What event caused the 2020 global stock-market crash as countries imposed lockdowns?
Answer
COVID-19 pandemic
The event that caused the 2020 global stock-market crash as countries imposed lockdowns was the COVID-19 pandemic.
As the new coronavirus spread internationally in early 2020, governments restricted travel, closed businesses, and imposed lockdowns to slow transmission. Investors rapidly reassessed corporate earnings, employment, energy demand, and supply chains, producing severe selling across global markets.
The crash included an unusually fast bear market. The S&P 500 reached a record close on February 19, 2020, then fell into bear-market territory in March. Several U.S. trading sessions triggered circuit breakers, which temporarily halted trading after large declines.
Central-bank support, government stimulus, and improving expectations about vaccines helped markets rebound. The stock-market crash was part of a broader pandemic shock, not a repeat of the mortgage-driven 2008 Global Financial Crisis.
