JP Morgan lashes out at ‘unprincipled’ bank tax
JP Morgan criticized the UK's temporary doubling of the bank surcharge to 6% for 15 months, estimating an additional £100m-£150m tax burden. The bank argues the tax singles out the industry, which operates in a competitive global market. Barclays, Lloyds, and NatWest shares rose 3-4% on the smaller-than-feared increase. The OBR estimates the tax will generate £1.5bn but may drive £190m in profits abroad.
How this was made

The 30-second read
Why it matters
The higher tax rate adds £1.5bn to Treasury receipts but may drive banking activity and investment out of the UK.
Market read
The policy creates a regulatory headwind for UK‑based banks while offering a short‑term fiscal boost, influencing both domestic and international banking stocks.
What to watch
Potential lobbying efforts or future policy reversals could mitigate the long‑term impact on UK banks.
Background
The UK government announced a temporary increase in the bank profits surcharge from 3% to 6% for 15 months, aiming to fund energy‑bill relief.
Ticker impact
JP Morgan faces an extra £100m‑£150m tax due to the UK’s temporary bank surcharge increase.
likely downside as market prices in the additional tax expense
The surcharge is a new, time‑limited levy that directly raises JPM's cost base.
Barclays shares rose 3.2% after the surcharge was confirmed lower than feared, but the bank remains exposed to the tax.
moderate pressure after initial bounce fades
Barclays benefits from the smaller-than‑expected surcharge but still faces a higher tax rate.
HSBC is noted as less exposed to the UK bank tax because much of its earnings are overseas.
little to no change in share price
The bank’s earnings are largely generated outside the UK, reducing tax sensitivity.
Market effects
UK banking sector faces higher tax costs, potentially compressing margins across peers.
UK equity indices may see modest pressure; global banks with UK exposure could see varied reactions.
The policy highlights regulatory risk for multinational banks operating in high‑tax jurisdictions.
Counterpoint
If the surcharge is temporary, investors may view the tax as a short‑term hit and price in a rebound once it expires.
