Stock markets have gone back into reverse after a short-lived boost provided by governments’ plans to cushion the blow of the coronavirus crisis faded.

The FTSE 100 plunged by nearly 4.5% in early trading on Wednesday, wiping out strong gains seen the day before – despite unprecedented measures announced by chancellor Rishi Sunak to help businesses and households weather the storm.

Markets had been lifted on Tuesday by the promise of stimulus measures, with New York’s Dow Jones climbing more than 5% after President Donald Trump unveiled plans for an $850bn stimulus package, including help for airlines.

But it took less than 24 hours for the enthusiasm to fade and Asian markets fell again overnight.

Shanghai was down 0.2%, the Nikkei 225 in Tokyo shed 1.1% and Hong Kong’s Hang Seng was down 1.5%.

Analysts from London Capital Group said that the magnitude of the pandemic is outweighing stimulus hopes.

As far as short-term investors’ psychology, you know that no government policy can stop the fallout from the coronavirus so you’re not ready to buy, but if the blow can be cushioned a little you’re not in quite such a panic to sell.

In response to Mr Sunak’s announcement on Tuesday, they said: We just have our doubts about whether any government can execute complicated measures in time when the support is needed as soon as possible.

S&P Global economists were more pessimistic, writing in a note that the global recession is here and now.

In Europe, Italy’s MIB was down 1%, the French CAC 40 down almost 2.5% and Germany’s DAX down 3.2% on Wednesday morning.

In the oil market, Brent crude has tumbled below $30 a barrel though it inched slightly higher in early trading.

  • Supermarkets were among the stocks gaining on Wednesday morning on news of the chancellor’s holiday on business rates. Sainsbury’s and Marks and Spencer were both up by more than 11% and Tesco by 3%. Ocado and Morrisons climbed by 6% each
  • Airlines continue to suffer – British Airways owner IAG is down 4.2%, Ryanair by 5.3% and easyJet by almost 8%. Aerospace and defence supplier Meggitt fell by more than 21%
  • Leisure-related stocks declined, after the government advised people to avoid large gatherings and many sporting events were cancelled, with JD Sports down almost 10%

COVID-19, the illness caused by the coronavirus, has infected almost 200,000 people worldwide, killing almost 8,000. Most of the cases have been in China – where the virus originated but where it is now almost under control – as well as Italy, Iran and Spain.
