## Concept

The Markets in Financial Instruments Directive II (MiFID II) fundamentally re-architects the relationship between a market maker and a trading venue, particularly under duress. It moves beyond ambiguous expectations and codifies obligations within a robust, multi-layered legal and operational framework. At its core, the regulation establishes a clear demarcation between two distinct states of market turmoil ▴ “[Stressed Market Conditions](https://prime.greeks.live/area/stressed-market-conditions/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” (SMC) and “[Exceptional Circumstances](https://prime.greeks.live/area/exceptional-circumstances/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” (EC). This is not a semantic distinction; it is a critical architectural feature that dictates a market maker’s precise duties.

Understanding this bifurcation is the foundational principle for navigating [liquidity provision](https://prime.greeks.live/area/liquidity-provision/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) in modern European markets. SMC represents a state of heightened, yet manageable, volatility where obligations are formally modified but absolutely remain in force. In contrast, EC represents a systemic failure or crisis event where the fundamental requirements to provide liquidity are temporarily suspended.

This entire system is built upon the non-negotiable requirement of a binding written “[Market Making Agreement](https://prime.greeks.live/area/market-making-agreement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” between the investment firm and the [trading venue](https://prime.greeks.live/area/trading-venue/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). This agreement is the central contractual instrument that translates the high-level principles of MiFID II into specific, enforceable parameters. It details the precise obligations for providing liquidity, the incentives offered for fulfilling those duties, and the clear, pre-defined adjustments that take effect during a declared SMC period.

An investment firm is generally identified as pursuing a [market making](https://prime.greeks.live/area/market-making/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) strategy, and thus required to enter into such an agreement, when it posts firm, simultaneous two-way quotes of a comparable size at competitive prices in at least one financial instrument on a single trading venue for at least 50% of the daily continuous trading hours, for half of the trading days over a one-month period. It is the firm’s responsibility to notify the venue of this activity, though venues are also tasked with proactively identifying firms that meet this threshold and compelling them to enter into an agreement.

> The regulatory framework under MiFID II formalizes a market maker’s duties during turmoil through contractually defined adjustments for stressed conditions and a full suspension for exceptional circumstances.

The concept of Stressed [Market Conditions](https://prime.greeks.live/area/market-conditions/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is instrument-specific and data-driven. A trading venue is required to establish clear parameters, typically based on significant short-term changes in price and volume, to identify when a specific financial instrument has entered an SMC state. A common trigger is the resumption of trading following a [volatility interruption](https://prime.greeks.live/area/volatility-interruption/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). When these pre-defined thresholds are breached for an instrument, the SMC protocol is activated automatically by the venue’s systems.

For the duration of the SMC period, which might be a set time like 60 minutes, the [market maker](https://prime.greeks.live/area/market-maker/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s obligations, as stipulated in their agreement, are recalibrated. This allows the firm to continue providing essential liquidity to the market, albeit under conditions that reflect the heightened risk environment. This architectural design seeks to prevent the complete withdrawal of liquidity [during periods](https://prime.greeks.live/question/how-should-a-counterparty-scoring-model-be-adjusted-during-periods-of-high-market-volatility/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) of sharp, but not catastrophic, market moves.

Exceptional Circumstances, on the other hand, are a system-wide release valve. These are events so severe that they compromise the integrity of the market or a firm’s ability to operate safely. The triggers are of a different magnitude than those for SMC. They include scenarios like extreme volatility across a majority of a venue’s listed products, widespread disorderly trading conditions, or external events such as acts of war or cyber sabotage.

A firm-specific technological failure or the inability to manage risk prudently can also qualify, provided the firm formally declares an emergency to the venue’s market supervision authority. Upon the declaration of EC by the venue, a market maker’s obligation to provide continuous liquidity under its agreement is fully suspended, releasing it from the duty to post quotes until the circumstances are resolved. This mechanism acknowledges that there are breaking points beyond which requiring a firm to make markets would introduce unacceptable systemic risk.

## Strategy

The strategic implications of [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)’s framework for stressed markets are profound for both [trading venues](https://prime.greeks.live/question/how-does-high-frequency-trading-interact-with-anonymous-trading-venues-and-institutional-order-flow/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) and investment firms. The regulation compels a move from reactive crisis management to a pre-planned, systematic response protocol. The core strategy for all participants is the management of risk and the preservation of market integrity through technologically embedded rules of engagement.

