2.3 Market Abuse & Insider Dealing
Key Takeaways
- Inside information is legally defined by four cumulative criteria: it must be of a precise nature, not publicly available, relate directly or indirectly to issuers or financial instruments, and be likely to have a significant effect on price if made public (meeting the reasonable investor test).
- Criminal insider dealing under the UK Criminal Justice Act 1993 covers three distinct offenses: dealing in price-affected securities using inside information, encouraging another person to deal, and disclosing inside information without lawful authority.
- Market manipulation under the Market Abuse Regulation encompasses fictitious devices, transaction-based manipulation (such as wash sales, spoofing, layering, and marking the close), and information-based dissemination of false or misleading statements.
- Regulated investment firms are under a mandatory legal obligation to report suspicious orders and transactions without delay to supervisory authorities via Suspicious Transaction and Order Reports (STORs).
- The Market Abuse Regulation provides specific Safe Harbours for legitimate buy-back programmes and stabilization measures, provided they adhere strictly to pricing, timing, volume, and public disclosure conditions.
2.3 Market Abuse & Insider Dealing
Fair, transparent, and orderly capital markets depend entirely upon investor trust. When market participants trade on secret information or manipulate prices through artificial volume or false rumours, honest investors are defrauded, capital allocation is distorted, and the cost of capital rises across the entire economy. To safeguard market integrity, financial jurisdictions maintain severe, dual-track legal frameworks combining criminal offenses with civil regulatory regimes.
The Dual Framework: Criminal vs. Civil Regimes
In the United Kingdom, market misconduct is prosecuted under two distinct legal architectures:
+-----------------------------------------------------------------------------------------+
| DUAL REGULATORY REGIMES FOR MARKET CONDUCT |
+--------------------------------------------+--------------------------------------------+
| CRIMINAL REGIME (CJA 1993 Part V) | CIVIL REGIME (Market Abuse Regulation - MAR|
+--------------------------------------------+--------------------------------------------+
| - Statute: Criminal Justice Act 1993 | - Statute: EU MAR (retained UK law via FSMA|
| - Standard of Proof: Beyond reasonable | - Standard of Proof: Balance of |
| doubt (criminal standard) | probabilities (civil standard) |
| - Penalties: Up to 10 years imprisonment | - Penalties: Unlimited financial fines, |
| and unlimited criminal fines | public censures, bans, restitution orders|
| - Scope: Individuals only; insider dealing | - Scope: Individuals & corporate firms; |
| only (manipulation under Fraud Act 2006) | insider dealing & market manipulation |
+--------------------------------------------+--------------------------------------------+
Because securing a criminal conviction requires proving mens rea (guilty intent) beyond reasonable doubt, the civil Market Abuse Regulation (MAR) provides regulators like the FCA with a flexible enforcement mechanism operating on the civil standard of proof—the balance of probabilities (i.e. more likely than not). This allows regulators to fine firms and individuals millions of pounds and ban them from financial services without requiring criminal prosecution.
Definition and Elements of Inside Information
Under Article 7 of the Market Abuse Regulation (MAR), Inside Information is defined as information possessing four cumulative statutory characteristics:
+-----------------------------------------------------------------------------------------+
| THE 4 ELEMENTS OF INSIDE INFORMATION |
+-----------------------------------------------------------------------------------------+
| 1. PRECISE NATURE | Specific events occurred or reasonably expected to occur |
| 2. NOT PUBLIC | Not released via an authorized Regulatory Info Service |
| 3. RELATES TO ISSUERS | Relates directly/indirectly to an issuer or instrument |
| 4. SIGNIFICANT PRICE EFFECT| Meets the 'Reasonable Investor Test' |
+-----------------------------+-----------------------------+-----------------------------+
- Precise Nature: Information is deemed precise if it indicates a set of circumstances that exists or may reasonably be expected to come into existence, or an event that has occurred or may reasonably be expected to occur, and is specific enough to enable a conclusion to be drawn as to the possible effect on prices. The information does not need to be mathematically exact: knowing that an acquisition bid will be made at a substantial premium is precise, even if the exact share price is not yet finalized.
- Not Generally Available / Not Public: The information has not been disseminated to the wider market through an authorized Primary Information Provider (PIP) or Regulatory Information Service (RIS) (such as the London Stock Exchange's RNS, PR Newswire, or Business Wire). Leaking information to a financial journalist, discussing it at a private dinner, or publishing it on an internet chat forum does not make the information public.
