Rethinking Wealth Planning for Longevity in the APAC Region

Asia is ageing faster than any region in modern history, and it is doing so before most of its economies have finished getting rich. That single fact is quietly forcing a rewrite of how wealth is planned, protected, and passed on across the region, from mass-affluent households in provincial Thailand to the family offices multiplying in Singapore.

A demographic shift without historical precedent

The old template, save through your working years, retire at a fixed age, draw down a pension for a decade or two, was built for a world with shorter lifespans and simpler family structures. It does not fit a region where a 60-year-old today can reasonably expect another three to four decades of life, many of them active, some of them requiring expensive care, and none of them covered by the pay-as-you-go pension systems that cushioned earlier generations in the West.

Thailand is the clearest illustration of the pressure building across the region. The country crossed the threshold into an “aged society” in the early 2020s, when more than a fifth of its population reached 60 or older, and it is now on a trajectory toward “super-aged” status, with roughly 30 percent of Thais expected to be 60 or above by the early 2030s. What makes the Thai case distinctive, and instructive for much of the rest of ASEAN, is the sequencing: the country is ageing at a fraction of the per-capita income level that Japan, South Korea, or the wealthier OECD economies had reached when they crossed the same demographic markers.

Development economists have taken to calling this “growing old before growing rich,” and it means the usual policy levers, generous public pensions, comprehensive long-term-care insurance, extensive institutional elder care, are simply not funded at the scale the demographics require. A falling fertility rate, now near 1.2 births per woman, and continued outward migration of working-age Thais compound the strain on family-based care models that previous generations relied on by default.

Thailand is not an outlier so much as an early mover. Singapore, Hong Kong, China, and Japan are all navigating versions of the same transition, and the World Economic Forum has described the region as entering “the longevity era” earlier and faster than anywhere else in the world, with financial literacy and retirement preparedness lagging the pace of the demographic change. The practical consequence for households, and for the advisors, insurers, and bankers serving them, is that a strategy built around a single retirement date and a static asset allocation is no longer adequate. Wealth planning is shifting from a one-time retirement calculation into something closer to a continuous, multi-decade exercise shaped as much by health trajectories and family obligations as by market returns.

Why the old retirement model no longer holds

Three structural pressures are converging to force this shift. The first is simple arithmetic: longer lifespans mean retirement savings, however carefully accumulated, have to stretch across more years of spending without a matching increase in the working years used to build them. The second is healthcare cost inflation, which in most APAC markets is rising faster than general inflation and faster than pension income, front-loading risk into precisely the years when income is fixed and health needs are climbing.

The third is the erosion of the informal safety net. Multi-generational households, in which adult children absorbed the bulk of eldercare costs and labour, are shrinking as urbanisation, smaller family sizes, and cross-border migration pull working-age adults away from ageing parents. Where that safety net used to substitute for formal financial planning, its retreat is now exposing a planning gap that markets and regulators are only beginning to address.

Industry research from Manulife and other regional insurers has picked up on a related shift in how people in the region actually define a successful retirement. Increasingly, the benchmark is not simply years lived but financial independence sustained across those years, the ability to maintain a chosen lifestyle without becoming a burden on family, for the full span of a longer life. That reframing has direct implications for advisors: a plan that gets a client to a retirement date is no longer the deliverable. The deliverable is a plan that holds up for thirty-plus years of uncertain healthcare needs, inflation, and market cycles.

The regional wealth-management response

Where the demographic pressure is most visible in policy debates, the financial response is most visible in the region’s private banking and family office ecosystem. Singapore has emerged as the undisputed hub for that response, its single family office count having grown roughly fourfold since 2020, with regional estimates placing more than 1,500 to 2,000 such structures now registered under the city-state’s tax-incentive schemes.

That growth is not incidental to the longevity story, it is substantially driven by it: a wealth transfer across the Asia-Pacific region estimated at close to six trillion dollars by the end of the decade is pushing first- and second-generation wealth holders to formalise structures for succession, tax efficiency, and multi-generational governance well ahead of when their Western counterparts historically did so, precisely because Asia’s wealthy households skew younger and are still in wealth-building rather than pure wealth-preservation mode.

