USMCA Non-Renewal Puts North American Energy Flows in Limbo
Washington's expected exit from the North American trade pact opens a potential decade of renegotiation, threatening crude and gas supply routes from Canada and Mexico.
NYMEX gasoline futures were down 12.61% at $3.05/gal as of August 31, one of the sharpest drops in the North American products complex, as traders priced in growing supply disruption risk ahead of the United States' expected decision not to renew the United States-Mexico-Canada Agreement.

Washington is set to formally announce it will not extend the USMCA, beginning what Atlantic Council analysts call a potentially decade-long renegotiation over the future of North American trade. The prolonged uncertainty is particularly damaging for capital-intensive energy infrastructure projects, which require sustained market-access visibility before sponsors commit to final investment decisions. ICE Brent crude front-month eased 0.80% to $89.03/bbl and NYMEX WTI front-month slipped 0.50% to $84.37/bbl as of August 31.4[LIVE PRICES]
The pact, six years old and up for mandatory review, could be extended for a further sixteen years, or replaced by a far more limited arrangement if talks stall. US, Mexican, and Canadian officials convened on July 1 (2026-07-01) to open that review, with energy trade among the highest-value items on the table.5
Mexico's state-owned Pemex carries significant exposure. Already straining under deteriorating finances, the company would see its primary export channel put at risk if preferential access to US refineries were to lapse. For Canada, the concern is analogous: heavy Albertan crude grades flow to US refineries configured specifically for those grades, and under most-favored-nation tariffs rather than preferential treatment, those barrels would likely seek alternative buyers in Asia.5,1
Mexico's energy diplomacy has been moving beyond Washington's orbit. Between May and August 2025, Mexico sent more than $3bn-worth of cheap fuel to Cuba, triple the volume shipped under former President Andrés Manuel López Obrador, according to estimates from MCCI, an NGO. Pemex's finances are deteriorating. Yet the government has continued and expanded those Cuba shipments, suggesting geopolitical priorities are overriding balance sheet discipline.1
The Cuba fuel flows are already a source of friction with Washington. The Trump administration has shown a willingness to use economic coercion to enforce hemispheric policy, bringing alleged Venezuelan kingpins to the United States and placing fresh tariffs on China. Striking Mexico, America's largest trading partner, carries far higher costs than confrontations with smaller economies, but the political appetite for pressure appears undiminished.1
Mexico is responding with diversification. The government has placed tariffs on Chinese imports, aiming to protect domestic industries and attract foreign investment away from US-centered supply chains. The World Cup co-hosting role this summer has given Mexico City a high-visibility platform. Foreign Policy observed that as the United States closes itself off from the world, its co-host is doing the opposite.6,3
Progressive political movements across the hemisphere see the renegotiation as an opportunity. Foreign Policy reported that progressives in the region are plotting a return to influence as the USMCA review unfolds, with Mexico City and Ottawa both signaling they intend to use the process to extract concessions on energy investment rules and dispute resolution.7,6
Canada faces its own pressures. Ottawa is navigating domestic politics while trying to preserve a trade relationship that anchors its energy export economics. Any extended gap in the USMCA framework would force a reassessment of pipeline and export investment that Canadian energy companies had structured around guaranteed US market access.4,5
The World Cup has complicated the diplomatic calendar. The Trump administration has alerted federal agencies that they may turn to telework as the United States prepares to stage 78 matches across 11 US cities alongside Canada and Mexico. That logistical cooperation between the three governments is running in parallel with tense trade negotiations.2
Mexico's fuel shipments to Cuba, now running at triple the pace of the previous administration and sustained despite Pemex's financial strain, are the immediate flashpoint. If Washington links those flows to the USMCA renegotiation, energy trade could face disruption well before any new framework is agreed.1,4
