EMEA crude futures tumbled by over 5% in after-hours trading on Tuesday as growing optimism that the US and Iran could reach a peace deal eased concerns over Middle East supply disruptions and raised the prospect of additional barrels returning to global markets.
Brent crude futures plunged 5.3% to $79.31 per barrel, while Murban crude futures dropped 5.1% to $76.94/bbl.
Gelber & Associates said that the decline extends this week's losses to about 10% after the US postponed additional military action to allow more time for diplomacy.
On Tuesday, Qatar said mediators were making progress in efforts to end the US-Iran conflict, although Tehran has denied President Trump's assertion that talks are already under way.
Trump said on Monday that discussions with Iran were taking place, while accusing Tehran's leadership of being "duplicitous" as he warned that Washington would not allow the country to develop a nuclear weapon.
Dr. Majed bin Mohammed Al Ansari, spokesperson for Qatar's Ministry of Foreign Affairs, said that mediators were consistently working to create the appropriate conditions for the resumption of direct dialogue, noting that the efforts are expected to yield positive outcomes in the near future.
Fueling bearish sentiment, US Treasury Secretary Scott Bessent reportedly said that the US and Iran could reach a deal on Tuesday or Wednesday to reopen the Strait of Hormuz with freedom of movement for commercial ships.
Bessent said the warring countries are in talks and there is a chance that a deal could be reached to move toward a more normalized position in the six-month conflict.
Trump said on Sunday that he had called off a planned strike on Iran after receiving a request from Tehran and other countries in the Middle East to allow for negotiations to reopen Hormuz.
"We have previously seen again and again that Trump declares a halt to US attacks and "ongoing negotiations" while Iran then fires yet another set of rockets and drones at US military bases, US Middle East allies or ships sailing through the SoH," said Bjarne Schieldrop, chief commodities analyst at SEB Research.
Traffic through the Middle East energy chokepoints remained subdued, with Kpler data showing a combined 39 confirmed crossings in the Hormuz and Bab el-Mandeb on Aug. 2. The US Central Command has redirected 44 commercial vessels, disabled 2, and boarded 2 as of Aug. 3.
On Monday, the United Kingdom Maritime Trade Operations Center said that a cargo ship was struck by an unknown projectile about 20 nautical miles northeast of Al Khasab, Oman.
The maritime security agency said Iran's Islamic Revolutionary Guard Corps attacks have increased, and harassment activity persists, including hailing and UAV overflight.
On the supply front, OPEC+ approved an oil production quota increase of about 188,000 barrels per day from September on Sunday. The Oxford Institute for Energy Studies projected that OPEC+ crude production is now forecast to decline by 4 million barrels per day in 2026, about 500,000 b/d more than previously expected.
