USMCA Review Reignites Debate Over Arbitration and Investment Certainty in Mexico
The debate over investor protections is back at center stage, driven by energy policy and the need for clear rules in long-term sectors.
Mexico is heading into the next review of the United States–Mexico–Canada Agreement (USMCA) with a conversation that blends trade, energy, and the economic rule of law: the real scope of protections for foreign investors and the mechanisms for resolving disputes when the rules change. For decades, the country sold international capital on the idea of a baseline level of certainty—especially important for capital-intensive projects. Under the USMCA, however, investor–state dispute settlement (ISDS) was scaled back and made conditional, opening a debate that is now returning in a big way.
Under NAFTA’s original architecture, ISDS allowed foreign companies to seek international arbitration if they believed government decisions harmed their investment. With the USMCA, the playing field changed: the mechanism was eliminated entirely between the United States and Canada, and retained for Mexico only in a limited form. In most cases, before escalating to international arbitration, investors must first pursue claims in Mexican courts for an extended period, while broader access was reserved for sectors defined as strategic, including oil, gas, power generation, telecommunications, infrastructure, and transportation.
The issue’s return to the agenda is no accident. In the United States, ISDS has divided opinion for years: for some, it is a legal safety net that makes investing easier in places with regulatory risk; for others, it creates a legal “fast lane” for foreign corporations and can pressure governments to soften public policy out of fear of costly litigation. That clash of views—already present during NAFTA’s renegotiation—is resurfacing as the agreement’s formal review approaches.
On the Mexican side, the debate is especially sensitive because it intersects with the need to attract investment amid the reshuffling of North American supply chains. “Nearshoring” has increased interest in Mexico as a manufacturing platform, but it has also put a spotlight on the factors that determine whether new plants are viable: electricity availability, permitting, logistics infrastructure, security, water, and regulatory stability. In that context, any adjustment to investment-protection mechanisms has implications that go far beyond the text on paper: it can influence financing costs, appetite for long-horizon projects, and perceptions of country risk.
In U.S. legislative analysis, Mexican energy policy is cited as one of the areas most likely to generate friction during the USMCA review. That is partly explained by the sector’s weight: globally, a significant share of investment arbitrations is concentrated in energy and extractive industries, where committed sums are typically large and returns are planned over decades. For companies with generation or fuels projects, certainty around rules, access to networks, and nondiscriminatory treatment becomes central.
Energy, Investment, and the Certainty Temperature Check
The discussion is intensifying due to regulatory and public-policy changes in Mexico aimed at strengthening the role of state-owned enterprises, particularly the Federal Electricity Commission (CFE). The debate over the respective roles of the public and private sectors in the power system—as well as operational priority and market-access conditions—has been flagged by U.S. officials and lawmakers as a potential source of trade disputes. Beyond the bilateral disagreement, investors view the issue as a gauge of regulatory stability: when rules are perceived as shifting, uncertainty about future cash flows rises, and risk premiums increase for project financing or expansion plans are reshaped.
Tensions have already taken formal channels between governments. In recent years, the United States triggered USMCA consultations, arguing that certain Mexican measures could run counter to commitments on investment, market access, and the treatment of state-owned enterprises. That track record makes it more likely that the treaty review will seek additional commitments, technical clarifications, or adjustments that reduce gray areas. For Mexico, the challenge is twofold: defending its policy space while also avoiding signals that translate into lower investment in the sectors the country needs to grow—such as energy, infrastructure, and advanced manufacturing.
The investor-protection chapter also touches a structural issue: the Mexican judicial system’s ability to resolve disputes within reasonable timeframes and with predictable standards. The requirement to litigate first in domestic courts—before gaining access to international arbitration in many scenarios—raises the importance of expedited procedures and a consistent regulatory framework. In practice, certainty depends not only on the treaty text, but on how permits, regulations, and rulings are applied, and on whether clear administrative mechanisms exist to resolve differences without freezing investments.
Looking ahead, the outcome of the debate will depend on political and economic balances across all three countries: in the United States, pressure from industries with significant investments in Mexico; in Canada, efforts to protect its companies with a regional footprint; and in Mexico, the priority of securing growth through productive investment without giving up energy-policy goals. With global interest rates still a sensitive factor and countries competing to attract capital, the review’s outcome could influence industrial location decisions—especially in states receiving new plants and in logistics corridors tied to exports.
In short, the USMCA review reopens a central question for the business climate: how robust and accessible the avenues for resolving investment disputes will be, and what signals Mexico will send about regulatory stability in strategic sectors such as energy. The answer could shape both the pace and quality of investment that accompanies North America’s production realignment.
