Key Takeaways
Tether disclosed on September 28, 2026 that it helped freeze nearly $550 million in Iran-linked USDT this year, working with US authorities including the Treasury's OFAC.
The actions included a $344 million freeze in April across two addresses and a $130 million freeze in July across four TRON wallets, often before formal sanctions designations.
Tether says it has now frozen more than $4.9 billion in assets globally through cooperation with over 340 agencies in 67 countries.
Tether disclosed on September 28 that it helped freeze close to $550 million in Iran-linked USDT during 2026, acting alongside US authorities including the Treasury Department's Office of Foreign Assets Control. The stablecoin issuer published the figures on its own site, and they were reported by crypto.news.
The largest single action came in April, when Tether froze $344 million across two addresses. A July action froze another $130 million across four wallets on the TRON network. In several cases Tether says it acted on information from OFAC before formal sanctions designations were issued, freezing funds ahead of the public paperwork.
The company put the year's Iran-linked total near $550 million and said it has frozen more than $4.9 billion in assets worldwide over its history, through cooperation with what it described as more than 340 agencies across 67 countries, including US law enforcement and Israel's counter-terror financing bureau.
Chief executive Paolo Ardoino argued that a public blockchain makes the money easier, not harder, to track.
USDT is "not a haven for sanctioned actors, terrorist organizations or criminal networks."
The timing is the sharp part. In several freezes Tether moved before the sanctions list caught up, something only a centrally issued token can do, and that power cuts both ways. The same switch that stops sanctioned money is the one critics fear can reach ordinary users, a tension the industry keeps running into as a $387.5 million exchange breach showed how hard stolen crypto is to claw back and as prosecutors chase crypto laundering networks across borders. For now, the freeze is a feature regulators want. Worth watching how far it goes.
