For decades, Switzerland was the undisputed king of offshore wealth. That era just ended, by a razor-thin margin.
Hong Kong’s cross-border wealth has hit $2.95 trillion, according to the Boston Consulting Group’s Global Wealth Report 2026. Switzerland sits at $2.94 trillion. The gap is just $10 billion.
What’s driving the shift
The short answer: mainland China. Capital flowing south from the mainland into Hong Kong’s financial system has been the primary engine behind the city’s ascent.
In 2025, Hong Kong’s cross-border wealth grew 10.7%, reaching $2.9 trillion before climbing further into 2026. A booming IPO market and strong equity performance amplified the effect of those Chinese inflows.
Global cross-border wealth rose 8.4% overall, totaling $15.7 trillion. Hong Kong outpaced that global average by a comfortable margin. Switzerland is projected to expand at roughly 6% annually through 2030. Hong Kong and Singapore are expected to clock about 9% per year over the same period.
The digital asset angle
By mid-2025, 22 banks in Hong Kong had received authorization to distribute digital asset products.
Over 70% of family offices in Hong Kong had invested in or were actively considering digital assets as of late 2025.
What this means for investors
For the digital asset market specifically, Hong Kong’s rise as a wealth hub creates a potentially massive demand channel. When $2.95 trillion in cross-border wealth sits in a jurisdiction where banks can distribute crypto products and family offices are actively allocating to the space, the downstream effects on liquidity are significant.
Singapore, which BCG groups alongside Hong Kong in its 9% growth projection, has been running its own playbook to attract wealth and crypto activity.
Hong Kong’s financial system is deeply intertwined with mainland China’s economy and regulatory preferences. Beijing’s attitude toward capital outflows, crypto, and Hong Kong’s autonomy as a financial center could shift. Investors who remember China’s 2021 crypto crackdown know that policy winds can change fast.
