CNBC reports that Gita Gopinath, chief economist at the International Monetary Fund, said that global economic activity, which has been hit by the coronavirus pandemic, may not fully recover even by the end of 2021.

"We have a recovery projected for 2021 of 5.8% growth, but that is a partial recovery," she told CNBC.

"So even by the end of 2021, we're expecting level of economic activity to be below what we had projected before the virus," she added.

The fast-spreading coronavirus, which has infected more than 2 million people globally, has led authorities to shut schools and businesses - bringing much of the world's economic activity to a halt.

Governments and central banks around the world have stepped in with measures to help businesses and households to survive the crisis - a response that Gopinath said has been "aggressive" and "rapid."

"I think if you compare that to the global financial crisis ... the response has been just that much speedier and the scale of it has been that much bigger," she said, noting that economies around the world have announced about $8 trillion worth of fiscal stimulus.

But she also said that the amount of stimulus is not "equally distributed" across economies, with around $7 trillion coming from G-20 countries.
