A significant decline in investor wealth occurred as markets experienced heavy selling. The combined market capitalisation of companies fell, representing a substantial erosion of value. This decline resulted in a loss of nearly ₹7.69 lakh crore by noon.

Rising crude oil prices and weak global markets contributed to the downturn. Foreign investor selling also played a role in the market sentiment.
