## From Handshake to Hard Data the New Anatomy of RFQ

The Markets in Financial Instruments Directive II (MiFID II) did not merely introduce a new layer of rules onto the [Request for Quote](https://prime.greeks.live/area/request-for-quote/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (RFQ) protocol; it fundamentally re-engineered its operational DNA. For decades, the RFQ process, particularly in less liquid markets like corporate bonds and over-the-counter (OTC) derivatives, operated on a foundation of relationships and trust. An investment manager would discreetly solicit quotes from a small circle of trusted [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and execution was often a matter of professional judgment. MiFID II challenged this paradigm by introducing a non-negotiable principle ▴ all sufficient steps must be taken to achieve the best possible result for the client, and critically, this process must be demonstrable and auditable.

This mandate transformed the [RFQ](https://prime.greeks.live/area/rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) from a private conversation into a structured, data-centric event. The regulation effectively injected a new nervous system of accountability into the process. The focus shifted from the simple act of getting a price to a rigorous, evidence-based methodology for price discovery and execution. Every decision, from which counterparties to include in the RFQ to the final execution price, became subject to scrutiny against a set of defined [execution factors](https://prime.greeks.live/area/execution-factors/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) ▴ price, costs, speed, likelihood of execution and settlement, size, and nature of the order.

This systemic change meant that the informal “rolodex” of dealers had to be replaced, or at least augmented, by a quantitative and qualitative framework for [counterparty selection](https://prime.greeks.live/area/counterparty-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The implicit trust of the old model was now required to be made explicit through data.

> The core influence of MiFID II was the conversion of the RFQ from a qualitative, relationship-based interaction into a quantitative, evidence-based process demanding a robust data architecture for compliance and justification.

## The Execution Factors a New Grammar for Trading

At the heart of MiFID II’s influence is the codification of “[best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” into a multi-faceted concept. The regulation compels firms to move beyond the singular pursuit of the best price. For an RFQ, this means a firm must have a clear, documented policy that explains the relative importance of each execution factor for different asset classes and client types. For a large, illiquid block trade, for instance, the likelihood of execution and minimizing [market impact](https://prime.greeks.live/area/market-impact/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) might outweigh the raw price when compared to a small, liquid trade.

The [RFQ protocol](https://prime.greeks.live/area/rfq-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), with its ability to discreetly source liquidity from selected providers, remains a vital tool in this context. It allows firms to manage the [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that could occur on a more transparent, order-driven market.

However, [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, the choice to use an RFQ, and the manner in which it is conducted, must be justified. A firm must be able to demonstrate why an RFQ was a better method than, for example, placing an order on a lit exchange or an MTF (Multilateral Trading Facility). This justification must be rooted in the execution factors. The electronic audit trail created by modern RFQ platforms has become an essential component of this compliance framework, capturing the [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), timestamps, and the final execution details.

This data provides the raw material for the post-trade analysis required to prove that the best execution obligation was met. The regulation, therefore, creates a powerful incentive to electronify RFQ workflows, moving them from phone-based interactions to on-venue, reportable events on platforms like Organised Trading Facilities (OTFs) or through Systematic Internalisers (SIs).

## Systematic Counterparty Selection and Venue Analysis

In the post-[MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) environment, a firm’s strategy for utilizing the RFQ protocol must be deliberate and systematic. The days of relying on an informal list of preferred dealers are over. A compliant and effective strategy begins with the formalization of the counterparty selection process. This involves creating a dynamic and data-driven framework for evaluating potential liquidity providers.

This framework must extend beyond historical pricing competitiveness to include the full range of MiFID II execution factors. Firms must develop scorecards that rank counterparties on metrics such as response times, fill rates, and post-trade [settlement efficiency](https://prime.greeks.live/area/settlement-efficiency/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This quantitative approach ensures that the selection of dealers for an RFQ is not arbitrary but is instead a defensible part of the best execution process.

