In March 2025, Tan Su Shan became CEO of DBS Group — the first woman to lead Southeast Asia’s largest bank, an institution with a market capitalisation above US$100 billion. Her path there is notable for its length and consistency. Born in 1968 and educated at Oxford in politics, she began her banking career at Morgan Stanley’s Singapore office in 1997, rising to executive director before moving to Citi, where she served as a regional head covering Brunei, Malaysia, and Singapore.
She joined DBS in 2010 as Managing Director and Group Head of Wealth Management, and from there her responsibilities steadily broadened. She went on to lead consumer banking and, later, the bank’s corporate and institutional banking division — an unusually wide sweep of the business that gave her intimate knowledge of DBS from the perspective of individual customers, wealthy clients, and large corporates alike. Across more than fifteen years at the bank, and over 35 years in the industry overall, she became known as a specialist in wealth management and institutional banking who understood the institution from multiple angles before ever taking its helm.
That breadth matters. Running a bank the size of DBS is not simply a matter of setting strategy from the top; it requires understanding how retail, wealth, and institutional businesses interact, how technology is reshaping each of them, and how a regional bank competes with global giants. Tan’s career effectively served as a long apprenticeship for exactly that challenge, and her appointment was widely read as a natural progression rather than a gamble.
Her rise has also carried symbolic weight well beyond DBS. As the first woman to lead the bank, and as a leader who worked her way up through nearly every major division, she has become a prominent example of homegrown Asian banking talent reaching the very top. She has appeared at the top of influential rankings recognising powerful women in business, and her leadership is closely watched as a bellwether for how established Asian banks navigate digital transformation and regional expansion.
