How Does MiFID II Influence the Use of RFQs in European Equity Markets?

Concept

The Markets in Financial Instruments Directive II (MiFID II) fundamentally recalibrated the operational dynamics of European equity markets, compelling a systemic evolution in how liquidity is sourced and how execution quality is defined and proven. For institutional participants, the regulation introduced a non-negotiable framework of transparency and accountability, particularly through its stringent best execution requirements. This created a new set of challenges within a market landscape that was simultaneously becoming more fragmented.

The directive’s core components, including the Share Trading Obligation (STO), the stringent caps on dark pool trading, and the detailed reporting mandates under RTS 27 and 28, collectively reshaped the environment. These measures effectively constrained traditional methods of executing large orders without market impact, pushing participants to seek compliant and efficient alternatives.

The Regulatory Drivers of Change

MiFID II’s primary objective was to increase transparency across European financial markets and strengthen investor protection. For equity markets, this translated into several key mandates that directly influenced trading protocols. The Double Volume Cap (DVC) mechanism, for instance, limited the amount of trading in a particular stock that could occur in dark pools, forcing a significant volume of transactions back into more transparent environments. This shift posed a considerable problem for executing large block trades, as the anonymity of dark pools was a primary tool for minimizing information leakage and market impact.

Consequently, market participants required new mechanisms to transact in size while adhering to the new regulatory constraints. The regulation also formalized the role of Systematic Internalisers (SIs), firms that trade on their own account by executing client orders outside of a regulated market. This created a new, vital source of liquidity but also added to the fragmentation of the market, making it more complex to identify the best possible execution outcome.

Best Execution as a Core Mandate

Perhaps the most impactful element of MiFID II was its elevation of the best execution requirement from a guiding principle to a detailed, enforceable obligation. Firms are now required to take all sufficient steps to obtain the best possible result for their clients, considering factors beyond just price, such as costs, speed, and likelihood of execution and settlement. This necessitates a robust, auditable process for every trade. The requirement to produce detailed reports (RTS 28) for clients on execution quality and venues used means that every decision within the trading workflow must be justifiable and documented.

This created a substantial operational and compliance burden, compelling firms to adopt technologies and protocols that could provide the necessary electronic audit trails and data capture to prove compliance. The quote solicitation protocol, with its inherent structure of requesting prices from multiple providers and recording the responses, emerged as a natural fit for this new, demanding environment.

Strategy

In response to the systemic pressures introduced by MiFID II, market participants developed new execution strategies where the Request for Quote (RFQ) protocol assumed a central role. The regulation transformed the RFQ from a mechanism primarily used in less liquid, voice-traded markets into a sophisticated electronic tool essential for navigating the complexities of the new equity landscape. This strategic adoption was driven by the protocol’s ability to address the dual challenges of accessing fragmented liquidity and demonstrating auditable best execution.

For institutional traders, the RFQ became a primary method for discovering liquidity for large-in-scale (LIS) orders that were now difficult to place in dark venues due to the DVCs. By allowing a buy-side trader to selectively solicit firm quotes from multiple liquidity providers, including banks and SIs, the RFQ process provides a structured and controlled method of price discovery while minimizing market impact.

The electronic RFQ mechanism offers a structured and compliant pathway for sourcing committed liquidity, enabling buy-side firms to efficiently manage execution while mitigating information leakage.

Adapting to a Fragmented Liquidity Landscape

MiFID II’s measures led to a significant redistribution of liquidity across various venue types, including lit exchanges, SIs, and new multilateral trading facilities (MTFs) offering periodic auctions. This fragmentation increased the complexity of sourcing liquidity. RFQ platforms became a critical strategic tool for aggregation, allowing traders to simultaneously access liquidity from multiple SIs and other providers through a single interface.

This approach streamlines the search for liquidity and provides a competitive pricing environment. The ability to send a quote request to a curated list of counterparties allows traders to balance the need for competitive tension with the imperative to control information leakage, a crucial consideration for large orders.

The Systematic Internaliser Connection

The formalization of SIs under MiFID II created a new and significant pool of principal liquidity. SIs are required to provide firm quotes on request for sizes up to standard market size. The RFQ protocol is the natural mechanism for interacting with SIs. A buy-side desk’s execution strategy increasingly involves integrating SIs into their RFQ workflows.

This allows them to tap into the unique liquidity offered by these firms while systematically capturing the data needed for best execution analysis. The table below outlines the strategic considerations for integrating different liquidity sources into an RFQ workflow post-MiFID II.

Demonstrating Best Execution through Process

A core strategic shift prompted by MiFID II was the focus on the execution process over just the outcome. The RFQ protocol provides a clear, repeatable, and auditable process. Every step, from the selection of counterparties to the final execution, is time-stamped and recorded electronically. This creates a rich dataset for each trade that can be used for Transaction Cost Analysis (TCA) and to populate the RTS 28 reports required by the regulation.

