Our Leadership

In an environment that's as complex as Asia, you can always be assured that there's a complete team of experts here for you.


Shee Tse Koon

As a teenager, Tse Koon wanted to be a doctor. Until he discovered economics.

It opened his mind to a different way to make a meaningful difference to society, not just saving lives in a medical sense but enriching livelihoods in a purposeful and meaningful manner. That sense of purpose has led him to grow from strength to strength in his banking career.

Today, as Group Executive and Group Head of Consumer Banking Group and Wealth Management, this sense of purpose continues to be his North star. He firmly believes banking has a soul, that is, its fundamental purpose is noble, promotes the healthy functioning and development of economies, which in turn improve the lives of people.

In his last role as Country Head of DBS Singapore, he led the bank through the pandemic, helping SMEs, communities and families stay economically resilient with digital, credit and insurance initiatives. He has also helmed key management roles in Standard Chartered previously, including CEO of StanChart Indonesia, Head of Governance (Europe, Middle East, Africa & Americas), Chief Information Officer (Singapore), Head of Technology & Operations (Singapore) and Regional Head of Trade.

In 2021, Tse Koon was conferred the Institute of Banking & Finance (IBF) Distinguished Fellow Award (Corporate Banking). The following year, he received the Medal of Commendation (Star) by the National Trade Union Congress (NTUC) for his leadership in creating a future-ready workforce at DBS.

Currently on the Board of Directors of NETS Pte Ltd and the Chairman of the Association of Banks in Singapore’s (ABS) Culture and Conduct Steering Group, Tse Koon also sits on the Board of Governors for the Singapore International Foundation (SIF) and Nanyang Polytechnic. Tse Koon champions gender diversity and is a mentor with BoardAgender by Singapore Council of Women’s Organisation.

Besides banking, his other great love is swimming. He swears it is the secret to his energetic youthfulness.
