Iran's Idle Crude Oil Storage Reduced to Below 22 Days
According to Bloomberg, based on Kpler data, Iran's idle crude oil storage is now only 12 to 22 days.
Due to a 70% drop in exports caused by the U.S. Navy blockade, Iran is rapidly depleting its storage capacity and may be forced to further cut production, having already reduced output by 2.5 million barrels per day.
Market mechanisms show that the inability to export Iranian crude has led to domestic inventory buildup, with buyers shifting their funds to alternative suppliers like Saudi Arabia and Iraq. Tanker operators and other oil-producing countries in the Middle East benefit, while Iranian oilfield operators and related export industries face pressure. The global crude oil supply is at risk of short-term disruption, driving price volatility.

Iran has previously faced storage pressures due to sanctions and conflicts, especially at Kharg Island, its main export hub with a storage capacity of about 20-30 million barrels. The latest Kpler report indicates that utilization has exceeded 60%, continuing a historical pattern of forced well shut-ins due to export disruptions.
In terms of capital pathways, Iran is using limited tanker resources to circumvent blockades, but most crude oil is forced to be stockpiled on-site. Resources are shifting from export revenue to emergency use of abandoned tanks and rail transport attempts, with a strategy aimed at delaying until negotiations resume while avoiding irreversible damage to oil fields from permanent shut-ins.
Similar cases include the forced offshore floating storage during the peak of sanctions in 2018-2019 and the crude oil backlog in Russia due to sanctions in 2022. Currently, Iran's oil industry is at a critical stage of transitioning from export-led to forced production cuts and inventory crises.
Essentially, this represents a restructuring of the supply chain: geopolitical blockades sever export channels, forcing upstream production to match downstream transport bottlenecks. The mechanism is based on the physical property that crude oil cannot be stored at low costs for long periods, shifting pricing power from Iranian production to global alternative suppliers and buyers, while accelerating the diversification of the Middle Eastern energy supply chain away from reliance on Iran.
