U.S. Treasury Targets A7 Shadow Banking Network in Major Sanctions Action

Treasury Targets the A7 Network

The Office of Foreign Assets Control designated the A7 Network as a significant transnational criminal organization.

According to Treasury, A7 was created and backed by sanctioned individuals and developed a global network of companies designed to disguise restricted payments as ordinary commercial transactions.

The network has ties to Russia and has also been used by Iran, including the Islamic Revolutionary Guard Corps, according to the U.S. government.

A Global Network of Sub-Agents

A key part of A7’s structure involves companies Treasury calls “Sub-Agents.”

These businesses operate in third countries and can receive or send payments on behalf of the wider network. Treasury says techniques including falsified trade documents, misleading descriptions of goods and altered import-export records have been used to make transactions appear legitimate.

FinCEN’s investigation found that A7 Sub-Agents processed more than $17 billion globally between January 2025 and June 2026.

FinCEN Proposes Tougher Restrictions

Alongside the sanctions, the Financial Crimes Enforcement Network proposed a new rule targeting transactions involving A7’s Sub-Agents.

If finalized, the measure would prohibit covered U.S. financial institutions from transmitting funds involving those companies.

The restriction would apply not only to conventional transfers but also to convertible virtual currencies, making the proposal relevant to both traditional banking and digital assets.

The public will have an opportunity to comment on the proposal before it becomes final.

Financial Institutions Receive New Warning Signs

FinCEN also issued an alert to banks and other financial institutions to help them identify suspicious transactions associated with A7.

The guidance focuses on how foreign companies can be used to provide access to international payment systems while concealing the individuals or organizations ultimately behind transactions.

This gives financial institutions additional indicators they can use when deciding whether activity should be reported.

Iran Links Expand the Case

Treasury says the A7 network wasn’t used solely for Russian financial activity.

Its investigation identified pathways involving Iran’s Central Bank, the IRGC and other Iranian-linked entities. Some A7 Sub-Agents were also connected with Iranian oil sales and weapons procurement.

One Sub-Agent and a related company received nearly $140 million from entities involved in Iranian sanctions evasion, according to Treasury.

Digital Assets Are Part of the Network

The enforcement action also highlights A7’s use of cryptocurrency infrastructure.

Treasury specifically referenced A7A5, a ruble-backed digital token associated with the network. U.S. officials say the token was developed to facilitate international transactions outside conventional financial channels and generate revenue for sanctioned infrastructure providers.

The October action therefore reaches beyond traditional banks and front companies into the growing role digital assets can play in cross-border finance.

Immediate Sanctions, Proposed Banking Rules

The distinction between the two October 1 actions is important.

OFAC’s designation means relevant A7 property and interests in property within U.S. jurisdiction are blocked, with U.S. persons generally prohibited from conducting covered transactions.

FinCEN’s broader prohibition involving Sub-Agent fund transfers is still being proposed.

Together, the measures show how U.S. sanctions enforcement is increasingly targeting not only individual companies or officials but also the financial networks, intermediaries and digital infrastructure used to move money around existing restrictions.
