Key takeaway

OFAC's 50% rule meets China's state-owned-enterprise loophole; Treasury must choose by Sunday midnight.

Hengli Petrochemical International Pte, the Singapore trading arm of the OFAC-designated Dalian refinery, cut its parent-company stake from 100% to 5% and transferred 95% to Dalian Changxing International Trade Co Ltd, a Chinese government-linked trading House, two days before the Office of Foreign Assets Control (OFAC, the US Treasury sanctions bureau) General Licence V expires at midnight on Sunday 24 May . Per a client notice reported by Manifold Times, Hengli is arguing the Singapore unit is no longer majority-owned by a designated entity and should not be treated as sanctioned by association. Reuters reached out for comment; Hengli did not respond ¹.

The restructure is engineered around OFAC's 50% rule, the doctrine that any entity owned at least half by a designated person is itself designated by association. A state-to-state restructure tests Treasury differently from a private divestiture. A state-linked owner can follow Beijing's blocking-order policy on dollar-clearing without formal control by the designated parent, which makes genuine independence almost impossible for OFAC to verify from the outside.

The 2018 Rusal case is the live precedent. OFAC sanctioned the Russian aluminium producer in April 2018; aluminium prices spiked 35% and dollar-clearing froze across the industrial supply chain. Designation was lifted only in January 2019, after owner Oleg Deripaska restructured the company under independent directors with binding licensing terms Treasury could verify. A swap into another state-adjacent owner without those independence undertakings did not qualify. The 2026 question is whether a Chinese government-linked counterparty acquiring 95% of a designated subsidiary counts as Rusal-style independence or as a controlled divestiture that preserves the parent's economic benefit.

The restructure also probes the reach of MOFCOM's blocking order , which directs Chinese entities to disregard US sanctions but does nothing for the dollar-clearing layer, the international banking pipework where Singapore is a major Asia hub. Sunday's midnight deadline becomes the first live test of whether Beijing's blocking architecture extends to the place where dollars actually settle. Accept the restructure and entire sanctions regimes thin out; reject it and Beijing's blocking architecture is publicly exposed as porous at the clearing layer.

Deep Analysis

In plain English

The United States has placed sanctions on a Chinese oil refinery in Dalian, which means American banks cannot do business with it and any company that does faces penalties. The refinery has a separate trading company registered in Singapore that it owns 100% of, which has been doing business on its behalf. Two days before a deadline that would have forced banks to stop clearing US dollars for the Singapore company, the Dalian refinery transferred 95% of the Singapore company's ownership to a different Chinese state-linked trading house. The argument is: the Singapore company is no longer majority-owned by the sanctioned parent, so it shouldn't count as sanctioned by association. US sanctions rules say any company owned more than 50% by a sanctioned entity is itself automatically sanctioned. Hengli transferred 95% of the Singapore unit to Dalian Changxing two days before the deadline, arguing that the new owner is not the sanctioned parent. The problem: Dalian Changxing is a Chinese government company subject to a Chinese law that directs it to ignore American sanctions. So it's not really independent. The US Treasury now has to decide by Sunday midnight whether to accept that argument or reject it.

Deep Analysis

Root Causes

OFAC's 50% rule was designed around private-sector ownership architectures, not state capitalism. The rule's logic assumes that legal ownership is a reliable proxy for economic control and that ownership restructures into independent private parties genuinely break the sanctioned entity's ability to direct operations.

In a state-capitalist system where the acquiring party is a government-linked trading house subject to a blocking order, neither assumption holds: the state can direct the subsidiary's behaviour through political channels that do not appear in the ownership register. China's MOFCOM blocking order architecture is precisely designed to exploit this gap; it creates a legal instruction for Chinese entities to defy OFAC while maintaining formal compliance with OFAC's ownership rules.

The timing pressure from GL V's 24 May expiry is a structural product of OFAC's general-licence instrument design. General licences provide wind-down periods that allow market actors to restructure before a designation becomes effective; they were not designed to provide a runway for sanction-avoidance architectures to be assembled under safe harbour.

Hengli's 72-hour pre-expiry restructure tests whether the wind-down period's protective intent extends to ownership transfers whose independence cannot be verified.

What could happen next?

Precedent
OFAC's decision before Sunday midnight sets the template for every other designated Chinese refiner (Shandong Chambroad, Yulong, Rongsheng and others under MOFCOM's blocking order). If Hengli's state-to-state transfer holds, each designated refiner has a road map for escaping the 50% rule via Chinese state intermediaries.
Immediate · Assessed
Risk
Secondary sanctions applied to Singapore clearing banks would disrupt Iranian crude transactions routed through Singapore, affecting East Asian refiners whose supply chains run through the hub. Japan, South Korea and Taiwan are particularly exposed as refinery importers who source through Singapore-settled spot markets.
Short term · Assessed
Consequence
MOFCOM's blocking-order architecture is publicly tested at the dollar-clearing layer for the first time. Beijing's blocking strategy has been untested in practice because it relies on Chinese entities defying OFAC while maintaining access to dollar clearing. An OFAC rejection forces that contradiction into the open.

