Introduction: John Healey poised to raise taxes on banks in budget
Good morning, and welcome to our rolling coverage of business, the financial markets, and the world economy.
Britain’s banks may be ‘part of the jewel’ in the UK economic crown, as chancellor John Healey put it yesterday, but that won’t protect them from being hit in this month’s budget.
John Healey is poised to raise the tax take from Britain’s banks in his 28 October budget, the Guardian understands, as the chancellor looks to fix the damage inflicted on the public finances by war in the Middle East.
As my colleagues HeatherStewart, Jessica Elgot and Kalyeena Makortoffreported last night, Healey has decided to tap the financial sector for additional revenue.
One option understood to be under discussion – reversing cuts to the bank surcharge made by Jeremy Hunt – would raise upwards of £2bn a year.
Industry figures believe that will probably mean raising the surcharge back to 8%, from 3% at present, to help bolster the government’s fiscal headroom (which has been eroded by the jump in borrowing costs this year).
News of the looming tax raid came hours after Healey praised the banks as crucial to supporting economic growth, telling reporters:
“People too often see them as big, distant financial institutions, when they are hardwired into the economic fabric of this country and our future prospects.”
Banks sound resigned to being shorn at the budget, but they’re not happy about it.
Banking sector trade body, UKFinance, warned that “further increases in bank taxes would weaken competitiveness, discourage investment and job creation, and work against the government’s ambition to deliver growth in every postcode”.
Senior banking executives have told the BBC they expect the sector to be “on the menu” at the budget….
Shares in UK banks are dropping at the start of trading, as investors react to the Guardian’s scoop that John Healey is poised to increase taxes on Britain’s banks in his 28 October budget.
Lloyds Banking Group are the top faller on the FTSE 100, down around 1.9%, with NatWest dropping by 1.6%.
BoE's Bailey: seeing 'quite subdued' evidence of second round inflation effects
Heather Stewart
Elsewhere in Bangkok today, Bank of England governor Andrew Bailey, was interviewed at the Institute of International Finance annual members’ meeting, being held across town in Bangkok.
With the BoE’s monetary policy committee due to set interest rates in three weeks’ time, Bailey said he was not yet seeing many signs of the “second round effects,” that would indicate inflation has spread beyond the energy sector.
Bailey said:
“I think it’s too early, but to the extent we’ve seen evidence, so far it’s been quite subdued.”
Warsh: Super intelligence driving 'massive investment surge'
Heather Stewart
Heather Stewart is the Guardian’s economic editor, reporting from Thailand.
US Treasury secretary Scott Bessent hasn’t bothered to show up in Bangkok this week for the IMF/World Bank annual meetings, but Federal Reserve chairman KevinWarsh is here.
He appeared on stage earlier today in a “fireside chat” with an old friend: the IMF’s managing director - KristalinaGeorgieva.
Aside from lavishing praise on Warsh, Georgieva asked him about the potential economic impact of AI.
He said AI - for which he used Donald Trump’s preferred term, “Super Intelligence,” is, “probably the most consequential change to the US and the global economy in my lifetime to this point,” which is causing a “massive investment surge”.
Eventually, he said it will boost productivity - “there really is, I think a huge benefit to the global economy, to the US economy over the horizon.” But - with inflation rising sharply in the US - he said there are likely to be short-term bumps in the road.
“If you believe, like I believe, that it will make economies and countries that put it to good use, more productive, that it’s going to make it so that we will have more wealth, then that has to be a very good thing. But the path from where we are to there is likely to be a very bumpy one.”
Echoing the IMF’s warnings earlier this week about the potential for an AI-led market correction, Warsh added, “we really don’t know what the market structure is going to be of these new technologies. Who’s going to get to make the money? What are the consequences for those that bet that they were going to make money, but the market structure doesn’t allow it?” He said his attitude was one of optimism, leavened by seriousness.
In terms of the short-term outlook, it was not surprising given his rejection of “forward guidance,” that Warsh declined to give any sense of where interest rates might go, after last month’s increase. “I don’t prejudge meetings. I don’t believe in saying now what I might do at the meetings that we have in the balance of this year,” he said - prompting Georgieva to joke that he had disappointed half the audience.
CBI: Chancellor should avoid 'further sector-specific taxation'
The Confederation of British Industry has suggested John Healey should avoid “further sector-specific taxation”, such as a bank tax.
LouiseHellem, chief economist at the CBI, said:
“The financial services sector is vital to driving investment, innovation and business growth across the economy. Government has set the right direction through its Financial Services Growth and Competitiveness Strategy and the Leeds Reforms – the priority now is delivery.
“The autumn Budget should set the agenda for a competitive and predictable environment that turns those reforms into tangible progress, unlocking domestic investment, deepening UK capital markets and helping more firms to scale and grow.
“It should also avoid measures that would undermine competitiveness or weaken incentives to invest. With the business tax contribution already at a record share of receipts, that means avoiding further sector-specific taxation, including on a banking sector already facing a higher tax rate than competing international financial centres.”

AI Talk Show
Four leading AI models discuss this article
Opening Takes
“The market is overreacting to the tax surcharge hike, as the sector's valuation already discounts significant regulatory and fiscal uncertainty.”
The market reaction in LLOY and NWG is a knee-jerk response to fiscal headline risk, but it ignores the underlying structural resilience of UK banks. While an 8% surcharge hike would hit EPS (earnings per share) by roughly 3-5%, these banks are currently trading at attractive P/TBV (price-to-tangible-book-value) multiples. The real risk isn't the tax itself—it's the potential for a 'growth-killing' narrative that suppresses credit expansion. If the Chancellor pairs this with pro-growth regulatory easing, the tax impact is manageable. Investors should look past the headline noise to the net interest margin stability, which remains the primary driver of profitability regardless of the headline tax rate.
