How to Use a Trust Structure to Participate in Hong Kong Government Infrastructure Bonds?

The Hong Kong government’s 2025-26 Budget, delivered by Financial Secretary Paul Chan on 26 February 2025, projected a consolidated fiscal deficit of HKD 87.2 billion for the 2025-26 financial year, with operating expenditure reaching HKD 623.0 billion. To finance this gap and the planned HKD 120.0 billion in infrastructure spending over the next five years, the government has signalled a significant ramp-up in bond issuance under the Government Bond Programme (GBP). The total issuance ceiling for the GBP is proposed to be raised to HKD 600.0 billion from HKD 300.0 billion, with the Silver Bond and Green Bond programmes integrated into this framework. For high-net-worth families and institutional investors, direct participation in these sovereign issuances is straightforward but offers limited structural flexibility. The emerging strategic question is how to use a Hong Kong trust structure to participate in these bonds—not merely as a passive holder, but as a vehicle for yield enhancement, asset protection, and cross-generational wealth transfer within a regulated framework. This article examines the specific mechanics, regulatory parameters, and tax implications of embedding Hong Kong government infrastructure bonds within a trust structure.

The Mechanics of Bond Participation via a Hong Kong Trust

A Hong Kong trust, governed by the Trustee Ordinance (Cap. 29) and common law principles, can be a direct subscriber or secondary market purchaser of Hong Kong government bonds. The trustee, whether a licensed trust company under the Trust or Company Service Providers (TCSP) regime (AMLO, Cap. 615) or a private individual, holds the legal title to the bonds, while the beneficiaries hold the beneficial interest. This separation is the core structural advantage.

Direct Subscription and Custody Arrangements

For institutional trustees, participation in a new government bond issuance—such as a Green Bond or Infrastructure Bond tranche—is executed through a primary dealer or a licensed broker. The trustee opens a segregated custody account with a Hong Kong Monetary Authority (HKMA)-recognised custodian bank. The HKMA’s “Guide to the Government Bond Programme” (latest revision, 2024) specifies that eligible participants include banks, brokers, and recognised investment funds. A trust structure qualifies as an eligible investor if the trustee is a licensed institution or the trust is a recognised fund.

The practical step involves the trustee executing a subscription agreement with a placing agent. The trust deed must explicitly authorise the trustee to invest in sovereign debt instruments. Standard trust deeds for Hong Kong family trusts often include a “permitted investments” schedule that must be amended to include “bonds, notes, or other debt securities issued or guaranteed by the Government of the Hong Kong Special Administrative Region or the HKMA.” Without this specific clause, the trustee may be in breach of fiduciary duty under Section 3 of the Trustee Ordinance, which requires investment to be in accordance with the trust instrument.

Secondary Market Trading and Liquidity Management

Hong Kong government bonds trade on the HKMA’s Central Moneymarkets Unit (CMU) platform. A trust can buy and sell bonds in the secondary market. The trustee must manage the liquidity profile of the trust. For example, a fixed-rate infrastructure bond with a 10-year tenor may have a coupon of 3.75% (based on the HKMA’s 10-year reference note yield of 3.82% as of 10 March 2025). The trustee needs to assess whether the bond’s duration aligns with the trust’s distribution obligations to beneficiaries.

A critical regulatory point: the trustee must comply with the SFC’s Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (Cap. 571). If the trustee is a licensed corporation, it must ensure that the bond investment is suitable for the trust’s risk profile. For a discretionary trust, the trustee has broader authority, but the investment decision must still be documented in an investment policy statement (IPS) approved by the trust’s protector or the settlor, if still alive.

Tax and Regulatory Advantages of the Trust Structure

The tax treatment of Hong Kong government bonds held within a trust structure is distinct from direct individual holding. Hong Kong’s territorial tax system applies, but specific exemptions exist for government bonds.

