Mexico’s sovereign debt is getting the kind of treatment usually reserved for countries with far worse credit scores. Bond traders are now pricing Mexican government paper as if it were junk, a direct consequence of the roughly $130 billion the government has funneled into keeping Petroleos Mexicanos, the state-owned oil behemoth, from collapsing under its own weight.
On May 21, Moody’s made it official by downgrading Mexico one notch to Baa3, the lowest rung of investment-grade territory. One more slip and the country falls into speculative grade, a classification that would trigger forced selling by institutional investors whose mandates prohibit holding junk-rated debt.
The numbers behind the bailout
Government support for Pemex in 2025 alone clocked in at approximately $35 billion, equivalent to 1.9% of GDP.
Funding that kind of commitment required Mexico to hit the bond market hard. The country raised over $41 billion in hard-currency sovereign bonds during 2025, making it the largest emerging market borrower that year. Most of that capital went straight toward managing Pemex’s debt load and keeping the company liquid.
The strategy produced a paradoxical short-term result. Pemex’s dollar bonds delivered average returns of about 24% in 2025, the best performance of any issuer in Latin America according to Bloomberg data.
Fitch, for its part, maintains Mexico at BBB- with a one-notch penalty explicitly linked to Pemex’s estimated $99 billion in financial obligations. That means both major rating agencies now have Mexico sitting one downgrade away from junk status.
Sheinbaum’s balancing act
President Claudia Sheinbaum’s administration has shown no signs of cutting the cord. The 2026 budget earmarks around $13-14 billion to meet Pemex’s obligations, and Sheinbaum has publicly stated that 95% of the company’s prior supplier debts have been settled.
Rating agencies are watching closely. Moody’s cited Pemex’s contingent liabilities as a central factor in the downgrade, signaling that the agency views the oil company’s problems as inseparable from Mexico’s sovereign risk profile.
What traders are actually pricing in
The gap between Mexico’s official investment-grade rating and how its bonds actually trade in the market tells a revealing story. Credit default swap spreads and bond yields have widened to levels more consistent with BB-rated issuers, meaning the market has effectively pre-empted the rating agencies by treating Mexican debt as speculative.
For foreign institutional investors, this creates an uncomfortable position. Many pension funds and insurance companies are required to hold only investment-grade debt. If either Moody’s or Fitch downgrades Mexico one more notch, those investors would be forced to sell, potentially triggering a cascade of outflows that would pressure the peso and push borrowing costs higher.
