A meeting on Threadneedle Street
Jamie Dimon is meeting John Healey. The boss of America's biggest bank is in London to see Britain's new Chancellor. This is their first meeting. They spoke once on the phone. This time it is face to face on Wednesday, a conversation that will set the tone for the new government’s relationship with the entire financial sector. At stake is a simple question. A hard question. How much tax should banks pay? The answer will determine the flow of billions in investment and the security of thousands of British jobs. One man represents global capital. The other represents a government desperate for cash. It is a fundamental conflict.
The government’s position is clear, if unspoken. It needs money. John Healey, as the new Chancellor, faces immense pressure to fund his party’s promises, and he must present his inaugural budget in October. The Treasury is actively looking for new revenue streams. Deep speculation is swirling around the City that one of those streams will be a higher windfall tax on the banking sector, a one off levy on profits that have been swollen by higher interest rates. This is a politically popular move. It is an easy target. But it comes with a price.
This is why Dimon is here. He is not just any banker. He is the chief executive of JP Morgan and is widely regarded as one of the most influential figures in global finance, a Wall Street billionaire whose opinions can move markets. He is in London to deliver a warning. It is understood he will caution the Chancellor directly that raising taxes on his industry would be a mistake, a move that would actively place investment and employment in the United Kingdom at risk. The message is blunt. Tax us more and we may invest less. We may employ fewer people. That is the threat.
So this is the Chancellor’s first major test. Healey has to weigh the immediate political gain from a popular bank tax against the long term economic risk of alienating a sector that is critical to the British economy. The meeting on Wednesday is not just a polite introduction between two powerful men. It is a negotiation. A high stakes one. The new government wants a reputation for financial stability and fiscal discipline, but it also wants to demonstrate that it can make big corporations pay their share. Dimon’s visit forces the issue into the open. It presents the Chancellor with a choice. One he must make before his October budget.
Who is Jamie Dimon?
Jamie Dimon is the boss of JP Morgan. It is America’s largest bank. This alone makes him a significant figure, but his personal standing transcends his corporate title. He is a Wall Street billionaire. He is also widely seen as one of the most powerful people in global finance. That is not hyperbole. His words can affect markets, influencing investor sentiment across continents with a single public statement. He is the closest thing the financial world has to a spokesman. His leadership through multiple crises has given him a status few others can claim, making him a barometer for the anxieties of the entire banking sector. His views are scrutinised. They are analysed. They are treated by competitors and governments as a direct insight into the thinking of American finance.
JP Morgan’s operations in Britain are substantial. That much is clear from the Chancellor’s diary. John Healey is not meeting a minor player. The threat Dimon carries concerns 'investment and employment in the UK', which means the bank has significant investment and employment to put at risk. This is the source of his leverage. The jobs in question are not theoretical. The investment is not imaginary. While the specific figures are proprietary, the warning implies a vast British enterprise whose future commitment is now being questioned aloud by its most senior executive. The bank is a core part of the City’s complex machinery, a conduit for international capital and a major participant in London’s financial markets. Any decision by JP Morgan to scale back its British presence would create ripples far beyond its own balance sheet. It would be a signal. A damaging one.
Dimon therefore represents more than just one bank. He embodies the entire international financial community that the new government says it wants to keep onside. A meeting with the Chancellor is not an everyday occurrence. The fact that this one is happening, just weeks before a critical budget, shows the weight his visit carries within the Treasury. He is not just lobbying. He is testing the water. He is gauging the temperature of a new administration whose rhetoric on wealth has made investors nervous. The phone call that preceded this face to face meeting was the prelude. This London meeting is the main event. The Chancellor has to decide how to react to a man who personifies the global capital Britain needs, but who also represents the concentration of wealth that the government’s supporters expect it to challenge.
The tax at the heart of the argument
The argument is about tax. Cold, hard tax. The new government needs cash for its programmes and the banking sector, with its colossal profits, is an obvious place to look. Two ideas are at the centre of speculation ahead of the October budget, and Jamie Dimon is in London to argue against both of them. His message is simple. Do not do it.
The first, and perhaps more likely, policy would be an increase to the bank corporation tax surcharge. This is not a new concept. It is an extra levy, applied only to the profits of banks, on top of the standard rate of corporation tax that all large companies in the United Kingdom are required to pay. Its existence is a legacy of the 2008 financial crisis. The government’s logic is that banks pose a unique systemic risk and should therefore contribute more to the exchequer. They should pay extra. Right now, on top of the 25 per cent corporation tax rate, banks pay an additional 3 per cent. A combined rate of 28 per cent. The Treasury could raise that surcharge. A move to 5 per cent, for example, would lift the total tax on bank profits to 30 per cent, a significant jump that would bring billions of pounds into the government’s coffers.
The second, more dramatic option is a windfall tax. This is different. A windfall tax is a one off charge. It is designed to capture profits that are considered excessive or the result of luck rather than skill or investment. The precedent for such a move is recent. The government has already imposed a windfall tax on the profits of oil and gas companies, arguing they benefited unfairly from spiralling global energy prices. The same logic could now be applied to the banking sector. Banks have seen their profits swell as central banks have raised interest rates to combat inflation. This has widened the gap between what they charge for loans and what they pay to savers, a gap which has delivered huge earnings. A windfall tax would seize a portion of that money for the Treasury. It would be temporary. It would also be deeply controversial.