Furthermore, the strategy must encompass a sophisticated analysis of execution venues. MiFID II introduced new types of trading venues, such as Organised Trading Facilities (OTFs), and formalized the role of Systematic Internalisers (SIs). An [OTF](https://prime.greeks.live/area/otf/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), for instance, provides a regulated environment for discretionary trading, making it a suitable venue for RFQ protocols in non-equity instruments. An [SI](https://prime.greeks.live/area/si/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is an investment firm that deals on its own account by executing client orders outside a regulated market or an MTF.

When a firm sends an RFQ to a bank acting as an SI, it is interacting with a specific type of execution venue with its own set of transparency and reporting obligations. A robust strategy, therefore, involves defining which types of orders are best suited for RFQs on an OTF versus those directed to SIs or other liquidity providers. This decision will depend on the asset class, the size of the order, and the client’s specific instructions.

The table below outlines a strategic framework for aligning order characteristics with venue choice in an RFQ-centric workflow under MiFID II.

| Order Characteristic | Primary Execution Factor | Optimal RFQ Venue/Method | Strategic Rationale |
| --- | --- | --- | --- |
| Large-in-Scale (LIS) Corporate Bond | Likelihood of Execution / Market Impact | RFQ to multiple dealers, including SIs and on an OTF | Minimizes information leakage and sources deep liquidity from dedicated providers. The OTF provides a regulated framework for discretionary execution. |
| Standardized Interest Rate Swap | Price / Cost | Competitive RFQ to a broad panel of SIs and other LPs | Maximizes price competition for liquid instruments where market impact is less of a concern. |
| Illiquid, Complex Derivative | Likelihood of Execution / Certainty of Settlement | Targeted RFQ to a small number of specialist dealers | Focuses on counterparties with proven expertise and balance sheet capacity for the specific instrument, prioritizing successful execution over broad price competition. |
| Small, Liquid Equity Block | Speed / Price | RFQ to SIs or execution via SOR to lit markets | For smaller sizes, the speed and efficiency of an SI or the price discovery of a central limit order book may be superior to a traditional multi-dealer RFQ. |

## The Centrality of Data in Demonstrating Compliance

A core pillar of any MiFID II-compliant RFQ strategy is the generation, capture, and analysis of data. The regulation’s mandate for firms to “take all sufficient steps” to achieve best execution necessitates a robust audit trail. This has profound implications for the technology and workflows surrounding the RFQ process. Strategically, firms must invest in systems that can seamlessly integrate [pre-trade analysis](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), real-time execution data, and post-trade [transaction cost analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA).

- **Pre-Trade Analysis** ▴ Before an RFQ is even initiated, firms should have a mechanism to establish a [fair value estimate](https://prime.greeks.live/area/fair-value-estimate/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for the instrument. This could involve using data from consolidated tape providers, evaluated pricing services, or internal models. This [pre-trade benchmark](https://prime.greeks.live/area/pre-trade-benchmark/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is critical for assessing the quality of the quotes received.

- **Execution Data Capture** ▴ The RFQ platform or [execution management system](https://prime.greeks.live/area/execution-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (EMS) must capture every aspect of the process. This includes the list of dealers queried, the exact time quotes were requested and received, the prices and sizes of all quotes, and the final execution details. This granular data is the evidence required to reconstruct and justify the trading decision.

- **Post-Trade [TCA](https://prime.greeks.live/area/tca/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)** ▴ After the trade is executed, it must be analyzed against various benchmarks to assess its quality. For an RFQ, this would involve comparing the execution price to the pre-trade fair value estimate, the other quotes received (the “book of available liquidity”), and potentially market benchmarks like the arrival price or a volume-weighted average price (VWAP) if applicable. This analysis forms the backbone of the reports provided to clients and regulators.

