Which 2020 stock-market crash was triggered by the COVID-19 pandemic and became the fastest bear market in history?

The 2020 stock market crash was triggered by the COVID-19 pandemic and became the fastest bear market in history.

Global markets fell rapidly in February and March 2020 as the virus spread internationally, governments imposed lockdowns, and investors assessed the threat to travel, trade, employment, and corporate earnings. The collapse in demand also contributed to a major oil-price shock after negotiations between OPEC and Russia broke down.

The Dow Jones Industrial Average entered a bear market on 11 March 2020, and trading was temporarily halted several times by automatic circuit breakers. On 23 March, the Federal Reserve expanded emergency support, while governments introduced large fiscal programs.

Markets rebounded unusually quickly after the March low, helped by monetary stimulus, government aid, and expectations of vaccines. The crash is distinct from the longer 2008 financial crisis.