These are not small sums. The financial services sector contributed £75.6 billion in total tax in the last recorded year. It is a vast river of revenue. Even a minor change in the tax rate results in a major change in the final sum. The Chancellor, John Healey, sees this as a potential source of funding for hospitals and schools. Jamie Dimon sees it as capital that JP Morgan could use for other things, money that could be reinvested to grow the business, paid out to shareholders including British pension funds, or held as a buffer against future economic shocks. Dimon’s warning is that this capital is mobile. If it is taxed too heavily in London, it will simply find a new home in New York or in a rival European hub like Paris. The money will leave. The jobs will follow.
The new chancellor's difficult choice
The new Chancellor needs cash. A lot of cash. New governments always make promises. Fulfilling them requires billions of pounds the Treasury does not currently have. John Healey must find the money to fund pledges on everything from hospitals to schools, and he must find it quickly before his first budget in October. To many in his party, the towering profits of the banking sector look like the most obvious place to start. Banks are enjoying a boom. Taking a larger slice seems fair. It seems simple.
His meeting with Jamie Dimon on Wednesday complicates things. It is a reminder that the Chancellor answers to two masters. The first is the British electorate. The second is the global financial market. Dimon is not a voter. He is not a member of parliament. He represents a constituency just as powerful, a global system that watches every move the British government makes and has the power to move trillions of pounds in an instant. The confidence of this system directly affects the value of the pound, the cost of government borrowing, and the health of thousands of British pension funds. This is not an abstract concept. It is cold, hard cash.
So Healey is trapped. A difficult choice awaits. He can listen to the bankers, keep tax rates stable, and hope that continued investment and growth will eventually generate the revenue he needs, a path that risks accusations of being too close to the City and failing to deliver on campaign promises. Or he can impose higher taxes, pleasing his political supporters and securing a short term injection of funds for public services, but gambling with the UK’s long term reputation as a place to do business. The risk is not theoretical. It is a threat to jobs and tax receipts.
This decision is bigger than the bank surcharge. It is about the new government’s identity. The October budget is the first test. The choice Healey makes on bank taxation will be read by everyone from trade union leaders in Liverpool to investment managers in Singapore as a clear signal of the government’s true priorities. It will tell them whether this is an administration that will prioritise wealth redistribution above all else, or one that seeks to build a stable, long term partnership with international finance. He cannot satisfy them both. He must choose.
Is the City's threat real?
The City’s warning is as old as its cobbled lanes. Raise our taxes and we will leave. The threat is always the same. Jobs will go. Investment will dry up. Frankfurt and Paris are mentioned often. But moving a global bank is not a simple exercise. It is not like packing up a shop. It is a monumental undertaking, costing billions of pounds and causing years of expensive, complex disruption for staff, clients, and the institution itself. London possesses advantages built over three hundred years. It has a concentration of expertise, a trusted legal framework, and the English language. These are powerful anchors. They are not easily cut.
Yet the bankers are not bluffing entirely. The threat is not empty. Some jobs have already moved. Since the Brexit vote in 2016, major banks including JP Morgan have shifted staff and assets to offices inside the European Union to ensure they can continue to serve clients within the single market. The drift is slow. It is incremental. But it is real. Paris has aggressively courted financiers with tax breaks. Frankfurt has tried to lure them with its proximity to the European Central Bank. London is no longer the automatic, undisputed choice for every new financial project or every dollar of new investment. It has serious rivals. This competition is a permanent feature of the new reality.
This is the core of Jamie Dimon’s argument to the new chancellor. The danger is not a dramatic exit, with JP Morgan’s Canary Wharf headquarters suddenly emptied and its 22,000 UK staff put on planes to France. The risk is quiet decline. A slow erosion. It is about where the next wave of investment goes. Will a new technology centre be built in London or will it be allocated to Dublin. Will the next generation of traders be hired in the City or in Paris. These are the decisions that a higher tax burden influences, the slow but significant choices made in boardrooms thousands of miles away that determine whether Britain’s largest service industry grows or shrinks. Mr Healey’s choice in the October budget is not just about collecting more tax from banks next year. It is a bet on where the world’s biggest banks will choose to place their money, and their people, for the next ten years.
What to watch in the October budget
The October budget is the test. Chancellor John Healey faces a choice that will set the tone for his relationship with Britain's most powerful industry, a decision between raising immediate cash through a windfall tax or heeding the warnings of bankers like Jamie Dimon. The stakes are high. Two paths diverge. One path involves raising the bank corporation tax surcharge or imposing a fresh windfall levy, a move that would please party activists but send a confrontational signal to international finance.
The other path is caution. Leaving the tax regime untouched would be read in boardrooms from New York to Hong Kong as a sign that Mr Healey has prioritised investment stability over short term revenue gains. It would be a win for Dimon. The banks would be relieved. This would suggest the new government believes the threats of capital flight are credible and that a partnership with the City is essential for delivering long term economic growth. Mr Healey might also try for a third way. He could announce a review, deferring the hard choice while buying himself political time.
The signal matters most. The specific percentage point of any tax increase is less significant than what the decision says about the new government's fundamental approach to wealth, risk and the role of the City in Britain's economy. This is a statement of intent. Whether John Healey chooses confrontation or conciliation in his first budget will be the clearest indicator yet of the government’s economic direction, defining a relationship with global finance that will have consequences for thousands of jobs and billions in investment for the next decade.
