The U.S. Treasury Department has expanded sanctions pressure on Iran and the Russia-linked A7 Network. In a separate action on Oct. 1, 2026, the Office of Foreign Assets Control designated A7 as a significant transnational criminal organization under Operation Economic Outcast, alleging that the network helped Iran, the Islamic Revolutionary Guard Corps and affiliated proxy groups evade sanctions. FinCEN proposed barring U.S. financial institutions from processing transactions tied to A7 sub-agents and issued an alert on related financial-crime red flags. Treasury also identified A7A5, a ruble-backed stablecoin, as blocked property. A7 reportedly handled more than 2,000 transactions a day as of January 2026, with activity exceeding 7.5 trillion rubles, or about $91.5 billion, while its sub-agents processed more than $17 billion globally between January 2025 and June 2026. The measures build on the Aug. 14, 2025, designation of A7 LLC and Old Vector LLC and broaden the focus to the wider network and its intermediaries. Treasury’s broader sanctions package also targeted Iran’s two largest automakers, Iran Khodro and SAIPA, railway companies and the country’s automotive and rail sectors.
