The United States, Canada, and Mexico have formally launched a review of the United States-Mexico-Canada Agreement, the trilateral trade deal that replaced NAFTA when it took effect on July 1, 2020. The review is mandatory under the agreement’s own terms, triggered by a built-in six-year checkpoint set for July 1, 2026.
Trump has made his position clear: he is not looking to renew the USMCA without significant concessions from both neighbors.
What Trump actually wants
The administration’s demands are specific. The US wants expanded access to Canada’s dairy market, changes to how alcohol trade is regulated, tougher enforcement of labor provisions, revised automotive rules of origin, and steps to narrow trade deficits with Mexico.
The backdrop makes this harder. Tariff disputes between the US and its two neighbors are already ongoing, and the research shows that negotiations are proceeding primarily on a bilateral basis rather than as a unified three-way conversation.
How the sunset clause actually works
The USMCA contains a sunset clause. If the parties do not agree to extend the deal at the 2026 review, the agreement enters a series of annual reviews, without a long-term extension, until 2036, at which point the agreement would expire entirely if no consensus is reached.
Canada and Mexico are pushing for a straightforward 16-year extension, which would lock in the agreement through 2042. The US has not signaled it is prepared to accept that on current terms.
The nearly $2 trillion in annual trade flowing across North American borders under this framework covers everything from agriculture and energy to auto parts and semiconductors.
What this means for investors and businesses
The sectors most exposed to a deteriorating USMCA environment are not hard to identify. Agriculture sits at the top of the list, given that dairy access is a named demand. The automotive sector is similarly vulnerable, with supply chains that cross the US-Mexico and US-Canada borders multiple times during a single vehicle’s assembly process.
For investors watching the auto sector specifically, the rules-of-origin question matters enormously. If the US succeeds in pushing stricter requirements for how much North American content a vehicle must contain to qualify for tariff-free treatment, manufacturers with cross-border assembly operations face real cost increases.
The steel and aluminum tariff disputes that are already running in parallel add another layer of complexity.
