SCENARIO PROBABILITIESUpdated: Jun 28, 2026
Probabilities are assigned after recalibrating for the Bahrain/Kuwait strikes, which the prior model assigned 8% probability. The overnight escalation eliminates the benign-drift path that anchored Friday's $72-73 close. Deal-collapse probability is now 55-65% across scenarios B, C, and D.

CENTCOM Round 3; Iran suspends but does not withdraw$85-95
Iran exits Burgenstock; third vessel attack; insurance frozen$95-115+
Iran struck sovereign territory of two US-allied Arab states overnight. Missile and drone barrages hit Bahrain and Kuwait, producing shrapnel damage and air-raid sirens but zero casualties. The precision was deliberate. Tehran has demonstrated it can reach NSA Bahrain and Ali Al Salem Air Base without hitting them, which is a different kind of message than missing. The physical damage is irrelevant. The signal is not: Iran is willing to strike US-allied capitals, which expands the ceiling on every subsequent escalation decision both sides face. The key variable for the next 72 hours is Burgenstock attendance. If Iran sends even a junior delegate to Day 2, the diplomatic architecture holds. If they send no one, four months of negotiation dissolves and the oil market reprices by double digits.

Day 123: Diplomacy Shifts to Doha; the Mine Clearance Clock Does Not
The Burgenstock framework is on pause. Witkoff and Kushner are in Doha; Iran says there are no talks. The IRGC denied the hotline. None of that moves the mine clearance clock, which hits its critical threshold in 14 days.

Day 124: Vance Rejects the Toll Booth, Clock Down to 13 Days
Vice President Vance publicly rejected Iran's proposed Hormuz transit fee as unacceptable, the sharpest concrete US pushback yet on a specific Iranian demand. The rejection stalls the committee track meant to unlock mine-clearance authorization, with 13 days left before the late-August reopening window closes.

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.
