Fact Check
Multiple independent sources confirm each element of the claim. The PANews article 'Tether在TRON网络冻结共持有1.31亿枚USDT的四个钱包' confirms Tether froze four TRON wallets holding 131 million USDT. The Specter (@SpecterAnalyst) tweet confirms the wallets are linked to OFAC-sanctioned IRGC and the Central Bank of Iran. The second PANews article and the tradersunion.com report both confirm Treasury Secretary Scott Bessent tied the action to freezing over $130 million in Iran-linked digital assets over illicit finance/sanctions evasion. The '131 million USDT'/'over $130 million' figures are consistent across sources. The primary caveat is that the freeze figures and the 'illicit finance' framing rely on the same closely-linked reporting cluster, but the corroboration across Tether reporting, the on-chain analyst, and Treasury statements is strong.
Summary

The U.S. Treasury identified four additional Tron wallets tied to the Central Bank of Iran, and Tether blocked about $131 million in USDT after the addresses received more than $165 million in stablecoins, according to Chainalysis. The move expanded an existing designation rather than imposing new sanctions on the bank, which has been blocked under U.S. counterterrorism authority since 2019 over support for the IRGC-Qods Force and Hezbollah. Treasury Secretary Scott Bessent said the U.S. would keep pursuing illicit revenue channels used by Iran, while OFAC said published wallet lists are not exhaustive. The action followed June sanctions on Nobitex and other Iranian exchanges and built on an April Tether freeze of $344 million linked to the bank, bringing the total blocked across the two actions to roughly $475 million. The newer report said the sanctions step also weighed on crypto sentiment alongside a widening US-Iran military conflict, with Bitcoin falling to roughly $62,870-$63,800 after a reported US strike on Iranshahr Airport in southeastern Iran.
