Operation Epic Fury: Week 6 β Ceasefire & Two-Week Truce
Bottom Line Up Front
The Iran conflict produced a fragile two-week ceasefire on 7-8 April after weeks of escalating infrastructure strikes. Trump set an 2000 EST 7 April deadline threatening destruction of all Iranian power plants. Hours before the deadline, the US and Iran agreed to a Pakistan-brokered truce, with Iran committing to reopen the Strait of Hormuz. The ceasefire took effect on 8 April but was immediately tested: Israel launched its largest strikes on Lebanon since the war began, killing over 250 people, prompting Iran to briefly re-close the Strait. As of 9 April, the ceasefire holds between the US and Iran but does not cover the Israel-Lebanon front. Negotiations are scheduled to begin in Islamabad on 10 April.
The conflict's cumulative toll now exceeds 3,400 killed across the region. Pentagon data indicates more than 380 US service members wounded in action since Operation Epic Fury began. CENTCOM has struck over 13,000 targets and flown more than 13,000 combat sorties. Brent crude dropped below $95/bbl on ceasefire news after trading above $108-116/bbl for much of the week. Lloyd's List confirmed only three ships transited the Strait in the 24 hours after the ceasefire announcement.

What We've Observed
Escalation Leading to Ceasefire (6-7 April)
Trump extended the 6 April energy infrastructure deadline by approximately 20 hours, setting a revised hard deadline of 2000 EST 7 April. Iran's Foreign Ministry stated that "negotiation is in no way compatible with ultimatum, crime, or the threat to commit war crimes." Hours before the deadline, Trump warned that "a whole civilisation will die tonight" if Iran did not agree to a deal.
On 6-7 April, the IDF issued public warnings to Iranian civilians to avoid trains and railway lines. The Yahya Abad bridge in Kashan was struck, killing two. US forces conducted a second major strike campaign on Kharg Island, hitting dozens of military targets while again sparing oil infrastructure. In response, Iran announced its restraint in targeting regional oil and gas infrastructure would no longer apply.
A joint US-Israeli strike on 5-6 April killed Major General Majid Khademi, head of the IRGC Intelligence Directorate and effectively the No. 2 within the IRGC, alongside Quds Force special operations commander Asghar Bagheri (Unit 840). This was the most significant leadership decapitation event since the killing of Ali Larijani in mid-March.
By 8 April, General Caine reported CENTCOM had struck over 13,000 targets, destroyed approximately 80% of Iran's air defences, hit 450+ ballistic missile storage facilities and 801 drone storage facilities, and rendered 155 naval vessels inoperative. Cumulative US WIA now exceeds 380 across all branches, with the majority suffering traumatic brain injuries. The US has lost at least ten manned aircraft since the conflict began.
Iranian Retaliatory Posture (6β7 April)
Iranian attack waves declined to approximately 7.7 per day from a campaign average of 12.4. Cumulative launches against the UAE reached 414 ballistic missiles, 15 cruise missiles, and 1,914 UAVs. Strikes continued against Gulf energy infrastructure including Kuwait's Ministry of Oil, power stations, and Bahrain's Bapco refinery. Iran's Atomic Energy adviser warned of potential extension to the Bab al-Mandab Strait in coordination with the Houthis.

A UN panel confirmed Strait of Hormuz transits dropped from approximately 130 per day in February to 6 per day in March, a decline exceeding 95%. Approximately 2,000 vessels and 20,000 seafarers remained stranded. Secretary Hegseth revealed Iran had been "obsessed" with striking a US aircraft carrier throughout the campaign but "never got even close."
Ceasefire & Diplomatic Developments (7β9 April)
Hours before the 2000 EST 7 April deadline, Trump announced the US would suspend strikes for two weeks, conditioned on Iran reopening the Strait of Hormuz. Pakistan brokered the agreement, with PM Sharif confirming the ceasefire and inviting delegations to Islamabad for 10 April. Iran confirmed it would allow safe passage through the Strait during the truce, provided vessels coordinate with Iranian authorities
The ceasefire was immediately contested. Israel launched its largest single-day strikes on Lebanon since the war began on 8 April, killing over 250 people. Netanyahu stated the ceasefire does not cover the Israel-Hezbollah front. Iran accused the US of violating the framework and briefly announced Strait re-closure in response to continued Israeli attacks on Lebanon. The White House denied any violation and said Strait traffic had increased. Lloyd's List reported only three ships had transited in the 24 hours following the announcement.

