Indians pay four times for a litre of petrol compared to its crude price, which is actually only around a litre of packaged drinking water. Taxes, commissions and other charges levied on the end-user ensure that fuel rates do not go down significantly in India even when international crude oil prices are low.

Ideally, retail prices of petrol and diesel in the domestic market are linked to global crude prices. It means if crude prices drop in the international market, then prices in retail should come down too. But this is not the case most of the time, especially in India.
After the gradual easing of the lockdown, crude oil price was revived to Rs 25 a litre in January this year, but consumers ended up paying Rs 87.57 per litre, more than three times higher. This is because every time crude prices fall, the government imposes fresh taxes.
On May 5, 2020, when crude prices halved to Rs 14.75 from Rs 28.84 per litre, the government hiked excise duty by a record Rs10 per litre on petrol and Rs 13 per litre on diesel to garner additional revenue of Rs 1.6 lakh crore. This was the second hike within a period of three months.
The Indian government is trying to revive a crippled economy ( due to many reasons) but sadly yet again the scapegoat is the "common man" 😥
