Mexico ended 2025 with a fiscal deficit of 4.3% of gross domestic product (GDP), according to the Finance Ministry’s year-end report. The figure marks a notable improvement from the previous year’s 5.8% shortfall but still surpassed both the original target of 3.9% and a later upward revision to 4.4%.
The reduction in the deficit reflects ongoing efforts to normalize public spending following pandemic-era expansions. However, the failure to meet even the revised target highlights persistent challenges in aligning expenditures with revenues. The Finance Ministry described the decline as one of the largest in recent decades, yet acknowledged that fiscal consolidation remains incomplete.
Public debt continued its upward trajectory. The Historical Balance of Public Sector Borrowing Requirements (SHRFSP), Mexico’s broadest measure of public debt, rose to 52.6% of GDP by year-end, up from 52.0% in 2024 and above the originally forecasted 51.4%. In nominal terms, debt reached MXN 18.6 trillion, representing a real increase of 2.7% over the previous year.

The Finance Ministry maintained that debt levels remain sustainable and compatible with Mexico’s investment-grade credit rating. It emphasized that current debt dynamics allow continued access to favorable financing conditions.
Yet rising debt servicing costs are beginning to weigh more heavily on public finances. The financial cost of debt—including interest payments and associated charges—rose by 9.8% in real terms year-on-year, reaching MXN 1.31 trillion in 2025. This increase reflects higher interest rates and a growing debt stock.
These developments come at a pivotal moment for Mexico’s fiscal policy. The incoming administration of President Claudia Sheinbaum is preparing its first full-year budget under tighter constraints, with limited room for new spending initiatives or tax cuts.
The broader context underscores structural limitations in Mexico’s revenue base, which has long relied on relatively low tax collection compared to peers. Without significant reform or stronger economic growth, maintaining fiscal discipline while meeting social and infrastructure needs may prove increasingly difficult.
While the Finance Ministry has framed the current trajectory as sustainable, analysts caution that continued reliance on favorable external financing conditions leaves Mexico vulnerable to shifts in global markets or domestic shocks.
