Puerto Vallarta, Jalisco, October 14, 2026 — Mexico and the United States imposed financial restrictions October 13 on four people and 11 companies allegedly linked to the Cártel del Noreste.
The U.S. Treasury announcement describes a network spanning quarter horse racing, construction, trucking, and oil and gas. Mexico’s Financial Intelligence Unit, known as the UIF, placed the same 15 subjects on its blocked-persons list.
The immediate consequence is financial: the U.S. action freezes covered assets and generally prohibits transactions involving the blocked parties unless authorized or exempt. Mexico’s measure restricts access to its financial system.
How does blocking a business network interfere with a cartel’s operations?
The intended effect is to interrupt the commercial relationships that help move money and sustain the organization. Treasury did not give a dollar value for the assets affected by Tuesday’s action.
“This action marks Treasury’s most significant effort to date to disrupt Cartel del Noreste’s financial infrastructure,” Treasury Secretary Scott Bessent said.
The official sanctions list names Gamaliel Garza García, Gamaliel Garza Elías, Pablo César Guajardo Álvarez and Francisco Javier Inzunza Partida. The listed businesses are concentrated in Nuevo Laredo, Tamaulipas, and Anáhuac, Nuevo León.
The horse-racing allegations illustrate how authorities say ordinary commercial activity can support cartel finances.
Treasury identifies Club La Molienda, a racetrack, restaurant and bar outside Nuevo Laredo, as a cartel-controlled business. It alleges that entrance fees paid by spectators and people racing their horses generate revenue for the organization, while cartel members purchase horses, including animals from the United States, to compete there.
The action follows the cartel-linked casino crackdown covered by Vallarta Daily in April. That earlier operation targeted three people and three companies, and Mexico suspended the casinos’ activities.
Construction forms another part of the new case. In its report on Treasury’s allegations, El País described accusations that Construcciones y Edificaciones Garza Elías, known as CEGESA, funneled money to favored political campaigns and obtained public contracts through corruption. A related company, COPASA, allegedly supplied materials while CEGESA performed or subcontracted the work.
Tamaulipas disputed the implication that the named businesses had contracts with its current administration. According to reports, the state said its records showed no contracts with any of the named people or companies since October 1, 2022, when Gov. Américo Villarreal Anaya took office.
Mexico’s investigation focused on financial activity that appeared inconsistent with the businesses’ reported operations. Hacienda said the UIF identified substantial cash movements, domestic and international transfers, purchases of expensive vehicles, jewelry and property, tax inconsistencies, and companies with little identifiable economic activity.
Hacienda described inclusion on the blocked-persons list as a preventive administrative measure without a definitive finding of responsibility. Those listed retain legal avenues to challenge it.
Under OFAC’s guidance on who must comply, U.S. citizens and permanent residents remain subject to sanctions obligations wherever they live.
OFAC’s explanation of blocked property says covered assets are frozen: ownership remains with the blocked party, but transfers, withdrawals and other dealings are restricted. The rule covers property in the United States or in the possession or control of U.S. persons.
Ownership also extends the restrictions beyond the names announced Tuesday. Under OFAC’s 50 percent rule, a business is automatically blocked when one or more blocked parties own at least half of it, directly or indirectly, in aggregate.
For example, if two blocked people each own 25 percent of a supplier, their combined ownership reaches that threshold. An American arranging a renovation from Puerto Vallarta could therefore face payment restrictions involving that supplier even if its name never appeared among the 11 businesses announced this week.
