Blumenthal claims Tether fuels Iranian sanctions evasion
- Senator Blumenthal accused Tether of laundering $603 million for Iranian military and proxy networks.
- Tether countered that public blockchains allowed the company to freeze $550 million in illicit funds in 2026.
- Analyst David Bennett claims Washington is squeezing Tether to protect domestic stablecoin rival Circle.
Washington wants Tether off the board.
Senator Richard Blumenthal released a staff report accusing Tether's USDT stablecoin of serving as the primary financial engine for Iranian sanctions evasion. According to the Senate subcommittee investigation, 84 percent of 846 crypto wallets flagged by American and Israeli authorities transacted predominantly in USDT. Between 2021 and 2025, investigators tracked more than $603 million flowing through networks tied to Hezbollah, the Houthis, and Iranian military procurement channels.
Tether chief executive Paolo Ardoino pushed back immediately, arguing that public blockchain ledgers grant law enforcement far greater visibility than legacy cash networks. The company pointed to $550 million in Iran-linked digital assets it froze in 2026 alone as proof of active cooperation. Blumenthal, however, framed USDT as an unchecked superhighway for money laundering, calling on federal authorities to launch formal compliance investigations into the offshore issuer.
The Senate report also turned up heat on Wall Street links, explicitly highlighting Cantor Fitzgerald’s role as Tether's reserve custodian. Blumenthal singled out former chief executive Howard Lutnick’s recent decision to transfer his equity stake to his children, framing the relationship as a critical point of exposure for the domestic banking system.
On Bitcoin & Economic News, analyst David Bennett argued that the sudden congressional pressure is less about national security and more about commercial protectionism. Bennett claimed that lawmakers are leveraging regulatory enforcement to hobble Tether's global dominance and carve out market share for U.S.-regulated competitors like Circle. While statutory banks face heavy compliance burdens, the timing of Blumenthal's offensive suggests a targeted attempt to rein in offshore stablecoin rails.
The assault on Tether marks a widening front in Washington's effort to enforce global financial compliance through stablecoin bottlenecks. By targeting the world's largest digital dollar issuer, lawmakers are attempting to force a choice between strict U.S. banking integration and total isolation from Western financial markets.
The battle over dollar liquidity is no longer monetary policy - it is geopolitics.
