US sanctions A7 Network over $179 billion ruble stablecoin flows

The US Treasury sanctioned the A7 Network on October 1, naming the Russia-based money operation a criminal organization and blocking its ruble-backed A7A5 token. Treasury said the network moved billions for Russia and Iran to dodge sanctions.

Officials at the Office of Foreign Assets Control, the Treasury arm that enforces US sanctions, announced the designation as part of a campaign they call Operation Economic Outcast. The Financial Crimes Enforcement Network, FinCEN, moved alongside it.

What Treasury says the A7 Network did

A7 is a cross-border payments operation tied to Russia. Treasury describes it as a web of front companies and middlemen it calls sub-agents. Those sub-agents processed more than $17 billion in transfers between January 2025 and June 2026, the department said.

Treasury said A7 claimed about 7.5 trillion rubles in volume as of January 2026, worth roughly $91.5 billion at the time. The network grew out of earlier Russian payment channels and ran through sub-agents in several countries. Each sub-agent worked as a relay. Money could change hands many times before it reached its destination.

Its named leader is Ilan Shor, a businessman the US and its allies had already sanctioned and whom Treasury calls a convicted fraudster. Treasury first hit parts of the structure, including the firm A7 LLC, in August 2025. This action widens that net.

A7A5 and the $179 billion question

A7A5 is a token pegged to the Russian ruble. Old Vector LLC issued it. Treasury had already sanctioned Old Vector in August 2025, and it now lists the token itself as blocked property, which bars US people and firms from holding or trading it.

FinCEN said it found more than 180 entities that moved at least $179.1 billion worth of A7A5 between February 2025 and June 2026. That number leads much of the coverage. That is easy to misread. The $179.1 billion is the token's total throughput, not a count of confirmed illicit value. The narrower figure Treasury ties to sanctions evasion is the $17 billion its sub-agents handled.

To put that in scale, $179 billion is bigger than the yearly economic output of many mid-sized countries. Most of that flow was ordinary token movement, not proven crime. Treasury has not said how much of it broke the law. Regulators around the world are still writing the rules for stablecoin issuers, and A7A5 shows how a token can be built to break them.

The Iran link and a proposed ban

Iran is why Treasury framed the case as a national security matter. The department said the network carried funds for the Central Bank of Iran, the Islamic Revolutionary Guard Corps and Iran-linked groups. It also tied A7 to Nobitex, Iran's largest crypto exchange, which the US sanctioned in June 2026. One sub-agent took in about $140 million from entities tied to Iranian sanctions evasion, Treasury said. Another sent $1.6 million to a company linked to weapons buying.

Treasury Secretary Scott Bessent said the goal is to dismantle "the financial infrastructure that allows Iran and other adversaries to evade sanctions." FinCEN went further than the sanctions list. It proposed a rule that would stop US banks and crypto firms from handling any transfer that touches an A7 sub-agent, in dollars or in crypto. The proposal opens a 30-day public comment window once it appears in the Federal Register. FinCEN also issued an alert listing warning signs that banks can use to spot A7 activity.

It is one of several crypto-focused sanctions moves from Treasury in recent days, after a separate case against a Hamas-linked fundraising network. Both cases point to the same tactic: cut the money rails rather than chase each wallet.

What to watch

The sanctions take effect now. Their real bite depends on enforcement. Old Vector and the A7 Network sit mostly outside US reach, in Russia and friendly states, so freezing US-based assets may catch little. The pressure instead falls on exchanges, banks and stablecoin firms that could touch A7A5 or its sub-agents and risk secondary sanctions of their own.

Watch whether big exchanges blacklist A7A5 addresses, and whether FinCEN's proposed rule clears its comment period intact. Neither Shor nor anyone behind the A7 Network has publicly responded to the designation.
