Though the US has allowed India to buy Russian oil, how much cheap oil can New Delhi purchase? After the US waived the sanctions on Russian oil for 30 days and urged India to buy crude from Moscow so that the global prices could be established, the moot questions are: How much crude oil can India purchase from Moscow, and at what prices? How much Russian oil will India buy? If the price of Brent oil goes up, the price of Russian oil will also go up accordingly. The government-controlled oil refiner was also likely to receive about 700,000 barrels of Russian oil loaded on the Spring Fortune.
