Kharg Island: Iran’s Economic Lifeline and Strategic Asset

Recent U.S. Military strikes on Kharg Island, a small but strategically vital island off the coast of Iran, have thrust it into the global spotlight. This action underscores the island’s critical role in Iran’s economy and its importance in maintaining the free flow of oil through the Strait of Hormuz. The strikes, which targeted military facilities while intentionally avoiding oil infrastructure, represent a demonstration of leverage should Iran interfere with shipping lanes.

What is Kharg Island?

Kharg Island is located approximately 20 miles off Iran’s northern Gulf coast [1] and serves as Iran’s primary terminal for oil exports. Historically, the island has handled 85–95% of the country’s crude oil exports [1]. Tankers load crude oil on the island before transiting the Persian Gulf and the Strait of Hormuz. Disrupting operations at Kharg Island would severely cripple Iran’s ability to export oil, a crucial source of revenue, particularly from sales to China [1].

Strategic Importance and Potential Escalation

The U.S. Strikes on Kharg Island, while avoiding oil infrastructure, were a clear signal of intent. President Trump warned that any interference with the safe passage of ships through the Strait of Hormuz could lead to a reconsideration of this restraint [1], [2]. Such a move would represent a significant escalation, potentially sending shockwaves through global oil markets. Iran has responded by threatening to target oil infrastructure associated with U.S. Allies should its own facilities be attacked [2].

Economic Lifeline for Iran

Kharg Island is a small rocky outcrop, only 15 nautical miles (24km) off the Iranian coast [2]. Despite its size, it is a critical component of Iran’s energy infrastructure. Approximately 90% of Iran’s crude oil passes through a terminal on the island via pipelines from the mainland [2]. Very large tankers, capable of carrying up to 85 million gallons of oil, utilize the island’s jetties for loading. The island’s proximity to deep waters, unlike the shallower mainland coast, facilitates this process.

Funding the Government and Military

According to Petras Katinas, an energy researcher at the Royal United Services Institute, Kharg Island is critical to funding both the Iranian government and its military [3]. Iran has exported 13.7 million barrels of oil since the start of the recent conflict, with tankers frequently observed loading at Kharg Island [3]. A strike on Kharg Island would not only impact the current Iranian government but could also jeopardize the stability of any future regime.

The Strait of Hormuz Connection

Approximately 20% of the world’s oil supply passes through the Strait of Hormuz [1], making it a vital chokepoint for global energy security. The U.S. Strikes on Kharg Island demonstrate the ability to impact Iran’s energy system, providing leverage in negotiations regarding the safe passage of ships through the Strait [1].

The island also provides a major source of revenue for the Islamic Revolutionary Guard Corps (IRGC) [2].
