Retirement Annuities and Hong Kong's Ageing Population: The Sustainability of the Public Annuity System

Hong Kong’s Mandatory Provident Fund (MPF) system has accumulated assets exceeding HKD 1.3 trillion as of Q3 2025, yet the territory’s public annuity scheme — the Hong Kong Mortgage Corporation (HKMC) Annuity Plan — has attracted fewer than 15,000 policyholders since its 2018 launch, representing a penetration rate below 0.3% of the eligible 65+ population. This disconnect between accumulated retirement savings and annuity uptake has become a structural concern as Hong Kong’s elderly dependency ratio reaches 29.3% in 2025, up from 19.7% in 2015, according to the Census and Statistics Department’s 2024 Population Projections. The SFC’s 2024 consultation paper on retirement product disclosure standards (SFC, CP-2024-12) and the HKMA’s December 2024 circular on longevity risk management for authorized institutions (HKMA, B10/1C/2024) signal that regulators are now scrutinising the sustainability of Hong Kong’s public annuity framework more closely than at any point since the scheme’s inception.

The Public Annuity Design and Its Structural Limitations

The HKMC Annuity Plan’s Fixed-Rate Mechanism

The HKMC Annuity Plan offers a fixed monthly payout for life, with current rates at approximately 6.0% to 7.5% per annum on the single premium for individuals aged 65 to 80, as published in the HKMC’s 2025 product fact sheet. A male applicant aged 65 paying a HKD 1,000,000 single premium receives approximately HKD 5,800 per month, while a female counterpart receives roughly HKD 5,300 due to longer life expectancy assumptions. The plan caps the single premium at HKD 5,000,000 per policyholder, limiting the maximum monthly payout to approximately HKD 29,000 for a 65-year-old male. This fixed-rate structure exposes the HKMC — and by extension the Exchange Fund, which backstops the scheme — to significant longevity risk, as the HKMA’s 2024 Longevity Risk Assessment Report (HKMA, LRAR-2024) estimates that Hong Kong’s 65-year-old population will see life expectancy increase by an additional 2.3 years by 2045 relative to 2020 baseline assumptions.

The Take-Up Problem: Why Retirees Are Not Buying

As of June 2025, the HKMC Annuity Plan has sold approximately 14,800 policies, representing a total premium inflow of HKD 12.4 billion — a fraction of the HKD 1.3 trillion in MPF assets available for decumulation. The SFC’s 2024 Retail Investor Survey (SFC, RIS-2024) found that 72% of respondents aged 55-65 cited “loss of control over the lump sum” as the primary barrier to annuity purchase, while 58% cited “insufficient payout relative to inflation expectations.” Hong Kong’s average Consumer Price Index (CPI) inflation of 2.1% per annum from 2020-2025, combined with the HKMC annuity’s fixed nominal payout, means that a policyholder receiving HKD 5,800 per month in 2025 will have real purchasing power of approximately HKD 4,700 by 2035, assuming constant 2% inflation — a real-terms reduction of 19%.

The Guaranteed Portion vs. Market-Linked Alternatives

The HKMC Annuity Plan’s payout is 100% guaranteed by the Exchange Fund, with no market-linked component. This contrasts with the Mandatory Provident Fund Schemes Authority’s (MPFA) 2024 consultation on default investment strategy (DIS) enhancements (MPFA, CP-2024-03), which proposed introducing a “decumulation phase” option that would allow scheme members to gradually withdraw MPF savings through a systematic withdrawal plan rather than a lump sum. The MPFA’s proposal, if implemented in 2026, would create a direct competitor to the HKMC annuity — one that allows retirees to retain control of their capital while generating income through a mix of bonds and equities, rather than surrendering the principal for a fixed life payout.

Demographic Pressures and the Longevity Risk Calculus

The 65+ Population Growth Trajectory

The Census and Statistics Department’s 2024 Population Projections (C&SD, PP-2024) project that Hong Kong’s population aged 65 and over will increase from 1.62 million in 2025 to 2.31 million by 2045, representing a compound annual growth rate of 1.8%. The old-age dependency ratio — defined as the number of persons aged 65+ per 1,000 persons aged 15-64 — is projected to rise from 293 in 2025 to 491 by 2045. This demographic shift directly impacts the HKMC Annuity Plan’s actuarial sustainability, as each cohort of new annuitants will, on average, collect payments for longer than the previous cohort. The HKMA’s 2024 Longevity Risk Assessment (HKMA, LRAR-2024) calculated that a 1-year increase in average life expectancy for the HKMC annuity pool would increase the scheme’s liability by approximately HKD 1.8 billion, assuming current premium levels and payout rates.

