## Concept

The implementation of the Markets in Financial Instruments Directive II (MiFID II) represents a fundamental re-architecting of the European financial markets’ operational blueprint. For participants in the over-the-counter (OTC) [fixed income](https://prime.greeks.live/area/fixed-income/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and derivatives markets, the directive’s impact on 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 was immediate and systemic. The core change was a mandated shift from an environment often characterized by informal, bilateral negotiations to a structured, transparent, and auditable electronic framework. The regulation imposed a new layer of data-driven accountability onto a market traditionally reliant on dealer-client relationships.

At the heart of this transformation is the directive’s stringent approach to [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and transparency. MiFID II requires investment firms to take all sufficient steps to obtain the best possible result for their clients, considering price, costs, speed, likelihood of execution, and other relevant factors. This obligation necessitates a demonstrable and evidence-based audit trail for every trade. The traditional, voice-based [RFQ process](https://prime.greeks.live/area/rfq-process/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), with its inherent lack of a standardized data capture mechanism, became operationally untenable under this new regime.

Consequently, [electronic RFQ](https://prime.greeks.live/area/electronic-rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) platforms became the default infrastructure for demonstrating compliance. These platforms provide a systematic way to solicit quotes from multiple dealers, record response times, and archive all relevant data points, thereby creating the necessary evidence for best execution policies.

> MiFID II systematically transitioned RFQ protocols from relationship-based voice trading to auditable electronic systems to enforce best execution standards.

Furthermore, the directive introduced the concept of the [Systematic Internaliser](https://prime.greeks.live/area/systematic-internaliser/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (SI). An SI is an investment firm that, on an organized, frequent, systematic, and substantial basis, deals on its own account when executing client orders outside a regulated market or multilateral trading facility. When a dealer qualifies as an SI for a particular instrument, it incurs specific pre-trade transparency obligations. This means the SI must make public firm quotes for sizes up to a standard market size.

This requirement directly alters [dealer behavior](https://prime.greeks.live/area/dealer-behavior/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) within the [RFQ](https://prime.greeks.live/area/rfq/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) workflow. Dealers operating as SIs are incentivized to respond to RFQs electronically to efficiently manage and publish these quotes, further cementing the move away from voice trading. The regulation effectively created a new classification of market participant with defined obligations, forcing a structural change in how dealers manage their quoting infrastructure and interact with clients.

## Strategy

The regulatory architecture of [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) compelled both buy-side and sell-side firms to fundamentally overhaul their strategic approach to the RFQ process. The mandate for demonstrable best execution acted as a catalyst, transforming liquidity sourcing from a qualitative, relationship-driven art into a quantitative, data-centric science. This necessitated new strategies centered on technology adoption, data analysis, and a more dynamic approach to counterparty selection.

## The Shift to Multi Dealer Platforms

A primary strategic response from the buy-side was the accelerated adoption of multi-dealer [RFQ platforms](https://prime.greeks.live/area/rfq-platforms/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). These venues became the central hub for satisfying MiFID II’s requirements in a single, integrated workflow. Strategically, using such a platform allows an asset manager to achieve several objectives simultaneously. First, it provides a simple and effective method for meeting the best execution obligation of soliciting multiple quotes.

Second, it creates a comprehensive, time-stamped electronic audit trail for every transaction, simplifying compliance and reporting. Third, it broadens access to liquidity beyond a firm’s traditional dealer relationships, potentially improving pricing outcomes. Dealer behavior adapted in response; sell-side firms recognized that to receive client flow, they needed to be technologically integrated with these dominant platforms and develop algorithmic pricing capabilities to respond to electronic inquiries competitively and at scale.

> The strategic imperative for MiFID II compliance drove the adoption of multi-dealer platforms, which in turn forced dealers to develop competitive electronic quoting capabilities.

## How Does Data Reshape Counterparty Management?

Post-MiFID II, dealer selection became a more analytical process. Buy-side trading desks are now equipped with vast amounts of data generated by electronic RFQ platforms. This data allows for a quantitative evaluation of dealer performance based on metrics that were previously difficult to track systematically. These metrics include:

- **Hit Rate** The percentage of times a dealer wins a trade when they provide a quote.

- **Response Time** The speed at which a dealer responds to an RFQ.

- **Price Competitiveness** The spread of a dealer’s quote relative to the best quote received.

- **Post-Trade Performance** Analysis of any price slippage or issues after the trade is executed.

This data-driven approach allows buy-side firms to build a more dynamic and meritocratic dealer panel. Underperforming dealers can be identified and potentially replaced, while high-performing dealers can be rewarded with more flow. For dealers, this means that providing consistently competitive quotes and reliable execution is paramount. The relationship component remains important, particularly for complex or illiquid instruments, but it is now supplemented and validated by quantitative performance data.

