Trump threat to Iran oil hub jolts crude prices

On June 11, 2026, President Donald Trump said on Truth Social that the United States would "at some point in the not too distant future" take Kharg Island and other Iranian oil infrastructure points. He added that the U.S. military would hit Iran "VERY HARD TONIGHT," tying the threat to ongoing military action.

The comments followed fresh U.S. strikes on Iranian military targets in early June 2026, marking a new phase of escalation. Trump framed the prospective move as part of a broader effort to assume control of Iran’s oil and gas markets.

Later in the day, during a Fox News interview, Trump appeared to temper the threat, saying he was not sure the United States "has the stomach" for a protracted operation to seize Kharg Island. The remark introduced uncertainty over how far the administration is prepared to go militarily.

Kharg Island is Iran’s principal crude export terminal, handling about 90% of the country’s crude oil exports. Its role makes it a central node in Iran’s energy revenues and a critical focus in any attempt to pressure Tehran through its oil sector.

U.S. defence officials and analysts say that plans to seize Kharg Island have been drawn up but repeatedly shelved. They assess that such an operation would require significant ground forces, be high-risk and could incur heavy U.S. casualties.

Previous U.S. strikes on Kharg have focused on military sites while deliberately avoiding the island’s energy infrastructure. This pattern underscores the sensitivity around disrupting Iran’s export capacity outright, even amid heightened hostilities.

The latest threats and strikes fed directly into oil market pricing on June 11. U.S. crude futures (USOIL) traded around $90 per barrel, while Brent crude (UKOIL) hovered near $93 per barrel as the session progressed.

Intraday, Brent (UKOIL) moved between gains and losses around the $93 mark, while U.S. crude futures (USOIL) were recently quoted at $90.38 per barrel and Brent at $93.08. The price action reflected investors weighing the risk of supply disruption against intermittent signs of restraint.

Market participants focused on potential disruption to shipping in the Strait of Hormuz and on renewed U.S.–Iran hostilities. At the same time, officials stated that commercial ships continued to transit the strait, signaling that flows had not been choked off.

The contrast between Trump’s threat to seize Kharg Island and his later doubts about whether the U.S. "has the stomach" for such an operation highlights a tension between rhetorical pressure and operational risk. Military planners have treated a direct attempt to capture the terminal as a high-cost option.

For energy markets, Kharg’s role in handling about 90% of Iran’s crude exports means any credible move against the island could have significant implications for global supply. For now, traders appear to be pricing in elevated risk premia without a complete breakdown in Gulf shipping.