The Fiscal Implications for the Exchange Fund

The HKMC Annuity Plan is backed by the Exchange Fund, which held total assets of HKD 4.2 trillion as of December 2024 (HKMA, Annual Report 2024). The HKD 12.4 billion in annuity premiums represents 0.3% of the Exchange Fund’s total assets, suggesting that the scheme’s current scale poses minimal fiscal risk. However, the HKMA’s stress test scenario for the annuity scheme — published in the 2024 Longevity Risk Assessment — assumed a worst-case scenario of 50,000 policyholders by 2030, which would increase the Exchange Fund’s contingent liability to approximately HKD 45 billion. Under this scenario, the HKMA estimated that the scheme would require an additional HKD 3.2 billion in capital reserves to maintain a 99.5% solvency probability, based on the latest actuarial assumptions for Hong Kong mortality improvements.

The Gender Gap in Annuity Pricing

The HKMC Annuity Plan uses gender-distinct pricing, with female applicants receiving approximately 8-10% lower monthly payouts than male applicants of the same age and premium amount. For a HKD 1,000,000 premium at age 65, a male receives HKD 5,800 per month while a female receives HKD 5,300 — a difference of HKD 500 per month, or HKD 6,000 per year. The SFC’s 2024 Gender and Investment Report (SFC, GIR-2024) noted that women in Hong Kong hold approximately 58% of MPF accounts but only 34% of annuity policies, suggesting that the pricing differential may be contributing to lower female uptake. The Equal Opportunities Commission’s 2024 submission to the Legislative Council’s Panel on Financial Affairs (EOC, LC Paper No. CB(1)1234/2024) raised concerns that gender-distinct annuity pricing may contravene the Sex Discrimination Ordinance (Cap. 480), though the HKMC has maintained that the differential is actuarially justified.

Cross-Market Comparisons: Singapore’s CPF LIFE and Taiwan’s National Annuity

Singapore’s CPF LIFE: A Mandatory Annuity Model

Singapore’s Central Provident Fund (CPF) LIFE scheme, launched in 2009, provides a compulsory annuity for all CPF members who reach age 65 with at least SGD 60,000 in their Retirement Account. As of 2024, approximately 1.2 million Singaporeans were covered by CPF LIFE, with monthly payouts ranging from SGD 1,200 to SGD 2,200 depending on the chosen plan and retirement sum. The CPF LIFE scheme is funded through a combination of member contributions and government subsidies, with the Singapore government contributing SGD 1.5 billion in 2023 to support the scheme’s sustainability. Unlike Hong Kong’s voluntary HKMC annuity, CPF LIFE’s mandatory nature ensures near-universal coverage among the eligible population, with a take-up rate exceeding 95% — compared to Hong Kong’s 0.3%.

Taiwan’s National Annuity: A Pay-As-You-Go System

Taiwan’s National Pension Insurance (國民年金保險), launched in 2008, provides a universal annuity for all citizens aged 25-65 who are not covered by other social insurance schemes. As of 2024, the scheme covered 3.4 million participants, with monthly payouts averaging TWD 3,800 (approximately HKD 950) per recipient. The scheme operates on a pay-as-you-go basis, with a contribution rate of 10% of the insured person’s monthly income, split between the insured (60%) and the government (40%). Taiwan’s National Pension has faced sustainability challenges similar to those confronting Hong Kong, with the scheme’s insolvency date projected for 2038 based on the 2023 actuarial report — a projection that assumes no changes to contribution rates or benefit levels.

