An oil tanker sailing near the Strait of Hormuz was struck by an unidentified projectile and caught fire on Monday, according to the UK Maritime Trade Operations (UKMTO).
The incident occurred off the coast of Oman, a critical chokepoint for global energy flows, and has triggered immediate concern among traders monitoring shipping security in the region.
Brent crude prices rose sharply in the session as investors repriced the risk of supply disruption.
The attack underscores the fragility of the current truce in the strait, with markets reacting to the renewed threat against commercial vessels.
Tanker equities and shipping indices also saw upward pressure as risk premiums widened.
This event follows a recent escalation in tensions, with previous reports indicating missile attacks on commercial ships in the same corridor.
