The United States announced a sweeping sanctions package targeting Russia’s oil trade on Friday (January 10), with 183 tankers—a sizable part of the so-called shadow fleet that has kept Russian oil flowing to major consumers such as India and China—being placed under sanctions.

Indian refiners have stopped dealing with U.S.-sanctioned oil tankers and entities but the country does not expect disruption to Russian crude supplies during a two-month wind-down period, a government source said on Monday.

India’s state refiners are rushing to speed up payments for Russian crude, hoping to complete their trades before a dramatic expansion of Washington’s curbs on Moscow’s oil industry effectively comes into force next month,
