The stablecoin issuer Tether is facing legal and regulatory scrutiny regarding its financial operations and ties to major financial institutions.

In a lawsuit filed in the U.S. District Court for the Southern District of New York, Conduit Technology alleged that Tether unilaterally froze $2.76 million in USDT from its corporate treasury wallet. Conduit claims the freeze, which occurred in September 2025, was linked to a Brazilian police investigation into other entities but lacked legal justification. The company stated the freeze caused significant business disruption and is seeking the restoration of funds and damages.

Simultaneously, Senator Richard Blumenthal has launched a formal inquiry into Cantor Fitzgerald due to its reported $10 billion stake in Tether and its role in managing the custody of U.S. Treasury securities backing USDT. The Senate investigation is examining whether Tether’s assets are being used to circumvent international sanctions and is requesting transparency regarding communications involving Commerce Secretary Howard Lutnick.
