US Treasury's Operation Economic Outcast targets Iran's crypto use for sanctions evasion, building on $131M USDT freeze in July and $344M in April. Bitcoin near $79k
The U.S. Treasury Department launched Operation Economic Outcast, a campaign to cut Iran off from international financial networks including cryptocurrency activity that officials say supports sanctions evasion and the Islamic Revolutionary Guard Corps.
President Donald Trump directed the campaign, Treasury said in an announcement. The department plans to pursue people, companies and intermediaries that help Iran sell oil, move money or avoid existing restrictions. Officials said they had already mapped facilitators and financial channels used by Tehran.
Digital assets form a named part of the campaign because Treasury says Iranian officials and connected groups increasingly use cryptocurrency to conduct transactions outside traditional banks. The Office of Foreign Assets Control has authority to sanction people operating in Iran's crypto sector regardless of their location, the department said.
A person does not become sanctioned solely because Treasury announced the campaign. OFAC must still designate the person or entity under U.S. authority, after which property under U.S. jurisdiction would generally be blocked. American individuals and companies are prohibited from providing funds or services to designated parties.
For exchanges, custodians and payment providers, a new designation may require updates to wallet-screening systems and customer controls. Non-U.S. companies may face sanctions exposure when they knowingly facilitate dealings involving blocked Iranian parties.
Operation Economic Outcast follows several U.S. actions against Iran-linked exchanges and wallets during 2026.
On Aug. 7, OFAC sanctioned Shelbit and Aban Tether. The agency also designated Iranian national Siavash Kayvanpour after alleging they helped move funds connected to sanctioned parties. Treasury said IRGC-linked addresses sent more than $1 million in cryptocurrency to Shelbit, while wallets connected to the exchange allegedly transferred more than $2 million to IRGC-controlled addresses. Kayvanpour-linked wallets sent more than $2 million to Nobitex, Iran's largest crypto exchange, Treasury alleged. Shelbit's former management denied knowingly participating in sanctions evasion.
OFAC separately accused Aban Tether of processing funds involving Nobitex, Wallex, Bitpin and Ramzinex. The four Iranian exchanges had been sanctioned in June after U.S. officials alleged they helped restricted entities use the digital asset market.
In July, U.S. authorities froze $131 million in USDT held across four Tron wallets linked by Treasury to Iran's central bank. Treasury confirmed the freeze but did not explain how the funds had been obtained or what transactions the holders intended to conduct.
An earlier April action resulted in approximately $344 million in USDT being frozen across two Tron addresses that American authorities linked to Iranian networks. Tether enforced the restriction through controls built into the stablecoin.
Centralized stablecoins give issuers a direct way to freeze assets held in named addresses. Bitcoin does not contain the same issuer-controlled function, so blocking BTC generally requires control over private keys or cooperation from a custodian.
Treasury's actions have also covered alleged Bitcoin use outside Iran's exchange sector. On July 29, OFAC sanctioned two insurers after accusing HormuzSafe Marine Services Authority of accepting Bitcoin and other digital assets to avoid restrictions and generate revenue for the IRGC. The public designation did not include wallet addresses, transaction hashes or payment totals.
Bitcoin showed little immediate reaction to the Treasury campaign, trading around $79,000 after reaching an intraday high near $80,000. The level remains a psychological barrier after the cryptocurrency's recovery from prices below $65,000 earlier in August.
Before the Treasury announcement, BTC had come under pressure as Trump escalated a trade dispute with Canada. The president threatened 50% tariffs on Canadian-made vehicles, auto parts and steel beginning Jan. 1, 2027, while Canada said it would respond with tariffs on U.S. goods.
Currency markets reacted more clearly. The U.S. dollar index rose 0.17% to 98.99 after the Iran measures and Canadian tariff announcement, Reuters reported. The Canadian dollar fell 0.61% against its U.S. counterpart. Bitcoin later recovered to approximately $78,993, up about 2.1% during the session.