Primary parallel: In April 2018, OFAC designated Rusal, the world's second-largest aluminium producer, under the Deripaska sanctions. Aluminium prices spiked 35% within 48 hours. OFAC extended general licences three times over nine months while negotiating a restructure that required Oleg Deripaska to reduce his stake below 50%, install a board majority of independent non-sanctioned directors, and accept binding compliance undertakings Treasury could monitor.

Designation was lifted in January 2019 only after those independence criteria were demonstrably met. The critical distinction: Rusal's restructure was into genuinely independent private-sector counterparties; the 2026 Hengli restructure is into a Chinese government-linked trading House that is simultaneously subject to Beijing's blocking order directing it to defy OFAC. The Rusal standard requires demonstrated independence; Dalian Changxing is structurally incapable of demonstrating it while MOFCOM's blocking directive stands.

Counter-parallel: OFAC declined to designate COSCO Shipping Tanker (Dalian) in 2019 despite its central role in Iranian crude transport, citing the systemic risk of sanctioning a major Chinese state enterprise.

The non-designation established an informal threshold: entities with sufficient systemic importance to global dollar-clearing receive informal protection. Dalian Changxing is smaller than COSCO but its Singapore clearing role sits in the same category of dollar-denominated trade that OFAC has historically been reluctant to disrupt at the clearing-hub level.

Hengli Petroleum Singapore routes Iranian crude purchases through the Singapore banking system, where US-dollar correspondent clearing is mandatory for most transactions. After GL V expires, any Singapore bank clearing a Hengli transaction risks secondary sanctions. A successful restructure into Dalian Changxing breaks that chain only if Changxing can demonstrate it is not acting on behalf of the designated parent; which MOFCOM's blocking order makes impossible to verify.

If OFAC rejects the restructure and applies secondary sanctions to Singapore clearing banks, the contagion effect runs through the Asia hub system. Singapore is the primary settlement point for Gulf crude destined for East Asian refiners.

A secondary-sanctions action against a Singapore clearing bank would signal to other Asia-hub banks (Hong Kong, Tokyo, Seoul) that facilitating Iranian crude transactions is legally untenable regardless of the direct-counterparty designation status. That cascading effect is what Hengli's client base; and Beijing's blocking-order architecture; is designed to prevent.

Consensus view: Richard Nephew, former OFAC sanctions architect (currently at Columbia University's Center on Global Energy Policy), has consistently argued that the 50% rule's weakness is that it treats legal ownership as a proxy for economic benefit; a proxy that fails when a state-owned enterprise acquires a designated entity's subsidiary, because the acquiring SOE can direct the subsidiary's commercial conduct without holding a formal majority in the designated parent.

Nephew wrote in March 2025 that a state-to-state restructure into a Chinese government-linked counterparty is the precise scenario where OFAC's rules produce 'verification-impossible' outcomes: Treasury cannot confirm independence because the acquiring entity is subject to Beijing's blocking order.

Counter-view: The China Institute of International Studies, Beijing, argues that MOFCOM Announcement No. 21 functions as a legal carve-out that renders the OFAC 50% rule inapplicable within China's jurisdiction: because Chinese law directs entities to disregard the designation, the 95% stake held by Dalian Changxing is not meaningful 'control' in OFAC's sense but rather a state administrative act.

Under this reading, the restructure is compliant with both Chinese and US law simultaneously, on the theory that jurisdictional conflict dissolves OFAC's operative premise.

Key tension: Whether OFAC will treat Dalian Changxing's acquisition as a genuine ownership change that satisfies the 50% rule's intent, or as a controlled divestiture that preserves the designated entity's economic benefit through a state-owned intermediary; a question Treasury must answer before Sunday midnight without a precedent that covers state-to-state transfers in a blocking-order jurisdiction.

Different Perspectives

China

Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.

Israel

IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.

Bahrain

The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.

Qatar

Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.

Kuwait

Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.

United States

Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.

Key Figures

Stake transferred from Hengli parent to Dalian Changxing95%

In everyday terms

If OFAC accepts the restructure, it weakens the sanctions architecture that has been one of the main tools limiting Iranian oil revenues. Lower oil revenues weaken Iran's ability to fund the conflict, but also lower global oil prices; a mixed effect for consumers. If OFAC rejects it and applies secondary sanctions to Singapore clearing banks, Asian oil trade could be disrupted, pushing prices higher.

What’s Uncertain

Whether OFAC will rule before Sunday midnight or let the deadline pass without a decisionOFAC has the option to issue a notice of intention to reject while extending GL V further, rather than issuing a binary accept/reject decision by midnight. A further extension would allow the restructure to stand while Treasury builds an enforcement case, but would also signal that the state-to-state transfer is in a grey zone.

Dalian Changxing's actual relationship to the Chinese stateReports describe it as 'government-linked' but the precise ownership structure; directly state-owned, local government-linked, or partly private; affects whether it falls under MOFCOM's blocking order as a matter of Chinese administrative law.
