Why MFOs Often Make More Sense
Singapore and Hong Kong have become global family office hubs, but many of their single-family offices operate at asset levels that would be considered sub-scale in North America. This structural gap has clear implications for cost efficiency, governance, talent access, and long-term resilience — and increasingly strengthens the case for multi-family office and hybrid models.
North American surveys put the average SFO at US$1.0–1.5 billion, with many in the multi-billion range. Benchmarks often cite US$150–250 million as the minimum efficient scale for a fully built SFO once investment, operations, technology, and governance requirements are factored in.
By contrast, Asia-Pacific analysis suggests an SFO typically needs at least US$100 million, with cost ratios rising sharply below that point. In Singapore and Hong Kong, market data, incentive frameworks, and practitioner experience all indicate that many SFOs cluster in the US$100–250 million range, with a meaningful number below US$100 million.
This scale difference shows up directly in cost. Larger SFOs may contain operating costs to 1–3% of AUM, while smaller ones often face 4–6% before external manager fees. MFOs — spreading fixed costs across multiple families — typically charge 0.5–1.0% for comparable services. The result is that many sub-scale SFOs in Singapore and Hong Kong pay two to five times the percentage cost of an MFO or co-sourced solution.
Talent and governance constraints further amplify this. Asia’s pool of experienced CIOs, COOs, risk leads, and governance professionals is thinner and more competitive than North America’s. Smaller SFOs often struggle to attract and retain senior investment talent, face key-person dependence, and lack segregation of duties across risk and operations. By contrast, MFOs can sustain deeper specialist teams and invest in institutional-grade governance, technology, and cybersecurity.
Regulatory expectations in both Singapore and Hong Kong are also rising — all of which weigh most heavily on small SFOs. Shared MFO platforms can absorb these requirements far more efficiently.
Against this backdrop, the old “control vs outsourcing” narrative is incomplete. While control and privacy remain key reasons Asian families choose SFOs, recent surveys show growing adoption of hybrid models, i.e. lean “SFO-lite” structures, that retain strategic control, family governance, and sensitive decision-making, while outsourcing investment management, operations, reporting, risk, and cybersecurity to MFOs.
For families in the US$100–500 million bracket a hybrid model may deliver the best combination of control, capability, cost efficiency, and resilience.
Fully standalone SFOs remain compelling for genuinely large, complex families, but for many others, an MFO/hybrid model may be a rational default.
