The Cayman Islands remained one of the world’s leading international wealth centres in 2025 as cross-border wealth continued to expand globally.
Boston Consulting Group’s (BCG) Global Wealth Report 2026 ranked Cayman ninth globally, with about US$500 billion in cross-border wealth booked in the jurisdiction during the year.
The consultancy projected Cayman’s cross-border wealth market would expand to around $700 billion by 2030, representing average annual growth of about 6%.
Globally, cross-border wealth rose 8.4% to $15.7 trillion in 2025, according to the report.
BCG said high-net-worth individuals increasingly shifted assets into international financial centres as they sought geographic diversification and politically stable jurisdictions.
The report found that the world’s top 10 booking centres attracted nearly 90% of new cross-border wealth flows during the year and accounted for more than 80% of existing cross-border assets.
Hong Kong overtook Switzerland for the first time to become the world’s largest cross-border booking centre.
Singapore, the United States and the United Kingdom also remained among the dominant global hubs for international wealth flows.
Cayman was grouped alongside other offshore and international financial centres including the Channel Islands, Isle of Man, Luxembourg and the Bahamas.
BCG said wealth creation and offshore wealth booking are becoming increasingly concentrated in jurisdictions with established capital markets, political stability and international financial connectivity.
The report also pointed to growing geopolitical fragmentation in the global wealth market.
According to BCG, two major wealth networks are emerging globally.
One is centred on Hong Kong and Singapore and primarily serves Asian capital flows, while the other is anchored by Switzerland, the US and the UK and serves European, Middle Eastern and Latin American wealth.
The consultancy said financial centres able to connect with both networks could gain long-term structural advantages as global wealth flows continue to evolve.
BCG projected global financial wealth would grow at a compound annual rate of 7% through 2030, assuming geopolitical tensions and energy disruptions ease during the second half of 2026.
Boston Consulting Group publishes the Global Wealth Report annually as part of its research into international wealth management and cross-border financial markets.
