Iran’s Revolutionary Guards have struck three oil tankers attempting to transit the Strait of Hormuz, according to reports from Radio Télévision Suisse citing the Tasnim news agency.

The attacks mark a sharp escalation in violence after several days of relative calm in the region, directly targeting commercial shipping in one of the world’s most critical energy chokepoints.

Brent crude and WTI futures are under pressure as traders reassess the risk of supply disruption.

The Strait of Hormuz handles roughly a fifth of global oil consumption, and any sustained interference with tanker traffic could trigger immediate price spikes and force insurers to raise premiums for vessels in the region.

The move by the ideological arm of Iran’s military suggests a willingness to escalate tactics beyond state-to-state military exchanges, directly threatening commercial infrastructure.

The development complicates a fragile diplomatic backdrop.
