Senate Democrats are pressing federal authorities to investigate whether Binance is complying with U.S. sanctions laws, just two years after the exchange agreed to more than $4 billion in penalties tied to illicit finance failures. The renewed scrutiny signals that political pressure on the world’s largest crypto exchange remains far from resolved.
On Friday, Sen. Chris Van Hollen and 10 other Democrats sent a letter to Attorney General Pam Bondi and Treasury Secretary Scott Bessent urging a formal review of Binance’s sanctions compliance controls. The request follows media reports alleging that two Binance partners, Hexa Whale and Blessed Trust, acted as intermediaries in transactions linked to Iranian government entities. According to those reports, some individuals involved in internal investigations were disciplined or dismissed, claims the company disputes.
Is Binance Fully Meeting Its Sanctions Obligations?
The inquiry arrives at a sensitive moment for the exchange. In 2023, Binance pleaded guilty to failing to register as a money transmitting business and breaching sanctions laws, agreeing to sweeping compliance reforms and billions in penalties. Former CEO Changpeng Zhao was charged and later served four months in prison. Lawmakers now argue that recent reporting raises questions about whether the company has upheld its commitments under that settlement.
In their letter, the senators wrote, “We urge you to conduct a prompt, comprehensive review of sanctions compliance on the platform to ensure that it is not once again violating the law and threatening U.S. national security.”
Earlier this week, Sen. Richard Blumenthal, a senior Democrat on a Homeland Security investigative panel, separately contacted Binance CEO Richard Teng over similar concerns. Binance pushed back, with a spokesperson stating the allegations are based on false reporting and asserting that the company detected and reported suspicious activity, evidence, it says, that its controls are functioning.
The lawmakers have requested a response from federal officials by March 13. Whether regulators escalate enforcement or determine that Binance’s monitoring systems are sufficient could shape how aggressively Washington approaches offshore crypto platforms next. The next catalyst will be the Justice Department and Treasury’s formal reply—and any indication of a new probe.
