An increasing number of wealthy Americans are establishing family offices. These institutions provide comprehensive services for ultra-high-net-worth individuals, including wealth investment management and personal affairs handling. They are large-scale and operate discreetly, with their influence on Wall Street and the entire U.S. economy continuously rising. According to Deloitte, the current wealth managed by U.S. family offices is approximately $5.5 trillion, a 67% increase compared to five years ago; it is expected to reach $6.9 trillion this year, and surpass $9 trillion by 2030. Deloitte also predicts that in the coming years, the assets managed by family offices will exceed those of hedge fund companies. Deloitte data shows that there are currently over 8,000 single-family offices worldwide, about one-third more than the 6,130 in 2019, and this number is expected to exceed 10,000 by 2030. Major banks and other financial institutions are eager to meet the various needs of family offices, while entrepreneurs and investment managers are competing to share in the enormous wealth held by these wealthy families.
