The Joint Maritime Information Centre (JMIC) has upgraded the Strait of Hormuz threat level to 'Substantial,' citing IRGC activity including the deployment of naval mines, GPS jamming, drone operations, and calls to vessels. The assessment warns of increased risk to commercial shipping.
On Tuesday evening, the Joint Maritime Information Centre (JMIC) — a multinational intelligence-sharing body — upgraded the maritime threat level in the Strait of Hormuz to 'Substantial.' The move follows Iranian Revolutionary Guard Corps (IRGC) activity in the strategic waterway, specifically the use of naval mines, GPS spoofing and jamming, drone sorties, and radio calls to vessels in the area.
This is the latest in a series of escalatory steps by the IRGC in the strait. Over the past month, the IRGC has fired warning shots at several ships, maintained a continuous fast-attack craft presence, and threatened force against unauthorized vessels. The JMIC's previous threat level, set at 'Moderate' or lower, was raised after a spate of incidents including warning shots and the IRGC Navy's declaration of full control over transit.
The new 'Substantial' rating signals a heightened risk of direct engagement against commercial shipping, though no specific attack has been reported as imminent. The assessment is based on reported IRGC activity and remains a single-source report; no immediate disruption to tanker traffic has been confirmed.
