Binance's 97.3% Iran cleanup figure starts from a $4.19 million base
Manhattan prosecutors are examining whether Binance knowingly allowed trading that breached US sanctions on Iran, and the compliance numbers the exchange offers in response cover four named venues and about $4 million of flow.
The Investor · Invest desk

What happened
- Binance is not a party to that forfeiture case, and chief executive Richard Teng has said the complaint does not allege wrongdoing by the exchange.
- Binance says its direct exposure to four major Iranian exchanges fell 97.3% over two years, from $4.19 million to $110,000, and that users located in Iran are barred.
- Binance and then-chief executive Changpeng Zhao pleaded guilty in 2023, with more than $4.3 billion in penalties and a three-year independent compliance monitor attached.
Why it matters
- Who's exposed exposure TRM Labs puts foreign institutions that need US market access inside the secondary sanctions perimeter, so the cost of routing size through a venue under active review is borne by the institution's own banking relationships, not by the venue.
- What it limits constraint Reallocating away from a venue holding 38.7% of top-ten share means splitting flow across nine books averaging about 6.8% each. That prices as worse execution.
- Who has to decide decision Any desk that wants comfort has to decide whether a metric covering about 0.45% of the flow the Justice Department described in 2023 answers the question its compliance committee is actually asking.
- What doesn't add up contradiction Cryptopolitan credits Reuters for the same division of prosecutorial labour that Cointelegraph credits to Bloomberg, so a reader tracking how many outlets have independently confirmed the probe should count carefully.

Binance's answer to the sanctions question is a ratio built on a small base. The exchange says its direct exposure to four major Iranian exchanges fell 97.3% over two years, from $4.19 million to $110,000 [21]. That is a decline of about $4.08 million [25]. In the 2023 settlement, the Justice Department said Binance had facilitated more than $898 million in trades between US users and Iran-based users from 2018 to 2022 [20]. So the flow the exchange has cut is roughly half a percent of the conduct prosecutors described [26]. Binance supplied the figures [22].
Prosecutors in the Southern District of New York say Blessed Trust and Hexa Whale used Binance accounts to move money to the Iranian government and the Islamic Revolutionary Guard Corps [11]. They say self-custodied wallets grouped as "Entity A" received and distributed more than $1.5 billion in illicit oil proceeds [18]. The forfeiture case that preceded the probe does not describe exchange-to-exchange traffic. The roughly $61 million the complaint seeks is about 4% of that network [28]. Binance is not a party [12], and chief executive Richard Teng said the complaint "was not filed against @binance and does not allege any wrongdoing by Binance" [13]. Binance says both accounts were removed after internal investigations [16].
For an institution, the constraint is depth. Cryptopolitan, which does not date the reading [24], cites CoinGecko putting Binance at 38.7% of the market share of the top ten centralized exchanges [23]. That leaves 61.3% split across the other nine, an average of about 6.8% each [29]. TRM Labs says the Treasury action of August 24 brought five sectoral determinations under Executive Order 13902, covering digital assets, technology, gold, aviation and shipping [14]. It says that action raises secondary sanctions risk for institutions processing large transactions for Iranian exchanges or digital-asset firms, including foreign institutions that need access to US financial markets [19].
Cointelegraph attributes the new detail to Bloomberg, which reported Tuesday that the Manhattan US Attorney's Office is examining whether Binance knowingly allowed trading that violated Iran sanctions [1]. The same report has the Justice Department's Criminal Division in Washington also involved [2]. Cryptopolitan attributes the same division of labour to Reuters [3]. The underlying probe was first reported in March by the Wall Street Journal, which said it was unclear whether the DOJ was investigating Binance, its users, or both [7]. Binance told Cointelegraph then that it was not aware of any DOJ investigation [8]. This week a Binance spokesperson told Cointelegraph: "We maintain a zero-tolerance policy for sanctions violations. We fully cooperate with law enforcement, and we remain committed to rooting out and shutting down bad actors" [4]. The Justice Department declined to comment [9].
The 2023 plea also came with more than $4.3 billion in penalties and a three-year independent compliance monitor [15], a term that on those dates lapses in 2026 [27]. Cointelegraph reports a US senator has asked for an update on that monitor [17].
I'd expect the monitor decision to move institutional behaviour before any charge does, because a compliance officer can act on a lapsed or extended monitorship and cannot act on an open inquiry. The counter-case is straightforward: Cointelegraph notes an investigation does not establish wrongdoing and may conclude without charges [6], in which case 38.7% share goes unbothered and this is legal expense. Evidence against my view would be venue distribution holding flat through a monitor extension.
What to watch
- Whether the three-year compliance monitor from the 2023 plea is extended or lapses in 2026, and what the senator's requested update says.
- Whether the Southern District of New York amends the $61 million forfeiture complaint to name Binance, or brings charges against the exchange.
- Whether CoinGecko's top-ten share reading for Binance moves off 38.7% in the months after the probe was reported.
