The Strait of Hormuz is having a very bad year. On July 20-21, an unidentified projectile, suspected to be a drone or missile, struck the Kuwaiti-flagged oil products tanker Kaifan near the strait’s eastern entrance, triggering a fire, knocking out engine power, and injuring two crew members.

Kuwait’s government responded by summoning Iran’s ambassador, signaling serious escalating tension between the two Gulf neighbors.

What happened to the Kaifan

The Kaifan is owned by Kuwait Oil Tanker Co., one of the region’s major state-backed shipping operators. The vessel issued a distress call during the attack, and while the two injuries were described as minor, the combination of fire and engine disablement in one of the world’s most strategically sensitive waterways is anything but minor in market terms.

No group immediately claimed responsibility, but the timing fits a broader pattern that has been building since late February 2026, when Iranian restrictions on vessel transit through the Strait of Hormuz first ignited what analysts are now calling the 2026 Hormuz Crisis.
