In a repeat of the plunge at the turn of the year, global crude oil prices again fell to the psychological $50 mark, from over $100 last year, this time in the wake of the Iran nuclear deal last month.
The basket of 12 crude oils of the Organisation of Petroleum Exporting Countries (OPEC) closed at $50.50 a barrel of nearly 160 litres on the previous trading day on Friday.
The Indian basket of crude oil fell on Friday to $52.98 a barrel.
The International Energy Agency has said that Iran has at least 17 million barrels of crude oil stored and ready to be shipped.
This would add to the output from OPEC whose production levels are already at a three-year high, at a time when the market remains over-supplied.
Saudi Arabia reported a record crude oil production of 10.6 million barrels per day (bpd) in June, an increase of ore than 200,000 bpd on the previous month.
