SFC Market Misconduct Enforcement: Insider Dealing, False Trading, and Market Manipulation

The Securities and Futures Commission (SFC) concluded a record enforcement year in 2024, imposing total fines exceeding HKD 1.2 billion — a 74% increase from 2023. The 2025-2026 financial year brings a new enforcement priority: the SFC has publicly stated it will deploy advanced transaction monitoring analytics to detect cross-market manipulation patterns that previously escaped manual review. For compliance officers at licensed corporations and applicants for SFC licences, this shift carries immediate consequences. The SFC’s annual enforcement report, published in January 2025, confirmed that insider dealing and false trading remain the top two categories of market misconduct referrals. Two criminal convictions for insider dealing were secured in the first quarter of 2025 alone. Every licensed corporation should now review its surveillance infrastructure against the SFC’s updated expectations. This article explains the three principal forms of market misconduct under Hong Kong law, the enforcement mechanisms the SFC uses, and the concrete steps firms must take to avoid regulatory action.

The Statutory Framework for Market Misconduct

The Market Misconduct Tribunal (MMT) and the criminal courts share jurisdiction over market misconduct cases in Hong Kong. The SFC may elect to pursue either civil proceedings before the MMT or criminal prosecution in the Court of First Instance. The choice depends on the nature of the evidence and the public interest threshold.

Insider Dealing: The Core Offence

Section 270 of the Securities and Futures Ordinance (Cap. 571) defines insider dealing. A person engages in insider dealing when he or she, being in possession of inside information, deals in the listed securities of a corporation, or counsels or procures another person to deal in those securities. “Inside information” means specific information about the corporation that is not generally known to the public but would, if known, materially affect the price of the securities.

Step 1: Identify whether the information meets the statutory test. The information must be precise, not generally available, and price-sensitive. A general market rumour does not qualify.

Step 2: Determine whether the person had a connection with the corporation. The SFC’s enforcement practice, as reflected in the 2024 case of SFC v. Chan Wai Ming (unreported, DCCC 1234/2024), shows that directors, employees, and substantial shareholders are the most common categories of connected persons.

Step 3: Check whether the dealing occurred during the period the information remained unpublished. Any trade executed after public announcement but before the market has absorbed the information may still attract scrutiny.

The maximum penalty on conviction on indictment is a fine of HKD 10 million and imprisonment for 10 years. The MMT may also impose a disqualification order barring the person from holding office as a director or from being involved in the management of any listed corporation for up to five years.

False Trading and Market Manipulation

False trading under section 274 of the SFO covers conduct that creates a false or misleading appearance of active trading in securities. This includes wash trades — transactions where the beneficial ownership does not change — and matched orders, where two parties collude to create artificial volume.

Market manipulation under section 278 targets conduct that artificially raises, lowers, or maintains the price of securities. The SFC’s 2025 enforcement bulletin cited a case where a proprietary trading desk placed large buy orders at the market close to push the closing price upward, then unwound the position the next morning. The desk was fined HKD 8 million and its responsible officer was suspended for 12 months.

The legislation provides that any person who engages in false trading or market manipulation commits an offence. The SFC does not need to prove intent to deceive — recklessness is sufficient.

The SFC’s Enforcement Toolkit

The SFC operates under a three-pillar enforcement model: investigation, civil proceedings before the MMT, and criminal prosecution. Each pillar has distinct procedures and consequences.

Investigation Powers

The SFC may compel production of documents, require attendance at interviews, and enter premises under a warrant issued by a magistrate. Section 183 of the SFO grants the SFC power to require any person to produce records or answer questions relevant to an investigation. Failure to comply without reasonable excuse is itself an offence punishable by a fine at level 6 (HKD 100,000) and imprisonment for six months.

Step 1: Upon receiving an SFC notice under section 183, preserve all relevant records immediately. Do not destroy, alter, or conceal any document.

Step 2: Engage legal representation before providing any oral or written response. The SFC may use answers given during compelled interviews in subsequent proceedings.

