The Economy Next Door
Mexico is, in almost every meaningful sense, an extension of the North American economy. It is the United States' largest trading partner — a status it claims ahead of Canada and China — and roughly 80 percent of its exports head north across the Rio Grande. That single figure explains more about Mexico's economic structure than almost any other: the country built its modern industrial base on proximity, not on the domestic market, and the architecture of that base is a creature of trade policy. The North American Free Trade Agreement, signed in 1994 and replaced in 2020 by the United States–Mexico–Canada Agreement, turned Mexico into an assembly platform for North American consumption. Automobiles, electronics, medical devices, aerospace components — the factories are in Monterrey, Saltillo, Querétaro and the maquiladora belt along the northern border; the consumers are overwhelmingly American.
The result is an economy with a curious dual character. Its manufacturing sector is sophisticated, export-oriented and deeply integrated into global value chains. Its domestic economy — service-heavy, informal, with a large share of workers outside the formal tax and social-security system — is considerably less dynamic. Informality touches roughly half the workforce, suppressing productivity, constraining the tax base and limiting the domestic demand that might otherwise cushion external shocks. Mexico is, in development terms, a middle-income economy that has struggled to break through to the next stage — efficient at making things for Americans, less successful at building broadly shared prosperity at home.
Remittances are the other structural pillar. Mexicans living abroad, overwhelmingly in the United States, send home tens of billions of dollars each year — a flow that in recent years has exceeded foreign direct investment and oil revenues, making it one of the largest sources of foreign exchange. For millions of households in Oaxaca, Michoacán, Guerrero and across the centre and south, that monthly transfer is the real safety net that formal institutions have not provided. It is also a vulnerability: remittances rise and fall with the US labour market and, more recently, with US immigration policy.
The Nearshoring Wager
The structural argument for nearshoring — the relocation of manufacturing closer to end markets — has been building since US-China trade tensions escalated in 2018 and accelerated sharply after the pandemic exposed the fragility of extended global supply chains. Mexico's case is, on paper, unusually strong. It shares a two-thousand-mile border with the world's largest consumer economy. It has preferential market access under USMCA. It has an established manufacturing workforce, a network of industrial parks and a time-zone alignment that no Asian competitor can match. When a factory in Monterrey has a problem, a manager in Detroit can fix it the same afternoon.
Investment flows have reflected this logic. Foreign direct investment into Mexican manufacturing has risen meaningfully, with particular strength in electric-vehicle supply chains — a telling signal, since EV manufacturing is one of the most complex and localisation-sensitive industries in the world. Chinese firms, alert to the tariff mathematics, have been among those exploring Mexican production as a route to US market access, a trend that Washington has noticed with some unease.
The honest case against nearshoring euphoria, though, is equally real. Mexico's infrastructure outside the industrialised north is inadequate: roads, ports, water supply and above all electricity generation have not kept pace with ambition. The state electricity company, CFE, operates under political and financial constraints that make reliable, affordable power for new industrial capacity genuinely difficult to guarantee. Water scarcity in the arid north — where most new factories want to locate — is a hard physical constraint that investment enthusiasm cannot dissolve. And security conditions in parts of the country impose costs and risks that do not appear in promotional literature but do appear in corporate risk assessments.
Institutional quality is the subtler constraint. The USMCA contains labour provisions that the US has already used to challenge specific Mexican facilities over union rights — a mechanism with teeth, as several automotive suppliers discovered. Regulatory predictability matters enormously to manufacturers planning decade-long capital commitments, and Mexico's record under recent administrations has been mixed. Energy policy in particular — the preference for state-owned providers over private and renewable generators — creates friction precisely where multinational manufacturers most need clarity.

What the Bet Pays Off
Mexico's nearshoring opportunity is real, but it is not automatic. Capturing it requires the infrastructure investment, institutional reliability and energy policy that have so far been partially absent. The country's geographic endowment — that long shared border, those trade agreements, that manufacturing heritage — is a gift that no competitor in Southeast Asia or South Asia can replicate. But geography is a starting position, not a destiny.
The prize, if the bet pays, is considerable: a chance to move more of the population into formal, productive employment, to deepen the domestic economy and to break the cycle of informality and stagnant wages that has kept so many Mexicans dependent on remittances from relatives who left. The next decade will show whether Mexico can convert its structural advantage into structural transformation — or whether the nearshoring wave breaks against the rocks of inadequate power grids and institutional drift.
