Common Questions
What is OFAC?
OFAC (Office of Foreign Assets Control) is the US Treasury body that administers economic sanctions, maintains the SDN list, and issues general licences creating temporary legal carve-outs.Source: Lowdown
What is OFAC General Licence U?
GL-U provided legal cover for up to 128 million barrels of Iranian crude already in transit to reach buyers without triggering US sanctions. It is set to expire on 19 April 2026.Source: Lowdown
What happens when OFAC GL-U expires?
Without renewal, buyers and intermediaries holding in-transit Iranian crude face immediate sanctions exposure, creating fire-sale pressure on the oil and pushing Brent Crude higher.Source: Lowdown
How does OFAC affect the Iran-Israel war?
OFAC's GL-U expiry on 19 April 2026 creates a hard diplomatic deadline: Iran faces mounting economic pressure unless a Ceasefire or extension is agreed before that date.Source: Lowdown
What is OFAC and how does it enforce Iran sanctions?
OFAC (Office of Foreign Assets Control) is the US Treasury bureau that administers economic sanctions. Its reach extends to any company using US dollars or US banks, giving it global jurisdiction. It maintains the SDN list and issues general licences for wind-down periods.Source: editorial
What happened when OFAC General License U expired in April 2026?
General License U, covering 325 tankers carrying $31.5 billion of Iranian crude, lapsed at 00:01 EDT on 19 April 2026 with no renewal. On the same day Treasury extended Russia's seaborne crude waiver (GL-134B), creating the first Russia-yes Iran-no asymmetry in signed US policy.Source: OFAC
Why did OFAC sanction Hengli Petrochemical?
OFAC designated Hengli Petrochemical (Dalian) Refinery Co. Ltd on 24 April 2026 under sb0472 for purchasing Iranian crude. Hengli was the largest single-entity Chinese designation in the 2026 conflict, processing an estimated 400,000 Barrels Per Day of Iranian oil.Source: OFAC
Has OFAC ever sanctioned cryptocurrency wallets linked to Iran?
Yes. On 24 April 2026, OFAC added two TRON blockchain wallet addresses to the Central Bank of Iran's SDN entry — the first time blockchain wallet addresses were attached to an Iranian state institution in the conflict.Source: OFAC
Why did OFAC take no action on Iran on 29 April?
On 29 April OFAC issued only GL-131E, authorising the sale of Lukoil International GmbH — a Russia instrument with no Iran component. It was the first Russia-only OFAC day of the war, breaking a six-week weekly Iran sanctions cadence.Source: OFAC
What is OFAC and how does it enforce sanctions?
OFAC (Office of Foreign Assets Control) is the US Treasury bureau that administers economic sanctions. Its reach extends to any company using US dollars or US banks, giving it global jurisdiction regardless of where a firm is based. It maintains the SDN list and issues general licences for wind-down periods.Source: editorial
Why did OFAC sanction a Chinese satellite company over Iran?
On 8 May 2026, OFAC designated Chang Guang Satellite Technology (CGSTL) under IRAN-CON-ARMS-EO authority, alongside a procurement network routing through Hong Kong, Shanghai, Belarus and Dubai. CGSTL is China's largest commercial SAR satellite operator; the action marks the first extension of arms-grade Iran sanctions to a Chinese commercial space firm and creates compliance exposure for every CGSTL customer globally.Source: OFAC
Has OFAC sanctioned Chinese companies over Iran oil purchases?
Yes. OFAC designated Hengli Petrochemical (Dalian) Refinery Co. Ltd on 24 April 2026 — the largest single-entity Chinese designation of the conflict, processing an estimated 400,000 bpd of Iranian crude. On 8 May it sanctioned CGSTL, China's largest commercial SAR satellite firm, under arms-related Iran authority.Source: OFAC
Is OFAC running Russia and Iran sanctions at the same time?
Yes. OFAC ran parallel Iran and Russia programmes through April-May 2026, exposing a structural asymmetry on 19 April when Russia's seaborne crude waiver was extended the same day Iran's GL-U lapsed. The 29 April Russia-only day — the first Iran-free OFAC action of the war — signalled deliberate cadence management across both tracks.Source: OFAC / editorial
Why did OFAC target Hong Kong companies in the 11 May 2026 Iran sanctions round?
OFAC designated four HK-registered shells on 11 May to exploit a gap in enforcement: MOFCOM Blocking Rules constrain direct action against mainland Chinese refineries but do not cover HK-registered companies. The round was timed ahead of the Trump-Xi summit to calibrate pressure without triggering a mainland China confrontation.Source: OFAC

Background

The Office of Foreign Assets Control (OFAC) is the US Treasury Department bureau responsible for administering and enforcing economic and trade sanctions based on US Foreign Policy and national security objectives. It maintains the Specially Designated Nationals (SDN) list and issues general licences that create targeted exemptions within broader sanctions regimes. OFAC's reach extends beyond US entities — any company transacting in dollars, clearing through US banks, or doing business with US-connected firms falls within its effective jurisdiction, making it a lever of global rather than bilateral economic pressure.

In April-May 2026, OFAC ran three active conflict programmes simultaneously. On Iran: General License U, covering 325 tankers carrying $31.5 billion of Iranian crude, lapsed at 00:01 EDT on 19 April with no renewal; on the same calendar day Treasury signed GL-134B extending Russia's seaborne-oil waiver to 16 May, producing the first Russia-yes, Iran-no asymmetry in signed US policy text . On 28 April, OFAC published sb0477 'Economic Fury Targets Iran Shadow Banking Facilitators', designating 35 entities and individuals — the first time OFAC deployed a 'fury' rhetorical register, mirroring Operation EPIC FURY military branding . On 8 May, OFAC added eight entities and three individuals under IRAN-CON-ARMS-EO authority, including Chang Guang Satellite Technology (CGSTL), China's largest commercial SAR satellite operator — the first extension of arms-grade Iran sanctions to a Chinese commercial space-imaging firm, a structural precedent that creates compliance exposure for every CGSTL customer globally . Then on 29 April, OFAC issued only GL-131E, authorising the Lukoil International GmbH sale — a Russia instrument with no Iran component — the first Russia-only OFAC day of the war, signalling a cadence break.

On 11 May 2026, OFAC's next Economic Fury round designated three individuals and nine entities including Universal Fortune Trading LLC (Dubai, direct NIOC link) and four Hong Kong-registered shells: Hong Kong Blue Ocean Limited, Jiandi HK Limited, Max Honor International Trade Co. Limited, and a fourth entity. The HK targeting exploited a deliberate gap in mainland China enforcement ahead of the Trump-Xi summit; MOFCOM Blocking Rules constrain OFAC action against mainland Chinese refineries but do not extend to HK-registered companies. The cumulative pattern across four Economic Fury rounds — CGSTL/CITC (8 May, ID:3168), NFRA Hengli (24 April, ID:3160), HK shells (11 May) — shows OFAC systematically mapping and designating each node of the IRGC crude-distribution architecture before closing the next. The supply-chain mapping pattern is now visible across both the Iran and Russia programmes: OFAC is systematically designating upstream technology providers (satellite imagery, precision components, shadow-banking networks) rather than primary commodity buyers alone.
