Mexico Reports 70% Decline in Fentanyl Flows, 97% Drop in Illegal Border Crossings Under Sheinbaum

The Sheinbaum administration reported data indicating a 70% decrease in fentanyl flows at Mexico-U.S. crossing points and a 97% reduction in illegal border crossings under her administration's enhanced interdiction posture. The fentanyl decline figures reflect intensified customs inspections at the Port of Manzanillo and other CJNG-controlled precursor entry points, as well as the disruption of CJNG's senior logistics tier following El Tuli's February 22 killing. Analysts caution that the figures represent interdiction statistics rather than confirmed production reductions — CJNG's laboratory infrastructure in Jalisco and Michoacán remains largely intact, and Heraclio Guerrero Martínez ('Tío Lako') continues managing residual logistics networks. The data nonetheless represents a significant short-term operational win for U.S.-Mexico security cooperation and helps Mexico validate its commitment to bilateral security objectives tied to trade and tariff negotiations with Washington. El Jardinero and O3 remain at large; the long-term durability of the fentanyl disruption depends on the outcome of the succession crisis and whether CJNG reconstitutes its logistics network under new leadership.
