The move represents another step in the administration’s aggressive campaign to deprive Tehran of the foreign revenue it needs to sustain its government, finance overseas operations and work around existing U.S. sanctions.
Treasury Secretary Scott Bessent has dubbed that campaign “Operation Economic Outcast,” and Friday’s announcement made clear that Washington is increasingly willing to punish foreign institutions accused of keeping Iran connected to the global financial system.
“Financial institutions continue to find out the hard way that we are serious about Operation Economic Outcast,” Bessent said of Friday’s action.
The warning was not limited to Golden Global Bank.
Bessent signaled that banks and financial intermediaries around the world could face similar consequences if they continue conducting business that Washington believes benefits Tehran.
“While we hope no more banks will need to be sanctioned, that ultimately depends on how quickly the international community comes to its senses and ceases support of the murderous Iranian regime,” he added.
Bessent then delivered an even sharper warning to those allegedly assisting Iran.
“We know who you are, we know where you are, and we will continue to take action together with our allies and partners until we have buried the head of the Iranian snake.”
Golden Global Bank was established in 2019 and operates out of Turkey, a NATO member and longtime U.S. ally.
The institution bills itself as “Turkey’s first investment bank that conducts all its activities in accordance with interest-free finance principles.”
But Treasury officials allege that behind its relatively modest footprint was an important role in a much broader system used by Iran to move money across international borders.
Acting Treasury Department Under Secretary for Terrorism and Financial Intelligence Gene Lange said the bank had not been blindsided by Washington’s decision.
“This bank has been warned for years,” Lange said.
“We have repeatedly warned these entities, and today’s action makes clear that those warnings have consequences. This is a message to everyone else: the secretary means every single word he said at the press conference announcing Operation Economic Outcast.”
Treasury says Golden Global became connected to what officials describe as Iran’s “rahbar” exchange network.
According to the department, the system relies on front companies and financial intermediaries to take revenue generated from Iranian oil sales in China, route those funds into Turkey and eventually turn the proceeds into assets such as cash and gold.
That process allegedly provided Tehran with another avenue for obtaining money despite the web of sanctions intended to isolate the regime financially.
The Treasury Department said Golden Global and related entities “facilitated tens of millions of dollars’ worth of transactions for the Islamic Revolutionary Guard Corps-Qods Force (IRGC-QF) and provide the Iranian regime with key correspondent banking access that allows it to move its funds internationally.”
By imposing sanctions, Washington is seeking to make continued dealings with Golden Global extraordinarily costly for other financial institutions.
Treasury characterized the move as having “severed the Iranian regime’s critical financial lifelines” in Turkey.
The location of the bank makes the decision particularly significant.
Turkey is a member of NATO, meaning the administration is taking its pressure campaign into the financial sector of a formal U.S. ally rather than limiting enforcement efforts to Iran or countries more closely aligned with Tehran.
The action is believed to represent the first U.S. sanctions imposed directly against a Turkish bank.
There is, however, precedent for Washington taking legal action against a Turkish financial institution over alleged Iranian sanctions evasion.
Federal prosecutors charged Halkbank in 2019, accusing the institution of participating in a multibillion-dollar operation that helped Iran circumvent U.S. economic restrictions. That long-running case reached a legal settlement earlier this year.
Attention will now turn to Ankara and whether Turkish authorities take additional steps against Golden Global or assets associated with the institution.
It remained unclear immediately following Washington’s announcement whether Turkey would freeze, seize or otherwise restrict the bank’s holdings.
Golden Global is also not the only foreign financial institution to find itself in the Trump administration’s crosshairs.
Treasury has pursued entities elsewhere, including in the United Arab Emirates, over allegations that they provided financial services or banking access benefiting Iranian customers.
Friday’s sanctions therefore carry a message much larger than the fate of one Turkish institution.
The administration is attempting to force foreign banks into a stark choice: retain access to the American-centered international financial system or risk becoming part of the machinery Tehran allegedly uses to evade sanctions.
By following Iranian oil revenue beyond Iran’s borders and targeting the institutions accused of moving it, the administration is expanding the battlefield of its economic campaign.
And Bessent’s message suggests the pressure will not end with Golden Global.
For banks still willing to handle money linked to Tehran, Washington’s warning is increasingly difficult to ignore: helping Iran circumvent U.S. sanctions could now put their own access to the global financial system on the line.
