The United States is stepping up its economic pressure on Iran, and the campaign is now getting support from Europe.
Washington launched Operation Economic Outcast on August 24, describing it as a sustained campaign to cut Iran off from the financial networks and revenue sources that keep its economy running. The US Treasury has warned companies, banks and other entities dealing with Iran that they could also face sanctions.
Now, the European Union has backed the campaign.
US Treasury Secretary Scott Bessent said on September 4 that the EU had officially joined the US-led economic pressure campaign against Iran.
The EU had already said during the G20 finance meetings that it supported additional economic pressure on Tehran, including through Operation Economic Outcast, while also calling for diplomatic efforts.
So, what exactly is Operation Economic Outcast, why is Europe supporting it and why should India care?
What is Operation Economic Outcast?
Operation Economic Outcast is a US sanctions campaign aimed at cutting Iran’s remaining economic lifelines.
The US Treasury says the operation will target the networks that help Iran earn money, move funds and evade sanctions. The first measures announced on August 24 targeted dozens of entities, individuals and vessels connected to Iran’s oil revenues, procurement networks and other activities.
A major part of the strategy is secondary sanctions.
This means the US can target foreign companies or financial institutions that help sanctioned Iranian entities. A business does not necessarily have to be based in Iran to face consequences from Washington.
For banks in particular, the risk is serious. Losing access to the US financial system can be far more damaging than losing access to the Iranian market.
That is the pressure point Washington is trying to use.
Why is the US putting more pressure on Iran?
Iran has been under US sanctions for years, so another sanctions programme may sound like more of the same. The difference this time is the scale and the stated goal.
The Trump administration wants to go after the wider network that allows Iran to keep trading despite sanctions. That includes financial institutions, oil-related businesses, shipping networks and other intermediaries.
Bessent has also indicated that further secondary sanctions are expected, meaning foreign companies that continue facilitating Iranian trade could increasingly find themselves in Washington’s crosshairs.
The US wants to make it increasingly difficult for Iran to sell its oil, receive payments and maintain access to international finance.
Why is the EU backing Operation Economic Outcast?
The EU’s involvement is important, but the wording needs some care. Brussels has not simply copied the entire US sanctions programme into European law.
The EU already has its own extensive sanctions regime against Iran. In its statement around the G20 finance meetings, the EU said it welcomed additional economic pressure on Iran, including through the US-led Operation Economic Outcast. It also said it would continue working with the US, G7 and other international partners to maintain pressure on Tehran.
At the same time, the EU stressed the need for diplomacy, regional stability and freedom of navigation through the Strait of Hormuz.
In other words, Europe is supporting stronger economic pressure while keeping the door open for negotiations.
Why does China matter so much?
There is a major weakness in any attempt to isolate Iran completely: Iran still has important trading partners. China is the biggest one.
Iran’s oil exports and the companies involved in moving that oil have become a central focus of the US pressure campaign. Analysts have pointed to China as one of the biggest tests of whether Washington can actually reduce Iran’s oil revenues.
The problem for Washington is that putting major Chinese companies or financial institutions under heavy sanctions could create a much bigger confrontation.
China is a major global economy. It is also an important trading partner for the United States.
So the question is not simply whether America can sanction Iran. It is whether Washington can pressure the countries still willing to trade with Iran without creating a much larger economic fight.
What does Operation Economic Outcast mean for India?
India has reasons to watch this very closely.
India has strategic interests in Iran, particularly around connectivity and the Chabahar port, while its economic relationship with Iran has already been affected by US sanctions.
Prime Minister Narendra Modi recently discussed expanding trade with Iranian President Masoud Pezeshkian on the sidelines of the SCO meeting, at a time when Washington is increasing pressure on countries and companies doing business with Tehran.
There is also an oil problem.
If sanctions significantly reduce Iranian oil exports, global crude prices could come under pressure. India imports most of the crude oil it consumes, so a sustained increase in global oil prices can raise the country’s import bill and add pressure to inflation and the rupee.
Indian companies involved in Iran-related trade could also face greater compliance risks if Washington expands secondary sanctions.
The US has already sanctioned India-based companies over Iran-related petroleum and petrochemical trade, showing that Indian businesses are not automatically outside the campaign’s reach.
Can this force Iran to change?
Iran is facing severe economic problems. Its currency has weakened sharply, while shortages and high inflation have added to pressure on ordinary people. But Iran has also spent decades learning how to operate under sanctions.
Economic pressure can make life harder for the government and the population without necessarily producing the political outcome Washington wants.
Iran can look for alternative buyers, payment routes and trading partners. China and other countries may also limit the impact of American sanctions by continuing selected economic relationships with Tehran.
The success of Operation Economic Outcast will therefore depend less on the number of names added to US sanctions lists and more on whether Iran’s remaining international economic channels can actually be closed.
For now, the US has the EU moving closer to its position. But China remains the much harder test.
Operation Economic Outcast FAQs

2. Why is the EU joining Operation Economic Outcast?
The EU has backed additional economic pressure on Iran, including through Operation Economic Outcast. It has also said it will continue working with the US and G7 while supporting diplomacy and regional stability.
3. Does Operation Economic Outcast affect India?
Yes. Indian companies involved in Iran-related trade could face US secondary sanctions, while higher global oil prices could affect India’s import bill, inflation and the rupee.
4. Why is China important to Operation Economic Outcast?
China is a major economic partner for Iran and an important destination for Iranian oil. If Chinese buyers and companies continue trading with Iran, completely cutting Tehran off from global revenue will be much harder.

It could increase economic pressure on Iran, but collapse is not guaranteed. Iran has extensive experience operating under sanctions and can use alternative trading partners and financial channels to reduce their impact.
