The International Monetary Fund has weighed in on the UK budget debate with a recommendation that lands like a class-sorting algorithm: cut pensions and welfare, leave the banks alone. Helge Berger, deputy director of the IMF's European department, told reporters in Bangkok that with taxes at roughly 40% of GDP — historically high for Britain — the emphasis should fall on the spending side. He specifically named the pensions triple lock and "better targeting" of social benefits as the right places to look, rather than a bank surcharge hike. The backdrop makes the advice remarkable. The UK's four largest lenders — HSBC, NatWest, Barclays, and Lloyds — reported £29.2bn in profits in the first half of the year alone. Nearly half, £13.7bn, was pledged to shareholders through dividends and buybacks. Over five years, those four banks have raked in £200bn in pre-tax profits. Meanwhile, TUC analysis shows the Treasury lost £6bn in revenue over the three years since the Tories cut the bank surcharge from 8% to 3% in 2023. The banks did not pass on the savings as lending — they passed them to shareholders. City lobbyists have run a coordinated pressure campaign. UK Finance chief David Postings wrote to Healey and Burnham on 12 October with commissioned research claiming a surcharge reversal would leave annual GDP £1.2bn lower in real terms by 2029-30 and reduce lending by £10.4bn. Jamie Dimon of JP Morgan threatened to scrap a £3bn London headquarters if the government became "hostile." Banks have pointed to lower overall tax charges in Frankfurt, Dublin, and Amsterdam. Former banker and author Philip Augar called the bluff directly: "They always say this. They rarely move." He noted banks are enjoying "boom conditions" partly from good management but largely from high interest rates — economic conditions not of their own making. He argued a moderate tax increase of £2-3bn annually is well within the sector's capacity. His sharpest line cut to the structural asymmetry: "Banks can't be too big to fail and too big to tax." The IMF's recommendation follows a familiar institutional playbook. When fiscal space tightens, the prescription is always the same: protect capital mobility, discipline labour costs. Berger suggested property taxes or VAT if revenue were truly needed — both regressive instruments that fall hardest on households. At no point did he address the £6bn revenue hole created by the surcharge cut, the £13.7bn flowing to shareholders in a single half-year, or the structural asymmetry of a sector that demands public bailouts in downturns and tax immunity in booms. Labour has already signalled it will reform the triple lock, giving the IMF's framing convenient political cover. But the underlying question is distributional, not technical. The banks' own numbers reveal the answer: £200bn in five-year profits, half of recent earnings sent to investors, and a lobbying apparatus deployed the moment the state hints at clawing back a fraction. The debate is not about whether the UK can afford to tax banks. It's about whether it can afford not to. Healey's budget decision will signal which constituency the government answers to. A surcharge reversal to 8% would raise an estimated £2-3bn annually — roughly what the triple lock costs in a single uprating year. The choice between those two levers is not economic. It is political.
