Investment offices for some of the world’s wealthiest families are reducing exposure to US assets and favouring Chinese ones, along with those in other parts of the world, Swiss investment bank UBS has found.While North America continued to make up the biggest share of their portfolios, many planned to diversify in Asia and western Europe, according to insights the bank garnered from 307 family offices in more than 30 markets.Many of those surveyed also planned to increase diversification across currencies “amid a more complex, global investment landscape”, the UBS Global Family Office Report 2026, which was released on Friday, said.The surveyed offices – with an average net worth of US$2.7 billion – were “gradually tilting” towards emerging market equities and infrastructure, the report said, though North America remained a “backbone”.Family offices are privately run firms that manage the investments and financial affairs of an ultra-high-net-worth family or families with an eye towards passing wealth on to younger generations.
