Tether CEO Paolo Ardoino has published a response to US Senator Blumenthal’s analysis of the stablecoin issuer’s sanctions compliance, stating that since 2023, Tether has frozen relevant addresses an average of four weeks ahead of official sanctions from OFAC and NBCTF. In 99% of related cases, these freezes also predate Chainalysis’ labeling of the addresses in question. Ardoino added that Tether’s actions have reduced Iran-related stablecoin trading volume by 94%, and its cooperation with law enforcement enables it to respond rapidly to emerging threats. The response follows Blumenthal’s release of a Democratic staff report from the Senate Permanent Subcommittee on Investigations on September 28. The report claimed that among 846 wallets analyzed that were sanctioned or designated as seizure targets for ties to Iran and its regional proxy groups, 84% used only or nearly only USDT for transactions. It accused Tether of failing to adequately freeze illegal wallets, prompting Blumenthal to call on the US Treasury Department and Department of Justice to investigate the firm’s anti-money laundering and sanctions compliance practices. In a separate statement issued the same day, Tether noted that since the start of 2026 alone, it has helped freeze approximately $550 million in Iran-related USDT, with the relevant wallets identified by US authorities as linked to the Central Bank of Iran and sanctions evasion networks.
