Background

General License U was an Office of Foreign Assets Control general licence issued on 20 March 2026. It authorised the purchase, transport and delivery of Iranian-origin crude oil and petroleum products loaded on vessels by that date. Its narrow scope made it a wind-down measure for cargoes already afloat, rather than a general reopening of Iranian oil trade.

The licence showed that lawful movement of oil and the ability to settle payment are separate questions. The PING SHUN delivery to Vadinar on 1 April demonstrated that its shipping mechanism could work, while the evidence also identified banking gaps that limited other buyers.

As a US sanctions instrument, GL-U matters as an example of a time-limited authorisation for historical cargoes. Its fixed expiry required counterparties to assess sanctions cover against a specific legal deadline.

Key Issues

Iranian oil sanctions

General License U expires

On 19 April, General License U lapsed at 00:01 EDT without a replacement licence or Federal Register notice. The lapse ended its legal cover for Iranian crude shipments already in transit.

The deadline made General License U a compliance test for traders, insurers and buyers handling cargoes loaded before 20 March. Treasury renewed Russia's GL-134B on the same day, so the decision not to renew GL-U was a distinct Iran policy choice rather than an administrative delay. For General License U, that contrast fixed its role as a temporary channel, not a reopening of Iranian oil trade.

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

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.
