What is longevity risk? Outliving your retirement savings
Long life is a blessing, but in retirement planning it brings a real problem — 'longevity risk': if you live longer than expected, your savings may not last. Hong Kong is one of the world's longest-living places, with life expectancy of about 88 for women and 83 for men, and a retirement that can span 20–30 years, so 'living too long' must be built into the plan.
What is longevity risk?
Longevity risk is the risk that your actual lifespan exceeds expectations and your retirement savings run out while you're alive. Many plan to the 'average' life expectancy, but average means about half will live longer; planning only to the average risks a shortfall in later life. The core issue isn't a big enough total — it's whether income 'lasts for life'.

Why is it often underestimated?
- Planning to average life expectancy: about half will live longer than average.
- Ignoring inflation: the longer the horizon, the more inflation erodes purchasing power.
- Healthcare and care: medical and long-term care costs tend to rise in old age.
- Withdrawing too fast: taking too much early can leave you short later.
With Hong Kong's high life expectancy and long retirement, longevity risk deserves attention.
How to address longevity risk
- Lifetime annuity: lock in 'income for life' with an annuity to hedge longevity risk.
- Income layering: cover essentials with steady income, keep the rest for growth and flexibility.
- Inflation protection: keep growth or inflation-linked assets in the mix.
- Conservative withdrawals and regular review: control the drawdown pace and review yearly.
Annuities are a common longevity hedge; see annuity planning and retirement cash flow.
Build longevity into the plan
Rather than 'do I have enough to retire', ask 'if I live to 95, is my income still enough'. Planning to a longer horizon with conservative inflation assumptions, and locking the base with a lifetime annuity, makes retirement more secure.

Frequently asked questions
What is longevity risk?
The risk of living longer than expected in retirement and your savings running out. Planning to 'average' life expectancy can underestimate it, since about half live longer; the core is whether income 'lasts for life', not how big the total is.
To what age should Hong Kong people plan?
Hong Kong life expectancy is high — about 88 for women and 83 for men, and many live longer. Plan to a longer horizon (e.g. beyond 90) with conservative assumptions, building in 'living too long'.
How do I hedge longevity risk?
A common approach is locking 'income for life' with a lifetime annuity to cover essentials, combined with income layering, inflation-protection assets, conservative withdrawals and regular review for lasting income.
Do annuities fully solve longevity risk?
Annuities are an effective hedge, providing lifetime income, but usually need to be combined with other assets for flexibility, growth and inflation protection — not a single solution.
