US imposes sanctions on Turkish bank, prompting legal threat

The United States Treasury Department has imposed sanctions on a Turkish bank and its subsidiaries over alleged ties to Iran, as Washington seeks to economically isolate Tehran.

The Treasury Department accused Golden Global Yatirim Bankasi Anonim Sirketi (Golden Global Bank) on Friday of facilitating “tens of millions of dollars’ worth of transactions for the Islamic Revolutionary Guard Corps-Qods Force” and providing the Iranian government with banking access to move its funds internationally.

Washington alleged the bank “was established for the purpose of enabling Iran’s rahbar network [shadow banking system] to transfer oil revenues from China to Turkey” using gold and cash.

Golden Global Bank responded on Friday, saying it fulfilled all local and international banking compliance rules and would take legal action against the US-imposed sanctions.

There are no transactions conducted by Golden Global Bank that could substantiate the claims made by the US, the bank said in a news release.

“We will exercise all our rights of objection and legal recourse in the most effective manner and will take the necessary actions at the earliest against these allegations and the decision,” the Turkish bank added.

“Financial institutions continue to find out the hard way that we are serious about Operation Economic Outcast,” said Secretary of the Treasury Scott Bessent in a statement published by the department on Friday.

The sanctions place the bank and its two subsidiaries on the US Office of Foreign Assets Control (OFAC)’s Specially Designated Nationals list, cutting off access to the US financial system.

The bank said individuals and entities named in the OFAC decision “have never been and are not currently customers” of Golden Global.

US Ambassador to Turkiye Tom Barrack said on Saturday that it would be a mistake for Turkish officials “to read [the US’s] narrow measure as a judgement upon Turkiye”.

“The health of the Turkish financial system is not in question; the conduct of one institution was,” Barrack said on X.

Last week, the US took steps towards severing the UAE operations of Egypt’s second-largest bank from financial access after accusing it of processing transactions for companies linked to Iran’s shadow-banking system.

Bessent said on Tuesday on the sidelines of a G20 summit that Washington would likely announce a bank sanction this week and another next week, as it ramps up its economic campaign against Tehran.
