Iran signals attacks on U.S. ships, firms over sanctions pressure
Severity: WARNING

Summary
Iran’s Security Council Secretary Rezaei publicly threatened to attack U.S. commercial/drilling companies and U.S. naval vessels across the Indian Ocean if Washington obstructs Iran’s commercial and financial relations. The rhetoric materially raises the risk premium around Gulf/Hormuz traffic and U.S.-linked offshore energy assets, even without an overt move toward closure of Hormuz beyond existing alerts.
Details
Iran’s Security Council Secretary Rezaei stated that if the U.S. obstructs Iran’s commercial and financial relations, Tehran will “definitely attack American companies — such as the American drilling companies that operate extensively around us, American commercial companies”, and further warned that if war resumes, U.S. ships in the Indian Ocean would be attacked unless they leave. He also highlighted advances in hypersonic and electronic warfare capabilities. These comments go beyond generic anti‑U.S. rhetoric and explicitly threaten commercial and naval targets over economic pressure, directly linking sanctions enforcement to kinetic retaliation.
On the supply side, the immediate flow of oil and gas is unchanged, but the probability-weighted risk of disruption to seaborne energy logistics rises. U.S.-flagged, U.S.-owned, or U.S.-insured tankers and offshore assets in the Gulf/Arabian Sea basin are now being explicitly named as potential targets. That pushes up expected costs (insurance premia, war risk surcharges, rerouting) and could prompt risk-averse owners to reduce exposure or adjust routes even without formal sanctions changes or new attacks.
The key market transmission is via risk premium on crude benchmarks and regional shipping. In comparable episodes — e.g., the 2019 Gulf tanker attacks and the 2020 U.S.–Iran escalation after Soleimani’s killing — similar threat postures, even absent immediate large-scale disruption, were sufficient to move Brent and WTI several percent intraday as traders repriced tail risks of wider conflict or shipping disruption. Here, the remarks dovetail with existing heightened tensions and prior Iranian/IRGC-linked rhetoric on extending conflict to U.S. assets and Gulf traffic, reinforcing, not relaxing, that risk structure.
Directionally, this supports higher Brent and WTI (risk premium), wider war-risk insurance spreads, and safe-haven demand in gold and JPY. It may also weaken EM FX and sovereign credit in Gulf states deemed exposed to a U.S.–Iran clash. The impact is likely to be persistent while U.S.–Iran tensions remain elevated, with episodic spikes around any concrete incident involving U.S.-linked energy infrastructure or naval assets. Structural risk premium could remain in crude for weeks to months unless there is a clear de-escalatory signal.
AFFECTED ASSETS: Brent Crude, WTI Crude, Oil tanker dayrates, War risk insurance premia (Gulf/Indian Ocean), Gold, USD/IRR, GCC sovereign CDS, USD/JPY
