JPMorgan (NYSE: JPM) CEO Jamie Dimon Warns UK Against Bank Tax Hikes Ahead of October Budget

JPMorgan (NYSE: JPM) CEO Jamie Dimon has warned the UK against raising taxes on banks ahead of the government’s October 28, 2026 Budget. In a recent call with Chancellor John Healey, Dimon argued that higher bank taxes could push financial jobs and capital overseas. His warning comes as UK banks face growing pressure for higher levies after strong profits. The debate could test London’s appeal as a global financial centre. 

Jamie Dimon Warns UK Against Higher Bank Taxes

JPMorgan (NYSE: JPM) CEO Jamie Dimon has warned UK Chancellor John Healey that higher taxes on banks could push financial jobs and investment overseas. Dimon raised the issue during a recent phone call, ahead of the UK government’s October Budget. He pointed to New York as an example of how tax pressure can affect financial-sector jobs.

Dimon’s comments add pressure to an already heated debate. UK banks face calls for a higher tax burden because of their strong profits. The TUC says the four major banks made £13.8 billion in the first quarter of 2026. They made £45.7 billion in 2025.

Why are UK Banks Facing Calls for Higher Taxes?

The debate centres on whether banks should pay more towards household support and public spending.

The current UK bank surcharge adds 3% to corporation tax on qualifying banking profits above £100 million. The surcharge fell from 8% to 3% in April 2023.

The TUC now wants the government to increase the surcharge. It argues that banks can absorb a higher tax bill after years of strong earnings.

Barclays provides a recent example. Its second-quarter 2026 pre-tax profit reached £3.3 billion, up 31% year on year. Its first-half profit reached £6.1 billion.

How Much Could a Higher Bank Tax Raise?

The TUC has proposed a much higher surcharge and estimates that changes could raise billions of pounds over four years. It has suggested using the revenue to reduce household energy costs.

This creates a clear policy trade-off. Higher taxes could raise more revenue now. However, banks argue that the UK must remain competitive with other major financial centres.

What Does Jamie Dimon’s Warning Mean for JPMorgan?

Dimon’s warning matters because JPMorgan has a major London operation and plans a new headquarters in Canary Wharf. The project is expected to cost around £3 billion.

The CEO has previously warned that tax policy could affect investment decisions. His latest comments therefore put London’s competitiveness back in focus.

However, investors should separate Dimon’s policy warning from JPMorgan’s overall stock outlook. A UK tax increase would affect only part of the bank’s global operations. JPMorgan also earns revenue across consumer banking, investment banking, markets and asset management.

JPMorgan Stock Outlook: What Does Meyka Say?

Meyka’s latest available JPMorgan data shows JPM at around $325.22, with a market capitalisation of about $871.6 billion and a P/E ratio near 15.4. Meyka gives JPM a B+ AI Score and lists AI-based price forecasts of $337.83 for one month, $345.64 for three months and $336.19 for one year.

Meyka’s AI stock analysis tool therefore points to moderate upside from that quoted price. The figures should not be treated as guaranteed targets because market prices and model forecasts can change quickly.

What are Other Analysts Forecasting for JPM?

Analysts also remain broadly constructive after JPMorgan’s second-quarter results. JPMorgan reported adjusted Q2 earnings of $6.14 per share, above the $5.79 consensus estimate. Managed revenue reached $58.02 billion. The bank also raised its 2026 net interest income outlook to about $105.5 billion.

Following the results, KBW raised its target to $384, Barclays lifted its target to $420, Truist moved to $352, and Wells Fargo raised its target to $375.

Could Higher UK Bank Taxes Hurt London?

The central risk is not simply a higher tax bill. It is the possible effect on investment, hiring and capital allocation.

Dimon argues that financial jobs can move when tax costs rise. The TUC takes the opposite view. It says strong bank profits create room for higher taxation without damaging the sector.

The October Budget will therefore matter beyond UK banks. It could signal how the government balances tax revenue with London’s position as a global financial centre.

Conclusion: JPMorgan Bank Tax Warning Puts London’s Competitiveness in Focus

Jamie Dimon’s warning has brought the UK bank-tax debate into sharper focus ahead of the October Budget. Banks are reporting strong profits, giving campaigners a reason to demand higher taxes. Yet JPMorgan’s concerns highlight the risk of weaker investment and job creation. For investors, the key issue is whether the government can raise revenue without reducing London’s long-term appeal to global financial institutions.
