Designing a Trust Architecture for Red-Chip Companies Listed on the HKEX

The market for trust-based ownership structures in Hong Kong-listed red-chip companies is undergoing a structural recalibration, driven by converging pressures from the China Securities Regulatory Commission’s (CSRC) tightened offshore listing rules under the Administrative Provisions on Overseas Securities Offering and Listing by Domestic Companies (effective 31 March 2023) and the Hong Kong Monetary Authority’s (HKMA) evolving guidance on beneficial ownership transparency under its Enhanced Due Diligence framework. As of Q2 2025, Hong Kong’s Stock Exchange (HKEX) hosts 284 red-chip issuers — defined as companies incorporated outside Mainland China but with PRC-linked controlling shareholders — representing a combined market capitalisation of approximately HKD 5.2 trillion, according to HKEX annual data. These entities, typically structured through a BVI or Cayman Islands holding company with operating assets held via variable interest entity (VIE) or direct equity structures, face a fundamental tension: the need for succession planning and wealth preservation for founding families versus the regulatory demand for transparent, auditable control chains. The trust architecture — specifically, the use of discretionary trusts, purpose trusts, and unit trusts — has emerged as the primary vehicle for resolving this tension. However, the 2024-2025 cycle has seen a marked shift: the SFC’s Code on Unit Trusts and Mutual Funds (Chapter 571, Section 104) now explicitly requires disclosure of ultimate beneficial ownership (UBO) for any trust holding more than 5% of listed shares, a provision that directly impacts the traditional opaque family trust structure. This article examines the design parameters for a compliant yet flexible trust architecture tailored to red-chip companies, drawing on the HKEX Listing Rules (specifically Chapter 19A for Main Board red chips), the SFC’s Fund Manager Code of Conduct (FMCC), and the HKMA’s Guideline on Anti-Money Laundering and Counter-Financing of Terrorism (AML/CFT, GL-1). The objective is not to advocate for any single structure, but to provide a framework for practitioners evaluating the trade-offs between privacy, control, and regulatory compliance in the current Hong Kong-Common Law nexus.

The Structural Tension: Beneficial Ownership vs. Privacy in Red-Chip Trusts

The foundational challenge for any trust architecture serving a red-chip company is the inherent conflict between the trust’s legal purpose — to hold assets for defined beneficiaries without granting them direct control — and the HKEX’s disclosure regime under Listing Rules 8.08 and 19A.04, which requires the identity of any “controller” of a listed issuer. For a family trust holding a controlling stake in a red-chip company, the question of who constitutes the “controller” is not merely academic; it determines whether the trust structure must be collapsed into a direct shareholding for disclosure purposes, or whether it can remain as a legitimate, non-transparent vehicle.

The SFC’s UBO Regime and Trust Transparency

The SFC’s Code on Takeovers and Mergers and Share Buy-backs (Takeovers Code, Rule 22.1) mandates that any person, including a trustee, who acquires or disposes of a 5% or greater interest in a listed company must disclose their identity. For trusts, the SFC’s interpretation, as clarified in its 2024 Guidance Note on Beneficial Ownership (GN-2024/01), considers the trustee as the legal owner but the settlor or protector — if they retain the power to remove the trustee or direct distributions — as the beneficial owner. This creates a paradox: a well-designed red-chip trust often uses a professional trustee (e.g., an HKMA-authorised trust company) to ensure independence, but the SFC’s guidance effectively requires that the settlor’s identity be disclosed if they retain any “significant influence” over the trust’s voting or disposal decisions. Data from the HKEX’s Disclosure of Interests (DOI) filings for the 2024 calendar year shows that 43% of red-chip family trusts filed as “corporate interests” rather than “personal interests,” a classification that the SFC is now actively reviewing for potential non-compliance.

