Treasury adds Iran sanctions on VTB under Operation Economic Outcast

The U.S. Treasury’s Office of Foreign Assets Control designated Russia’s VTB Bank Public Joint Stock Company on 14 September for involvement in Iranian sanctions evasion. The action sits under Executive Order 13902, which targets sectors of the Iranian economy including finance, and under the Trump administration’s campaign branded Operation Economic Outcast.

VTB is Russia’s second-largest lender. It was already on the U.S. list. OFAC designated it on 24 February 2022 under Executive Order 14024 after the full-scale invasion of Ukraine, and again on 15 January 2025 under Executive Order 13662 for work in Russia’s financial services sector. The new listing adds an Iran theory of harm and, with it, a wider secondary-sanctions warning to banks that still clear through VTB.

Treasury said that over the past three years VTB opened correspondent relationships with sanctioned Iranian financial institutions and began steps to increase its presence in Tehran in January 2025. The department accused the bank of moving billions of dollars in frozen Iranian assets and of building a settlement system in Iranian rials and Russian rubles to lift bilateral trade. State Department spokesman Tommy Pigott said VTB opened offices in Iran and built banking ties with sanctioned Iranian houses.

Treasury Secretary Scott Bessent framed the listing as part of a wider squeeze on Tehran during the U.S. conflict with Iran. “Under Operation Economic Outcast, Treasury will continue to target and disrupt those who provide material, technological, or financial support that allows the Iranian regime to sustain its terrorist enterprise,” he said. He added that Treasury “will not tolerate any support to the regime and will continue to identify, expose, and isolate Iran’s enablers.” Bessent had said the previous week that Washington would sanction a large bank as part of that campaign.

The legal hook matters for third countries. Designation under E.O. 13902 for operating in Iran’s financial sector raises the risk for any foreign bank that keeps VTB accounts after the Iran listing, beyond the risk that already attached to the Russia listings. Treasury said institutions that continue to deal with VTB after this designation face more sanctions risk than before and should cut the relationship. Officials from the department are meeting global banks this week on Iranian revenue streams. China is among the jurisdictions that have kept some VTB business and now sits closer to a secondary-sanctions argument.

The listing does not, by itself, freeze assets that were already blocked under the 2022 and 2025 actions. What it changes is the story Treasury can tell about VTB: not only a Russian state bank in a war economy, but a channel for Iranian funds and trade during a live conflict. That story is meant to travel into compliance committees in Dubai, Hong Kong, Istanbul and Beijing, where the 2022 listing had already been priced in.

VTB has spent four years finding workarounds after its first U.S. designation. Correspondent ties in rials and rubles are one such workaround. A physical step into Tehran is another. Treasury’s account of “billions” in frozen Iranian assets being moved is the claim that will be tested by banks asked to unwind leftover VTB lines. The department did not publish a transaction-level annex with the press release.

For Moscow the listing is additive rather than new isolation. For Tehran it is one more sign that Washington intends to treat any large bank that rebuilds Iran’s cross-border payments as a target, even when that bank is already under the heaviest Russia sanctions the United States maintains. The next test is whether a non-Russian bank with a VTB book changes behaviour this week after the meetings Treasury has scheduled.
