Mexican authorities have intensified operations against the Jalisco New Generation Cartel (CJNG) in 2026, following the February death of founder Nemesio “El Mencho” Oseguera during a military action. Coordinated efforts with DEA intelligence have produced multiple high-profile arrests, including Ramón Álvarez Ayala (“R1”) in July, regional coordinators in September and October, and Rafael Álvarez Ayala (“R2”), leader of the “Los Rs” cell, on November 8 in Zapopan after a shootout that also netted 19 associates. Additional detentions of Sinaloa Cartel regional figures occurred in Chiapas on November 11. These developments, driven by U.S.-Mexico information sharing, extradition warrants, and pressure on extortion and trafficking networks, shape trader assessments of remaining leadership targets through year-end.
