The International Monetary Fund predicts that the spread of COVID-19 vaccines will power a stronger global economic recovery in 2021, forecasting that the global economy will grow 5.5 percent this year. Al Jazeera reports that the new figure is an upgrade from the 5.2 percent expansion the IMF forecast in October and would mark the fastest year of global growth since the 2010 snapback from the financial crisis. But the body also warned that economies worldwide will need support from their governments to offset the damage from the pandemic and that coronavirus mutations could cloud the outlook.
