Which 2020 market crash followed the World Health Organization's declaration of COVID-19 as a pandemic?

The 2020 market crash that followed the World Health Organization’s pandemic declaration was the COVID-19 market crash.

Financial markets fell sharply in February and March 2020 as COVID-19 spread internationally, governments imposed restrictions, and investors assessed the threat to travel, employment, supply chains, and corporate earnings. The WHO characterized COVID-19 as a pandemic on March 11, 2020.

The Dow Jones Industrial Average entered a bear market on March 11, and major U.S. indexes experienced several trading halts known as circuit breakers. On March 16, the Dow fell 2,997.10 points, or 12.93 percent, its largest point and percentage drop up to that date.

Markets rebounded rapidly after unprecedented fiscal and monetary support, vaccine development, and changing expectations about reopening. The crash is distinct from the 2020 oil-price collapse, although the two shocks overlapped during the same period.
