When Market Makers Pull Quotes

In the orderly world of equity market microstructure, one event triggers fear above all others: the disappearance of market-maker quotes. A security that moments ago could be bought and sold at posted bid-ask prices suddenly shows no quotes at all. Or quotes reappear at prices so distant from recent trades that they're economically irrelevant to current trading. When market makers pull their quotes—withdraw from the market and stop providing continuous liquidity—everything breaks down. Orders can't execute. Prices become uncertain. Traders are stranded. Understanding when and why market makers pull quotes, and what it means for market functioning, reveals the limits of the market-maker business model and the fragility of market liquidity.

Quick definition: Pulling quotes occurs when a market maker completely withdraws their bid and ask prices from the market, ceasing to provide continuous liquidity in a security. This can be temporary (seconds to minutes) or extended (hours), and ranges from tactical repositioning to fundamental exit decisions.

Key Takeaways​

  • Market makers pull quotes when risks exceed what they can economically compensate for
  • Technology failures, connectivity issues, and data feed problems force quote withdrawal
  • Extreme volatility, inventory imbalances, and information asymmetry create conditions where pulling quotes becomes rational
  • Regulatory obligations constrain market makers' ability to pull quotes, with penalties for unjustified withdrawal
  • Quote pulls create trading halts and price discovery problems
  • Circuit breakers and halts are designed to distinguish between market-maker withdrawal and fundamental market stress
  • Modern market makers employ redundancy and backup systems to minimize involuntary quote pulls

Why Market Makers Pull Quotes​

There are fundamentally five categories of reasons why market makers pull quotes:

Technology failures: A market maker's quoting system crashes, their data feeds go down, or their connection to the exchange fails. Without real-time market data and the ability to transmit quotes, they cannot trade safely. They pull quotes until systems are restored.

Risk management: When inventory risk, adverse selection risk, or overall market risk becomes unmanageable, a market maker may choose to pull quotes rather than accept catastrophic losses. This is a rational business decision—withdraw and preserve capital rather than face potential bankruptcy.

Regulatory compliance: A market maker who discovers they're out of compliance with quoting obligations (for example, their spread has widened beyond the regulatory maximum, or they don't have connectivity to execute trades they're quoting) must pull quotes until they're back in compliance.

Liquidity crisis: During extreme market stress where fundamental fair value is unknown and bid-ask spreads become inverted (bid higher than ask), market makers pull quotes because orderly quoting is impossible.

Negative news or events: Upon learning material information that makes fair value assessment difficult (a halt in the underlying company's stock, regulatory action, unexpected corporate events), a market maker may pull quotes until they can assess the situation.

Each category involves different time scales, regulatory consequences, and market impacts.

Technology-Driven Quote Pulls​

Technology-driven quote pulls are involuntary—the market maker wants to quote but can't. These occur when:

Data feed failures: Market makers depend on real-time feeds of prices, trades, volumes, and news. If the feed from an exchange or data provider breaks, the market maker is flying blind. They can't see what prices other market makers are quoting, they don't know the most recent trades, and they don't know the current order book state. Quoting under these conditions risks massive losses. They pull quotes until the feed is restored.

Connectivity failures: Market makers need reliable, low-latency connections to exchanges to submit and update quotes. If a primary connection fails, they may have a backup, but if both fail, they can't transmit quotes. They pull quotes until connectivity is restored.

System crashes: The market maker's internal systems—order management system, risk management system, quoting engine—may crash. Without these systems, they can't manage their positions or monitor their compliance. They pull quotes until systems are up and running.

Regulatory reporting failures: If a market maker can't reliably report their quotes and trades to regulators, they may be required to cease quoting until they're back in compliance.

These involuntary pulls are brief (typically seconds to minutes) and are designed to be minimized through redundancy and backup systems. Exchanges and regulators expect market makers to maintain backup systems so that single failures don't cause quote withdrawal.

However, during the 2010 Flash Crash and again during the 2020 COVID crisis, widespread technology problems affected multiple venues simultaneously, causing temporary but severe disruptions in market-maker quoting and creating trading halts.

Risk Management Decisions to Pull Quotes​

More interesting economically are voluntary quote pulls—where a market maker decides that the risk is too high and chooses to exit the market.

Extreme inventory imbalance: A market maker holds far more inventory than they're comfortable with. Rather than continue quoting at wider and wider spreads (which becomes unprofitable), they pull quotes and liquidate their existing inventory. Once they're back near their target inventory, they resume quoting.

Example: A market maker in a stock faces extreme selling pressure. They accumulate a long position of 500,000 shares—far more than they intended. Spreads have widened to 25 cents. They're losing money on every quote. They pull quotes, liquidate their excess inventory (accepting losses if necessary), and resume quoting once inventory is manageable.

