Russia will agree to limit oil prices - U.S. Treasury Secretary Yellen

• "Russia will face a ban on insurance and financial services at the end of the year, which we estimate will result in a loss of 3 to 5 million barrels," she said.

"So why should they retaliate against an initiative that allows their oil to continue to flow to world markets at a favorable price?" added Yellen, explaining her position.

• According to the White House, with Russian oil being abandoned, new consumers will not be able to absorb the full amount of energy produced. In this case, Russia will be forced to sell oil at marginal prices or close the fields.
