A one-month truce between Washington and Tehran has effectively collapsed, with tit-for-tat strikes now threatening the world's most important oil chokepoint.

Intelligence Lead

Renewed exchanges of fire between US and Iranian forces around the Strait of Hormuz have overtaken the June memorandum of understanding that was meant to formally end the 2026 Iran war. CENTCOM has confirmed strikes against Iranian missile sites and naval assets used to threaten commercial shipping, while Iranian state media reports a projectile strike near Bushehr. The strait carries an assessed one-fifth of global seaborne oil, and continued disruption carries direct consequences for global energy markets.

Situation Report

Fighting resumed after Iranian forces attacked three commercial vessels transiting the Strait of Hormuz on 6–7 July, prompting US President Donald Trump to declare the truce "over" and authorise strikes against Iranian targets. US forces subsequently reinstated a naval blockade of Iranian ports in the strait, alongside strikes reported to be aimed at degrading Iranian capabilities used against commercial shipping.

A further tanker was struck in the strait on 22 July, according to regional reporting, and Iranian state media alleges a US-Israeli projectile hit a military facility near Bushehr the same day. CENTCOM has confirmed additional rounds of strikes described as intended to "hold Iranian forces accountable." Yemen's Houthi movement, an Iran-aligned actor, has separately threatened to impose its own naval blockade against Saudi Arabia, a signal that the confrontation risks drawing in additional regional actors beyond the direct US-Iran axis.

Regional mediators have presented both governments with a proposal for a 10-day ceasefire, an attempt to arrest the escalation and restore the framework agreed in June. Neither Washington nor Tehran has confirmed acceptance as of this writing, and both sides continue to exchange strikes while the proposal is under consideration.

Background & Context

The current crisis follows a five-week war between the US, Israel, and Iran that ended with an April ceasefire, after which a June memorandum of understanding sought to convert the truce into a durable settlement within sixty days. That memorandum did not resolve the underlying dispute over transit rights and security guarantees in the Strait of Hormuz, leaving the door open for the kind of maritime incident that reignited hostilities in early July.

The Strait of Hormuz has functioned for decades as a pressure point precisely because it cannot be easily bypassed: it is the only sea route out of the Persian Gulf for the region's major oil producers, and its narrowest shipping lanes run within a few miles of Iranian territory. Iran has previously used the threat of closure, rather than closure itself, as leverage in disputes with Washington. The willingness to strike tankers directly this cycle marks an escalation beyond that established pattern of signalling.

Analysis & Assessment

The reinstated US blockade and continued Iranian strikes on shipping suggest both sides currently assess the political cost of further escalation as tolerable, even as the economic cost to global energy markets rises. The involvement of the Houthis introduces a second front that Tehran can activate without direct attribution, complicating any ceasefire that addresses only the US-Iran bilateral track.

The 10-day ceasefire proposal is likely to be tested less by its terms than by its verification: a suspension of strikes without a parallel guarantee on tanker safety would replicate the ambiguity that undid the June memorandum. Analysts assess that a durable resolution requires either an enforcement mechanism with third-party monitoring in the strait or a broader diplomatic settlement that removes Iran's incentive to use maritime disruption as leverage. Absent either, further cycles of strike and re-strike through the northern autumn remain the more probable trajectory than a clean de-escalation.
