By Eduardo Bacci — The Investigative Journal
The first two weeks of May 2026 delivered one of the most consequential bursts of U.S. sanctions and trade-enforcement activity of the year. The Trump administration opened a new sanctions regime against Cuba’s military-economic conglomerates, escalated its “Economic Fury” campaign against Iran’s Islamic Revolutionary Guard Corps (IRGC) oil-export apparatus, and weathered a fresh judicial setback to one of its Section 122 tariff actions. Treasury, Commerce, and the Justice Department all moved in the same week. The combined effect is a sanctions perimeter that is wider, more secondary in nature, and more litigated than it was a month ago.
What follows is a structured digest of the eight enforcement and trade-policy developments most worth tracking. Each item summarizes the action, identifies the affected parties, and flags the implications for industry compliance teams, foreign financial institutions, and counterparties operating in the corridor between U.S. national-security policy and global commerce.
1. OFAC Hits IRGC Oil-to-China Network in Latest “Economic Fury” Round (May 11)
On May 11, 2026, Treasury’s Office of Foreign Assets Control (OFAC) designated 12 individuals and entities for their roles in enabling the IRGC’s sale and shipment of Iranian crude to the People’s Republic of China, according to the Treasury press release. The designations target the IRGC Shahid Purja’fari Oil Headquarters and its commercial and financial leadership, including Ahmad Mohammadi Zadeh, Samad Fathi Salami, and Mohammadreza Ashrafi Ghehi.
OFAC named cover companies in Hong Kong (Hong Kong Blue Ocean Limited and Hong Kong Sanmu Limited), the United Arab Emirates (Blanca Goods Wholesaler LLC), and Oman (Zeus Logistics Group) — all said by Treasury to obfuscate the IRGC’s role in moving oil to overseas buyers. The State Department framed the round as part of the broader maximum-pressure architecture.
Records indicate Treasury describes the Economic Fury campaign as having disrupted billions in projected oil revenue, frozen nearly half a billion dollars in regime-linked cryptocurrency, and pressured Tehran’s shadow banking networks. For compliance officers at commodity trading houses, the practical takeaway is that Hong Kong and Gulf-incorporated front entities remain the most heavily scrutinized vectors for Iran-origin crude — and that the IRGC’s pyramidal structure puts pressure on counterparties to perform 50-percent-rule diligence even on opaque ownership chains.
2. OFAC Targets Iran’s UAV and Weapons Procurement Supply Chain (May 8)
Three days earlier, OFAC issued a parallel Non-Proliferation and Iran-related Designations tranche, focusing on the foreign procurement networks that supply Iran’s UAV and missile programs. The action ensnared a China-based individual, Li Genping, and his company Hitex Insulation Ningbo Company Limited, along with Mohammadmahdi Maleki, an Iranian national based in Belarus, and the Belarus-incorporated Center for Innovation and Technology Cooperation.
The designations were issued under the NPWMD (non-proliferation of weapons of mass destruction) and IFSR (Iranian Financial Sanctions Regulations) authorities, and both individuals were flagged as subject to secondary sanctions. That secondary-sanctions designation matters: it effectively warns non-U.S. financial institutions that processing transactions for the designated parties exposes their U.S. correspondent banking relationships to termination risk.
Filings indicate the listed companies operate in dual-use components — insulating materials and electronics packaging — that have been a persistent sore spot for export-control authorities because of their commodity status outside of the U.S. Commerce Control List. The action is consistent with the State Department’s stated focus on Iran’s overseas military procurement networks rather than purely on Tehran-domiciled entities.
3. New Cuba Executive Order Builds a Standalone IEEPA Regime (May 1)
On May 1, the President signed Executive Order 14404, “Imposing Sanctions on Those Responsible for Repression in Cuba and for Threats to United States National Security and Foreign Policy,” and Treasury issued the implementing recent action. The order — published in the Federal Register on May 7 — establishes a new Cuba-related sanctions program under the International Emergency Economic Powers Act (IEEPA) that operates separately from, and in addition to, the longstanding Cuban Assets Control Regulations.
Filings indicate E.O. 14404 authorizes blocking sanctions against any foreign person determined to “operate in or have operated in the energy, defense and related materiel, metals and mining, financial services, or security sector of the Cuban economy.” Critically, it authorizes secondary sanctions against foreign financial institutions that engage in certain dealings with parties sanctioned under the order. As outside counsel notes, this is the most aggressive Cuba-related extraterritorial framework since the Helms-Burton Act of 1996.
Six days later, on May 7, the State Department made the first SDN designations under the new authority, including the Cuban military-owned conglomerate Grupo de Administración Empresarial S.A. (GAESA). The implications cascade: European, Latin American, and Asian banks with any prior exposure to the Cuban tourism, defense, or energy sectors now face a structural compliance question, not merely a transactional one. The new Cuba FAQs published on May 7 partially clarify the wind-down expectations for foreign counterparties.
4. DOJ Opens Criminal Probe into $2.6 Billion in Iran Oil Trades (May 7)
The Department of Justice opened a criminal investigation into roughly $2.6 billion in oil trades that may have violated Iran sanctions, according to reporting summarizing the probe. Records suggest DOJ’s Fraud Section and OFAC are jointly reviewing trading records and bank transfers from transactions conducted over the past two years, with subpoenas already issued to trading firms based in Geneva and Dubai.
