The US Treasury is expanding sanctions enforcement against Iran under a new initiative called Operation Economic Outcast, targeting five sectors including digital assets, aviation, and shipping. Treasury Secretary Scott Bessent said the US has already seized roughly $1 billion in Iranian-linked digital assets as part of the effort.
Treasury Secretary Scott Bessent put airlines, shipping companies, and crypto platforms on notice this week, warning that the US is expanding its sanctions apparatus to cut off Iran's remaining financial lifelines. Digital assets sit near the top of the target list.
Bessent's comments on September 2 followed the launch of Operation Economic Outcast, a sanctions initiative rolled out on August 24 that covers five sectors tied to the Iranian regime: digital assets, aviation, shipping, technology, and gold. The goal is to cut off resources flowing to Iran's military apparatus, specifically the Islamic Revolutionary Guard Corps.
What Operation Economic Outcast targets
The initiative gives the Office of Foreign Assets Control new authority to pursue anyone, anywhere, who provides support or services in the targeted sectors. Airlines are a prominent focus. Iranian carriers Mahan Air and IranAir have been under US sanctions for years, but the new framework extends the threat to the companies that keep their operations running — fuel suppliers, maintenance crews, and leasing companies.
Digital assets as a core sanctions pillar
Bessent highlighted that the US has already seized approximately $1 billion in Iranian-linked digital assets, a figure that underscores how seriously Washington views crypto as a sanctions-evasion tool. Iran has long been accused of using digital currencies to move money outside the reach of traditional banking restrictions, and those accusations are now translating into enforcement actions.
Digital assets stand as one of the five core sectors in Operation Economic Outcast, a co-equal pillar alongside aviation and shipping rather than a side note in a broader package. As a result, OFAC's expanded authority means even indirect facilitation of transactions linked to sanctioned Iranian entities could trigger enforcement.
A grace period before penalties
One notable aspect of Bessent's comments is the implicit grace period. The Treasury's approach appears designed to give third-party entities — foreign banks, airline lessors, crypto exchanges — time to voluntarily disengage from Iranian-linked activities before facing penalties. Exclusion from dollar-denominated transactions is the central threat backing that warning.
The maritime angle is particularly relevant given Iran's history of using ship-to-ship transfers and flag-switching to obscure oil shipments. Pairing maritime enforcement with digital asset enforcement creates a two-pronged approach: tighten the physical supply chain while closing digital financial escape routes at the same time.
