Brent crude fell to $83.44/bbl (-5.1%) and WTI to $79.57/bbl (~-6%) at the Monday Asia open, both clearing the 5%/24h threshold this desk tracks for a confirmed oil alert. The prior close was Brent $88.18, WTI $84.67 (Aug 2 afternoon).

The driver: President Trump said he "called off" a planned large-scale strike on Iran's energy infrastructure at the request of Qatar, Saudi Arabia, UAE, and Iran itself, and claimed "the perimeters of a deal has been agreed to" for the "Immediate, Complete, and Total OPENING" of the Strait of Hormuz.

Iran disputes the framing. Government spokesman Baghaei said Monday Tehran has "no immediate plan for negotiations with the US" and that the strait will not return to its pre-war status "under no circumstances." Foreign Minister Araghchi separately described Iran-Oman talks as "nearing completion," but on a managed corridor, not the full reopening Trump described.

Nothing physical has changed. Hormuz remains blockaded; naval enforcement now stands at 35 vessels redirected, 2 disabled, 2 boarded, up from 24. No fresh transit count has emerged since the ~14 vessels/day logged July 29. This is the second time in a week this pattern has produced a 5%+ drop (see July 27), and that earlier move partially reversed once transit data failed to confirm improvement. Watch transit counts, not statements, for confirmation either way.
