The Biden Administration Revives an 1860s Legal Mechanism to Seize Iranian Oil Cargoes
The U.S. government is applying a Civil War-era legal process to block Iranian oil shipments from reaching buyers worldwide, deepening tensions over Tehran’s oil trade. This approach centers on the Foreign Sovereign Immunities Act and the sue-and-attach procedure, which permits civil lawsuits to seize assets linked to terrorism or sanctions violations. The tactic, first deployed in the 1860s to target Confederate cotton, has now been used against oil from Venezuela, Russia, and Iran.
The process unfolds in three stages: the Treasury Department identifies sovereign-owned property, the Justice Department initiates freeze proceedings in federal court based on probable cause, and successful cases result in asset forfeiture, with proceeds funding the U.S. Victims of State Sponsored Terrorism Fund. This method circumvents international dispute resolution bodies such as the International Court of Justice.
In 2023, similar actions were taken against Venezuelan crude bound for Europe, where the DOJ invoked violations of executive orders E.O. 13692 and E.O. 13846. The strategy targets vessels flying flags of convenience or registered under third parties that enter U.S. ports or waters under American control. Legal scholars warn these actions could weaken protections for sovereign assets, while opponents argue the use of outdated legal tools for modern conflicts risks conflating legal enforcement with economic coercion.
Industry players are adjusting by rerouting shipments, engaging in barter arrangements, or shifting to cryptocurrency to evade dollar-based transactions. Iran maintains its exports are lawful under UN Charter Article 51, arguing U.S. actions constitute an illegal interference. While the broader goals of this revived approach remain undefined, it highlights how historical legal tools now shape advanced sanctions enforcement systems.

Curious if AIS signals get flagged the second a vessel is targeted for seizure—like how the Treasury Department marks specific tankers as subject to sanctions before any legal action kicks in. The process often starts with that designation, so it’s plausible they’d monitor AIS closely from that point onward.
Freight forwarders are absolutely drowning right now—especially when cargo gets stuck in limbo for weeks or months, with no clear answer on who’s picking up the tab. And it’s not just logistical headaches; the U.S. is now weaponizing old legal tricks to freeze Iranian oil shipments, using the sue-and-attach procedure under the Foreign Sovereign Immunities Act to seize assets tied to sanctions—just like they did with Confederate cotton in the 1860s, or more recently with Venezuelan and Russian oil. The Treasury designates the cargo, the courts freeze it, and suddenly, your clients’ shipments could be collateral in a diplomatic standoff—leaving everyone scrambling to cover the costs.
Brokers void insurance in hours once US courts step in. How does this affect the shipping rates? The process starts with the U.S. Treasury designating specific tankers, cargo titles, or shipping firms as subject to sanctions, which can trigger immediate insurance cancellations and put upward pressure on rates.
