On December 4, 2025, U.S. Trade Ambassador Jamieson Greer announced in an interview with Politico that the U.S. government, under U.S. President Donald Trump, is contemplating a full withdrawal and renegotiation of the USMCA trade agreement with Canada and Mexico. The trilateral pact, which replaced NAFTA in 2020, currently facilitates $1.8 trillion in tariff-free trade among the three nations, making it a critical pillar for North American economic integration.
Greer explained that the agreement was designed with a built-in review period, allowing for revisions or even exit if the terms no longer serve U.S. interests. The Trump administration is considering splitting the USMCA, negotiating distinct deals with Canada and Mexico separately, a radical departure from the integrated approach established since the 1990s. This move follows recent tensions, especially with Canada, who has faced U.S. tariffs on steel and aluminum, and diplomatic friction initiated by political disputes over trade policy.
This announcement comes amid fresh negotiations scheduled to start in July 2026, intended to update or revise the USMCA. However, Canadian Prime Minister Mark Carney and Mexican President Claudia Sheinbaum have expressed caution and a lack of urgency, signaling potential challenges for upcoming talks. High-stakes trade hearings underway in Washington reveal strong support from American industry groups advocating for the continuation and modernization of the trilateral agreement.
U.S. industry leaders, representing sectors employing millions, have warned that exiting the agreement could be economically catastrophic for all three countries. Kevin Brady, co-chair of the Coalition for North American Trade, emphasized that USMCA is vital for maintaining competitive advantages against China and sustaining cross-border supply chains, particularly in automotive, steel, and agricultural sectors.
The Trump administration's tariff policies have disproportionately targeted Canada with 50% tariffs on steel and aluminum, whereas Mexico's exports largely remain tariff-free under USMCA rules. This divergence underscores the administration’s justification for treating the partners differently, citing differences in economic structure, labor, and export profiles.
Industry advocates call for caution, interpreting Trump’s threats as potential negotiating tactics rather than firm decisions. However, the uncertainty has already injected volatility into markets and raised concerns among investors about the longer-term stability of North American trade relations.
The potential dismantling of the USMCA agreement threatens to unravel decades of trade liberalization that have integrated supply chains across the continent. Given that 2022 data showed $1.8 trillion in tariff-free trade flows, any disruption could impose significant costs on manufacturers who rely on just-in-time supply chains spanning the three countries.
U.S. President Trump’s insistence on “only good deals” reflects his broader America-First trade philosophy, valuing bilateral leverage over multilateral cooperation. Moving forward, if the U.S. opts to negotiate separate bilateral agreements, trade policy complexity will increase, potentially raising compliance costs and erecting new barriers that could diminish the competitiveness of North American exports globally.
Such a shift could erode the economic efficiencies gained through the integrated USMCA framework. Canadian and Mexican economies, heavily intertwined with the U.S., rely on the predictability and tariff-free nature of the agreement to attract investment and support jobs. A breakdown or fragmentation of the pact could trigger supply chain realignments, delayed investments, and reduced trade volumes.
Looking ahead, the strategic interplay between the U.S., Canada, and Mexico will be crucial. The scheduled meeting between Prime Minister Carney and U.S. President Trump at a FIFA World Cup draw event in Washington may set the tone for negotiations, but expectations remain tempered given prior tensions and the political complexities surrounding the pact.
Financial markets and industry stakeholders will closely watch whether the Trump administration proceeds with withdrawal or uses the threat as leverage to secure concessions, such as enhanced labor provisions or enforcement mechanisms. Given the significant economic costs at stake—$1.8 trillion in trade volume and millions of jobs supported—any move away from the trilateral agreement framework could destabilize North American trade and complicate U.S. efforts to counterbalance China economically.
In conclusion, while U.S. President Trump's transactional approach to trade negotiations aims to optimize perceived national gains, the potential withdrawal from the USMCA presents considerable risks. It undermines a tested multilateral framework that has facilitated seamless trade flows for years and could introduce uncertainty, elevate tariffs, and ultimately hamper the competitiveness of the North American economies in the evolving global landscape.
