The Office for Budget Responsibility (OBR), Britain’s independent fiscal watchdog, has increased its estimates for potential taxpayer losses for propping up the banks eight years ago by more than £9bn.
Earlier this year the OBR said that it expects costs of £17.5bn. This means it is the second time in 2016 that the watchdog has recalculated the value of the remaining stakes, as turmoil in financial markets has hammered bank shares.
The Government spent nearly £137bn to save the largest highest banks at the height of the financial crisis – including the Royal Bank of Scotland, Northern Rock and Lloyds Banking Group.
The lenders either failed or were at the brink of collapse between 2007 and 2009.
It has so far recouped just £63bn, less than half the amount spent and the additional interest on the debt used to buy the holdings keeps increasing, threatening a bigger overall loss.
"If all interventions were financed through gilts, the Treasury estimates that additional debt interest costs would have amounted to £29.6bn by end-September, mainly due to the costs associated with RBS and UK Asset Resolution, the company managing the Government's stakes in Northern Rock and Bradford & Bingley," the OBR said.
Additionally, shares in RBS and Lloyds have fallen about fifth since the Brexit vote in June, reducing the value of the Government’s holding.
