United States federal prosecutors are investigating whether Binance, the world’s largest crypto exchange, knowingly allowed trading that violated American sanctions on Iran, according to a Bloomberg report published Tuesday, September 22 — and the probe lands nearly three years after the exchange’s record 4.3 billion USD criminal settlement.

The Hook: A New DOJ Probe Lands on Binance’s Doorstep
According to Bloomberg, the Manhattan U.S. Attorney’s Office is leading the inquiry, with the Justice Department’s Criminal Division in Washington also participating. Prosecutors are reportedly examining Binance’s compliance controls — the systems that are supposed to block banned transactions — and whether the exchange knew about the transactions under review. Reuters said it had not independently verified Bloomberg’s account, and the Justice Department declined to comment.
Binance pushed back firmly. The exchange said it maintains a zero-tolerance policy for sanctions violations and stated: “We fully cooperate with law enforcement, and we remain committed to rooting out and shutting down bad actors.” The Manhattan U.S. Attorney’s Office was not immediately available for comment outside normal business hours.
For regular investors, the headline question is simple: could this hit the crypto market? Binance remains the industry’s single largest exchange by trading volume, so any serious legal threat against it tends to ripple across prices. Bitcoin is currently trading around 86,000 USD, up nearly 6% over the past day, with Ethereum near 2,751 USD and Solana around 117 USD — a market that, so far, is shrugging off the news.
The Evidence: A 61 Million USD Forfeiture Case and a 1.5 Billion USD Network
The Bloomberg report did not come out of nowhere. On September 14, prosecutors in the Southern District of New York filed a civil forfeiture complaint seeking all USDT held in 10 cryptocurrency addresses on the TRON network — assets valued at approximately 61 million USD. The filing alleges the funds represent proceeds from black-market Iranian crude oil and petroleum sales, money intended to finance Iranian government and military bodies, including the Islamic Revolutionary Guard Corps.
The complaint names two Chinese companies — Blessed Trust and Hexa Whale — as having used Binance trading accounts while handling proceeds connected to Iranian oil sales. Prosecutors alleged that a broader network of crypto actors laundered more than 1.5 billion USD in illicit oil proceeds. The case number is 1:26-cv-08010, and the Justice Department notes its allegations remain unproven until a court enters judgment. Importantly, the complaint does not accuse Binance itself of wrongdoing in that proceeding.
Court records describe a striking custody arrangement: Tether would burn the targeted USDT tokens and issue replacement tokens of equal value for transfer into U.S. government custody — a bit like a bank voiding marked bills and printing clean replacements for the authorities.
The Core Conflict: Binance’s Timeline vs. the Investigators’
Binance has told its own version of events. In a March 6 response to a Senate inquiry, the company described parts of earlier reporting as “demonstrably false, unsupported by credible evidence, and defamatory in several material respects.” It said law enforcement first contacted it in April 2025 about transactions with possible terrorism-financing connections, that it handed over records for Hexa Whale in June 2025, and that it removed Hexa Whale from the platform on August 13, 2025. A source-of-funds review led it to offboard Blessed Trust in January 2026.
The exchange also disclosed figures from its internal review: approximately 126.1 million USD eventually reached wallets linked to Iran after multiple blockchain hops, with as much as 24.1 million USD reaching IRGC-related wallets. Binance maintains that, to its knowledge, no Binance account transacted directly with an Iran-based entity — and those figures are the company’s own account, not court findings.
The tension is clear: investigators reportedly want to know whether Binance knew what was moving through its pipes, while Binance argues it detected, reported, and offboarded the problem accounts as soon as the trail became visible. Scrutiny of the exchange’s Iran-linked controls had already surfaced in March, when Senators Elizabeth Warren, Chris Van Hollen and Ruben Gallego planned congressional oversight of a reported DOJ investigation.
Market Implications: The 4.3 Billion USD Shadow
This is not Binance’s first encounter with U.S. prosecutors. In November 2023, the exchange pleaded guilty to violations involving the Bank Secrecy Act, operating an unregistered money-transmitting business, and violating the International Emergency Economic Powers Act — accepting a criminal financial penalty of 4.316 billion USD. That resolution installed independent monitors and forced a compliance overhaul.
A repeat sanctions problem while under that level of supervision would carry serious consequences — potentially including steeper penalties or tighter restrictions on the exchange’s operations. Binance points to its current posture: more than 1,500 compliance staff (roughly a quarter of its global workforce), over 71,000 law-enforcement requests processed during 2025, and a claimed 97.3% drop in exposure to four major Iranian crypto exchanges — from 4.19 million USD down to 110,000 USD over two years.
Why should a regular investor care? Because exchange risk is market risk. In November 2023, when the guilty plea landed, crypto prices dipped before recovering. If this probe escalates into charges, expect short-term volatility and renewed political pressure on the whole industry — particularly on the stablecoin and cross-border payment corridors the forfeiture case highlights. If it fades, the market will likely move on quickly, as it has after past Binance headlines.
The Verdict: Watch the Court Filings, Not the Headlines
For now, this is a reported investigation, not a charge. The known, documented facts are the September 14 forfeiture complaint and Binance’s published congressional response. Everything else rests on unnamed sources. The practical takeaway for investors: nothing here requires action on your portfolio today, but it is a reminder that the largest on-ramps in crypto still carry regulatory luggage — and that sanctions compliance, not price action, may be the story that decides Binance’s next chapter.

3 years after a 4.3 billion dollar plea and they still might have been running Iran-linked accounts. some things never change lol
cz took the exit in 2023 but the entity kept the same incentives. nobody should be surprised
The 2023 settlement already forced compliance monitors onto Binance. If this probe is real, those monitors missed whatever DOJ is now chasing, and that is the actual story here.
agreed, though bloomberg says knowingly, which is a much higher bar than sloppy kyc checks. that one word does a lot of work
4.3 billion settlement and three years later we are back at the same question. at some point you have to wonder if any fine actually changes behavior
Manhattan US Attorney running it means this is not a routine inquiry. If the compliance controls knowingly failed, that monitorship deal gets messy fast.
@Rune also note reuters couldnt verify any of it. bloomberg single source DOJ stories have burned people before, holding judgment
