Common Questions

What is General License U?: A US Treasury waiver issued 20 March 2026 authorising sale and delivery of Iranian crude oil loaded on vessels before that date. It expires 19 April 2026 and is the first OFAC licence ever to broadly authorise Iranian-origin crude transactions.Source: background
Will General License U be renewed?: No. Treasury Secretary Scott Bessent confirmed on 15 April 2026 that GL-U will not be renewed when it expires at 12:01am EDT on 19 April. He framed secondary sanctions on Iranian oil buyers as the financial equivalent of US bombing. Brent Crude fell on the announcement.Source: US Treasury
How many oil tankers are stranded because of Hormuz?: As of early April 2026, 325 oil tankers remain stranded inside the Persian Gulf, none transiting the Strait of Hormuz while it stays effectively closed. An additional 600-plus vessels of other types are also stranded.Source: Lowdown
Who can buy Iranian oil under General License U?: In practice, primarily Reliance Industries in India. GL-U authorises the commodity transaction but not banking, so only buyers with existing payment settlement workarounds can execute. The first confirmed delivery was 600,000 barrels from Kharg Island to Vadinar, India.Source: background

Background

US Treasury's Office of Foreign Assets Control issued General License U on 20 March 2026, authorising the purchase, transport, and delivery of Iranian crude oil and petroleum products loaded on vessels on or before that date. It is the first OFAC general licence ever to broadly authorise transactions involving Iranian-origin crude. The licence expires at 12:01am EDT on 19 April 2026. On 15 April, Treasury Secretary Scott Bessent explicitly confirmed non-renewal, pairing the announcement with a secondary-sanctions threat he described as "the financial equivalent of the US military's bombing campaign against Iran". Markets did not reprice: Brent crude fell on the confirmation. OFAC had issued zero Iran-specific actions in the 23 days between issuing GL-U and Bessent's statement, while amending Russia and Venezuela licences in the same window.

The practical effect was to allow existing cargoes in transit to reach buyers without triggering secondary sanctions. The first confirmed delivery under GL-U was the Aframax tanker PING SHUN, which delivered 600,000 barrels from Kharg Island to Vadinar, India, purchased by Reliance Industries, the first Iranian crude delivery to India since May 2019. GL-U does not authorise banking transactions, so in practice only buyers with existing settlement workarounds can execute under it.

GL-U's expiry creates a hard sanctions cliff three days before the Ceasefire window closes on 22 April. 325 oil tankers remain stranded inside the Persian Gulf and Hormuz as of early April, none transiting while the strait stays effectively closed. Non-renewal recriminalises all Iranian oil deliveries in transit, sharpening pressure on Tehran at a critical moment while simultaneously deepening the oil supply shock in markets already absorbing Hormuz's closure.

How the World Sees Them

Iran

A marginal concession; Tehran framed its demands as requiring full sanctions removal, not a one-month waiver on past shipments. GL-U's narrow scope and imminent expiry are viewed in Tehran as signalling no sustained sanctions relief.

India

Allowed Reliance Industries to receive the first Iranian crude delivery since 2019, testing appetite for resumed imports if sanctions ease further. Banking restrictions mean most Indian refiners cannot follow Reliance's model.

Oil markets

Hormuz closure is the dominant price driver; GL-U signals possible relief but has not moved prices. Its expiry without renewal would remove the legal basis for 325 stranded tankers and deepen the supply shock.

United States

A calibrated pressure valve: demonstrates sanctions flexibility without permanent relief, with the 19 April expiry as an implied negotiating deadline three days before the ceasefire window closes.
