Iran's Islamic Revolutionary Guard Corps (IRGC) has issued a stark warning to international shipping, stating that any vessel crossing the Strait of Hormuz without authorization "will be dealt with." The statement, reported by Asharq Al Awsat, marks a significant hardening of Tehran's rhetoric regarding the narrow waterway, which serves as a critical artery for global oil and gas flows.

The threat comes at a sensitive juncture for global energy markets.

Just days ago, reports indicated that Iranian officials had assured US counterparts that no tolls would be imposed on transit through the strait, a development that contributed to a slide in oil prices.

The IRGC's latest ultimatum directly contradicts the spirit of those diplomatic assurances, reintroducing uncertainty into the shipping corridor.

Market participants are now reassessing the reliability of Tehran's commitments, with the potential for sudden disruptions to tanker traffic remaining a primary risk factor.

This escalation follows a series of tensions in the region.
