U.S. Weighs Seizing Iran’s Kharg Island to Force Strait of Hormuz Reopening

U.S. officials are considering plans to occupy or blockade Kharg Island, a major hub for Iran's crude exports, as a means to compel Tehran to reopen the Strait of Hormuz. Multiple sources say the operation would follow further U.S. strikes to reduce Iranian military capacity and would require additional troop deployments beyond forces already en route.

Key Points

  • U.S. officials are considering occupying or blockading Kharg Island to compel Iran to reopen the Strait of Hormuz, based on information from four people familiar with the discussions.
  • Kharg Island, about 15 miles offshore, processes roughly 90% of Iran's crude exports, making any attack or occupation a major escalation with direct implications for global energy markets and shipping.
  • Officials say an operation would follow further U.S. strikes to weaken Iranian military capabilities near the strait and would require more troop deployments beyond three Marine units already headed to the region.

Overview

Senior U.S. officials are exploring an option to take control of or impose a blockade on Kharg Island in an effort to reopen the Strait of Hormuz, according to four sources familiar with the discussions. The report, which remains unconfirmed, rattled energy traders and prompted a swift market reaction tied to global oil flows.

Strategic importance of Kharg Island

Kharg Island sits about 15 miles offshore and serves as the terminal for roughly 90% of Iran's crude oil exports. Any direct military action against the island would represent a significant escalation in the standoff surrounding the Strait of Hormuz, a key maritime chokepoint through which a substantial share of world oil supplies transits.

Operational prerequisites

Officials say the contemplated operation would not be attempted immediately. Sources indicate it would be launched only after an additional phase of U.S. military strikes aimed at degrading Iranian military assets near the strait. One source estimated that about one month of such strikes would be necessary before an attempt to seize the island might proceed.

Force requirements and posture

Carrying out an occupation or blockade of Kharg would require forces beyond the three Marine units already reported to be en route to the region. A U.S. official told reporters that the White House and the Department of Defense are weighing further troop deployments to support the potential operation.

Administration stance

A senior administration official said the president wants the Strait of Hormuz reopened and is prepared to take Kharg Island or mount a coastal invasion if necessary. The official added that no final decision has been made.


Implications

The discussion of occupying or blockading an island that handles the majority of Iran's crude exports underscores the severity of options under consideration and the potential for heightened military and market disruption if those plans advance.

Risks

  • Military escalation - Carrying out strikes and attempting to seize Kharg Island would be a significant intensification of hostilities, posing risks to regional stability and defense-related sectors.
  • Energy market disruption - Targeting infrastructure that handles the bulk of Iran's crude exports could disrupt oil supplies and amplify volatility in energy markets and shipping.
  • Operational uncertainty - Officials say the plan depends on a prior campaign of strikes and additional troop deployments, creating uncertainty about timing, execution, and potential unintended consequences.
