Meanwhile, the benchmark Brent crude oil price stayed flat on Friday despite US dollar sliding for the past couple of days.

The international crude oil prices are one of the several factors that directly affect the fuel prices in India. Since October last year petrol and diesel prices have risen continuously due to the crude oil price rally. While crude oil price rose significantly by $16 a barrel to later fall down by nearly $7 a barrel in the last four months, the petrol and diesel prices rose by Rs 5 and Rs 7 per litre respectively. To cushion the impact of higher crude oil prices, the central government announced an excise duty cut of Rs 2 per litre in October, followed by VAT cut by four states. It was also expected that Finance Minister Arun Jaitley will announce some relief in the Budget 2018, it is understood that tight fiscal situation did not leave the room. The government had earlier indicated that it may announce another excise duty cut, when and if, crude oil prices touched $75 a barrel. The Indian government in 2010 announced deregulation of the fuel prices in India and it is now being revised by the oil companies based on free-market theory. The oil companies used to revise petrol and diesel prices fortnightly, however, since June 16, 2017, daily revision of prices kicked in. Since then, oil companies have revised prices between 1 paisa and 15 paise, which often go unnoticed.
