SCENARIO PROBABILITIESUpdated: Jul 1, 2026
Probabilities reflect the gap between declaratory IRGC threat language and observable behavior as of July 1 morning. No Hormuz-specific action has followed the Lebanon flare-up; deal-collapse probability from the July 1 SITREP (35-45%) is treated as the pre-Lebanon base rate, adjusted here for the added tail risk this report models.

Hardliner Unilateral Invocation5%
IRGC suspends Hormuz cooperation for domestic reasons, independent of Beirut$78-82
Hezbollah declared its ceasefire with Israel void on June 30, then launched the heaviest barrage of the post-ceasefire period: a missile aimed at Ashdod Naval Base, rocket fire into northern Israel, and one confirmed fatality. That is a Lebanon story. It became a Hormuz story the moment the IRGC repeated a sentence it first issued June 29: any ceasefire violation suspends all related processes. Nobody in Tehran has said the word Hormuz in connection with Beirut. Nobody has to. The ambiguity is the point. Today's brief covers Wednesday's toll booth rejection and the mine clearance clock; this report models what happens if Iran's hardliners decide those two sentences are the same sentence.
DEVELOPMENTS SINCE THIS BRIEF
JUL 2+1DAY
Day 125: Crisis Fatigue Prices In as Brent Hits Five-Month Low
Brent and WTI slid to five-month lows Thursday on trend continuation, not a new shock, while Hormuz transits held the low end of the vessel plateau and a US Navy helicopter's non-hostile water landing left one crew member missing. The Katz 48-hour window and a disputed $3 billion partial funds release both remain unresolved into Day 125.

Day 127: Iran Holds the Line, No Outside Help Clearing Hormuz Mines
Iran's deputy foreign minister maintains that clearing the ~80 mines still in Hormuz's central channel will be done solely by Tehran, rejecting a France-Oman demining offer with no sign of softening. Brent and WTI held flat near five-month lows on thin July 4 holiday trading, while the Doha talks stayed paused through the Khamenei funeral period and a UK-France military mission reaffirmation drew a sharp Iranian rebuke.
JUL 6+5DAYS
Day 129: France Pulls Its Carrier Home, Iran's Mines Still Sit Uncleared
France's Charles de Gaulle carrier group is heading back to Toulon while its mine-countermeasure assets stay in the Gulf, a partial drawdown that leaves Hormuz's ~80 uncleared mines untouched. Brent eased on a confirmed OPEC+ August hike that is more than half stranded behind the stand-down, and Khamenei's main funeral procession drew an estimated 15-20 million mourners in Tehran ahead of the July 9 Mashhad burial.
