Insider trading risk is not just a legal issue for individuals. It is a control issue for firms.
When material non-public information is mishandled, the consequences can extend well beyond one trade. Firms can face regulatory scrutiny, internal investigations, books-and-records failures, reputational damage, and questions about whether their controls were ever strong enough to begin with. Regulators continue to treat insider dealing, unlawful disclosure, and poor recordkeeping as serious threats to market integrity. The FCA states that insider dealing and unlawful disclosure are prohibited under the UK Market Abuse Regulation, while the SEC continues to stress that firms must preserve business communications and maintain appropriate records.
For compliance teams, the goal is straightforward: reduce the likelihood of employee misuse of inside information, establish defensible controls over access to MNPI, and make it easier to detect issues before they become enforcement matters.
Insider trading generally refers to trading securities while aware of material non-public information, or tipping that information to someone else who then trades on it.
The precise legal framework varies by jurisdiction, but the core idea remains the same. A person should not gain an unfair market advantage by using confidential information that has not been made available to the market. The SEC’s Rule 10b5-1 framework addresses trading “on the basis of” material non-public information, and the FCA states that UK MAR prohibits persons in possession of inside information from using it to deal, attempt to deal, or recommend that another person transact on that basis.
This means insider trading risk is not limited to direct buying or selling. It can also involve recommending trades, amending or canceling orders while in possession of inside information, or passing such information to others.
Material non-public information, or MNPI, is confidential information that a reasonable investor would consider important when deciding to buy, sell, or hold a security.
Examples may include:
Information is material if it could influence an investment decision or affect a security's market price. It is non-public if it has not been made generally available to the market.
Tip - Do not rely on the job title as a proxy for MNPI access. Sensitive information often reaches support staff, project teams, advisers, and external parties long before it reaches the market.
Insider trading undermines fair price formation and damages confidence in markets.
If some participants can trade using information that others do not have, the market no longer operates on equal terms. That affects trust, and trust is central to liquid, functioning markets. The FCA describes insider dealing and market manipulation as forms of market abuse, and in a 2025 speech, it said organized crime groups linked to insider trading represent one of the most serious threats to market abuse.
For firms, the risk is not only external. Weak handling of inside information can create internal culture problems, raise surveillance red flags, and expose the organization to scrutiny around governance, supervision, and books and records.
A blackout period is a defined period during which certain employees, executives, directors, or other insiders are restricted from trading in company securities.
These periods are typically used when the firm knows that certain people may have access to inside information. A common example is the period before earnings results are announced. Outside that restricted period, firms may allow trading during a defined trading window, often subject to additional controls such as pre-clearance.
Blackout periods are useful, but they are not enough on their own. A person can still hold MNPI outside a scheduled blackout period, which is why firms also need insider lists, wall-crossing controls, and escalation processes.
Enforcement actions in APAC show that insider trading risk is real and can lead to significant consequences for individuals and firms.
In Singapore, the ASe announced in June 2022 that former Broadway Industrial Group CFO Tan Chee Keong was sentenced to prison for insider trading after sharing non-public, price-sensitive information with a friend and personally benefiting.
In Australia, ASIC announced in June 2022 that former Sigma Healthcare general manager Michael Story was sentenced to 14 months’ imprisonment for insider trading, released on recognizance and good behavior conditions, and fined A$30,000 after selling shares while in possession of inside information about a key contract renewal.
These cases matter because they show two common patterns. One involves tipping off others with inside information. The other involves direct insider trading on confidential information. Firms need controls that address both.
Tip - Use real enforcement examples in training. Employees understand the risk more clearly when they see how ordinary business events like contracts, earnings, or deal activity can turn into insider trading cases.
A firm does not need to be accused of insider trading itself to face serious consequences.
Control failures around personal trading, communications capture, insider list management, or books and records can all increase regulatory risk. The SEC has repeatedly emphasized the importance of preserving business communications, and in past enforcement sweeps it imposed major penalties on firms for recordkeeping failures tied to business communications conducted on unapproved channels. SEC Chair Gary Gensler said in 2022 that such recordkeeping has been vital to preserving market integrity since the 1930s.
For compliance teams, that is an important point. Insider trading prevention depends partly on conduct controls and partly on the ability to reconstruct who knew what, when they knew it, how they communicated, and what trading followed.
A stronger prevention framework usually combines policy, surveillance, escalation, and culture.
Every listed or regulated firm that faces insider trading risk should have a clear securities trading policy. The policy should explain who is covered, what counts as inside information, when trading is restricted, when pre-clearance is required, and what escalation steps apply if an employee believes they may hold MNPI.
The policy should also address tipping, not just direct trading.
Personal trade monitoring can help firms spot unusual activity, especially where a proposed or completed trade appears inconsistent with a person’s trading history, access level, or current role.
