Iran has attacked at least 15 container ships in the Strait of Hormuz over the past 10 days, resulting in the sinking of two vessels and pushing global oil prices to over $106 per barrel for Brent crude.

This escalation in maritime hostilities threatens a critical global trade chokepoint, disrupting supply chains, increasing transport costs for goods, and posing a risk of intensified inflation, especially for economies dependent on imported oil and goods.

What the records show

The Singapore-flagged container ship GFS Pride sank on October 14, 2026, after being struck by projectiles near the Strait of Hormuz. Singaporean authorities reported a fire on board as the cause of the sinking, stating that all 21 crew members were safely evacuated. However, Iran's navy offered a different account, claiming the GFS Pride hit a sea mine after veering into an unauthorized route. The vessel carried over 2,500 containers. Following its sinking, hundreds of Iranian fishermen were observed collecting spilled cargo, including iPhones and perfumes, from the Strait.

Another vessel, the Antigua and Barbuda-flagged dry bulk carrier Cape Dao, also sank. This ship had been damaged in an earlier attack on September 23, 2026.

The ongoing disruptions have directly impacted global energy markets. Brent crude futures rose to $106.08 a barrel, while U.S. West Texas Intermediate (WTI) crude climbed to $98.05. Some reports indicated Brent crude reached $109.90 and WTI $101.40. Shipping costs and insurance premiums have also surged. War-risk insurance premiums for transits through the Strait of Hormuz reached between 5% and 9% of a hull's value by late September 2026, a substantial increase from a pre-war baseline of approximately 0.25%. Maersk, a major shipping company, announced on October 8, 2026, it would impose an additional fee of USD 1,000 per container for vessels transiting the Strait of Hormuz to cover increased insurance and crew risk compensation.

The timeline

Attacks on commercial shipping in the Strait of Hormuz have intensified in the past 10 days leading up to October 19, 2026.

  • September 23, 2026: The dry bulk carrier Cape Dao was damaged in an attack. It later sank.
  • Late September 2026: War-risk insurance premiums for Hormuz transits reached 5% to 9% of hull value.
  • October 8, 2026: Maersk announced an additional USD 1,000 fee per container for Strait of Hormuz transits.
  • October 13, 2026: The Singapore-flagged container ship GFS Pride was struck by projectiles.
  • October 14, 2026: The GFS Pride sank.

What changed and for whom

The Strait of Hormuz, which handles approximately one-fifth of global petroleum liquids consumption, or about 20 million barrels of oil per day in 2024, is experiencing severe disruption. The increased costs of shipping, insurance, and fuel are raising concerns about inflation and liquidity pressures globally, particularly affecting oil-importing economies in regions like Africa. Higher demand for dollars, weaker local currencies, and increased costs for transporting goods and producing food are anticipated. The Persian Gulf is also a significant hub for global fertilizer production and exports.

What the subject has said publicly

Iran states that its actions in the Strait of Hormuz are a direct response to US blockades of Iranian ports and economic sanctions. Iran's latest proposal for reopening the Strait of Hormuz calls for the United States to end its naval blockade of Iranian ports.

What we could not confirm

PrimaryBrief could not confirm the exact nature of the projectiles that struck the GFS Pride or the number of casualties, if any, from the attack on the Cape Dao beyond the report of one sailor killed. The United States has not formally responded to Iran's latest proposal for reopening the Strait of Hormuz.
