US Sanctions A7 Network After $17B in USDT Conversions

On Oct. 1, 2026, the U.S. Treasury designated the Russia-linked A7 Network as a significant transnational criminal organization and extended blocking sanctions to the broader payment network. The Financial Crimes Enforcement Network proposed a rule to bar covered financial institutions from transmitting funds involving A7 sub-agents after reporting the network processed more than $17 billion in dollar-denominated transactions between January 2025 and June 2026.

The Treasury designation requires firms subject to U.S. jurisdiction to freeze and report property and interests in property belonging to blocked persons to the Office of Foreign Assets Control, including entities 50% or more owned by sanctioned parties. Blocking sanctions take effect immediately where U.S. jurisdiction applies.

FinCEN’s proposal would prohibit covered banks, crypto exchanges and other financial firms from sending or receiving funds involving identified A7 sub-agents. The rule targets intermediaries and liquidity providers that A7 used to convert its internal A7A5 token into liquid assets such as Tether’s USDT, which can be exchanged for fiat currency for cross-border payments.

FinCEN reported that A7A5 functioned as an internal accounting and settlement asset backed by ruble deposits at Promsvyazbank. The agency found the network repeatedly converted A7A5 into USDT and other widely used digital assets to access global liquidity.

FinCEN reported that A7 relied on a network of sub-agents and foreign intermediaries that masked the network’s role through trade documents and payment instructions designed to resemble ordinary commercial payments. Exchanges, over-the-counter brokers and other liquidity providers outside Russia will face increased screening obligations to identify counterparties, wallet addresses or payment routes tied to A7 property.

Under the proposed rule, institutions receiving crypto from listed sub-agents would be expected either to block the assets where other sanctions rules require that outcome or to reject the transfers and deny recipients access. FinCEN plans to provide the identities of covered sub-agents through its secure FI-Portal and would require firms to apply risk-based procedures to detect prohibited transactions. The proposal will be open for public comment for 30 days after publication in the Federal Register.

U.S. officials identified A7 services as having been used to move money for some Russian sanctioned entities, Iran’s central bank and the Islamic Revolutionary Guard Corps. The measures focus on the conversion route that turns ruble-backed tokens into dollars and dollar-linked stablecoins.
