Tether CEO disputes Senate Iran sanctions report, claims proactive freezes cut volumes 94%

Tether CEO Paolo Ardoino disputes a Senate report accusing the company of slow sanctions enforcement, claiming proactive wallet freezes reduced Iran-linked USDT volumes by 94% since 2023.

Why it matters

The dispute highlights ongoing regulatory scrutiny of stablecoin issuers' sanctions compliance and could influence future enforcement actions or legislation targeting crypto's role in illicit finance. The conflicting claims about freeze timing remain unresolved.

What happened

Tether CEO Paolo Ardoino pushed back against a September 28 report from the Senate Permanent Subcommittee on Investigations led by Senator Richard Blumenthal, which accused USDT of providing a financial lifeline to Iran's shadow banking network. Ardoino claims Tether froze suspicious addresses an average of four weeks before official OFAC and Israeli designations since 2023, and before Chainalysis labels in 99% of cases, driving a 94% decline in Iran-linked stablecoin volumes. The Senate report analyzed 846 sanctioned wallets and found 84% transacted exclusively or nearly exclusively in USDT. TRM Labs data cited by CoinGape shows USDT's share of Iran-attributed wallet volume fell from 67% in 2025 to 14% by August 2026. Blumenthal has requested federal investigations into Tether's sanctions and anti-money-laundering practices. The two sides disagree on whether Tether acts ahead of or behind official sanctions designations.
