The United States Treasury imposed fresh sanctions on Oct. 1 against the A7 Network, a Russian shadow banking system utilized by Iran and sanctioned businesses to evade international financial restrictions.
Washington announced a new round of economic restrictions aimed at Russia’s A7 financial services firm, which regulators describe as a sprawling global network of shell companies moving funds for sanctioned enterprises. While framed by officials as an aggressive squeeze on Tehran’s economy, the immediate operational focus rests on a payments architecture built inside Russia. Separate reporting has placed the firm at the center of workarounds designed to bypass penalties stemming from the invasion of Ukraine, and European authorities have previously examined its activities.
Treasury Secretary Scott Bessent Details the Crackdown on A7 Network
U.S. Treasury Secretary Scott Bessent announced the restrictions in a press release, positioning the move as part of an ongoing campaign to shut down illicit financial pathways. The action falls under Operation Economic Outcast, a drive Bessent unveiled in August that has focused on regional lenders and Iranian airlines while leaving major global institutions untouched.
“Today’s action targeting A7 continues Treasury’s unprecedented efforts to isolate Iran and its financial enablers and sends a clear message that if you facilitate illicit finance for America’s adversaries, you will lose access to the U.S. financial system.”

To dismantle the infrastructure, the U.S. Treasury’s Financial Crimes Enforcement Network proposed barring transactions involving A7’s subagents and issued alerts to help institutions spot connected activity. Simultaneously, the Treasury’s Office of Foreign Assets Control designated the network as a significant transnational criminal organization.
Leadership, Scale, and Operations of the Russian Shadow Banking System
The shadow network is led by Ilan Mironovich Shor, whom regulators identify as a sanctioned and convicted criminal fraudster
. State-owned Russian lender Promsvyazbank, which maintains close ties to the military, also directs the operation, helping Russian entities skirt restrictions since 2024.
To mask illicit payments as ordinary commercial trade, the network relies on subagents in third-party jurisdictions who falsify import-export records, trade documents, and goods descriptions. According to the U.S. Treasury, the scale of this activity reached staggering proportions by January 2026.
A7 claimed to process more than 2,000 transactions daily for Russian entities, totaling 81.44 billion euros ($91.5 billion) in 2025. This volume accounted for roughly 13% of Russia’s foreign trade transactions that year.
Connections to Iran, the IRGC, and Sanctions Evasion
Beyond assisting Moscow, the shadow banking architecture provided critical financial channels for Tehran. The network facilitated Iranian oil sales and weapons procurement, linking Russian trade workarounds directly to the Middle East.
“The same A7 Network Sub-Agents that enable Russian illicit finance created pathways for other actors, including the Central Bank of Iran, the IRGC, and Iran-backed terrorist organizations, to move funds through the international financial system.”

The action follows a series of related measures. On September 29, the U.S. targeted 13 individuals and entities across Russia, China, Hong Kong, and Pakistan for supporting Iranian weapons procurement. Weeks earlier on September 18, President Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, which expanded restrictions on Moscow and extended the Iran Sanctions Act for an additional five years.
Treasury Targets Firm for Iranian Connections
Industry experts note that the strategic pairing of Russian circumvention tools with Iranian targets reflects a specific enforcement calculus at the Treasury Department. Jeremy Paner, a partner at Hughes Hubbard & Reed, observed that the firm was pursued specifically because of its Middle Eastern ties rather than its Ukraine-related workarounds alone.
“It’s a Russian sanctions circumvention network that is targeted because of its connections to Iran, not for circumventing Russian sanctions.”

Paner added that an Iranian connection seems necessary to draw Washington’s attention to a circumvention network, even when targeting Russia. The network has faced regulatory scrutiny previously; last August, authorities named the crypto exchange Garantex Europe OU for purportedly moving $100 million linked to cybercriminals and ransomware groups.
