The probe focuses on billions of dollars in money movements between firms overseen by oil tycoon Hossein Shamkhani, the son of a top adviser to Supreme Leader Ali Khamenei, Bloomberg said.
According to the report, the probe has drawn on information from insiders within Shamkhani’s business network and from Wall Street banks that had relationships with entities linked to him.
The main target of the investigation is Shamkhani, rather than the banks, Bloomberg said.
JPMorgan Chase & Co., ABN Amro Bank NV, Marex Group Plc, Standard Chartered PLC, Emirates NBD PJSC and National Bank of Fujairah PJSC are among the institutions under review, the report said citing several people familiar with the probe.
Bloomberg said spokespeople for the Justice Department, JPMorgan, ABN Amro, Marex and Standard Chartered declined to comment. National Bank of Fujairah said it is “not under investigation by the US Department of Justice,” while Emirates NBD said it has not received any communication from US authorities.
