Hedge fund billionaire Chris Rokos is preparing to leave the UK and relocate his residency to Greece, with plans to open an office in Athens, according to reports including Bloomberg. Rokos is the founder of Rokos Capital Management.

Multiple outlets link the move to concerns among some wealthy individuals about potential tax changes. The Independent and Evening Standard both cite Rokos’s large tax payments—reportedly £330 million to the Treasury last year—as context for why his departure is notable. The Evening Standard specifically connects the decision to worries about Labour raising taxes in the October Budget, while other coverage frames it more generally as part of a wider pattern of high-profile exits by the UK’s super-rich.

Overall, the sources agree on the planned move and the reported scale of Rokos’s tax bill, but they differ in emphasis: some stress broader apprehension about future tax policy, while others point more directly to a specific upcoming Budget.
