Single Family Office vs Multi Family Office Singapore
The SFO vs MFO decision is fundamentally about AUM scale and control. Below ~US$50M, an MFO usually wins on cost. Above ~US$100M, the SFO economic and governance case usually wins. The crossover zone in between is where most of the real decisions get made.
Side-by-side
| Criterion | Single Family Office (SFO) | Multi Family Office (MFO) |
|---|---|---|
| Typical AUM band | US$50M+ | US$10M – US$200M per family |
| Cost structure | Fixed (S$1–3M / year) | % of AUM (0.5–1.5% typical) |
| Investment control | Direct (family + RM) | Shared (MFO recommends, family approves) |
| Privacy | High — internal team only | Moderate — shared with MFO |
| MAS licensing | Typically exempt (related-person rule) | Capital Markets Services Licence (FMC) |
| 13O / 13U eligibility | Yes (typical applicant) | Not directly; family vehicles within MFO can apply |
| Setup time | 6–12 months | 4–8 weeks onboarding |
| Talent risk | High — concentrated in your team | Lower — MFO replaces departures |
| Best for | US$100M+ families with strong governance preferences | US$20–100M families wanting institutional-quality access without overhead |
Decision tree
Investable AUM under US$20M
→ Stay with private-banking tier (HSBC Premier Private Client, OCBC Premier Private Client, DBS Treasures Private Client). Family-office structure not economic yet.
US$20M – US$50M
→ MFO with 13O sub-fund structure. Most efficient combination at this band. Private-bank custody + MFO advisory + 13O tax exemption on a family vehicle inside the MFO platform.
US$50M – US$100M
→ The decision band. Either MFO (lower cost, faster setup, lower governance burden) or SFO with 13U (higher cost, more control, deeper substance). Often driven by family preferences on privacy, intergenerational vision, and direct-investment plans.
US$100M – US$500M
→ SFO usually. Cost economics tilt toward dedicated team + 13U + dedicated VCC sub-funds. Governance, privacy, and direct-investment programmes start to matter materially.
US$500M+
→ Mature SFO. Often includes CIO + 8–20 investment professionals + family-governance council + dedicated philanthropy arm. Some families add a public-facing MFO arm to monetise infrastructure (Hong Kong + Switzerland have precedents).
Hybrid pattern: SFO using MFO services
A common middle path is an SFO that outsources specific functions to MFOs or specialist providers — typically alternatives sourcing, philanthropy administration, or next-generation programmes. The SFO retains direct investment control on listed-market mandates and 13O/13U eligibility, while leveraging MFO infrastructure for specialised functions where the SFO would otherwise have to build out internal capability.
Common questions
Why not just stay with private banking?
For most families up to US$25M, a private bank alone is fine. Above US$25M, private banks usually push you toward their family-office desk which is closer in structure to an MFO. Above US$50M, the privacy, control, and tax-efficiency case for a structure begins to outweigh the simplicity of pure private banking. See private banking Singapore for the comparison tier.
Can an SFO use multiple custodian banks?
Yes, and most SFOs above US$100M use two to four custodian relationships to diversify counterparty risk and access different product platforms. Typical pattern: one Asian PB (DBS PB or Bank of Singapore) + one Swiss PB (UBS or Julius Baer) + one US UHNW PB (JP Morgan PB or Citi PB) for alternatives and US-equity coverage.
How many SG-licensed MFOs are there?
Roughly 50–80 firms hold themselves out as multi-family offices in Singapore — though regulatory definitions are loose. Some are Capital Markets Services Licensees, some are Exempt Financial Advisers, some operate via affiliate structures with private banks. See our firms directory for MAS-published licence records.
Does the 13U non-family-member rule apply to MFOs?
The non-family-member rule applies to 13U-eligible SFO structures. Inside an MFO, families typically don't apply for 13U directly — the MFO operates under its own MAS licence and structures family vehicles under 13O where applicable. Pure 13U status requires a dedicated SFO vehicle.
