Brent crude fell to $79.09-79.22/bbl (-5.4 to -5.6%) and WTI to $75.55-75.95/bbl (-5.5 to -6.0%) by midday Tuesday, both clearing the 5%/24h threshold this desk tracks for a confirmed oil alert. Brent traded below $80 for the first time since mid-July. The prior print was Brent $84.52-84.72, WTI $80.78 (Aug 4 morning).

The driver: Treasury Secretary Scott Bessent told CNBC there is "a chance we may have a deal today or tomorrow" to open the Strait of Hormuz, ruling out an Iranian toll. Secretary of State Rubio said "progress made" but "no final agreement yet." Iran's government spokesman Baghaei has repeatedly denied it: "We are not currently holding negotiations with the United States. Our talks are with Oman."

Nothing physical changed. The Strait of Hormuz remains blockaded; naval enforcement holds at 35 vessels redirected, 2 disabled, 2 boarded. No transit data supports Bessent's claim that ships are "coming out even now." This is the third time in nine days a deal claim from the Trump administration has produced a 5%+ drop (see July 27, August 3); both prior moves partially reversed once transit data failed to confirm improvement. Watch tomorrow's Asia open, and Saudi confirmation or denial of a new Houthi claim to have struck Najran Airport.
