Quick Summary

In October, at least 12 ships were attacked in or near the Strait of Hormuz, with UK Maritime Trade Operations noting many more unconfirmed incidents. The attacks come amid increased competition between the US and Iran for control over this strategic waterway, which sees about a fifth of global oil transit. While the US claims to maintain control with support from Arab allies, enabling 400 ships and 100 million barrels of oil to move through the strait weekly, Iran’s actions have disrupted traffic and raised oil prices to $110 per barrel for Brent crude.

Story summary

As of October 17, 2026, 12 ships reported being attacked in and around the Strait of Hormuz between October 5 and 11, setting a record high since the start of the US-Israeli war with Iran on February 28. The UK Maritime Trade Operations (UKMTO) agency documented six attacks on a single day, Sunday, which is unprecedented. Despite these incidents, 400 ships and 100 million barrels of oil moved through the strait over the past week according to US Central Command (CENTCOM). The increased ship attacks are attributed by CENTCOM chief Brad Cooper to "desperation" by Iran's Islamic Revolutionary Guard Corps (IRGC), which asserts broader control over maritime routes. However, the UKMTO notes that its ability to accurately report these incidents is hindered due to vessels refusing to provide information post-attack, leading to uncertainty about the total number of attacks.
