Biden will tap oil reserve, hoping to push gasoline prices down.

Energy experts said the reserve release would pack more punch if other countries, like China, also sold oil from their stockpiles. The International Energy Agency, an organization of more than 30 countries, will meet Friday and may recommend further releases from national reserves.

Russian oil exports normally represent more than one of every 10 barrels the world consumes. The United States, Britain and Canada have stopped importing Russian oil, and many oil companies and shippers in Europe have voluntarily stopped buying Russia’s energy products. That has produced a deficit so far of about three million barrels a day.

The average price of regular gasoline in the United States is $4.23 a gallon, according to AAA, the motor club. That’s about the same as it was a week ago but up 62 cents a gallon in the last month.

Oil prices had dropped this week after peace talks between Russia and Ukraine showed the first signs of progress. Energy traders are also concerned that demand could fall as China, the world’s largest oil importer, imposes lockdowns in Shanghai and other places to deal with coronavirus outbreaks.

“The price effect is likely to be short term,” David Goldwyn, who was a senior State Department official in the Obama administration, said about Mr. Biden’s announcement. “But part of the benefit of this release is that it will provide a bridge to when new physical supply comes online in the second half of this year from the U.S., Canada, Brazil and other countries.”

Some environmentalists criticized the reserve release. “Putting more oil on the market is not the solution to our problem but the perpetuation of our problem,” said Mark Brownstein, a senior vice president at the Environmental Defense Fund.

But Meghan L. O’Sullivan, director of the Geopolitics of Energy Project at Harvard’s Kennedy School, said releasing reserves to ease shortages would not imperil the transition to clean energy. “What the last month has told us is that if there is no energy security today, the appetite for taking hard steps on the path of transition will evaporate,” she said.
