Senator Richard Blumenthal has given Binance until April 14 to explain a massive gap between its reported Iranian transaction volumes and what media investigations uncovered.
Richard Teng, the co-CEO who stepped in to steer Binance through its post-Changpeng Zhao compliance reckoning, just received a letter he cannot afford to ignore. Senator Richard Blumenthal, the Connecticut Democrat who sits on the Senate Permanent Subcommittee on Investigations, fired off a follow-up inquiry on April 1 demanding Binance explain what appears to be a staggering discrepancy in how it characterized transactions linked to Iran. The company previously told the Subcommittee that direct transactions with four major Iranian exchanges totaled just $110,000. Fortune and The New York Times traced roughly $1.7 billion in flows from Binance-linked accounts to entities with Iranian ties, a number that makes Binance's original disclosure look either incompetent or deceptive.
Blumenthal's letter pulls no punches. He wrote that he is concerned Binance may have provided "misrepresentations or misleading information" to the Subcommittee and the public. This is not a routine congressional follow-up. When a senator uses language like that, it signals potential legal exposure beyond regulatory fines. Providing false or misleading statements to Congress carries criminal liability, and Blumenthal clearly wants Binance to understand the gravity of the situation.
The scope of the document request is remarkably specific, which tells you Blumenthal's team has been building a detailed case. The senator wants wallet addresses associated with Iran-linked accounts, a full year-over-year accounting of all transactions between Binance and known Iranian exchanges, and a complete explanation of the methodology Binance used to arrive at that $110,000 figure. He is essentially asking Binance to show its math, which suggests he already suspects the number was either cherry-picked or calculated in a way that excluded significant transaction volumes.
Beyond the raw transaction data, Blumenthal is probing whether Binance has weakened its internal compliance infrastructure since the start of 2025. He asked specifically whether the exchange has removed or relaxed any detection, screening, freezing, or reporting mechanisms, including tools designed to catch illicit indirect transfers. He also wants to know whether Binance has ever declined to investigate accounts tied to individuals inside Iran who were using VPNs or "drop accounts," which are KYC-verified accounts that have been bought, shared, or stolen. These are the exact compliance blind spots that have haunted Binance for years.
A Pattern of Delayed Action
Perhaps the most damaging section of Blumenthal's letter deals with Binance's response times to law enforcement warnings about terrorist financing. According to the senator, Binance took two months to respond to law enforcement regarding alleged terrorist financing by entities including Hexa Whale, and another two months to remove an implicated shell entity. He also alleges it took at least five months for Binance to cut ties with Blessed Trust as a vendor after being warned about its role in suspected terrorist financing.
Then there is the matter of internal account tags. Blumenthal wrote that Binance appeared to label certain accounts with tags like "Don't block. Internal accounts," which should have triggered heightened scrutiny but instead seemed to shield those accounts from enforcement. If accurate, this suggests a compliance culture that was not merely understaffed or slow, but actively working against its own safeguards.
Blumenthal also asked whether Binance has ever disciplined compliance staff who raised concerns internally or shared information with law enforcement, noting reports that the company dismissed personnel for "unauthorized disclosure." That question alone should make any current or prospective Binance compliance officer think carefully about the environment they are working in.
What This Means for the Market
Binance is already operating under a court-appointed monitor as part of its $4.3 billion settlement with US authorities in late 2023, an agreement that also saw Zhao step down as CEO and serve a prison sentence. This Senate inquiry runs on a parallel track but adds a distinct political dimension. Regulators negotiate settlements. Senators build public records that can drive new legislation, and Blumenthal has a history of pushing aggressive consumer protection and corporate accountability measures.
For crypto investors and entrepreneurs, the immediate practical concern is operational risk. Binance remains the world's largest exchange by trading volume, and any disruption, whether through further regulatory action, forced compliance overhauls, or reputational damage, would ripple across the market. The broader concern is legislative. Each revelation about compliance failures at major exchanges strengthens the hand of lawmakers who want stricter rules for the entire industry, not just the bad actors.
The deadline is April 14. Watch what Binance produces, and more importantly, what Blumenthal says after he reviews it. If the documents do not satisfy the Subcommittee, expect a public hearing, and expect it to be consequential.
