Global personal wealth surged 10.8% last year as nearly one million people joined the ranks of millionaires, according to research published by UBS's wealth management division. The Swiss bank attributed the gains to buoyant financial markets.
The findings, released Tuesday, underscore the accelerating concentration of wealth even as households across Europe face persistent inflation and stagnant wages. While asset owners reaped double-digit returns, millions of workers saw their purchasing power erode.
Financial Markets Drive Gains
UBS's research indicates that stock market rallies and rising asset valuations drove the wealth increase in 2025. The report did not specify how wealth gains were distributed geographically or by income bracket, but previous editions have shown that the majority of global wealth growth accrues to the top decile of earners.
The one million new millionaires represent a continuation of trends documented over the past decade, during which ultra-low interest rates and quantitative easing programmes inflated asset prices while wage growth lagged productivity gains in most developed economies.
The Inequality Context
The UBS figures arrive amid renewed debate over wealth taxation in Europe. Several EU member states have proposed or implemented higher levies on capital gains, inheritance, and financial transactions in response to public pressure for more equitable tax systems.
Trade unions and progressive economists have argued that wealth accumulation at the top reflects policy choices—low capital taxation, weak labour protections, and deregulated financial markets—rather than inevitable economic forces. They've called for coordinated EU action to close tax loopholes and fund public services through progressive taxation.
The European Commission has not proposed EU-wide wealth taxes, citing member state sovereignty over direct taxation. However, the bloc has advanced measures targeting corporate tax avoidance and is negotiating a global minimum tax under OECD auspices.
What Comes Next
The wealth surge documented by UBS contrasts sharply with the economic experience of ordinary Europeans. Inflation remains above the European Central Bank's 2% target in several member states, and housing costs have risen faster than incomes in major cities. Food bank usage has increased across the continent.
Whether financial markets can sustain the gains that drove 2025's wealth growth remains uncertain. Rising geopolitical tensions, climate-related economic disruptions, and potential shifts in monetary policy could alter the trajectory.
Why This Matters:
The creation of one million new millionaires in a single year highlights how wealth generated by financial markets flows overwhelmingly to those who already hold substantial assets. For Europe's social democracies, this poses a fundamental challenge: how to maintain social cohesion and fund robust public services when wealth concentrates at the top while wage earners struggle with inflation. The UBS findings don't just document inequality—they underscore the urgency of tax reform, stronger labour protections, and public investment to ensure economic growth benefits the many, not just the few. Without policy intervention, the gap between asset owners and workers will continue to widen, straining the social contract that underpins European democracies.
