Binance Iran crypto allegations returned on May 22 after The Wall Street Journal alleged that an Iran-linked payments network tied to Babak Morteza Zanjani moved roughly $850 million through a single account on the exchange over about two years. Richard Teng, Binance’s chief executive, rejected the report, saying the transactions cited by the paper happened before the relevant parties were sanctioned and that the company had already reviewed the matter before the Journal contacted it.
The immediate fight is about sourcing, timing and reputation. The larger pressure point is whether the exchange can prove that its post-settlement control system spots sanctions risk before lawmakers, prosecutors or blockchain intelligence firms do.
Teng’s Defense Turns on Timing
Teng’s public response has three parts. He says the platform did not permit transactions with sanctioned individuals, that the activity cited by the Journal predates the designations at issue, and that the company gave the newspaper information that did not appear in the final story. That defense is narrow by design. It does not ask readers to ignore Iran-linked flows; it asks them to separate platform activity from sanction status at the moment of each transaction.
That distinction matters in sanctions law because a transfer can look toxic in hindsight while sitting outside a particular prohibition at the time it cleared. It also creates a heavy evidence burden for the exchange. Account opening records, device data, wallet tags, internal alerts and designation dates would have to line up cleanly.
There is a second problem. The Journal’s new allegation follows earlier reporting this year that already pulled the company into congressional scrutiny. Teng can win a single factual dispute and still leave regulators asking why Iran-linked patterns keep landing in the same venue.
The WSJ’s reporting continues to contain fundamental inaccuracies about the facts and Binance’s commitment to a strong compliance framework.
Teng wrote that on X on May 22. His wording signals a company preparing for a document fight, not only a public relations fight.
The Monitor Is the Shadow Regulator
The reason this story carries more weight than an ordinary exchange denial is the company’s existing settlement history. In the Justice Department’s Binance case page, prosecutors say the exchange pleaded guilty in November 2023 to Bank Secrecy Act violations, failure to register as a money transmitting business and violating the International Emergency Economic Powers Act.
The financial penalty was $4.316 billion, and the remedial package included compliance enhancement, remediation and an independent monitor. Treasury’s own settlement release added another layer: FinCEN imposed a $3.4 billion civil money penalty, while OFAC assessed a $968 million settlement and said the monitor would keep access to books, records and systems for five years through the Treasury settlements with Binance.
| Pressure Point | Core Fact | Why It Matters Now |
|---|---|---|
| DOJ plea | Guilty plea tied to anti-money laundering and sanctions failures | Creates a baseline for judging later controls |
| FinCEN and OFAC settlements | Five-year monitor access to systems and records | Gives regulators a live compliance window |
| Senate inquiry | Records sought on Iran and Russian sanctions evasion | Turns press allegations into document demands |
| May 22 report | Alleged Zanjani-linked account activity | Tests whether remediation caught repeat risk |
That makes the monitor the quiet center of the dispute. A monitor does not need to prove the Journal’s article. A monitor needs to know whether the exchange’s systems worked as promised after the plea.
Zanjani Makes the Case Larger Than One Account
Zanjani is not a random trader in this story. In January, the U.S. Treasury Department described him as an Iranian businessman and sanctions evader who had been active in hospitality, transportation, technology, financial services and oil exports. Treasury also said he had previously embezzled billions of dollars in Iranian oil revenue and later backed projects supporting Iran’s Islamic Revolutionary Guard Corps (IRGC, Iran’s powerful military and security force).
The same Treasury action on Zanjani and linked exchanges designated Zedcex Exchange Ltd. and Zedxion Exchange Ltd., two UK-registered digital asset exchanges connected to him. Treasury said Zedcex had processed over $94 billion in transactions since registration in August 2022 and that wallets attributed to Zedcex and Zedxion processed funds for IRGC-linked wallets.
Blockchain firm Chainalysis added useful context in its analysis of the Iranian-linked exchange designations. It noted that Zanjani had been designated by OFAC in 2013, delisted in 2016 under Joint Comprehensive Plan of Action related removals, then designated again in January. That history is exactly why the timing dispute is so technical.
For the exchange, the best version of the defense is chronological. For investigators, the more uncomfortable question is operational: whether accounts, counterparties and wallet clusters tied to a known sanctions-evasion figure should have triggered higher concern before formal action landed.
Stablecoins Have Become the Sanctions Rail
The Iran piece also fits a larger movement in illicit finance. Stablecoins, especially dollar-linked tokens, now do some of the work that correspondent banks and cash couriers once did. They are fast, liquid and easy to move across borders. Those features help ordinary users. They also help sanctioned networks.
- Over $7.78 billion: Chainalysis estimated the observed Iranian crypto system reached that level in 2025.
- Just over $580 million: TRM Labs estimated illicit Iranian crypto volume in 2025, about 5.9 percent of observed activity.
- Close to $1 billion: TRM said Zedcex processed that amount in IRGC-associated transactions from 2023 to 2025.
TRM’s Crypto Crime Report on illicit crypto trends said Iran’s illicit activity was heavily concentrated in stablecoins, particularly USDT (Tether, a dollar-pegged token widely used for settlement). It also said Zedcex activity was largely USDT on the TRON blockchain, where low fees and broker acceptance make high-volume movement cheaper.
This is the compliance challenge Teng is trying to contain. The issue is not only whether one named person was sanctioned on one date. It is whether an exchange can identify a payment network when the network uses ordinary market tools, third-party brokers, offshore entities and wallets that may look clean until outside intelligence links them together.
Business Keeps Moving While Trust Lags
There is a tension in the company’s public moment. Regulators are studying the old wounds while the business continues to seek licenses, list products, delist tokens and compete for users. That split is visible in recent Thunder Tiger Europe coverage of Binance’s ADGM license in Abu Dhabi, a reminder that the exchange’s growth story has not paused while Washington reopens the compliance file.
Operational controls also show up in smaller, user-facing ways. When a platform removes assets, tightens access or changes account rules, retail users feel compliance as product friction. The same site has covered Binance token delisting deadlines, the kind of routine exchange action that sits far from sanctions law but still shapes trust in platform governance.
That matters because the company has spent two years trying to tell a comeback story. New management, new controls, new law-enforcement cooperation, new market licenses. The WSJ dispute cuts into that story at the most sensitive point: whether the system changed enough after the guilty plea.
Sen. Richard Blumenthal, ranking member of the Senate Permanent Subcommittee on Investigations, had already sent Teng a February letter demanding records related to Iran-linked entities, Russian shadow-fleet activity, Tether, USD1 and the dismissal of compliance staff. The Senate request to Richard Teng shows why another Iran story is not landing on a blank page.
The Legal Risk Now Sits in the Gaps
The next phase will turn on documents, not adjectives. The company can argue that the Journal overstated platform exposure or mixed direct exchange flows with wider network activity. Lawmakers and regulators can argue that repeat warnings, account links and wallet exposure matter even when sanctions labels arrive later.
Four evidence trails now matter most:
- Account chronologies showing when users traded, when they were flagged and when they were sanctioned.
- Internal alert records showing whether compliance staff escalated the same accounts or counterparties more than once.
- Wallet attribution records separating direct platform deposits and withdrawals from broader network volume.
- Monitor findings showing whether post-settlement controls changed outcomes, not only policies.
None of those trails can be settled by a social media post. They sit in databases, audit logs, case files and regulator correspondence. That is why the company’s denial may be only the first move.
If the exchange can show clean timing, documented reviews and prompt escalation, the May 22 dispute becomes another contested media fight. If the records show repeated warnings around the same Iran-linked infrastructure, the proof gap shifts from one article to the company’s whole post-plea compliance promise.
