Pemex Supplier Crisis Deepens as Jailed Admiral Writes Again

Mexican Vice-Admiral Manuel Roberto Farías Laguna sent his fifth letter from El Altiplano maximum-security prison to President Claudia Sheinbaum on Monday May 11, 2026, citing the president’s own defence of Sinaloa governor Rubén Rocha Moya to demand evidentiary scrutiny in his huachicol fiscal case 325/2025. The letter lands as Pemex supplier debt sits above 500 billion pesos (US$28 billion), with the Tabasco contractor network reporting roughly 22,000 jobs lost over 15 months and 1,200 contractors near insolvency. The two files intersect inside the broader fuel-smuggling network detailed in Monday’s Cártel del Noreste capture in Nuevo León.

The Rio Times, the Latin American financial news outlet, reports that Farías Laguna has been held at El Altiplano since September 2, 2025 on organised-crime and huachicol fiscal charges. In his fifth letter, the vice-admiral argued that the prosecution failed to produce evidence with the “circumstances of time, mode and place” required by Mexican criminal procedure, and that he was victim of a “corrupting effect” caused by a press conference one day before his vinculación a proceso hearing.

The letter’s rhetorical move is the citation of Sheinbaum’s own May 11 morning press conference, in which the president had publicly demanded “convincing evidence” from US authorities for Mexican action against Rocha Moya. Farías Laguna asks the same standard of evidence be applied to his own case. He says he has been denied access to investigation file FED/FEMDO/FEIDRPIFAME-CDMX/0000568/2024, and remains in a “complete state of indefension.” The presidency has not formally responded to any of the five letters.

The Brother in Buenos Aires

Counter-Admiral Fernando Farías Laguna, the vice-admiral’s brother and nephew of former Marine Secretary José Rafael Ojeda Durán, was detained in Buenos Aires on April 23, 2026 in the Palermo neighbourhood. Argentine authorities reported he had entered the country from Colombia using a forged Guatemalan passport under the alias Luis Lemus Ramos, with a falsified DPI identification document.

The Argentine Servicio Penitenciario Federal classified Fernando Farías Laguna as a presumed member of a criminal organisation called “Los Primos,” dedicated to hydrocarbons trafficking. He has rejected extradition to Mexico and announced he will request political asylum in Argentina. Mexican investigators previously identified deposits, insurance policies and high-value purchases in his name that they consider inconsistent with declared income.

The two-brother case is the most visible institutional thread inside the huachicol fiscal investigation, which the Mexican government calls the largest fiscal fraud in the country’s history at approximately 600 billion pesos. The May 11 capture of Cártel del Noreste cell leader José Antonio Cortes Huerta in Nuevo León is the latest extension of the same case file.

The Pemex Supplier Math

The supplier crisis has hollowed out Tabasco, the state often nicknamed “the Mexican Dubai” during the López Obrador administration. Tabasco’s GDP depends approximately 70% on hydrocarbon activity, and Campeche’s roughly 90%. Industrial parks along the Villahermosa-Cárdenas and Villahermosa-Paraíso corridors host empty warehouses, idle drilling rigs and unpaid Baker Hughes and Halliburton equipment now reduced to single-floor offices from full towers.

The Auditoría Superior de la Federación documented payment delays of up to 454 days on the Olmeca refinery in Dos Bocas, with 122 of 125 audited contracts (worth 28.81 billion pesos combined) running behind authorised CFDI electronic-payment instructions. Grupo México and other large contractors have publicly disclosed write-downs, including a 72.3% drop in Q4 2025 Perforadora Pemsa sales and a 94.4% decline in EBITDA from the suspension of four Jack-Up platforms tied to Pemex non-payment.

The Coparmex and Canacintra Pressure

Coparmex, the principal Mexican private-sector employer confederation, has formally warned that the Pemex supplier-debt situation threatens enterprise stability and social cohesion across hydrocarbon-dependent states. Canacintra Tabasco president Alejandro Frías Díaz confirmed in February that Pemex had begun receiving 2025 estimates and invoices for payment, but the 2024 backlog remains unresolved and the situation is now being described as the most acute supplier crisis in the company’s recent history.

Sheinbaum has acknowledged the supplier issue publicly and promised in late June that normalisation would begin in July. Frías Díaz said in March that 2025 invoices were beginning to flow but 2024 payments remained largely outstanding. The political dimension intersects with the senator Adán Augusto López file, with the Torre Empresarial in Villahermosa, owned by a López-linked company, sitting alongside the increasingly empty Torre Usuma that the company has reportedly rented from Pemex.

• FGR formal response to the Farías Laguna letter cycle: whether prosecutors release the investigation file FED/FEMDO/FEIDRPIFAME-CDMX/0000568/2024 to the defence.
• Tabasco unemployment data: monthly IMSS prints through Q2 2026 against the 1,500-jobs-per-month baseline.
• Senator Adán Augusto López file: whether the Torre Empresarial and Torre Usuma threads enter the formal investigation.
