Why Kharg Island matters in the Middle East and global oil markets

Kharg Island, a small coral outcrop in the Persian Gulf about 25 kilometers off Iran's coast, is a central hub for Iran's oil exports and a focal point in regional security calculations.

Roughly one-third the size of Manhattan, the island is often described as the "economic lifeblood" of the Iranian state. A 1984 CIA document called the facilities on the island "the most vital in Iran's oil system, and their continued operation is essential to Iran's economic well-being."

Economic importance

Kharg Island handles roughly 90% of Iran's crude oil exports, serving as the primary terminal for barrels pumped daily from major Iranian oil fields such as Ahvaz, Marun, and Gachsaran. Iran accounts for approximately 4.5% of the world's oil supply, meaning any disruption to Kharg's operations could have significant effects on global oil prices, says CNN.

The island's storage capacity is estimated at 30 million barrels, with around 18 million barrels currently stored. This makes it a key facility not only for export but also for managing Iran's domestic and international oil flows. Israeli opposition leader Yair Lapid has stated that destroying the oil terminal would "cripple Iran's economy and topple the regime."

Strategic and military significance

The island is heavily fortified and often referred to by Iranians as the "Forbidden Island." It has deep-water jetties capable of accommodating large oil supertankers and hosts substantial military assets. Recent US military strikes targeted military installations on Kharg Island, such as airport facilities and missile storage, while deliberately avoiding oil infrastructure. Former US President Donald Trump described these strikes as "one of the most powerful bombing raids in the history of the Middle East."

Former US Army Brigadier General Mark Kimmitt noted that the US is trying to "take out the economic lifeblood of this country," and is "holding the island 'hostage'" to ensure the Strait of Hormuz remains open. The threat of targeting Kharg's oil facilities also serves as leverage to prevent Iran from blocking this critical waterway.

Consequences of disruption

Experts and political leaders have warned that destroying the Kharg terminal would have far-reaching consequences. Lapid emphasized the economic and political impact, while the Islamic Revolutionary Guard Corps (IRGC) has threatened to set the region's oil and gas infrastructure "on fire" if Iranian energy sites are attacked.

Analysts note that rebuilding the facilities would be challenging due to ongoing Western sanctions. Senior crude oil analyst Muyu Xu said that "it would be difficult for them [Iran] to rebuild" if the oil facilities were destroyed. Kimmitt also warned that if regional infrastructure is attacked, "the prices of oil will just go out of control."

Key factors driving potential disruption include:

• Massive supply impact: Kharg handles approximately 90% of Iran's crude exports, removing millions of barrels from the global market if disrupted.
• Regional retaliation: Iran has publicly stated it will target oil facilities belonging to US allies in response.
• Strait of Hormuz stability: The island's safety is central to US leverage over the waterway, a critical conduit for global energy flows.
• Prolonged recovery: Sanctions would make restoring the facilities a long-term challenge, extending the supply reduction.
• Impact on major buyers: China, as Iran's primary oil customer, would likely face immediate economic consequences.

While US strikes have focused strictly on military targets to avoid global economic disruption, Kharg Island remains a strategic economic and military hub whose significance extends well beyond Iran's borders.
