Stock market surge creates one million new millionaires

Global personal wealth grew by 10.8% over the year, marking the sharpest increase since 2017 and doubling the growth rates recorded in 2023 and 2024. Despite these gains, the data reveals a deepening divide. While average wealth climbed, median wealth fell across most of the 56 markets tracked by the bank. In the U.S. specifically, median wealth per adult dropped by nearly 20% between 2020 and 2025, even as average wealth rose by 10% when adjusted for inflation.

UBS estimates the global millionaire population now stands at 58 million, collectively holding approximately $250.6 trillion—nearly half of the world's total wealth. UBS economist James Mazeau attributes this disparity to financial market exposure. Because the U.S. stock market climbed roughly 18% in 2025, those with significant investment portfolios or business stakes saw their net worths grow at an accelerated pace compared to the broader population. As Mazeau noted, wealth creation at the highest levels remains tethered to the performance of business assets and investment holdings.