Monitoring alone will not prove misconduct, but it can surface patterns worth reviewing. This is especially important when personal trading sits close to corporate events, restricted securities, or insider list activity.
Blackout periods only work if relevant employees understand when they apply and why. Firms should clearly communicate restrictions, identify affected populations, and avoid relying on informal reminders.
Insider lists are one of the most practical controls in this area. A good insider list helps the firm track who has access to MNPI, why they were given access, when they were added, and when they were removed. The FCA’s best practice note says firms should be able to identify, control, and document the handling of inside information effectively.
Tip - Treat insider lists as live operational records, not static evidence files. Their value is highest when they are updated in real time as access changes.
Pre-clearance allows the firm to review an employee’s proposed trade before it happens. This helps determine whether the employee may be restricted due to a blackout, insider list status, a watch list issue, or another conflict.
Done properly, pre-clearance creates a useful control point and a strong audit trail.
Employees should know how to raise concerns if they see suspicious trading, unusual information sharing, or pressure to act on confidential information. A reporting culture can surface issues that surveillance tools miss.
Policies matter, but culture determines whether people follow them. Employees are less likely to rationalize risky behavior when senior leaders communicate clearly that misuse of confidential information is unacceptable, even if no one believes they will get caught.
Tip - The strongest insider trading controls are usually the ones employees see as normal business discipline, not special compliance obstacles.
Many firms operate across multiple jurisdictions, which means insider trading risk cannot be managed solely through a single local policy.
In the U.S., insider trading liability is shaped by federal securities law and SEC enforcement, including Rule 10b5-1, which governs trading while aware of MNPI. In the UK, the UK MAR prohibits insider dealing and unlawful disclosure. In Singapore and Australia, MAS and ASIC enforcement show similar concern with the misuse of confidential information and tipping.
For global firms, the practical answer is usually to build one high-standard control framework that can be adapted locally where needed, rather than creating disconnected local processes.
A strong article on this topic should also show how the process operates in practice.
Determine when information may be material and non-public.
Limit access on a need-to-know basis and record who receives it.
Track who has access, why, and for how long.
Use blackout periods, restricted lists, and event-based controls where needed.
Pre-clear employee trades and compare them against relevant restrictions.
Review completed trades, communications, and suspicious patterns, then investigate when needed.
Insider trading risk is rarely controlled by a single policy.
Firms reduce risk when they combine a clear securities trading policy, live insider list management, disciplined blackout and pre-clearance processes, trading surveillance, and a culture that treats confidential information seriously. Recent enforcement actions in Singapore and Australia, along with continued focus by the SEC and FCA, show that regulators still view this as a live conduct and market integrity issue.
The firms that stay out of the headlines are usually not the ones with the longest policy documents. They are the ones who can show their controls work in practice.
Insider trading generally refers to trading securities while aware of material non-public information, or tipping that information to someone else who then trades on it. In the U.S., Rule 10b5-1 addresses trading “on the basis of” MNPI, and in the UK, UK MAR prohibits persons in possession of inside information from dealing, attempting to deal, or recommending a transaction on that basis.
MNPI is confidential information that a reasonable investor would likely consider important when deciding whether to buy, sell, or hold a security. It is non-public because it has not been broadly disclosed to the market. Examples can include pending mergers, earnings results, financing activity, or major commercial developments.
Insider trading harms market integrity by giving some participants an unfair advantage and reducing confidence that markets operate on equal terms. The FCA treats insider dealing and unlawful disclosure as market abuse, and has said these threats undermine trust in markets.
Blackout periods are defined periods during which certain directors, executives, employees, or other insiders are restricted from trading in company securities because they may have access to inside information. They are commonly used before earnings announcements, but firms often also need event-driven restrictions outside scheduled blackout periods.
A firm can face regulatory scrutiny, investigations, penalties, and reputational harm even if the issue is not a proven insider trading case. Weak books-and-records controls, poor communications capture, incomplete insider lists, or weak personal trading oversight can all increase enforcement risk.
Firms should have a securities trading policy, insider list procedures, blackout period controls, a pre-clearance process for personal trades, escalation paths for MNPI handling, and monitoring of personal trading and relevant communications. These controls help firms show who had access to inside information and how trading decisions were restricted or reviewed.
Insider lists help firms track who has access to MNPI, why they were given access, when they were added, and when they were removed. This makes it easier to control access, support investigations, and respond to regulatory questions about who knew what and when.
Yes. In Singapore, MAS announced that former Broadway Industrial Group CFO Tan Chee Keong was convicted and sentenced to 3 months and 2 weeks’ imprisonment for insider trading and acquiring benefits from criminal conduct. In Australia, ASIC announced that former Sigma Healthcare general manager Michael Story was sentenced to 14 months’ imprisonment, released on recognizance and good behaviour conditions, and fined A$30,000 for insider trading.