The requirement to publish annual reports on the top five execution venues used (as stipulated by [RTS 28](https://prime.greeks.live/area/rts-28/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)) further cements the strategic importance of data. While the stringency of these reporting requirements has been subject to review, the underlying principle of transparency remains. Firms must have a data architecture that can accurately track execution volumes and quality across all venues, including SIs and OTFs used for RFQ-based trading. This data is not just for compliance; a forward-thinking strategy uses this information to refine the counterparty selection process and optimize execution policies over time.

## The Operational Playbook a MiFID II Compliant RFQ Workflow

Executing an RFQ under MiFID II is a disciplined, multi-stage process that must be embedded in a firm’s operational procedures. It transforms a simple request for a price into a structured, auditable event. The following playbook outlines the critical steps for a compliant workflow.

- **Order Receipt and Pre-Trade Analysis** ▴ 

<li>**a. Characterize the Order** ▴ Upon receiving a client order, the first step is to classify it based on the instrument type, size, liquidity profile, and any specific client instructions. This characterization determines the relative importance of the MiFID II execution factors.

- **b. Justify the RFQ Protocol** ▴ The decision to use an RFQ must be documented. For an illiquid bond, the justification might be that an RFQ is the only viable method to source liquidity without causing adverse market impact. For a liquid instrument, the justification may be to ensure competitive pricing from multiple SIs.

- **c. Establish a Benchmark Price** ▴ Before initiating the RFQ, an independent, time-stamped fair value estimate must be established. This benchmark is the primary reference point for evaluating the quality of the quotes that will be received.

</li>
- **Counterparty Selection and RFQ Initiation** ▴ 

<li>**a. Consult the Counterparty Scorecard** ▴ Using a quantitative scorecard (see table below), select a list of appropriate liquidity providers. The number of counterparties should be sufficient to ensure competitive tension but not so large as to risk information leakage. A common practice is to request quotes from three to five dealers.

- **b. Initiate the RFQ Electronically** ▴ The RFQ should be sent to all selected counterparties simultaneously through an electronic system. This ensures a fair process and creates a clear, time-stamped [audit trail](https://prime.greeks.live/area/audit-trail/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) of when the request was sent.

</li>
- **Quote Management and Execution** ▴ 

<li>**a. Monitor Responses** ▴ The system must track all incoming quotes, including price, size, and the time each quote is received. Any declines to quote should also be logged.

- **b. Evaluate Against Benchmarks** ▴ As quotes arrive, they are compared in real-time against the pre-trade benchmark price and against each other. The full set of received quotes constitutes the “best available price” at that moment.

- **c. Execute and Document** ▴ The trade is executed with the counterparty providing the best result, considering all relevant execution factors. The final decision, especially if not based solely on the best price, must be documented with a clear justification (e.g. “Executed with Counterparty B, despite a marginally wider price than Counterparty A, due to a significantly larger available size, which was necessary to fill the client’s full order and minimize the risk of having to execute a second block.”).

</li>
- **Post-Trade Reporting and Analysis** ▴ 

<li>**a. Transaction Reporting** ▴ The executed trade is reported to the relevant regulatory authorities as required by MiFIR transaction reporting rules.

- **b. Conduct TCA** ▴ A formal [Transaction Cost](https://prime.greeks.live/area/transaction-cost/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Analysis report is generated, comparing the execution against the pre-trade benchmark, the other quotes received, and other relevant [market data](https://prime.greeks.live/area/market-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This report is the primary evidence of best execution.

- **c. Update Counterparty Scorecards** ▴ The performance of all queried counterparties (including response times and competitiveness) is used to update the quantitative scorecards, ensuring the system is dynamic and self-improving.

## Quantitative Modeling and Data Analysis

The effective execution of this playbook relies on a robust quantitative framework. The following tables provide examples of the data models required to support a MiFID II-compliant [RFQ process](https://prime.greeks.live/area/rfq-process/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).