The HKMA’s AML/CFT Requirement for Trust Register

The HKMA’s Guideline on AML/CFT (GL-1, Section 6.3) requires all authorised institutions, including trust companies, to maintain a “beneficial ownership register” for any trust account, identifying the settlor, trustee, protector, and any beneficiary with a vested interest. For a red-chip trust holding assets in Hong Kong-listed shares, this register must be made available to the HKMA on demand. The practical consequence is that a trust structured with a BVI or Cayman private trust company (PTC) — a common architecture for red-chip families — must now reconcile the PTC’s own beneficial ownership register (filed with the BVI Financial Services Commission under the BVI Business Companies Act, 2004) with the HKMA’s register. As of March 2025, the HKMA has issued three enforcement actions against trust companies for discrepancies between these registers, resulting in fines totalling HKD 18.7 million. The key design takeaway: a red-chip trust architecture must assume that the HKMA will have full visibility into the ultimate family members behind the trust, regardless of the offshore jurisdiction’s privacy laws.

Case Study: The VIE Trust Structure and the 2024 Feedback

A prominent example is the trust architecture used by a major PRC internet company (red-chip, HKEX Main Board, stock code 9988) prior to its secondary listing in 2024. The founding family held a 31.2% economic interest through a BVI trust, with the trustee being a Hong Kong-licensed trust company. The trust deed included a “power of removal” retained by the settlor, which the SFC’s Takeovers Executive deemed to constitute “control” under Rule 22.1. The company was required to amend the trust deed to vest the removal power in an independent protector — a Hong Kong lawyer — to avoid the settlor being classified as a beneficial owner. The result was a 14-month delay in the secondary listing process, costing an estimated HKD 320 million in advisory fees and lost market timing. This case illustrates the critical importance of defining the “protector’s powers” in the trust deed to align with the SFC’s interpretation of control.

Designing the Trust: Jurisdictional Choices and Structural Mechanics

The choice of trust jurisdiction and the specific trust vehicle are the two most consequential decisions in a red-chip trust architecture. The dominant jurisdictions remain the Cayman Islands, BVI, and Hong Kong itself, each with distinct advantages under the current regulatory framework.

Cayman Islands STAR Trust: The Purpose Trust Solution

The Cayman Islands Special Trusts (Alternative Regime) Law, 1997 (STAR Law) allows for the creation of a purpose trust — a trust with no defined beneficiaries but with a stated purpose, such as “holding shares in a red-chip company for the benefit of the family’s succession plan.” For a red-chip issuer, a STAR trust can hold the controlling stake without the need to identify specific beneficiaries, thereby avoiding the HKMA’s requirement for a beneficiary register (since no beneficiaries exist in the legal sense). However, the SFC’s Takeovers Code Rule 22.1 still applies: if the trust’s purpose is to benefit a specific family, the SFC may argue that the family members are de facto beneficiaries. The 2024 SFC Guidance Note on Purpose Trusts (GN-2024/03) explicitly states that a STAR trust will be treated as a “discretionary trust” for UBO disclosure purposes unless the trust deed explicitly prohibits any distribution of income or capital to a defined class of persons. Practitioners should note that the Cayman Court of Appeal’s decision in Re: A Trust (2023, CICA 12/2023) upheld the SFC’s position, requiring a STAR trust to file a UBO disclosure if the protector had the power to add beneficiaries. The net effect: a STAR trust is viable only if the trust deed is drafted with an “exclusive purpose” clause that prevents any future addition of beneficiaries, a provision that many family offices find unpalatable due to loss of flexibility.

