Law enforcement and regulatory authorities have targeted the financial infrastructures of Mexican criminal organizations through coordinated operations and sanctions.

In late September 2026, Mexican military and federal forces conducted a large-scale operation across Chihuahua, Nuevo León, and Tamaulipas. This effort resulted in the arrest of a suspected financial operator for the ‘Los Metros’ faction of the Gulf Cartel. Authorities seized significant assets, including aircraft, numerous vehicles, fuel storage equipment, and approximately 500,000 liters of fuel, alleging the individual managed flows related to illegal hydrocarbon importation.

By mid-October 2026, the United States Department of the Treasury, through the Office of Foreign Assets Control (OFAC), expanded financial pressure by imposing sanctions on four individuals and 11 companies linked to the Cartel del Noreste (CDN). These sanctions target a network operating in the Nuevo Laredo region of Tamaulipas and Anáhuac, Nuevo León, that allegedly uses sectors such as construction, fuel distribution, freight transport, and the equestrian industry to launder drug trafficking proceeds and influence public contracts.

Specific targets include businessman Gamaliel Garza García and his son, Gamaliel Garza Elías. Investigations allege the construction firm CEGESA was used to secure public contracts through corrupt practices and to channel funds into political campaigns. Furthermore, the equestrian sector, specifically Club La Molienda and Cuadra San Dibanh, is cited as a mechanism for laundering illicit proceeds through horse racing. Mexico’s Financial Intelligence Unit (UIF) endorsed these actions, noting its own investigations revealed suspicious patterns including large cash movements, unusual international transfers, and inconsistencies in tax filings. In response, the government of Tamaulipas confirmed it has no active contracts with the designated entities and has instructed state agencies to prevent future dealings with them.
