What OFAC has actually done
OFAC's Recent Actions page doesn't list Shelbit or Aban Tether. The June 2 designation of Nobitex and the other three exchanges remains the most recent confirmed move targeting Iran-linked crypto. No new designations have followed since.
The distinction matters because sanctions compliance is binary: a name is either on the list or it isn't. Without a formal designation, U.S. persons aren't legally required to block assets tied to Shelbit or Aban Tether. The June 2 action set the current standard for Iran-linked crypto enforcement, and nothing has changed it.
Where the chatter comes from
The names surface in third-party research, not official notices. Chainlabs summarized an investigation in May 2026 describing large Iran-linked flows through a Dubai-linked platform dubbed Shelbit. That summary came about a month before the Nobitex designation.
Separately, a 2025 case study by ChainArgos critiquing a TRM Labs report includes a chart titled 'USDT Deposits to Aban Tether,' describing Aban Tether as a material Iranian service provider by incoming volume. That study is older and predates the recent Treasury action.
Neither report is a government action. They're analyses that have circulated in compliance circles, enough to prompt questions but not enough to trigger blocking obligations.
Why compliance teams care anyway
Unconfirmed sanctions chatter can prompt pre-emptive risk reviews by compliance teams, but blocking obligations hinge on formal designations and existing Iran sanctions. The regulatory baseline remains unchanged from Treasury's June 2 action. That means Shelbit and Aban Tether aren't blocked entities under U.S. law — at least not yet.
Banks and exchanges might run extra due diligence on transactions touching those names, but they aren't required to freeze or block. The chatter alone doesn't change their legal duties.
For now, the absence of an OFAC designation leaves the situation
