The Investigative Journal’s weekly digest of U.S. sanctions and trade enforcement, drawn from Treasury, Commerce, and related public records. All items below are administrative actions unless otherwise noted; no criminal findings are implied.
The first full week of September brought no let-up in Washington’s economic pressure campaign against Tehran, as the Treasury Department extended Operation Economic Outcast into the Turkish banking sector with the designation of an Istanbul investment bank. The week also produced new Cuba designations aimed at the island’s financial and resource-extraction apparatus, a set of Venezuela general licenses suggesting a calibrated opening in that country’s minerals sector, a quiet Russia-related delisting worth watching, and a compliance deadline with enforcement teeth. Here is what the public record shows.
1. Treasury designates Türkiye’s Golden Global Bank over Iran ties — the week’s top action
On September 4, the Office of Foreign Assets Control (OFAC) designated Golden Global Yatirim Bankasi A.S. (Golden Global Investment Bank), an Istanbul-based financial institution, along with two subsidiaries — Golden Global Varlik Kiralama A.S. and Golden Global Portfoy Yonetimi A.S. — under Executive Order 13902, which targets Iran’s financial sector. According to Treasury’s press release, the bank “facilitated tens of millions of dollars’ worth of transactions” for the Islamic Revolutionary Guard Corps-Qods Force (IRGC-QF) and provided the Iranian regime with correspondent banking access to move funds internationally.
Treasury’s release states the bank was established to enable Iran’s “rahbar” network to transfer oil revenues from China to Türkiye, where records suggest the funds could be converted to cash and gold by affiliated money exchangers. The department also tied Golden Global to the network of Turkish businessman Sitki Ayan, sanctioned by OFAC in 2022 for allegedly moving hundreds of millions of dollars related to IRGC-QF oil sales. “Financial institutions continue to find out the hard way that we are serious about Operation Economic Outcast,” Treasury Secretary Scott Bessent said in the announcement. The SDN List entries show the bank was established in October 2019 — meaning it operated for nearly seven years, including four after the Ayan network designations, before being cut off.
OFAC concurrently issued Iran General License CC, authorizing a wind-down of transactions involving the newly blocked entities. The implications for Türkiye’s banking sector are significant: foreign financial institutions that knowingly conduct significant transactions with the designated bank now face secondary sanctions exposure, including potential loss of U.S. correspondent accounts. The designations are administrative measures, not criminal charges, and listed persons may petition OFAC for removal.
2. Operation Economic Outcast’s widening net: the Banque Misr UAE proposal
The Türkiye action follows the August 28 move against Iran’s banking access in the Gulf. Under the same campaign, Treasury’s Financial Crimes Enforcement Network (FinCEN) proposed a rule that would revoke the U.S. correspondent banking access of Banque Misr UAE — the Emirati operation of the Egyptian state-owned bank — after Treasury assessed it processed approximately $1.8 billion between January 2024 and June 2026 for 103 companies “potentially part of Iranian shadow banking networks.” The notice of proposed rulemaking, issued under Section 311 of the USA PATRIOT Act, applies only to the UAE operations, not to Banque Misr elsewhere, and remains open for public comment.
The same day, OFAC designated Reza Mohammad Taeedi, whom Treasury identifies as general manager of Bank Melli’s Dubai branch, under counterterrorism authority E.O. 13224, and Hong Kong-based Kameng Trading Limited under E.O. 13902 for allegedly helping a sanctioned Iranian exchange house launder funds. Taken together with the August 24 launch of Operation Economic Outcast — which Treasury dubbed “Economic D-Day” and which included nearly 60 designations and suspended general licenses — the sequence shows Treasury working outward from Iran’s borders through the third-country financial institutions that, filings indicate, keep the regime connected to the dollar system. For banks in Türkiye, the UAE, and Hong Kong, the compliance message is that geography offers no insulation.
3. Cuba: designations reach the island’s banks, oil imports, and nickel trade
On September 3, OFAC added five Cuban entities and one individual to the SDN List under E.O. 14404. The entities span Cuba’s external financial and resource infrastructure: Banco Exterior de Cuba; Comercial CUPET S.A., a state fuel-trading enterprise; ABAPET, an oil-sector import company OFAC links to Unión Cuba-Petróleo; CEXNI, the nickel-sector import and supply enterprise in Moa; and NICAROTEC, a mining-services enterprise in Mayarí. The individual, Fidel Ernesto Castro Calis, is listed by OFAC as linked to Alejandro Castro Espín. A companion State Department fact sheet describes the action as targeting “Cuba’s elites, financial channels, and resource exploitation apparatus.”
The nickel-sector listings are the ones for industry to watch. Cuba’s Moa region is a meaningful node in global nickel and cobalt supply, and the designation of the import-supply enterprises that keep those operations running creates diligence questions for any trader whose counterparties touch Cuban-origin material. OFAC simultaneously issued Cuba General License 4A, authorizing transactions for third-country diplomatic and consular missions in Cuba — a carve-out that keeps embassies functioning while the designations bite.
