The leading centres
The map of cross-border wealth is shifting. In May 2026, BCG placed Hong Kong ahead of Switzerland as the world's largest cross-border wealth centre for the first time, a marker of Asia's rise. Switzerland remains formidable, its private banks holding about CHF 3.4 trillion in assets in 2024 according to KPMG and its asset-management industry about CHF 3.73 trillion by 2025, and it keeps the deepest private-banking bench in Europe. Singapore, meanwhile, reached close to 2,000 single family offices by the end of 2024, cementing its role as Asia's family-office hub, while the UAE centres have grown fastest of all from a smaller base.

Different measures for different aspects of cross-border wealth; not comparable to one another. BCG's ranking marks the first time Switzerland sat second.
Transparency
Cross-border wealth now moves in a transparent environment. More than 120 jurisdictions have committed to the OECD Common Reporting Standard, with about 112 to 113 reportable for the 2025 to 2026 period, and the standard moved to version 2.0 from January 2026, with crypto assets following under the CARF framework in 2027 to 2028. Banking secrecy as a cross-border selling point has effectively ended; what centres now compete on is legal certainty, talent, tax treatment and service depth.
How to read these
These figures measure different things, a ranking of centres, a stock of private-bank assets, a count of offices, a number of reporting jurisdictions, and are not comparable to one another. Read each as a signal within its own lane. Rankings in particular depend on methodology, so BCG's placing of Hong Kong first and Switzerland second is one authoritative reading rather than a settled fact across all sources.
Every figure carries its source and year, marked as a survey result, estimate or projection, for precise citation.
