The United States has expanded its economic pressure campaign against Iran with sweeping new sanctions targeting 27 Iranian airlines and other organizations accused of supporting Tehran’s aviation and financial networks.
The US Treasury Department announced the measures on September 8 as part of President Donald Trump’s broader effort to isolate Iran from the international financial system.
The latest action falls under Operation Economic Outcast, a campaign launched by Treasury Secretary Scott Bessent in August with the stated goal of cutting off the economic channels that support the Iranian government and its Islamic Revolutionary Guard Corps.
Treasury said the newest sanctions target Iran’s remaining active airlines as well as foreign companies and intermediaries that allegedly help Tehran obtain aircraft, aviation equipment and other sensitive technology.
27 Iranian Airlines Targeted
The Treasury Department identified 27 Iranian airlines in the latest sanctions package.
The list includes Iran Air Tour, Iran Aseman Airlines, Kish Airlines, Qeshm Air, Sepehran Airlines, Varesh Airlines, Zagros Airlines and several other carriers operating in Iran.
US officials said Iranian commercial aviation networks have been used by the Iranian regime for activities including the transportation of personnel, weapons and other cargo.
The sanctions also target companies and intermediaries outside Iran that Washington says have helped sanctioned Iranian airlines operate or obtain US-origin aircraft and technology.
Treasury Warns Foreign Businesses
Bessent warned companies and individuals that continue supporting sanctioned Iranian airlines could face serious consequences.
Under the US campaign, foreign businesses that provide services such as aircraft transfers, cargo support or sales representation to sanctioned Iranian carriers could face restrictions on their access to the American financial system.
The Treasury Department said the latest measures are designed to make it more difficult for Iran to maintain international aviation connections while also disrupting procurement networks.
The department also suspended three existing aviation authorizations, including provisions involving certain overflights and the use of US-origin or US-controlled aircraft for flights into Iran.
What Is Operation Economic Outcast?
Operation Economic Outcast was formally launched by the Treasury Department on August 24.
Bessent described the campaign as a broad economic operation designed to target Iran’s financial connections around the world.
The administration says the campaign will focus on networks involved in Iranian oil sales, sanctions evasion, money laundering and other activities that Washington believes generate revenue for the Iranian government and the IRGC.
The United States has also warned international businesses that continued dealings with targeted Iranian entities could expose them to secondary sanctions and restrictions on access to US financial institutions.
US Pressure Extends Beyond Aviation
The airline sanctions are only one part of the administration’s broader economic campaign against Tehran.
In recent weeks, Washington has also targeted financial institutions, oil-related networks and companies accused of helping Iran move money internationally.
Treasury has specifically sought to disrupt financial channels connected to Iranian oil revenue and sanctions evasion.
The administration’s strategy is intended to increase the economic cost of maintaining Iran’s current policies while limiting Tehran’s ability to access international markets and financial services.
Iran Faces Increasing Economic Pressure
The latest sanctions come as tensions between Washington and Tehran remain high.
The US has combined economic measures with military pressure as the conflict continues, creating additional uncertainty for Iran’s economy and international trade.
The impact could extend beyond airlines because aviation companies rely heavily on access to aircraft, spare parts, financing, insurance and international service providers.
Restrictions on those networks could make it increasingly difficult for Iranian carriers to maintain operations and international connections.
Sanctions Could Reshape Iran’s International Connectivity
By targeting virtually the entire Iranian airline sector, Washington is seeking to close another channel through which Iran remains connected to the global economy.
The Treasury Department said foreign companies assisting sanctioned Iranian airlines should expect heightened scrutiny and potential penalties.
The campaign reflects the Trump administration’s broader strategy of using US financial power to pressure Tehran and force international businesses to choose between maintaining relationships with Iran and preserving access to the US financial system.
