The U.S. Treasury Department announced sanctions against Turkey’s Golden Global Bank and its subsidiaries, accusing the financial institution of facilitating transactions for Iran’s Revolutionary Guard, specifically its Quds Force. This move marks the second bank targeted under the Trump administration’s "Operation Economic Outcast," a campaign aimed at isolating Tehran by cutting off its financial lifelines. Treasury Secretary Scott Bessent emphasized the hope that no additional banks will be sanctioned, but indicated future actions depend on the international community’s response to curbing support for the Iranian regime.

Golden Global Bank, Turkey’s 35th-largest bank with assets around $517 million in today’s dollars, allegedly provided critical correspondent banking services that enabled the Iranian regime to transfer oil revenues from China to Turkey. These funds were then converted into cash and gold through networks linked to Iran’s shadow financial apparatus. The Treasury described the bank as knowingly offering services to illicit Iranian financial institutions, complicating U.S. efforts to stifle the regime’s ability to fund military operations abroad.

Despite these sanctions, the U.S. has yet to take concrete measures against China, which remains Iran’s largest trading partner and top oil buyer. While Bessent insisted that China is not exempt from potential penalties, he downplayed the notion that the sanctions campaign’s success hinges on Beijing’s participation. This stance comes ahead of an anticipated summit between President Donald Trump and Chinese President Xi Jinping later this month, as U.S.-China relations remain fragile and complex.

President Trump has promoted "Operation Economic Outcast" as an unprecedented economic offensive against Iran, labeling it an "economic D-Day." However, tangible enforcement actions beyond a few banks, including a UAE subsidiary of an Egyptian bank targeted last week, have been limited so far. The European Union has expressed formal support for the operation, joining the international effort to intensify sanctions and pressure the Iranian leadership through coordinated financial isolation.
