US Treasury Secretary Bessent says Kharg Island is nearing storage capacity, costing Iran around $170mn per day in lost revenue and risking permanent damage to its oil infrastructure.
Summary:
- Treasury Secretary Scott Bessent said Kharg Island, Iran’s primary oil export terminal, is approaching storage capacity
- He warned this will force Iran to reduce oil production, resulting in roughly $170 million per day in lost revenue
- Bessent said the situation risks causing permanent damage to Iran’s oil infrastructure
- The Treasury has further sanctioned much of Iran’s shadow fleet of tankers used to circumvent existing restrictions
- Washington has threatened to cut off from the US banking system any country or company that continues to buy Iranian oil
- The remarks appear to be deliberate public messaging rather than breaking developments, designed to reinforce economic pressure on Tehran amid ongoing nuclear negotiations
US Treasury Secretary Scott Bessent has issued a pointed public warning about the deteriorating situation at Kharg Island, Iran’s principal oil export terminal, in what appears to be a calculated piece of economic pressure messaging from Washington rather than a disclosure of new developments.
Bessent said the island, which handles the overwhelming majority of Iran’s crude exports, is approaching storage capacity. When that limit is reached, he argued, Tehran will have no choice but to cut production, a move he said would cost the regime approximately $170 million per day in lost revenue. He added that the situation risks inflicting permanent damage on Iran’s oil infrastructure, a longer-term consequence that would outlast any near-term diplomatic resolution.
The Treasury has also moved to tighten the financial noose around Iran’s export network, sanctioning a significant portion of the shadow fleet of tankers that Tehran has relied upon to move oil to buyers willing to circumvent Western restrictions. Crucially, Bessent warned that any country or company continuing to purchase Iranian crude risks being cut off from the US banking system, a threat directed primarily at Asian refiners that have kept Iranian export volumes from collapsing entirely.
The remarks are framed as targeting the financial heart of the Iranian government, with oil revenues long serving as the primary funding mechanism for the regime’s budget and its broader regional activities.
The timing and tone of the statement suggest it is as much about signalling resolve as it is about revealing new intelligence. With nuclear negotiations ongoing and oil markets already on edge over Middle East supply risks, Washington appears to be using the Kharg Island situation to reinforce the message that the economic cost to Tehran is compounding, and that the window for a deal may be narrowing alongside Iran’s export capacity.

The $170 million per day revenue loss figure, if sustained, would accelerate pressure on Tehran’s finances. The threat to cut off any country or company buying Iranian oil from the US banking system is a significant escalation in secondary sanctions pressure, aimed squarely at the buyers, particularly in Asia, that have kept Iranian exports flowing. That threat alone could prompt some refiners to reduce Iranian purchases, further tightening supply
