JEDDAH, Saudi Arabia — President Joe Biden will urge Saudi Arabia to boost oil production when he visits Jeddah this weekend, but experts do not expect a significant increase given his administration’s frosty ties with the desert kingdom and doubts over spare output capacity.

Raising oil output could help bring down gas prices and ease raging inflation in the U.S. — which at 9.1% in June was the highest in 41 years — ahead of crucial midterm elections in November.

But Biden’s tough line on Saudi Arabia’s human rights record and uncertainty over how much more oil Saudi Arabia can produce have meant prices have remained stubbornly high, a sign markets are not pricing in expectations of extra supply any time soon.

In 2019, while he was campaigning for the presidency, Biden described Saudi Arabia as a “pariah” state over the killing of the journalist Jamal Khashoggi, which the CIA blamed on the country’s de facto ruler, Crown Prince Mohammed bin Salman.

“I think the crown prince is not going to go out of his way for Biden. … The comments that were made during the presidential campaign, these are lasting comments. I don’t know how you reset after those comments,” said Stephen Innes, the managing partner at SPI Asset Management.

The International Energy Agency’s July oil market report says the best bet for spare oil capacity lies with the United Arab Emirates and Saudi Arabia, which between them could boost supply by 2.6 million barrels a day, according to the agency’s data.

That compares with June’s total output of 43.6 million barrels a day pumped by the OPEC oil-producing cartel and allied producing countries, which includes Russia’s contribution of 9.74 million barrels a day.

The U.S. and its allies want to reduce reliance on Russian oil because of Moscow’s war in Ukraine and make up the difference elsewhere.

But last month, French President Emmanuel Macron was caught on camera telling Biden that the UAE’s ruler had confided in him that his country was already pumping as much as it could and that Saudi Arabia could offer only a little more capacity.

“I don’t know who’s playing the bluffing game here, whether they’re playing against the Biden hand because they’re still annoyed at what he said during the elections over the Khashoggi incident,” Innes said.

However, there are doubts over the accuracy of the International Energy Agency data, another oil industry expert said.

“There’s always a certain ambiguity, especially with regards to something like spare capacity, even with regards to production,” said Craig Erlam, a market analyst with OANDA, which provides currency and trading data.
