HKEX Sets Strict Standards for Digital Asset Activities by Listed Companies

In July 2026, Hong Kong's stock exchange regulator published a detailed guidance letter that amounts to a clear message: you can do business with digital assets, but not if that's all you do. The letter, HKEX-GL122-26, clarifies how the exchange's existing listing rules apply to companies engaged in cryptocurrency and other digital asset activities—a question that had grown urgent as more firms explored this terrain and regulators worldwide grappled with how to supervise it.

The guidance builds on an earlier regulatory signal from November 2025, but this time HKEX went further, spelling out exactly what kinds of digital asset businesses it will and won't allow to list. The core distinction is sharp: a company whose principal business is simply buying and holding digital assets—what regulators call a digital asset treasury model—will not qualify for listing. HKEX views such firms as investment vehicles masquerading as operating companies, and the exchange has broad authority to reject them on suitability grounds. The rule applies to new applicants and existing listed companies alike. If a listed issuer drifts into this model, it risks trading suspension or delisting.

But HKEX explicitly rejected a blanket prohibition. The guidance acknowledges the "transformative potential" of digital assets and permits companies with genuine operating businesses to maintain material digital asset exposure. The catch is that there is no bright-line numerical test. Instead, regulators will examine the scale and purpose of the holdings, their relationship to the company's core operations, and whether they raise concerns about the company's substance as a going concern. A manufacturer that holds cryptocurrency as part of its treasury strategy looks different from a shell company that holds nothing else. The analysis is contextual, principle-based, and fact-specific.

For existing listed companies, the guidance identifies three specific risks. First, a company that holds substantial digital assets unrelated to its business may fail the "sufficiency of operations" test—the requirement that a listed issuer maintain a business with real substance and viable operations. Investment assets, even valuable ones, do not compensate for the absence of an actual operating business. Second, if digital assets held for investment purposes represent a very large portion of a company's total assets, the company may be classified as a cash company, which is unsuitable for continued listing under the rules. There is no fixed percentage threshold; HKEX applies a principle-based assessment considering the nature of the business, its ordinary cash needs, and the reasons for holding the digital assets. Third, if a listed company acquires a business consisting wholly or substantially of digital assets, the transaction may constitute a reverse takeover—a backdoor listing that circumvents the requirements imposed on new applicants. HKEX will examine whether the acquisition fundamentally changes the company's principal business and whether the acquired business has genuine substance or is merely a vehicle to maintain listing status.

When a listed company buys or sells digital assets, it must consider whether the transaction triggers disclosure and approval obligations. Most digital asset transactions are treated as notifiable or connected transactions under the listing rules, subject to certain exceptions. The main exception covers digital assets that function as money—central bank digital currencies and regulated stablecoins designed for payment and redeemable at par value in fiat currency. These are exempt from transaction reporting requirements because they serve an economic function analogous to cash. But companies cannot simply label an asset a stablecoin and claim the exemption; they must demonstrate that it meets the regulatory definition. Separate acquisitions of the same type of digital asset within a twelve-month period must be aggregated, so a company cannot evade disclosure by breaking a large purchase into smaller trades. Where shareholder approval is required, blanket approvals covering multiple types of digital assets over an extended period are unacceptable; shareholders must have enough information to make an informed decision.

The guidance places substantial weight on disclosure. When a company engages in digital asset activities with novel or unusual features, HKEX expects clear and balanced disclosure that helps investors understand the implications. Generic or boilerplate explanations of commercial rationale will not suffice. The company must describe the activities in detail, explain the board's reasoning, disclose management expertise, identify material risks and mitigation measures, describe custody and security arrangements, confirm legal compliance, and provide a timeline with key milestones. If the company is acquiring digital assets, it must explain whether those assets are integral to operations (and if so, how they will be deployed) or held for treasury or investment purposes (and if so, under what strategy and limits). If the company is tokenizing real-world assets, it must disclose who issued the tokens, what assets back them, what rights the tokens carry, and how they will be traded. Early-stage or preliminary proposals should not be announced without sufficient detail; if they are, the company must provide regular updates as the proposal develops.

One practical concern that emerged from recent market activity is the distribution of digital assets to shareholders. HKEX will scrutinize any in-specie distribution where shareholders are offered no reasonable cash alternative, particularly where some shareholders may be legally or practically unable to receive or sell the digital assets. The regulator's concern is straightforward: shareholders should not be forced to accept an unfamiliar or illiquid asset they cannot readily hold or sell. Finally, companies must monitor the fair value of digital assets monthly, disclose holdings that represent five percent or more of total assets in their financial reports, and maintain risk management and internal control systems proportionate to the scale and complexity of their digital asset activities.

The guidance arrives against a backdrop of regulatory caution. In August 2025, Hong Kong's Securities and Futures Commission and Monetary Authority issued a joint statement warning the public against irrational investment decisions based on corporate announcements about stablecoin applications or digital asset initiatives. The regulators noted that some companies had claimed recent engagement with authorities as evidence of approval or endorsement—a misrepresentation that contributed to abrupt share price movements. The Monetary Authority emphasized that approval thresholds for stablecoin issuer licenses are high and only a handful will be granted initially. For listed companies, the implication is clear: an announcement of intent to apply for a stablecoin license or engage in digital asset activities must be accurate, complete, and not misleading, and must include the detailed disclosure HKEX now requires. The regulator is watching for hype, speculation, and false claims of regulatory blessing.
