These potential plans come shortly after Healey described banks as "part of the jewel in the British economic crown" and "hardwired into the economic fabric of this country" at an IMF summit. However, he also broadly acknowledged that "decisions to take in the Budget," leaving the sector with mixed messages.

Industry heavyweights have voiced strong opposition, with one City figure calling a bank tax a "retrograde step" that would not align with the Chancellor's recent positive remarks. Concerns have been raised that such a tax would harm the international competitiveness of the UK's financial services, which already face higher tax burdens than in competing financial centers like Amsterdam, Frankfurt, Dublin, and New York.

One potential lever for Healey could be reversing the reduction of the banking surcharge from eight percent to three percent, a move that could raise an estimated £2 billion annually. However, industry bodies like UK Finance have urged the government to maintain tax stability and focus on reforms that enhance the sector's capacity to finance the wider economy, warning that increased taxes would act as a "tax on investment."
