IRGC Condemns New Hormuz Route as ‘Perilous’, Tightens Radio Control on Shipping
Severity: WARNING

Summary
Iran’s Revolutionary Guard Navy on 25 June ordered vessels transiting the Strait of Hormuz to coordinate via Channel 16 and branded a newly announced shipping route, set without Tehran’s input, as “unacceptable and perilous.” The moves sharpen the risk of direct confrontations with foreign-flag tankers at the world’s most sensitive oil chokepoint, just as US crude futures slipped on higher Middle East supply.
Details
Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy has moved to reassert control over traffic in the Strait of Hormuz, a waterway that carries roughly a fifth of global oil trade, in a way that directly heightens miscalculation risk for commercial shipping and naval forces.
At around 01:16–01:18 UTC on 25 June, Iran’s Revolutionary Guards denounced a newly announced Hormuz shipping route that was set without Tehran’s coordination, calling it “unacceptable and perilous.” Minutes later, a separate report said the IRGC Navy has ordered vessels to coordinate via VHF Channel 16 when transiting the Strait, effectively signaling that Iranian forces expect direct radio contact and de facto oversight of movements through the chokepoint. These are OSINT-sourced claims, but they are consistent with past IRGC behavior when asserting jurisdiction in the Gulf.
For crews, insurers, and energy customers, the stakes are immediate. Any effort by the IRGC to challenge vessels using the “new” route, demand course changes, or treat non-compliant ships as violators will raise the probability of boardings, detentions, or near-collisions. Previous such confrontations have involved UK-, US-, and Gulf-flagged tankers and have quickly drawn in Western naval escorts. Even without shots fired, aggressive radio challenges or maneuvering in the constrained Strait—at its narrowest less than 40 km wide with designated traffic separation schemes—raise operational risk and insurance costs.
Security-wise, this marks an incremental but meaningful escalation. Rather than a one-off seizure, Iran is contesting the legitimacy of route planning itself and directing all vessels to a single channel of communication it can monitor and dominate. That gives the IRGC a structured pretext to stop or redirect ships under the guise of safety or compliance. It also creates an interaction point with US, UK, and Gulf naval vessels tasked with keeping lanes open, increasing the chance of misread intentions, especially at night or in high traffic.
Markets are already signaling sensitivity. Around 01:46 UTC, US crude futures were reported down $1.10 to $69.24 per barrel as Middle East producers ramp up supply, but that softness could flip rapidly if traders perceive that route disputes may evolve into selective harassment of tankers, LNG carriers, or flag-specific vessels. Any confirmed delay or diversion of cargoes through Hormuz would drive a risk premium into Brent and WTI, boost time-charter and spot tanker rates, and pressure insurers to adjust war risk surcharges. GCC currencies pegged to the dollar could see renewed scrutiny if export volumes look vulnerable, while safe-haven demand might lift gold and US Treasuries.
Over the next 24–48 hours, key indicators to watch include: (1) reports from shipping companies or maritime security firms of increased radio hailing, shadowing, or boarding attempts by IRGC boats; (2) statements from US Fifth Fleet, UKMTO, or regional navies either warning of interference or announcing convoy/escort measures; (3) changes in war-risk insurance pricing for voyages transiting Hormuz and the Gulf of Oman; and (4) any move by Iran to formally codify new “rules” for transit or by foreign states to issue counter-guidance to their flagged fleets. Any first confirmed interdiction of a major tanker or LNG vessel, especially from a G20 state, would likely push this situation into FLASH territory for both security and energy markets.
MARKET IMPACT ASSESSMENT: Elevated geopolitical risk premium around Gulf shipping; short-term downward pressure on crude from supply headlines may reverse quickly if any boarding, diversion, or near-collision occurs. Watch Brent/WTI spreads, tanker rates, and insurance premia for Hormuz transits, plus safe-haven flows to gold and dollar if confrontation escalates.
