Introduction

• Kharg Island is a small island of Iran in the northern Persian Gulf.
• It is extremely important because it serves as the main terminal for Iran’s oil exports.

• Kharg Island is located in Iran, in the northern Persian Gulf.
• It lies about 55 km northwest of Bushehr, according to Britannica.

• Britannica describes Kharg Island as a small coral island.
• It is one of the relatively few islands in the Persian Gulf with natural freshwater resources, which helped support settlement.

Why it is important

• Kharg Island is important mainly because it is Iran’s principal oil export hub.
• Britannica states that it serves as the terminal for nearly all of Iran’s oil exports.

Oil export significance

• The island has a very large oil-loading role. Britannica notes that it has a loading capacity of about 7 million barrels per day and can load 10 supertankers simultaneously.
• U.S. energy analysis also identifies Kharg, along with Lavan and Sirri, as one of the key island terminals handling almost all of Iran’s crude oil exports.

Strategic significance

• Kharg Island is strategically important because any disruption there can affect:
  • Iran’s export earnings
  • regional Gulf security
  • global oil prices
  • wider energy supply chains.
    This follows directly from its role as Iran’s main export terminal.

Historical relevance

• Kharg Island has also been important historically in conflicts involving Iran’s oil infrastructure.
• Britannica’s Tanker War entry notes that Iraqi attacks around Kharg Island were part of the wider Gulf conflict during the Iran-Iraq War.

Geographic advantage

• A key reason for Kharg’s oil importance is its surrounding deep water, which allows long jetties and access for very large tankers more easily than much of Iran’s shallower coastline. This is described in standard reference material on the island.

Current relevance

• Kharg Island remains highly relevant in current affairs because it continues to be central to Iran’s oil exports amid heightened regional tensions in 2026. Reuters reported in March 2026 that it handled around 90% of Iran’s oil shipments and that any strike on it could sharply affect world oil markets.
• Recent reporting has also shown that oil flows from Iranian facilities, particularly Kharg Island, remained a major focus during U.S.–Iran tensions in April 2026.
• Kharg Island is a small but highly strategic island in the Persian Gulf. Its significance comes not from size, but from the fact that it is the core hub of Iran’s oil-export system and therefore a major point in Gulf geopolitics and global energy security.
