Senate Inquiry Identifies USDT as Key Channel in Iran Shadow Banking

A U.S. Senate investigation identified stablecoins, especially Tether’s USDT, as a key liquidity channel supporting Iran’s shadow banking system, increasing sanctions-compliance pressure on virtual-asset service providers in Gulf markets.

Licensed virtual-asset service providers in Gulf jurisdictions face greater scrutiny as they assess wallet ownership, counterparties and transaction exposure involving Iran-linked activity. They are expected to strengthen controls for incoming and outgoing funds.

Stablecoin branding or the currency used for settlement does not determine legal ownership or sanctions exposure. Indirect or historical wallet links alone do not automatically establish a violation; the relevant rules, transaction participants and specific facts must be assessed together.

In the United Arab Emirates and other regulated markets, licensed exchange wallets remain subject to monitoring, and funds may be frozen before consumer settlement. Merchants must complete know-your-customer checks, while regulated service providers handling deposits and withdrawals carry responsibility for counterparty and sanctions-risk assessments and related controls.

The findings add to U.S. scrutiny of how dollar-pegged stablecoins are used in sanctions-sensitive financial networks.
