U.S. Treasury says oil price cap 'institutionalizing' Russian crude discounts

NEW YORK (Reuters) - The European Union's agreed $60 per-barrel price cap on Russian seaborne crude oil will keep global markets well supplied while "institutionalizing" discounts created by the threat of such a limit, a senior U.S. Treasury official said on Friday.

The official, speaking to reporters hours after EU governments persuaded holdout Poland to accept the cap, said the move will limit Moscow's oil revenues and divert billions of dollars away from its war in Ukraine.

"By setting the price at $60 per barrel, we're institutionalizing the steep discount at which Putin has been forced to sell Russian oil, a discount that exists in part because the threat of the price cap has forced Russia to offer bargain deals to importing countries," the official said.

In a separate statement, U.S. Treasury Secretary Janet Yellen said the price cap would further constrain Russian President Vladimir Putin's revenues.

"With Russia’s economy already contracting and its budget increasingly stretched thin, the price cap will immediately cut into Putin’s most important source of revenue," Yellen said.
