**Summary**: Reports that Iran aims to ban U.S. and Israeli vessels from the Strait of Hormuz and levy tolls on other traffic materially raise the probability of Gulf shipping disruption. Even without immediate implementation, this shifts risk premia higher for crude and LNG tied to Gulf flows.

## Detail

Iranian-linked sources report that Tehran is seeking to ban U.S. and Israeli ships from the Strait of Hormuz and to impose a toll regime on other vessels transiting the chokepoint. While this is not yet a formal, enforced policy, it marks a significant rhetorical and policy escalation around the world’s most critical oil and LNG transit route.

Roughly 17–20 million bpd of crude and condensate and about a quarter of global LNG trade move through Hormuz. Any credible threat of discriminatory access or new fees directly targets the cost and reliability of these flows. A hard ban on U.S. and Israeli-flagged ships is logistically manageable for large Gulf exporters (who can reflag or use neutral carriers), but it sets a precedent for selective harassment or interdiction. More significant is the toll concept: a unilaterally imposed fee would likely be rejected by Western governments and insurers, raising the odds of miscalculation, interdictions, or military escorts.

In market terms, the announcement alone is likely to add a geopolitical risk premium to Brent and Dubai benchmarks as traders price a higher probability of future disruptions, insurance cost increases, and delays. Front-month Brent and Oman/Dubai spreads are most exposed, with backwardation potentially steepening if war-risk premia rise. LNG spot prices in Asia (JKM) could also see a bid on fears of higher freight and insurance costs, even absent actual volume loss.

There is precedent: previous Iranian threats to close or manipulate Hormuz (2011–2012 sanctions episodes and 2019 tanker incidents) typically added several dollars to Brent on a risk-premium basis, even when volumes continued to flow. The current move comes against a backdrop of broader regional escalation and reported Iranian coordination with Houthi and Iraqi militias, increasing its credibility.

The impact is primarily risk-premium rather than immediate supply curtailment, but if followed by concrete enforcement steps—boarding, detentions, or attacks on non-compliant shipping—the move could quickly escalate into a multi-million-bpd at-risk scenario. For now, expect a short- to medium-term uplift in oil and LNG risk premia, sensitive to subsequent Iranian and U.S./Gulf naval actions.
