US Treasury Sanctions Russia-Linked A7 Network, Says It Processed More Than $17 Billion

The US Treasury Department has sanctioned the A7 Network, a shadow financial system linked to Russia. US authorities said the network was also used to help Iran evade sanctions and move illicit funds.

On October 1, the Treasury said the Office of Foreign Assets Control designated the A7 Network as a significant transnational criminal organization. The Financial Crimes Enforcement Network also proposed a rule to restrict fund transfers involving the network’s sub-agents.

The Treasury said the A7 Network used companies in third countries and international payment networks to circumvent sanctions. A FinCEN investigation found that the network’s sub-agents processed more than $17 billion globally from January 2025 through June 2026.

The Treasury said the network was also used to move funds for the Central Bank of Iran, Iran’s Islamic Revolutionary Guard Corps, or IRGC, and Iran-linked groups. Some subgroups were also involved in transactions tied to sales of Iranian oil and weapons procurement.

Cryptocurrency infrastructure was also used. The A7 Network includes A7A5, a ruble-pegged token issued by Old Vector, which US authorities believe was used for cross-border fund transfers and sanctions evasion.

Alongside the action, the Treasury issued a risk alert for financial institutions to help identify suspicious transactions linked to the A7 Network.