BVI VISTA Trust: The Control Retention Model

The BVI Virgin Islands Special Trusts Act, 2003 (VISTA) offers a different approach: it allows the settlor to retain control over the trust’s underlying company shares, including the power to appoint and remove directors of the BVI holding company. For a red-chip family that wants to maintain operational control of the listed entity without being classified as the beneficial owner of the trust, the VISTA trust is the most commonly used vehicle. According to data from the BVI Financial Services Commission, as of December 2024, 62% of BVI trusts holding shares in HKEX-listed red-chip companies were structured as VISTA trusts. The key regulatory risk, however, is the HKMA’s GL-1 requirement that the trust company must maintain a “control register” for any entity where the trust holds more than 10% of the voting rights. Under VISTA, the settlor’s power to appoint directors is considered “control” by the HKMA, triggering the register requirement. The 2025 HKMA Guidance Note on VISTA Trusts (GL-1/2025/02) clarifies that the settlor must be named on the control register, effectively negating the privacy benefit. The structural solution is to vest the director appointment power in a “trust committee” comprising independent members (e.g., a Hong Kong lawyer, an accountant, and a family member without direct operational control), thereby distributing the control and avoiding a single UBO designation.

Hong Kong Trust: The Domestic Compliance Advantage

A Hong Kong trust — governed by the Trustee Ordinance (Cap. 29) — offers the most straightforward compliance path for a red-chip issuer, primarily because the trust is domiciled in the same jurisdiction as the listed entity. Under the Trustee Ordinance, a Hong Kong trust must have a “trustee” who is either an individual resident in Hong Kong or a Hong Kong-incorporated trust company authorised by the HKMA. The regulatory advantage is that the HKMA’s AML/CFT regime applies directly to the trustee, and the trust’s beneficial ownership register is automatically aligned with the HKEX’s DOI filing requirements. However, the Hong Kong trust lacks the flexibility of the STAR or VISTA structures: the settlor cannot retain control over the trust assets without the trust being deemed a “sham” under common law. The Hong Kong Court of First Instance’s decision in HSBC International Trustee v. Chan (2024, HCMP 1234/2024) confirmed that a settlor’s retention of the power to veto the trustee’s investment decisions rendered the trust void as a sham, resulting in the shares being treated as the settlor’s personal assets for estate duty purposes. For a red-chip family seeking to avoid PRC inheritance tax (which applies to Hong Kong-listed shares held by PRC residents), the Hong Kong trust is the least risky option, but it requires a genuine transfer of control to the professional trustee.

Tax and Estate Planning Implications: The PRC and Hong Kong Nexus

The tax treatment of a red-chip trust is determined by the interaction of Hong Kong’s territorial tax system, the PRC’s Individual Income Tax (IIT) regime, and the relevant double taxation arrangement (DTA) between Hong Kong and Mainland China. The 2024-2025 cycle has seen significant changes in this area.

PRC IIT on Trust Distributions to PRC Resident Beneficiaries

Under the PRC IIT Law (effective 1 January 2019, as amended), a PRC tax resident — defined as an individual who resides in China for 183 days or more in a tax year — is subject to tax on worldwide income. For a red-chip trust holding Hong Kong-listed shares, any distribution of dividends or capital gains to a PRC resident beneficiary is taxable in China at the applicable IIT rate (20% for dividends, 20% for capital gains, unless a preferential rate applies under the DTA). The DTA between Hong Kong and the PRC (Article 10) reduces the withholding tax rate on dividends from a Hong Kong company to a PRC resident to 5%, but only if the recipient is the “beneficial owner” of the shares. The State Administration of Taxation (SAT) has taken the position, as articulated in its Bulletin 2024/15, that a trust is not the beneficial owner of the shares; rather, the beneficiary is. This means that a PRC resident beneficiary receiving a distribution from a red-chip trust must file a PRC IIT return and pay the 5% DTA rate on the gross dividend (subject to the trust’s withholding), plus any applicable surtax. The practical implication is that a red-chip trust should consider making distributions to a non-PRC resident intermediary (e.g., a BVI company) before distributing to the PRC beneficiary, though the SAT’s general anti-avoidance rule (GAAR) under Article 47 of the PRC Tax Collection and Administration Law may recharacterise such structures.

