**Summary**: TeleSUR English reports that US forces are blocking 73 commercial vessels in Iranian ports, adding to the maritime paralysis created by the oil blockade. This broadens the disruption beyond crude exports to general trade flows, increasing regional shipping and insurance risk premiums and reinforcing oil market tightness expectations.

## Detail

TeleSUR English cites that US forces are currently blocking 73 commercial vessels in Iranian ports. While the report does not specify the cargo mix, in the context of the ongoing US naval blockade on Iranian oil and associated strikes on Iranian-flagged tankers, this suggests a wider interdiction of vessel movements in and out of Iranian harbors, not just enforcement against specific crude cargoes.

From a physical oil market perspective, the key implication is that Iran’s ability to use its port infrastructure for both loading and offloading is being systematically constrained. Even if some of these 73 vessels are non-oil cargoes, their immobilization ties up tonnage, clutters port approaches, and effectively reduces Iran’s operational export capacity and flexibility (e.g., using non‑traditional cargos or ship‑to‑ship operations as workarounds). Combined with earlier intelligence that approx. 166 million barrels of Iranian crude are already frozen by the blockade, this contributes to a tighter supply outlook in the medium sour segment. It also raises questions about Iran’s import capacity for refined products and industrial inputs, which could feed back into domestic output and, eventually, OPEC+ policy dynamics.

In shipping and insurance, a de facto US-controlled exclusion zone around multiple Iranian ports will increase war-risk surcharges, drive up day rates on vessels willing to call the region, and divert some tonnage to safer routes. That supports higher freight benchmarks on AG–Asia and AG–Europe lanes and, via pass-through, somewhat higher delivered crude and product prices for Asian and European buyers.

Historically, coordinated interdiction of commerce (e.g., 2012–15 Iran sanctions tightening, Yemen-related Bab el-Mandeb risk spikes) has been associated with multi-percent adjustments in tanker equities, CDS spreads for Gulf sovereigns, and a modest safe-haven bid into gold and the dollar. Given this is unfolding alongside kinetic strikes on tankers and ongoing skirmishing in the Strait of Hormuz, markets are likely to treat it as a multi-week to multi-month regime change in Gulf maritime risk rather than a one-off event, maintaining an elevated risk premium in energy and regional assets.
