TL;DR:
- U.S. prosecutors are investigating whether Binance allowed transactions that may have violated sanctions on Iran, with offices in Manhattan and Washington involved.
- The inquiry is examining whether compliance controls adopted after Binance’s 2023 guilty plea and $4.3 billion settlement worked as intended.
- Binance says it has zero tolerance for sanctions violations and cooperates with authorities, while the transactions under review remain undisclosed and no charges have been filed.
Binance is facing renewed U.S. scrutiny as federal prosecutors examine whether the exchange knowingly allowed transactions that may have violated sanctions on Iran. A Bloomberg report said the Manhattan U.S. attorney’s office is handling the inquiry with support from the Justice Department’s criminal division in Washington. The investigation is focused on whether Binance’s controls failed to stop prohibited Iran-linked activity despite earlier compliance commitments. The transactions under review have not been publicly detailed, and the investigation could conclude without charges.
Binance Faces Fresh Questions Over Sanctions Controls
The probe arrives nearly three years after Binance pleaded guilty to violating U.S. banking and sanctions laws, paid $4.3 billion and accepted two corporate monitors. Authorities are now examining whether the compliance measures implemented after that settlement were effective in practice. That makes the current inquiry especially significant because prosecutors are not only looking at specific transactions, but also at whether Binance’s post-2023 compliance framework worked as intended. Binance says it maintains a zero-tolerance policy for sanctions violations and cooperates with law enforcement, rejecting suggestions that it knowingly facilitated prohibited activity.
Iran-linked flows have already drawn scrutiny around Binance. Earlier allegations claimed investigators identified more than $1 billion tied to entities connected with Iran before being dismissed. Binance disputed that account, saying the funds neither originated nor terminated on its platform and that only a smaller amount ultimately reached Iran-linked wallets after multiple transaction hops. The competing accounts have kept Binance’s sanctions controls under pressure even as the exchange argues its compliance processes remain effective. Crypto Economy previously covered the exchange’s response to Iran-related compliance allegations and its broader compliance overhaul.
The investigation comes as U.S. authorities scrutinize assets tied to sanctioned jurisdictions and cross-border financial networks. Prosecutors sought forfeiture of $61 million they say came from Iranian black-market oil sales and was laundered through Binance, although the exchange was not accused of wrongdoing in that case. For Binance, the immediate risk is not a confirmed violation but the possibility that prosecutors conclude its safeguards failed despite controls imposed after its settlement. Until the inquiry is resolved, the central question is whether investigators find evidence that prohibited trades were knowingly allowed or determine that Binance met its legal obligations.
