Binance faces U.S. Senate investigation over $1.7B in sanctioned transactions

Binance faces U.S. Senate investigation over $1.7B in sanctioned transactions
Binance faces new U.S. review

​US Sen. Richard Blumenthal has launched an official investigation into Binance following a Feb. 13 report by Fortune. The report alleged that the exchange processed roughly $1.7 billion in transactions linked to sanctioned Iranian entities and vessels associated with Russias shadow fleet.

The investigation focuses on the platforms internal compliance system and its response to identified risks, CoinGape reported. Blumenthal requested that Binance CEO Richard Teng provide documents and data related to the disputed transactions, including internal correspondence and compliance reports. The senator also sought details on how the company responded to internal warnings about potential sanctions violations.

The move increases pressure on the worlds largest crypto exchange, which has already faced intense scrutiny from US regulators following a multibillion-dollar settlement with US authorities in 2023. The new review could examine sanctions monitoring procedures and the companys dealings with international counterparties. If additional violations are identified, the matter could be referred to the US Department of Justice or the Treasury Departments Financial Crimes Enforcement Network. That could result in new fines, stricter compliance requirements or expanded conditions under existing agreements with US regulators.

Scope of the review and details of the allegations

According to the Fortune report, the disputed transactions were processed during the period when international sanctions were in effect. The publication cited internal documents and anonymous sources familiar with the work of the compliance team.

The report also claimed that at least five compliance employees were dismissed after identifying suspicious transactions. A statement cited in the article said: “After an internal review and based on advice from qualified legal counsel, we found no evidence that Binance violated applicable sanctions laws in connection with the activity mentioned.”

Blumenthal aims to determine what warning signals were recorded by the internal investigative team and whether appropriate corrective measures were taken. Additional information has also been requested regarding incidents referenced in a Forbes report. If necessary, the investigation could escalate into public Senate hearings.

Binance response and market reaction

Binance publicly denied the allegations of sanctions violations. The company said it has significantly upgraded its compliance framework over the past two years and strengthened transaction monitoring procedures.

According to Binance, the volume of trading associated with sanctions-related risks declined by 96.8% between January 2024 and July 2025. The share of such transactions fell to 0.009% of total trading volume, compared with 0.284% previously. Binance presented these figures as evidence of improvements in its internal control systems.

Following publication of the report, the market reaction was notable. BNB fell about 3% in the first hours after the report was released on February 13, Coinpaper reported. Analysts observed increased volatility in spot BTC and BNB markets as investors reassessed regulatory risks. At the same time, any additional regulatory restrictions on the exchange could negatively affect trading volumes, liquidity and capital flows across the crypto market.

Sanctions risks and pressure on crypto infrastructure

Between 2023 and 2025, major crypto platforms significantly increased spending on AML and sanctions monitoring following record fines and settlements with US regulators. The industry has allocated hundreds of millions of dollars to strengthen internal control systems, automated transaction analysis and counterparty screening.

Growing geopolitical restrictions have intensified requirements for transparency in cross-border transactions and customer identification. Even a small share of transactions potentially subject to sanctions can result in substantial fines, license restrictions or additional oversight measures.

For institutional investors, the outcome of the investigation is important in assessing infrastructure stability and counterparty risk. Tighter sanctions enforcement marks a new phase of maturity in the crypto industry, where compliance quality is becoming a key competitive factor.
