In early October 2026, Mexico’s Secretary of Finance, Édgar Amador Zamora, testified before the Senate that the Financial Intelligence Unit (UIF) was not conducting investigations into Andrés Manuel López Beltrán or his business associates. This testimony followed concerns raised by Senator Mayuli Martínez Simón regarding alleged networks involving influence peddling, fuel smuggling, and public contracts worth approximately 49 billion pesos. By late October, the UIF took direct action by freezing the bank accounts of businessman Gerardo Sánchez Zumaya, a former political aspirant for the Morena and PT coalition. The freeze led to legal injunctions from entities such as Grupo Mineral & Logistic, a company that received contracts from Pemex. The investigation into Sánchez Zumaya involves allegations of a fraudulent invoicing network, with reports indicating that Pemex and the Mexican Petroleum Institute paid over 2.8 billion pesos to companies linked to him. ## Timeline ### 2026-10-23: Mexico's UIF freezes accounts of businessman Gerardo Sánchez Zumaya Mexico's UIF froze the accounts of businessman and political aspirant Gerardo Sánchez Zumaya amid allegations of a fraudulent invoicing network involving Pemex contracts and political ties. 4 sources. https://clstr.news/cluster/mexicos-uif-freezes-accounts-of-businessman-gerardo-snchez-zumaya ### 2026-10-07: Mexico Finance Secretary denies UIF investigations into López Beltrán Mexico's Finance Secretary stated the UIF is not investigating Andrés Manuel López Beltrán or his associates despite opposition allegations of corruption and illicit business networks. 2 sources. https://clstr.news/cluster/mexico-finance-secretary-denies-uif-investigations-into-lpez-beltrn --- Cite as: Mexico Financial Intelligence Unit investigations.
