★ THE ASSEMBLY LINE

USMCA Review Begins July 1. The trade agreement governing $1.8 trillion in annual commerce between the U.S., Mexico, and Canada faces its first mandatory review in 15 days. All three countries must agree to extend it or it enters annual reviews that could lead to expiration.

Auto Industry Faces Highest Risk. The USMCA requires 75% regional value content for vehicles to qualify for duty-free treatment. The U.S. is expected to push for tighter rules and stronger enforcement against Chinese-origin inputs routed through Mexico.

Mexico FDI Surges Despite Uncertainty. Foreign direct investment in Mexico hit $40.9 billion through Q3 2025 — already exceeding the full-year 2024 total. Manufacturers are betting that North American integration survives the review.

It's not a stimulus check. It's not a tax cut.

Nor is it the $1,000 "Trump Accounts" for American newborns.

Trump calls it "American brilliance at its best"… and the CEO of Coinbase says it's opening up a "golden age for freedom" in America.

Jeff Brown was consulted by members of Congress to help shape this "gift."

$1.8 Trillion in Trade. 15 Days Until the Review. Here’s What Happens Next.
The USMCA governs how North American manufacturing works. On July 1, all three countries decide whether to keep it.

Every Ford F-150 has parts that cross the U.S.-Mexico border multiple times before the truck is finished. Every Caterpillar machine ships components through USMCA supply chains. Every can of Corona crosses the border duty-free under the same agreement.

That agreement is the USMCA — the United States-Mexico-Canada Agreement. It replaced NAFTA in 2020. It governs $1.8 trillion in annual trilateral trade. And unlike NAFTA, it has a built-in expiration mechanism. Every six years, all three countries must agree to extend it — or it starts dying.

The first review is July 1. That’s 15 days from today.

Here’s how the sunset clause works. Under Article 34.7, if all three countries agree, the USMCA extends for 16 more years — through 2042. If they don’t agree, it enters a cycle of annual reviews. And if no deal is reached during those reviews, the agreement expires by 2036. Any party can withdraw with six months’ notice.

That matters because USMCA isn’t just a trade deal. It’s the operating system for North American manufacturing. The agreement sets rules of origin that determine whether a product crosses the border duty-free or gets hit with tariffs. For vehicles, the threshold is 75% regional value content. For steel and aluminum, it requires North American melting and pouring. For agriculture, it governs market access worth tens of billions.

Trade analysts at CSIS and the Atlantic Council outline three scenarios.

Scenario one: renewal with revisions (roughly 50% probability). The three countries renegotiate and reach a new deal by late 2026. Rules of origin tighten — particularly on Chinese-origin inputs routed through Mexico. Labor enforcement strengthens. The core framework holds. This is what the market is pricing in.

Scenario two: annual reviews (roughly 35%). No deal is reached on July 1. The agreement stays in force but enters a cloud of sustained uncertainty. Investment decisions get delayed. Companies start building contingencies.

Scenario three: collapse (roughly 15%). A party withdraws. Trade reverts to WTO terms. Tariffs spike across the board. The Atlantic Council calls this the most disruptive outcome for the auto sector. CSIS estimates it could add thousands of dollars to the cost of a single vehicle.

★ The China Variable

The biggest flashpoint is Chinese investment in Mexico. U.S. negotiators want anti-transshipment rules to prevent Chinese goods from entering the U.S. duty-free through Mexican assembly operations. Canada’s growing trade ties with China have also raised concerns.

The goal is what CSIS calls “Fortress North America” — a continental supply chain that excludes Chinese components. If those provisions get baked into the renewed agreement, it strengthens the reshoring case for every manufacturer we’ve covered.

The stocks with the most USMCA exposure are the automakers. Ford, GM, and Stellantis all run deeply integrated cross-border supply chains. A disruption to duty-free treatment would hit their margins hardest. We covered Ford’s F-150 two weeks ago — that truck’s supply chain is a perfect example of how USMCA makes American manufacturing work.

Beyond autos, watch Constellation Brands (NYSE: STZ) — the importer of Corona and Modelo, which depend on Mexican production and duty-free access. And Canadian Pacific Kansas City (NYSE: CP) — the only railroad connecting all three USMCA countries, which benefits directly from cross-border trade volumes.

The most likely outcome is renewal with tighter rules. That’s good for American manufacturers who already source regionally. It’s bad for companies relying on Chinese components routed through Mexico. And it’s a tailwind for every reshoring story we’ve covered — because a stronger USMCA means a higher wall around North American production.
