The U.S. Treasury Department sanctioned Iran-linked digital-asset wallets on Monday, August 24, alongside aviation, shipping, and gold networks. Five sectors in total. Officials called it an “economic D-Day” against Tehran.
Treasury Secretary Scott Bessent laid out the Trump administration’s plan at a press conference. He named digital assets, technology, aviation, gold, and shipping as the revenue streams now in Washington’s crosshairs. The move folds crypto into a multi-sector pressure campaign rather than treating it as a standalone target. That breadth is rare. It raises compliance questions for any exchange touching Iranian counterparties.
In practice, firms handling the flagged wallets face the same U.S. sanctions exposure as those dealing in sanctioned Iranian oil or gold.
“These measures broaden secondary sanctions risk for anyone foolish enough to continue conducting business with this regime—and accelerate the speed with which we pursue them,” Bessent said at the press conference, The Block reported.
Treasury, the State Department, and the military are meeting with global stakeholders, Bessent said. He added that “every country has a defined timeline to shut down activities we have identified.” He did not specify those deadlines.
Monday’s designations included a number of digital-asset addresses. Among them: wallets tied to Arman Kahzadian. Treasury said Kahzadian gained control of a wallet holding over $30,000 worth of bitcoin in 2023. The article did not publish the full address list. OFAC designation details, including the SDN entries and their effective dates, were not specified.
The push builds on a steady escalation. In June 2026, the U.S. sanctioned Iran’s largest crypto exchange, Nobitex, calling it a key player in sanctions evasion, terrorist financing, and transactions tied to Iran’s Islamic Revolutionary Guard Corps. As of May 2026, Bessent said the U.S. has seized nearly $1 billion in crypto from Iran.
The broader framing is a U.S.–Iran conflict that began last year with initial strikes that killed Iran’s Supreme Leader Ayatollah Ali Khamenei. Monday’s sanctions extend that campaign into the financial rails Treasury says Tehran relies on.
For exchanges, the practical consequence is narrower than the rhetoric suggests. A wallet on the SDN list must be frozen, not merely monitored. What remains unclear is whether Treasury will publish supplementary compliance guidance or leave firms to map the new addresses against their own user bases.
The article did not disclose the total dollar value of Monday’s designations, the full list of sanctioned individuals beyond Kahzadian, or whether Treasury or OFAC issued a separate press release with the flagged wallet addresses.