Profits Tax Exemption and Stamp Duty Implications

Under the Inland Revenue Ordinance (Cap. 112), interest income derived from Hong Kong government bonds is exempt from profits tax. Section 26A(1) of the IRO specifically exempts “interest payable on any bond issued under the Government Bond Programme.” This exemption applies regardless of the holder’s status. For a trust, this means the interest income flows through to the trust’s income account without any Hong Kong profits tax liability.

Stamp duty is a more nuanced consideration. Transfers of Hong Kong government bonds are exempt from stamp duty under the Stamp Duty Ordinance (Cap. 117), Schedule 1, Head 1(1), provided the transfer is effected through the CMU. A trust structure that involves a change of beneficial ownership—for example, a distribution of bonds to a beneficiary—may trigger stamp duty if the legal title is transferred. The trustee should structure distributions as an in-specie transfer of the beneficial interest only, leaving the legal title with the trustee, to avoid the 0.1% ad valorem stamp duty on the transfer of Hong Kong stock. Bonds are not “stock” under the Ordinance, but the legal advice must confirm the specific instrument.

Estate Planning and Succession Benefits

The primary non-tax advantage is the avoidance of probate. A Hong Kong government bond held directly by an individual forms part of their estate and requires a grant of probate from the High Court upon death. This process takes an average of 6 to 12 months in Hong Kong, during which the bond’s coupon payments may be frozen. In a trust structure, the bond is an asset of the trust, not the individual’s estate. The successor trustee or the protector can continue managing the bond without court intervention.

This is particularly relevant for cross-border families. A Hong Kong trust holding government bonds provides a Hong Kong-domiciled asset that is outside the probate jurisdiction of the settlor’s home country. For a PRC resident settlor, the bond held in a Hong Kong trust is not subject to the PRC Inheritance Tax (which, while not yet enacted, is under active discussion in the National People’s Congress). The trust structure effectively ring-fences the asset from the settlor’s personal estate.

Structuring for Yield Enhancement and Leverage

The conservative nature of government bond yields—typically 3.5% to 4.0% for 10-year HKGBs—can be enhanced within a trust structure through leverage and derivative overlays, provided the trustee acts within the bounds of prudence.

Leveraged Bond Mandates and the SFC’s Suitability Rules

A trust can borrow against the bond portfolio to invest in additional bonds or other assets. The HKMA’s “Supervisory Policy Manual” (SPM) module IR-1 on “Interest Rate Risk” does not directly regulate trusts, but a licensed trustee must assess the leverage ratio. A common structure is a 70:30 loan-to-value (LTV) ratio on the bond portfolio. For a HKD 10 million bond holding, the trust could borrow HKD 7 million at a margin rate of HIBOR + 100 bps (approximately 5.0% as of March 2025). The net yield on the leveraged position would be: (HKD 10 million * 3.75%) – (HKD 7 million * 5.0%) = HKD 375,000 – HKD 350,000 = HKD 25,000, or 0.25% on the total portfolio. This is a negative carry trade unless the bond yield exceeds the borrowing cost.

The SFC’s “Code of Conduct for Persons Licensed by or Registered with the SFC” (paragraph 5.1) requires that any leveraged investment must be “appropriate” for the client. For a trust, the “client” is the trust itself, but the trustee must consider the beneficiaries’ interests. A protector or investment committee should approve the leverage mandate in writing.

Derivative Overlays for Duration Management

Interest rate swaps and bond futures can be used to manage duration risk. A trustee expecting rising interest rates can enter into a pay-fixed, receive-floating interest rate swap to hedge the bond’s fixed coupon. The HKMA’s “Code of Practice for Unit Trusts and Mutual Funds” (Chapter 7) does not apply to private trusts, but the trustee must still ensure that derivative transactions are covered by a master agreement under ISDA documentation. The trust’s counterparty credit risk must be monitored, and the trustee should only deal with HKMA-authorised institutions.

The practical limit is the trust deed’s prohibition on speculative trading. Most Hong Kong family trust deeds restrict the trustee from engaging in “speculation” or “trading as a principal.” A derivative overlay for hedging is permissible; a speculative short position on bond futures is not. The distinction must be documented in the IPS.