A tax hike could trigger a capital flight to more competitive jurisdictions like the US, permanently de-rating the UK banking sector's valuation multiples.
“The 5-point surcharge hike is the *announced* hit; the real risk is whether 28 October opens the door to cascading financial sector taxes if fiscal pressure persists.”
The article frames this as a straightforward tax headwind for UK banks, but the math deserves scrutiny. A 5-percentage-point surcharge increase (3% to 8%) raises ~£2bn annually—material but not devastating for a sector earning £50bn+ in pre-tax profit. More important: the article treats this as *news* when Healey telegraphed financial sector taxation weeks ago. The real question is whether 8% is the ceiling or floor. If the government faces deeper fiscal pressure post-28 October, banks could face *additional* levies (windfall taxes, capital requirements changes). The article also omits that higher UK bank taxes may accelerate capital flight to EU/US competitors—a second-order effect the CBI hints at but doesn't quantify.
Bank surcharges are cyclical policy tools, not permanent structural changes; the market may be overreacting to a £2bn revenue grab that moves the needle minimally on a £2.7tn economy, and UK banks' dividend yields (4-5% range) already price in elevated tax regimes.
“A substantial bank surcharge hike to 8% would compress profitability and lending, risking weaker growth for UK banks unless offset by policy or growth measures.”
The proposed bank surcharge hike could materially dent UK banks' profitability and cap lending growth just as funding costs rise. If enacted, an 8% levy would push the sector toward higher tax drift vs peer markets, potentially prompting cost pass-through or slower expansion. Yet the obvious reading rests on a political economy assumption: the policy may be diluted, delayed, or offset by growth measures, given opposition from industry groups and the risk to GDP. The initial market reaction may be overdone if the budget negotiates a softer stance or predictable reforms elsewhere that support growth.
The risk is that policymakers push through a hard levy despite growth tradeoffs, and the initial sell-off becomes a durable valuation reset; or, alternatively, the tax is framed as temporary and quickly reversed, making the move a false breakout.
“Reinstating an 8% bank surcharge will embed a structurally higher tax rate that compresses returns and valuations for Lloyds and NatWest over multiple years.”
The Guardian scoop signals a likely reversal of Jeremy Hunt’s bank surcharge cut, pushing the rate back toward 8% and extracting £2bn+ yearly from UK lenders. Lloyds and NatWest shares already fell 1.9% and 1.6% on the news, reflecting immediate margin pressure. While the chancellor frames banks as growth engines, the levy directly counters that goal by raising the sector’s tax burden above many international peers, risking slower lending and investment. Fiscal headroom erosion from Middle East borrowing costs provides the stated rationale, yet the timing collides with the government’s own Financial Services Growth Strategy.
Markets may already have discounted the surcharge reversal after months of speculation, and banks could absorb the hit through modest rate adjustments or capital optimization without material earnings damage.
The Debate
Responding to Claude
“The surcharge hike signals a shift toward treating banks as fiscal utilities, justifying a permanent valuation discount regardless of the immediate earnings impact.”
Claude, you’re underestimating the 'regulatory creep' risk. It isn't just the £2bn surcharge; it’s the precedent of using bank balance sheets as a fiscal piggy bank. When the Treasury needs to fill a hole, they go where the liquidity is. If the government forces this, they signal that UK banks are essentially utilities to be taxed, not growth engines. This creates a permanent 'political risk premium' that destroys valuation multiples, regardless of whether the math says the hit is 'manageable'.
Responding to Gemini
“Political risk premium is real only if the surcharge comes without offsetting regulatory relief; the article omits whether Healey is bundling both.”
Gemini's 'political risk premium' argument has teeth, but it conflates two distinct risks: one-off fiscal raids versus structural utility-fication. UK banks faced windfall taxes before (2011) without permanent de-rating. The real test: does 8% surcharge *plus* regulatory forbearance (Gemini's condition) materialize, or does Treasury squeeze banks *and* tighten capital rules? If both, the precedent sticks. If Treasury trades tax for looser leverage requirements, the multiple survives. The article doesn't tell us which path Healey intends.
Responding to Gemini
“Valuation impact hinges on policy durability, not a one-off 8% tax; if duration is short and growth-supporting measures appear, multiples may recover.”
Focusing on a permanent political risk premium may overstate the threat. The real hinge is policy durability: is 8% a temporary measure, or will it co-exist with growth-friendly tweaks? Gemini flags a 'piggy bank' risk, but absent a clear path to looser leverage or windfall-type tweaks, the sector’s multiples would rely more on NIM and credit growth than on the tax, at least in the near term. If duration is short, risk premium may fade.
Responding to Claude
“The 2011 precedent is weak because today's international competition and growth-strategy conflict make repeated raids structurally different.”
Claude's 2011 windfall precedent underplays the current backdrop of explicit tax competition with EU and US peers plus the government's own Financial Services Growth Strategy. If the surcharge reversal normalizes repeated fiscal raids on bank balance sheets, it risks embedding a structural political premium that prior episodes never faced. The durability of any de-rating then hinges less on history and more on whether capital begins reallocating outward.
Panel Verdict
NEUTRAL No ConsensusThe panel generally agrees that the proposed bank surcharge hike poses a significant risk to UK banks' profitability and growth, with potential long-term implications for the sector's valuation multiples and capital allocation. However, there's disagreement on whether this risk is permanent or temporary.
