Ex-Binance Investigator Claims Review of 2,000 Iran Accounts Was Shelved

A former senior financial crimes investigator at Binance told Internal Revenue Service agents in May that executives sidelined a proposed review of roughly 2,000 accounts suspected of serving users in Iran, according to his account relayed through his lawyer. The accounts in question moved approximately $1.2 billion through the exchange — a sum larger than the annual budget of several small national financial intelligence units.

The proposed internal inquiry carried a codename: Operation Loclock. It never proceeded as designed, according to the former employee. His lawyer says he has been subpoenaed to testify before a federal grand jury in Washington, which signals that federal prosecutors are actively gathering sworn evidence rather than merely reviewing documents. A subpoena, it should be noted, is not a charge; grand juries hear testimony in secret and often decline to indict.

What does Binance deny?

Binance disputes the core allegation on three fronts. The company says it continued investigating the accounts, that it did not violate U.S. sanctions on Iran, and that it is cooperating with law enforcement. It also offers a competing explanation for the investigator's departure: the employees involved, Binance says, were fired for violating customer data privacy rules.

That termination rationale deserves scrutiny. Data privacy violations are a plausible ground for dismissal at any exchange, yet the claim conveniently coincides with an employee who has since spoken to IRS agents. Binance has not publicly detailed what data was mishandled, when, or by whom. Absent those specifics, the denial rests on assertions the company has chosen not to substantiate. In plain terms: Binance says the investigators broke the rules, but it has not shown its work.

Where does the $61 million forfeiture fit?

A related civil forfeiture case, filed September 14, adds a concrete enforcement track to the story. The Department of Justice sought approximately $61 million in cryptocurrency, alleging that two entities — Hexa Whale Trading Limited and Blessed Trust Limited — used Binance accounts to move proceeds from Iranian oil sales.

The mechanics matter here. Civil forfeiture allows the government to seize assets without filing criminal charges against any person, and the $61 million represents about 5 percent of the $1.2 billion the shelved review supposedly covered. The two figures describe different scopes, so readers should not treat one as a subset of the other. As of November 9, no criminal charges had been filed in the federal investigation — a fact that cuts both ways. It may mean prosecutors lack evidence, or simply that a grand jury process remains underway.

Why does the grand jury subpoena matter?

The subpoena converts an internal dispute into a potential criminal exposure question. If the former investigator testifies that executives knowingly blocked a sanctions-related review, prosecutors could weigh whether that conduct amounts to willful blindness toward U.S. sanctions law — a far more serious allegation than a compliance lapse. His testimony, however, remains untested. Binance's version — continued investigation, no sanctions violation — has not been contradicted in any public filing, only challenged.

The Iran angle carries specific regulatory weight. U.S. sanctions administered by the Office of Foreign Assets Control prohibit American companies, and foreign companies using U.S. jurisdiction or the dollar system, from serving Iranian residents. An exchange processing $1.2 billion in Iranian-linked transfers would face questions not just about screening failures but about whether compliance staff flagged them and were ignored.

What happens next?

The timeline now runs on two tracks. The civil forfeiture case over the $61 million will proceed through federal court regardless of any charging decision, and the Washington grand jury will continue hearing testimony behind closed doors. Whether Operation Loclock becomes evidence of a cover-up or a dispute over fired employees depends on what the grand jury does next — and that record, by design, stays sealed until prosecutors choose to act.