4. A quiet Russia-related delisting: Dulac Capital Ltd
Tucked into the same September 3 notice, OFAC removed Dulac Capital Ltd — a Zurich-registered company with representative offices in Moscow and St. Petersburg — from the SDN List, where it had been designated under Russia authority E.O. 14024. OFAC does not typically publish its reasoning for removals, which can follow petitions demonstrating changed ownership, behavior, or circumstances.
Delistings receive far less scrutiny than designations, and that asymmetry is itself a story. Who petitioned for Dulac Capital’s removal, what changed at the company, and what the decision signals about Treasury’s current Russia posture are questions the public record does not yet answer. TIJ has flagged the removal for follow-up.
5. Venezuela: general licenses open a controlled lane for coal, minerals, and gold
On September 2, OFAC issued three amended Venezuela-related general licenses: GL 51D, authorizing certain activities involving Venezuelan-origin coal or minerals, including gold; GL 54C, authorizing the supply of items and services for coal or minerals operations; and GL 55A, authorizing negotiation of and entry into contingent contracts for investment in Venezuela’s coal or minerals sectors. OFAC also amended FAQ 1247.
The pattern in these authorizations — activity, supply, and contingent investment contracts — suggests a deliberately sequenced framework for U.S. and foreign firms to position in Venezuelan extractives while broader sanctions remain in place. For miners, commodity traders, and their banks, the licenses create opportunity wrapped in compliance risk: the authorizations are conditional, amendable, and revocable, and the gap between what a general license permits and what a counterparty actually does is where enforcement cases are born.
6. Compliance corner: blocked-property reports due September 30
The same September 2 notice carried a reminder with teeth: U.S. persons holding blocked property as of June 30, 2026 must file the Annual Report of Blocked Property by September 30, and OFAC states that failure to file “may lead to an enforcement referral.” With the pace of designations this year — Iran, Cuba, and counterterrorism actions among them — the universe of institutions holding newly blocked assets has grown, and so has the population of potential non-filers. Banks, funds, and even law firms holding blocked funds should treat the deadline as an enforcement trigger, not a formality.
7. Export controls: BIS keeps up administrative enforcement tempo
The Commerce Department’s Bureau of Industry and Security posted administrative enforcement settlements with Plexon, Inc. (August 14) and Container Manufacturing Ltd. (August 24), with the settlement orders published in its enforcement feed. The orders continue what records show has been an unusually active 2026 for BIS administrative penalties: Robert Bosch GmbH agreed in June to pay $36.2 million over shipments of sensor products to Huawei affiliates captured by the Foreign Direct Product Rule, and Applied Materials agreed in February to a $252 million penalty — the second-highest in BIS history — over semiconductor equipment that reached China through a Korean affiliate.
The through-line in these cases is indirect exposure: items moving through affiliates, assembly hubs, and third countries before reaching listed parties. With BIS’s affiliates rule extending Entity List restrictions to majority-owned subsidiaries of listed companies, exporters’ diligence obligations now run through ownership chains, not just named counterparties — and the settlement pace indicates BIS intends to enforce that expectation.
8. CFIUS: annual report shows steady deal scrutiny, streamlining for known investors
The Committee on Foreign Investment in the United States released its annual report to Congress covering calendar year 2025, and analyses of the report circulated this week. According to the report, CFIUS reviewed 347 covered transactions in 2025 — 207 written notices and 140 declarations. Treasury has also been piloting a “Known Investor” portal intended to reduce filing burdens for low-risk, repeat foreign investors, part of a broader posture that pairs faster lanes for allied capital with tighter conditions on investors maintaining commercial ties to U.S. adversaries.
For dealmakers, the message from the data is continuity: filing volumes remain high, and mitigation conditions — including, in some cases, requirements that foreign investors unwind relationships with adversary-country partners — are becoming a standard feature of clearances rather than an exception.
What warrants deeper investigation
Several threads from this week merit sustained TIJ attention. First, Golden Global Bank’s seven-year run: the bank was established in 2019, and Treasury’s own releases link it to a network sanctioned in 2022 — which raises the question of which European and Gulf correspondents maintained relationships with it in the interim, and what their screening showed. Second, the 103 companies Treasury says moved $1.8 billion through Banque Misr UAE: corporate registries in the UAE and Hong Kong should yield names, directors, and formation agents. Third, Dulac Capital’s path off the SDN List, and who advocated for it. Fourth, the counterparties now negotiating contingent contracts under Venezuela GL 55A, and what those contracts promise if sanctions lift. Finally, the IEEPA tariff aftermath: following the Supreme Court’s February decision striking down IEEPA-based tariffs, refund and remedial questions remain in litigation at the Court of International Trade while the administration relies on other tariff authorities — a slow-moving story with billions at stake for importers.
Right of reply: the parties named above are the subject of administrative actions described in the cited government records; none has been criminally charged in connection with these actions unless noted. Persons designated by OFAC may petition for removal from the SDN List, and The Investigative Journal will report substantive responses from affected parties.
