The Center for Economic Studies of the Private Sector (CEESP) warned that unfulfilled fiscal consolidation poses a major threat to Mexico’s public finances heading into 2027, driven by weak revenue growth and high spending rigidity. Mandatory pension outlays, financial support for PEMEX, and expanding debt servicing costs continue to strain federal balance sheets as GDP growth decelerates. Addressing these structural imbalances requires realistic macroeconomic modeling in the upcoming 2027 Economic Package to safeguard sovereign stability across commercial, financial, and industrial sectors.

Mexico’s public deficit surged 36% year-over-year to MX$559 billion (US$32.87 billion) during 1H26, as total public revenues fell MX$141 billion (US$8.29 billion) short of approved budget targets. According to an analysis by the Center for Economic Studies of the Private Sector (CEESP), this widening fiscal gap underscores a growing structural imbalance where total public expenditure expanded by 2.1% in real terms, while total public revenue grew by just 0.1% and tax collection rose 0.4%.
CEESP warned that failing to execute committed fiscal consolidation represents one of the primary risks facing Mexico’s public finances heading into 2027. “One concern is that the committed consolidation for public finances will not be fulfilled,” CEESP stated, noting that unaddressed fiscal imbalances will generate greater vulnerability in subsequent years. The organization emphasized that the upcoming 2027 Economic Package must incorporate a realistic macroeconomic framework that acknowledges tax revenue shortfalls and spending rigidities.
Precautionary reserves to buffer these revenue shortfalls remain severely constrained. The Budget Revenue Stabilization Fund (FEIP) and the Stabilization Fund for the Revenue of Federated Entities (FEIEF) hold approximately MX$150 billion (US$8.82 billion) combined, an amount barely sufficient to cover the MX$141 billion (US$8.29 billion) deficit registered against approved budget programming during the first six months of the year.
Escalating Public Debt
Rising debt servicing costs and energy sector support continue to strain federal balance sheets. The Historical Balance of Public Sector Financial Requirements reached MX$19 trillion (US$1.12 trillion) in 2Q26, marking an increase of MX$1.3 trillion (US$76.45 billion) compared to the same period a year earlier. Total public debt is projected to reach MX$20.4 trillion (US$1.2 trillion) by the end of the current year and expand to MX$21.8 trillion (US$1.28 trillion) by 2027, unless official budget proposals present lower figures. CEESP added that financial servicing costs could rise to represent 4.1% of gross domestic product (GDP), exceeding the originally estimated deficit target of 3.5% of GDP.
The financial condition of PEMEX adds substantial operational burden to sovereign accounts. Federal equity injections to the state oil company reached MX$100.4 billion (US$5.9 billion) during the 1H26, marking a 6.2% increase compared to the same period in 2025. Credit rating agency Moody’s estimates PEMEX’s baseline funding needs at an average of US$14.9 billion annually over the 2026-2028 period to cover debt maturities, supplier obligations, and capital expenditures.
Budgetary execution is further restricted by mandatory social commitments and cash transfer mechanisms. Pension and retirement outlays were assigned MX$1.7 trillion pesos (US$99.97 billion) this year, absorbing nearly one-fourth of total programmable spending. Concurrently, priority social programs absorb 42% of total federal government revenue and 45% of tax collection. Although the Ministry of Finance and Public Credit (SHCP) outlined a 3.2% reduction in public spending for 2027 in its April 2026 Preliminary General Economic Policy Guidelines to achieve fiscal consolidation, CEESP cautioned that expenditure rigidity could hinder larger adjustments.
Economic Growth Constraints
These domestic fiscal challenges align with broader sovereign rating evaluations. In an Aug. 2026 report, Moody’s Ratings indicated that Mexico requires a fiscal adjustment equivalent to 2.4% of GDP to stabilize its public debt, which is on track to approach 55% of GDP by 2028 due to rigid social transfers, high borrowing costs, and energy sector support. Moody’s highlighted that debt service costs have escalated sharply, with interest payments now absorbing approximately 17% of government revenues, up from 10% to 11% in 2021.
CEESP noted that latest economic growth forecasts of around 1.1% for this year will continue to dampen tax collection. The organization recommended that financial authorities adjust the macroeconomic framework to a lower-growth environment, prioritizing economic stability, public investment, security, education, and healthcare without threatening the long-term sustainability of public finances.