For trading venues, the strategy centers on creating a resilient and predictable market environment. For market-making firms, the strategy is a dual-pronged approach of continuous risk calibration and the optimization of performance against contractually defined incentives.

## Venue Strategy Maintaining Orderly Markets

A trading venue’s primary strategic objective [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 to prevent liquidity evaporation during periods of high volatility. The execution of this strategy rests on the implementation of robust, automated surveillance and flagging systems. The venue must define and calibrate the parameters that trigger a [Stressed Market Condition](https://prime.greeks.live/question/how-do-exchanges-define-stressed-market-conditions-for-market-makers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) for each class of instrument.

This is a critical strategic exercise involving quantitative analysis to set thresholds that are sensitive enough to activate when needed but not so sensitive that they are triggered by normal market noise. A common approach is to link the SMC trigger to volatility interruptions, automatically flagging a 60-minute SMC period upon the resumption of trading in a liquid instrument.

The venue’s strategy for Exceptional Circumstances is one of decisive, centralized control to prevent systemic collapse. The strategic playbook involves clear, pre-defined internal communication and decision-making protocols. For example, a venue might have a rule that if more than 50% of its tradable products experience a volatility interruption simultaneously, EC is automatically triggered for a set period.

This removes ambiguity and ensures a swift, market-wide response. The strategic communication to the market is equally vital, with flags and news messages indicating the start and end of these periods to ensure all participants are operating under the same set of rules.

## Market Maker Strategy Risk Calibration and Incentive Capture

For a market-making firm, the strategy is an intricate dance of risk management, algorithmic sophistication, and regulatory compliance. The foundation of this strategy is the Market [Making Agreement](https://prime.greeks.live/question/what-are-the-key-differences-between-a-prime-brokerage-agreement-and-an-isda-master-agreement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which the firm must negotiate with a clear understanding of its own risk appetite and operational capabilities. The firm’s trading algorithms must be architected to dynamically ingest and react to flags from the trading venue that signal a change in market state. When an SMC flag is received for a particular instrument, the firm’s strategy is to immediately adjust its [quoting parameters](https://prime.greeks.live/question/how-are-the-parameters-in-an-automated-quoting-system-optimized/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to the contractually permitted ‘stressed’ levels.

> A market maker’s strategic success depends on its system’s ability to fluidly transition between normal, stressed, and exceptional quoting parameters based on real-time venue flags.

This is a quantitative strategy. The firm’s systems must widen spreads and potentially reduce quote sizes to the new, permissible limits defined in the agreement. This recalibration allows the firm to continue participating in the market and collecting spreads, while also fulfilling its legal obligations and, crucially, qualifying for any financial incentives the venue offers.

Many venues, like Deutsche Börse’s [Xetra](https://prime.greeks.live/area/xetra/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), offer a 100% reimbursement of trading fees for trades executed during an SMC period, provided the market maker meets its [modified obligations](https://prime.greeks.live/question/can-a-standard-contract-be-modified-to-achieve-the-benefits-of-a-netting-agreement/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). Therefore, a key part of the firm’s strategy is to ensure its performance monitoring systems can accurately track its presence and quote parameters during SMC periods to guarantee it captures this significant economic benefit.

The following table illustrates the strategic shift in operational parameters across different market states as envisioned by the MiFID II framework.

### Table 1 ▴ Market State Condition Comparison

| Parameter | Normal Market Conditions | Stressed Market Conditions (SMC) | Exceptional Circumstances (EC) |
| --- | --- | --- | --- |
| Primary Trigger | Default state of operation. | Instrument-specific volatility interruption; significant short-term price/volume changes. | System-wide events ▴ >50% of products in volatility halt, disorderly trading, firm-declared emergency, cyber sabotage. |
| Market Maker Obligation | Continuous quoting per agreement (e.g. 50% presence, tight spreads). | Continuous quoting with modified parameters (e.g. 50% presence during SMC, wider spreads, potentially smaller sizes). | All quoting obligations are fully suspended. |
| Venue Response | Standard monitoring and surveillance. | Automatic system flag on the specific instrument; monitoring of compliance with modified obligations. | Manual or automatic declaration of EC; market-wide notification; suspension of trading if necessary. |
| Economic Incentive | Standard trading revenue; potential for baseline rebates. | Enhanced incentives, such as full trading fee reimbursement for compliant liquidity provision. | No specific incentives; focus is on risk mitigation and market stabilization. |

## What Is the Process for Declaring an Emergency?

A critical component of a market maker’s strategy is knowing when and how to use the “emergency brake” of declaring Exceptional Circumstances from its side. This is not a decision taken lightly. It is reserved for situations where the firm’s own systems are compromised, or its ability to manage risk is impaired to a degree that continuing to quote would be reckless. The process is formal and direct ▴ the firm must declare the emergency in writing (e.g. via a dedicated email address) to the venue’s market supervision department.

