In May, Indian refiners imported 4.7 million barrels, or about nine times more than April and the most of any month based on US government data going back to 2015. If Beijing does impose tariffs on American oil, it could put downward pressure on the price of West Texas Intermediate crude

NEW DELHI: American oil producers may find a new friend in India as they brace for a trade war with China that could curb US shipments.

Refiners in China were the top buyers of American crude oil in May, and have been regular importers since the US revived domestic output and exports in recent years. But sales may slow amid a growing trade war between Beijing and the Trump Administration.

“If China imposes tariffs, their refineries won’t buy US crude since it would cost more,” Sandy Fielden, director of research for commodities and energy at Morningstar Inc., said by telephone. “US sellers would have to find alternative buyers.”

One option could be more shipments to India, which already has been buying more US crude. In May, Indian refiners imported 4.7 million barrels, or about nine times more than April and the most of any month based on US government data going back to 2015.

If Beijing does impose tariffs on American oil, it could put downward pressure on the price of West Texas Intermediate crude, the US benchmark, and may weaken its spread to Brent oil, the global market standard. That could lure India to take more US crude, Fielden said.

To be sure, most Indian refineries are designed to process heavy, high-sulphur Iranian crude, which has been sanctioned. The bulk of the growth in American supply has been in light, low-sulphur oil produced in shale developments.

“Shale crude is not an alternative to Iranian crude,” Fielden said. “Indian refiners can’t absorb all the US oil that was going to China. They can import more, but can they process it?”