Iran and the US issued contradictory accounts of the agreement's terms. Iran's Supreme National Security Council stated Tehran had forced the US to accept its 10-point plan including continued Iranian control of the Strait, acceptance of enrichment, sanctions relief, compensation, and a halt to all fronts including Lebanon. US officials said the plan published by Iran was not the one approved as a basis for talks. VP Vance stated Iran had "misunderstood" the terms.
Markets reacted sharply. Brent crude dropped below $95/bbl, falling as much as 16%. The Dow surged 1,300 points. Asian markets rallied with Seoul up 6.9%, Tokyo 5.4%. Oil prices remain well above the pre-war baseline of approximately $65/bbl. Trump announced he would work with Iran to "dig up and remove" nuclear material buried during US bombings, and threatened a 50% tariff on imports from any country supplying weapons to Iran.
Why This Matters
The ceasefire is the most significant diplomatic development since the conflict began but remains structurally fragile. The fundamental gap persists: Iran views the Strait and its uranium stockpile as its two primary deterrents while the US and Israel require both resolved as conditions for any permanent deal. Israel's exclusion of Lebanon from the ceasefire creates a direct mechanism for collapse, as Iranian retaliation for Israeli strikes on Hezbollah could trigger Strait re-closure and US re-engagement.
Iran's declaration ending restraint on Gulf energy infrastructure following the 7 April Kharg Island strike remains the most consequential threshold crossed. If the ceasefire collapses, probable targets include Saudi Aramco's Ras Tanura and Abqaiq, Qatar's Ras Laffan LNG, and UAE refining capacity at Ruwais. Any coordinated campaign against these would likely produce the $200/bbl scenario and drive a global recession.
The F-15E shootdown and loss of ten US manned aircraft since the conflict began represents a politically and operationally significant attrition rate for a campaign expected to be largely one-sided in air losses. The simultaneous killing of Khademi and Bagheri removes two of the most operationally significant surviving IRGC figures at a time when regime coherence is under maximum pressure. Mojtaba Khamenei and IRGC commander-in-chief Vahidi have not been seen publicly since the war began.
What's Next?
The Islamabad negotiations beginning 10 April are the most significant variable for the next two weeks. The gap between Iran's stated terms and US-Israeli conditions makes a comprehensive deal within the ceasefire window unlikely. Watch for whether either side can identify partial confidence-building measures, particularly on Strait transit volumes, that allow the truce to hold.
Israel's continued strikes on Lebanon are highly likely to remain the primary friction point. Iran explicitly stated a Lebanon ceasefire was a condition of the deal. If Israeli operations produce mass casualties or expanded ground incursion, Iranian re-closure of the Strait is a realistic possibility, which would collapse the broader framework.
The Bab al-Mandab threat should be assessed as a signalling tool, but Houthi capability to close that waterway is well established. If the ceasefire collapses and Houthis act on Iranian direction to escalate Red Sea interdiction, two simultaneous chokepoint closures would produce supply shock conditions beyond current energy market pricing models.
Even if the ceasefire holds and the Strait progressively reopens, oil markets will remain undersupplied for months due to damaged infrastructure across the region. The IEA has described the disruption as worse than the 1970s oil shocks combined. Strategic reserve releases have provided a floor but cannot substitute for sustained Gulf production and export capacity.
Probability language: remote (<5%), unlikely (5β20%), realistic possibility (20β50%), likely (50β75%), highly likely (75β95%), almost certain (>95%).