## Pre-Trade RFQ Counterparty Scorecard

This table illustrates a model for selecting counterparties for an RFQ for a specific asset class (e.g. Euro-denominated corporate bonds). The weights are determined by the firm’s [execution policy](https://prime.greeks.live/area/execution-policy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which prioritizes certain factors over others.

| Counterparty | Historical Price Competitiveness (40% Weight) | Average Response Time (s) (20% Weight) | Likelihood of Execution (Fill Ratio) (30% Weight) | Settlement Efficiency (10% Weight) | Weighted Score | Rank |
| --- | --- | --- | --- | --- | --- | --- |
| Dealer A | 9.5 | 1.5 | 98% | 99.9% | 9.39 | 1 |
| Dealer B | 9.2 | 2.1 | 95% | 99.8% | 8.93 | 2 |
| Dealer C | 8.8 | 3.5 | 99% | 99.5% | 8.87 | 3 |
| Dealer D | 9.4 | 5.0 | 85% | 99.7% | 8.32 | 4 |
| Dealer E | 8.5 | 2.5 | 88% | 98.0% | 8.22 | 5 |

## Predictive Scenario Analysis a Large, Illiquid Bond Trade

Imagine a portfolio manager at a mid-sized asset management firm is tasked with selling a €30 million position in a thinly traded bond issued by a non-benchmark industrial company. The market for this bond is opaque, with no continuous lit market pricing. This scenario represents a classic case where the RFQ protocol is essential, and where the MiFID II framework provides a clear, structured path to execution.

The process begins with the portfolio manager creating an order in the firm’s Execution [Management System](https://prime.greeks.live/question/what-is-the-relationship-between-an-order-management-system-and-an-execution-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (EMS). The EMS immediately flags the order’s characteristics ▴ illiquid, large-in-scale relative to average daily volume, and sensitive to information leakage. The firm’s pre-programmed best execution policy, designed for this type of instrument, automatically designates the RFQ protocol as the primary execution method. The justification is logged ▴ “Use of RFQ is necessary to source bespoke liquidity and prevent negative market impact associated with displaying a large sell order on a public venue.”

Next, the EMS performs its pre-trade analysis. It pulls the latest available composite pricing data from the firm’s market data provider, which suggests a current indicative mid-price of 98.75. This price is time-stamped and stored as the primary benchmark for the trade. The system then accesses the firm’s internal counterparty scorecard for European corporate bonds.

It analyzes the top ten ranked dealers based on a weighted model that, for this specific type of illiquid asset, heavily favors ‘Likelihood of Execution’ (45% weighting) and ‘Historical Price Competitiveness’ (35% weighting) over ‘Response Time’ (20% weighting). The system recommends sending the RFQ to the top four dealers ▴ a large international bank known for its strong credit trading desk, a regional dealer with a specific niche in industrials, and two other systematic internalisers who have shown consistent axes in similar securities.

The trader reviews and confirms the selection, and the EMS dispatches the RFQ to the four dealers simultaneously at 14:15:00 UTC. The request is for a firm, all-or-nothing bid for the full €30 million size. The responses begin to populate the execution blotter. Dealer 1 bids 98.60.

Dealer 2 declines to quote, citing no current interest. Dealer 3 bids 98.55. Dealer 4, the regional specialist, comes back with a bid of 98.62 after 45 seconds. The system highlights Dealer 4’s bid as the best price.

However, Dealer 1, whose bid was slightly lower, has a significantly higher settlement efficiency score on the firm’s scorecard (99.9% vs. Dealer 4’s 98.5%). The execution policy allows the trader to use this qualitative factor in their decision. The trader, valuing certainty of settlement in this illiquid instrument, adds a note to the order ▴ “Best price from Dealer 4 is 98.62.

Considering the illiquid nature of the security, the superior settlement record of Dealer 1 provides a significant qualitative benefit that justifies the 2 basis point price differential.” However, before executing, the trader decides to give Dealer 1 a chance to improve. A note is logged, and a message is sent. Dealer 1 revises their bid to 98.61. The trader now has a clear, documented rationale. They execute the full €30 million with Dealer 1 at 14:17:30 UTC.

