The United States is actively considering the seizure of oil tankers carrying Iranian crude as a new phase of pressure on Tehran to constrain its nuclear program, according to a Wall Street Journal report citing American officials. This potential escalation is part of a broader campaign to restrict Iran’s oil revenue and force a diplomatic breakthrough on nuclear limits.
The proposal follows recent actions where the U.S. has already detained vessels transporting Iranian oil, targeting what officials describe as a clandestine “shadow fleet” used to evade sanctions. These ships are allegedly employed to move crude from heavily sanctioned nations like Iran and Venezuela to buyers in China and elsewhere. While senior officials in the Trump administration have debated directly confiscating Iranian vessels, they have hesitated due to concerns about possible retaliation from Tehran and destabilizing global oil markets.
The option of vessel seizures is one of several measures under White House discussion to push Iran toward accepting strict restrictions on its uranium enrichment. U.S. officials note significant legal and operational hurdles to such seizures. Iran has repeatedly warned that any intensified U.S. enforcement could prompt it to seize oil tankers from U.S. allies in the region, an action that might trigger a sharp spike in global oil prices and create political challenges for the White House.
This year, the U.S. Treasury Department has sanctioned over 20 vessels suspected of involvement in the Iranian oil trade, potentially identifying targets for future seizure. A White House official, when queried about boarding such tankers, stated that President Trump prefers diplomacy but retains a range of options should negotiations fail.
The consideration of direct seizures occurs against a backdrop of heightened military tension, with the U.S. recently reinforcing its naval and air presence in the Middle East. Washington demands Iran accept a “zero enrichment” policy for its nuclear program and has not ruled out military action. Iran maintains its enrichment activities are a legal right under the nuclear Non-Proliferation Treaty, framing them as an issue of national sovereignty.
Iranian Foreign Minister Abbas Araghchi, in an interview this week, expressed Tehran’s commitment to a diplomatic resolution while preparing for the risk of renewed conflict. “There is no solution but a diplomatic solution,” he stated, arguing that military threats cannot dismantle a nation’s technological progress. The U.S. strategy of economic pressure via oil shipments thus intersects with high-stakes diplomacy, where the potential for miscalculation carries significant regional and economic consequences. The next steps will likely depend on the trajectory of indirect talks and Iran’s response to the escalating financial pressures.