- Relates Directly or Indirectly to Issuers or Instruments: It may relate directly to an issuer (e.g. unexpected revenue collapse, loss of major patent, impending insolvency, resignation of CEO) or indirectly to the wider market (e.g. unannounced central bank interest rate decisions, commodity export embargoes, or changes in index weightings).
- Likely to Have a Significant Effect on Price (The Reasonable Investor Test): Information is price-sensitive if it is information that a reasonable investor would be likely to use as part of the basis of their investment decisions. If a reasonable investor would consider the information material when deciding whether to buy, hold, or sell, the test is satisfied.
Prohibited Insider Dealing Offenses
Under both the UK Criminal Justice Act 1993 (Part V) and the civil MAR framework, three primary offenses constitute insider dealing:
- Dealing: An individual who has inside information dealing in price-affected securities (buying or selling qualifying securities or related derivatives), or attempting to deal, whether as principal for their own account or as agent for another person.
- Encouraging or Recommending Another Person to Deal: Recommending, advising, or procuring another person to deal in securities to which inside information relates, knowing or having reasonable grounds to believe that dealing would take place. Crucially, the person giving the tip commits an offense even if they do not disclose the actual inside information itself.
- Unlawful Disclosure of Inside Information: Disclosing inside information to any other person outside the proper, lawful course of the exercise of an employment, profession, or duties. Tipping off a colleague, friend, or relative constitutes an immediate offense.
Legitimate Behaviors & Statutory Defenses
The law recognizes specific situations where an individual in possession of inside information may trade legitimately without committing an offense:
- Chinese Walls / Information Barriers: Where a firm maintains effective physical, operational, and electronic separation between departments (e.g. between the M&A advisory desk and the equity trading desk), individuals trading behind the barrier who do not possess the information are protected from liability.
- Legitimate Market Making: A registered market maker continuing to quote bid and ask prices and execute customer orders in the normal, bona fide course of market making.
- Discharge of Pre-Existing Obligations: Executing a trade in good faith to satisfy a legally binding obligation entered into before the party came into possession of the inside information.
- No Expectation of Dealing: Demonstrating that at the time of disclosing the information, there was no reasonable expectation that the recipient would deal on it.
Market Manipulation Typologies
Market manipulation involves artificial conduct designed to distort price discovery, fabricate false trading activity, or deceive investors regarding the true supply, demand, or price of financial instruments.
+-----------------------------------------------------------------------------------------+
| MARKET MANIPULATION TYPOLOGIES |
+--------------------------------------------+--------------------------------------------+
| TRANSACTION-BASED MANIPULATION | INFORMATION-BASED MANIPULATION |
| - Wash Sales (no change in ownership) | - Dissemination of False Statements / Rumor|
| - Spoofing & Layering (fake order depth) | - "Pump and Dump" Schemes |
| - Marking the Close (distorting fix/settle)| - "Trash and Cash" (bear raids) |
| - Churning (excessive commissions) | - Benchmark Manipulation (LIBOR, FX fix) |
+--------------------------------------------+--------------------------------------------+
1. Transaction-Based Manipulation
- Wash Sales: Executing simultaneous buy and sell orders in the same security through accounts controlled by the same beneficial owner, resulting in no real change in beneficial ownership or market risk, solely to fabricate the illusion of active market liquidity.
- Spoofing: Entering non-bona fide orders into the order book with the deliberate intention to cancel them immediately before execution. The spoof orders create a false impression of buy or sell pressure, moving the market so the manipulator can execute a real order on the opposite side at an artificial price.
- Layering: A sophisticated form of spoofing where a trader submits multiple fake orders at varying price increments across the order book, creating a deceptive visual "staircase" of volume to bait algorithmic market participants into moving prices.
- Marking the Close: Deliberately executing buy or sell orders at the immediate end of the trading day to artificially fix the closing price. Because closing prices determine mutual fund Net Asset Values (NAVs), daily collateral margin calls, executive stock options, and derivative cash settlements, marking the close causes widespread financial distortion.
- Quote Stuffing: Flooding electronic order books with tens of thousands of rapid quotes, modifications, and cancellations per second to congest network bandwidth, introduce execution latency for competitors, and profit from short-term algorithmic delay.
