This case study is a piece of industry research built entirely on public data: how Hong Kong grew from a regional financial centre into the world’s largest cross-border wealth hub within a generation. Every figure is verifiable.
Results
| Metric | Figure | Source |
|---|---|---|
| Cross-border wealth | About US$2.5 trillion | BCG Global Wealth Report 2026 |
| SFO count | 3,380+ (end-2025) | InvestHK / Deloitte |
| Growth | 9% a year 2025–2030, first globally | BCG |
| Global media coverage | 600+ reports | BCG |
| CIES threshold | HK$30m (2025) | Policy Address |
Driver 1: sustained policy support
Successive Policy Addresses prioritise family offices: InvestHK’s dedicated FamilyOfficeHK team attracts them, and the 2025 Address cut the CIES residential threshold from HK$50m to HK$30m, lowering the institutional cost of relocation.
Driver 2: the unique Greater Bay Area link
Hong Kong is the only international centre combining mainland capital access with common law — China’s wealth market of RMB 179.33 trillion (Sina Finance, 2026) routes much of its cross-border activity through Hong Kong.
Driver 3: professional-services density
Private banks, lawyers, tax advisers and family office service providers cluster in Hong Kong, giving a one-stop landing experience; a new office can be fully operational in 3–6 months.
What it means for Chinese families
Hong Kong is not the only option — Singapore’s 13O/13U attracts SEA families — but for mainland-facing families its combined connectivity is unmatched. See our comparison guide for dual-hub designs (Compare & Join guides).

Methodology and sources
Every figure in this study comes from a verifiable public source: the BCG Global Wealth Report 2026 for wealth volumes and rankings, InvestHK and Deloitte for family office counts, and the Policy Address for incentive thresholds. Where estimates differ across sources, the study quotes the most conservative figure and names its publisher. No proprietary or anonymous data is used — readers can reproduce every number.
What other jurisdictions can learn
Three lessons transfer beyond Hong Kong. First, policy continuity beats one-off incentives — a decade of consistent messaging outperforms sporadic concessions. Second, professional-services density is self-reinforcing: every new adviser makes the jurisdiction stickier for the next family. Third, a single gateway role — Hong Kong’s bridge to the mainland — is worth more than broad regional ambitions. Jurisdictions that compete only on tax rates miss two of these three drivers.
What families should do next
For families weighing a move, the practical sequence is: confirm the jurisdiction fits the business footprint (see the Hong Kong vs Singapore comparison), complete the Schedule 16E safe harbour assessment in Hong Kong, and then plan residency through CIES. The Institute’s membership guide connects families with the right advisers at each step.
Risks and counterpoints
A balanced case study must state the risks. Hong Kong’s dominance depends on continued mainland connectivity, and geopolitical shocks could disrupt that bridge faster than any policy can repair it. Regional competition is real: Singapore’s incentive framework matures every year, and new entrants compete on cost. Talent costs and office rents in Hong Kong remain among the region’s highest, which squeezes mid-sized family offices that the headline statistics celebrate.
The counterpoint to these risks is momentum: 9% projected annual growth in cross-border wealth (BCG, 2026) is a rising tide that outweighs most frictions for globally active families. The practical conclusion is not “Hong Kong wins forever” but “Hong Kong is the default first hub for mainland-facing families until their footprint says otherwise”.
