The US Treasury Department said on Friday it imposed new Iran-related sanctions on a small Turkish investment bank and two subsidiaries as part of the Trump administration's effort to increase economic pressure on Iran.
The entities targeted are Instanbul-based investment bank Golden Global Yatirim Bankasi Anonim Sirketi, asset manager Golden Global Portfoy Yonetimi Anonim Sirketi, and asset leasing company Golden Global Varlik Kiralama Anonim Sirketi, according to the Treasury's Office of Foreign Assets Control.
The sanctions put all three entities on the Treasury's OFAC Specially Designated Nationals list, cutting them off from the dollar-based financial system.
The Treasury Department also issued a general license to allow the wind-down of transactions with the sanctioned entities.
In an interview with news outlet America's Voice News, US Treasury Secretary Scott Bessent said that the latest action "is code for you are out of business."
"And we will probably sanction another bank next week, and we are telling the financial system bad actors: 'We know who you are, you know who you are, it's over, and our allies are helping with this," he said.
Golden Global Yatrim Bankasi is the 35th-largest bank in Turkey by total assets, according to database TheBanks.EU, with total assets of 25,024.68 million Turkish lira ($516.63 million) in 2025.
The bank did not immediately respond to a request for comment.
The Treasury said in a statement that Golden Global was established for the purpose of enabling Iran's shadow banking network to transfer oil revenues from China to Türkiye,
where it could then be converted to cash and gold by money exchangers.
The Treasury said that Golden Global has knowingly offered to provide correspondent banking services to Iranian financial institutions, enabling transactions through accounts controlled by the Iranian Revolutionary Guard Corps Qods Force and its proxies.
The action is the latest in the Trump administration's campaign to economically pressure Tehran six months into the US-Israel war with Iran, which has pushed energy prices higher worldwide.
Bessent, who last month announced an "economic onslaught" against Iran's financial links around the world, has said Washington is seeking to force Tehran back to the negotiating table.
Last week, Washington moved to impose Patriot Act curbs on Egyptian lender Banque Misr's branches in the United Arab Emirates from US dollar transactions over their dealings with Iran. But the action fell short of full OFAC sanctions on the institution that did not affect Misr's head office or branches elsewhere.
In an interview with Reuters on Sunday, Bessent said the Treasury Department was likely to roll out new secondary sanctions every week, initially focusing on banks, as part of a broader campaign to intensify economic pressure on Iran.