- Churning: A discretionary wealth manager executing an excessive number of trades in a client's portfolio that generate no economic benefit for the client, conducted solely to generate transaction commissions for the broker.
2. Information-Based Manipulation
- Dissemination of Misleading Information ("Pump and Dump"): Purchasing illiquid, micro-cap shares, circulating false or wildly exaggerated positive claims across financial message boards, social media channels, or investment newsletters to inflate the price, and then dumping the shares on unsuspecting retail buyers.
- "Trash and Cash": Short-selling a stock and subsequently spreading unfounded malicious rumours regarding accounting fraud, regulatory investigations, or impending bankruptcy to trigger panic selling.
- Benchmark Distortion: Transmitting fraudulent, manipulated, or collusive submissions to benchmark administrators to distort systemic interest rates (such as historical LIBOR and EURIBOR manipulation) or foreign exchange benchmark fixings (e.g. the 4:00 PM WM/Reuters FX fix).
Market Surveillance, Compliance Obligations & Safe Harbours
Investment firms, wealth managers, and trading venue operators must implement active surveillance frameworks to prevent and detect market misconduct.
1. Suspicious Transaction and Order Reports (STORs)
Under Article 16 of MAR, any person professionally arranging or executing transactions must establish automated trade surveillance systems and alert procedures. If the firm possesses a reasonable suspicion that an order or trade—including cancellations and amendments—could constitute insider dealing or market manipulation, it must submit a Suspicious Transaction and Order Report (STOR) to the competent national authority (the FCA in the UK) without delay.
Firms must not notify the client that a STOR has been filed, and filing a report in good faith protects the firm from civil or contractual liability.
2. Mandatory Insider Lists
Issuers, investment banks, and advisory firms must maintain detailed, timestamped Insider Lists under Article 18 of MAR. These lists record every individual working for the firm who has access to inside information:
- Deal-Specific / Event-Driven Lists: Maintained for specific projects (mergers, rights issues, profit warnings), documenting the exact date and minute the individual first accessed the information.
- Permanent Insider Lists: Senior executives, legal counsel, and compliance officers who have access to all inside information across the firm at all times.
Insider lists must record personal details—including legal names, national identification numbers, dates of birth, personal addresses, and personal telephone numbers—and must be kept for at least five years and submitted to regulators upon request.
3. Market Soundings Protocol
A Market Sounding occurs when an issuer or investment bank communicates inside information to prospective institutional investors prior to announcing a corporate transaction (e.g. an IPO, private placement, or bond issuance) to gauge investor interest and pricing appetite. MAR establishes a rigorous statutory protocol to protect market soundings from being classified as unlawful disclosure:
- The discloser must determine whether the interaction involves inside information and script the dialogue.
- The discloser must obtain the potential investor's consent to be "wall-crossed" and inform them that agreeing to receive the information makes them an insider, prohibiting them from trading in the relevant instruments.
- Keep comprehensive written or audio records of the interaction.
- When the project is publicly announced or abandoned, the discloser must formally issue a cleansing statement to the investor, releasing them from insider status.
4. Statutory Safe Harbours
The Market Abuse Regulation provides specific Safe Harbours that confer legal immunity from market abuse provisions for legitimate corporate activities that comply strictly with statutory conditions:
+-----------------------------------------------------------------------------------------+
| MAR STATUTORY SAFE HARBOURS |
+--------------------------------------------+--------------------------------------------+
| 1. SHARE BUY-BACK PROGRAMMES | 2. PRICE STABILISATION MEASURES |
+--------------------------------------------+--------------------------------------------+
| - Purpose: Capital reduction, meeting bond | - Purpose: Supporting share prices during |
| conversions, or employee share schemes | an IPO or secondary capital raise |
| - Trading Limit: Maximum 25% of the average| - Duration Limit: Maximum 30 calendar days |
| daily trading volume (ADTV) on the venue | from trading launch |
| - Price Cap: Cannot purchase above the | - Price Cap: Cannot stabilize above the |
| higher of last independent trade or bid | original public offering price |
| - Public Disclosure: Full terms announced | - Disclosure: Must notify market before & |
| prior to trading and reported weekly | confirm stabilized trades weekly |
