Fitch Ratings has issued a stark warning on the future of the US-Mexico-Canada Agreement (T-MEC), cautioning that the trade pact could lapse into a ‘zombie mode’—remaining legally in force but increasingly vulnerable to annual renegotiations and discretionary tariff measures, particularly from the United States. The assessment forms part of Fitch’s 2026 outlook for Mexico, which highlights mounting institutional and policy risks that could undermine one of the country’s most critical economic frameworks.
The agency’s concerns extend beyond trade mechanics. It sees Mexico’s broader regulatory environment as increasingly unpredictable, with recent domestic reforms—particularly in the judiciary and labor sectors—raising questions about legal certainty and investor protections. These developments, Fitch suggests, may deter foreign capital at a time when Mexico is seeking to position itself as a prime destination for nearshoring investment within North America’s integrated supply chains.
Despite its geographic advantages and preferential access to the US market under T-MEC, Mexico faces structural headwinds. Fitch projects GDP growth of just 1.3% in 2026, placing it among the weakest performers in Latin America. The agency attributes this sluggish outlook to a combination of weak domestic demand, declining oil production, and a widening fiscal deficit. Although fiscal consolidation efforts began in early 2023, Fitch notes that limited revenue growth constrains their sustainability.
T-MEC risks becoming a ‘zombie agreement’—legally intact but politically fragile and economically uncertain.
The fiscal picture is further complicated by recent tax policy changes. Reforms to value-added tax (VAT) rules have increased operational costs for businesses, contributing to Fitch’s decision to downgrade its outlook for Mexico’s banking and insurance sectors. The agency cites policy uncertainty as a key factor behind this deterioration, suggesting that financial institutions may face growing challenges in navigating an unstable regulatory landscape.
T-MEC’s potential weakening carries significant implications. The agreement has served as a cornerstone of Mexico’s export-led growth model since its inception. If its institutional framework becomes subject to political discretion or annual renewal processes, predictability for investors and exporters could erode. This would not only affect trade flows but also diminish Mexico’s attractiveness as a manufacturing hub within North America.
Nonetheless, some mitigating factors remain. T-MEC continues to provide a legal framework for trilateral trade, and Mexico has shown initial steps toward fiscal discipline. Moreover, despite regulatory concerns, some nearshoring activity persists, driven by structural advantages such as proximity to the US market and existing industrial infrastructure.
Still, Fitch’s analysis underscores the importance of institutional clarity and macroeconomic stability in preserving Mexico’s competitiveness. Without credible commitments to regulatory transparency and fiscal responsibility, the country risks undermining its role in regional supply chains at a time when global firms are reassessing their production footprints.
As 2026 unfolds, much will depend on whether Mexican authorities can reinforce investor confidence through consistent policy implementation and institutional safeguards. In the absence of such measures, the specter of a ‘zombie’ T-MEC may become more than just a metaphor.
