The US Treasury Department has imposed sanctions on the A7 Network, which US authorities described as a shadow financial system tied to Russia and used to support sanctions evasion and other illicit transfers. Treasury also said the network was used in activity involving Iran, including movement of funds connected to Iranian state-linked actors.
In actions announced on October 1, the Office of Foreign Assets Control designated the A7 Network as a significant transnational criminal organization, while the Financial Crimes Enforcement Network proposed new restrictions on fund transfers involving the network’s sub-agents.
Treasury action targets cross-border network
According to the Treasury, the A7 Network relied on companies in third countries and international payment channels to bypass sanctions. The department framed the network as an alternative financial structure operating outside standard compliance controls.
The measures combine sanctions with a proposed regulatory step. OFAC’s designation places the network under sanctions, and FinCEN’s proposal would restrict certain transfers involving its sub-agents if adopted. Treasury also issued a risk alert intended to help financial institutions spot potentially suspicious activity linked to the network.
FinCEN says sub-agents handled over $17 billion
US authorities said the network operated at significant scale. A FinCEN investigation found that A7 Network sub-agents processed more than $17 billion globally between January 2025 and June 2026.
That figure was presented as part of the government’s case for tighter controls. The Treasury did not describe the entire sum as a single category of conduct, but cited the volume to underscore the reach of the network’s global payment activity.
US links the network to Iran-related transfers
Treasury said the A7 Network was used to move funds for the Central Bank of Iran, Iran’s Islamic Revolutionary Guard Corps, or IRGC, and other Iran-linked groups. US authorities said some subgroups were also involved in transactions tied to sales of Iranian oil and to weapons procurement.
Those claims place the network at the intersection of US sanctions policy on both Russia and Iran. The government’s announcement characterized the system as a vehicle for sanctions evasion as well as broader illicit finance.
Authorities also point to crypto infrastructure
The Treasury said cryptocurrency tools were part of the network’s cross-border infrastructure. In particular, it identified A7A5, a ruble-pegged token issued by Old Vector, as an element authorities believe was used for international fund transfers and sanctions evasion.
The reference to A7A5 suggests the US action is not limited to conventional payment routes. Treasury’s description indicates that digital asset infrastructure was, in its view, integrated with the network’s wider methods for moving money across borders.
Next step is closer scrutiny by financial firms
Beyond the sanctions announcement, the most immediate confirmed follow-up is the risk alert issued to financial institutions. Treasury said the notice is meant to help banks and other firms identify transaction patterns that may be connected to the A7 Network.
FinCEN’s proposed rule is also a key next step. If advanced, it would add restrictions on transfers involving the network’s sub-agents, extending the US response beyond designation and into ongoing transaction controls.
