The U.S. Department of the Treasury has announced what it calls "unprecedented" measures against A7, a Russia-backed fintech and cryptocurrency firm accused of helping Iran circumvent international sanctions. The company, believed to have moved billions of dollars in defiance of Western restrictions, has been characterized as a shadow banking structure and formally designated a criminal organization.

Treasury targets Moscow-backed payment processor A7

Washington sanctioned A7, a fintech and cryptocurrency firm previously implicated in facilitating Russian efforts to bypass the financial restrictions imposed over the war in Ukraine. The Moscow-supported platform is now being targeted for allegedly enabling Iran and its proxy groups to do the same. In the official announcement, published Thursday on the Treasury's website, the department stated:

"The U.S. Department of the Treasury took unprecedented action against the A7 Network, a shadow banking network with ties to Russia used by the Iranian regime to evade sanctions."

As part of the action, the Financial Crimes Enforcement Network (FinCEN) is proposing a rule that would prohibit transfers of funds linked to transactions involving A7's subagents. FinCEN has also issued a special alert designed to help financial institutions detect and report suspicious activity connected to A7 and its affiliates, according to the press release. Because the transfer ban is proposed rather than final, it would take effect only after FinCEN completes the U.S. rulemaking process, which typically includes a public comment period; the special alert, issued alongside it, applies immediately, feeding indicators into the suspicious-activity reports U.S. financial institutions are already required to file.

Meanwhile, the Treasury's Office of Foreign Assets Control (OFAC) has designated the A7 network a "significant transnational criminal organization." The department made clear that the measures fall under Operation Economic Outcast, a campaign launched at the direction of U.S. President Donald Trump in late August of this year. At its launch, the initiative was presented as a campaign against the Islamic Republic and its enablers — "an economic onslaught against Iran's financial connections around the globe." For the digital-asset sector, the action is a reminder that U.S. financial-enforcement powers now reach stablecoin issuers and crypto payment networks operating far outside American jurisdiction.

Speaking this week, Treasury Secretary Scott Bessent emphasized that his department is dismantling the financial infrastructure that allows Iran and others to evade sanctions. He said the steps are intended to prevent such actors from moving illicit funds while undermining the integrity of the global financial system.

"Today's action targeting A7 … sends a clear message that if you facilitate illicit finance for America's adversaries, you will lose access to the U.S. financial system," Bessent said.

Americans barred from doing business with A7

Under the new measures, any assets held by A7 in the United States would be frozen, and American citizens would be prohibited from doing business with the firm and its affiliates, as the Financial Times highlighted in its coverage. An investigation published by the business daily last month found that A7 had moved nearly $7 billion through the international banking system using forged documents and front companies. The newspaper identified a couple of hundred such entities, including organizations based in the United Arab Emirates, Hong Kong, Indonesia, and Kyrgyzstan.

According to the U.S. Treasury, these subagents "form a core layer of the A7 Network's operational architecture," intended for sanctions evasion and money laundering. The department maintains that the mechanism, which also involves cryptocurrency-based methods, is tied to Russian illicit finance and has been utilized by other actors such as Iran.

The Treasury believes the Russian firm supports Iran's Islamic Revolutionary Guard Corps and Iranian proxies such as Hamas, and that it is linked to Nobitex, the designated Iranian digital asset exchange.

A7 is majority-owned by Ilan Shor, a fugitive Moldovan oligarch holding a Russian passport, and co-owned by Russia's state-controlled PSB, formerly known as Promsvyazbank. Both shareholders have been sanctioned by the West.

The company created A7A5, arguably the largest non-dollar stablecoin, now issued by a Kyrgyzstan-registered entity and allegedly backed by deposits in Russian rubles held at PSB. Dollar-pegged tokens dominate the stablecoin sector, which is what makes a ruble-backed asset of this scale stand out. Shor recently boasted that the payments platform was processing up to 2,000 transactions daily, with a total value reaching 7.5 trillion rubles in just 10 months — approximately $90 billion at the current exchange rate.

Per the Treasury's Thursday announcement, A7's transaction volume is equivalent to roughly 13% of the Russian Federation's 2025 foreign trade transactions.

Within Russia, A7 has frequently been praised as an alternative to the established payment systems controlled by the West, at a time when sanctions severely restrict Russian access to global finance. Whether the FinCEN rule is finalized, and how widely institutions apply the alert's red flags, will indicate the practical reach of the new measures.
