The Bank of England on Tuesday unveiled yet more measures aimed at calming markets rocked by a UK budget as it warned over risks to the nation's financial stability.

The week had already seen action taken by the BoE and UK government aimed at bringing calm to bond markets in particular as state borrowing soars.

The moves are a response to soaring UK bond yields and after the pound tumbled to a record low against the dollar since the government of new Prime Minister Liz Truss unveiled debt-fuelled tax cuts in a budget last month.

A day after it launched a temporary facility aimed at easing liquidity pressures, the central bank Tuesday said it was widening the scope of daily purchases of UK government bonds, or gilts, until Friday.

In a statement, the BoE said the latest action would "act as a further backstop to restore orderly market conditions".

It noted that "the beginning of this week has seen a further significant repricing of UK government debt, particularly index-linked gilts", which the central bank will now purchase under its wider operation of bond purchases.

"Dysfunction in this market, and the prospect of self-reinforcing 'fire sale' dynamics pose a material risk to UK financial stability," it added.

In more positive news, official data Tuesday revealed British unemployment fell to a near 50-year low at 3.5 percent.

Wages, however, continue to be eroded by sky-high inflation.

The British government on Monday brought forward key economic forecasts to Halloween, hoping not to spook markets further.

Finance minister Kwasi Kwarteng will unveil debt-reduction plans and independent economic predictions on October 31 rather than in late November.

It comes after Chancellor of the Exchequer Kwarteng was already forced to axe a tax cut for the richest earners, in the face of outrage as millions of Britons face a cost-of-living crisis with UK inflation around 10 percent.

Britain meanwhile faces "big and painful" cuts in public spending to fix state finances should it decide against more U-turns over tax cuts, a leading think tank warned Tuesday.

"With a weaker economy, getting government finances on a sustainable path without cancelling tax cuts could force... big and painful spending cuts," the Institute for Fiscal Studies said in a study.

Reducing debt "through spending cuts alone, without actually specifying which budgets would be cut, risks stretching credulity to breaking point", it added.

The budget was widely criticised, including by the International Monetary Fund, over fears that government debt would balloon to pay for the tax cuts, including on salaries of all UK workers.

Fitch last week lowered the outlook on its credit rating for British government debt to negative from stable.

The BoE has piled on further pressure by hiking its main interest rate to a 14-year high of 2.25 percent in a bid to cool inflation -- and is expected to go even stronger on tightening next month.

This in turn has seen retail banks ramp up interest rates on mortgages, with analysts predicting heavy price falls for property.