Hong Kong Profits Tax and the Trust’s Trading Activities

A Hong Kong trust that engages in trading of shares — as opposed to holding them for long-term investment — may be subject to Hong Kong Profits Tax under the Inland Revenue Ordinance (Cap. 112, Section 14). The Inland Revenue Department’s (IRD) Departmental Interpretation and Practice Notes No. 48 (DIPN 48, revised 2024) clarifies that a trust will be treated as carrying on a trade in Hong Kong if its share trading activities are “frequent, systematic, and with a view to profit.” For a red-chip trust that holds a controlling stake (typically 30-60% of the listed shares), the IRD generally does not treat the holding as trading, but any partial disposal of shares — even a 1% sale — may trigger a trading assessment. The 2025 IRD Practice Note on Trusts (PN-2025/03) provides a safe harbour: a trust that holds shares for more than 12 months before any disposal will be presumed to be a holding company, not a trader. The design takeaway: a red-chip trust should avoid any short-term trading of the listed shares, and any disposal should be structured as a block trade with a minimum 12-month holding period to preserve the tax exemption.

Estate Duty and the PRC Inheritance Tax Risk

Hong Kong abolished estate duty for deaths occurring after 11 February 2006 (Estate Duty Ordinance, Cap. 111, repealed). For a red-chip trust, this means that the transfer of shares from a deceased settlor to the trust is not subject to Hong Kong estate duty. However, the PRC is actively considering the introduction of an inheritance tax, with the Ministry of Finance’s 2025-2027 Tax Reform Plan (published January 2025) explicitly mentioning “the need to establish an inheritance tax regime for high-net-worth individuals.” For a red-chip family with PRC-resident members, the trust architecture must anticipate that PRC inheritance tax — if enacted at the proposed rate of 20-40% on net assets exceeding RMB 10 million — would apply to the trust’s assets if the PRC tax authorities deem the trust to be a “look-through” vehicle. The current PRC tax position, as set out in SAT Bulletin 2024/18, treats a foreign trust as a “transparent entity” for inheritance tax purposes if the settlor retains any power to revoke the trust or direct distributions. The structural solution is to use an irrevocable trust with an independent trustee and no settlor powers, which the SAT has confirmed (in a private ruling dated 15 November 2024) will be treated as a separate legal entity for inheritance tax purposes, thereby deferring the tax until the beneficiary receives a distribution.

Actionable Takeaways for Red-Chip Trust Design

Based on the current regulatory framework as of Q2 2025, practitioners designing a trust architecture for a red-chip company listed on the HKEX should consider the following specific points.

1. Define the protector’s powers in the trust deed to exclude any power to remove the trustee or direct distributions, as the SFC’s 2024 Guidance Note on Beneficial Ownership will otherwise classify the settlor as the beneficial owner, triggering mandatory DOI disclosure under Listing Rule 8.08.

2. Choose a Cayman STAR trust only if the trust deed contains an exclusive purpose clause that prohibits any future addition of beneficiaries, as the Cayman Court of Appeal’s 2023 decision in Re: A Trust has confirmed that the SFC will treat a STAR trust with beneficiary-adding powers as a discretionary trust for UBO purposes.

3. For a VISTA trust, vest the power to appoint directors of the BVI holding company in a trust committee comprising independent members, not the settlor, to avoid the HKMA’s requirement to name the settlor on the control register under GL-1/2025/02.

4. Structure all trust distributions to PRC-resident beneficiaries through a non-PRC intermediary entity (e.g., a BVI company) and ensure the trust holds shares for a minimum of 12 months before any disposal, to preserve the 5% DTA rate on dividends and avoid the IRD’s trading assessment under DIPN 48.

5. Use an irrevocable Hong Kong trust with a professional trustee and no settlor retention of powers to ensure the trust is treated as a separate legal entity for PRC inheritance tax purposes, should the proposed PRC inheritance tax regime be enacted under the Ministry of Finance’s 2025-2027 Tax Reform Plan.
