Global crude discounts hit 6-year lows as Iran sanctions ease

Washington's 60-day waiver on Iranian oil sanctions has unleashed a wave of Middle Eastern supply, sending Dubai crude to a 27-cent discount from a $60-plus March premium and forcing Atlantic Basin grades to multi-year lows.

"The political rhetoric suggests Iran just won the lottery. The reality is far less dramatic," Brett Erickson, managing principal at Obsidian Risk Advisors, said. "Tehran was already selling oil; it was simply paying a sanctions tax in the form of discounts, shadow shipping and financial laundering costs."

Cash Dubai slipped to a 27-cent discount Tuesday after peaking above $60 in March, while Oman and Murban discounts widened to 96 cents and 67 cents, respectively, Reuters data shows. North Sea Forties crude traded at a $1 discount to dated Brent, down from a record $21.50 premium in April. Congolese Djeno assessed at a $10.80 discount — the lowest in records dating to 2013 — and Angola's Nemba at an eight-year low of $8. Abu Dhabi National Oil Co. sold at least 48 million barrels of spot crude this month for June-August loading, boosting regional supply.

The supply surge threatens to depress crude prices further as Iran ramps up exports beyond China for the first time in years. Under the Treasury's General License X, Iran could earn an additional $1.5 billion over the 60-day window compared with what it would have under sanctions, according to Erickson's estimates. The real test comes after Aug. 21, when the waiver expires and negotiations toward a permanent deal continue.

Tanker Rates Surge as Stuck Cargoes Move

Very large crude carrier rates for Gulf cargoes transiting the Strait of Hormuz jumped to a record of nearly $470,000 a day, more than quadruple the pre-conflict average, as about 100 tankers stranded inside the Gulf since February begin moving cargoes. Rates for vessels hired outside the strait rose to $190,500 a day from $106,500 a week ago, according to ship brokers. War risk insurance premiums have softened to about 3 percent of vessel value from 5 percent a week ago, though traffic through the strait remains a fraction of the pre-conflict daily average of 125 ships.

Iran, which had been producing about 2.3 million barrels a day with only 200,000 barrels available for export, could ramp up to 500,000 export-ready barrels per day, Erickson said. The country has about 180 million barrels in storage and at sea, with 95 million outside the former US blockade line in the Persian Gulf. At an $11-per-barrel realized revenue gain from the waiver — combining a roughly $5 price premium and $7 in avoided shadow fleet costs — Iran could earn about $1.5 billion more than under sanctions over the 60-day window, Erickson calculated.

Ben Cahill, nonresident senior fellow at the Atlantic Council Global Energy Center, said the key question is whether Iran can sell more oil outside China. "Buyers elsewhere now have a green light to buy Iranian oil and to pay in US dollars, but it takes time to arrange deals, financing and all the logistical and payment details," he said. If the waiver becomes permanent, Cahill estimates Iran could earn an additional $35 billion annually in oil revenue.

The collapse in Middle Eastern crude prices has opened arbitrage to Europe, with Exxon Mobil, Eni and TotalEnergies sending supertankers of Abu Dhabi's Murban and Upper Zakum grades to European refineries. Conversely, weak Middle East prices have shut the arbitrage window for Atlantic Basin crude to Asia, with US West Texas Intermediate Midland flipping to a 45-cent discount from a premium a week ago. US crude exports to Asia are set to ease in the third quarter after hitting a record 2.634 million barrels per day in May, Kpler data shows. Asian refiners, which typically buy crude two months in advance, have already booked cargoes for delivery through August and have little need for incremental barrels, Sparta Commodities analyst June Goh said.

For the global oil market, the waiver represents a structural shift: Iran's return as a legitimate seller could add 500,000 barrels per day or more to export flows, potentially keeping Brent anchored below $70 as long as the diplomatic track holds.
