Day 103: Jordan Joins the Target Set, Brent Refuses to Price It
Iran downed a US Apache, the largest US strike night of the crisis followed, and Iran counterstruck three host nations including Jordan for the first time. Brent sat flat at $91 against a probability-weighted fair value of $105-112.
- US-Iran cycle probably closed: a calibrated ~20-target US package and a zero-casualty Iranian counterstrike across three nations; full war resumption rises to 18-24%, front-loaded into the next 72 hours
- Jordan struck for the first time, putting host-nation liability doctrine on the record; 40-50% odds at least one host imposes a basing or overflight caveat within two weeks
- Brent flat at ~$91 versus probability-weighted fair value of $105-112; Hormuz transits revised down to 2/day and the Red Sea has zero US carrier coverage

Trump Orders Second Strike Night; Tanker Hit Off Oman Leaves One Crew Dead

ENFORCEMENT: Houthis Strike Multiple Vessels in Gulf of Aden -- Bab el-Mandeb Now Active Interdiction Zone
Houthis move from declaration to live fire. MV Norderney struck twice, MSC Tavvishi struck, third vessel hit near Djibouti. The Red Sea is now an active interdiction zone for Israeli-linked shipping -- and vessels with ambiguous flag exposure face interdiction risk.

Three Strikes in 24 Hours: Bab el-Mandeb Closing Fast
Houthi forces struck three vessels in 24 hours, including a double-hit on MV Norderney, as the Iran-Israel halt frays on its first full day. Red Sea fixture cancellation rate now 70-80% -- functionally a declared closure.
Day 101: Direct Fire
Iran fired ~20-30 ballistic missiles at Israel on June 7 -- the first direct attack since the April 8 ceasefire -- after the IDF killed Hezbollah's intelligence chief in Dahiyeh. Israel struck back. Lebanon's ceasefire has collapsed and the MOU track is effectively suspended.
Day 100: The Letter to the Supreme Leader
On the 100th day of the Hormuz closure, Pakistan's Interior Minister arrived in Tehran carrying a direct message from Army Chief FM Munir to Supreme Leader Khamenei. CENTCOM held fire overnight. Markets watched and waited at $93.
Day 99: The Fourth Deadline and the Expanding Target List
Trump's 'this weekend' MOU deadline passed without a signature. CENTCOM struck a new Iranian radar site at Goruk. Brent slipped to $93. Day 99 finds the deal alive but structurally stuck.
Day 97: Lebanon's Paper Ceasefire and the Road Back to the MOU
Israel and Lebanon agreed to a US-brokered ceasefire framework, the most direct response yet to Iran's June 1 precondition for resuming MOU talks. Hezbollah isn't a signatory and fighting continued overnight. Brent settled $96.97. MOU odds nudged from 8-10% to 12-15%.

The Insurance Weapon: How War-Risk Underwriting Closed the Strait of Hormuz
How soaring hull war-risk premiums, withdrawn charterers'-liability extensions, and a Lloyd's Listed-Area designation made Hormuz commercially unviable, an underwriting-driven de facto blockade that outlasted the military campaign even though core P&I cover never lapsed.
How the Ceasefire Happened, and Why It Hasn't Ended the War
The inside story of the Pakistan-brokered truce that halted the Hormuz War, and the 55 days of ceasefire since. A two-week pause became an indefinite ceasefire. The Islamabad talks collapsed. A naval blockade went up. Now the whole war hangs on a 60-day deal neither side has signed.
The 94-Day Balance Sheet
The full ledger of the Strait of Hormuz crisis at Day 94: military attrition, human cost, energy damage, global fallout, maritime paralysis, and a diplomatic endgame that left the bill paid but the ledger open. The shooting stopped without the war ending; the strait reopened on paper without functioning.
Tier 1 Watchlist
Iran
DAY 103 / STRIKE CYCLES: IRGC counterstrike cycles June 3/6/10 hit US facilities in three host nations including Jordan (a first); US Apache downed over Hormuz June 9; CENTCOM answered with ~20 targets; IRGC tripwire on record: further US strikes on Iranian soil = move to close Hormuz completely; Iran-Israel conditional halt since June 8; MoU 3-5%; transits 2/day; Khamenei comms reportedly disrupted (unverified)

Pakistan
Lead mediator of the crisis. On Day 100, Interior Minister Naqvi delivered a direct letter from FM Munir to Supreme Leader Khamenei -- Pakistan's most substantive diplomatic intervention since the April Islamabad Talks.
