A tiny five-mile-long strip of land has up to 90 per cent of Iran’s oil pumping through it
By
Nestled within the waters of the northern Persian Gulf is a tiny, five-mile-long stretch of land known as Kharg Island. Despite its modest size, this piece of land serves as a pivotal terminal for nearly all of Iran’s oil exports – with a loading capacity of about seven million barrels per day.
At times, around 90 per cent of the nation’s oil exports have passed through Kharg. Pipelines connect the island to offshore oilfields in the Persian Gulf, as well as major oilfields on the Iranian mainland.
The result is a dense concentration of energy infrastructure that makes the island one of the most strategically sensitive points in the global oil network.
But what is Kharg’s history, and how did it become such a major oil site?

Iran’s oil export lifeline
Kharg first became strategically important back in the 1960s oil boom. After offshore oilfields were discovered in the Persian Gulf and southern Iran, the island was developed into a major crude-export terminal linked by pipelines to both offshore platforms and mainland oilfields in Khuzestan.
By the early 1970s, this infrastructure had transformed Kharg into Iran’s largest oil-loading terminal.
Energy analysts often describe the island as a single-point vulnerability: disrupting Kharg would immediately constrain Iran’s ability to sell crude to global markets, and also potentially hike up oil prices.
Kharg’s role in geopolitics
During conflicts in the Gulf, Kharg’s importance became especially clear. Throughout the Iran-Iraq War, Iraq repeatedly bombed Kharg’s oil infrastructure. Iraqi aircraft targeted the island throughout the 1980s, aiming to cripple Iran’s economy by ceasing its oil exports.
By 1986, much of the terminal infrastructure had been severely damaged or temporarily disabled. However, despite repeated air strikes, Iran was able to keep exporting oil from Kharg throughout the war.
After the war, Iran spent years repairing and expanding the facilities.
A long history
Prior to the arrival of oil on the island, Kharg had an important role in trade and maritime culture in the Persian Gulf.
According to medieval sources, the island was known to be a centre for pearl fishing and Gulf trade by the late 10th century. In the 17th century, travellers described the island as a trading stop connected to Basra, Bandar Rig and the Iranian interior.
Its prime location along shipping routes also made it a place where ships could hire experienced Gulf pilots to navigate the shallow waters near Basra.
Keeping an eye out
It may be thousands of kilometres away from the US, but that fact wouldn’t necessarily deter President Trump from sizing up Kharg.
According to a senior Pentagon adviser on Iran and Iraq in the George W. Bush administration, Michael Rubin, seizing Kharg Island would deprive the regime of a key funding source for controlling the population, in a way that would intensify pressure on Iran outside of missile strikes and bombings.
‘If they can’t sell their own oil, they can’t make payroll,’ said Rubin.
However, it’s unlikely that American or Israeli forces would intentionally damage Kharg, said senior fellow at the Atlantic Council Global Energy Center Ellen Wald. Wald argued that, ultimately, it could trigger a wave of Iranian retaliation against energy infrastructure across the region and drive up oil prices worldwide.
