OFAC designates A7 Network as TCO, blocks A7A5 ruble stablecoin

US Treasury designated the A7 Network as a transnational criminal organization on Oct 1 and blocked its A7A5 ruble stablecoin, naming it as the pipe for $17B in sanctions-evasion flows used by Iran.

The U.S. Treasury's Office of Foreign Assets Control designated the A7 Network as a transnational criminal organization on Oct 1 under the banner Operation Economic Outcast, and blocked all property interests in its ruble-pegged A7A5 stablecoin. Treasury names A7 as the pipe through which $17 billion has moved between January 2025 and June 2026, with $140 million routed to Iranian sanctioned entities and $1.6 million to a company linked to Iran's weapons-procurement network.

What happened

The sb0644 release names three main targets:

  • A7 Network itself, designated as a transnational criminal organization.
  • Old Vector LLC, the Kyrgyzstan-domiciled issuer of A7A5. Treasury had already designated the entity on Aug 14, 2025; today's action adds the token.
  • Ilan Mironovich Shor, the Moldovan fugitive oligarch previously convicted in Chișinău over a billion-dollar bank fraud, named as the network's principal.

FinCEN acted in parallel: an alert to banks and virtual-asset service providers warning of A7 Sub-Agent typologies, and a Notice of Proposed Rulemaking under §9714(a) of the Combating Russian Money Laundering Act, which would prohibit U.S. financial institutions from transmitting funds to or from the A7 Sub-Agents named in the notice.

How A7A5 works

A7A5 is a ruble-collateralized stablecoin live on Ethereum and Tron. Russia's state-adjacent Promsvyazbank is named by Treasury as the reserve custodian; mint and burn route through Old Vector LLC. Each token is nominally 1:1 against the ruble.

The designation freezes any U.S.-touching counterparty exposure and effectively ends on-chain fungibility for the token with any OFAC-compliant venue — major exchanges, bridge frontends, and USD-side settlement providers must now screen and block. The token itself continues to exist on-chain — sanctions do not delete tokens — but transfers to or from U.S. persons are prohibited.

Numbers

- A7 Network throughput, Jan 2025 – Jun 2026 (Treasury) : $17B
- Flows to Iranian sanctioned entities                  : $140M
- Flows to Iranian weapons-procurement firm             : $1.6M
- Old Vector LLC prior designation date                 : 2025-08-14
- A7A5 chains                                            : Ethereum, Tron
- Reserve custodian (Treasury)                          : Promsvyazbank
- A7A5 cumulative on-chain volume (Elliptic, Decrypt)   : ~$40B

The $17B is Treasury's own figure. The $40B cumulative on-chain volume cited by Decrypt comes from Elliptic analytics and is not in the sb0644 release — attribute to Elliptic, not Treasury.

Impact

  • Stablecoin issuers and exchanges: any address holding A7A5 is now a sanctions-exposed address. Expect A7A5 to be flagged by Chainalysis, Elliptic, and TRM screening tools and dropped from any OFAC-compliant venue listings.
  • Tron and Ethereum: on-chain the token stays — the practical outcome is a progressive isolation of A7A5 to Russian and Iranian corridors.
  • FinCEN NPRM: once finalized, the §9714 rule gives U.S. banks a statutory basis for blanket refusal of correspondent flows tied to A7 Sub-Agents. §9714 has previously been used against the Bitzlato operator; this is its first application against a stablecoin issuer.
  • Secondary enforcement: EU, UK, and FATF-aligned jurisdictions typically mirror OFAC designations within days. MiCA-licensed CASPs will need to update their sanctions screening before the next weekly reporting cycle.

What to watch

  1. The SDN List additions in OFAC's daily publication — the full count of named individuals, companies, and crypto addresses matters for screening tooling to pick up every wallet. Chainalysis Sanctions, Elliptic Navigator, and TRM Chain Abuse datasets will refresh in parallel.
  2. A7A5 liquidity venues in Russia and the CIS. Successor venues to the previously-designated Garantex, and other ruble-stablecoin bridges, are the first screens to watch.
  3. The FinCEN NPRM comment window and effective date — the §9714 toolkit against a stablecoin issuer sets precedent that will shape how dollar-adjacent payment rails handle other ruble- or yuan-pegged issuers.
  4. Issuer or protocol-level reaction. Any attempt by Old Vector LLC to redeploy the token under a new issuer or new chain gets picked up by the same analytics stack — the OFAC designation attaches to the asset's identifying details, not just to the current contract.

Context

A7A5 was first described in open-source analytics in late 2025 as a workaround to the dollar-centric sanctions perimeter after the designation of Garantex in March 2025. Treasury's framing — a stablecoin not as a payment rail but as the obfuscation layer — tracks the same pattern as the Tornado Cash sanction regime: the asset is designated for how it is used. The novelty here is targeting a ruble-side, not dollar-side, stablecoin, and doing it under the §9714 Russian-money-laundering authority rather than the generic IEEPA Russia executive orders.
