Oil prices rose sharply on Thursday after President Trump announced sanctions on Russia’s two largest oil companies as his frustration with President Vladimir V. Putin over the war in Ukraine mounted.
Brent crude, the international benchmark, rose about 5.5 percent to $66 a barrel. European natural gas prices also rose more than 3 percent as the European Union approved its own package of sanctions on Russia, which include a ban on imports of Russian liquefied natural gas from 2027.
Mr. Trump’s actions threaten to restrict one of the world’s main sources of crude supplies. Russia exports around 4.5 million barrels a day, Mr. Bronze estimated.
