# U.S. to Receive $600M in Seized Iranian Oil, Reviving Ancient Maritime Law Three Iranian tankers carrying seized crude head to Texas under medieval prize law. - **Source:** [Fortune](https://fortune.com) - **Published:** 2026-09-27 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/0579a3a3-f321-4621-90c6-a263a41ecca4 ## Seized tankers en route Three VLCCs (Tifani, Majestic X, Lenore/Davina) carrying 6M barrels of Iranian crude are crossing the Atlantic toward Texas. Seized under Trump's April blockade, they represent $600M in oil at current Brent prices. The vessels were intercepted in the Indian Ocean between April-June under expanded powers targeting Iran-linked ships globally. ## Blockade strategy shifts The U.S. naval blockade initially barred ships from Iranian ports, then expanded to any Iran-linked vessels worldwide. After a brief summer ceasefire, Trump reinstated it as part of economic warfare tactics. Unlike typical sanctions, this approach physically controls commodity flows using naval interdiction. ## Medieval legal mechanism The seizures employ 'prize law' - a 13th-century maritime doctrine allowing wartime confiscation of enemy assets without warrants or statutory violations. Codified in the U.S. Constitution's Captures Clause, it bypasses civil forfeiture requirements. Last used during the 1898 Spanish-American War, this marks its 21st-century revival. ## Texas legal preparations The Southern District of Texas' U.S. Attorney's office confirmed readiness to adjudicate the seizures. Houston-based refiners could process the crude if courts approve forfeiture. Prosecutor Aaron Reitz cited national security needs but didn't specify whether using the 1812 Prize Act or Captures Clause for legal basis. ## Strategic oil interception Each VLCC carries 2M barrels - significant volume given current $106/bbl Brent prices. The operation demonstrates U.S. capability to physically disrupt Iran's oil exports beyond financial sanctions. Unlike previous measures, this directly removes product from global markets rather than just deterring buyers. ## Historical precedent Lincoln used the 1812 Prize Act against Confederate ports. The current application against a nation-state (vs. non-state actors) sets new precedent. Legal scholars note this tests boundaries between economic warfare and traditional naval blockades in modern contexts where formal war declarations are rare. ## Enforcement implications The Defense Department's direct seizure authority under prize law bypasses Coast Guard protocols. This expands military's economic warfare role beyond traditional combat functions. The move may prompt other nations to review historical maritime laws for contemporary economic conflicts. ## Global energy calculus Successful forfeiture would remove Iranian crude from markets while boosting U.S. strategic reserves. However, it risks normalizing extrajudicial commodity seizures in international waters. The episode highlights how ancient legal frameworks can resurge to address modern geopolitical-economic tensions. ## Sources covering this story - https://fortune.com/2026/09/27/us-600-million-iranian-oil-seizure-naval-blockade-prize-law/ — --- _Summary written by Brifing from the original reporting.
