Oil tanker traffic through the Strait of Hormuz has slowed to a near standstill as renewed military clashes between the United States and Iran threaten a fragile three-week-old truce. With major shipping risks escalating following targeted strikes on commercial vessels and renewed airstrikes on Iranian soil, the future of this vital global maritime chokepoint remains deeply uncertain.
Escalating Attacks on Commercial Shipping
The latest maritime crisis centers on a series of attacks against commercial vessels transiting the strait. Since the US-Iran ceasefire signed on June 17, at least five commercial ships have been targeted in or near the waterway. The most recent flare-up occurred between July 6 and July 7, involving three separate incidents.
The Marshall Islands-flagged LNG tanker Al Rekayyat was struck by a projectile, which ignited a fire in its engine room. While the vessel remains stranded off the coast of Oman, industry sources indicate that the risk of an explosion remains low and its cargo is secure. Other affected ships include the Saudi-flagged supertanker Wedyan and the Liberian-flagged M/T Cyprus Prosperity, both of which sustained damage during transit, as reported by Aljazeera.
Stagnant Traffic and Risk Perception
Ship tracking data reveals a stark decline in activity. Before the conflict began on February 28, the strait saw an average of 125 to 140 daily sailings. Even during the brief reopening period following the June 17 memorandum of understanding (MoU), traffic struggled to recover, averaging only 28 ships per day. By Thursday, July 9, activity had dwindled to near zero, with Reuters reporting that only two tankers—the Berg 1 and the Well Sail—had transited the strait in the early morning hours.
Industry experts suggest that this paralysis is a direct reflection of how the market views the current danger. Many shipping companies have opted to switch off their public AIS tracking transponders to avoid detection, further complicating efforts to gauge the true volume of remaining trade.
The Legal and Diplomatic Fragility of the MoU
The diplomatic framework intended to restore order is now under intense scrutiny. Legal experts point to the inherent weaknesses in the mid-June agreement, which failed to provide clear parameters for vessel protection in contested waters. “The MOU was vague, particularly on issues surrounding the Strait of Hormuz,” noted Jennifer Parker, a maritime security expert at the University of New South Wales. Parker added that the agreement, even under a favorable interpretation, provides no legal basis for Iran to conduct attacks on civilian shipping within Omani waters.

The situation is further complicated by Iran’s Revolutionary Guards Navy, which has warned that any further U.S. intervention in the region will draw a “crushing response.” Tehran claims that the U.S. has been disrupting the strait’s reopening by redirecting shipping, an accusation that mirrors the rising tensions as both nations trade airstrikes on domestic infrastructure.
Marine War Insurance and Financial Stakes
The insurance sector is responding to the volatility by tightening policies and advising clients to avoid the area. According to ship broker Clarksons, the prospect of a stable reopening for the strait looks increasingly unlikely. “The Hormuz reopening story looks more fragile after the latest escalation,” the firm stated in a recent report.
Marine war underwriters are now grappling with the reality of potentially massive financial exposure. One underwriter, speaking on condition of anonymity to Reuters, emphasized the severity of the threat: “As recent incidents have shown, the (marine war) market is now facing the prospect of potentially severe losses involving vessels of substantial value.”
Future Outlook for Global Energy Transit
The Strait of Hormuz remains a critical artery for the global economy, historically facilitating the passage of roughly 20 million barrels of oil and petroleum products daily—about one-fifth of global consumption. With the current truce described by U.S. leadership as effectively “over,” the immediate future of the waterway is dominated by the risk of returning to a full-scale naval blockade.
Approximately 6,000 seafarers remain stranded in the Gulf, caught in the crossfire of a conflict that has now spanned four months. As the U.S. and Iran continue to strike military and coastal targets, the industry is watching for further escalation in the Gulf. The primary indicator of the conflict’s next phase will be whether shipping lines continue to seek alternative routes or if the remaining vessels in the region attempt to navigate the chokepoint under increased naval escort.
