Which 2020 market crash was triggered by the COVID-19 pandemic and an oil-price dispute?

The market crash triggered by the COVID-19 pandemic and an oil-price dispute was the 2020 stock market crash.

Global share prices fell sharply in February and March 2020 as governments introduced travel restrictions, lockdowns, and other measures to slow the spread of COVID-19. Economic activity and corporate earnings expectations weakened rapidly.

An additional shock came on March 6, when Russia and Saudi Arabia failed to agree on production cuts through OPEC+. Saudi Arabia then increased production and cut prices, while oil demand was falling. The S&P 500 entered a bear market on March 12, and U.S. markets experienced four circuit-breaker halts in March. The crash was followed by an unusually fast rebound supported by fiscal stimulus and central-bank intervention.
