Key points

  • Tether CEO Paolo Ardoino stated Tether froze suspect addresses four weeks before OFAC and NBCTF sanctions designations on average since 2023.
  • Ardoino claimed Tether's compliance actions reduced Iran-linked stablecoin transaction volume by 94%.
  • The pushback follows a Senate subcommittee report led by Sen. Richard Blumenthal accusing Tether of aiding Iran's shadow banking system.

Tether has pushed back against findings from Senate Democrats regarding illicit finance, stating that its proactive compliance measures reduced Iran-linked stablecoin volume by 94% 1. Tether CEO Paolo Ardoino stated on social media platform X on Oct. 19, 2026, that an inquiry by the Senate Permanent Subcommittee on Investigations overlooked the firm's ongoing sanctions enforcement work 1.

The Senate report, spearheaded by ranking Democrat Sen. Richard Blumenthal, alleged that Tether provided a critical financial conduit for Iran's shadow banking infrastructure 1. Democratic investigators focused heavily on pre-2024 activity, alleging that Tether failed to comprehensively freeze flagged wallets and that groups including Hamas shifted toward promoting $USDT over other assets 1. Blumenthal previously urged federal authorities to investigate these links, as detailed in coverage of how Senator Blumenthal Urges DOJ and Treasury to Probe Tether Over Iran Financing 1.

Proactive Enforcement Claims

Ardoino countered that Tether regularly acts before government agencies publish formal actions 1. Since 2023, Tether froze illicit wallets an average of four weeks prior to official designation by the U.S. Treasury Department's Office of Foreign Assets Control (OFAC) and Israel's National Bureau for Counter Terror Financing (NBCTF) 1. Ardoino added that Tether froze 99% of flagged addresses before blockchain analytics firm Chainalysis officially labeled them 1.

Speaking remotely at DC Fintech Week, Ardoino expressed frustration that the Senate findings reached the press prior to Tether's review, noting that bad actors pushed off USDT are migrating to alternative payment methods beyond U.S. or Tether oversight 1. Meanwhile, Blumenthal continues to scrutinize Tether's ties to Wall Street partner Cantor Fitzgerald, alongside its hiring of former White House crypto adviser Bo Hines to lead its domestic division 1. At the time of writing, USDT traded at $0.9988.
