The Border Is No Longer a Dividing Line. It Is a Shared Economic System

La frontera ya no es línea divisoria, es sistema económico compartido Revista interAlcaldes

This week’s five articles delivered a common warning: North America already shares a border economy, but it still lacks the governance required to manage it as a single system.

Mexico and the United States share a border economy that neither country yet governs as a system. The political line remains, but productive activity crosses it through highways, railroads, customs facilities, industrial plants, workers, and families whose lives depend on the territory functioning properly.

That conclusion connected the five articles published this week by interAlcaldes. The Twenty-First-Century Border: Trade, Technology, and Security brought logistics and protection into the same discussion. Customs Are No Longer Infrastructure: They Are a Competitive Advantage explained why border speed now influences where investment is located. Safe Cities Attract Talent; Violent Cities Drive Generations Away linked security to social stability. Municipal Security: The Challenge No Mayor Can Delegate returned responsibility to local government. Finally, Nogales, Arizona: When Security and Economic Development Move Forward Together turned the thesis into a territorial case.

Five Articles, One Economic Reality

The week produced five findings: infrastructure defines competitiveness; customs determines speed; security retains talent; municipalities sustain daily operations; and neighboring cities require permanent coordination. Treating these issues separately may simplify public administration, but it no longer explains how the real border works.

In 2025, merchandise trade between the United States and Mexico reached $872.8 billion, 3.9% more than in 2024. Trucks carried 73.6% of that value. Laredo handled 46.1% of bilateral truck freight, while Nogales processed approximately $25.4 billion, equivalent to 4% of that flow. These figures describe an industrial platform that depends on specific urban crossings.

“A slow customs facility, an unsafe city, or a vulnerable crossing does not stop only one municipality: it slows down a continental production chain.”

A part may cross the border for assembly, return as a component, and enter again inside a finished product. A duplicated inspection, a congested access road, or a local security crisis can therefore disrupt operations hundreds of miles away. The border is not the outer edge of two economies; it is where both prove whether they can work together.

Municipal Security Is Also Economic Policy

This week’s articles corrected an artificial separation: security and economic development do not move along different tracks. A violent city loses workers, students, families, and knowledge. A city with reliable institutions, orderly mobility, and emergency-response capacity reduces uncertainty and protects its supply chains.

That connection restores the central role of municipalities. Mayors do not negotiate the USMCA or control federal customs agencies, but they manage much of the border experience: access roads, land use, public transportation, preventive policing, emergency management, and urban services. When those capabilities fail, federal infrastructure loses efficiency.

Human mobility confirms that the territory cannot be understood only through freight. In 2025, 44.8 million pedestrian entries from Mexico into the United States were recorded. Behind that volume are workers, students, consumers, and families who need safe and predictable crossings.

The Agreement Remains in Force, but Confidence Is Being Tested

The July 1, 2026, joint review of the USMCA added political pressure. According to the Office of the United States Trade Representative, the United States did not agree to renew the agreement in its current form; however, the USMCA remains in force while negotiations continue. A third bilateral round between Mexico and the United States is scheduled for the week of July 20.

Legal precision matters, but the territorial interpretation matters more: no trade agreement can indefinitely compensate for congested crossings, uncoordinated inspections, local insecurity, or unplanned urban growth. The rules are negotiated in national capitals; their credibility is tested in Laredo, Tijuana, Nogales, Ciudad Juárez, Mexicali, and their neighboring cities.

“The border fails when each government manages its own side, but no one governs the system both countries share.”

Strategic Reading

Mexico and the United States need to move from occasional coordination to permanent border governance. That means sharing operational information, planning infrastructure through binational criteria, aligning emergency protocols, measuring crossing times and costs, and including municipalities in decisions that transform their territories.

This is not about erasing the border or weakening national responsibilities. It is about recognizing that sovereignty can coexist with intelligent management of interdependence. The region will be only as competitive as its slowest crossing and only as resilient as its most vulnerable city.

What Comes Next

Bilateral discussions already include rules of origin, steel, aluminum, automobiles, agriculture, labor, the environment, economic security, and regulatory compatibility. But the next stage will not be decided only at the USMCA negotiating table. It will also depend on border cities reducing delays, professionalizing security, and anticipating urban growth.

The border can no longer be evaluated only by what it prevents from crossing. It must be measured by its capacity to move goods securely, connect talent, sustain communities, and respond jointly to a crisis. It is not a dividing line; it is one of North America’s most important economic systems.

What decision should the governments of Mexico and the United States make first to begin governing the border as the shared economic system it already is?