Upon receipt and acceptance, the venue exempts the member from its obligations for that day. This strategic option acts as a crucial safeguard, protecting both the firm and the broader market from the potential fallout of a localized, but critical, failure.

## Execution

Executing a MiFID II-compliant [market-making strategy](https://prime.greeks.live/area/market-making-strategy/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) during periods of stress is a matter of precise operational and technological implementation. It requires a seamless integration of legal agreements, algorithmic logic, and real-time data processing. The focus shifts from theoretical understanding to the granular, second-by-second actions of a firm’s trading systems and compliance personnel. Success in this environment is measured by a system’s ability to interpret [market state](https://prime.greeks.live/question/how-does-an-ems-maintain-state-consistency-across-multiple-trading-venues/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) changes correctly and adjust its behavior deterministically, ensuring compliance while managing risk and maximizing economic incentives.

## The Operational Playbook

For a compliance officer or head of trading at a market-making firm, a clear, actionable playbook is essential for navigating a Stressed [Market Condition](https://prime.greeks.live/question/what-constitutes-an-exceptional-market-condition-for-an-equity-systematic-internaliser/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) event. The following represents a procedural checklist for execution from the moment an SMC is declared by a trading venue.

- 
**Acknowledge The Signal** The firm’s trading system must be designed to receive and parse a specific electronic signal (e.g. a FIX tag or a proprietary API message) from the venue indicating that a specific instrument has entered an SMC state. The first operational step is the automated logging of this signal, creating an auditable record of the event’s start time.

- 
**Verify The Instrument And Parameters** The system must immediately cross-reference the affected instrument with its internal database, which contains the specific, pre-agreed SMC parameters from the Market Making Agreement. This database should hold the exact maximum spread, minimum [quote size](https://prime.greeks.live/area/quote-size/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), and presence percentage required during the SMC.

- 
**Trigger Algorithmic Parameter Adjustment** The core execution step is the automatic command sent to the quoting engine to switch from ‘Normal’ to ‘Stressed’ parameters. The algorithm must instantaneously widen its quoting spread to a level that is compliant with the new maximum. For example, if the normal maximum spread is 2.5% and the stressed maximum is 5%, the algorithm must adjust its pricing logic accordingly.

- 
**Engage Real-Time Monitoring** A dedicated monitoring dashboard should immediately begin tracking the firm’s performance against the SMC obligations. This dashboard must display, in real-time, the market maker’s ▴ 

<li>**Presence Percentage** Calculated as (Time spent with compliant two-sided quote on book) / (Elapsed time of SMC). The target is to remain above the required threshold (e.g. 50%).

- **Spread Compliance** A continuous check that the posted quotes are within the maximum permissible spread.

- **Size Compliance** A continuous check that the bid and ask volumes do not diverge by more than the stipulated percentage (e.g. 50%).

</li>
- 
**Manage The Liquidity Provision Flag** It is imperative that all quotes submitted during the SMC period are correctly flagged as part of the market-making strategy (e.g. via the “Liquidity Provision Flag” on an M-Account). This is a critical technical requirement for many venues to identify the activity as eligible for incentive schemes.

- 
**Reconcile Post-Event** Once the venue signals the end of the SMC period, the system logs the end time. The compliance team must then run a reconciliation report to verify that all obligations were met. This report will be the basis for claiming any fee rebates and will serve as proof of compliance in case of an inquiry from the venue or a regulator.

## Quantitative Modeling and Data Analysis

The execution of a market-making strategy under MiFID II is inherently quantitative. The following tables provide a granular, data-driven view of how the rules are applied in practice. The parameters are hypothetical but are based on the types of frameworks implemented by European trading venues.