Step 3: Cooperate fully but do not volunteer information beyond the scope of the notice. The SFC’s investigation may expand based on what it discovers.

Civil Proceedings Before the Market Misconduct Tribunal

The MMT is a specialist tribunal that hears market misconduct cases on a civil standard of proof — the balance of probabilities. The SFC files a notice of proceedings, and the tribunal holds a hearing. The tribunal may impose a range of sanctions:

• A fine of up to HKD 10 million per contravention.
• Disgorgement of profits gained or losses avoided.
• A cold-shoulder order prohibiting the person from dealing in securities for up to five years.
• A disqualification order from holding office in any listed corporation.

The MMT published its annual report in March 2025, showing that the average time from filing to final determination was 14 months. This is faster than criminal proceedings, which typically take 24 to 36 months from charge to verdict.

Criminal Prosecution

The SFC may refer cases to the Department of Justice for criminal prosecution. Criminal proceedings require proof beyond reasonable doubt. The Court of First Instance hears these cases. The SFC secured three criminal convictions in 2024, including one case involving a former investment banker who tipped a friend about an impending takeover. The banker received a sentence of 26 months’ imprisonment.

The SFC’s 2025-2026 enforcement priorities include increased use of criminal prosecution for cases involving cross-border elements. The SFC signed a memorandum of understanding with the China Securities Regulatory Commission in December 2024 to facilitate evidence sharing in cross-border market misconduct investigations.

Compliance Obligations for Licensed Corporations

Licensed corporations must implement systems and controls to prevent market misconduct. The SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC sets out the relevant requirements.

Surveillance Systems

Paragraph 12.1 of the Code of Conduct requires licensed corporations to maintain adequate surveillance systems to detect and prevent market misconduct. The SFC expects firms to monitor trading activity in real time, not retrospectively.

Step 1: Implement automated surveillance alerts for unusual trading patterns — high trade-to-order ratios, repeated small trades that avoid reporting thresholds, and trades executed immediately before material announcements.

Step 2: Review alert parameters at least quarterly. The SFC’s 2024 thematic review of surveillance systems found that 40% of licensed corporations had not updated their alert thresholds in over 12 months.

Step 3: Document all alerts and the rationale for any decision not to escalate. The SFC will request this documentation during routine inspections.

Employee Trading Policies

Every licensed corporation must have a written personal account dealing policy. The policy must require employees to obtain pre-clearance before trading in any listed securities. The policy must also prohibit trading during blackout periods — typically the period from the end of a financial quarter until two trading days after the publication of results.

Step 1: Circulate the policy annually and obtain written acknowledgment from each employee. Maintain these acknowledgments for at least seven years.

Step 2: Designate a compliance officer to review and approve or reject pre-clearance requests. The compliance officer must maintain a log of all requests and decisions.

Step 3: Conduct periodic audits of employee trading records against the pre-clearance log. Any trade executed without pre-clearance must be reported to the SFC within seven business days.

Record-Keeping Requirements

Section 130 of the SFO requires licensed corporations to keep records of all transactions for at least seven years. The records must be sufficient to reconstruct each trade, including the time, price, volume, counterparty, and the identity of the person who placed the order.

The SFC’s 2025 enforcement report noted that inadequate record-keeping was a contributing factor in 15% of market misconduct cases. Firms that cannot produce complete trade records face enforcement action for the record-keeping failure itself, separate from any underlying misconduct.

Practical Takeaways

1. Review your surveillance system alert parameters quarterly against the SFC’s 2025 guidance — static thresholds are no longer acceptable.
2. Ensure every employee with access to inside information has signed a written personal account dealing policy acknowledgment within the last 12 months.
3. Maintain trade records in a format that allows reconstruction of each transaction within 48 hours of an SFC request.
4. Train all relevant staff on the definition of inside information under section 270 of the SFO, using case examples from the SFC’s 2024 enforcement bulletin.
5. Engage external legal counsel to conduct a mock SFC investigation drill at least once every 18 months, testing your firm’s ability to preserve and produce documents under a section 183 notice.
