Further, crude oil prices also slumped around 30 per cent on Monday as Organization of Petroleum Exporting Countries (OEPC) failed to agree on an output cut deal, eventually causing Saudi Arabia to cut its prices as it is likely to increase its production. Saudi Arabia's stance has already raised concerns of an all-out price war.

Brent crude futures are currently trading around $34 per barrel.

On Saturday, Saudi Arabia announced massive discounts to its official selling prices for April, and the nation is reportedly preparing to increase its production above the 10 million barrel per day mark, according to reports.

As per analysts, the oil market witnessed the worst price fall on Monday since the 1991 Gulf War.
