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.
