The U.S. Treasury Department has launched a sweeping campaign to cut Iran off from global financial networks, putting cryptocurrency directly in the line of fire. The move adds digital assets to a broader sanctions strategy covering several sectors tied to Iran’s economy and revenue channels.

Operation Economic Outcast was announced on August 24 as a new U.S. campaign targeting the financial networks that Washington says support the Iranian regime and the Islamic Revolutionary Guard Corps (IRGC).

The Treasury identified five sectors where the risk of sanctions will increase: digital assets, technology, gold, aviation, and shipping.

The key aspect for the crypto industry is the new sectoral determination that sanction exempts Iran’s digital-asset economy. The determination now permits OFAC to designate foreign persons that provide or are involved in certain services to the digital-asset sector in Iran, operating from anywhere.

The Treasury stated that Iran has been increasingly resorting to cryptocurrencies to defy conventional financial sanctions. The department has singled out dealings in digital assets in relation to IRGC and Iranian regime insiders.

However, it doesn’t imply that all Iranian cryptocurrency transactions are banned. In contrast, it provides U.S. authorities with a wider framework to pursue certain individuals, companies, and networks that engage in activity under the sanctions.

The new drive may result in further vulnerabilities for crypto exchanges, custodians, payment processors and any other affiliate companies.

Companies could apply more rigorous wallet screening and transaction monitoring to vouch for sanctioned people or entities. U.S. sanctions may also apply to foreign companies for their knowledge of Iranian parties engaged in transactions that would otherwise be eligible to be undertaken by them.

The campaign follows U.S. crackdown on crypto networks affiliated with Iran. Earlier this year, 2026, a series of incidents aimed at Iranian exchanges, digital-asset wallets that were officially accused of transacting on behalf of sanctioned persons, and intermediaries.

Treasury’s recent step further heaps pressure on that, as it officially starts applying its new sanctions on Iran across digital assets and other sectors, including technology and aviation, and shipping.
