Taxing the banks: what Europe’s windfall levies brought in as Burnham eyes his next move

UK Chancellor John Healey may impose a windfall tax on banks and oil companies in the October budget. The UK's top four lenders (HSBC, NatWest, Barclays, Lloyds) reported £200bn in pre-tax profits over five years. Campaigners argue the tax could fund cost-of-living support. Similar taxes in Spain, Lithuania, Czechia, and Italy raised mixed results, with some facing legal challenges and reduced effectiveness.