Regulatory Compliance and Reporting Obligations

Operating a trust that holds Hong Kong government bonds requires adherence to multiple regulatory frameworks, from the TCSP regime to the AML/CFT requirements.

TCSP Licensing and Ongoing Compliance

Any person or entity that provides trust services in Hong Kong must be licensed under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (AMLO, Cap. 615). The trustee must register with the Companies Registry as a TCSP. The TCSP must conduct customer due diligence (CDD) on the settlor, the beneficiaries, and any protector. For a trust holding HKD 10 million or more in government bonds, the TCSP must file a suspicious transaction report (STR) if the source of funds is unclear.

The HKMA’s “Guideline on Anti-Money Laundering and Counter-Financing of Terrorism” (revised 2023) applies to authorised institutions that act as custodians for the trust’s bond holdings. The trustee must provide the custodian bank with a certified copy of the trust deed and a register of beneficial ownership. Failure to do so may result in the custodian refusing to open the account, citing Section 5 of the AMLO.

Annual Reporting and Tax Filing

The trust must prepare annual financial statements, which include the bond portfolio’s market value and accrued interest. Even though the interest income is tax-exempt, the trust must file a Profits Tax Return (IR56B series) if it has any other income. The trustee must also report to the Inland Revenue Department (IRD) any distributions to beneficiaries. For a Hong Kong resident beneficiary, distributions of bond interest are not subject to tax in the trust structure, but the beneficiary must declare the income in their personal tax return if they are resident in a jurisdiction that taxes worldwide income, such as the United States or the United Kingdom.

For a trust with a PRC resident settlor, the IRD may request information under the Common Reporting Standard (CRS). The trust’s “controlling persons” (the settlor, protector, and beneficiaries) must be identified and reported to the IRD, which then exchanges this information with the PRC tax authorities. This is a critical consideration for families seeking privacy.

Case Study: A BVI Trust Investing in HKGBs via a Hong Kong Trustee

A practical example illustrates the structure. A family with a BVI trust (governed by BVI Trustee Ordinance, Cap. 303) wishes to invest HKD 50 million in Hong Kong government infrastructure bonds. The BVI trustee is a licensed trust company in the BVI but not licensed as a TCSP in Hong Kong. The BVI trustee cannot directly hold the bonds in a Hong Kong custodian account without a Hong Kong TCSP license.

The solution is a Hong Kong sub-trust. The BVI trust appoints a Hong Kong-licensed trust company (e.g., a major bank’s trust division) as the trustee of a Hong Kong sub-trust. The BVI trust is the sole beneficiary of the Hong Kong sub-trust. The Hong Kong trustee subscribes for HKD 50 million in bonds through a primary dealer. The bonds are held in a CMU account in the name of the Hong Kong trustee.

The tax implications: the BVI trust is not subject to Hong Kong profits tax on the bond interest. The BVI trust’s own tax position depends on BVI law, which imposes no income tax. The family beneficiaries, who are PRC residents, receive distributions from the BVI trust. Under PRC tax law, these distributions are considered foreign-source income and are subject to PRC Individual Income Tax at a flat 20% rate, unless the beneficiary can prove the income has been taxed elsewhere. This structure requires careful PRC tax planning.

Actionable Takeaways

1. Amend the trust deed explicitly to include Hong Kong government bonds as a permitted investment, referencing the Government Bond Programme, to avoid a breach of fiduciary duty under the Trustee Ordinance.

2. Use a Hong Kong-licensed TCSP as trustee for direct bond holdings to ensure compliance with AMLO and to avoid the need for a BVI or Cayman trustee to obtain a separate Hong Kong license.

3. Leverage the profits tax exemption under Section 26A(1) of the IRO by ensuring all bond interest is routed through the trust’s income account and not commingled with taxable income.

4. Document the hedging strategy in an investment policy statement if using derivatives or leverage, distinguishing between hedging and speculation to remain within the trust deed’s constraints.

5. File CRS reports accurately identifying all controlling persons, as the IRD has increased scrutiny on trusts with PRC settlors following the 2024 CRS compliance review.
