DOJ probes Binance over alleged Iran sanctions breaches

Key points

• The US Department of Justice and the Manhattan US Attorney’s Office are investigating whether Binance failed to block trading linked to sanctioned Iranian entities, according to Bloomberg and Reuters.
• Binance spokesperson Ross O’Leary stated the company maintains a 'zero-tolerance policy' for sanctions violations and is cooperating with law enforcement.
• The investigation follows a civil forfeiture claim filed in September seeking $61 million in proceeds from black-market Iranian oil sales, which the DOJ alleged were facilitated by Chinese firms Blessed Trust and Hexa Whale via Binance.
• In February 2026, reports indicated Binance suspended or fired at least four compliance investigators who raised concerns about $1.7 billion in payments to wallets linked to Iranian-backed entities, including Yemen’s Houthi rebels.
• Former CEO Changpeng Zhao was pardoned by President Trump in October 2025 after pleading guilty to anti-money laundering charges in a 2023 case that resulted in a $4.3 billion fine for Binance.

Background

This investigation occurs against a backdrop of escalating US-Iran tensions, including an ongoing war that began in February 2026 and the near-total closure of the Strait of Hormuz. The US Treasury has recently intensified its 'Operation Economic Outcast' campaign, designating Iranian digital asset exchanges like BitBank to disrupt regime financing. Chainalysis estimated that crypto sent to sanctioned entities surged nearly 700% in 2025, reaching $104 billion, highlighting the growing use of cryptocurrency for sanctions evasion.

How outlets are covering it

Gizmodo and Bitcoin Magazine emphasize the criminal investigation by the DOJ and the historical context of Binance’s 2023 compliance failures and subsequent pardon of its founder. CoinDesk and VOA focus on the broader Treasury-led sanctions campaign, specifically highlighting the designation of BitBank and the use of Bitcoin to pay 'tolls' for passage through the Strait of Hormuz. While all sources agree on the active federal scrutiny, they differ in emphasis: some focus on the potential criminal liability for Binance, while others highlight the specific mechanisms of Iranian sanctions evasion through crypto exchanges.

Why it matters

The probe signals a significant shift in how US authorities are holding major cryptocurrency exchanges accountable for sanctions compliance. If charges are filed, it could set a precedent for stricter enforcement against global exchanges and intensify the crackdown on crypto-based sanctions evasion, potentially affecting the broader crypto market's regulatory landscape.

What to watch

The DOJ investigation may result in criminal charges or a declination. Binance has stated it is cooperating, but the outcome will depend on the evidence regarding the $1.7 billion in payments and the $61 million forfeiture claim. The broader Treasury sanctions campaign is expected to continue, with potential secondary sanctions on foreign institutions that facilitate Iranian crypto transactions.
