India is now staring at the possibility of an oil shock after the U.S. decided to implement sweeping sanctions on Russia’s oil industry.

A fresh wave of U.S. sanctions against Russia’s oil industry threatened to disrupt global supplies, sending crude prices to their highest in more than four months.

The Biden administration has imposed some of its toughest sanctions yet on Russia, in a move designed to hit Moscow's energy revenue that is fuelling its war in Ukraine. The measures target more than 200 entities and individuals ranging from traders and officials to insurance companies, as well as hundreds of oil tankers.

Indian Oil Corp (IOC) is seeking high-sulphur oil from the spot market in its first sour crude import tender since March 2022, expecting the latest U.S. sanctions to hit supplies from Moscow, trade sources said on Thursday.

It is India's first tender for sour crude imports since March 2022. IOC and other Indian refiners have significantly increased purchases of Russian oil over the past two years, taking advantage of discounted prices after the West imposed sanctions on Moscow over its full-scale invasion of Ukraine in 2022.