Extreme adverse selection risk: Information flow suggests informed traders are active. The market maker faces the prospect of trading with traders who know something they don't. Rather than quote and be picked off by informed traders, they pull quotes and wait for the information asymmetry to resolve.

Example: A company announces unexpected news that could be good or bad depending on interpretation. Fair value is unknown. The market maker doesn't have conviction about the direction. Rather than quote wide spreads and risk being on the wrong side of a directional move, they pull quotes until the information becomes clear.

Fair value uncertainty: Fundamental understanding of fair value breaks down. This can occur when:

  • A company announces unexpected earnings or material events
  • Regulatory decisions are imminent
  • Broader market shocks occur that make re-pricing of the security necessary
  • Data feeds show inconsistent information

When fair value is genuinely uncertain, market makers pull quotes because any price they quote is likely to be wrong.

Capital constraints: A market maker's regulatory capital is exhausted or nearly exhausted. They cannot hold additional inventory without violating capital requirements. They pull quotes to prevent further inventory accumulation until capital ratios recover.

Volatility extremes: When realized volatility reaches extreme levels (100%+ annualized, or more), the probability of catastrophic loss on holding inventory becomes unacceptable. Market makers pull quotes.

Example: During the COVID crash of March 2020, spreads in some securities widened to 50-100 cents or more, and many market makers pulled quotes entirely. The volatility was so extreme that the risk-reward was unacceptable.

Regulatory Constraints on Quote Pulling​

Market makers operating under regulatory quoting obligations cannot freely pull quotes whenever they want. They must maintain quotes at specified spreads and sizes. If they pull quotes unjustifiably, they face:

Violations and enforcement: The SEC, FINRA, and exchanges monitor for quote pulling. Unjustified pulls trigger investigations. Market makers must document why they pulled—system failure, regulatory compliance issues, or extraordinary circumstances.

Fines and sanctions: FINRA and exchanges have fined market makers for unjustified quote pulls. In one 2015 case, FINRA fined a major market maker $3.2 million for, among other violations, failing to maintain continuous quotations.

Reputation damage: Repeated unjustified quote pulls can label a market maker as unreliable, harming their business relationships and client confidence.

Loss of market maker status: In extreme cases, repeated or egregious quote pulls can result in loss of market maker designation and removal from the exchange's approved market maker list.

These constraints mean market makers don't pull quotes lightly. They typically must have compelling reasons and must be able to justify their decisions to regulators.

However, regulations also recognize extraordinary circumstances. During extreme volatility, market makers are allowed to pull quotes temporarily. Exchanges invoke circuit breakers to halt trading, which eliminates the obligation to quote during the halt. The regulatory philosophy is to balance the need to require continuous liquidity provision with the reality that some conditions are too extreme for orderly quoting.

The Types of Quote Pulls​

Partial pulls: A market maker pulls quotes in some securities but not others, or pulls quotes on one side of the market (buy side but not sell side) but not the other. This is tactical—they manage their exposure by reducing inventory in certain securities while maintaining liquidity elsewhere.

Time-limited pulls: A market maker stops quoting but commits to resuming after a specific time (e.g., "I'm pulling quotes for 5 minutes to rebalance inventory, then I'll resume"). This is less disruptive than indefinite pulls.

Width pulls: A market maker doesn't pull the bid and ask entirely, but moves them to extreme widths that are technically still compliant with regulations but are so wide as to be economically irrelevant. The market maker is "quoting" but in a way that effectively withdraws from active trading.

Selective pulls: A market maker remains available to trade for certain clients or order types (e.g., large institutional orders) while pulling public quotes. This allows them to continue operating while avoiding small retail orders.

Complete withdrawal: A market maker simply stops quoting and stops trading, exiting the market entirely. This is the most extreme form.

What Happens When Market Makers Pull Quotes​

When a significant market maker pulls quotes, several things happen:

Order book deteriorates: The limit order book—the collection of buy and sell orders from traders waiting at specified prices—becomes the primary source of liquidity. But the order book is often thinner than market-maker quotes, creating wider effective spreads.

Price discovery fails: Without market makers continuously updating their quotes based on new information, prices may not adjust quickly to reflect new information. Price discovery becomes sluggish.

Trading halts: If market makers representing a significant portion of liquidity pull quotes, exchanges may invoke trading halts (circuit breakers) to prevent disorderly trading.

Forced trading outcomes: Traders who need to execute may be forced to accept far worse prices than they would normally. Instead of buying at the ask, they may have to buy from limit orders posted far above the previous ask, incurring large slippage.

