Binance Faces U.S. Scrutiny Over Possible Iran Sanctions Violations

U.S. federal prosecutors are investigating whether cryptocurrency exchange Binance violated U.S. sanctions on Iran by failing to prevent certain trading activity on its platform, according to a Bloomberg News report cited by Reuters. The investigation is reportedly being led by the Manhattan U.S. Attorney’s Office, with the U.S. Department of Justice’s criminal division also involved.

Authorities are examining whether Binance knowingly allowed transactions involving Iran despite applicable sanctions restrictions. No findings of wrongdoing have been announced, and the investigation remains ongoing.

The development highlights the compliance challenges cryptoasset businesses face when screening customers and monitoring transactions across jurisdictions subject to financial sanctions. Effective controls must identify sanctioned persons and entities while also detecting transaction patterns that may indicate attempts to circumvent geographic or financial restrictions.

Binance said it maintains a zero-tolerance approach to sanctions violations and cooperates fully with law enforcement. The DOJ and Manhattan U.S. Attorney’s Office did not comment immediately to Reuters.

The exchange has previously faced significant U.S. regulatory scrutiny. In 2023, Binance and its then-chief executive Changpeng Zhao reached a $4.3 billion settlement with U.S. authorities, with Zhao pleading guilty to violating U.S. anti-money laundering requirements.

The latest investigation comes amid increased U.S. sanctions activity targeting Iranian financial networks. Earlier in September, the U.S. sanctioned firms and individuals accused of supporting Hezbollah and other Iranian-linked networks. Separately, U.S. authorities recently targeted an Iranian cryptocurrency exchange over alleged sanctions evasion activity, underscoring the growing focus on digital assets as a potential channel for moving restricted funds.

Compliance takeaway

For cryptoasset firms, the case reinforces the importance of continuous sanctions screening, transaction monitoring, customer risk assessment and controls capable of identifying attempts to bypass geographic restrictions. Compliance teams should also regularly test whether controls remain effective as sanctions lists, typologies and risk exposures change.
