What’s the largest Singaporean family office by AUM?

Our familyofficehub.io research team has identified that Wee Investments Pte Ltd is the largest Singaporean family office, with assets under management estimated in the multi-billion-dollar range. The familyofficehub.io team estimates that the total assets managed by Wee Investments Pte Ltd, in combination with directly controlled vehicles, easily exceed $5–7 billion, positioning it as the preeminent Singaporean family office both in historical influence and financial scale.

How does the Wee family invest?

The Wee family, one of Singapore’s most influential dynasties, traces its wealth back to Wee Cho Yaw, a banking titan who served as the former chairman and CEO of United Overseas Bank (UOB). Over several decades, the family established itself at the helm of some of Singapore’s most prominent financial and real estate institutions.

At the center of the family’s investment activities is Wee Investments Pte Ltd, the single family office of the Wee family. Serving as the private holding and investment arm, the entity consolidates significant stakes in publicly listed companies, notably in UOB and UOL Group, and steers the family’s broader strategic allocations.

Wee Investments holds a substantial minority position in UOB, Singapore’s third-largest bank, and remains one of the largest individual shareholder blocs. The family also retains a commanding interest in UOL Group, a leading real estate and hospitality company. Beyond equities, the Wee family is actively involved in private real estate investments and regional expansion projects, often in collaboration with affiliated entities.

An important affiliated entity is Kheng Leong Company, which functions as the family’s real estate development and investment platform. While distinct from Wee Investments Pte Ltd, it shares close ownership and governance ties with the family and has a global portfolio encompassing residential, commercial, and industrial assets.

Under the stewardship of the next generation — including Wee Ee Cheong (current UOB CEO) and other family directors — the investment strategy remains conservative yet opportunistic. The family continues to prioritize long-term value creation through core financial holdings, property ventures, and strategic diversification in Asia-Pacific and beyond.

Alternative candidates for the Singaporean family office ranking by AUM

Our team also considered several other prominent family offices in Singapore for the top position. The Ng family (of Far East Organization and Sino Group) operates through Kuang Ming Investments, a substantial private vehicle. Still, their wealth is primarily embedded in operating companies rather than managed via a traditional family office model.

Goh Cheng Liang, majority owner of Nippon Paint, channels his holdings through Wuthelam Holdings, which functions as a hybrid corporate holding and family office, with investments spanning Asia and Japan. While the scale is significant, Wuthelam acts more as a strategic control entity than an active asset allocator.

The Kwee family, owners of Pontiac Land Group, established the Kwee Investment Office in Singapore to manage their wealth globally. It plays a highly structured role in deploying capital into real estate and alternative assets, but based on available public information, the scale is smaller than Wee Investments.

Other candidates include AT Capital Group (Arvind Tiku), Clermont Group (Richard Chandler), and Ivanhoe Capital (Robert Friedland), each representing substantial family-controlled investment arms. However, most of these reflect internationally diversified operations or specialized portfolios rather than the broad, intergenerational scope maintained by the Wee family’s family office.

As such, Wee Investments Pte Ltd remains, by our analysis, the largest and most traditional single family office in Singapore, combining active ownership, diversified investments, and multigenerational continuity.
