A Senate Report Says 84% of Iran-Linked Crypto Wallets Used Tether. Is USDT Safe to Hold? - 24/7 Wall St.

A U.S. Senate report has found that 84% of crypto wallets linked to Iran relied on Tether (USDT), according to 24/7 Wall St. The finding puts a spotlight on how the world's largest stablecoin by market capitalization is used — and on the compliance controls that surround it.

For context, the report describes a pattern of usage rather than alleging any failure by Tether itself. The distinction matters. Stablecoin issuers are expected to screen wallet addresses against sanctions lists and to freeze funds when required, and Tether has previously announced such freezes. The key question for observers is not whether USDT appears in illicit activity — dollar bills do too — but whether the issuer detects and blocks it quickly enough to satisfy regulators.

What to watch: any formal regulatory response to the report, Tether's own disclosures about frozen or blacklisted addresses, and whether exchanges tighten monitoring of USDT flows tied to high-risk jurisdictions. These are the signals that will shape how the market judges the compliance risk attached to the token.
