Trump Vows US Will Seize Iran's Kharg Island Oil Terminal

President Donald Trump told reporters in the Oval Office on Wednesday that the United States “will be taking” Iran’s Kharg Island, the offshore terminal in the northern Persian Gulf that handles the overwhelming majority of Iranian crude exports, a sharp escalation from his warning earlier today that Washington was prepared to hit Iran’s oil sector if the fragile ceasefire continued to fray. The remarks, reported by Al Jazeera and Defense News, drew an immediate rejection from Tehran and sent oil markets and shipping insurers scrambling for clarification from the White House.

What Trump said

Asked about the next phase of US action against Iran, Trump said the United States “will be taking” Kharg Island, calling the terminal “the linchpin” of the Iranian oil trade. He did not specify a timeline, force package, or whether “taking” referred to a physical seizure, a blockade, or strikes designed to render the loading infrastructure inoperable. White House staff did not clarify the remarks before this article was filed. Defense News described Kharg as having “once more come under focus amid a fraying ceasefire,” noting that the island has been a target of Western planning since the tanker wars of the 1980s.

Iranian officials, quoted by Al Jazeera, called any move on Kharg an act of war that would draw a response “against every American asset in the region.” Tehran has previously linked any direct US action against its oil export infrastructure to a full closure of the Strait of Hormuz, a step it began executing yesterday when IRGC fast boats fired on commercial shipping in the strait.

What Kharg Island is

Kharg is a roughly 8-square-mile island about 25 kilometers off Iran’s southwestern coast in the northern Persian Gulf. Its T-jetty and Sea Island loading platforms can berth multiple very large crude carriers at once, and MarketWatch reported that the terminal handles approximately 90% of Iranian crude exports. Pipelines from the Khuzestan and offshore fields feed storage tanks on the island, which then load tankers bound mainly for Chinese refineries.

The terminal has been struck before. Iraqi aircraft hit Kharg repeatedly during the 1980–1988 Iran–Iraq War, and Iran rebuilt and hardened the facility afterward. It is defended by air-defense batteries, IRGC Navy fast boats, and shore-based anti-ship missiles, and it sits within the engagement envelope of Iranian land-based aviation operating from Bushehr and Bandar Abbas.

The military reality

A physical seizure, MarketWatch noted, would require an amphibious or air-assault operation against a defended island roughly 1,200 kilometers from the nearest US ground-force concentration in the Gulf, with sustained air superiority over the northern Persian Gulf and a logistics tail capable of holding the terminal under continuous Iranian fire. The outlet observed that strikes designed to disable loading infrastructure, rather than occupy the island, are a lower-cost option and one the United States has rehearsed in past planning cycles.

US legal authority for a seizure is contested. MarketWatch cited scholars who noted that neither the 2001 nor the 2002 Authorizations for Use of Military Force cover an offensive operation against Iran, and that a sustained action against Kharg would likely trigger the same War Powers Resolution clock that Congress has already debated this spring. The White House has not indicated which legal basis it would invoke.

For shipping, the implications are immediate. Insurance underwriters have already widened war-risk premiums for Gulf transits after this week’s strikes, and a credible threat to Kharg would likely push tanker rates and Brent higher when Asian markets open Thursday. Markets had been pricing in de-escalation earlier in the session before the Trump remarks crossed the wires.

The wider market backdrop

The World Bank on Wednesday cut its 2026 global growth forecast to 2.5%, the slowest pace since the pandemic, citing the Iran war and the associated energy shock as the principal drag on global activity. OPEC production, separately, fell to its lowest level since 2000, reflecting both voluntary Saudi cuts and the loss of Iranian barrels from the legal export market.

Tracking data reviewed by OilPrice indicates another Gulf producer has joined the dark-mode tanker traffic moving through the Strait of Hormuz with AIS transponders disabled, a pattern previously associated with sanctioned Iranian and Russian cargoes that now extends to ostensibly compliant producers seeking to avoid being identified by Iranian forces operating in the strait.

The tanker strikes off Oman

The Kharg threat comes against the backdrop of a third US strike this week on a tanker in the Gulf of Oman. The Pentagon confirmed it had disabled the vessel, which it accused of carrying sanctioned Iranian crude. The BBC reported that three Indian sailors aboard the tanker were killed in the action. New Delhi has requested a formal accounting from Washington; the State Department has not yet commented publicly. The Pentagon’s interdiction campaign in the Gulf of Oman, paired with Monday’s restart of strikes on key Iranian facilities, represents the most sustained US use of force against Iranian-linked shipping since the 1988 Operation Praying Mantis engagements.

What to watch

• A White House clarification of whether “taking” Kharg means seizure, blockade, or strikes on loading infrastructure.
• Iranian deployment of additional air-defense and anti-ship batteries to Kharg and the surrounding coastline.
• Whether Lloyd’s and other London war-risk underwriters issue a new northern Persian Gulf advisory tonight.
• Brent and WTI when Asian markets open Thursday; the threat lands after the New York close.
• Statements from New Delhi on the deaths of the three Indian sailors and any related coordination with Washington.
• Any movement of US amphibious shipping or carrier assets toward the northern Gulf in the next 48 hours.

Standing watch.
