The U.S. Department of Justice is examining if Binance breached the conditions of its $4.3 billion 2023 settlement while investigating alleged violations of Iran sanctions. Tysen Duva, head of the DOJ’s Criminal Division, confirmed the review on October 9, noting that specific incidents under scrutiny have not been publicly detailed.

Three cases drive the inquiry: accounts linked to Iranian financier Babak Zanjani processed nearly $850 million; a September forfeiture filing alleges Chinese firms Blessed Trust and Hexa Whale laundered $61 million from Iranian oil sales within a network moving over $1.5 billion; and prosecutors question if Binance knowingly facilitated trades violating US rules. Internal documents indicate at least $67 million flowed from Zanjani-linked accounts to wallets associated with the Islamic Revolutionary Guard Corps. Binance stated it blocked relevant accounts starting late 2025 and removed others by May 2026.
