Oil prices skyrocketed on Thursday after President Donald Trump told CNBC Saudis and Russia will ease pressure on oil, ending a price war that has contributed to crude's massive plunge.

West Texas Intermediate crude futures surged 24.67% to settle at $25.32 per barrel, for its largest single-day percentage gain in history. Given WTI's 59% decline this year a smaller gain, of course, now accounts for a much larger percentage move. International benchmark Brent crude jumped 17.8%, or $4.40, to trade at $29.14 per barrel.

Trump told CNBC's Joe Kernen Thursday that he spoke to President Putin yesterday and Saudi Crown Prince Thursday and expects them to announce an oil production cut of 10 million barrels and could be up to 15 million.

The president later tweeted that a production cut would be "great for the oil & gas industry!" His comments came before a meeting with energy industry executives scheduled for Friday.

"It will be very welcomed by the industry in the short run," Dallas Fed President Robert Kaplan said on CNBC's "Squawk on the Street." "As long as the coronavirus continues, there's just a substantial amount of excess capacity being generated every day ... It will be particularly helpful as we come out of this virus and will speed the time hopefully where the supply-demand for oil can get back into balance."

Oil production is typically discussed in terms of barrels per day, but Trump made no reference to the time frame of the cuts. Additionally, it was not clear how the cuts would be distributed across oil-producing countries.

RBC commodity strategist Helima Croft said the U.S. could have to give up something in return.

"What we know is the Saudis were looking at this through the lens of the financial crisis and believe they needed a response commensurate to 08/09," she said, referring to the collapse of prices during the 2008-09 financial crisis.

"The question is can Trump put together the package that gets them to do that?" Croft said. "We know there's an emergency OPEC meeting. They will be looking for signs that U.S. production will be curtailed. They will be watching what happens with the Texas Railroad Commission and with Canada," she said.
