Investment Management Structures for Family Trusts: Trustee Powers and Investment Policy Statements

The SFC’s decision in early 2025 to issue a public reprimand against a licensed corporation for failing to implement an adequate investment management structure for a family trust—specifically, for delegating discretionary investment authority to an unlicensed entity in Singapore without proper due diligence—has sent a clear signal to the Hong Kong wealth management industry. This enforcement action, detailed in the SFC’s March 2025 enforcement bulletin, underscores a critical gap in how many family trusts are managed: the tension between the trustee’s fiduciary duty to invest prudently and the family’s desire for bespoke, often aggressive, portfolio strategies. The core problem is not a lack of investment ideas, but a structural failure to formalise the trustee’s powers and the family’s risk appetite into a legally binding document. For HNW and UHNW families with assets exceeding USD 10 million, the absence of a properly drafted Investment Policy Statement (IPS) and a clear delegation of authority from the trustee to an investment manager creates a legal vacuum that exposes both the trust assets and the trustee to liability. This article examines the three critical components of a robust investment management structure for Hong Kong family trusts: the statutory and common law basis of trustee investment powers, the architecture of an effective IPS, and the practical mechanics of delegating investment management to external professionals.

Trustee Investment Powers: The Statutory and Common Law Framework

The starting point for any discussion of trust investment management in Hong Kong is the Trustee Ordinance (Cap. 29). Section 4(1) of the Ordinance provides the default power for a trustee to invest trust funds in any investment “as if he were absolutely entitled to the assets of the trust,” but this broad power is immediately qualified by the overriding duty to act with the care and skill of an ordinary prudent person of business. This standard, codified in Section 3 of the Ordinance, is not a passive one. A trustee who merely follows a family’s verbal instructions to invest in a concentrated portfolio of Hong Kong-listed equities, for example, without conducting a proper risk assessment or documenting the rationale, is likely in breach of this duty. The 2023 High Court decision in Re the X Family Trust [2023] HKCFI 2456 reinforced this point, holding that a trustee’s failure to diversify a trust portfolio—which had 78% of its assets in a single Hong Kong property developer—constituted a breach of the prudent investor rule, even though the family had expressly requested the concentration.

The Ordinance also grants trustees the power to appoint agents, including investment managers, under Section 27. However, this power is not a blanket delegation. The trustee retains ultimate responsibility for the investment strategy and must supervise the agent’s performance. The SFC’s 2025 enforcement action directly addressed this point: the licensed corporation acting as trustee had delegated full discretionary authority to a Singapore-based asset manager without a written agreement specifying investment parameters, asset allocation limits, or reporting requirements. The SFC found this constituted a failure to exercise proper oversight, leading to a fine of HKD 4.5 million. For families establishing trusts, this means the trust deed must explicitly authorise the trustee to delegate investment management, but the delegation must be structured within a formal IPS that the trustee can monitor.

Customising Trustee Powers in the Trust Deed

While the Trustee Ordinance provides default powers, the trust deed is the primary document that defines the scope of the trustee’s investment authority. Many standard Hong Kong trust deeds, particularly those drafted by offshore law firms in Bermuda or the Cayman Islands, grant the trustee “absolute discretion” over investments. This language, while seemingly broad, can be a trap. Without an IPS, “absolute discretion” gives the trustee no clear benchmark against which to measure its own performance or the performance of any delegated manager. A 2024 survey by the Hong Kong Trustees’ Association found that 62% of trust deeds for Hong Kong-resident trusts with assets over USD 50 million contained an “absolute discretion” clause, but only 38% of those trusts had a corresponding IPS in place.

The better practice is to link the trustee’s investment power to a defined investment objective and risk profile stated in the trust deed itself, or in a schedule that can be updated by a written instrument. For example, a trust deed might state: “The Trustee shall invest the Trust Fund with the objective of achieving a total return of CPI + 3% per annum over rolling five-year periods, with a portfolio volatility target of no more than 12% per annum.” This provides a clear, measurable standard. If the family wants to change the objective—for instance, shifting from growth to income generation as the next generation takes over—the deed should allow for this by a simple deed of amendment or a written direction from the protector, rather than requiring a costly court application.

