Mumbai: The BSE benchmark Sensex on Monday slipped nearly 262 points due to panic sell-offs by investors who were caught off guard by massive spike in crude prices after drone attack on the Saudi Arabia's largest oil processing facility.
Tracking oil prices movement, the Indian rupee saw heavy depreciation in value against the US dollar, spooking investors here, experts said.

On the other hand, TechM, ONGC, Sun Pharma, HUL, TCS and Bharti Airtel rose up to 1.44 per cent.
According to experts, equities plunged after global crude oil price skyrocketed over 10 per cent after drones attacked two Saudi Arabian plants on Saturday.
The attack has effectively knocked out over half of Saudi Arabia's production as it cut 5.7 million barrels per day or over 5 per cent of the world's supply.

"Moreover, the Indian economy will also get impacted due to surge in crude oil prices. No wonder, the Indian equity market ignored the important initiatives announced by the government to the support housing sector and boost exports, he added.
