Intra-regional trade accounts for over half of each North American nation’s exports, with supply chains crossing borders an average of seven times before final assembly. If the USMCA framework remains unchanged, the existing architecture of co-production will continue to operate without formal institutional reinforcement.
What if the most powerful economic force of the 21st century isn’t a nation, but a continent? In 1820, the U.S. was a fragmented collection of states with weak federal ties—until the American System, built on internal improvements, a national bank, and protective tariffs, forged a unified economy. A century later, the Federal Reserve was designed not as a single entity, but as a network of regional banks, recognizing that economic strength flows from interconnected nodes. Now, in 2026, North America stands at a similar inflection point. The USMCA review is not about preserving a trade deal—it’s about completing a century-long project of continental integration. Consider this: when a car rolls off an assembly line in Silao, Mexico, it contains parts made in Indiana, Michigan, and Texas. When a chip is packaged in Monterrey, it enables devices used in hospitals from Boston to Vancouver. This isn’t trade; it’s co-production on a continental scale. And yet, we still think in national terms. The real story hiding in the Brookings data is that North America—U.S., Canada, Mexico—already functions as a single economic organism. Over 13 million U.S. jobs depend on trade with Canada and Mexico; more than 50% of each nation’s trade is intra-regional; and supply chains cross borders an average of seven times before final assembly. This is deeper integration than existed among EU members before the euro. The 2026 review is the chance to formalize what already exists: a North American industrial ecosystem capable of rivaling any power on Earth. The irony? The threat that could unite the continent isn’t a war or a depression—it’s a single policy decision. Renew the USMCA not for another 16 years, but as a permanent foundation, like the U.S. Constitution or the Treaty of Rome. Because history shows that empires don’t fall from invasion—they unravel from disconnection. And the next great economy may not be a country at all, but a continent that finally realized it was one all along.
