In the year since the COVID-19 outbreak was first diagnosed, it has spread to over 200 countries and all U.S. states. The pandemic has negatively affected global economic growth beyond anything experienced in nearly a century. Estimates so far indicate the virus reduced global economic growth to an annualized rate of -4.5% to -6.0% in 2020, with a partial recovery of 2.5% to 5.2% projected for 2021. Global trade is estimated to have fallen by 5.3% in 2020, but is projected to grow by 8.0% in 2021. The full economic impact of the pandemic likely will remain unclear until the negative health...