### Table 2 ▴ Instrument-Specific Quoting Parameters Under Different Market Conditions

| Instrument Liquidity Class | Normal Max Spread | Normal Min Quote Size (EUR) | Stressed Max Spread | Stressed Min Quote Size (EUR) | Required Presence (Normal & Stressed) |
| --- | --- | --- | --- | --- | --- |
| LC 1 (High Liquid Equity) | 2.00% | 20,000 | 4.00% | 10,000 | 50% |
| LC 2 (Medium Liquid Equity) | 3.00% | 15,000 | 6.00% | 7,500 | 50% |
| LC 3 (Low Liquid Equity) | 4.00% | 10,000 | 8.00% | 5,000 | 50% |
| Liquid ETF | 2.00% | 25,000 | 4.00% | 12,500 | 50% |

The table above shows how obligations are precisely relaxed during a [Stressed Market](https://prime.greeks.live/area/stressed-market/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Condition. For a highly liquid stock (LC 1), the market maker can double its spread from 2% to 4% and halve its required quote size from €20,000 to €10,000. This allows the firm to price in the higher risk while still providing a baseline of liquidity.

> Effective execution hinges on a firm’s ability to translate the legal requirements of its Market Making Agreement into the precise, quantitative parameters that govern its algorithms.

## How Do Venues Calculate Incentives?

The financial incentive for compliance is a powerful execution driver. The following table models the calculation of a trading fee rebate for a market maker in a LC 1 equity during a 60-minute SMC period, assuming a [standard trading](https://prime.greeks.live/question/how-do-non-standard-clauses-alter-standard-pfe-calculations/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) fee of 0.20 bps (0.0020%).

### Table 3 ▴ SMC Incentive Calculation Example

| Metric | Value | Notes |
| --- | --- | --- |
| SMC Duration | 60 minutes | Declared by the venue from 14:30 to 15:30. |
| Presence Achieved | 54 minutes (90%) | Firm exceeded the 50% minimum presence requirement. |
| Total Passive Volume Executed | €5,000,000 | Total value of the market maker’s quotes that were hit during the SMC period. |
| Standard Trading Fees | €1,000 | Calculated as €5,000,000 0.000020. |
| SMC Compliance Status | Compliant | Presence, spread, and size obligations were met throughout the 54 minutes. |
| Fee Rebate (Incentive) | €1,000 (100%) | As the firm was compliant, it receives a full reimbursement of fees for passive execution. |

## System Integration and Technological Architecture

The execution framework described above is impossible without a sophisticated and resilient technological architecture. A market maker’s system must be designed for low-latency communication with the trading venue. This typically involves using the native [FIX protocol](https://prime.greeks.live/area/fix-protocol/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) or a more advanced binary protocol offered by the exchange. The system’s architecture must include a dedicated ‘venue adapter’ module responsible for normalizing data feeds from different exchanges.

This module must be capable of identifying and prioritizing SMC and EC flags over standard market data messages. The core trading application must be built around a state machine logic, where the ‘state’ of each instrument (Normal, Stressed, Exceptional) dictates which set of risk and quoting parameters are active. This requires not only algorithmic agility but also robust internal monitoring and alerting systems to notify human traders and compliance officers of any state changes or potential compliance breaches in real-time.

## Reflection

The MiFID II framework for market stress codifies a systemic truth ▴ liquidity is not an infinite resource, but a dynamic state governed by risk and incentives. The regulations force a structural maturity upon the market, demanding that all participants architect their operations around pre-defined protocols for volatility. The distinction between a ‘stressed’ market and an ‘exceptional’ one provides a grammar for discussing and managing turmoil. For the institutional principal, the value of this architecture extends beyond mere compliance.

It creates a more predictable, albeit more complex, ecosystem. Understanding the precise mechanics of this system ▴ the triggers, the modified obligations, the data flags ▴ is to understand the operational levers that now govern liquidity itself. The challenge is to ensure your own firm’s technological and strategic framework is not just compliant, but is built to capitalize on the structure these rules provide. How does your own operational playbook measure up against this new, systematic reality?

This is not a decision taken lightly. It is reserved for situations where the firm's own systems are compromised, or its ability to manage risk is impaired to a degree that continuing to quote would be reckless. The process is formal and direct: the firm must declare the emergency in writing (e.g. via a dedicated email address) to the venue's market supervision department. Upon receipt and acceptance, the venue exempts the member from its obligations for that day. This strategic option acts as a crucial safeguard, protecting both the firm and the broader market from the potential fallout of a localized, but critical, failure."
