BSE Sensex plunged as much as 769.41 points while NSE Nifty fell 234.45 points on Friday, marking their biggest single-day drop in almost two years, as blue chips including HDFC Bank were hit across the board on fears US stimulus tapering would hit foreign selling.
The market mayhem drained investor wealth by as much as Rs 2 lakh crore.
After gaining 703 points in the last four sessions, BSE Sensex plunged 769.41 points, or 3.97 per cent, to 18,598.18 on all-round selling. Consumer durables, realty, banks and metal sector took major beating.
Dipen Shah, Head of Private Client Group Research, Kotak Securities said: "Markets started on a soft note on weak global cues but fell suddenly and sharply on continuing concerns over the depreciating rupee and tapering of monetary stimulus by US Fed.
Rupee fell to an intra-day low of 62 to the US dollar.
