Chris Rokos, one of Britain’s largest taxpayers and a leading figure in the country’s financial sector, is preparing to leave the UK. According to a Bloomberg report, the founder of Rokos Capital Management will move his tax residency to Greece. However, the fund, which manages a $22 billion portfolio, declined to comment on the development.

The move represents a significant success for Greece, Bloomberg reports, as the country has introduced rules allowing certain foreign nationals to pay a flat annual tax of €100,000 ($116,240) on all income generated abroad.

Who is Chris Rokos?

Chris Rokos is regarded as one of the most prominent figures in Europe’s hedge fund industry and one of the most successful macro traders of his generation. The 55-year-old British investor is the founder and Chief Investment Officer of Rokos Capital Management (RCM), one of the world’s largest global macro hedge funds. According to the University of Cambridge, the firm currently manages more than $22 billion, with offices in London, New York, Singapore and Abu Dhabi.

His career in financial markets began after he studied Mathematics at Oxford University’s Pembroke College, graduating with first-class honors in 1992. He initially worked at UBS and later Goldman Sachs, moving from derivatives and market making into proprietary trading. He subsequently joined Credit Suisse, where he worked with Alan Howard. In 2002, he was one of five founding members of Brevan Howard, which went on to become one of Europe’s most powerful hedge funds.

At Brevan Howard, Rokos built his reputation as an exceptionally successful trader in government bonds and interest-rate markets. During his time at the firm, he is estimated to have generated more than $4 billion in profits for the fund, with particularly strong performance during the global financial crisis.

In 2012, he left Brevan Howard. Following a period during which he managed his personal wealth and became involved in a legal dispute over non-compete restrictions with his former employer, he returned to the markets. In 2015, he founded Rokos Capital Management, building a fund focused on major macroeconomic trends across interest rates, foreign exchange, equities, credit markets, emerging markets and commodities.

RCM has delivered particularly strong returns in recent years. According to The Times, the fund returned approximately 31% in 2024 and 21% in 2025, while the company reported £1.2 billion in revenue and nearly £940 million in profit in its most recently published financial year. Rokos himself received approximately £477 million from the profits.

Despite the size of his wealth and influence, Rokos maintains a notably low public profile. Forbes estimates his personal fortune at approximately $2.3 billion in 2026.

His name nevertheless made headlines in 2026 for another reason: he pledged £190 million to the University of Cambridge to establish the new Rokos School of Government. According to Cambridge, it is the largest single donation to a British university in modern times. The move is linked to his long-standing philanthropic activities, particularly in education and equality of opportunity.

Today, Chris Rokos is among a relatively small group of investors whose views on interest rates, currencies and major shifts in the global economy can influence the performance of funds worth billions of dollars. RCM’s investment model remains closely tied to Rokos and his decisions, explaining both his reputation in international markets and the “key-man risk” that some investors associate with the fund.

Why are they leaving the UK?

Rokos is the latest in a series of prominent investors and business leaders to leave the United Kingdom following the abolition of the controversial non-dom tax regime and increases in taxes affecting everything from private equity investments to inheritances and capital gains.

The prominent investor ranked third in the latest annual Sunday Times list of the UK’s highest taxpayers, with a tax bill of £330 million ($447 million).

The development comes as the new Chancellor of the Exchequer, John Healey, prepares to present his first Budget this autumn, amid growing concern in financial markets over the fragile state of the UK’s public finances.

Healey said in his first major speech on Monday that he wants Britain to become “a wealth-creating country.” He pledged to reduce the burden on businesses but stopped short of signaling tax cuts. Andy Burnham, who succeeded Keir Starmer as prime minister in July, has previously expressed support for higher taxes on wealth.

Healey spoke ahead of his first Budget on October 28, which is expected to be a difficult test. A sell-off in global bond markets has wiped out approximately half of the £23.6 billion fiscal buffer that existed against the government’s fiscal rules in March. The deteriorating outlook, driven by the conflict in the Middle East, has revived speculation about tax increases on banks, oil and wealth.

Since its narrow victory in the 2024 general election, the Labour Party has targeted wealth through taxes on non-doms, inheritances involving family farms and businesses, private equity and private-school fees. In its latest Budget, former Chancellor Rachel Reeves introduced a tax on homes valued at more than £2 billion.

With a net worth of approximately $4 billion according to the Bloomberg Billionaires Index, Rokos is among the United Kingdom’s most prominent figures in finance.

Billionaires including Checkout.com founder Guillaume Pousaz and Egypt’s second-richest man, Nassef Sawiris, left the UK after reforms to the non-dom regime were announced by the previous Conservative government in early 2024. The Labour government subsequently introduced broader changes.

Meanwhile, the UK has introduced a new four-year program known as the Foreign Income and Gains regime, which offers 100% exemption from UK tax on income generated overseas.

The British government describes the four-year replacement system as more competitive. However, countries such as Italy and Greece have introduced their own schemes over the past decade to attract wealthy foreigners, offering longer timeframes similar to Britain’s former non-dom regime.

Greece offers a 15-year tax regime for high-net-worth investors. Italy has a similar 15-year system, but following recent increases, it has set the flat tax at €300,000 on foreign-source income.