The Structural Advantage of Mandatory Participation

Both Singapore’s CPF LIFE and Taiwan’s National Pension share a common structural feature that Hong Kong’s HKMC annuity lacks: mandatory or near-mandatory participation. Singapore’s CPF LIFE achieves a 95% take-up rate through automatic enrolment at age 65, with opt-out permitted only under specific hardship conditions. Taiwan’s National Pension achieves 82% coverage through compulsory participation for all eligible non-employed citizens. Hong Kong’s voluntary model, by contrast, has achieved less than 0.3% penetration among the eligible 65+ population. The MPFA’s 2024 consultation on decumulation options (MPFA, CP-2024-03) explicitly referenced both Singapore’s and Taiwan’s models as potential benchmarks for Hong Kong, though the consultation document noted that “any mandatory annuity component would require significant legislative amendments and public consensus.”

The Private Annuity Market and Regulatory Developments

The SFC’s 2024-2025 Disclosure Reforms

The SFC’s December 2024 consultation on retirement product disclosure standards (SFC, CP-2024-12) proposed requiring all annuity providers to present a standardised “Projected Real Income” figure, calculated using the HKMA’s official inflation forecast and a life expectancy assumption based on the Census and Statistics Department’s most recent mortality tables. The proposed disclosure regime would require insurers to show the nominal payout, the inflation-adjusted payout at years 10, 20, and 30, and the probability that the insurer will be able to meet its obligations under a 1-in-200-year stress scenario. The SFC’s consultation paper noted that “current disclosure practices vary significantly across providers, with some presenting only nominal payouts without any inflation adjustment, potentially misleading consumers about the real purchasing power of their annuity income.”

The Insurance Authority’s 2025 Solvency Requirements

The Insurance Authority (IA) of Hong Kong implemented the Risk-Based Capital (RBC) regime for insurers effective January 2025, replacing the previous rule-based solvency framework. Under the RBC regime, annuity providers must hold capital reserves that reflect the longevity risk of their policyholders, calculated using the IA’s prescribed mortality improvement assumptions. The IA’s 2025 Guideline on Longevity Risk (GL-2025-12) requires insurers to use a mortality improvement assumption of 1.5% per annum for the first 20 years and 1.0% per annum thereafter, based on Hong Kong’s historical mortality improvement rates from 2000-2023. This represents a more conservative assumption than the 0.8% per annum used under the previous solvency framework, meaning that annuity providers will need to hold approximately 12-15% more capital for new annuity business written after January 2025.

The Private Annuity Product Landscape

As of mid-2025, Hong Kong’s private annuity market offers approximately 28 products from 14 insurers, with payouts ranging from 4.5% to 8.2% per annum for a 65-year-old male paying a HKD 1,000,000 single premium. The highest-yielding products — typically from smaller insurers with lower expense ratios — offer payouts of 7.8-8.2% per annum, compared to the HKMC’s 6.0-7.5% range. However, these private annuities carry credit risk: the IA’s 2024 Annual Report noted that two Hong Kong insurers have annuity portfolios with a weighted-average credit rating of BBB-, meaning that a single-notch downgrade could trigger capital adequacy concerns. The SFC’s 2024 consultation on disclosure standards (SFC, CP-2024-12) proposed requiring all annuity providers to disclose their credit rating and the impact of a one-notch downgrade on policyholder payouts, a requirement that would apply to both private and public annuity products.

Actionable Takeaways for Retirees and Advisors

1. The HKMC Annuity Plan’s fixed nominal payout will lose approximately 19% of its real purchasing power over 10 years at 2% inflation, making it unsuitable as a sole retirement income source for anyone with a life expectancy exceeding 15 years.

2. Singapore’s CPF LIFE achieves 95% coverage through mandatory participation, while Hong Kong’s voluntary HKMC annuity has achieved less than 0.3% penetration — a structural failure that the MPFA’s 2024 decumulation consultation may address through automatic enrolment proposals in 2026.

3. The IA’s 2025 RBC regime increases capital requirements for annuity providers by 12-15%, which will likely compress payout rates by 30-50 basis points for new policies written after January 2025.

4. Private annuity products offering payouts above 8.0% per annum warrant close scrutiny of the underlying credit rating, as the IA’s 2024 Annual Report identified two insurers with BBB- rated annuity portfolios that face capital adequacy risk under the new RBC framework.

5. Retirees should consider a laddered annuity strategy — purchasing smaller annuities at ages 65, 70, and 75 — to mitigate both inflation risk and longevity risk, a structure that the SFC’s 2024 disclosure reforms (SFC, CP-2024-12) are designed to make more transparent for consumer comparison.
