Moody's: Government Keeps PEMEX Afloat, Operational Risks Rise

Moody's Ratings has concluded that very strong federal support will maintain PEMEX's B1 credit rating, though government interventions cannot reverse the company's severe operational deterioration. Upstream, PEMEX's production faces an underlying decline rate in the low 20% range at its major oil fields, a crisis exacerbated by a 51% real-term capital investment cut in early 2026 and mixed development contracts that have yet to attract private capital at scale. Downstream, the state's energy sovereignty agenda forces PEMEX to divert crude to inefficient domestic refineries, destroying high-margin export revenues and increasing operational safety risks while high IEPS fuel subsidies prevent the company from capturing global price windfalls.

Moody's Ratings published its report on PEMEX, concluding that strong sovereign support will sustain the national oil company's B1 rating through the current administration but that the underlying operational picture is deteriorating across both upstream and downstream, and that government backing alone cannot counter the structural decline in production or unlock meaningful improvement in refining margins.

The report, authored by Roxana Muñoz, Vice President and Senior Credit Officer, and Marcos Schmidt, Associate Managing Director, frames PEMEX's credit story around a single structural tension: a government that is willing to keep paying for the company, and a company whose operational profile continues to require more support with diminishing returns.

The Government Support Calculus

The federal government backed PEMEX in 2025 with more than US$40 billion in financial interventions, primarily to reduce debt and address supplier obligations. The 2026 federal budget allocates approximately US$14 billion to cover PEMEX's short-term maturities. Banobras stands ready to provide additional funding to support supplier payments, and the recently approved pension reform, which caps high-end benefits across public entities, will partially and gradually lighten PEMEX's pension burden.

Moody's baseline assumption is that PEMEX will spend an average of US$11 billion in capital investment annually over the 2026–2028 period. Debt maturities remain high across that same window, implying that government support will need to continue at a minimum level sufficient to cover refinancing obligations on top of operating needs. The report is direct: PEMEX's ability to meet its financial obligations depends on both government backing and consistent market access and neither is guaranteed to remain available at current terms indefinitely.

Upstream: Decline, Depletion, and the Limits of Mixed Contracts

The upstream section of the Moody's report contains its most sobering findings. PEMEX's liquids production reached approximately 1.65MMb/d in 1Q26, a stabilization, Moody's notes, but one that reflects execution improvements rather than any meaningful change in underlying production trends or reserve dynamics.

The structural constraint is reserve depletion. The main PEMEX producing fields, representing around 80% of upstream output, are declining at significant annual rates. On a production-weighted basis, those declines imply an underlying decline rate in the low 20% range. Individual field data is stark: annual production is declining at double-digit rates at Maloob and Zaap, and even more steeply at Quesqui and Tupilco Profundo. This means PEMEX must reinvest substantially just to hold production flat and its capital budget is being cut, not expanded.

Capital investment contracted approximately 51% in real terms in early 2026 compared to the prior year, reflecting Mexico's tighter fiscal conditions. Moody's warns that this dynamic will weigh further on both operational performance and production sustainability well past 2027.

On mixed development contracts, the Sheinbaum administration's mechanism for bringing private capital into upstream operations, Moody's is measured. To date, PEMEX has awarded approximately 10 contracts, most of which are signed and progressing toward execution, with projected incremental production of approximately 76Mb/d in 2026 with a moderate increase thereafter. But the agency flags a structural limitation: the current contract structure has not yet attracted enough private investment to alter PEMEX's production trajectory materially, particularly for the large, capital-intensive projects where the depletion problem is most acute. Execution and scalability remain uncertain.

Downstream: The Refining Trap

The refining narrative in the report is equally constrained, and for a reason that is distinct from underinvestment: policy design. PEMEX's declining crude export volumes reduce its exposure to higher-margin international markets as an increasing share of domestic production is directed toward domestic refining. That policy choice, driven by the energy sovereignty agenda, structurally weakens PEMEX's revenue profile at a moment when international oil prices are elevated.

The Iran war-driven oil price surge, which pushed Brent above US$100/b in March 2026 and has kept Mexico's export blend at elevated levels through May, is generating less benefit for PEMEX than the headline price suggests. Government domestic fuel pricing, implemented through reductions in the IEPS excise tax, implies subsidies of approximately MXN4.6/L for diesel and MXN3.3/L for gasoline, effectively preventing PEMEX from capturing the margin that higher international prices would otherwise deliver.

Moody's adds a safety dimension that is rarely framed in credit terms: capital spending reductions raise risks about the reliability and efficiency of PEMEX's downstream operations over time, with higher incidence of explosions. The Gulf of Mexico spill documented earlier this year and the recurring safety incidents at the Olmeca refinery in Dos Bocas are consistent with that assessment.

Market Access: Local Refinancing, International Uncertainty

On financing, the report confirms that PEMEX successfully accessed the local market in 2026 and will likely return in the second half of the year for an amount broadly in line with its approximately US$1.7 billion in recent issuance, primarily to support liquidity, not capital investment.

The timing of a potential return to international markets remains uncertain. If PEMEX does access external markets, it would use proceeds to refinance outstanding obligations rather than fund new investment, with any liability management strategy likely extending to more distant maturities to smooth the amortization schedule and reduce refinancing risk.

The practical implication is direct: PEMEX's debt market activity in 2026 and 2027 is a financial maintenance operation, not a capital formation strategy. Investment growth, the prerequisite for production stabilization, will have to come from government budget allocations and from the private capital that mixed contracts are designed to attract, but have not yet delivered at the required scale.
