The move comes as the bank adds to its senior private banking leadership across its main markets.
Guan will work alongside Rickie Chan, head of private banking for Greater China and North Asia and chief executive of the Hong Kong branch, and Vi Sun Yang, who is due to join on 29 June 2026 as head of private banking for ASEAN.
Lim has worked in private banking for 35 years, covering front-office roles, investment products and wealth advisory.
He joined Bank of Singapore in 2020 and has been a member of its management committee.
The bank said he will oversee its private banking business across the Middle East, South Asia and international markets from Dubai.
Before this appointment, Lim was global head of financial intermediaries, family office and wealth advisory.
The bank said assets under management from the financial intermediaries’ segment more than doubled in the two years since 2024 under his leadership.
It also said revenue from insurance referrals more than doubled during his time in the family office and wealth advisory business.
He led initiatives including the Bank of Singapore Family Office Catalyst, launched in 2025 for ultra-high-net-worth clients looking to formalise their wealth management structure, with the option of later developing into a single-family office.
Lim is also serving as Interim Global Head of Investment Solutions Group.
He joined the bank as global head of products.
Earlier in his career, he spent 25 years at UBS Wealth Management, where his positions included Asia-Pacific head of wealth planning and Singapore head of investment products and services.
Following Lim’s move, Annabelle Chow, head of financial intermediaries, will become the global segment lead for that business.
She will be responsible for its strategy and offering and will report to Yang.
Chow joined Bank of Singapore in 2016 and has worked with Lim on the financial intermediaries business. The bank said the size of the team she leads tripled across Singapore, Hong Kong and Dubai over the past three years.
She also led the rollout of FIM Alternatives Select, a digital platform for alternative investments developed with fintech firm iCapital. The platform is available to the bank’s financial intermediary partners, also referred to as independent asset managers, and gives access to more than 1,600 funds from over 600 asset managers.
Chow has 20 years of experience in private banking.
Her previous roles included Barclays Wealth in Asia, where she helped establish the financial intermediaries desk, and Credit Suisse, where she worked with family offices serving ultra-high-net-worth clients in Hong Kong and later expanded the bank’s presence in the Asia financial intermediaries segment.
