Maritime experts say commercial vessels are likely to continue navigating the Strait of Hormuz despite escalating attacks, as strong demand for Middle Eastern energy and commercial opportunities keep some operators willing to take the risk.
The latest attacks targeted two Singapore-flagged container ships: GFS Pride sank after being struck by a projectile and catching fire, while GFS Giselle was damaged. Crew members from both vessels were reported safe.
Collin Koh, a senior fellow at Singapore's S. Rajaratnam School of International Studies, said shipping companies would probably keep looking for opportunities to use the strait.
"I don't see in the short term, that Singapore flagged ships or Singapore shipping companies would necessarily avoid taking the transit if there is an opportunity," Koh told CNBC.
Data from maritime analytics firm Kpler show crossings through the strait fell to 131 in the week ended Oct. 14, from 176 the previous week, although the decline cannot be attributed solely to the latest incidents. Dimitris Ampatzidis, Kpler's maritime risk and compliance manager, said the attacks underscored Iran's continuing ability to threaten commercial vessels, with risks extending beyond oil and gas transportation.
Strong demand for oil, particularly from Asia, continues to give tanker operators an incentive to carry energy supplies from the Persian Gulf, even as security threats complicate voyages. Singapore Foreign Minister Vivian Balakrishnan, speaking at the Milken Institute Asia Summit last week, recounted a conversation with an unnamed Gulf counterpart who said his country was earning more from oil exports than before the war by running a "Hormuz shuttle" of about 20 very large crude carriers, effectively self-insured against attacks.
"Sometimes you get hits, but it is still worthwhile to run the 'Hormuz shuttle,'" Balakrishnan quoted the official as saying.
The Singapore Shipping Association played down the prospect of a broad withdrawal of commercial shipping from the region, suggesting operators would instead adapt to changing trade conditions. Analysts cautioned that further attacks could deter more operators, with the impact likely to vary by vessel type and each company's assessment of the risks.
