Concept

The distinction between lit and dark request-for-quote (RFQ) executions is fundamental to understanding modern market microstructure. A lit RFQ operates with pre-trade transparency, meaning the intention to trade is broadcast to a wider audience, contributing to public price discovery. Conversely, a dark RFQ is a bilateral or multilateral negotiation with no pre-trade transparency, designed to minimize market impact for large orders. The regulatory reporting requirements for these two execution methods differ significantly, reflecting their distinct roles in the market ecosystem.

Lit RFQ executions are subject to more comprehensive and immediate reporting obligations. Because these trades are intended to be transparent, regulators mandate that they are reported promptly to the public tape. This ensures that all market participants have access to the same pricing information, fostering a level playing field.

The reporting requirements for lit RFQs typically include the security, size, price, and time of the execution, as well as the venue of the trade. These details are essential for market surveillance and for providing a clear audit trail.

The core difference in reporting lies in the pre-trade transparency of lit RFQs versus the post-trade-only reporting of dark RFQs.

Dark RFQ executions, on the other hand, have delayed and less detailed reporting requirements. The primary purpose of a dark RFQ is to allow institutional investors to execute large trades without revealing their intentions to the broader market, which could lead to adverse price movements. To protect this anonymity, regulators permit delayed reporting of dark trades.

The specific reporting requirements vary by jurisdiction, but they generally involve reporting the trade to a regulatory facility within a specified timeframe, often at the end of the trading day. This post-trade transparency provides regulators with the necessary data for oversight without compromising the strategic objectives of the institutional investor.

Strategy

The choice between a lit and a dark RFQ is a strategic decision driven by the specific objectives of the trade. A lit RFQ is often employed when a trader wants to signal their interest to the market, potentially attracting more liquidity and achieving a better price. This strategy is particularly effective for smaller, more liquid orders where market impact is less of a concern.

By broadcasting the RFQ, a trader can create a competitive auction environment, forcing dealers to offer tighter spreads. The transparency of a lit RFQ also provides a clear benchmark for best execution, as the trade is executed in a public and observable manner.

Conversely, a dark RFQ is the preferred strategy for large, illiquid, or sensitive orders where minimizing market impact is paramount. Institutional investors often use dark RFQs to execute block trades without alerting the market to their intentions. This discretion is crucial for preventing information leakage, which can lead to front-running and other predatory trading practices.

The delayed reporting of dark RFQs allows these large trades to be absorbed by the market without causing significant price dislocations. The trade-off for this discretion is a potential reduction in price competition, as the RFQ is only sent to a select group of liquidity providers.

Strategic decisions on RFQ type hinge on the trade-off between the price discovery of lit venues and the impact mitigation of dark pools.

Comparing Lit and Dark RFQ Reporting Requirements

The following table provides a high-level comparison of the reporting requirements for lit and dark RFQ executions under a hypothetical regulatory framework:

Reporting Element	Lit RFQ	Dark RFQ
Pre-Trade Transparency	Yes	No
Post-Trade Transparency	Immediate	Delayed
Reporting Venue	Public Tape	Regulatory Facility
Reported Information	Full Details (Symbol, Size, Price, Time, Venue)	Limited Details (Symbol, Size, Price, Time)

Strategic Considerations for RFQ Selection

Order Size ▴ Larger orders are more suitable for dark RFQs to minimize market impact.
Liquidity of the Security ▴ More liquid securities can be traded using lit RFQs with less risk of adverse price movements.
Market Conditions ▴ In volatile markets, the discretion of a dark RFQ may be more valuable.
Urgency of the Trade ▴ If a trade needs to be executed quickly, a lit RFQ may provide faster access to liquidity.

Execution

The execution of lit and dark RFQs involves distinct operational workflows and regulatory reporting processes. For a lit RFQ, the process begins with the trader submitting the RFQ to a transparent trading venue, such as an exchange or a multilateral trading facility (MTF). The RFQ is then disseminated to all market participants, who can respond with their best quotes.

The trader selects the best quote, and the trade is executed and immediately reported to the public tape. This entire process is typically automated and occurs in a matter of milliseconds.

The execution of a dark RFQ is a more manual and discreet process. The trader sends the RFQ to a select group of liquidity providers, often through a dark pool or a single-dealer platform. The liquidity providers respond with their quotes, and the trader negotiates the terms of the trade.

Once the trade is executed, it is reported to a trade reporting facility (TRF) on a delayed basis. This delay can range from a few minutes to the end of the trading day, depending on the jurisdiction and the size of the trade.

The operational workflows for lit and dark RFQs are designed to support their respective goals of transparency and discretion.

Detailed Reporting Requirements under MiFID II

The Markets in Financial Instruments Directive II (MiFID II) is a key piece of European legislation that governs the reporting of financial transactions. The following table details the specific reporting requirements for lit and dark RFQ executions under MiFID II:

Reporting Field	Lit RFQ	Dark RFQ
Instrument Identifier	ISIN	ISIN
Price	Actual Price	Actual Price
Quantity	Actual Quantity	Actual Quantity
Venue	MIC of the Trading Venue	“XOFF” or “XXXX”
Publication Time	As close to real-time as possible	Delayed, based on the size of the trade
