TOKYO, Feb 28 (Reuters) - World share markets were headed for the worst week since the depths of the 2008 financial crisis as investors ditched risky assets on fears the coronavirus would become a pandemic and trigger a global recession.
Hopes that the epidemic that started in China would be over in a few months and economic activity would return to normal have been shattered, as new infections reported around the world now surpass those in China. worsening global threat from the virus prompted investors to rapidly step up bets the U.S. Federal Reserve would need to cut interest rates as soon as next month to support economic growth. don't even need to wait for economic data to see how badly the economy is being hit. You can tell that the sales of airlines and hotels are already falling by a half or something like that," said Tomoaki Shishido, senior economist at Nomura Securities.
"It is fair to say the impact of the coronavirus will be clearly much bigger than the U.S.-China trade war. So the Fed does not have a reason to take a wait-and-see stance next month," he said.
MSCI all country world index .MIWD00000PUS fell 0.5% after 3.3% drop on Thursday. So far this week it has lost 9.3%, on course for its biggest weekly decline since a 9.8% plunge in November 2008.

In Asia, MSCI's regional index excluding Japan .MIAPJ0000PUS shed 2.4%. Japan's Nikkei .N225 slumped 4.0% on rising fears the Olympics planned in July-August may be called off due to the coronavirus.
"The coronavirus now looks like a pandemic. Markets can cope even if there is big risk as long as we can see the end of the tunnel," said Norihiro Fujito, chief investment strategist at Mitsubishi UFJ Morgan Stanley (NYSE:MS) Securities. "But at the moment, no one can tell how long this will last and how severe it will get."
WHO Director General Tedros Adhanom Ghebreyesus said the virus could become a pandemic as the outbreak spreads to major developed economies such as Germany and France.
About 10 countries reported their first virus cases in the past 24 hours, including Nigeria, the biggest economy in Africa.