## Pre-MiFID II versus Post-MiFID II RFQ Strategy

The table below outlines the strategic evolution of the RFQ process, highlighting the operational and behavioral shifts driven by the regulation.

| Strategic Element | Pre-MiFID II Approach | Post-MiFID II Approach |
| --- | --- | --- |
| Execution Method | Primarily voice-based (telephone) and chat messages. | Predominantly electronic via multi-dealer platforms. |
| Dealer Selection | Based on established relationships and perceived expertise. | Data-driven, based on quantitative metrics (hit rate, pricing). |
| Best Execution | A policy principle, with proof being largely qualitative. | A strict regulatory requirement with a burden of proof. |
| Audit Trail | Manual, inconsistent, and difficult to reconstruct. | Automated, comprehensive, and electronically stored. |
| Dealer Incentive | Maintain relationships to see client flow. | Provide competitive electronic quotes and invest in technology. |
| Market Transparency | Low, with price discovery concentrated among a few players. | Increased, with pre- and post-trade data more widely available. |

## Execution

The execution of an RFQ in a MiFID II environment is a precise, technology-dependent process. It requires a robust operational framework capable of satisfying complex regulatory demands while pursuing the ultimate goal of efficient price discovery and minimal information leakage. Success in this environment is a function of system integration, rigorous data analysis, and a clear, repeatable operational playbook.

## The Operational Playbook for a Compliant RFQ

Executing a trade via RFQ under MiFID II involves a series of deliberate steps designed to ensure compliance and achieve optimal execution. The following playbook outlines a best-practice workflow for a buy-side trading desk.

- **Trade Initiation and Pre-Trade Analysis** The portfolio manager’s order is received by the trading desk’s [Order Management System](https://prime.greeks.live/area/order-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (OMS). The trader analyzes the order’s characteristics, specifically its size relative to the MiFID II Large-in-Scale (LIS) and Size-Specific-to-Instrument (SSTI) thresholds. This initial classification determines the extent of pre-trade transparency obligations and influences the execution strategy.

- **Counterparty Selection** Using the firm’s [Execution Management System](https://prime.greeks.live/area/execution-management-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (EMS), which contains historical performance data, the trader selects a list of dealers to include in the RFQ. This selection is based on quantitative factors such as historical response rates, pricing competitiveness for similar instruments, and qualitative factors like the dealer’s known specialization in that asset class. A minimum of three dealers is standard practice to demonstrate a competitive process.

- **Electronic RFQ Submission** The RFQ is submitted electronically through a multi-dealer platform or a direct API connection. The request includes the instrument identifier (e.g. ISIN), direction (buy/sell), and size. The system automatically records the submission time for each dealer.

- **Quote Monitoring and Evaluation** The trader monitors incoming quotes in real-time within the EMS. The system displays the prices and sizes from each responding dealer. The trader evaluates the quotes against pre-trade benchmarks, such as the composite price from a data provider, to assess their quality.

- **Execution and Allocation** The trader executes against the chosen dealer by clicking to trade on the platform. The execution time is automatically captured. The trade details are then sent back to the OMS for allocation across the relevant client accounts.

- **Post-Trade Data Capture and Reporting** All data related to the RFQ process is automatically archived. This includes the list of dealers queried, their response times, the quotes provided, the execution price and time, and the rationale for choosing the winning dealer. This data forms the basis for the firm’s quarterly RTS 28 best execution reports.

## Quantitative Modeling and Data 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 cornerstone of proving best execution in an RFQ workflow. By systematically analyzing trade data, firms can quantify their execution quality and demonstrate compliance to regulators. The table below presents a simplified TCA report for a series of corporate bond RFQs.

| Trade ID | ISIN | Notional (EUR) | Arrival Price | Execution Price | Best Quoted Price | Slippage (bps) |
| --- | --- | --- | --- | --- | --- | --- |
| T101 | XS1234567890 | 5,000,000 | 99.50 | 99.52 | 99.52 | -2.0 |
| T102 | FR0987654321 | 10,000,000 | 101.10 | 101.08 | 101.08 | +2.0 |
| T103 | DE1122334455 | 2,000,000 | 100.25 | 100.26 | 100.25 | -1.0 |

**Slippage Calculation** ▴ (Execution Price – Arrival Price) 10,000. A negative value indicates implementation cost for a buy order, while a positive value indicates a benefit. In this analysis, the ability to execute at the best quoted price (as in trades T101 and T102) is a key indicator of an effective RFQ process.

## What Is the Required Technological Architecture?

A compliant and efficient RFQ workflow is built upon a foundation of integrated technologies. The core components of this architecture include:

- **Order [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) (OMS)** The system of record for all orders and allocations. It serves as the starting point of the trade lifecycle.

- **Execution Management System (EMS)** The primary interface for the trader. The EMS must integrate pre-trade data, provide connectivity to multiple RFQ platforms, and display incoming quotes in a consolidated view. It is the engine for TCA and dealer performance analysis.

- **Connectivity and Protocols** The entire system relies on robust connectivity. This is typically achieved through APIs provided by the trading venues and the FIX (Financial Information eXchange) protocol. Specific FIX messages, such as QuoteRequest (R), QuoteResponse (S), and ExecutionReport (8), are the digital lifeblood of the electronic RFQ process, carrying information between the buy-side, the venue, and the sell-side in a standardized format.

- **Data Warehouse** A centralized repository for storing all trade-related data. This warehouse feeds the TCA engines and provides the raw data needed for generating regulatory reports like RTS 27 and RTS 28.

This integrated architecture ensures that data flows seamlessly from order inception to post-trade analysis, creating the robust, auditable, and data-rich environment that MiFID II demands. It transforms the RFQ from a simple communication tool into a sophisticated execution protocol embedded within a larger system of operational control.
