Western Hemisphere: USMCA Forward 2026 review puts trade rules, agriculture, and supply chains on the line
western hemisphere trade is entering a high-stakes moment as the United States-Mexico-Canada Agreement goes through its first-ever joint review this year. The U. S., Canada, and Mexico must decide by the end of the process whether to renew, revise, or terminate the deal—an outcome that could reshape regional manufacturing and farm trade. As of 11: 00 AM ET on March 5, 2026, the review is being framed by competing pressures: recurring uncertainty built into the agreement’s structure and rising calls to clarify what is working and what needs to change.
Western Hemisphere review decision: renew, revise, or terminate
The current review is the first joint review of the USMCA, and it ends with a choice that cannot be avoided: the three partners must renew, revise, or terminate the agreement. A separate guide to the Canada-United States-Mexico Agreement review—often referenced using the acronym CUSMA—underscores how the process could set the tone for the future of Canadian agri-food trade and the broader tariff environment between Canada and the United States.
One central tension is durability. An assessment of the agreement notes that USMCA modernized North American trade governance but replaced NAFTA’s durability with a conditional structure that introduced recurring uncertainty. That uncertainty now sits at the center of the 2026 decisionmaking window.
What the agriculture sector is watching right now
For agriculture, the review is being treated as a potential reset point. North American agriculture’s integration under NAFTA and now USMCA has created a continental market that buffers producers and consumers from global shocks, supporting affordable food, stable value chains, and continued competitiveness. The same analysis highlights that the review should prioritize steps that keep the sector competitive and resilient.
In the CUSMA-focused guide, the agreement is described as allowing producers in all three countries to trade with each other in a mostly tariff-free environment. It also flags a specific risk pathway: a sustained disruption of traffic through Hormuz would not only constitute an energy crisis, but could also trigger a fertilizer shock—prices rising dramatically and supply falling—creating a direct risk to global food security.
In the middle of the current debate, western hemisphere farm groups and policymakers are weighing whether the structure of the agreement can deliver predictable market access while protecting value chains from sudden external shocks.
Immediate reactions from officials and experts
Political signals are sharpening the sense of uncertainty heading into the review. U. S. President Donald Trump has consistently expressed displeasure with CUSMA despite the fact that it was negotiated during his first administration. In Canada, Prime Minister Mark Carney has said the relationship Canada thought it had with the United States is over, signaling what he described as a possible new era in North American trade.
Patrick Leblond, Professor at the University of Ottawa’s Graduate School of Public and International Affairs, said it is unlikely the three countries will return to the original mode of tariff-free trade under CUSMA. “It sounds like the Americans are not in a compromising mood, ” Leblond said. “It sounds like, ‘Okay, we’re going to put the gun to your head, and you’re going to give us what we want. ’”
Leblond also emphasized that there is nothing forcing the parties to start negotiating on July 1, described as the official start of the review. On withdrawal mechanics, he said any party may leave the agreement with six months’ notice, but argued the United States could still take more drastic action in practice. “The reality is, … the U. S. can just pull out and say, ‘yeah, as of tomorrow, we are not applying (CUSMA) anymore, ’” Leblond said. He added that if Canada and Mexico sued, arbitrators would likely find the U. S. at fault and allow retaliation with tariffs, leaving Canada and Mexico to decide how to react.
Michael Harvey, Executive Director of the Canadian Agri-Food Trade Alliance (CAFTA), said it’s unlikely Trump will pull out of the agreement completely.
Quick context: why this review matters now
Analysts writing for a 2026 USMCA Forward report describe the moment as “a time of flux, ” with developments over the past year making USMCA more central to trade and manufacturing for all three economies and raising the stakes for the review. The report’s contributors also point to major shifts in integrated sectors like autos and steel, alongside vulnerabilities in regional pharmaceutical supply chains.
What’s next
The next phase is the hard part: moving from broad warnings and sector priorities into a choice to renew, revise, or terminate—without letting uncertainty itself become the defining feature of North American commerce. As of 11: 00 AM ET on March 5, 2026, officials, industry leaders, and researchers are pressing for clearer terms on competitiveness, reliability, and resilience across agriculture and manufacturing. For the western hemisphere, the review’s endgame will be measured in whether trade rules feel predictable enough for producers and investors—and whether the agreement can avoid a new cycle of tariff threats and retaliation.
