Diona Teh Li Shian is a Malaysian-Singaporean billionaire heiress whose immense wealth stems from her inherited stake in Public Bank Berhad (KLSE: PBBANK), one of Malaysia's largest banks, and the related insurance firm LPI Capital Berhad. She is the daughter of the late banking magnate Teh Hong Piow (d. 2022), who founded Public Bank in 1965 and chaired it for decades.

Diona, a Singapore citizen, inherited a substantial minority stake in both Public Bank and LPI Capital, making her a major shareholder in the financial services sector. Her role is one of generational stewardship, ensuring the long-term stability and success of the family's assets. Her wealth is secured by the stable, continuous profitability of the banking conglomerate.

Diona Teh Li Shian's career is defined by her role as a major shareholder and guardian of her family's financial legacy. Her wealth is tied to the successful management of Public Bank, which was transformed by her father from a fledgling institution into Malaysia's second-largest bank. The family maintains a controlling influence over the bank's strategy and governance.

In 2024, she gained significant public notice for her investment in high-end real estate in Singapore, purchasing a Good Class Bungalow (GCB) in Tanglin Hill for $70 million (S$93.9 million), one of the city-state's most exclusive residential areas. This massive property acquisition reflects the immense liquidity and diversification of the family's assets outside of Malaysia, cementing her status as a major regional investor.

Diona Teh Li Shian's social impact is structural, stemming from Public Bank's role as a massive financial institution that provides essential banking and credit services to millions of Malaysians. The bank's long-term stability and focus on the mass consumer market is a structural contribution to the national economy.

The family's foundations support various educational and community initiatives, continuing the philanthropic legacy of her father. Her financial move to Singapore is a major indicator of capital flow and investment strategy in the Asia-Pacific region.
