Strategic Significance of Iran's Larak and Kharg Islands Amid Escalating US Tensions

Recent attacks by the US on Larak Island and threats from President Donald Trump regarding Kharg Island have significantly re-escalated the ongoing conflict. According to US forces, the strike on Larak Island occurred as Iran's Islamic Revolutionary Guard Corps was preparing to launch rockets carrying sea mines into the Strait of Hormuz. The US military recently announced it successfully removed or detonated all mines in the strait to ensure safe passage for commercial shipping through the vital waterway.

Larak Island functions as a key naval and logistics base for the IRGC, as well as a secondary oil storage and transfer hub. The military value of the island is primarily geographic, as it overlooks the Strait of Hormuz and has been used by Iran to station naval assets such as fast boats, missile systems, and sea-mine infrastructure.

Meanwhile, tensions have further mounted around Kharg Island following a direct threat issued by Mr Trump on Truth Social, which included an AI-generated video depicting a massive explosion. An attack on Kharg Island would carry severe economic consequences, given that it serves as Iran's primary oil export hub. The facility manages approximately 90 per cent of the country's crude exports, boasting a loading capacity of seven million barrels per day and a storage capacity of 30 million barrels. Prior to the conflict, the vast majority of these shipments—about 80 per cent—were directed to Asian customers, particularly China.

Crude oil from major onshore oilfields such as Ahvaz, Gachsaran, and Agha Jari travels through undersea pipelines located roughly 30 kilometres off the coast of Iran to reach the island for tanker loading. The infrastructure includes extensive offshore loading platforms, storage tanks, and deepwater berths capable of accommodating very large crude carriers.

Noureldeen Al Hammoury, chief market strategist at Equiti Group, noted that any sustained damage to Kharg Island would effectively halt Iranian crude exports, which are currently estimated at 1.5 million to 1.8 million barrels per day, representing a substantial portion of global supply. Following these developments, global oil markets reacted as Brent benchmark prices surged by as much as 3 per cent to exceed $90 per barrel.

This escalation follows the implementation of new economic sanctions by Washington aimed at isolating Iran's economy. Under Operation Economic Outcast, announced by the US Treasury Department, secondary sanctions have been broadened to target countries and companies conducting business with Iran, setting a strict deadline for them to terminate all related activities. According to the US Energy Information Administration, Iran held the world's third-largest oil and second-largest natural gas reserves in 2023, accounting for 24 per cent of Middle Eastern oil reserves and 12 per cent of the global total, despite production limitations caused by long-standing international sanctions and underinvestment.
