Britain has suffered the biggest fall in household wealth among high-income economies since the Covid-19 pandemic, according to the UBS Global Wealth Report 2026.

The Swiss bank’s annual report measures household net wealth – the value of assets such as homes, savings, and investments, minus liabilities – across 56 markets representing more than 90% of global wealth.

According to the report, Britain’s average wealth per adult fell by 23.2% between 2020 and 2025 – the steepest decline among the developed economies surveyed. Median wealth per adult dropped to just over £95,500 ($126,500), leaving the typical Briton slightly wealthier than the French but behind Italians and the Dutch.

UBS chief economist Paul Donovan attributed the decline to Britain’s sharp surge in inflation following the pandemic, which was exacerbated by the energy crisis after the escalation of the Ukraine conflict in 2022. He also pointed to weak housing price growth and Britain’s stock market lagging behind the US market.

The findings come as Britain faces an ongoing cost-of-living crisis. Official figures released on Tuesday showed real household disposable income fell in the first quarter of 2026 amid slow economic growth.

The report appears days after Prime Minister Keir Starmer announced his resignation amid mounting political pressure. Although the government pointed to easing inflation and stronger-than-expected GDP growth, critics argue that many households have seen little improvement in living standards, citing persistent cost-of-living pressures, higher taxes, and repeated declines in real household disposable income.

In contrast, Russia ranked second only to South Korea for growth in average wealth per adult, which increased 36.9% in real terms between 2020 and 2025 despite more than four years of Western sanctions, UBS reported.
