Background

The United States Department of the Treasury manages federal finances, government borrowing, currency and financial policy. Its responsibilities include revenue collection and economic sanctions. The Office of Foreign Assets Control, known as OFAC, administers sanctions programmes within the department.

OFAC designates people and organisations under specific legal authorities, blocking property and restricting transactions within the applicable jurisdiction. General licences permit defined categories of activity that would otherwise be prohibited. Specific licences authorise individual transactions or arrangements. Treasury uses these instruments alongside its wider financial responsibilities, affecting banks, insurers and businesses whose transactions fall within US sanctions rules.

Key Issues
Russian asset sales

Treasury extends the Lukoil negotiation window

Treasury’s Office of Foreign Assets Control issued General License 131K on 21 October 2026. It permits covered sale negotiations, contingent contracts and maintenance or wind-down activity for Lukoil International GmbH and entities it owns by 50% or more. The permission runs until 12:01 a.m. EST on 21 November.

Treasury retains a separate approval decision over completing any sale. The licence replaces General License 131J and prohibits transfers of funds to people or accounts in Russia. Its negotiation permission therefore leaves both the final transaction approval and the payment restrictions within OFAC’s control. Licence text

Iran enforcement

Treasury targets shipping intermediaries

On 21 October 2026, Treasury sanctioned Karnakis and Karnakis, a Panama City law firm with a Piraeus office, alongside five Panamanians, three companies and nine ships. The action reached a business registering ship-owning companies. Treasury also issued a safety licence for seven ships lasting until 20 November.

The department had acted against Iranian financial and shipping networks throughout the month. Between 5 and 15 October, it warned foreign banks, designated twenty-two ships and associated firms, and listed exchange houses and offshore banks. Treasury attributed the targeted relationships to Iranian business, using designations against both vessels and the intermediaries handling their ownership or payments.

Cuba sanctions

Treasury narrows Cuba’s banking access

Treasury’s rule effective on 30 September 2026 ended permission for US banks to open or maintain accounts for Cuba’s private entrepreneurs. It also removed group people-to-people travel authorisation and certain payments between foreign banks routed through American banks. The rule implemented a presidential directive signed on 30 June 2025.

On 15 October, Treasury separately designated Banco Internacional de Comercio, freezing property within US jurisdiction and barring American banks from dealing with it. That followed its September action against Banco Exterior de Cuba. The department thus combined changes to standing transaction permissions with individual bank designations.

Reference

What is OFAC and how does it enforce sanctions?
The Office of Foreign Assets Control (OFAC) is the Treasury division that administers US economic and trade sanctions. It designates individuals, entities, and countries, freezes assets, and can grant limited waivers through instruments like General Licenses.
What is the US Treasury Department?
The US Department of the Treasury, founded in 1789, is America's principal federal economic and financial agency. It collects taxes, manages government debt, and through OFAC administers economic sanctions.
Is OFAC's General Licence 131H a replacement for the lapsed Russia crude-oil waiver?
No. General Licence 131H, issued 24 July 2026, covers payment for legal services and replaces a reporting requirement with a recordkeeping one. It is not a successor to the lapsed GL 134C crude-oil waiver, and OFAC had issued no replacement for that waiver as of early August 2026.Source: US Treasury OFAC
When did OFAC last designate an Iran-linked sanctions network before the Zanjani round?
OFAC's previous major Iran action was the 14 July 2026 designation of more than 50 individuals, entities and vessels tied to Mohammad Hossein Shamkhani's shipping network.Source: OFAC
What is OFAC General Licence 134C and when does it expire?
GL 134C expired at 12:01 EDT on 17 June 2026. No successor licence (GL 134D) has been issued; as of 13 July 2026 the gap had reached 26 days, the longest of the war.Source: OFAC
What was the Adani OFAC settlement and why does it matter for European oil traders?
OFAC fined Adani Enterprises $275 million for 32 Iran-LPG sanctions violations in May 2026, the largest commodity-chain enforcement action of the year. It sets the prosecution benchmark for European traders holding Russian cargoes loaded under lapsed waivers.Source: OFAC
Why did Treasury extend the Russia oil waiver but not Iran's?
On 19 April 2026 Treasury signed an extension of Russia's seaborne-oil General License 134B to 16 May while letting Iran's General License U lapse on the same day. It was the first asymmetry in signed US sanctions text between the two programmes.Source: US Treasury
Why did Treasury summon bank CEOs about an AI model?
Scott Bessent and Jerome Powell summoned bank CEOs on 8 April 2026 after Anthropic released Claude Mythos Preview, an AI capable of autonomously identifying thousands of zero-day security vulnerabilities. It was the first Treasury convening of Wall Street specifically over a frontier AI system.Source: editorial
How is the US Treasury enforcing Iran sanctions in July 2026?
OFAC's designation of more than 50 individuals, entities and vessels tied to Mohammad Hossein Shamkhani's shipping network (14 July 2026) stands as the settled sanctions action. The wind-down licence, General Licence X1, lapsed for good on 17 July 2026 with no successor issued, ending the Iranian oil-waiver framework that had run via General Licences X and X1.Source: OFAC recent-actions record, 14 Jul 2026
What does Scott Bessent's Treasury policy mean for oil markets in 2026?
Bessent has pursued asymmetric enforcement: extending Russian crude waivers while cutting Iranian ones, then allowing Russian waivers to lapse in May 2026 while posting the Adani Iran-LPG settlement. The direction of travel is toward base-regime enforcement rather than managed tolerance.Source: US Treasury
What OFAC sanctions have targeted Iran in 2026?
OFAC designated the Hengli Petrochemical network and 39 entities under sb0472 with first nuclear framing on 24 April; designated 14 Iran missile and drone targets under NSPM-2 in the fifth nonproliferation round; named Indian nationals and firms in the Shamkhani network on 15 April; and issued General License V covering TRON wallets. The White House signed zero presidential Iran instruments across the same period.Source: OFAC
Did the US Treasury renew the Iran oil waiver in April 2026?
No. On 19 April 2026 OFAC allowed General License U to lapse with no renewal. It had authorised 325 tankers carrying roughly $31.5 billion of Iranian crude already at sea.Source: US Treasury