Spillover effects: If one major security's market makers pull quotes, it can create uncertainty that spreads to related securities, causing market-wide stress.

The Flash Crash: A Case Study​

The May 6, 2010 Flash Crash provides a clear example of what happens when market makers pull quotes. On that day:

  1. Order flow shift: A large seller offloaded a substantial position, creating heavy selling pressure.

  2. Market maker inventory pressure: Market makers accumulated large long positions as they tried to provide liquidity to the seller.

  3. Algorithm interactions: A large trade algorithm, executing gradually, met the resistance of market makers with heavy inventory. The algorithm continued selling aggressively.

  4. Quote withdrawal: As inventory accumulated and losses mounted, multiple market makers pulled quotes or widened spreads dramatically.

  5. Liquidity vanishes: With key market makers out of the market, liquidity evaporated. The next wave of sellers had no counterparties.

  6. Cascade: Prices gapped down sharply in a matter of seconds, with some securities declining 30-40% and instantly recovering.

  7. Trading halts: Exchanges triggered circuit breakers, halting trading and giving the market time to stabilize.

The Flash Crash illustrated how dependent modern markets are on market maker participation. When they pull quotes—whether forced by technological failures or rational response to excessive risk—markets can break down in seconds.

Post-Flash Crash, regulators implemented:

  • Single-stock circuit breakers: Trading halts when individual stocks move too much too fast
  • Clearly erroneous trade rules: The ability to cancel trades that occurred at clearly incorrect prices
  • Market-wide circuit breakers: Broader halts when overall market stress is extreme

Technology Improvements to Reduce Unwanted Quote Pulls​

Recognizing that quote pulls harm market functioning, market makers and exchanges have invested heavily in technology to prevent involuntary pulls:

Redundant systems: Market makers maintain multiple primary quoting systems and backup systems that can take over if a primary fails. Some large firms have three or more geographically distributed backup systems.

Diversified data feeds: Rather than relying on a single data feed for market data, market makers subscribe to multiple feeds and cross-check them. If one feed fails, others remain.

Redundant connectivity: Market makers maintain multiple network connections to exchanges—primary connections, backup connections, and sometimes multiple independent providers.

System resilience: Modern quoting systems are designed to continue operating during partial failures. Rather than crash, they degrade gracefully, potentially narrowing spreads or reducing sizes but continuing to quote.

Testing and drills: Market makers regularly test their backup systems through scheduled drills. They also conduct stress tests to identify potential failure points.

Exchange infrastructure: Exchanges invest in redundant trading infrastructure. Multiple matching engines, multiple order books, multiple data centers. The goal is to ensure that trading can continue even if parts of the infrastructure fail.

These investments have made involuntary quote pulls far less common than they were in earlier decades. However, during the COVID crash, widespread stress still caused quote pulls across many securities, showing that extreme stress can overwhelm even highly redundant systems.

Market Maker Obligations vs. Systemic Risk​

There's a fundamental tension in market-making regulation: the goal of ensuring continuous market liquidity vs. the goal of preventing systemic failures when market makers are forced to hold unmanageable positions.

If quoting obligations are too strict—if they force market makers to quote even when risk is extreme—market makers will suffer massive losses and potentially fail. This threatens the financial system.

If quoting obligations are too loose—if market makers can easily pull quotes—liquidity disappears when most needed, harming investors.

Regulators attempt to navigate this tension through:

Graduated obligations: Tighter quoting obligations during normal periods, relaxed during stress. During extreme volatility, exchanges allow wider spreads and smaller sizes.

Circuit breakers: These automatically halt trading when stress becomes extreme, temporarily eliminating quoting obligations and giving market makers time to rebalance.

Regulatory capital requirements: Counter-cyclical capital requirements that are more lenient during stress, allowing market makers to hold inventory despite stress.

Systemically important institution designations: Some large market makers are designated as systemically important and subject to enhanced requirements to maintain liquidity during stress.

Emergency lending: Central banks (Federal Reserve, ECB, etc.) provide emergency liquidity to market makers during crises to prevent forced liquidation.

Real-World Examples of Quote Pulling​

The August 5, 2011 Volatility Spike: A sharp decline in equity prices triggered concerns about sovereign debt. Multiple market makers pulled quotes or widened them dramatically as inventory accumulated and risk spiked. Trading was disorderly for several hours.

March 2020 COVID Crash: On March 12, 2020, equity volatility spiked dramatically. Multiple market makers pulled quotes in numerous securities. Corporate bond spreads widened from 50-100 basis points to 200-500 basis points. Trading in many securities halted or was extremely disorderly. The Federal Reserve intervened aggressively in bond markets to restore liquidity.

