BERKELEY HEIGHTS, N.J. — President Trump said Saturday that he had received assurances from King Salman of Saudi Arabia that the kingdom will increase oil production, “maybe up to 2 million barrels” in response to turmoil in Iran and Venezuela. Saudi Arabia acknowledged the call took place, but mentioned no targets.

Trump wrote on Twitter that he had asked the king in a phone call to boost oil production “to make up the difference…Prices to (sic) high! He has agreed!”

An hour later, the state-run Saudi Press Agency reported on the call, but offered few details.

“During the call, the two leaders stressed the need to make efforts to maintain the stability of oil markets and the growth of the global economy,” the statement said.

It added that there also was an understanding that oil-producing countries would need “to compensate for any potential shortage of supplies.” It did not elaborate.

Oil prices have edged higher as the Trump administration has pushed allies to end all purchases of oil from Iran following the U.S. pulling out of the nuclear deal between Tehran and world powers. Prices also have risen with ongoing unrest in Venezuela and fighting in Libya over control of that country’s oil infrastructure.

Last week, members of the Organization of the Petroleum Exporting Countries cartel led by Saudi Arabia and non-cartel members agreed to pump 1 million barrels more crude oil per day, a move that should help contain the recent rise in global energy prices. However, summer months in the U.S. usually lead to increased demand for oil, pushing up the price of gasoline in a midterm election year. A gallon of regular gasoline sold on average in the U.S. for $2.85, up from $2.23 a gallon last year, according to AAA.

If Trump’s comments are accurate, oil analyst Phil Flynn said it could immediately knock $2 or $3 off a barrel of oil

Other analysts were more doubtful about immediate effects.
