Billionaire Chris Rokos poised to leave UK

Published: 08 September 2026. The English Chronicle Desk. The English Chronicle Online.

Billionaire hedge fund manager Chris Rokos is preparing to leave the UK and move his tax residency to Greece, according to reports, making him the latest prominent member of Britain’s wealthy financial community to consider relocating amid debate over the country’s tax policies.

Rokos, founder of Rokos Capital Management, is reportedly planning to establish an office in Athens as part of the move. His expected departure comes at a sensitive moment for the UK, where the government is attempting to encourage investment and economic growth while also facing pressure to raise revenue from wealthier individuals.

The possible relocation has drawn attention partly because of Rokos’s unusually large contribution to the UK tax system. He was ranked among the country’s biggest individual taxpayers last year, with an estimated tax bill of £330 million in 2025.

His departure would therefore carry significance beyond the personal decision of one billionaire. It has renewed questions about whether changes to the UK’s tax regime could encourage some high-net-worth individuals to establish residency elsewhere, potentially affecting tax revenues, investment decisions and Britain’s attractiveness as a financial centre.

Rokos founded his hedge fund business in 2015 after a career in financial markets. His wealth is estimated at around $4 billion, placing him among the richest individuals associated with Britain’s investment industry.

Despite his enormous wealth, Rokos has maintained a relatively low public profile. His name attracted wider attention earlier this year when he announced a record £190 million donation to the University of Cambridge to support the creation of the Rokos School of Government.

At the time, Rokos said he wanted to give something back to Britain. His educational background included attending a state primary school before receiving a scholarship to Eton College and later studying mathematics at Oxford University.

The donation was seen as a major contribution to British higher education and reflected Rokos’s longstanding links with the country. His reported decision to move his residency to Greece therefore creates a notable contrast between his philanthropic ties to Britain and his future tax arrangements.

Rokos has also invested heavily in property. Over much of the past decade, he has overseen an extensive renovation of Tottenham House, a large historic mansion near Marlborough in Wiltshire. The project has reportedly involved hundreds of rooms and major additions, including leisure and entertainment facilities.

His potential move comes as Britain continues to debate the consequences of recent changes to taxation for wealthy individuals. The abolition of the long-standing non-domiciled tax regime has been particularly controversial among international investors and wealthy residents with financial interests outside the UK.

The previous system allowed qualifying non-domiciled residents to receive certain tax advantages on foreign income and gains. The Labour government replaced that arrangement with a residence-based framework under which foreign income and gains can become subject to UK taxation after a shorter period.

The new system has also changed the treatment of inheritance tax for long-term residents with substantial international assets. These reforms were introduced as part of a broader effort to make the tax system more consistent and increase revenue from wealthy taxpayers.

Supporters of the changes argue that individuals with substantial financial resources should contribute fairly to public finances. Critics, however, have warned that higher taxes could encourage some wealthy people to move their residency to countries offering more favourable arrangements.

Greece is among the European countries seeking to attract wealthy international residents. Its high-net-worth investor regime allows qualifying individuals to pay a fixed annual tax on foreign income, subject to specific conditions and investment requirements.

Under the Greek system described in reports, eligible applicants can commit at least €500,000 to qualifying investments such as real estate, businesses or shares within a specified period. Those who qualify can then face a flat annual tax of €100,000 on income earned abroad.

For someone with substantial international income, such arrangements can make a significant difference to the overall tax burden. Greece has therefore positioned itself as one of several European destinations competing to attract wealthy individuals who may be reconsidering where they establish tax residency.

Italy has adopted a similar strategy and has become another prominent destination for wealthy foreigners. Its own flat-tax system on foreign-sourced income has helped attract high-net-worth individuals, particularly to financial centres such as Milan.

Rokos’s reported decision follows other high-profile departures from Britain in recent years. Among those who have reportedly changed their residency are prominent figures from international finance and business, including Shravin Bharti Mittal, Nassef Sawiris and Richard Gnodde.

Their individual circumstances differ, and it is difficult to establish how much influence UK tax policy played in every case. Some have moved to other European countries, while others have established residency in the Middle East.

The broader question is whether these departures represent a significant trend or simply a series of individual decisions by people whose wealth and international business interests give them unusual freedom over where they live.

Official figures so far provide a more complicated picture. Provisional data showed that the number of non-domiciled residents in the UK fell by only about 0.5% in the tax year ending in April last year, leaving approximately 73,400 people in that category.

That relatively modest decline suggests that claims of a large-scale exodus of wealthy residents should be treated cautiously. At the same time, official statistics may not immediately capture longer-term changes in investment behaviour, residency decisions or the movement of businesses and assets.

The issue is particularly important for the UK’s financial sector. London has traditionally benefited from its position as a global centre for banking, investment management, private equity and hedge funds. The city’s appeal has been supported by its financial expertise, legal infrastructure, international connections and access to global capital.

Tax policy is only one factor influencing where wealthy individuals choose to live and where financial firms operate. Business opportunities, political stability, access to skilled workers, education, property markets and quality of life can all play a role.

Nevertheless, the possibility of a major taxpayer such as Rokos leaving Britain gives renewed prominence to the debate over how far governments can increase taxes on wealth without discouraging high-value economic activity.

The timing is also notable because Chancellor John Healey is preparing to present his first budget in October. In a major speech, he said he wanted Britain to be seen as a country focused on wealth creation, signalling the importance of encouraging investment and entrepreneurship alongside efforts to raise public revenue.

The political debate surrounding wealth taxation is likely to continue. Prime Minister Andy Burnham has previously supported higher taxation of wealth but later indicated that such measures would not be increased immediately after taking office.

For the government, the challenge is to maintain public confidence in the fairness of the tax system while ensuring that Britain remains attractive to people who create businesses, employ workers and invest capital.

For wealthy individuals, the calculation can be very different. When a person has international investments, substantial income and the ability to establish residency elsewhere, even relatively small differences between national tax systems can influence decisions about where to live.

Rokos’s reported move to Greece therefore represents more than a change of address. It highlights the increasingly international nature of wealth and the competition between countries seeking to attract or retain high-net-worth residents.

His case also carries a personal dimension. A man who has donated hundreds of millions of pounds to a British university and invested heavily in a historic British property may still decide that another country offers a more suitable long-term tax environment.

There is no indication that his reported relocation means he is severing all connections with Britain. His business, philanthropic interests and property holdings may continue to maintain strong links with the country.

For Britain, however, the story raises a difficult economic question. The government wants wealthy individuals to contribute more to public finances, but it also wants the country to remain a leading destination for investment and wealth creation.

Finding that balance will become increasingly important as wealthy individuals gain greater access to international alternatives. Greece, Italy and other countries are actively competing for high-net-worth residents, meaning Britain’s tax decisions are increasingly being made within a global marketplace.

Rokos’s reported departure will therefore be closely watched by policymakers, investors and the wider financial community. Whether it becomes another example of a wealthy Briton seeking a more favourable tax environment or remains an isolated personal decision, it has once again placed the relationship between taxation, wealth and Britain’s economic competitiveness firmly in the spotlight.
