Tan Su Shan
Tan Su Shan (born 1967) is a Singaporean banker and business executive who has served as Chief Executive Officer and Director of DBS Group, Southeast Asia's largest bank, since March 28, 2025. She is the first woman to lead DBS in its history and only the second woman to head a Singaporean bank, following OCBC's Helen Wong in 2021.
With over three decades of experience in the financial services industry spanning institutional equity sales, private banking, and consumer banking, Tan has built a reputation for transforming business units and championing the use of data analytics and artificial intelligence in banking. Her career trajectory from losing her job at 26 during the collapse of Barings Bank to leading a $600 billion financial institution represents one of the most remarkable comeback stories in Asian banking.
Early life and family background
Tan Su Shan was born in Singapore in 1967 into a family that valued education and female empowerment despite the era's social norms. Her mother was career-oriented and managed the household, providing an early model of balancing professional and family responsibilities. Tan's grandmother was a particularly formative influence—widowed during the Japanese occupation, she raised seven successful children despite never receiving formal education herself.
"She grew up in a time when women were not educated," Tan has recounted about her grandmother. Despite being denied schooling, her grandmother taught herself to read and insisted that her daughters, including Tan's mother, excel academically, secure employment, and achieve financial independence. This generational emphasis on education and self-sufficiency deeply shaped Tan's approach to her own career and her advocacy for women in finance.
Her sister, Tan Sulian, serves as a Senior Director at Savills Singapore, demonstrating the family's continued presence in Singapore's business community.
Education
Tan earned her master's degree in Politics, Philosophy, and Economics (PPE) from the University of Oxford, one of the most prestigious academic programs in the world. The rigorous interdisciplinary curriculum, which has produced numerous heads of state and business leaders, provided Tan with analytical frameworks that she has applied throughout her banking career.
During her university years, Tan interned at DBS—a connection that would prove consequential decades later when she returned to the bank and eventually rose to lead it.
Career
Early years at ING Barings
After graduating from Oxford, Tan spent eight years at ING Baring Securities in institutional equity sales. She worked in key financial hubs including London, Tokyo, and Hong Kong, developing expertise in Asian capital markets and building relationships with institutional investors across the region.
Her time at Barings came to an abrupt end when the bank collapsed in February 1995 following the unauthorized trading activities of Nick Leeson in Singapore. At age 26, Tan found herself suddenly unemployed. The personal toll was devastating—her Hong Kong landlord evicted her, doubting her ability to pay rent, and her long-term boyfriend broke up with her the same week.
"At the time, I felt that life was really challenging," Tan later recalled. Rather than viewing this period as defeat, she credits these setbacks with forging her "inner strength" and resilience. The experience taught her that career setbacks, however painful, could be overcome.
Morgan Stanley (1997–2005, 2008–2010)
In 1997, Tan joined Morgan Stanley in Singapore as an Executive Director, serving as an investment adviser to high-net-worth families, corporations, and institutions across the region. Her dedication to the role was legendary—when she was in labor with her first child in 1999, she had a Bloomberg terminal set up in her hospital room to monitor currency movements between the US dollar and Japanese yen that affected her clients' positions.
This anecdote, frequently cited in profiles of Tan, became emblematic of her intense commitment to client service while also sparking debates about work-life balance in high-pressure financial careers.
Citigroup (2005–2008)
Tan moved to Citi Private Bank in 2005, where she rapidly rose to become Regional Head for Singapore, Malaysia, and Brunei. She was responsible for the private bank's overall business in these markets and served as a board director of Citi Trust Singapore. Her success in building Citi's private banking presence in Southeast Asia cemented her reputation as a wealth management specialist.
Return to Morgan Stanley (2008–2010)
In May 2008, Tan returned to Morgan Stanley as Head of Private Wealth Management for Southeast Asia. However, her tenure coincided with the global financial crisis, which dramatically reshaped the wealth management industry. Despite the challenging environment, she continued building client relationships and developing the firm's regional presence.
