The magnitude of the economic losses will depend on how the outbreak evolves, which remains highly uncertain.
The range of scenarios explored in the analysis suggests a global impact in the range of $77 billion to $347 billion, or 0.1% to 0.4% of global gross domestic product (GDP).
In a moderate scenario, where precautionary behaviors and restrictions such as travel bans start easing 3 months after the outbreak intensified and restrictions were imposed in late January, global losses could reach $156 billion, or 0.2% of global GDP.
The People’s Republic of China (PRC) would account for $103 billion of those losses—or 0.8% of its GDP. The rest of developing Asia would lose $22 billion, or 0.2% of its GDP, it said.
“There are many uncertainties about COVID-19, including its economic impact,” said ADB Chief Economist Yasuyuki Sawada. “This requires the use of multiple scenarios to provide a clearer picture of potential losses. We hope this analysis can support governments as they prepare clear and decisive responses to mitigate the human and economic impacts of this outbreak.”
