Countries are increasingly competing to attract wealthy individuals to boost their economies. These mobile wealthy individuals bring investment, entrepreneurship, and long-term growth potential. The Henley Private Wealth Migration Report 2026 ranks countries on their competitiveness for attracting this wealth, evaluating factors like tax policy and business environment. Singapore leads the rankings, recognized for its low taxes, political stability, and business-friendly policies. Many smaller economies, with populations under 10 million, also perform strongly in attracting wealth. These nations often excel by offering predictable regulations, efficient tax systems, and straightforward residency pathways. In contrast, the United States lags due to structural challenges like citizenship-based taxation and fiscal complexity. The U.S.'s taxation of worldwide income, regardless of residency, can also be a deterrent. The global pool of millionaires is growing, with nearly one million new millionaires in 2025 alone. Attracting even a small number of affluent residents can significantly benefit smaller economies through investment and spending.
