Barclays reported £2.3bn in pre-tax profits for July-September 2024, up 12% year-on-year, and announced a further £500m share buyback — bringing total shareholder returns since January to £2.8bn through buybacks and dividends. The results land days before the chancellor's 28 October budget, where a hike in UK bank taxes is widely expected. The profit engine is straightforward: net interest income at Barclays' UK retail banking arm rose 6% to £2bn. This is the spread between what banks charge borrowers and what they pay depositors. When interest rates rise — as they have, driven partly by inflation expectations linked to the Iran war — that spread widens. Banks did not invent the rate environment, but they are its primary beneficiaries, while mortgage holders absorb the cost. The TUC has been campaigning for months on exactly this point. General secretary Paul Nowak framed it bluntly: Britain's big four banks have made £200bn in profit since 2021, underpinned by what he called "mortgage misery for millions." The union body wants the budget tax increase to redirect some of those gains toward household and business support during an energy bill crunch. Chancellor John Healey's upcoming budget, under Prime Minister Andy Burnham's government, is expected to include a bank tax hike as one of several revenue-raising measures to fund cost-of-living programmes. The scale of the increase remains unknown. What is known is the asymmetry: £2.8bn has already flowed to Barclays shareholders this year alone, setting the baseline against which any tax will be measured. CEO CS Venkatakrishnan's decision to announce the buyback now — days before a budget that could increase the bank's tax burden — is either confidence or signalling. It tells markets the bank can absorb whatever comes. It also tells government that shareholder returns are the priority, and any new tax will come out of a pool that was heading to investors regardless. The structural picture is clear: rising rates transfer wealth from borrowers to lenders. Banks pass most of that to shareholders. Government then tries to claw some back through taxation. Each step involves friction, delay, and political negotiation — during which households continue paying elevated mortgage costs. The TUC's £200bn figure since 2021 is the cumulative scale of what this cycle has already produced. Whether the budget levy is material or symbolic will determine whether this is a policy correction or theatre. A meaningful tax would need to be calibrated against the net interest income windfall itself — not against headline profits — to avoid being absorbed as a rounding error in a £2.8bn shareholder return programme.
