ensure compliance.

| Data Category | Specific Data Point | Compliance Purpose |
| --- | --- | --- |
| Timestamps | Order receipt time, RFQ submission time, quote receipt times, execution time. | Creates a precise audit trail of the execution lifecycle, essential for TCA and demonstrating timely execution. |
| Venue and Counterparty | Execution venue identifier (e.g. MIC code of the OTF), Legal Entity Identifier (LEI) of the chosen counterparty. | Fulfills RTS 28 reporting requirements and allows for analysis of execution quality by venue and counterparty. |
| Pricing Data | All quotes received (price and size), the executed price. | Provides evidence of a competitive process and is the core input for calculating price-based TCA metrics. |
| Instrument Details | International Securities Identification Number (ISIN). | Ensures accurate identification of the financial instrument for all regulatory reports. |
| Client and Order IDs | Unique identifiers for the client and the specific order. | Links the execution back to a specific client mandate, ensuring proper allocation and record-keeping. |

Ultimately, the successful execution of an RFQ strategy under MiFID II depends on the seamless integration of technology, procedure, and analytics. The architecture must be designed not only to achieve the best commercial outcome for a trade but also to produce an unassailable body of evidence that proves, quantitatively and qualitatively, that the firm has met its best execution obligations.

## Reflection

The integration of the RFQ protocol within the MiFID II framework is a testament to the regulation’s capacity to accommodate diverse market structures while pursuing its core objectives. The process reveals that compliance is an exercise in system design. It requires the construction of an operational architecture where commercial objectives and regulatory obligations are addressed concurrently, not sequentially. The data generated by this system does more than satisfy a reporting requirement; it becomes the raw material for strategic refinement, enabling a continuous feedback loop of performance analysis and process improvement.

Consider your own firm’s execution architecture. How does it balance the need for discreet liquidity sourcing with the principles of transparency and competition? Where are the data capture points in your workflow, and how is that information utilized to validate and enhance your execution strategy? The answers to these questions define the robustness of your compliance framework and, ultimately, your ability to deliver a superior and demonstrable outcome for your clients in a complex regulatory landscape.

The directive moves the standard from \"all reasonable steps\" to \"all sufficient steps,\" signaling a higher bar for compliance and requiring a more robust and evidence-based approach from investment firms. The regulation mandates that firms establish and implement a detailed order execution policy that outlines how they will achieve the best possible results for their clients. This policy must be clear, comprehensive, and readily understandable to clients."
