Iran Scrambles to Store Surplus Oil as Sweeping US Sanctions Disrupt Exports

By Jian Yi, Vision Times

Growing U.S. pressure on Iran’s oil exports is beginning to show tangible effects, as storage capacity at key export hubs approaches its limits and Tehran scrambles to manage rising inventories. At the center of the strain is Kharg Island, which handles roughly 90 percent of Iran’s crude exports.

According to reporting cited by the New York Post, the island’s storage facilities are nearing full capacity amid continued disruptions to outbound shipments.

Additional reports also indicate that Iran is currently unable to export approximately one million barrels of oil per day, leading to a rapid accumulation of unsold crude. Analysts warn that, at the current pace, remaining storage space on Kharg Island could be exhausted within nearly two weeks. Should export constraints persist, the impact on Iran’s oil-dependent economy could be immediate and severe.

To relieve the growing backlog, Iranian authorities have reportedly turned to unconventional solutions. Among them is the reactivation of an aging tanker known as the Nasha, which had been inactive for decades. The vessel is being repurposed as a floating storage unit, effectively serving as a temporary offshore oil depot.

The use of floating storage is not new in the global oil market, countries and companies have relied on it during periods of oversupply or disrupted logistics, but it typically signals that conventional infrastructure is under strain. In Iran’s case, the move reflects limited onshore storage capacity at key export hubs such as Kharg Island, as well as reduced access to international buyers and shipping routes amid tightened sanctions enforcement.

Analysts say such measures are inherently short-term, as maintaining large volumes of crude at sea can be costly and operationally inefficient. The reliance on stopgap solutions underscores the mounting pressure on Tehran’s export system, where logistical bottlenecks are increasingly intersecting with geopolitical constraints.

US expands maritime pressure

Meanwhile, Washington appears to be increasing both economic and military pressure in tandem. In addition to efforts to intercept vessels suspected of transporting Iranian oil, the U.S. has reinforced its presence in the Middle East.

The deployment of the aircraft carrier USS George H.W. Bush to the region marks a further escalation in maritime oversight, particularly around the strategically critical Strait of Hormuz.Iran oil sanctions 2026, Kharg Island storage capacity, Iran crude exports blocked, floating storage tanker Nasha, USS George H.W.

The narrow waterway remains one of the world’s most vital energy corridors, and any disruption there carries global implications for oil markets.

Amid mounting pressure, U.S. officials have signaled that diplomatic options remain open, but may not remain so indefinitely. U.S. Defense Secretary Pete Hegseth stated that Iran still has an opportunity to resolve tensions through negotiations, but cautioned that “time is not on Iran’s side.”

U.S. President Donald Trump also issued a warning, saying that if Iranian leadership declines to engage in talks, Washington could consider additional measures, including potential military action.

Economic risks ahead

For Iran, the current situation highlights the vulnerability of its export-dependent energy sector under sustained external pressure. With limited storage capacity and restricted access to international markets, the country faces increasing difficulty managing supply flows.

If storage constraints are reached, Iran could be forced to reduce production, an outcome that would carry broader fiscal consequences given the central role of oil revenues in the national economy. At the same time, the reliance on temporary solutions such as floating storage suggests that Tehran is seeking to buy time while navigating both economic and geopolitical challenges.
