U.S. federal prosecutors are investigating whether Binance Holdings knowingly allowed trading that violated American sanctions on Iran, according to a Bloomberg report published September 22. The reported investigation is being handled by the Manhattan U.S. Attorney’s Office, with the Justice Department’s Criminal Division in Washington also involved. No new charges against Binance have been announced, and the Justice Department has not publicly confirmed the investigation.
According to the Bloomberg Law report, authorities are examining whether Binance knowingly permitted certain Iran-related trading rather than simply whether sanctioned exposure reached the platform. That distinction places knowledge and compliance decisions at the center of the reported criminal inquiry, although the evidence prosecutors are reviewing and the specific transactions under examination have not been publicly disclosed.
2023 Guilty Plea Creates a Key Compliance Baseline
The inquiry comes nearly three years after Binance pleaded guilty to violations of the Bank Secrecy Act, failure to register as a money transmitting business and violations of the International Emergency Economic Powers Act. Binance agreed to $4.316 billion in criminal penalties and forfeiture while committing to strengthen its anti-money-laundering and sanctions compliance systems. The DOJ said the exchange had willfully caused more than $898 million in trades between U.S. users and users ordinarily resident in Iran between January 2018 and May 2022.
Binance says its compliance operation has expanded substantially since that settlement. The company reported in 2026 that more than 1,500 employees and service providers, approximately one quarter of its global workforce, work in compliance-related roles. Those figures describe Binance’s stated investment in remediation, but they do not resolve whether controls performed adequately in the transactions now reportedly under investigation.
Recent Iran-related enforcement provides additional context without establishing wrongdoing by Binance. On September 14, Manhattan prosecutors sought forfeiture of approximately $61 million in cryptocurrency allegedly derived from black-market Iranian oil sales. The government alleged that Blessed Trust and Hexa Whale used Binance accounts within a network that helped move proceeds linked to Iran and the IRGC, but the forfeiture complaint targets the assets and alleged laundering network rather than charging Binance.
Reported Probe Tests Binance’s Post-Settlement Controls
The reported investigation therefore raises a narrower question than whether suspicious Iran-linked funds ever touched Binance. Prosecutors would need to establish the relevant conduct and knowledge under the applicable sanctions laws before any criminal liability could be determined. Bloomberg reports that investigators are specifically scrutinizing whether Binance knowingly allowed prohibited trading, while Reuters said it could not independently verify the report.
Binance has publicly emphasized its sanctions controls and says specialized compliance teams cover sanctions, terrorist financing and financial-crime investigations. The company’s position is that its compliance decisions are based on legal requirements and established procedures rather than commercial considerations, while the reported federal inquiry is examining whether those controls worked as intended in the activity under review.
The current stage remains investigative. A federal investigation does not establish that Binance committed a new sanctions violation, and no indictment, criminal complaint or settlement tied to the reported 2026 probe has been announced. The most important next milestone will be whether the Justice Department closes the inquiry, seeks charges or produces court filings that identify the transactions and internal compliance decisions under scrutiny.
