• Shipping traffic through the Strait of Hormuz has plummeted following recent US-Iran hostilities.
• More than 500 ships passed through since the June 17 MoU, but many remain stranded.
• Conflicting interpretations of the MoU have escalated tensions between the US and Iran.
• No vessels used US-recommended routes since July 7 due to fears of attacks.
• Analysts warn of potential long-term implications for global energy markets if the conflict persists.

Shipping activity in the Strait of Hormuz has crashed dramatically as renewed fighting between the United States and Iran escalates. No large vessels have crossed through the US-coordinated maritime route since July 7, with Lloyd's List Intelligence reporting that traceable crossings have "effectively ground to a halt" after recent hostilities, highlighting the strategic importance of this vital waterway for global energy supply. Before the conflict began, roughly 130 vessels transited the strait daily, and this disruption has cast a shadow over global energy markets, already strained by ongoing supply issues, according to Al Jazeera.

The US and Iran signed a memorandum of understanding (MoU) on June 17 to restore shipping and end their conflict, but conflicting interpretations of the agreement have reignited tensions. Iran perceives control over the Strait as a strategic advantage and insists on a unilateral right to essential maritime oversight, while the US advocates for free passage as previously established. Since the ceasefire, several attacks have been reported against shipping vessels that did not conform to Iranian guidelines, leading to retaliatory strikes by the US and significantly decreasing shipping traffic through the strait. This escalating cycle of violence underscores the delicate situation in the region, according to Le Monde and Al Jazeera.

Reports indicate that since June 17, over 500 ships have passed through the Strait, but many remain stranded due to fears of attacks, particularly since US strikes on Iranian targets resumed. The first major incident following the ceasefire occurred on June 25 when the Ever Lovely was struck, prompting US counterstrikes and further hostilities. Analysts suggest that the profound impact of the MoU's vagueness on maritime operations has led to this latest cycle of violence, complicating shipping routes and ensuring continued conflict, according to Al Jazeera and BBC.

Recent days have seen no tranquility in the strait as Iran and the US reportedly exchange fire, exacerbating concerns in an already fragile global oil market. On Thursday, Iranian forces responded to US strikes with missile attacks targeting US assets across the Gulf region, further heightening fears of an escalating conflict. Following these attacks, the volume of overall shipping through the area diminished significantly, with only five vessels tracked on Wednesday after reaching as many as 130 prior to the initiation of conflicts, reflecting the immediate repercussions of renewed military engagement in the region, as noted by Al Jazeera and Le Monde.
