The economic fallout from the coronavirus could increase global poverty by as much a half a billion.
This bleak warning comes from a United Nations (UN) study into the financial and human cost of the pandemic.
It will be the first time that poverty has increased globally in 30 years, according to the report.
The findings come ahead of key meetings of the World Bank, International Monetary Fund (IMF) and G20 finance ministers next week.
The United Nations University study was written by experts at King’s College London and Australian National University (ANU).
“The economic crisis is potentially going to be even more severe than the health crisis,” said Christopher Hoy from ANU.
The report, which estimates a 400-600 million increase in the number of people in poverty across the globe, says the potential impact of the virus poses a real challenge to the UN Sustainable Development Goal of ending poverty by 2030.
“Our findings point towards the importance of a dramatic expansion of social safety nets in developing countries as soon as possible and – more broadly – much greater attention to the impact of Covid in developing countries and what the international community can do to help,” said Professor Andy Sumner of King’s College London.
By the time the pandemic is over half of the world’s population of 7.8 billion people could be living in poverty. About 40% of the new poor could be concentrated in East Asia and the Pacific, with about one third in both Sub-Saharan Africa and South Asia.
Earlier this week, more than 100 global organisations called for debt payments to be waived this year for developing countries, which would free up $25bn (£20bn) in cash to support their economies.
