Ms Chow joined the Bank in 2016 and has been instrumental in building up its FIMs business with Mr Lim. In line with strong business growth in the last three years, the size of the FIMs team led by Ms Chow tripled across Singapore, Hong Kong and Dubai.
Ms Chow has also spearheaded innovative solutions including alternative investment digital platform FIM Alternatives Select, which was a collaboration with leading global fintech iCapital. The platform, which is availed to the Bank’s FIM partners also known as Independent Asset Managers, provides access to over 1,600 funds from over 600 asset managers.
Ms Chow has 20 years of private banking experience, including stops aHong Kong andlth in Asia where she was instrumental in setting up the FIMs desk, and Credit Suisse AG where she covered family offices of UHNW clients in Hong Kong, and eventually built up the team to expand Credit Suisse’s presence in the Asia FIMs segment.
Testament to Mr Lim and Ms Chow’s success in leading the business, Bank of Singapore was recognised as Best Private Bank for intermediaries by wealth management publications Asian Private Banker and Citywire Asia in 2025.
Mr Jason Moo, Chief Executive Officer of Bank of Singapore, said, “LG is a seasoned private banker with a proven track record and is one of our most experienced management committee members. Appointing him to lead the Dubai team underscores its importance as a key hub alongside Singapore and Hong Kong.
“Together with Rickie and Vi Sun, LG has a strong mandate to drive our UHNW strategy which is a critical component for the Bank’s next phase of growth. Adopting this market-led model for our UHNW strategy will help us to quickly and decisively grow this business. I have every confidence in their ability to capture opportunities in their respective markets. The FIM business also continues to be in good hands, led by Annabelle. Her experience and acumen position her well to grow the business which, alongside the UHNW segment, is a key driver for the Bank.”
