The United States has taken a major new step in its pressure campaign against Iran. The US Treasury has targeted the UAE operations of Egypt’s Banque Misr over alleged links to Iranian shadow banking networks. At the same time, Treasury Secretary Scott Bessent has said that the US may impose new secondary sanctions on Iran-linked banks every week.
The move shows that Washington now wants to focus more closely on the banks and financial companies that help Iran move money outside the country. The aim is simple: make it harder for Tehran to access US dollars and the wider global financial system.
The Banque Misr action is part of a new US campaign called Operation Economic Outcast. Treasury launched the campaign on August 24 with the goal of cutting Iran off from financial links across the world. The latest action against Banque Misr UAE came on August 28.
Why Banque Misr UAE Was Targeted
The US Treasury says Banque Misr UAE was an important route for Iran to gain access to US dollars. Treasury estimates that between January 2024 and June 2026, the UAE operations processed about $1.8 billion for 103 companies that may have been part of Iranian shadow banking networks.
Treasury says some of these companies appeared to act as front companies for Iran’s Ministry of Defense and the Islamic Revolutionary Guard Corps. It also said some customers helped move money for Iran’s Supreme Leader, Mojtaba Khamenei.
These are US government allegations. The action does not mean that every transaction handled by Banque Misr UAE was illegal or connected to Iran. The US case focuses on the bank’s alleged role in a wider network that helped Iranian money move through the international financial system.
What Is Shadow Banking?
Shadow banking may sound complex, but the basic idea is quite simple. It refers to financial activity that takes place outside normal and open banking channels.
Iran has faced broad US sanctions for years. These rules make it very hard for Iranian banks and companies to use the US dollar system directly. As a result, Iran can use companies in other countries to move money, receive payments and hide the real source of funds.
These networks can use trading firms, shell companies, banks and money exchanges in several countries. A payment may pass through more than one country before it reaches its final destination.
The US Treasury says such networks help Iran earn money abroad and maintain access to international finance despite US sanctions. The department also says these networks can help with weapons purchases and support for Iranian regional groups.
The UAE Has A Key Role
The UAE is an important financial centre for the Middle East. It has strong trade links with Asia, Africa, Europe and the Gulf. That makes its banks useful for international companies, but it can also make the country attractive to groups that want to hide the source or destination of money.
This is one reason the Banque Misr case matters beyond one Egyptian bank.
The US Treasury says the UAE operations of Banque Misr became a key route for Iranian access to dollars. By targeting that route, Washington wants other banks to become much more careful about customers and transactions linked to Iran.
The message is also aimed at banks outside the UAE. Financial institutions may now face greater pressure to check where Iranian-linked money comes from and where it goes.
This Is Not A Ban On All Banque Misr Operations
An important detail is that the US action is focused on Banque Misr UAE, not the entire Banque Misr group.
Banque Misr is Egypt’s second-largest bank. The US proposal concerns its UAE operations and their access to US financial institutions. Egypt’s central bank has said the measure applies to the UAE operations and not to Banque Misr’s other branches.
The US proposal seeks to remove Banque Misr UAE’s correspondent banking access to US financial institutions. In simple terms, this can make it much harder for the affected operations to use US banks for dollar transactions.
The proposal also seeks to stop US financial institutions from maintaining correspondent accounts for Banque Misr UAE.
Why Access To The Dollar Matters
The US dollar is at the centre of global trade and finance. Many international payments pass through US banks even when the companies involved are not American.
This gives Washington a powerful tool.
A foreign bank does not have to be based in the US to feel the effect of US financial rules. If it loses access to US correspondent banks, its ability to handle dollar payments can fall sharply.
For a bank, this can create serious business problems. It may face higher costs, fewer international partners and greater pressure from other banks that do not want to take a sanctions risk.
That is why secondary sanctions can have an effect far beyond the company that receives the original US action.
Bessent Warns Of Weekly Sanctions
The biggest development may not be the Banque Misr case itself. It is the warning from Treasury Secretary Scott Bessent that more sanctions could come each week.
Bessent said the Treasury is likely to announce new secondary sanctions on a weekly basis, with banks as an early focus. He said the next step could involve cutting an institution off from the dollar-based financial system.
His message to banks is direct. Financial institutions should not handle Iranian money or help the Iranian government avoid US sanctions.
Bessent also plans to use a meeting of G20 finance ministers and central bank governors to push other countries to reduce economic links with Iran. He has warned that institutions that continue such ties could face secondary sanctions.
China Could Become The Bigger Test
The next major question is China.
China has been a major buyer of Iranian oil, and this has led to calls for the US to target Chinese companies or banks that help Iran earn oil revenue.
Bessent, however, has rejected the argument that the US must immediately target major Chinese companies. He said US action has already reduced Iranian oil purchases by China and reduced the amount of Iranian oil held on tankers.
Still, China remains an important test for the US campaign.
If Washington starts to target a major Chinese bank, the effect could be much larger than the Banque Misr case. It could create a serious dispute between the US and China and raise wider questions about global trade, oil payments and dollar finance.
What This Means For Other Banks
The new policy could make banks across the Middle East and Asia more careful with Iran-linked clients.
Banks may review old accounts, ask for more documents and avoid customers that appear connected to Iranian trading networks. Some may decide that Iran-related business is not worth the risk.
This is one of the main goals of secondary sanctions. Washington does not need to sanction every bank itself. The threat of losing access to the US financial system can push banks to change their own behaviour.
That could make it harder for Iran to move oil revenue, pay suppliers and access foreign currency.
A Wider Financial Pressure Campaign
The US move against Banque Misr UAE is therefore more than a single bank case. It is part of a wider attempt to close the financial routes that Iran uses to operate under sanctions.
Treasury’s campaign started on August 24 under the name Operation Economic Outcast. The department has described it as a major effort against Iran and the companies, people and financial channels that support its economy.
The August 28 action shows how the campaign may work in practice. First, Washington identifies a financial link. Then it targets the foreign institution that provides that link. Finally, the US warns other banks that similar activity could bring the same result.
What Happens Next
The next few weeks will show how serious this new policy is.
If the US follows through with weekly secondary sanctions, more banks and financial companies could face pressure. Banks that have links to Iranian money may reduce their exposure even before Washington names them.
For Iran, that could mean higher costs and fewer options for international payments. For banks, it means a difficult choice between Iran-related business and access to the US financial system.
The Banque Misr UAE case has therefore set an important precedent. The US has shown that it is ready to target foreign banking operations that it says help Iran move money through the global system.
With Bessent now warning of new action every week, the pressure on Iran’s financial network is likely to grow. The key question is no longer whether Washington will target banks. It is which bank will come next, and how far the US is ready to go to cut Iran out of global finance.
