Financial markets remain turbulent as a massive slowdown in economic activity due to the coronavirus takes hold across Europe and the US.
In the US, shares have rebounded almost 6% after steep falls on Monday.
London’s FTSE 100 has also jumped 2.5% after being down more than 1% earlier on Tuesday. Other major European markets are making similar moves.
It comes amid fresh promises of financial aid to helped bolster growth.
President Donald Trump’s administration said it was considering sending checks to Americans so they have cash to spend during the coronavirus crisis.
It has also increased the amount of tax payments that can be deferred, Treasury Secretary Steve Mnuchin said on Tuesday.
Meanwhile, in the UK, Chancellor Rishi Sunak is expected to announce more financial help later for UK firms affected by the outbreak.
The outgoing head of the Office For Budget Responsibility, Robert Chote, has said a temporary spike in borrowing would be sensible.
Speaking to the Treasury Select Committee he said it was better to spend a “little too much” than too little, adding: “When the fire is large enough, you just spray water” (and worry about the clean up after).
Chris Beauchamp, chief market analyst at IG, said: “The government response from around the globe appears to be ramping up once again, as the chancellor prepares to unveil more measures to help support businesses.
“Whatever is announced, the measures will be expensive, but if they can form a credible package, and one co-ordinated with other governments, then markets may try to find a positive, although it may take time.”
On Monday, French President Emmanuel Macron said his government would guarantee €300bn of loans, and pledged that no French company would be allowed to collapse.
Earlier on Tuesday, Asian shares continued to see volatile trading on with markets in Tokyo, Hong Kong and Shanghai swinging between losses and gains.
The turbulence follows one of the worst days in history for US markets. The Dow Jones lost close to 13% and the S&P 500 fell almost 12%, marking the biggest one-day falls for both indexes since “Black Monday” in 1987.
That followed the US Federal Reserve making another emergency rate cut on Sunday, prompting central banks around the world to ease policy in the biggest co-ordinated response since the global financial crisis more than a decade ago.
Some investors now fear that the world’s central banks may have used most of their ammunition to fight the economic impact of the coronavirus outbreak.
In the last month, the Dow Jones Industrial Average has racked up the five biggest one-day points falls in its 135-year history. In March alone the index has also seen its four biggest one-day points gains on record.
Wall Street’s so-called “Fear Gauge” has just topped the levels seen during the financial crisis more than a decade ago. The Chicago Board Options Exchange’s VIX, a measure of stock market volatility, surged by almost 43%, surpassing the level seen in 2008.
