US sanctions waiver unlocks $9 billion in stranded Iranian crude

The US temporary sanctions waiver on Iranian oil could unlock as much as $9 billion in stranded crude, reshaping global supply flows and deepening the rout in Brent crude that has already lost 16% this month.

"Production, sales, dollar payments, petrochemicals and protected shipping — all switched on at once," said Miad Maleki, a former Treasury sanctions official and senior fellow at the Foundation for Defense of Democracies. "Together, they amount to a sustained reopening of Iran's most important revenue stream."

The Treasury's General License X, issued Monday, authorizes dollar-denominated trade in Iranian crude, petroleum products and petrochemicals through Aug. 21 — the first such exemption since the 1979 Islamic Revolution. Ship-tracking firm Vortexa estimates Iranian crude on water at 126 million barrels, with about half already floating in Asian waters and another 67 million barrels stranded in the Gulf. Iran shipped 6.79 million barrels last week, the highest in two months, according to maritime intelligence firm Windward.

The waiver hands Tehran a potential windfall of $8 billion to $9 billion, according to Maleki, while pressuring other Gulf producers. Middlemen have already begun offering discounted Iranian crude to Indian refiners, though most Asian buyers say they are covered through August. China, which purchases roughly 90% of Iran's oil exports, remains the likeliest destination for the bulk of the new supply.

The timing of the waiver caught many Asian refiners off guard. Indian, Japanese and South Korean buyers — which last purchased Iranian crude nearly a decade ago — said they had already secured cargoes through August after scrambling to replace supplies disrupted by the Strait of Hormuz blockade since March. Three Asian refining sources told Reuters they face compliance hurdles and tight timelines, with Japanese buyers noting they would need trial runs before resuming purchases.

"The biggest beneficiary of any sanctions waiver on Iranian oil would likely be China, which needs crude for both processing and strategic stock replenishment," said Sumit Ritolia, lead analyst at ship-tracking firm Kpler.

Iran Ramps Up Exports

Iranian crude on water has increased by 6 million barrels over the past 48 hours alone, Vortexa data show, as Tehran moves to capitalize on the window. The National Iranian Oil Co. has sought proposals from Asian refiners and is calculating delivered prices of rival crudes to China for possible spot sales, according to industry sources.

Chinese independent refiners, known as teapots, have been the primary buyers of Iranian oil in recent years, accounting for the bulk of China's roughly 90% share of Iranian exports. Their appetite is currently weak after output cuts since May, but analysts expect a rapid pickup as buyers rush to replenish stockpiles before the exemption expires.

"With dollar clearing now authorized, expect China to accelerate purchases aggressively," Maleki said.

Global Prices Under Pressure

The return of Iranian supply is compounding downward pressure on global crude benchmarks. Brent crude has declined about 16% so far in June, and traders expect Iranian oil — typically priced at a discount to global benchmarks — to widen spreads on Russian grades and push Saudi Arabia and other Gulf producers to lower official selling prices to defend market share.

Still, deterrents remain for companies looking to resume Iranian oil imports. Indian refiners said they are unwilling to commit to purchases unless sanctions relief is assured beyond August. Banking and payment systems remain a stumbling block for fuel oil and bunker trade, even with the waiver in place.

President Donald Trump defended the lifting of sanctions, saying Monday that any oil profits were meant for Iran to purchase American agricultural goods rather than rebuild its military. Talks in Switzerland toward a final peace deal continue, with Vice President JD Vance leading negotiations.
