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.


Sim S Lim

If there’s one thing clients agree about Sim, it’s that he’s always candid. He sums up his ethos in just two words: truth and logic. An approach that yields conclusions that are consistently consistent. And one that has served him well for over 35 years, banking across Asia, North America and the Middle East.

Today, Sim is responsible for DBS’ Consumer Banking and Wealth Management business, and was DBS' first country head for 8 years, delivering greater synergy and value across the bank in Singapore.

Before joining DBS, Sim was President and CEO of Nikko Citigroup, where he also oversaw corporate & investment banking, institutional brokerage and fixed income & equity trading in Japan as a board member of Nikko Citi Holdings.

In 2007/2008, he was Citigroup Country Officer, and Chairman of Citibank in Hong Kong, developing the strategy for Hong Kong’s markets and banking franchise, and supporting the consumer and wealth management businesses.

Prior to that, Sim was Regional Head of Emerging Markets Sales and Trading for the Asia-Pacific, based in Singapore. He was responsible for foreign exchange, local currency derivatives & money markets, fixed income trading & origination in 13 markets. During this period, he was also the non-executive Chairman of Citibank in Malaysia.

Presently, Sim is Chairman of DBS Vickers Securities Holdings. He sits on the board of Nikko Asset Management in Japan, as well as the Building and Construction Authority, and ST Engineering. He also serves as Singapore's High Commissioner (Non-Resident) to the Federal Republic of Nigeria.

A Japanese government Monbusho scholar, Sim graduated with his Bachelor's in BA from Yokohama National University, Japan in 1983.


Hou Wey Fook

As the Chief Investment Officer, Hou Wey Fook invests the way he golfs – every shot carefully calculated for risk and reward. It's a discipline he attributes to his training as an engineer, which means listening to the math even if it goes against human nature.

Wey Fook joined DBS in September 2017, and is responsible for investment strategies in DBS, which include global strategic and tactical asset allocations for our clients.

With over 30 years of fund management experience, Wey Fook was most recently at Bank of Singapore where he held various senior management roles, including Chief Investment Officer, and Head of Discretionary Portfolio Management (DPM) and Funds.

Joseph Poon

Managing Director and Group Head of DBS Private Bank, Joseph Poon starts his day at 4am, training for marathons. He sees the parallel between running a race and running the Private Bank business in the consistency and discipline needed for both.

Joseph is also Head of DBS Treasures Private Client in Singapore and Hong Kong, a responsibility he took up to after his role as Region Head of Southeast Asia.

He brings to DBS over 20 years of banking experience, most recently from his role in UBS. As Southeast Asia Head of the Ultra High Net Worth segment and Head of Global Family Office, Southeast Asia, he drove the strategic growth for UBS' highest valued clients by delivering bespoke solutions across the bank's Investment Banking, Asset Management and Wealth Management segments.

As Chief Operating Officer, he most recently led the acquisition and integration of Société Générale private banking business in Singapore and Hong Kong, and ANZ’s wealth and retail banking across 5 countries.

Daryl Wong

Circumstances change. Daryl believes it’s his responsibility and duty to ensure clients understand the situation, and have solutions that work for them in the long run.

Prior to joining DBS, Daryl’s career took him from Singapore to Shanghai, and finally to Hong Kong, in investment advisory and investment product management and sales.

Alex Tan

Alex sees many similarities between golf and wealth management. For instance, knowing when to slow down, to get out of the rough before taking the long shot. While keeping an eye on the prize.

It’s a principle he finds more relevant than ever in a changing world, as Head of Investment Products & Advisory for Hong Kong Wealth Management.

In his role, Alex oversees the Hong Kong Investment Product and Advisory teams and the Hong Kong-based Regional Wealth Chief Investment Office (North Asia).

Alex joined DBS Private Bank as a Fixed Income specialist in 2003, progressing to be the Head of Fixed Income, before becoming the Head of Capital Market Products & Execution in 2016.
