Imagine this: every day, an average of 89 people around the world officially enter the exclusive club of individuals with a net worth above US$30 million. They are known as ultra-high-net-worth individuals (UHNWI), and an increasing number of them are choosing Southeast Asia as their base.
Data from The Wealth Report 2026 by Knight Frank highlights a significant surge in the number of UHNWI in the region, with Singapore emerging as its main epicenter.
Between 2021 and 2026, the global UHNWI population grew from 551,435 to 713,626. This means 162,191 new ultra-wealthy individuals were added over the past five years. The United States accounted for 41 percent of that growth, followed by China at 17 percent.
Yet behind the dominance of these two economic giants, Southeast Asia has quietly positioned itself as the fastest-growing wealth region in the world.
Singapore: Small but Dense with Billionaires
Few countries of Singapore’s size have managed to more than double their billionaire population within five years.
In 2021, Singapore had 28 billionaires. By 2026, that number had surged to 63, and it is projected to reach 85 by 2031. The number of UHNWI in Singapore also grew by 54.5 percent, from 4,642 individuals in 2021 to 7,171 in 2026.
Knight Frank projects this figure will surpass 10,495 by 2031, placing Singapore among the world’s top 10 for UHNWI growth over the next five years.
Singapore’s appeal goes beyond infrastructure or quality of life. Its geographic position at the crossroads of Southeast Asia, China, India, and Australia makes it a strategic hub for wealthy investors seeking access to high-growth markets while keeping assets in a neutral and internationally trusted jurisdiction.
Another notable trend is the rise of globally mobile UHNWI adopting a “dip-in, dip-out” lifestyle, spending fewer than 90 days per year in any single location.
Singapore, with its strong luxury rental market, has become one of the preferred destinations for this lifestyle. Over the past five years, prime rental prices in Singapore have increased by 48 percent.
In the property sector, prime residential prices rose by 7.9 percent in the last 12 months, marking one of the strongest growth rates in recent years.
Southeast Asia: A New Wave of Wealth Just Beginning to Break
If Singapore is the center of gravity, then Southeast Asia is the region now radiating some of the most dynamic wealth growth in the world.
Indonesia leads projected UHNWI growth across Asia-Pacific. From 3,833 individuals in 2026, the number is expected to surge to 6,966 by 2031, marking an 81.7 percent increase over five years.
Viet Nam follows with projected growth of 59 percent, rising from 1,233 to 1,960 UHNWI. Philippines also posts strong numbers, growing 48.9 percent from 1,910 to 2,844 individuals.
UHNWI Growth in Southeast Asia
| Country | UHNWI 2026 | UHNWI 2031 (F) | Growth |
|---|---|---|---|
| Singapore | 7,171 | 10,495 | 46.4% |
| Indonesia | 3,833 | 6,966 | 81.7% |
| Thailand | 2,853 | 3,582 | 25.6% |
| Philippines | 1,910 | 2,844 | 48.9% |
| Malaysia | 1,566 | 1,881 | 20.1% |
| Viet Nam | 1,233 | 1,960 | 59% |
According to Craig Shute, CEO of Asia-Pacific at Knight Frank, the expansion of wealth across emerging markets in the region reflects a deeper economic shift, driven by entrepreneurship, maturing capital markets, and domestic economic expansion.
This trend is also visible in cross-border investment flows. In 2025, cross-border commercial real estate investment by high-net-worth individuals in Asia-Pacific surged to its highest level since 2019.
Singapore has been one of the key beneficiaries, ranking among the top 10 global cities for cross-border capital inflows, with a total of S$4.2 billion.
Total real estate investment sales in Singapore reached a record S$40.5 billion in 2025. In just the first three months of 2026, transaction volume had already hit S$16.7 billion.
In a region that continues to move at speed, one thing is clear: Southeast Asia is no longer just a complementary investment destination. It has become a primary arena for global wealth creation and accumulation, with Singapore at the forefront.
