India's BSE Sensex fell 8.18% on March 12, 2020, during the COVID-19 stock-market crash.
The decline occurred as investors worldwide reacted to the rapid spread of COVID-19, travel restrictions, economic shutdowns, and uncertainty about corporate earnings. On the same day, the Sensex lost 2,919.26 points, one of its largest absolute falls up to that time. Trading interruptions and emergency policy responses became common in several markets.
The 2020 crash was unusually rapid, but it was followed by a powerful rebound after central banks cut interest rates, governments introduced fiscal support, and vaccines were developed. The crash is distinct from the 2020 oil-price shock, although the two shocks overlapped. Dates and percentages differ among indexes, so a question must identify the Sensex and the exact session.
