A collapsed ceasefire and three consecutive rounds of U.S. airstrikes have pushed Gulf shipping to a near standstill, with Tehran now claiming to have shut the strait to transit.

Iran's Islamic Revolutionary Guard Corps has declared the Strait of Hormuz closed to shipping following a third consecutive wave of U.S. airstrikes since the collapse of the February ceasefire. The escalation, triggered by an IRGC attack on a Cyprus-flagged container ship on 11 July, has driven tanker traffic through the world's most critical oil chokepoint to a near standstill and raised the probability of a sustained, multi-front regional war.

Situation Report

President Trump declared the ceasefire "over" on 8 July, speaking from the NATO summit in Turkey, after the IRGC struck three commercial vessels in the strait on 7 July — among them the Marshall Islands-flagged Qatari LNG carrier Al Rekayyat, which remains stranded off Oman awaiting salvage after a projectile strike ignited a fire in its engine room. The U.S. military responded within hours, confirmed to have struck approximately ninety targets inside Iran. Tehran retaliated with missile and drone strikes against U.S.-linked facilities in Kuwait and Bahrain.

A second wave of U.S. strikes followed on 9 July, with Iran retaliating against positions in Qatar, Kuwait, and Bahrain, per Cipher Brief reporting. A third wave came on 11 July: U.S. Central Command said the military struck approximately 140 Iranian military targets after the IRGC "blatantly attacked" a Cyprus-flagged container ship transiting the strait; one crew member is reported missing. Iranian state media declared the strait formally closed to transit following the strike, though independent verification of a full closure order — as distinct from continued high-risk selective interdiction — remains pending.

Tanker traffic has collapsed accordingly. Reported daily transits fell from a pre-war average of 125 to 140 vessels to roughly 40 in the weeks preceding the ceasefire collapse, and to as few as two tankers in the twenty-four hours following the 8 July strikes. The strait normally carries close to one-fifth of global oil supply.

A parallel diplomatic track continues. Iranian Foreign Minister Abbas Araghchi met his Omani counterpart in Muscat over the weekend, with Oman circulating a tentative proposal to manage strait traffic through two separately controlled corridors. Trump has since said he remains open to talks with Tehran even while maintaining the ceasefire is "over" — a position current reporting frames as strategic ambiguity rather than a coherent negotiating posture.

Background & Context

The current war originated on 28 February 2026, when the United States and Israel launched a coordinated air campaign against Iranian nuclear and military infrastructure. Iran responded by effectively closing the Strait of Hormuz to unauthorized transit, boarding and attacking merchant vessels, and laying sea mines — actions that have persisted intermittently through successive rounds of negotiated and collapsed ceasefires.

The February campaign followed more than a year of accumulated pressure, including earlier 2025 strikes that had already degraded elements of Iran's nuclear program and air-defence network without resolving the underlying standoff over enrichment capacity. Successive ceasefires brokered through regional intermediaries — Qatar, Pakistan, and now Oman — have proven durable in weeks rather than months.

The conflict has also metastasized regionally. Israeli forces remain deployed in southern Lebanon against Hezbollah despite a U.S.-backed phased-withdrawal framework, and Gulf host states — Kuwait, Bahrain, Qatar — have absorbed direct Iranian retaliatory strikes for hosting U.S. military infrastructure, shifting them from bystanders to active theatre participants.

Analysis & Assessment

SpyWitness assesses with high confidence that the ceasefire structure governing this conflict is no longer a durable mechanism, having failed three times within roughly five months under comparable triggering conditions: an IRGC strike on shipping followed by escalatory U.S. retaliation. The pattern indicates neither side currently possesses, or is prepared to exercise, sufficient escalation control to hold a truce absent sustained external compulsion.

Iran's declared closure of the strait is assessed with moderate confidence as a claim that outpaces current operational reality. IRGC statements of full closure have historically exceeded actual interdiction capacity; the more probable near-term condition is continuation of selective interdiction — strikes against vessels judged non-compliant with Iranian transit terms — rather than a hermetic seal. The distinction matters materially for oil-market and shipping-insurance modelling, where a "closed" designation and a "high-risk, partially open" designation carry very different premium and routing implications.

Oman's dual-corridor proposal is the most consequential development on the diplomatic track and should be weighted accordingly. It implicitly concedes that neither a full Iranian closure nor a full Western freedom-of-navigation posture is currently sustainable, and represents the first structural — rather than purely ceasefire-based — de-escalation mechanism proposed since February. Its adoption would mark a meaningful de-escalatory pivot; its rejection or collapse would likely presage a fourth strike cycle within days.
