According to a report by IndexBox confirmed by market sources, on June 2, 2026, OFAC allegedly designated four Iranian cryptocurrency exchanges as sanctioned entities. The measure is part of the tightening of sanctions on Iranian oil trade using the so-called dark fleet, comprising vessels that conceal their identity and operate outside tracking systems. As of this writing, no official publication was found in the Federal Register or on the OFAC website confirming the designation, so the information should be considered preliminary.

These sanctions would add to those already imposed on the Iranian oil sector. The dark fleet uses alternative payment methods, such as cryptocurrencies, to circumvent international financial controls. With this designation, the U.S. aims to close a key funding channel. The action aligns with the maximum pressure strategy on Iran.
