THE Bank of England has slashed interest rates to a new historic low of 0.1 per cent and unleashed another £200 billion to boost the economy in its second emergency move in just over a week to combat the coronavirus hit.

The Bank - headed by new governor Andrew Bailey - cut rates from 0.25 per cent to the lowest level on record as it repeated its warning that the economic impact of the Covid-19 outbreak could be "sharp and large".

Members of the Monetary Policy Committee (MPC) voted unanimously at a special meeting to cut rates and to fire up the money printing presses, by increasing its so-called quantitative easing bond-buying programme by £200 billion to £645 billion.

Policymakers have also upped its new Term Funding Scheme support for small firms.

London's FTSE 100 Index rebounded by more that one per cent soon after the decision, having fallen nearly 140 points earlier in the day.

The Bank said: "The spread of Covid-19 and the measures being taken to contain the virus will result in an economic shock that could be sharp and large, but should be temporary."

It added the latest emergency action comes after "evidence relating to the global and domestic economy and financial markets" as stocks plunge at record rates worldwide.

Mr Bailey told reporters that the MPC was minded to act after "very sharp movements in the financial markets" on Wednesday meant the situation was "bordering on disorderly".

The Bank also said conditions in the UK government bond market have "deteriorated", with gilts hitting new lows due to fears over the impact of coronavirus on growth.

Mr Bailey added that the Bank will "still have room to manoeuvre" if the economy worsens due to the pandemic and could look towards "new financial tools" to provide stimulus.

The move comes after the Bank already cut rates from 0.75 per cent to 0.25 per cent last Wednesday in an unscheduled announcement.

Craig Erlam, senior market analyst at Oanda, said the latest measures sees the Bank "throw the kitchen sink at coronavirus".

But he said the rate cut was "largely symbolic", with the reductions so close to zero having little impact in reality on consumer spending power and borrowing costs.

He added it "highlights just how little room the Bank has to manoeuvre on the traditional side".

"Whether that will be enough to reduce lay-offs and stop good businesses going bust, we'll have to wait and see," he said.
