Mexico’s gross domestic product grew 1.4% in the second quarter of 2026, rebounding from a 0.3% contraction in the first quarter and outperforming USMCA partners. However, escalating public debt service obligations — projected by SHCP to reach a 37-year high of 4% of GDP in 2027 — are squeezing fiscal space and infrastructure investment. This structural imbalance affects sovereign risk ratings, infrastructure developers, and foreign investors navigating Mexico’s macroeconomic environment.

Mexico’s economy expanded 1.4% in 2Q26, rebounding from a 0.3% contraction in the first quarter, according to OECD data. The performance placed Mexico second among G20 economies, trailing only India, which advanced 1.8%. However, this economic recovery is increasingly colliding with mounting public debt obligations, as projected interest payments on national sovereign debt threaten to absorb a record share of gross domestic product (GDP) and constrain fiscal maneuverability.
Highlighting the figures during her morning press conference, President Claudia Sheinbaum noted that performance could improve in the second half of the year. The OECD report published on Sept. 14 underscored that Mexico experienced a sharp rebound. Within North America, Mexico led USMCA partners, outpacing Canada at 0.8% and the United States at 0.4%. Overall, the G20 aggregate economy advanced 0.7% in the second quarter, while the OECD area registered growth of 0.5%. On a year-on-year basis, G20 GDP expanded 3.1% in 2Q26.
The quarterly expansion follows a volatile trajectory across recent periods. Mexico recorded GDP contractions of 0.02% in 2Q25 and 0.10% in 3Q25, before growing 0.95% in 4Q25 and contracting 0.3% in 1Q26. The 1.4% gain between April and June reversed the previous drop, marking Mexico’s strongest quarterly growth within the OECD framework. Across major peers, 2Q26 growth included Indonesia at 1.3%, Turkey at 1.1%, and China at 0.9%.
Escalating Debt Service Pressures Sovereign Fiscal Space
Despite quarterly momentum, public finance data from the Ministry of Finance and Public Credit (SHCP) indicates that the financial cost of servicing Mexico’s public debt will reach 4.0% of GDP in 2027. This interest burden represents the highest level recorded since 1990, when interest payments reached 7% of GDP. SHCP attributes the increase to projections showing total public debt reaching 55% of GDP in 2027.
The year 2027 will mark the fourth consecutive year of expanding public debt relative to economic output, following an upward trend that raised total debt to 54.0% of GDP by late 2026. Fitch Ratings projects total public debt could reach 58% of GDP by the end of 2026.
Credit rating agencies and financial institutions have raised concerns regarding the velocity of debt accumulation and the resulting contraction in fiscal flexibility. While Mexico’s overall debt-to-GDP ratio remains lower than that of peer nations like Brazil, Colombia, and the United States, analysts emphasize that market dynamics differ for emerging market debt.
“The issue concerning rating agencies is not just the percentage of GDP, which is already high, but the upward trend,” stated Federico De Noriega Olea, corporate and finance partner at Hogan Lovells Cadwalader. “There are other economies more indebted than Mexico, but demand for United States debt is much more stable and growing than demand for the debt of emerging economies.”
Debt Servicing Outpaces Infrastructure Investment
With obligatory government expenditures rising alongside lower tax and oil revenues that were previously covered by debt, elevated interest rates have pushed 2027 debt service costs to historic highs. At an estimated MX$1.6 trillion (US$92.46 billion), the financial cost of servicing public debt in 2027 will exceed net revenue expected from new government borrowing in that year. The MX$1.6 trillion interest allocation equals more than nine times the 2027 projected budget for the Ministry of Infrastructure, Communications and Transportation (SICT), double the total allocation for PEMEX and stands just MX$197 billion (US$11.39 billion) below total expected Value Added Tax (IVA) collections.
De Noriega Olea noted that the 4% of GDP projected for debt servicing in 2027 significantly surpasses the 2.6% of GDP allocated to public infrastructure investment. “Investment spending translates, in the medium and long term, into growth for the Mexican economy,” De Noriega Olea highlighted. “By having better infrastructure, companies invest more and sell more products, which in turn causes them to pay more taxes. This generates a virtuous cycle that allows the government to obtain more resources to allocate toward improving infrastructure or reducing debt levels. Allocating resources directly to pay interest on debt does not generate this positive cycle.”
“Debt is one of the main reasons preventing fiscal consolidation,” warned Judith Senyacen Méndez Méndez, Executive Director of the Center for Research in Economics and Budget (CIEP). “It is important to track its growth because it is growing faster than the revenue adjustments being made.”
Long-Term Fiscal Sustainability Concerns
The squeeze on fiscal space limits government capacity to deliver essential public services, including health, education, and security. “An uncontrolled increase in financial costs limits the government’s ability to fulfill its commitments and, in an extreme scenario, increases the risk of compromising fiscal sustainability,” explained Jorge Cano, Public Expenditure Program Coordinator at México Evalúa.
Projections regarding debt trajectory diverge between official estimates and independent analysts. SHCP forecasts that after reaching peak levels in 2027, the financial cost of debt will stabilize at 3.7% of GDP between 2028 and 2030, with total debt balances holding at 56.4% of GDP.
Conversely, calculations by México Evalúa project that the historical debt balance will reach 61% of GDP by 2030, driving annual interest payments to 4.4% of economic output. Per the research organization, unless fiscal revenue mechanisms are strengthened or spending is reallocated toward productive capital assets, rising debt service costs will continue to constrain Mexico’s macroeconomic resilience.
