ISTANBUL, Sept 5, 2026: The U.S. sanctions on Golden Global expose a wider struggle over the financial routes through which Iranian oil revenue moves from Chinese buyers into Iran’s economy—and Washington appears to be targeting intermediary jurisdictions while remaining cautious about directly confronting China’s major financial institutions.
The U.S. Treasury Department sanctioned Türkiye-based Golden Global Yatirim Bankasi Anonim Sirketi, along with its subsidiaries Golden Global Varlik Kiralama Anonim Sirketi and Golden Global Portfoy Yonetimi Anonim Sirketi, accusing them of facilitating financial transactions linked to Iran’s Islamic Revolutionary Guard Corps-Qods Force.
Treasury said Golden Global facilitated tens of millions of dollars in transactions for the IRGC-Qods Force and provided correspondent banking services to Iranian financial institutions.
Today, as part of Operation Economic Outcast, Treasury severed the Iranian regime’s critical financial lifelines in Türkiye. The Office of Foreign Assets Control designated Türkiye-based Golden Global Bank and its subsidiaries, which have facilitated tens of millions of dollars’…

More significantly, Treasury alleged that Golden Global was established to enable an Iranian “rahbar” network to transfer oil revenues from China to Türkiye, where the funds could be converted into cash and gold through money exchangers linked to the network.
The designation is part of Treasury’s wider Operation Economic Outcast, launched in August to disrupt Iran’s financial channels and increase pressure on foreign institutions that Washington says are facilitating Iranian oil revenues and sanctions-evasion networks.
Golden Global rejects US allegations
Golden Global has strongly rejected the U.S. allegations. In a statement issued after the sanctions, the Turkish bank said the individuals and entities identified in the U.S. action were not its customers and that it had no direct or indirect transactions with them.
The bank said it began operations in June 2020 after receiving authorization from Türkiye’s banking regulator and had complied with domestic and international banking and compliance requirements. It also said it had undergone internal and external audits.
Golden Global said it would use all available legal and objection mechanisms against the U.S. sanctions and maintained that it had the financial capacity to meet its obligations to stakeholders.

The dispute therefore presents two sharply different accounts. Washington alleges that Golden Global knowingly provided financial services that enabled Iranian networks linked to the IRGC-Qods Force. The bank denies dealings with the persons and entities identified by the U.S. Treasury.
No immediate response from the Turkish government was available on Saturday.
China at the centre of Iran’s oil lifeline
The Golden Global case is significant because China is the principal buyer of Iranian oil. The U.S. Treasury has estimated that Chinese buyers account for about 90 percent of Iran’s oil exports and has repeatedly targeted Chinese companies and other intermediaries involved in purchasing, transporting or facilitating Iranian petroleum.
Iran’s oil trade with China has also increasingly relied on the Chinese yuan rather than the U.S. dollar. Treasury has said Iran primarily settles its oil sales in Chinese yuan, with Iranian exchange houses subsequently converting yuan proceeds into currencies that are easier to use internationally.
Research by the U.S. think tank Carnegie Endowment for International Peace has documented the growth of renminbi-based payment channels linking Chinese financial institutions with energy-exporting economies. Carnegie says Chinese payments for Iranian oil are primarily settled in renminbi and that such transactions have reportedly often involved mid-sized Chinese banks with limited connectivity to the dollar financial system.
China’s Cross-Border Interbank Payment System, or CIPS, forms part of this broader renminbi payment architecture. Carnegie describes CIPS as payment infrastructure that can enable bank-to-bank transactions without relying on U.S. or European financial institutions or messaging systems.
There is no evidence, however, that CIPS was used in the specific transactions cited by Treasury in the Golden Global designation. The U.S. Treasury has also not publicly identified a Chinese bank as the financial institution involved on the Chinese side of those transactions. That leaves a significant part of the alleged money trail undisclosed.
Inside Iran’s oil-revenue network
Treasury’s description points to a financial chain in which revenue generated by Iranian oil sales to Chinese buyers ultimately reached Türkiye and was converted into cash and gold.
The public designation, however, does not provide transaction-level details such as account numbers, individual payment records or the identity of every financial institution through which the money allegedly moved.
The distinction matters. China’s role as Iran’s dominant oil customer and the growing use of renminbi in Iranian oil transactions are independently documented.
The allegation that Golden Global provided correspondent banking services that enabled Iranian financial institutions and IRGC-Qods Force-linked networks to move funds into Türkiye comes from the U.S. Treasury.
What remains unclear publicly is which Chinese financial institutions or intermediaries processed the relevant funds before the alleged transfer into the Turkish financial system. That gap limits what can currently be established about the precise route taken by the money.
US sanctions reach deeper into third-country finance
The Golden Global designation forms part of the broader U.S. campaign against financial networks that Washington says support Iran’s oil trade and sanctions evasion. Treasury says Operation Economic Outcast is targeting networks, facilitators and financial channels used by Iran to move funds and evade sanctions, while expanding secondary-sanctions exposure for entities that continue doing business with the Iranian regime.
Recent U.S. actions have included Chinese and Hong Kong-based entities, UAE-linked financial networks and other intermediaries connected to Iran’s oil and financial infrastructure.
Treasury has also warned foreign financial institutions that involvement with sanctioned Iranian networks can expose them to secondary-sanctions risk. It says foreign financial institutions that knowingly facilitate certain significant transactions for designated persons can face restrictions on U.S. correspondent or payable-through accounts.
The Golden Global designation therefore brings a Turkish financial institution into that wider sanctions pressure.
Türkiye faces a financial and diplomatic challenge
The sanctions put a Turkish financial institution directly into a dispute involving Washington and Tehran. Türkiye is a NATO member and a U.S. ally, but the Golden Global designation is an action by the U.S. Treasury and OFAC, not a NATO decision. There is currently no evidence that Türkiye intends to make the Golden Global case a NATO issue. For now, the immediate challenge is financial and legal.
OFAC maintains a formal process through which sanctioned entities can petition for removal from its sanctions lists by presenting evidence and arguments. Treasury itself directs sanctioned parties to that process. Golden Global has said it intends to exercise its available legal and objection rights.
Any successful challenge could provide additional information about the transactions and financial relationships underlying the U.S. action.
A wider question for Iran’s oil trade
The Golden Global case ultimately goes beyond one Turkish bank. The ability of Iran to sustain its oil trade depends not only on finding buyers but also on converting oil revenue into usable financial resources. China is the principal market for Iranian crude, while renminbi-based payment mechanisms have created channels that can reduce reliance on traditional dollar-based transactions, according to U.S. Treasury and Carnegie Endowment research.
The U.S. campaign is increasingly targeting financial intermediaries outside Iran, particularly those Treasury identifies as helping Iranian networks move or convert oil proceeds. The Golden Global designation brings that strategy into Türkiye, while leaving the Chinese-side financial channel largely undisclosed.
That gap raises a broader question: through which Chinese financial institutions or intermediaries do Iranian oil revenues move before entering other jurisdictions such as Türkiye? The public record currently does not provide enough information to establish that part of the Golden Global money trail, leaving it as a key unresolved issue in understanding how Iran continues to move oil revenues despite U.S. sanctions.