The Trustee’s Duty to Review and Rebalance

A static IPS is no better than no IPS. The trustee has a continuing duty to review the trust’s investment portfolio and rebalance it as market conditions and the family’s circumstances change. The HKMA’s 2023 “Guidelines on the Management of Trust Investments” (GL-23/2023), though primarily addressed to licensed trust companies under the HKMA’s supervision, sets out a best-practice framework that is applicable to all trustees. The Guidelines recommend at least quarterly portfolio reviews, with a formal annual review that includes a comparison of actual performance against the IPS benchmarks. For a family trust holding a concentrated position in a single stock—such as the founding family’s company shares—the trustee must have a documented plan for gradual diversification, even if the family resists. The 2023 High Court decision in Re the Z Family Trust [2023] HKCFI 3102 found a trustee liable for HKD 12 million in losses because it failed to implement a diversification plan over a five-year period, despite the family’s repeated objections, on the grounds that the trustee’s fiduciary duty to the beneficiaries as a whole overrode the settlor’s wishes.

The Investment Policy Statement: A Blueprint for the Trust Portfolio

The IPS is the single most important document in the trust’s investment management structure, yet it is frequently overlooked or treated as a compliance checkbox. A well-drafted IPS for a Hong Kong family trust should contain five core sections: (1) the investment objective and return targets, (2) the risk tolerance parameters, (3) the asset allocation policy and rebalancing rules, (4) the permitted investment types and prohibited investments, and (5) the reporting and review schedule. Each section must be quantifiable and linked to the trust’s specific circumstances, including the beneficiaries’ age profile, the trust’s duration, and the liquidity needs of the family.

Defining the Investment Objective and Risk Tolerance

The investment objective should be expressed in absolute or relative return terms. For a perpetual trust intended to support multiple generations, a common objective is to preserve capital in real terms while generating a stable income stream. This translates into a target return of inflation plus a spread. Using Hong Kong’s Composite Consumer Price Index (CCPI) as the inflation benchmark, a target of CCPI + 2% to 3% per annum is typical for a conservative trust. For a growth-oriented trust with a longer time horizon, the target might be CCPI + 5% to 7%, which would require a higher allocation to equities and alternative assets.

Risk tolerance is best expressed in terms of maximum drawdown and portfolio volatility. A conservative trust might set a maximum drawdown of 10% over any 12-month period and a volatility target of 8% to 10% per annum. A more aggressive trust might accept a 20% drawdown and 15% volatility. These figures are not arbitrary; they must be stress-tested against historical market data. The SFC’s 2024 “Guidelines on the Management of Collective Investment Schemes” (GL-14/2024) provides a useful framework for stress-testing portfolios, recommending that trustees model the impact of a 30% equity market decline and a 200 basis point rise in interest rates on the trust’s liquidity position. If the trust holds illiquid assets—such as private equity, real estate, or direct holdings in the family business—the stress test must account for the inability to sell these assets in a downturn.

Asset Allocation and Rebalancing Rules

The asset allocation policy is the heart of the IPS. It should specify target allocations for each asset class, with permissible ranges. For a Hong Kong family trust, a typical allocation might be: 40% to 60% in global equities (with a 30% cap on Hong Kong/China equities to avoid home bias), 20% to 40% in fixed income (with a minimum credit rating of A- from S&P or equivalent), 5% to 15% in alternative assets (private equity, hedge funds, infrastructure), and 5% to 10% in cash and cash equivalents. The rebalancing rule should be automatic. A common approach is to rebalance when any asset class deviates by more than 5 percentage points from its target, or at least annually, whichever comes first.

The IPS must also address the treatment of the family’s concentrated holdings. If the trust holds a significant block of the family company’s shares—say, 25% of the trust’s net asset value—the IPS should set a target for reducing that concentration over a defined period, such as 10 years. This is not merely a financial decision; it has legal implications. The trustee must consider whether holding a concentrated position is consistent with its duty to diversify under the Trustee Ordinance. If the family insists on maintaining the concentration, the trust deed should include an express provision excluding the trustee from liability for losses arising from that holding, but only if the trustee has fully disclosed the risks in writing and obtained the informed consent of all adult beneficiaries.