August 2015 China Devaluation: The surprise devaluation of the Chinese currency triggered concerns about global growth. Volatility spiked across multiple assets. Market makers pulled quotes in foreign currency markets, creating trading halts and disorderly pricing.

Leveraged ETF Decay Spiral (2018-2020): Certain inverse (short) leveraged ETFs, including XIV (short volatility ETF), experienced flash crashes where prices diverged sharply from fair value. In February 2018, XIV dropped from $17 to $0.06 in a single day. Market makers pulled quotes as they faced massive inventory imbalances, unable to determine fair value.

Common Mistakes in Understanding Quote Pulls​

Mistake 1: Assuming quote pulls are evidence of market failure. Quote pulls are a rational response to extreme conditions. They protect market makers (and by extension, the financial system) from catastrophic losses.

Mistake 2: Believing quotes are never pulled. Quotes are pulled regularly, though it's usually brief and may not be visible to most traders. Regular, brief pulls for system maintenance or inventory rebalancing are normal.

Mistake 3: Thinking pulling quotes is illegal. It's not illegal—it's regulated. Market makers can pull quotes under certain circumstances, subject to regulatory approval and limits.

Mistake 4: Confusing trading halts with market maker quote pulls. Trading halts are exchange-initiated circuit breakers that stop trading for all participants. Quote pulls are market maker decisions. Halts can be triggered by quote pulls, but they're distinct.

Mistake 5: Assuming markets always need continuous market making. In extreme conditions, intermittent trading (with halts) may be preferable to continuous trading with very wide spreads and distorted prices.

FAQ​

Q: Can a market maker pull quotes whenever they want? A: No. Regulatory quoting obligations constrain when they can pull. They must have documented reasons and may face fines or sanctions for unjustified pulls.

Q: What happens to my order when a market maker pulls quotes? A: If you've submitted an order and market makers pull their quotes, your order may be matched against other traders' limit orders in the order book, or it may remain unexecuted until the market maker resumes quoting.

Q: Are quote pulls rare? A: Brief, tactical pulls are common and largely unnoticed. Extended pulls are rare and typically only occur during significant stress.

Q: How long does a quote pull typically last? A: Technology-driven pulls are usually seconds to a few minutes. Risk-management pulls may last longer, from minutes to hours. Extreme volatility pulls may last for the remainder of the trading day.

Q: If a market maker pulls quotes, can they be sued? A: Not typically, unless they violated regulatory rules. Quoting obligations are regulatory matters, not contractual matters between the market maker and individual traders.

Q: Do high-frequency traders pull quotes more often than traditional market makers? A: HFTs pull quotes more frequently because they operate on shorter time scales. But their pulls are typically milliseconds long and are not disruptive.

Q: What happens to the broader market if a major market maker pulls quotes? A: If a single market maker pulls briefly, others typically step in and fill the void. If multiple major market makers pull simultaneously, liquidity can evaporate and trading halts may be triggered.

Q: Can I prevent being impacted by quote pulls? A: You can use limit orders (patient orders) rather than market orders (urgent orders). Limit orders don't demand execution at market-maker quotes and aren't impacted by quote pulls.

  • Circuit Breakers: Automatic trading halts that prevent cascading volatility and give market makers time to rebalance
  • Trading Halts: Exchange-initiated pauses in trading, distinct from market-maker quote pulls
  • Clearly Erroneous Trade Rule: The ability to cancel trades that occurred at prices far from fair value, often triggered by quote pulling events
  • Systemic Risk: Risk that failures of key market participants (like major market makers) threaten the financial system
  • Order Book: The collection of buy and sell limit orders that provide liquidity when market makers pull quotes
  • Price Discovery: The process by which prices adjust to reflect new information, disrupted when market makers pull quotes

Regulatory frameworks on market maker obligations and trading halts:

Summary​

Market makers pull quotes when risks become unmanageable or when they're unable to operate due to technology failures or compliance issues. While regulators restrict unjustified quote pulling to maintain continuous market liquidity, they also recognize extraordinary circumstances where pulling quotes is rational and necessary.

Quote pulls create disruptions to market functioning: wider spreads, slower price discovery, and trading halts. These disruptions have motivated significant investments in redundant systems and regulatory mechanisms like circuit breakers designed to prevent cascading quote pulls.

Understanding when and why market makers pull quotes reveals the economic limits of market making. Market makers are not obligated to commit suicide—to accept catastrophic losses to maintain quoting. They can and do withdraw when conditions become too extreme. The fact that markets function nearly continuously despite this is a testament to the careful design of regulatory obligations, circuit breakers, and the willingness of market makers to internalize significant risk.

The relationship between market maker quote pulls and market stability remains an active area of regulatory concern and technological innovation.