This inherent audit trail is a powerful strategic asset in a compliance-heavy environment. It allows firms to move beyond simply achieving a good price to definitively proving that they followed a rigorous process to achieve the best possible result for their clients. The ability to customize the list of recipients for each RFQ allows firms to implement sophisticated counterparty management strategies, directing flow to providers who have demonstrated high-quality execution in the past and systematically documenting these decisions.

Execution

The operational execution of a Request for Quote in the MiFID II era is a highly structured process, governed by the dual imperatives of efficiency and compliance. Modern Execution Management Systems (EMS) and Order Management Systems (OMS) have integrated RFQ functionalities to automate and document the workflow, transforming it from a manual, high-touch process into a systematic and data-driven one. The execution protocol is designed to provide a complete audit trail, capturing every data point required for both internal analysis and external regulatory reporting. This systematization is critical for firms to manage the high volume of data generated and to ensure that their execution practices consistently meet the standards set by the directive.

The MiFID II Compliant RFQ Workflow

Executing a trade via RFQ under MiFID II involves a series of precise steps, each designed to ensure a competitive and auditable outcome. The process is embedded within the firm’s trading technology and is governed by its best execution policy.

1. Order Initiation and Pre-Trade Analysis ▴ An order, particularly one that is large-in-scale or in an illiquid instrument, is flagged for RFQ handling. The trader’s EMS provides pre-trade analytics, including historical liquidity and volatility data, to inform the execution strategy.
2. Counterparty Selection ▴ The trader, often guided by system-driven recommendations based on past performance, selects a list of liquidity providers to receive the RFQ. This selection process itself is a key part of the best execution policy and must be justifiable.
3. Quote Solicitation ▴ The RFQ is sent electronically and simultaneously to the selected counterparties. The request specifies the instrument, size, and side (buy/sell), and sets a time limit for responses.
4. Response Aggregation and Analysis ▴ The EMS aggregates the incoming quotes in real-time. The platform displays the prices and sizes from all responding dealers on a single screen, allowing for immediate comparison. The system also enriches this view with execution quality metrics.
5. Execution Decision ▴ The trader executes against the chosen quote. The decision is based not only on the best price but also on the other best execution factors, such as the likelihood of settlement and the size of the quote. The rationale for the decision, if not simply the best price, is often logged.
6. Post-Trade Processing and Reporting ▴ The execution details are automatically captured, time-stamped, and fed into the firm’s TCA systems. This data is then used to generate the necessary transaction reports for regulators and the RTS 28 reports for clients.

Data Capture for Best Execution Proof

The value of the electronic RFQ protocol is deeply tied to its data-capturing capabilities. To satisfy MiFID II’s requirements, the system must record a granular level of detail for every transaction. The following table provides an example of the critical data points captured during an RFQ process and their relevance to the best execution factors defined under the regulation.

The granular, time-stamped data captured during an electronic RFQ workflow provides the definitive evidence required to substantiate best execution decisions under MiFID II.

System Integration and Technological Architecture

The effective use of RFQs in the current market structure is dependent on sophisticated technological integration. The EMS or OMS acts as the central hub for the entire workflow. These platforms must have robust connectivity, typically via the FIX (Financial Information eXchange) protocol, to a wide range of liquidity providers, including SIs and MTFs. The FIX protocol has specific message types tailored for the quote negotiation process, allowing for the seamless and standardized exchange of information.

Furthermore, these systems must be integrated with the firm’s data warehousing and analytics infrastructure. The vast amount of quote data generated, even from trades not executed, is valuable for future trading decisions and for refining counterparty selection algorithms. This “quote graveyard” analysis helps firms understand which providers are most competitive in specific instruments and market conditions, allowing for a continuous improvement of the execution process and a more intelligent, data-driven approach to liquidity sourcing.

From Mandate to Mechanism

The integration of the RFQ protocol into the fabric of European equity trading is a clear demonstration of how markets adapt to regulatory drivers. What began as a set of compliance mandates under MiFID II has catalyzed the development of a more sophisticated and data-rich execution ecosystem. The regulation compelled a move towards greater structure and accountability, and the market responded by industrializing a protocol that delivers precisely those attributes. The evolution continues as technology refines the process further, incorporating machine learning for smarter counterparty selection and more advanced analytics for post-trade analysis.

A System of Continuous Refinement

The journey with MiFID II and its influence on market structure is one of ongoing adaptation. The data generated by these new, transparent workflows provides the raw material for the next wave of innovation in execution strategy. For institutional participants, the focus shifts from simply complying with the regulation to leveraging the tools and data it has brought forth. How can the rich data from RFQ workflows be used to build more predictive pre-trade models?
