Jamie Dimon, the longstanding boss of Wall Street lender JP Morgan, has met with key UK political figures, including Chancellor John Healey and Andy Burnham, amidst growing concerns about potential new windfall taxes on banks. These meetings come just weeks before Mr Healey is set to deliver his first Budget on October 28.
Mr Dimon’s discussions in London, which included the Prime Minister and Chancellor after a phone call with Mr Healey last month, highlight the banking sector’s anxiety over proposals to increase levies. The Chancellor is reportedly under pressure to find billions of pounds to repair public finances, particularly following the fallout from the Iran war, as reported by The Telegraph.
Jamie Dimon Warns on UK Bank Tax
The American banker has previously issued strong warnings against the idea of fresh windfall taxes targeting lenders in the UK. Mr Dimon stated that such measures would have “adverse consequences” and represent “one more negative” for the UK’s financial environment. He emphasised JP Morgan’s role as a “great citizen” in the UK, highlighting its employment of people, veterans, and its commitment to growth and training in the country.
During an earlier interview, Mr Dimon cautioned that if a government decided to implement such taxes, it would “over time cause decisions made that they may not like.” He also noted his strong support for Mr Healey’s predecessor, Rachel Reeves, who had resisted calls for increased bank taxes, describing financial services as the “crown jewel in the UK economy” and encouraging regulators to relax City rules.
According to The Telegraph, Andy Burnham joined a meeting between Mr Dimon and Varun Chandra, the Prime Minister’s chief business adviser, a detail also noted by the Financial Times.
Wider Calls for Bank Levies and Industry Concerns
Beyond Mr Dimon’s warnings, there have been increasing calls from various groups for higher taxation on banks. Paul Nowak, the general secretary of the Trades Union Congress (TUC), has argued that reversing the previous Conservative government’s cut to the bank surcharge could raise £9bn over four years, which could then be used to fund cuts to energy bills.
The Green Party has also advocated for a 38% windfall tax on banks, proposing that the revenue could be used to fund tax cuts for small businesses. Furthermore, the Chancellor has been urged to specifically target £4bn in banks’ tax-sheltered profits, according to The Times.
The banking industry itself has voiced concerns. Jane Fraser, CEO of Citi, another major Wall Street bank, warned last month that any increase in taxes risks making the UK a prohibitively expensive place to do business. She highlighted that “money moves with its feet,” and that tax environments in “even Frankfurt and Paris are lower” for banks.
Chancellor’s Stance Ahead of Budget
Chancellor John Healey has stated that a central priority for his first Budget will be “doubling down” on “more growth generated in more places.” While he has refused to rule out raising taxes, he has pledged to “balance the books” and “control public spending.” The looming Budget on October 28 is expected to clarify the government’s approach to public finances and the banking sector.
