Chancellor John Healey Poised to Hit Banks With Tax Rise in Budget

By Olivia Hart

Chancellor John Healey is poised to raise taxes on Britain's banks in his first budget on 28 October, the Guardian understands, as the government scrambles to offset damage to the public finances from the war in the Middle East.

The move would mark the first concrete revenue decision of Healey's chancellorship, and it lands squarely on one of the country's most profitable sectors. According to the Guardian's reporting, the plan is directly tied to the fiscal cost of the Iran conflict, which the government believes has blown a hole in the public accounts.

What do we actually know?

Very little is confirmed. The Guardian attributes the story to its own understanding of Treasury thinking, not to an on-the-record statement. Neither Healey nor the Treasury has publicly detailed the size of the tax rise, the mechanism — whether through the bank levy, the surcharge on profits, or another instrument — or the expected yield.

That gap matters. "Poised" is not policy, and budget negotiations routinely leak competing options as ministers jockey before the fiscal event. Until 28 October, every figure circulating about the bank tax remains unconfirmed.

The backdrop is a chancellor under pressure. Healey is in Bangkok, where the International Monetary Fund has been reviewing the UK's books. The fund praised Britain's progress towards balancing the budget and urged him to "stay the course" — a signal that the IMF sees consolidation as unfinished business, not a completed task.

Why banks?

Banking is an obvious target for a chancellor short of revenue. The sector has historically absorbed targeted levies with limited political fallout, and a war-driven fiscal hole gives Healey a ready justification.

But the reporting stops short of answering the questions markets will ask first:

• How much revenue does the Treasury expect to raise?
• Which tax instrument will carry the increase?
• Will the rise be permanent or framed as temporary, war-linked relief?

None of these details appears in the initial report. The absence of a number is itself telling — it suggests the policy may still be under negotiation inside the Treasury.

What does the IMF's endorsement signal?

The fund's applause in Bangkok cuts both ways. Praising "progress towards balancing the books" implies the job is not done; urging the chancellor to "stay the course" reads as an institutional nudge against loosening spending or borrowing.

If Healey follows that advice, the bank tax becomes the path of least resistance: raise revenue without touching income tax or borrowing. The caveat is that IMF praise has preceded U-turns before, and a one-line endorsement in Bangkok binds no one in Whitehall.

Takeaway: the IMF wants fiscal discipline maintained, and a bank levy is the cheapest way for Healey to show it.

What comes next?

The budget lands on 28 October. Between now and then, expect the Treasury to neither confirm nor deny the Guardian's report, the standard choreography ahead of fiscal statements.

Bank shares may wobble on the headline, but without a figure attached, analysts cannot yet price the hit to sector earnings. The real test is whether Healey names a number on the day — and whether the rise covers the war's fiscal damage or merely gestures at it.

Takeaway: a leaked intent is not a budget measure; the 28 October statement will settle whether banks face a real increase or a negotiating trial balloon.
