$160 Billion in Super Rich Wealth Exits the UK

The $160 Billion Flight From Britain

The exodus of the ultra rich from the UK has reached $160 billion in departed wealth over two years, according to figures calculated from the Bloomberg Billionaires Index. For the first time, the number puts a scale on the money leaving Britain. It now surpasses the total wealth of index-tracked billionaires who still call the country home.

Figures: Wealth exit destination

The cause traces back to tax policy. Since Labour came to power in 2024, it abolished the non-domiciled resident system, which had allowed wealthy foreigners to avoid UK tax on overseas wealth for as long as 15 years. It also raised levies on inherited assets and on profits earned by private markets dealmakers. Constant speculation about further measures has deepened the concern.

Half of the departures were finalized in the weeks before the April 2025 reforms took effect, with many relocating to Monaco, Switzerland, and the United Arab Emirates. Most leavers are foreign nationals with relatively recent ties to Britain. The exception drawing attention is hedge fund manager Chris Rokos, a homegrown success and one of the country's largest taxpayers, who moved to Greece. The open question is whether born and bred Britons now follow.

The stakes are concrete. The UK holds the world's fifth-largest population of dollar millionaires at 2.43 million, behind Germany. Yet the top 1% of earners account for about 27% of all income tax revenue. Their exit removes both tax receipts and spending power, and the strain is already visible in London's luxury housing and hospitality markets.

No single destination has emerged as the clear winner, which underlines how few cities can match London's private wealth ecosystem. The government is now weighing measures to reverse the trend, including a possible investor visa granting residency for 5 million pounds.
