**Summary**: Reports indicate the IRGC has effectively forced almost all tanker and cargo traffic in the Strait of Hormuz into an Iran‑controlled lane, emptying the traditional route along the Omani coast. This materially raises transit risk and the geopolitical risk premium on crude and products, even absent kinetic incidents so far.

## Detail

Multiple real‑time shipping intelligence reports state that over the past 24 hours, the Iranian Revolutionary Guard Corps (IRGC) has asserted full practical control over traffic in the Strait of Hormuz. Only one vessel reportedly transited via the usual route near the Omani coast, with the overwhelming majority now navigating through an Iran‑designated corridor under IRGC supervision, following earlier radio threats to ships attempting to use the Oman‑side route.

This represents a significant escalation from routine harassment: Iran has moved from sporadic interdictions to de facto traffic management in one of the world’s most critical chokepoints, through which roughly 17–19 mb/d of crude and condensate and sizeable volumes of refined products and LNG flow. While there are no confirmed new seizures or attacks in this specific update, the combination of explicit threats and forced rerouting dramatically increases perceived seizure and sanction‑related risks for flag states, insurers, and shipowners.

Supply itself is not yet physically curtailed, but effective capacity of the route is vulnerable. Key near‑term transmission channels are: (1) higher war‑risk premiums and insurance costs for any vessel transiting under IRGC observation; (2) potential self‑restraint or rerouting by Western or Gulf operators who may temporarily delay sailings; and (3) the sharply higher probability of a miscalculation or targeted interdiction triggering Western naval response and possible kinetic exchange.

Historically, episodes such as the 2011–2012 Hormuz threats and 2019 tanker attacks produced 3–10% short‑run moves in crude benchmarks via risk premium rather than outright loss of barrels. The current development is closer to 2019 in operational terms, but without confirmed damage yet. Markets will likely price in an incremental MENA geopolitics premium: supportive for Brent and Dubai spreads, for product cracks (especially Middle East–Asia MR routes), and for LNG freight sentiment.

Duration will depend on whether this ‘IRGC lane’ becomes normalized or is challenged by the US and Gulf navies. If sustained for weeks without incidents, the premium may partially fade but remain embedded in insurance costs. Any escalation (boarding, seizure, or strike) would quickly turn this from a risk‑premium story into a potential supply disruption, with scope for >5% upside in crude benchmarks.
