Two Thai businessmen have filed suit in Manhattan federal court alleging that Tether froze 42.4 million USDT across 10 Ethereum addresses in a single two-and-a-half-minute batch on October 30, 2025, nearly three months before a seizure warrant dated February 19, 2026. The lawsuit contends the freeze was executed in advance of and without a valid legal order at the time, raising due process questions about Tether's freeze mechanism and its coordination with law enforcement.
For Armada's crypto repo desk, this case is a concrete illustration of unilateral issuer intervention risk in stablecoin-adjacent collateral. Even if Armada does not accept USDT as direct collateral, counterparties using USDT for margin or settlement could face sudden asset immobilization. Armada's no-rehypothecation policy and Fireblocks SOC 2 custody posture do not insulate against issuer-level freeze risk, making explicit collateral policy documentation and counterparty disclosure essential.
