The USMCA joint review that took place on 1 July 2026 was supposed to be a confrontation. For months, the prospect of the United States using the agreement’s mandatory six-year check-in to bludgeon Canada and Mexico (or threaten outright withdrawal) had dominated trade policy conversations in Washington. Instead, the meeting was virtual, brief, and quiet.
The reason, in large part, is Iran. The conflict has absorbed the White House’s attention so completely that the political oxygen required to turn a trade review into a diplomatic crisis simply was not available. Washington needed its two largest trading partners onside, not on the defensive.
What the USMCA Joint Review Actually Decided
Under Article 34.7 of the USMCA’s Final Provisions, the 1 July meeting was the first opportunity for all three parties to confirm whether they wished to extend the agreement for a further 16-year period, which would run through to 2036. The United States declined to do so. The agreement remains in force, but the decision starts a 10-year clock: if no extension is agreed before that period expires, the USMCA lapses entirely.
That is a meaningful outcome, even if it arrived without fanfare. The practical consequence is annual joint reviews for the remainder of the term, rather than a clean extension. Steady diplomacy has replaced the brinkmanship many anticipated.
The groundwork for a calmer process had been laid months earlier. In April 2026, US Trade Representative Jamieson Greer met with Mexican President Claudia Sheinbaum in Mexico City and, alongside Mexican Secretary of Economy Marcelo Ebrard, agreed to open formal bilateral negotiations for the review in the week of 25 May. A second bilateral round followed on 15-17 June 2026 in Washington. A third round was scheduled for the week of 20 July. The machinery of negotiation, however unglamorous, was turning.
The Stakeholder Picture Is More Complicated Than the Calm Suggests
It would be a mistake to read the subdued tone as consensus. When Ambassador Greer reported to Congress in December 2025, ahead of a three-day public hearing held on 3-5 December, the picture that emerged was one of qualified support. Stakeholders broadly backed the USMCA, but virtually all of them called for improvements. Some made their support for extension conditional on those improvements being delivered.
The two issues that came up most consistently were rules of origin, specifically, whether preferential tariff treatment was actually flowing to US and partner producers rather than being gamed by non-member supply chains, and the distorting effects of industrial overcapacity in non-market economies. According to EY Tax News, which summarised Greer’s Congressional briefing, those two themes shaped the administration’s entire framing of what the review needed to achieve.
That framing matters because it explains why Greer’s team has not pressed for a rapid extension. The tariff actions taken against Canada and Mexico earlier in the Trump administration are, in Greer’s view, already reshaping North America’s economic relationships. If those changes have altered the baseline, the argument runs, then a confrontational review is unnecessary: the leverage has already been applied.
Whether that logic holds is worth scrutinising. US goods and services exports to Canada and Mexico stood at $617 billion in 2020, according to USTR data cited in Greer’s Congressional report. The trade relationship is too large, and too tightly integrated, to reshape by tariff pressure alone. The auto sector, in particular, relies on cross-border supply chains that cannot be rerouted quickly or cheaply. If the review process eventually produces demands that the auto industry cannot absorb, Washington will have traded a short-term diplomatic calm for a longer-term industrial headache.
Arturo Sarukhan, Mexico’s former ambassador to the United States, framed the geopolitical logic bluntly. Any move to destabilise North America’s economic framework at a moment when Washington is trying to build a coalition against China would be, in World Cup terms, ‘a huge own goal’. That argument appears, for now, to be carrying weight inside the administration.
The real test comes not in July 2026 but in the rounds that follow. If the bilateral talks with Mexico surface irreconcilable demands on rules of origin, or if Canada’s position hardens ahead of the next review cycle, the quiet that descended on 1 July will start to look less like a resolution and more like a postponement. The 10-year countdown has begun.
