Op-ed: Why preparing for old age at 40 is a critical necessity for Vietnam

Editor’s note: This is an opinion piece by Singaporean Darren Chua, who examines Vietnam’s proposed framework for helping people aged 40 and above prepare for old age. Drawing on financial and retirement systems in Singapore and Australia, the author argues that planning for later life should begin well before retirement.

Vietnam’s Ministry of Health recently made headlines by proposing a policy framework to guide citizens aged 40 and above on preparing for old age. The initiative covers healthy living, caregiving, financial planning, and career transitions well before retirement.

While preparing for old age in one’s 40s might sound early, entering mid-life without a retirement blueprint is becoming a major socio-economic risk in rapidly aging Asian societies.

The proposal brings to mind two distinct financial paradigms: Singapore’s Central Provident Fund (CPF) and public housing framework, alongside Australia’s Superannuation regime studied during my university days in Melbourne.

Both prove that preparing for old age at 40 isn't premature, it is a critical necessity.

Old age and the math of inflation

Calculations made at age 40 often fail by estimating needs based on today's cost of living. Over a 20-year runway, inflation fundamentally alters the equation.

Under the Rule of 72, a modest 3.5 percent inflation rate causes baseline living costs to double in roughly 20 years. A comfortable $1,000 monthly budget today will require $2,000 by age 60.

Australia’s Superannuation Guarantee is built around compounding real returns above inflation. The lesson is clear: letting wealth sit in low-yielding cash throughout your 40s and 50s allows inflation to quietly erode 30 to 50 percent of your purchasing power before retirement even begins.

Singapore manages longevity risk by embedding preparation directly into daily economic life via the CPF and HDB housing. The CPF Special Account (SA) pays a guaranteed floor rate of 4.0% p.a., compounding nest eggs ahead of core inflation. Over 70 percent of residents own public HDB flats. Real estate equity naturally hedges against inflation and can later be monetized via lease buybacks or right-sizing.

From 'filial safety net' to personal autonomy

Southeast Asia’s traditional contract—where adult children served as the primary retirement plan—has evolved.

In Singapore, the modern consensus centers on dignified self-reliance. Parents increasingly view it as a duty not to impose financial burdens on their adult children, who face their own mortgages and rising family expenses.

Preparing at 40 builds personal immunity against future financial strain.

Vietnam’s focus on the 40+ demographic is a sharp response to demographic aging. Factoring in a 20-year horizon yields three vital takeaways:

Anchoring financial literacy: Guidance must teach real asset allocation.

Preventive health as wealth: Managing chronic conditions at 45 is the most effective way to flatten a household’s personal medical inflation curve at 65.

Extending earning runways: Subsidized mid-career reskilling allows mature workers to transition into sustainable advisory or flexible roles, extending their productive earning years.

Vietnam's proposal hits on an undeniable truth: the best time to prepare for old age is decades before it arrives, and the only way to beat 20 years of inflation is to start early.
