US federal prosecutors are investigating whether Binance violated sanctions on Iran by failing to stop certain trading on its platform, according to Bloomberg Law, which cited people familiar with the matter, and Reuters, which confirmed the account with its own source.

The inquiry is led by the Manhattan US attorney’s office, with the Justice Department’s criminal division in Washington also involved, and it examines whether the crypto exchange knowingly allowed the trading. Both offices declined to comment; Binance said it has a “zero-tolerance” approach to sanctions violations and that it cooperates with law enforcement. On September 14, 2026, the same office sought the forfeiture of about US$ 61 million in crypto that, according to prosecutors, came from black-market Iranian oil sales, in an action filed against the assets, with no accusation against the exchange. Binance paid a US$ 4.3 billion penalty in 2023 over money-laundering and sanctions controls, when the Justice Department calculated that more than US$ 898 million in trades had flowed between US users and users ordinarily resident in Iran from January 2018 through May 2022.
