Binance Pushes Back on Sen. Blumenthal’s Iran Sanctions Probe
On March 6, 2026, Binance issued a strongly worded open letter rejecting allegations raised by Senator Richard Blumenthal (D-CT) in a February 2026 inquiry letter. The senator had accused Binance of being a “repeat offender” of U.S. sanctions, citing investigative reporting from The New York Times, The Wall Street Journal, and Fortune that suggested the exchange facilitated Iranian access to crypto services through partners Hexa Whale and Blessed Trust.
Binance’s response, addressed directly to Blumenthal, states:
“The recent reporting on which your inquiry relies, however, is demonstrably false, unsupported by credible evidence, and defamatory in several material respects.”
The exchange claims it conducted a proactive internal investigation after receiving law enforcement inquiries, identified indirect exposure to Iran-linked wallet addresses via the two Hong Kong-based service providers, and subsequently terminated those partnerships.
Key Claims from Binance’s Letter
- No direct transactions with Iran-based entities occurred on Binance accounts, to their knowledge.
- Exposure to wallets allegedly involved in illicit activity dropped 97% (from 0.284% to 0.009% of total exchange volume) thanks to advanced compliance tools.
- Exposure to four major Iranian crypto exchanges fell 97.3% in two years, from $4.19M to $110,000.
- Binance uses more than 25 advanced tools for sanctions screening, transaction monitoring, behavioral analytics, and due diligence.
Background of the Allegations
Media reports in late February 2026 alleged:
- Internal Binance investigators identified >1,500 accounts accessed from Iran.
- Roughly $1.7B flowed from two Binance accounts to Iran-linked entities, including wallets tied to the Islamic Revolutionary Guard Corps (IRGC), a U.S.-designated terrorist organization.
- Hexa Whale Trading moved approximately $500M in USDT to IRGC-linked addresses.
- Several senior compliance officials reportedly left or were suspended after the investigation surfaced.
These stories came years after Binance and former CEO Changpeng Zhao pleaded guilty in November 2023 to sanctions violations and failing to register as a money transmitting business, resulting in $4.3B in penalties, corporate compliance monitoring, and Zhao’s four-month prison sentence (later pardoned by President Trump).
Current Status & Next Steps
Binance has not commented further on the ongoing litigation or the Blumenthal inquiry. The letter emphasizes the company’s commitment to compliance and invites continued dialogue with lawmakers.
The situation remains fluid:
- No public response from Sen. Blumenthal or his committee as of March 6, 2026.
- No indication of new enforcement action from OFAC or the Department of Justice.
- Binance continues to operate globally while maintaining that its compliance program is “consistently growing stronger.”
