Iran Conflict — 2026-03-23

Brent Crude Plunges 10% to $100/bbl as Markets Price In Hormuz Diplomacy; Dow Surges

Global oil markets reversed sharply after Trump announced 'productive conversations' with Iran, with Brent crude falling more than 10% from morning highs of $113/bbl to settle at $100.37/bbl. WTI crashed to $88.85. The drop marks the largest single-day decline since the conflict began on February 28. Wall Street rallied in response, with the Dow surging over 1,000 points. The relief may be premature: Iran's Foreign Ministry denied any dialogue exists, and the Strait of Hormuz remains effectively closed to uncoordinated commercial traffic. Shipping through the waterway has dropped more than 70% since the war began.

Analysis
Prior INTSUM tracked Brent at $108. The $100.37 close represents the first sustained drop below $105 since the war began. Markets are pricing in de-escalation faster than the military situation warrants; Hormuz remains effectively closed at 5-6 transits/day vs. 120+ normal.
