Iran Strait of Hormuz warning adds to shipping uncertainty

Iran Strait of Hormuz Warning Adds to Shipping Uncertainty

The Iranian naval force has issued a caution to maritime vessels traversing the Gulf, stating that any ship attempting to cross the Strait of Hormuz without prior authorization “will be targeted and destroyed,” according to the shipping consultancy SSY. This alert comes amid a two-week truce brokered on Tuesday evening, contingent on ensuring “safe passage” through the narrow waterway. However, only a limited number of vessels have transited the strait since the agreement was announced.

Strait’s Strategic Role in Global Trade

The Strait of Hormuz, a vital chokepoint measuring roughly 33 kilometers at its narrowest, has emerged as a central battleground in the US-Israeli conflict with Iran. It serves as a critical route for approximately 20% of the world’s oil and liquefied natural gas. Over the past five weeks, disruptions in this passage have caused significant economic repercussions, driving up energy prices and highlighting the global economy’s dependence on the region’s shipping infrastructure.

Beyond energy, the strait is essential for transporting chemicals used in manufacturing microchips, pharmaceuticals, and fertilizers. Despite a recent drop in oil prices due to the ceasefire, shipping experts remain cautious, noting that the volume of crossings has not yet rebounded to pre-conflict levels. “Most carriers are still assessing the risks and waiting for clear guidelines on transit procedures,” explains Lars Jensen of Vespucci Maritime to BBC Verify.

Analysts Weigh in on Ongoing Challenges

As of 14:00 BST on April 8, only three bulk carriers—NJ Earth, Daytona Beach, and Hai Long 1—had successfully navigated the strait since the truce began late Tuesday. This figure, derived from BBC Verify’s analysis of MarineTraffic data, contrasts sharply with the average of 138 ships daily before the conflict erupted on February 28. The uncertainty surrounding the ceasefire’s effectiveness persists, as analysts debate whether the crossings are a result of the agreement or prearranged exceptions.

“It remains unclear whether this reflects a broader reopening or a limited exception,” says Ana Subasic from Kpler. “Nothing has really changed yet,” adds Jensen, emphasizing that crews still lack confidence in the strait’s safety.

Richard Meade, editor-in-chief of Lloyd’s List, highlights the continued peril for ship operators, stating, “This has been a very dangerous period for maritime owners, who still grapple with immense uncertainty.” He notes that Iran retains control over the strait, and the process for granting passage remains ambiguous. “The assumption is that vessels will need approval from the Islamic Revolutionary Guard Corps—yet the mechanics of that process are still unconfirmed,” Meade explains.

Remaining Risks and Operational Concerns

Uncertainty also surrounds the presence of sea mines, as Thomas Kazakos of the International Chamber of Shipping warns, “We must ensure clear confirmation of navigational safety for both ships and seafarers.” Additionally, reports suggest tolls may be part of the ceasefire arrangement, raising concerns for shipping lines about potential payments to Iran.

“The Iranian position appears to require tolls for passage, which could deter carriers from proceeding without certainty,” notes Jensen. Countries like India, Malaysia, and the Philippines have secured safe transit arrangements, but others may face complications due to US sanctions.

Analysts like Niels Rasmussen from BIMCO caution that the two-week ceasefire may not lead to a surge in traffic, as operators fear being stranded after the window closes. “A substantial influx is unlikely, given the risk of entrapment,” he says. Meanwhile, the focus remains on getting fully loaded tankers out of the region, with Meade predicting, “Stranded vessels will likely take precedence in resuming crossings.”