DBS Group (2010–present)
Piyush Gupta, who became DBS CEO in 2009, recruited Tan in 2010 to scale and modernize the bank's wealth management franchise. At the time, DBS had a decidedly different reputation from today. "We were the worst bank," Tan later recalled. "Worst bank for customer service, worst bank for the longest queues, worst bank for product."
Transforming wealth management
Tan applied her private banking expertise to transform DBS's wealth management business. She was promoted in 2013 to head both Consumer Banking and Wealth Management, giving her responsibility for the bank's entire retail franchise. Under her leadership, DBS became Asia's top private bank and a digital banking leader.
Her relentless focus on customer experience and enthusiasm for leveraging data and artificial intelligence distinguished her approach. She championed A/B testing and data analytics to optimize customer interactions, an approach that has since generated hundreds of millions of dollars in value for the bank.
Rise to institutional banking
In August 2024, Tan was appointed Deputy CEO while simultaneously serving as Group Head of Institutional Banking. This role gave her end-to-end command of DBS's core engines—consumer banking, wealth management, and institutional banking—effectively grooming her for the top position.
CEO appointment
On August 15, 2024, DBS announced that Tan would succeed Piyush Gupta as CEO on March 28, 2025. The announcement made her the first woman to lead DBS in its history. The transition came at a pivotal moment, with Tan taking the helm just days before significant geopolitical disruptions from US trade policy.
Leadership at DBS
AI and technology strategy
Tan has made artificial intelligence central to her leadership vision. When her CEO appointment was announced, a board member texted her saying "even the CEO's job will be replaced, or can be replaced, by AI"—a friendly reminder that she applies to the entire organization.
Under her direction, DBS has tracked that AI and data analytics delivered approximately 750 million Singapore dollars in economic value in 2024, with projections reaching 1.1 to 1.2 billion Singapore dollars in 2025. However, this technological transformation has also led to workforce adjustments—in February 2025, DBS announced plans to reduce approximately 4,000 contract and temporary staff over three years while adding 1,000 new roles focused on artificial intelligence.
Navigating geopolitical challenges
Tan assumed the CEO role during a period of intense geopolitical uncertainty. Her public advice to businesses facing trade tensions has emphasized diversification: "Diversify your supply chains, diversify your markets, diversify your funding sources." This pragmatic approach reflects her recognition that DBS's pan-Asian footprint across 19 countries requires nimble responses to rapidly shifting trade and political dynamics.

Personal life
Tan Su Shan has been married to Chris for over 25 years. They have two children: a daughter named Talisha and a son named Kai. Approximately 15 years ago, Chris established a foundation focused on assisting underprivileged communities in Asia. The family participates in annual humanitarian missions together, including bringing medical teams from KK Women's and Children's Hospital to Cambodia to train local healthcare workers. These missions have contributed to reducing infant mortality rates in the region.
Beyond philanthropy, Tan is passionate about tap dancing and playing the piano. She has cited Margaret Thatcher as a figure she admires for her tenacity and commitment to her convictions, regardless of political controversy.
Controversies and challenges
Technology stability concerns
DBS faced regulatory scrutiny over technology issues prior to Tan's CEO tenure. The Monetary Authority of Singapore (MAS) imposed a six-month pause on non-essential activities from November 1, 2023 to April 30, 2024. During this period, the bank could not acquire new business ventures or make non-essential IT changes. While these issues predated her appointment as CEO, addressing technology stability has been identified by analysts as a priority for her leadership.
Workforce reduction announcements
The February 2025 announcement that DBS would cut approximately 4,000 contract and temporary staff—roughly 50% of over 8,000 such employees—over three years drew attention to the human impact of AI adoption in banking. While the bank simultaneously announced 1,000 new AI-focused roles, the net reduction raised questions about how technological transformation affects employment, particularly for non-permanent workers.
Bloomberg terminal hospital incident
The story of Tan having a Bloomberg terminal set up in her hospital room during labor has been cited both as evidence of her extraordinary dedication and as a cautionary tale about work-life imbalance in high-pressure finance careers. Tan herself has been matter-of-fact about the incident, reflecting the intensity she brought to her work while building her career.
