Iran allows 23 ships through Hormuz, warns hostile nations
Severity: WARNING

Summary
Iran’s IRGC Navy reports that 23 ships have transited the Strait of Hormuz with more expected in coming hours, while reiterating that vessels from ‘hostile’ countries are prohibited. This signals a de facto, selective reopening of a chokepoint previously described as closed, which should ease some physical flow anxiety but keeps a strong geopolitical risk premium in place. Energy markets will interpret this as incremental relief for regional crude and LPG logistics rather than a full normalization.
Details
Iran’s Revolutionary Guard Corps Navy has announced that 23 ships have crossed the Strait of Hormuz and that additional vessels are expected shortly, while simultaneously warning that transit by ships from ‘hostile’ countries remains prohibited. This marks a tangible shift from prior reports of a broad closure of Hormuz that had driven a sharp spike in global LPG prices and supported a significant security premium in crude benchmarks.
Operationally, the passage of 23 vessels indicates that Iran is permitting at least some controlled commercial traffic, likely prioritizing neutral or friendly-flag energy cargoes and possibly essential goods. This eases the immediate risk of a hard stop in flows from the Persian Gulf and adjacent areas, particularly for LPG, condensate, and potentially crude exports from regional producers whose cargoes can be classified as non‑hostile under Iran’s criteria. However, the explicit prohibition on ships from ‘hostile’ states means the chokepoint remains politicized and selectively weaponized.
For markets, this is modestly bearish versus worst‑case scenarios. The earlier confirmed closure had raised the possibility of significant short‑term supply dislocations—potentially millions of barrels per day of at‑risk crude and large fractions of global LPG exports. A selective reopening calms fears of imminent physical shortages and may narrow the extreme spikes in LPG benchmarks and insurance premia, while reinforcing the view that Iran intends to use Hormuz as a calibrated pressure tool rather than a blunt blockade.
The directional bias is toward lower flat prices and narrower time spreads for Brent and related benchmarks compared with the height of the closure scare, complementing the impact of the reported Iran–US draft framework. However, given Iran’s ongoing threat posture toward ‘hostile’ shipping, war‑risk insurance and freight rates for US‑, UK‑, and some EU‑linked vessels and cargo interests are likely to remain elevated. Historical experience from partial disruptions (e.g., tanker harassment episodes in 2019) suggests that even when transit continues, markets price a persistent risk premium as long as military forces remain in close proximity and rules of engagement are uncertain.
The impact should be viewed as a near‑term easing of acute risk (days to weeks), not a structural resolution. Any incident involving a ‘hostile’ vessel, or a breakdown in parallel Iran–US talks, could quickly reverse sentiment and re‑tighten the premium.
AFFECTED ASSETS: Brent Crude, WTI Crude, Dubai Crude, LPG benchmarks (FEI, CP), VLCC and product tanker freight (AG routes), War-risk insurance premia, Middle East refined product spreads
