PEMEX debt burden impacts Mexico's sovereign credit profile

The Mexican government has provided approximately 1.71 trillion pesos (over $130 billion USD) in direct capital injections to support Petróleos Mexicanos (PEMEX) between 2018 and 2026. While these transfers have helped reduce PEMEX's short-term debt by 57 percent and its debt to suppliers by 16 percent, the fiscal burden is impacting Mexico's national credit profile.

Credit rating agencies have noted that PEMEX's debt effectively lowers Mexico's sovereign rating by one notch. Moody’s downgraded the country to Baa3 in May 2026, citing fiscal weakening, while Fitch warns that the company's debt load remains a significant drag on the sovereign. Consequently, although Mexico technically maintains investment grade, market spreads and risk premiums are increasingly reflecting speculative-grade levels, raising borrowing costs for the government and private sectors.

Despite the massive fiscal support, the financial cost of PEMEX's debt reached 78 billion pesos, representing 62 percent of its operating income. While net income grew by 7.7 percent, the ratio of financial debt to total liabilities and equity remains in a critical range of 62.5 percent.
