The U.S. Treasury Department imposed sanctions on Nobitex, Iran’s largest cryptocurrency exchange, and three other digital-asset entities on June 18, 2026 [1].
These measures target the financial infrastructure used by the Islamic Revolutionary Guard Corps (IRGC) to bypass international restrictions. By restricting access to digital assets, the U.S. government aims to diminish Tehran's ability to fund operations and evade economic penalties.
The Office of Foreign Assets Control (OFAC) designated a total of four digital-asset entities [1]. This action follows a separate move on May 28, 2026, when the U.S. sanctioned a newly created Iranian Hormuz Authority [2]. This authority is responsible for overseeing the Strait of Hormuz, one of the world's most critical maritime corridors.
U.S. officials said the sanctions are intended to intensify economic pressure on Tehran. The strategy seeks to force Iran to relinquish control over the Strait of Hormuz and move toward a broader agreement to end hostilities with the U.S. and Israel [1, 2, 3].
Digital currency exchanges have increasingly become focal points for sanction enforcement. The U.S. government said the targeting of Nobitex is specifically designed to curb the IRGC’s ability to move funds covertly [3]. The Treasury Department continues to monitor digital-asset platforms that facilitate the movement of capital for sanctioned regimes.
These combined actions, targeting both the high-tech financial sector and the strategic maritime authority, represent a dual-track approach to isolating the Iranian economy. The U.S. government said these steps are necessary to push the Iranian leadership toward a comprehensive diplomatic resolution [1, 2].
“The U.S. Treasury Department imposed sanctions on Nobitex, Iran’s largest cryptocurrency exchange.”
The simultaneous targeting of cryptocurrency gateways and maritime administration indicates a U.S. strategy to close both modern and traditional loopholes used by Iran. By attacking Nobitex, the U.S. is acknowledging the role of blockchain technology in sanction evasion, while the sanctions on the Hormuz Authority signal that the U.S. views the Strait of Hormuz as a primary geopolitical lever to force a broader diplomatic agreement.
