Tether disclosed it assisted in freezing approximately $550 million in USDT linked to Iran-connected wallets, one of the largest single sanctions-related stablecoin freezes on record. A Senate minority report released the same day found USDT was the dominant asset in 84% of 846 wallets tied to Iran and affiliated proxies, heightening congressional focus on stablecoin sanctions compliance.
For Armada's crypto-repo desk, the freeze event reinforces that USDT carries unilateral issuer freeze risk, a material factor if stablecoins are held as collateral margin or settlement float by counterparties. Armada's no-rehypothecation policy limits direct exposure, but counterparty liquidity could be impaired if their USDT balances are frozen mid-transaction. AML screening and counterparty due diligence procedures should explicitly account for sanctions-related USDT freeze scenarios.