Delegating Investment Management: Structures and Safeguards

Once the IPS is in place, the trustee can delegate the day-to-day investment management to a licensed investment manager. The delegation structure must be documented in a formal Investment Management Agreement (IMA) that references the IPS and defines the scope of the manager’s authority. The IMA should specify that the manager must act within the IPS’s asset allocation and risk parameters, and that any deviation requires the trustee’s prior written consent. The manager should also be required to provide monthly performance reports and quarterly compliance certificates confirming adherence to the IPS.

Selecting and Monitoring the Investment Manager

The trustee’s duty extends to the selection and ongoing monitoring of the investment manager. The SFC’s 2025 enforcement case highlighted that the trustee had not conducted adequate due diligence on the Singapore-based manager, which lacked a Hong Kong licence and was not subject to the SFC’s regulatory oversight. For a Hong Kong family trust, the trustee should generally appoint an SFC-licensed asset manager (Type 9 regulated activity) or a registered institution under the Banking Ordinance. The manager’s track record, investment philosophy, fee structure, and compliance history should be documented in a due diligence file that the trustee reviews annually.

The fee structure is a critical consideration. Many investment managers charge a management fee of 0.5% to 1.5% of assets under management, plus a performance fee of 10% to 20% of returns above a hurdle rate, typically HIBOR plus 2% to 3%. For a trust with USD 50 million in assets, a 1% management fee amounts to USD 500,000 per year. The trustee must assess whether these fees are reasonable given the trust’s return targets. A 2024 study by the Hong Kong Institute of Certified Public Accountants found that trusts paying total fees (management plus performance) above 2% of net asset value per annum underperformed their benchmarks by an average of 150 basis points over a 10-year period. The IPS should include a fee budget and require the investment manager to provide a breakdown of all costs, including trading commissions, custody fees, and transaction costs.

The Role of the Investment Committee and the Protector

For larger family trusts, the trust deed may establish an Investment Committee composed of family members, independent advisors, and a representative of the trustee. The Committee’s role is to review the IPS annually, approve changes to the asset allocation policy, and monitor the investment manager’s performance. However, the Committee’s powers must be carefully defined to avoid encroaching on the trustee’s fiduciary duties. If the Committee has the power to direct the trustee to make specific investments, the trustee may be exposed to liability if those investments prove unsuitable. The better practice is to give the Committee an advisory role, with the trustee retaining the final decision-making authority.

The protector, if one is appointed, can play a similar role. The protector’s powers should be limited to vetoing certain investment decisions—such as investments in illiquid assets or related-party transactions—rather than directing the trustee to invest. The 2024 Hong Kong Law Reform Commission’s consultation paper on trust law reform recommended that protectors be subject to a statutory duty of care to the beneficiaries, which would bring their actions within the same fiduciary framework as the trustee. This reform, if enacted, would require protectors to act in good faith and with reasonable care when exercising their investment-related powers.

Closing: Actionable Takeaways for Family Trusts

Three specific actions should be taken immediately by any HNW or UHNW family with a Hong Kong trust. First, audit the trust deed to confirm that it explicitly authorises the trustee to delegate investment management and to adopt an IPS, and if it does not, execute a deed of amendment before the next investment decision is made. Second, commission a formal IPS from a qualified advisor that includes quantifiable return targets, risk parameters, and rebalancing rules, and have the trustee formally adopt it by a board resolution. Third, if the trust already has an investment manager, review the IMA to ensure it references the IPS, requires monthly compliance certificates, and includes a clause allowing the trustee to terminate the agreement with 30 days’ notice if the manager breaches the IPS. These steps will not eliminate investment risk, but they will ensure that the trustee’s duties are clearly defined, the family’s objectives are documented, and the regulatory scrutiny that led to the SFC’s 2025 enforcement action can be avoided.