The post-trade process is now automated. The execution details are sent for transaction reporting. The TCA module immediately generates a report. It shows the execution price of 98.61 against the pre-trade benchmark of 98.75 (a slippage of 14 basis points, which is within the expected tolerance for this security).

It also logs the other bids received (98.55 and 98.62), demonstrating that the execution was achieved at a competitive level within the available liquidity. The report explicitly includes the trader’s note regarding the consideration of settlement efficiency. This complete data record, from the initial justification for using RFQ to the final TCA report, forms a complete and defensible audit trail, fulfilling the firm’s obligations under MiFID II. The data from this trade simultaneously updates the counterparty scorecards, noting Dealer 4’s strong pricing and Dealer 1’s responsiveness, refining the system for the next trade.

## System Integration and Technological Architecture

A MiFID II-compliant RFQ process cannot exist in a vacuum. It requires a sophisticated and integrated technological architecture. At the center of this system is the Execution Management System (EMS) or Order Management System (OMS). This platform must be the single source of truth for the entire lifecycle of an order.

The required integrations include:

- **Market Data Feeds** ▴ The EMS must be connected to real-time and historical market data providers to power the pre-trade analysis and TCA. This includes data from regulated markets, MTFs, OTFs, and consolidated tape providers.

- **[FIX Protocol](https://prime.greeks.live/area/fix-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Connectivity** ▴ The Financial Information eXchange (FIX) protocol is the industry standard for electronic trading communication. The EMS must use specific FIX messages for the RFQ workflow. Key message types include QuoteRequest (R) to send the RFQ, QuoteResponse (AJ) to receive quotes back from dealers, and ExecutionReport (8) to confirm the final trade. The system must log every single one of these messages with precise timestamps.

- **Counterparty Network** ▴ The EMS needs to have established connectivity to a wide network of liquidity providers, including banks acting as SIs and dedicated OTF platforms.

- **Data Warehouse and Analytics Engine** ▴ All data generated throughout the process ▴ order details, pre-trade benchmarks, every quote message, execution reports, and post-trade analysis ▴ must be captured and stored in a structured data warehouse. This repository is the foundation for all regulatory reporting (such as the now-suspended [RTS 27](https://prime.greeks.live/area/rts-27/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)/28 reports), internal compliance reviews, and strategic analysis of execution quality.

This integrated architecture ensures that the data flows seamlessly from one stage of the process to the next, creating a coherent and unbroken audit trail. It is this system-level integration that transforms the MiFID II best execution requirements from a regulatory burden into a data-driven framework for achieving and proving superior execution.

## From Mandate to Mechanism

The implementation of MiFID II has fundamentally altered the calculus of institutional trading. The regulation’s influence on the RFQ protocol serves as a primary example of this systemic shift. The framework compels market participants to move beyond a compliance-oriented mindset and toward the construction of a sophisticated operational mechanism. The true question posed by the regulation is not “Are we compliant?” but rather “Is our execution framework intelligent?”

The data-driven requirements for best execution have created a new currency in financial markets ▴ demonstrable quality. The ability to capture, analyze, and act upon execution data is now as critical as the ability to source liquidity. This presents a profound opportunity. The same data architecture built to satisfy regulatory obligations can be leveraged to generate a persistent competitive advantage.

The detailed counterparty scorecards, the granular transaction [cost analysis](https://prime.greeks.live/area/cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and the systematic evaluation of execution venues are not merely compliance artifacts; they are the core components of a learning system. They provide the feedback loop necessary to refine strategy, optimize relationships, and ultimately, achieve a superior level of capital efficiency for clients.

Therefore, viewing MiFID II solely through the lens of a regulatory constraint is a strategic error. The directive provides the blueprint for a more robust, transparent, and quantifiable approach to trading. The challenge for institutions is to build the operational engine capable of translating this blueprint into tangible performance. The ultimate differentiator will be the ability to transform the vast streams of mandated data into actionable intelligence, turning a regulatory requirement into a cornerstone of the firm’s execution philosophy.
