A spectre from the 2008 financial crisis is haunting the UK’s public finances, creating a £22 billion annual headache and prompting calls for a new tax on major banks. The issue stems from quantitative easing (QE), an emergency policy that has inadvertently generated huge “windfall” profits for lenders, which a new report from the IPPR thinktank argues should now be reclaimed.
The QE program involved the Bank of England buying £895 billion of bonds, crediting banks with reserves that earn interest. Initially, this was not a problem, but with the Bank’s base rate now at 4%, the interest paid on these reserves has outstripped the returns on the bonds. This costly imbalance is effectively a transfer of wealth from the public purse to bank balance sheets, which the IPPR suggests correcting with a new bank levy.
The mere mention of this proposal was enough to send shockwaves through the City. On Friday, investors reacted immediately, triggering a mass sell-off of banking stocks. The market capitalisation of the UK’s top banks, including NatWest, Lloyds, Barclays, and HSBC, shrank by a staggering £6.4 billion as shareholders priced in the risk of reduced future earnings.
This development has ignited a debate about fiscal fairness versus economic pragmatism. While the government needs to find revenue to fill a £40 billion budget gap, critics of the proposed tax warn of unintended consequences. Financial analysts question whether such a move aligns with a pro-growth agenda, suggesting it could limit the banks’ capacity to lend and thus act as a brake on the wider economy.
