Singapore is becoming a second wealth centre for global families. APX examines Bank of Singapore’s US$5m+ private-banking and family-office model.
Executive Summary
Bank of Singapore is one of Asia’s pure-play private-banking names and a useful case study in how Singapore is positioning itself as a global wealth centre. Headquartered in Singapore and backed by OCBC, the bank serves wealthy families across Asia and internationally, with a footprint that includes Hong Kong, Dubai and London.
Its published investment-services material says its services are dedicated to clients with at least US$5 million in investable assets. The bank also has family-office advisory, trust, succession and alternative-investment capabilities. In 2026 it strengthened its Family Office and Wealth Advisory leadership and continued to target ultra-high-net-worth growth, reflecting the broader migration of family-office activity toward Singapore.
Key Takeaways
- Bank of Singapore is a Singapore-headquartered private bank backed by OCBC.
- Its investment-services page states that services are dedicated to clients with at least US$5 million in investable assets.
- Family-office services include structuring, succession planning, trust services, investment management and alternatives.
- Singapore’s attraction combines political and legal stability, regional access, investment infrastructure and a fast-growing family-office ecosystem.
- The key UHNW question is whether Singapore should be the family’s primary booking centre, one of several custody jurisdictions, or simply a source of Asian investment access.
Why Singapore Has Become Hard to Ignore
Singapore offers a combination that appeals to internationally mobile wealth: strong institutions, deep capital markets, a sophisticated legal environment and proximity to Asian growth. The city-state has also built specific structures around family offices and fund management, making it easier for wealthy families to establish professional investment vehicles when the relevant conditions are met.
Bank of Singapore’s Family Office Catalyst, launched in 2025, is one example of how the market is evolving. The solution is designed for UHNW clients seeking some of the advantages associated with a Singapore family-office structure without necessarily building a full standalone office.
Banking, Advice and Trust Under One Roof
Bank of Singapore’s family-office offering combines investment advice with succession and trust services through BOS Trustee. It also provides discretionary and advisory portfolio management and access to alternatives. That integrated architecture can be attractive to families that want fewer counterparties.
As always, concentration needs managing. A family using one institution for banking, custody, investments and trust services should still understand legal separation, counterparty exposure and the independence of each decision-making layer.
Asia as a Second Wealth Centre
For European or Middle Eastern families, Singapore does not have to replace London, Switzerland or Dubai. It can serve as a second liquidity and custody centre, a base for Asian portfolios, or a family-office jurisdiction for the next generation. That is particularly relevant for families whose businesses or heirs are increasingly Asia-facing.
The practical due-diligence questions include booking location, custody entity, deposit protection, lending availability, trust jurisdiction, access to private markets, foreign-exchange execution and how the bank handles cross-border tax reporting.
APX Perspective
Bank of Singapore demonstrates why private banking is becoming geographically plural. UHNW families no longer need one “home” bank for every function. A Singapore relationship can sit alongside European and US institutions, adding geographic diversification and direct Asian market access. The value comes from architecture, not prestige: the family should decide exactly which risks and functions it wants Singapore to carry.