No charges have been filed and the case remains a pending investigation. That distinction matters: the case is still at the document-production stage, and any reporting that names specific firms or executives at this point should be treated as allegation rather than finding. What is unusual is the scale — $2.6 billion is at the upper end of recent Iran-evasion case theories — and the apparent involvement of major international correspondent banks. Legal experts cited in the reporting flagged the potential for billions in fines if charges proceed.
For commodity traders and trade-finance banks, the probe reinforces the converging-risk pattern that DOJ has telegraphed since 2023: sanctions evasion is no longer prosecuted in isolation but is bundled with money-laundering and Bank Secrecy Act theories that elevate corporate criminal exposure.
5. USTR Initiates the Second Four-Year Review of Section 301 China Tariffs (May 6)
On May 6, the U.S. Trade Representative initiated the statutory second four-year review of the Section 301 tariffs imposed on Chinese imports following the 2018 investigation of China’s technology-transfer and intellectual-property practices. Domestic industry representatives may submit continuation requests for the July 6, 2018 tariff action between May 7 and July 5, 2026, with a parallel window opening June 24 for the August 23, 2018 action.
If no continuation requests are received in either window, the underlying Section 301 trade actions will terminate on July 6 and August 23, 2026, respectively. The procedural choreography effectively forces every industry group that wants the existing duties preserved to put its case on the record this summer. For supply-chain managers, the review is the most consequential trade-policy procedural event of the year because it shapes the post-2026 baseline tariff structure on Chinese imports.
6. Court of International Trade Strikes Down Section 122 Tariffs (May 7)
On May 7, the Court of International Trade ruled that the 10% tariffs established under Section 122 by Presidential Proclamation No. 11012 are invalid. Section 122 authorizes the President to impose temporary import surcharges to address balance-of-payments problems but caps duties at 15% and limits them to 150 days unless extended by Congress. The court’s decision is the first significant judicial constraint on the second-term tariff toolkit and is expected to be appealed to the Federal Circuit.
The ruling does not by itself affect the Section 232 tariffs on steel, aluminum, and copper, which were restructured by proclamation in early April to apply a 50% rate to in-scope metals and a 25% rate to derivative products on the full customs value of the import. But the Section 122 ruling does narrow the executive’s freelance-tariff authority and will likely intensify reliance on Section 232 and IEEPA-based tariff theories that face their own pending Supreme Court review.
7. OFAC Updates Designations on CJNG-Linked Mexican Casino Network (May 8)
On May 8, OFAC updated identifiers for Kovay Gardens — a Mexican timeshare resort previously designated for fraud conducted on behalf of the Cartel de Jalisco Nueva Generación (CJNG) — flagging its operation under new aliases Navira Villas & Residences and Marina Oasis Beachfront Resort. The entity was previously designated under Executive Order 14059 (narcotics trafficking) and Executive Order 13224 (counter-terrorism), reflecting the administration’s continued use of dual designations against cartel-linked enterprises since cartels were designated as Foreign Terrorist Organizations earlier in the administration.
The action follows a more substantial April 14 designation tranche targeting a money-laundering and cash-smuggling network operated by the Cartel del Noreste in Nuevo Laredo, for which OFAC issued General License 35 authorizing wind-down through May 13, 2026. The casino-and-resort vector for cartel financial flows is now squarely inside the U.S. compliance perimeter, with hospitality-sector vendors, payment processors, and U.S. citizens holding timeshare interests all exposed.
8. Treasury Refines Venezuela Bond Authorization with General License 5W (May 4)
On May 4, OFAC issued Venezuela General License 5W, authorizing certain transactions involving the Petróleos de Venezuela, S.A. 2020 8.5 Percent Bond on or after June 19, 2026. The license sits inside the broader post-Maduro sanctions architecture that has been incrementally adjusted since January’s narco-terrorism extradition. Notwithstanding the change in regime in Caracas, Treasury has consistently signaled that the Venezuela sanctions program remains in place; selective general licenses are being used to manage specific legal contingencies, not to dismantle the program wholesale.
For bondholders and restructuring advisors, GL 5W is procedurally narrow — it does not authorize broader Venezuelan oil-sector dealings — but it removes one technical impediment to legitimate creditor activity around the matured 2020 PdVSA bond.
Items Warranting Deeper TIJ Investigation
Three threads stand out for follow-up. First, the DOJ’s $2.6 billion Iran-oil probe will be a defining test of how aggressively prosecutors are willing to pursue executive criminal liability at major commodity trading houses; the witness list and any unsealed indictments deserve close tracking. Second, the Cuba Executive Order’s secondary-sanctions teeth — particularly its application to foreign financial institutions — has not yet been tested against any sovereign-owned bank, and the first such designation will reset the compliance posture across Latin American and European banking. Third, the Court of International Trade’s Section 122 ruling foreshadows the deeper constitutional fight over IEEPA-based tariffs that the Supreme Court is expected to take up later this year; the appellate record now being built in Section 122 will shape that argument.
Across all eight items, the pattern is unmistakable: U.S. sanctions and trade enforcement are converging on a model where designation, criminal prosecution, and tariff policy are deployed as a single coordinated lever. Compliance programs built for one of those vectors but not the others will be the most exposed in the months ahead.
