The U.S. Treasury has taken two separate actions against the A7 Network, a Russia-linked shadow banking system that the department says Iran and other sanctioned actors have used to move money. The measures combine an immediate sanctions designation with a proposed restriction on certain fund transfers. Keeping those steps separate is essential to understanding what has changed and what remains open for public comment.
Two agencies, two legal tools
The Office of Foreign Assets Control designated the A7 Network as a significant transnational criminal organization on October 1. That action blocks property and interests in property of the network that are in the United States or controlled by U.S. persons. It also reaches entities owned 50% or more, directly or indirectly, by blocked persons.
The Financial Crimes Enforcement Network took a different route. FinCEN proposed a rule that would prohibit covered financial institutions from sending or receiving funds involving the network’s Sub-Agents. Because this is a proposed rule, the transfer restriction is not final. Treasury said the comment period will close 30 days after the proposal appears in the Federal Register. FinCEN also issued an alert with indicators intended to help financial institutions identify and report suspicious activity connected to the network.
How Treasury describes the network
Treasury says A7 uses companies in third-country jurisdictions to make sanctioned or illicit payments look like ordinary commercial activity. The department alleges that the network relies on false trade documents, inaccurate import-export records and misleading descriptions of goods. Its Sub-Agents form the layer that receives and remits payments.
FinCEN’s investigation found that these Sub-Agents processed more than $17 billion between January 2025 and June 2026, according to Treasury. The department also cited the network’s own claim that it handled more than 2,000 transactions a day and over 7.5 trillion rubles in volume as of January 2026. Those figures have different evidentiary weight: the $17 billion figure is attributed to FinCEN’s investigation, while the larger volume figure is the network’s own representation.
Where crypto enters the case
Treasury identifies A7A5 as a blocked, ruble-backed token issued by Old Vector LLC, an entity sanctioned in August 2025. The department says the A7 Network created the token so members could transact internationally while generating revenue for sanctioned infrastructure providers. It also links the wider network to Nobitex, an Iranian digital-asset exchange sanctioned in June 2026, and to transactions related to North Korean exchange hacks.
The action does not say that every transaction involving a ruble-backed token or every cross-border crypto payment is illicit. It targets a named network, its controlled entities and conduct Treasury describes as sanctions evasion and money laundering. That scope matters for compliance teams assessing counterparties: the relevant questions concern ownership, control, payment routing and links to designated parties, not the presence of a token alone.
What firms should distinguish now
OFAC’s designation has immediate blocking and reporting consequences within its jurisdiction. FinCEN’s proposed transfer prohibition follows a rulemaking process. Financial institutions therefore need to distinguish current sanctions duties from a restriction that is still under consideration, while using the new alert as a source of detection indicators. Treasury also warns that sanctions violations can draw civil or criminal penalties, with civil enforcement possible on a strict-liability basis.
