What was the nickname of the global stock-market crash on March 9, 2020, when oil prices also plunged?

Black Monday (2020) was the nickname of the global stock-market crash on March 9, 2020, when oil prices also plunged. Major equity indexes fell sharply as investors reacted to the spreading COVID-19 pandemic and a breakdown in cooperation among major oil producers.

Saudi Arabia announced large production cuts in oil prices after talks involving OPEC and Russia failed. The resulting price war compounded fears that the pandemic would damage travel, trade, employment, and corporate earnings. U.S. trading was halted temporarily by circuit breakers after the S&P 500 fell rapidly.

The March 9 session was one of several extreme market days in early 2020. March 12 and March 16 also produced historic declines as governments introduced restrictions and investors reassessed the economic outlook.

The name Black Monday is not unique to 2020; it is also strongly associated with October 19, 1987. The year is therefore essential when identifying this particular crash.
