Introduction

Mexico has not begun a new year with positive expectations for quite some time. Instead, the country faces accumulating challenges that paint a less encouraging picture. A significant issue shaping 2026 is the United States trade relationship, whose future must be resolved in the coming months.

The Uncertain US-Mexico Trade Relationship

In the absence of predictable outcomes, the US-Mexico trade relationship under the T-MEC remains uncertain. The influence of populist regimes has eroded institutional certainty, rendering established pacts and laws less effective against authoritarian wills.

President Donald Trump’s influence, potentially surpassing his own laws, adds to the uncertainty. Moreover, 2026 seems poised to see external tensions and deep internal fractures converge.

Mexico’s Weakening Institutional Framework

As Mexico enters the new year, its institutional architecture is weakened, and its fiscal maneuvering space is dwindling. Governmental missteps are beginning to exact their tolls, with outstanding debts in areas like aviation and the dismantling of autonomous bodies.

These issues, coupled with discriminatory business practices in the energy sector and judicial autonomy annihilation, threaten economic stability. The markets may forgive rhetoric, but not insolvency.

Looming Fiscal and Reform Challenges

Mexico faces substantial fiscal burdens, including an insufficient tax correction to offset irresponsible public spending in 2024. Without a fiscal reform and with low growth rates, the country may confront significant concerns by 2027.

Institutions and pacts offer little resistance against authoritarian intentions. In Washington, T-MEC review will likely be political and transactional rather than technical. Simultaneously, Mexico’s regime dismantles the very checks and balances required by the trade agreement.
