Which 2020 market crash followed the global spread of COVID-19 and a collapse in oil demand?

The 2020 market crash followed the global spread of COVID-19 and a collapse in oil demand. It became one of the fastest stock-market declines in modern history.

As governments introduced travel restrictions, business closures, and social-distancing measures, investors feared a severe worldwide recession. An oil-price dispute between Saudi Arabia and Russia intensified the turmoil by contributing to a sharp fall in crude prices. Major equity indexes entered bear-market territory in March 2020.

The decline was followed by an unusually rapid rebound, supported by central-bank action, government stimulus, and expectations of economic recovery. The crash is sometimes grouped with the broader pandemic recession, but the term specifically describes the abrupt market sell-off concentrated in February and March 2020.
