Oil tanker hit by two unidentified projectiles off Oman, UKMTO says

The key detail is the location: this happened in the Gulf of Oman near the Strait of Hormuz, the chokepoint for a large share of seaborne crude, so even an attack with no casualties or pollution carries outsized weight for shipping and energy risk pricing. The fact that the projectiles are unidentified leaves attribution open, which is exactly the ambiguity that tends to widen war-risk insurance premiums and rerouting decisions before any formal blame is assigned. Whether insurers and operators treat this as an isolated incident or part of a pattern is the open question to watch.
