Shibbir Ahmed, New York — The United States has imposed new sanctions on Russia’s VTB Bank, accusing the major financial institution of helping Iran evade U.S. sanctions and establishing correspondent banking relationships with sanctioned Iranian banks. The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) announced the action on September 14 under the administration’s Operation Economic Outcast, a campaign aimed at disrupting the Iranian regime’s financial networks and sources of revenue.

“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,” Treasury Secretary Scott Bessent said. Bessent added that the United States would continue identifying, exposing and isolating individuals and institutions that support the Iranian regime.

VTB Accused of Expanding Ties With Iran

According to the Treasury Department, VTB Bank, one of Russia’s largest financial institutions, has expanded its banking presence in Iran in recent years as Moscow and Tehran have sought to deepen economic and trade ties.

U.S. authorities said VTB established correspondent banking relationships with Iranian financial institutions already under sanctions and began taking additional steps to expand its presence in Tehran in January 2025.

The Treasury Department also accused the bank of helping establish a settlement mechanism using Iranian rials and Russian rubles through correspondent accounts, with the aim of facilitating bilateral trade. U.S. officials further alleged that VTB took steps to move billions of dollars in frozen Iranian assets.

Operation Economic Outcast

The Treasury Department announced Operation Economic Outcast on August 24, describing the campaign as an effort to sever the remaining economic lifelines supporting the Iranian regime. The operation focuses on financial networks involved in oil smuggling, sanctions evasion and the financing of Iran’s security apparatus, terrorist proxies and other affiliated networks.

Washington has warned foreign financial institutions that continuing significant business with sanctioned Iranian entities could expose them to secondary sanctions and potentially restrict their access to the U.S. financial system. The Treasury Department said it is also working with partners in the European Union, the United Kingdom and Gulf countries to target financial channels connected to Iran.

VTB Already Under U.S. Sanctions

The latest action is not the first time VTB Bank has been targeted by the United States. OFAC previously designated VTB in January 2025 under sanctions authorities targeting Russia’s financial sector. The bank was also sanctioned in February 2022 over its ties to the Russian government and its operations in Russia’s financial services sector. The new designation adds Iran-related sanctions exposure to the bank’s existing restrictions.

Assets Blocked

Under the latest action, all property and interests in property belonging to VTB Bank that are located in the United States or held by U.S. persons are blocked and must be reported to OFAC. U.S. persons are generally prohibited from conducting transactions involving the blocked property unless authorized by OFAC or covered by an applicable exemption. The restrictions also extend to entities that are owned, directly or indirectly, 50% or more by one or more blocked persons.

Foreign financial institutions engaging in certain significant transactions involving designated entities may also face the risk of secondary sanctions, including restrictions on their ability to maintain correspondent or payable-through accounts in the United States.

The Treasury Department said the latest action sends a broader warning to foreign banks and businesses that facilitate Iran’s efforts to circumvent U.S. sanctions. Washington is expected to continue targeting financial institutions and other entities that it says provide Iran with access to international financial networks.

Shibbir Ahmed, WASHINGTON DC — The United States is preparing to intensify economic pressure on Iran with a new campaign of weekly secondary sanctions, Treasury Secretary Scott Bessent said Monday, as military tensions between Washington and Tehran sharply escalated.

Bessent told Reuters that the U.S. Treasury Department is expected to announce new secondary sanctions every week, beginning with measures targeting banks and financial institutions that help Iran maintain access to international markets.

The planned measures are designed to further restrict Iran’s access to the global financial system and increase pressure on institutions and countries that continue doing business with Tehran. The announcement comes as the United States and Iran have entered their most serious period of renewed hostilities in weeks.

U.S. forces struck two Iranian launchers on Larak Island on Sunday after American forces identified what U.S. officials said were preparations by Iran’s Islamic Revolutionary Guard Corps to launch rockets carrying sea mines into the Strait of Hormuz.

Iran responded by launching missiles toward U.S. military bases in Jordan, according to U.S. and Iranian officials. The attacks marked the first direct exchange of fire between the two sides in about a month. President Donald Trump on Monday warned that the United States would respond forcefully to Iran’s attacks. The latest escalation has raised concerns about a wider regional conflict, particularly because of the strategic importance of the Strait of Hormuz, a critical route for global oil shipments.

Financial Pressure on Iran

The planned sanctions would expand the use of so-called secondary sanctions, which can penalize foreign companies, banks and other institutions that conduct certain business with Iran even when those entities are not based in the United States.

Bessent said the campaign would initially focus on banks and could increasingly target institutions that help Iran move money through the international financial system. The Treasury secretary’s announcement represents a further expansion of the administration’s economic campaign against Tehran.

The United States has already broadened the range of Iranian economic activities that could expose foreign businesses to secondary sanctions, including sectors such as digital assets, gold, technology, aviation and shipping.

Last week, the Treasury Department launched what it described as an unprecedented campaign against Iranian financial networks, targeting channels used by Tehran to generate revenue, evade sanctions and finance activities opposed by Washington.

Military Tensions Add to Economic Pressure

The new sanctions strategy comes as diplomatic and military tensions continue to worsen. The U.S. military said its strike on Larak Island was aimed at preventing Iran from deploying sea mines in the Strait of Hormuz. Iran has rejected the U.S. justification and warned that it would respond to further attacks.

Following the Iranian missile launches toward U.S. forces in Jordan, Trump said the United States would respond strongly. Reuters reported that the exchange of attacks represents a renewed escalation after a period in which the two sides had avoided direct military confrontation.

The conflict has also affected global energy markets. Brent crude oil futures settled more than 2.5% higher on Monday after the latest U.S.-Iran military exchanges, reflecting renewed concerns over the security of oil shipments through the Strait of Hormuz.

Pressure on Iran’s Financial Lifelines

The Trump administration has increasingly focused on Iran’s financial networks as part of its broader strategy to weaken Tehran’s ability to fund its government, military and regional activities.

The planned weekly sanctions would represent a significant escalation because foreign financial institutions could face increasing pressure to choose between maintaining business relationships with Iran and retaining access to the U.S.-dominated international financial system.

For Iran, the measures could further complicate access to foreign currency, international banking services and overseas trade. For the United States and its allies, however, the strategy carries its own risks, particularly if increased economic pressure contributes to further military escalation or disruption of global energy supplies.

With the United States preparing additional sanctions and military tensions rising, the coming days could determine whether the latest confrontation remains limited or develops into a broader regional crisis.
