Overview
- The U.S. Department of State and Treasury formally listed the Juárez Cartel and Los Viagras as Foreign Terrorist Organizations and Specially Designated Global Terrorists when their designations were published in the Federal Register on Thursday, July 16, 2026.
- Those listings immediately block property and interests in property in the United States and generally bar U.S. persons from transacting with the groups, giving law enforcement new tools to freeze assets and pursue criminal or civil cases.
- U.S. officials cited violent narco-attacks linked to the Juárez Cartel, including the 2019 Sonora massacre that killed nine U.S. citizens, and described Los Viagras as a Michoacán-based producer and trafficker of synthetic drugs that uses extortion to control territory.
- Los Viagras leader Nicolás Sierra Santana faces a U.S. indictment in the District of Columbia and a $5 million State Department reward for information leading to his capture, steps that the new designation reinforces.
- The move builds on a Trump administration policy begun in February 2025 to widen tools against cartels, but it has increased diplomatic tensions with Mexico and could complicate cross-border cooperation even as it tightens financial pressure on trafficking networks.
