US Prosecutors Target $61 Million in Tether Tied to Iran Oil Sales

Federal prosecutors in Manhattan have filed a civil forfeiture complaint seeking to seize roughly 61.2 million USDT spread across 10 Tron blockchain addresses, alleging the funds trace back to black-market sales of Iranian oil and petroleum products that benefited the government of Iran and the Islamic Revolutionary Guard Corps. The filing, lodged by the US Attorney’s Office for the Southern District of New York, is notable not just for its size but for what it reveals about the scale of the network allegedly moving oil money through crypto exchanges and US correspondent banking channels.

The complaint describes a far larger web of activity than the targeted 61 million tokens suggest. Prosecutors say a cluster of at least seven addresses, referred to in the filing as “Entity A,” moved roughly $1.5 billion in total. Two companies named in the case, Blessed Trust Limited and Hexa Whale Trading Limited, allegedly received massive wire transfers through US correspondent accounts: $443.49 million to Blessed Trust between November 2024 and March 2025, and $37.15 million to Hexa Whale between March and April 2024. The alleged activity spans Iran, Hong Kong and Middle Eastern jurisdictions, illustrating how sanctioned oil proceeds can be laundered through a chain of intermediaries before touching the US financial system.

How the seizure actually works

Unlike a traditional asset seizure, US authorities do not need to obtain private keys to take control of the funds. Tether, the issuer of USDT, froze seven of the ten named addresses in June 2025 and the remaining three in July 2025, effectively locking the tokens in place months before the forfeiture complaint was filed. A seizure warrant now allows federal agents to move the frozen funds into FBI custody. Mechanically, Tether will burn the frozen tokens and mint an equivalent amount of new USDT directly into a wallet controlled by the FBI — a process that has become the standard playbook for US authorities working with stablecoin issuers.

This mechanism is central to why the case matters beyond its dollar figure. It demonstrates that a centralized stablecoin issuer functions as a chokepoint that law enforcement can lean on, something that has no clean equivalent in cash-based sanctions evasion. Tether says it has now worked with more than 340 law enforcement agencies across 67 countries and has helped freeze over $5 billion in suspected illicit funds globally. The company’s cooperation also factored into a separate, unrelated case: a $52 million sum credited to Tether’s assistance in the Xinbi Guarantee money-laundering investigation, which the DOJ has pursued independently of the Iran oil matter.

Binance is named among the entities in the case, though the exchange has not been accused of wrongdoing. Binance CEO Richard Teng said the company has cooperated with law enforcement throughout and pointed to a “zero tolerance” policy on sanctions violations. Nobitex, an Iran-linked exchange, also appears in the facts of the case, underscoring how transactions allegedly flowed through multiple platforms before reaching US-connected banking rails.

What it means for stablecoins and enforcement

For everyday users, the case is a reminder that stablecoins like USDT are not bearer instruments in the way people sometimes assume. Tether can and does freeze addresses at the request of law enforcement, and it has built the operational relationships to do so at scale. That capability cuts both ways: it gives authorities a powerful tool against sanctions evasion, but it also means that USDT holdings are subject to intervention in ways that cash or even self-custodied bitcoin are not.

The case also lands amid a broader tightening of the regulatory environment around crypto’s financial plumbing. Central banks have begun flagging the systemic weight of stablecoins directly — the Bank of England recently warned that stablecoins now move Treasury markets, a sign that what was once a niche instrument for traders has become material to sovereign debt liquidity. At the same time, US lawmakers have struggled to build a comprehensive rulebook for the industry; the Senate’s recent failure to advance the Clarity Act left much of crypto’s federal framework unresolved, a gap documented in our report on the Senate blocking the Clarity Act. Enforcement actions like this forfeiture complaint are, in effect, filling part of that vacuum through case-by-case prosecutions rather than statute.

What comes next

Several threads from this case are worth watching. The civil forfeiture process itself will play out in the Southern District of New York, where courts will need to weigh the government’s evidentiary claims about the oil-proceeds origin of the funds. Whether additional companies or individuals tied to the $1.5 billion Entity A cluster face separate charges remains an open question, given that the current complaint targets only a fraction of that total. It is also worth watching whether Binance’s cooperation posture, as described by Teng, extends into any formal findings once the case develops further.

More broadly, this forfeiture sits alongside a string of recent stories about how crypto infrastructure intersects with security and compliance failures elsewhere in the industry, from the fake government domain that tricked Revolut into leaking customer data to new EU rules requiring wallet makers to report breaches within 24 hours. Together, these cases point to a maturing but still uneven enforcement landscape, where stablecoin issuers, exchanges and banks are being pulled increasingly into the role of financial gatekeepers.
