Tether claims $550 million in Iran freezes, but $35 million slipped past Senate
Tether says it helped freeze almost $550 million in Iran-linked USDT throughout 2026, whereas Democratic investigators on a Senate subcommittee allege that delays in blacklisting some recognized wallets let tens of hundreds of thousands of {dollars} hold shifting.
A preliminary report launched Sept. 28 by Democratic minority workers of the Senate Permanent Subcommittee on Investigations analyzed 846 crypto wallets that US or Israeli authorities had sanctioned or focused for seizure over their associations with Iran and regional teams. The report stated 84% transacted solely or almost solely in USDT.
Sen. Richard Blumenthal, the Connecticut Democrat and rating member of the subcommittee, referred the findings to the Treasury and Justice departments and requested them to analyze Tether’s anti-money laundering and sanctions compliance.
The referrals don’t set up that Tether violated federal legislation or that both division has opened a brand new case.
Tether printed its personal statement the identical day, saying actions involving USDT had resulted in roughly $550 million being frozen throughout wallets that US authorities recognized as related to Iran’s central financial institution and Iranian sanctions networks.
The cash that moved earlier than the freeze
The Senate report’s 84% determine describes a specific inhabitants.
Investigators assembled the pattern from wallets recognized by the Treasury Department’s Office of Foreign Assets Control and Israel’s National Bureau for Counter Terror Financing as related to Iran or regional teams. The dataset lined over 5 years of designations via August 2026.
For its evaluation, the Senate report outlined a pockets as transacting “predominantly” in a digital foreign money when that asset represented greater than 80% of the greenback worth of its mixture transactions.
The quantity doesn’t present what share of all USDT transactions is illicit, nor does it measure crypto’s share of Iran’s total sanctions-evasion exercise.
USDT is designed to trace the US greenback and might transfer throughout blockchain networks with no typical financial institution switch. However, Tether retains issuer-level controls that may blacklist addresses and stop USDT held at them from shifting.
That makes the timing of a freeze the principle concern for Democratic investigators.
The minority workers report examined 39 wallets recognized by Israel’s NBCTF in June 2023 as related to Tawfiq Muhammad Sa’id al-Law, whom the US Treasury later sanctioned for offering monetary companies to Hezbollah.
According to the report, 5 of the addresses had been blacklisted, whereas the remaining 34 weren’t frozen till March 2024. Senate investigators calculated that greater than $34.6 million in USDT moved out of these wallets after the Israeli seizure discover was printed and earlier than the remaining addresses had been frozen.
Those findings by the Democratic minority are usually not a court docket dedication that Tether violated US legislation. They additionally concern an precedent days than the enforcement actions Tether highlighted from 2026.
Tether factors to motion earlier than public designation
On April 23, Tether stated it supported US authorities in freezing greater than $344 million in USDT throughout two addresses after receiving data from OFAC and different US legislation enforcement companies.
The following day, OFAC updated the Central Bank of Iran’s existing sanctions entry so as to add those self same two blockchain addresses as digital-currency identifiers. The itemizing hyperlinks the central financial institution to the IRGC-Qods Force and Hizballah.
Tether additionally stated greater than $130 million in USDT throughout 4 wallets was frozen in July because the Treasury expanded the Central Bank of Iran’s listed blockchain addresses.
Those two disclosed actions account for a minimum of $474 million of the roughly $550 million Tether says was frozen throughout 2026. The firm didn’t present a wallet-by-wallet breakdown reconciling the disclosed examples with the total headline whole.
CEO Paolo Ardoino stated Tether acts when authorities present credible data and argued that public blockchains give investigators visibility into fund actions that money doesn’t.
Meanwhile, the Senate report stated Tether acknowledged receiving a June 4 request for data and paperwork from the subcommittee but had not responded as of the report’s publication.
Tether’s Sept. 28 public assertion didn’t straight deal with the report’s 846-wallet evaluation or the $34.6 million instance of funds investigators say moved earlier than addresses had been frozen.
A separate US forfeiture case is looking for roughly $61 million in cryptocurrency allegedly tied to black-market Iranian oil gross sales. Federal prosecutors stated the broader community moved greater than $1.5 billion in proceeds and alleged that some funds had been supposed to profit Iran’s authorities and army, together with the Islamic Revolutionary Guard Corps.
The Justice Department said the forfeiture motion focused cryptocurrency allegedly related to sanctions evasion and cash laundering tied to Iranian petroleum gross sales.
The two units of proof illustrate each side of issuer-controlled stablecoins: authorities can immobilize massive balances as soon as they establish addresses, whereas delays earlier than blacklisting can go away funds free to maneuver.
Whether the delays recognized by Senate minority workers signify remoted enforcement gaps or broader compliance failures is now the query Blumenthal has requested federal companies to analyze.
