Oil Prices Decline as U.S.-Iran Talks in Qatar Remain Uncertain

Oil prices closed out a month marked by significant declines on Tuesday, as energy market participants closely monitored the potential for fresh talks between the U.S. and Iran in Qatar.

International benchmark Brent crude futures with August delivery ticked lower to $72.92 per barrel. The contract dropped roughly 21% in June, its largest monthly decline since March 2020.

U.S. West Texas Intermediate futures with August delivery dropped 1.8% to $69.50 on Tuesday. With Tuesday's decline, the becnhmark dtopped more than 20% in June, its worst monthly performance going back to late 2021.

The moves come as oil traders monitor prospects for U.S.-Iran talks in Doha. Still, both benchmarks are up on the year as the U.S. war with Iran squeezed production and distribution.

U.S. President Donald Trump on Monday said talks between the two countries would take place in Qatar's capital on Tuesday, claiming via social media that Tehran had "requested a meeting" following an exchange of strikes over the weekend.

A spokesperson for Iran's Foreign Ministry on Monday reportedly denied that talks were scheduled over the coming days. They added that an Iranian technical delegation's visit to Qatar this week was not related to U.S. officials visiting the country.

U.S. special envoys Jared Kushner and Steve Witkoff arrived in Doha on Tuesday. A Qatari government spokesperson said they would meet mediators, not directly with the Iranians.

The mixed messaging appears to underscore the fragility of an interim peace deal reached by the U.S. and Iran earlier this month.

The two countries struck a 14-point memorandum of understanding on June 17 to pause fighting that had severely disrupted global oil flows through the strategically vital Strait of Hormuz.

Located in the gulf between Oman and Iran, the Strait of Hormuz is recognized as one of the world's most critical energy choke points. The narrow waterway typically handles around 20% of the world's oil traffic.

Energy analysts say they have been surprised by the pace of the sell-off in the oil market, noting that it has been far more aggressive than most had expected.

"The price action in recent weeks reflects a market that is treating this temporary ceasefire between the US and Iran as a permanent deal. This is clearly not the case, and as we have seen over the last four months, the situation can change very quickly," strategists at ING said in a research note published Monday.

"It took long enough to agree on a temporary ceasefire. Reaching a permanent deal which tackles the nuclear issue within 60 days would be very optimistic. Of course, there is always the potential for the ceasefire to be extended, which would effectively be kicking the can down the road," they added.