Thailand sits adjacent to that hub rather than at its centre, but the effects are visible domestically. Bangkok’s ultra-high-net-worth population is projected to grow faster than any other city in Southeast Asia through the end of the decade, and the city’s broader high-net-worth segment is expanding on a similar trajectory, with total private wealth in the country on course to approach the trillion-dollar mark within a few years.

That growth is drawing international private banking expertise onshore, including partnerships pairing global wealth managers with Thai banks to build out advisory capacity for clients who increasingly need cross-border, multi-jurisdiction planning rather than a single domestic savings product.

What a longevity-adjusted plan actually looks like

The practical shift in advisory practice follows a few consistent threads across the reports coming out of Singapore, Hong Kong, and the wider region this year. Asset allocation is moving away from the traditional glide path that mechanically de-risks a portfolio as a client approaches a fixed retirement age, toward a blend that keeps a meaningful growth allocation running well into the later decades of life, on the logic that a 65-year-old with a thirty-year horizon still needs equity-like returns to avoid outliving their capital.

Risk-pooling instruments, annuities, long-term-care riders, and critical-illness coverage with living benefits, are being positioned less as niche products and more as core components of a longevity plan, precisely because savings and market returns alone cannot reliably absorb the tail risk of an extended and possibly costly old age. Bank of Singapore’s outlook for the year ahead frames the sector’s opportunity in similar terms, expecting insurers to extend policy age limits and banks to bundle wealth advice with practical elder-care services as the “silver economy” becomes a mainstream client segment rather than a specialty one.

For the mobile and cross-border wealth that characterises much of TBN’s readership, expatriates, dual-national families, and Thailand-based investors with assets spread across several jurisdictions, the longevity shift adds a further layer of complexity around structuring. Cross-border trusts, portable insurance-based savings vehicles, and family office or family investment company structures are increasingly used not just for tax efficiency but to ensure that healthcare and succession arrangements travel with a family across borders rather than being tied to the rules of a single country. That is particularly relevant given how mobile global wealth has become: cross-border relocation of high-net-worth individuals is running at record levels this year, and a growing share of that movement is explicitly built around holding residence rights and assets in more than one jurisdiction rather than settling permanently in one.

A growing opportunity for APAC wealth managers

The longevity challenge is also creating a significant commercial opportunity.

PwC expects assets under management across APAC to reach approximately US$34.5 trillion by 2030, up from US$23.2 trillion in 2024. The firm estimates that the region could generate US$47 billion in additional annual asset and wealth-management revenues by the end of the decade.

But capturing this opportunity will require more than traditional investment products.

Wealth managers will need solutions that combine investment management with retirement-income planning, insurance, estate planning and increasingly sophisticated digital services.

The opportunity is particularly relevant to regional financial centres such as Singapore and Hong Kong, which are already serving as hubs for cross-border wealth and family-office activity.

For Thailand, the opportunity is equally significant. The country can develop a broader ecosystem around retirement finance, private wealth, healthcare, senior living and the emerging silver economy.

The stakes for Thailand’s wealth-management sector

For Thailand specifically, the longevity shift is arriving alongside, and partly reinforcing, the broader wealth boom already reshaping Bangkok’s property and private banking markets. A population that is both getting older and, at the upper end, getting significantly wealthier is a rare combination, and it is pulling international private banks, insurers, and family office service providers toward a market that a decade ago would have been considered secondary to Singapore or Hong Kong. How well the country’s regulators and financial institutions adapt housing, healthcare financing, and wealth-transfer infrastructure to that combination, rather than treating the ageing population and the wealth boom as separate stories, will likely determine whether Thailand captures its share of a longevity economy that regional analysts expect to grow from roughly three trillion dollars in 2025 to well over five trillion by the middle of the next decade, or cedes that opportunity to hubs that move faster.

What is clear is that the conversation has already moved past whether Asia’s wealth planning needs to change. The demographic and capital-flow data leave little room for that debate. The open question, for advisors, institutions, and households alike, is how quickly the region’s financial infrastructure, from Bangkok’s private banks to Singapore’s family office registries, can catch up with a life expectancy curve that has already moved.
