The U.S. Treasury on Oct. 1 designated the Russia-linked A7 Network as a significant transnational criminal organization, accusing it of helping Iran evade sanctions. The designation freezes A7-related property under U.S. jurisdiction and, in a parallel move, FinCEN proposed barring U.S. financial institutions from processing transfers involving A7's sub-agents — intermediaries the agency says processed more than $17 billion in dollar-denominated transactions between January 2025 and June 2026.

The action extends an August 2025 sanctions package against individual entities, including A7 LLC and Old Vector LLC, the issuer of the ruble-backed A7A5 token, to the broader network and its payment intermediaries. The new SDN entry lists Russia, Kyrgyzstan, Nigeria and Zimbabwe as jurisdictions of concern and contains no digital-currency addresses. Treasury separately reiterated that A7A5 remains blocked property because its issuer, Old Vector, is sanctioned.

What applies now, and what is still a proposal?

The distinction matters immediately for banks, exchanges and payment firms. OFAC's blocking requirements apply now; FinCEN's transfer ban does not.

Under the OFAC action, A7 Network property in the United States or held or controlled by U.S. persons must be blocked and reported, including property involved in transactions by sub-agents acting on the network's behalf. Entities owned 50% or more — directly, indirectly or in aggregate — by blocked persons are themselves blocked. Transactions involving blocked property are generally prohibited for U.S. persons unless authorized or exempt.

FinCEN's proposed rule, issued under the Combating Russian Money Laundering Act, would prohibit sending or receiving funds, including convertible virtual currency, involving identified sub-agents — including transfers to or from accounts or crypto addresses administered by or for them. The proposal sets no effective date. Public comments are due 30 days after publication in the Federal Register.

The covered universe includes banks and money services businesses, and crypto exchanges operating as money transmitters fall into the latter category under FinCEN's existing guidance, subject to applicable exemptions. FinCEN describes sub-agents as companies operating outside the United States that A7 controls. The draft regulatory text names Galadriel Trading FZCO, Gimli Trade LLC-FZ, Hydrofusion Resources FZ-LLC, Pearl Bridge, Power Sphere LLC-FZ and Sigizmund FZCO, plus other entities FinCEN identifies later.

How would compliance work in practice?

FinCEN proposes supplying an updated sub-agent list through its secure FI-Portal and limiting the prohibition to identified entities. Institutions would apply risk-based due diligence and screening, notify affected parties with whom they hold a direct commercial relationship, and document those notifications. The proposal adds no reporting requirement beyond existing law.

For incoming crypto transfers that cannot be stopped before receipt, the rule offers a compliance path: block the assets where other authorities require it, or reject the transaction by denying the intended recipient access and returning the assets to their origin. OFAC blocking obligations take priority — the provision is not permission to return sanctioned property.

An accompanying FinCEN alert describes how sub-agents appear as paying parties on invoices and send payments from non-Russian bank accounts, concealing sanctioned customers. It flags exposure to A7A5 or wrapped versions of the token, stablecoin payments to suspected sub-agents, and unexplained surges in over-the-counter crypto activity in jurisdictions linked to A7. The agency cautions that no single red flag establishes suspicious activity and asks institutions to reference "FIN-2026-A7NETWORK" in relevant suspicious activity reports.

Why the token ledger is not the whole system?

A7's architecture separates a customer's claim on the network from the payment a supplier ultimately receives. In Open Source Centre's analysis of leaked documents, Russian clients buy bills of exchange — credit with A7 — while foreign companies execute supplier payments. FinCEN's alert describes A7A5, which operates on Tron and Ethereum, as an internal balancing ledger that mirrors foreign fiat payments rather than as the settlement rail itself.

That structure creates a visibility gap with direct compliance consequences: a bank need never encounter A7A5 to process the foreign-currency side of the arrangement. Access to banks and foreign liquidity is therefore a separate dependency from access to crypto exchanges. FinCEN also describes conversion of A7A5 into USDT and then fiat as one settlement route, though these layers should not be read as a mandatory sequence for every payment.

For compliance teams, the immediate workload is OFAC screening against the new SDN entry, with the sub-agent transfer prohibition still subject to the Federal Register comment window before it binds.
