A long shadow was cast over the upcoming autumn budget on Friday, as fears of a new bank tax came to dominate the financial landscape, wiping £6.4 billion off the sector’s value. A proposal from the IPPR thinktank has suddenly made a windfall levy a central point of speculation, creating a climate of intense uncertainty.
The IPPR’s paper argued that a new tax on banks is justified to recoup the £22 billion annual public cost of the quantitative easing (QE) policy. Given the government’s need to fill a £40 billion fiscal hole, this proposal has moved from the realm of academic debate to a perceived, plausible budget measure.
The market’s reaction was to price in this new uncertainty immediately. The share prices of all major UK lenders fell, with NatWest leading the decline. This shows that investors are now viewing the autumn budget not just through the lens of broad economic policy, but with a specific fear of a targeted, punitive action against their industry.
This shadow is unlikely to lift until the chancellor, Rachel Reeves, provides explicit clarity on her intentions. Until then, the banking sector is likely to remain under pressure, as the fear of a budget-day ambush weighs heavily on investor sentiment and, by extension, on share prices.
