Blumenthal's report hands Treasury a Tether case four months before it can bar noncompliant tokens
Sen. Richard Blumenthal's report says Tether left 34 of 39 Hezbollah-flagged wallets open for nine months as $34.6 million moved through. It reaches Treasury about four months before the secretary can bar US platforms from trading a noncompliant issuer's token.

What happened
- Israel's counter-terror financing bureau flagged the 39 addresses in June 2023 as tied to a Hezbollah money launderer, and Tether froze five of them at the time.
- Blumenthal has asked the Treasury and Justice departments to investigate Tether's sanctions and anti-money-laundering compliance.
- Of 846 wallets sanctioned or targeted by Israel or OFAC between June 2021 and August 2026, 84% dealt exclusively or nearly exclusively in USDT, the subcommittee found.

Why it matters
- decision After January, whether US platforms may keep trading USDT becomes the Treasury secretary's call, and a preliminary but documented case is already on file.
- cost Meeting the report's standard would shift the first screening judgement, and its expense, from governments to Tether, covering partners' clients before any designation exists.
- exposure Banks that custody Tether tokens take on a heavier compliance load if lawmakers apply bank-grade expectations to the token they hold.
Thirty-four open wallets out of 39 is 87% of the flagged set, and $34.6 million over nine months comes to roughly $3.8 million a month, or about $1 million per wallet [1][2][3]. The flag came from a state agency, so those nine months are the gap between a government designation and a freeze [1][2]. Paolo Ardoino, Tether's chief executive, set out when the company moves. Public blockchains give authorities visibility that cash does not, he said, "and Tether can act when credible information is provided by law enforcement" [13]. The report puts it this way: "Solely relying on the reactive freezing of wallets after designations will not work" [14].
The two sides count different things. Tether's April and July freezes add up to about $474 million, some 86% of the $550 million it cites for 2026, and the April tranche followed information from OFAC and US law enforcement [5][11]. Against that total the Hezbollah-linked flow is about 6% [6]. Ardoino said "Tether has consistently demonstrated that USDT is not a haven for sanctioned actors, terrorist organizations or criminal networks" [12]. His statement does not address the wallets the subcommittee says are still unfrozen, and Tether did not immediately respond to a request for comment on them [15].
Blumenthal wants issuers held to the bank standard of active monitoring and a duty to stop suspected laundering [16]. The report says issuers "should proactively monitor their partners and their partners' clients for high-risk activities" [17]. Omid Malekan of Columbia Business School said any argument for bank-grade screening "must grapple with the sad reality that bank-grade censorship often fails at stopping exact illicit flows like this" [18].
The evidence has limits. The report, "Tethered to Terrorism: Crypto & Iran's Shadow Banking Network," calls its findings preliminary, no Republican signed it, and the subcommittee has not published the underlying addresses, so no one outside it can reproduce the results [3][7]. Blumenthal's letters also asked both departments whether they had narrowed, paused or closed an inquiry into Tether. They cite news reports placing a Justice Department investigation around October 2024, and neither department has confirmed one [5].
The January law matters more than the letters. It bars a company from offering a stablecoin from a foreign issuer unless that issuer can and will obey lawful orders to freeze it [8]. Tether, based in El Salvador, is a foreign issuer [9]. The law also lets the Treasury secretary declare an issuer noncompliant and bar American platforms from trading its token [10]. I think the test, as written, is obedience to orders, and Tether's April freeze on OFAC information is the kind of record that meets it [8][11]. The 39 addresses came from an Israeli designation [1]. The counter-thesis is that the noncompliance power can rest on a pattern of slow response to public designations, and this report gives the secretary a documented one [10][14].
If Treasury uses that power after January, US platforms stop trading USDT [10]. If the departments say an inquiry was already closed, the report stays a political document [5]. Tether could also keep access by paying for the partner screening the report asks for [17]. This view is wrong if Treasury cites these findings in a noncompliance declaration.
Tether's US business already runs through a bank. Anchorage Digital Bank, N.A., a nationally chartered bank, issues its domestic token, USAT [19]. In the subcommittee's sample, 84% of 846 wallets comes to about 711 that dealt mostly in USDT [4].
What to watch
- Treasury's and Justice's replies on whether an inquiry into Tether was narrowed, paused or closed.
- Whether the Treasury secretary uses the noncompliance power against Tether once the January freeze rule takes effect.
- Whether the subcommittee publishes the flagged addresses or wins a Republican signature, letting outsiders test the 84% figure.
