Latin American regional integration

Originally published in March 2017. Updated in April 2026 with revised statistics, sources and additional context.

In March 2017, as the newly inaugurated Trump administration threatened to reshape trade with Mexico, I made an argument that sounded provocative at the time: perhaps Latin America should regard the confrontation not only as a problem, but as an opportunity.

The point was never that economic conflict with the United States would somehow be good for Mexico. Mexico’s commercial relationship with its northern neighbor was—and remains—too important for such a simplistic conclusion. The more interesting question was why Mexico, and Latin America more broadly, had allowed so much of its economic destiny to depend on decisions taken elsewhere.

That question is still worth asking.

Latin American regional integration has been discussed for almost as long as the region has consisted of independent republics. Yet Latin America continues to behave economically and politically as a collection of separate countries whose combined influence is considerably smaller than their collective resources would suggest.

That is the paradox. Latin America is not short of land, people, natural resources, agricultural capacity, industrial centers, universities, banks or access to international markets. What it has historically lacked is the ability to combine those assets with the consistency and institutional discipline necessary to turn size into power.

The region does not need to become a single country to change that. Nor does it need to turn its back on the United States, Europe or China. But it would benefit from asking a deceptively simple question: what would happen if Latin America’s economies became considerably better connected to one another?

A Continent-Sized Opportunity

Geography makes the argument for integration difficult to ignore.

Latin America stretches from Mexico through Central America and across most of South America to Patagonia. It contains enormous Atlantic and Pacific coastlines, some of the world’s great river systems, vast agricultural territories, tropical forests, deserts, mountains and an extraordinary concentration of minerals and other natural resources.

Brazil is one of the world’s major producers of iron ore and agricultural commodities. Chile and Peru are among the leading producers of copper. Argentina, Bolivia and Chile possess some of the world’s most important lithium resources. Mexico has developed a sophisticated manufacturing economy closely connected with North American supply chains. Panama sits astride one of the most important shipping routes on earth.

Smaller countries have found their own niches. Costa Rica, for example, has developed significant medical-device, technology and services industries despite having only a fraction of the population of Brazil or Mexico.

Individually, these are impressive accomplishments. Collectively, they suggest something much larger.

When the original version of this article was written, some of its economic figures were too generous. The World Bank’s historical data put the GDP of Latin America and the Caribbean at about $5.87 trillion in current dollars in 2017, rather than the $9.5 trillion stated in the original article. (World Integrated Trade Solution)

That correction does not undermine the argument. If anything, it makes it more interesting. A regional economy measured in trillions of dollars has substantial weight, but its influence depends on how effectively those trillions interact.

The World Bank’s 2017 trade figures show how heavily the region’s commerce was oriented outward. The United States alone absorbed more than 44% of Latin American and Caribbean exports that year. China accounted for almost another 10%. Brazil and Argentina, despite being among the largest economies inside the region, each represented only a small share of the region’s total export market. (World Integrated Trade Solution)

That is a remarkable imbalance.

A region can hardly aspire to substantial economic autonomy if neighbouring economies remain secondary markets for one another.

More Than 600 Million People, But Not Yet One Market

Latin America also has something businesses spend fortunes trying to acquire: scale.

By 2017, the wider Latin American and Caribbean region contained well over 600 million people. The United Nations’ demographic work confirms the extraordinary scale of the region and its continuing importance in the global population. (United Nations Population Division)

Population alone, of course, does not create an integrated market. India is one country. Latin America is not. Taxes differ. Commercial laws differ. Customs procedures differ. Professional qualifications differ. Infrastructure changes at borders. Political priorities change every few years.

Yet Latin America begins with advantages that other regions have had to work much harder to overcome.

Most of the region speaks Spanish. Brazil speaks Portuguese, a closely related language. National identities are strong, but there is also an unmistakable cultural connection running through much of the region. This does not erase the enormous Indigenous, African, European, Asian and Middle Eastern influences that have shaped individual countries. It simply means that economic integration would not have to bridge the linguistic divisions that Europe confronted when constructing its common market.

Europe is particularly instructive because its integration was never based on the proposition that Germans should stop being German or Italians should stop being Italian. The project was built on the more practical idea that national identity could coexist with increasingly integrated commerce.

Latin America does not need a Latin American flag flying over a new continental capital to obtain many of the same economic advantages. Latin American regional integration could proceed through something much less dramatic: fewer barriers, better infrastructure, deeper capital markets, interoperable systems and a willingness to treat neighbouring countries as genuine commercial partners.

That sounds less inspiring than Bolívar’s dreams of continental unity.

It may also be considerably more achievable.

The Real Prize Is Economic Scale

The great advantage of integration is not sentimental. It is scale.

Consider a Costa Rican company. Its domestic market consists of only a few million people. A Colombian company begins with a much larger population, but still operates within a market dwarfed by the United States, China or the European Union.

Remove enough friction between those economies and the calculation begins to change.

A company that can efficiently sell across several hundred million consumers has different incentives to invest in factories, technology, logistics and research. A regional bank operating under more compatible rules can finance larger projects. Manufacturers can source components from several countries. Professional-service companies can expand without repeatedly rebuilding themselves around different regulatory systems.

This is precisely where much of Latin America’s integration problem lies.

The Inter-American Development Bank has argued that the region’s weak participation in global value chains is connected to inadequate logistics, regulatory obstacles, shallow regional integration and institutional weaknesses. Its research found that countries sharing deeper regional integration arrangements tended to attract more foreign investment associated with global value chains. (Inter-American Development Bank)

The lesson is important because it contradicts an old misconception about regionalism.

Integration does not have to mean protectionism.

A stronger Latin American market should not be designed to hide local businesses from foreign competition. It should make them better able to compete with it.

Mexico Does Not Need to Choose Between North and South

This is one point on which I would change the language of my original 2017 article.

I wrote then that Latin America should “cut the umbilical cord” with the United States and Europe. It was rhetorically satisfying, but economically too crude.

Mexico does not become stronger by damaging one of the most sophisticated cross-border manufacturing relationships in the world. The United States is not simply a customer for Mexico; the two countries are connected through supply chains in which components can cross the border repeatedly before becoming finished products.

The more sensible objective is diversification rather than divorce.

Mexico can remain deeply integrated with the United States and Canada while developing much stronger commercial relationships with Colombia, Brazil, Chile and Central America. Brazil can sell iron ore and agricultural products to China while becoming better connected to other South American economies. Costa Rica can export medical devices to the United States while giving its companies easier access to Latin American markets.

These are not mutually exclusive strategies.

Indeed, the World Bank’s figures from 2017 illustrate why the distinction matters. The United States was overwhelmingly the most important export destination for the region, while trade with individual Latin American partners remained relatively modest. (World Integrated Trade Solution)

The objective of Latin American regional integration should therefore not be independence understood as isolation. It should be independence understood as optionality: the ability to trade with Washington, Beijing, Brussels and one another without excessive dependence on any single relationship.

That is a much more useful form of sovereignty.

The Roads Still End at the Border

None of this works without infrastructure.

Latin America can sign as many declarations of regional brotherhood as its presidents wish, but a declaration does not move a container from Brazil to a Pacific port. It does not reduce the time a truck waits at a Central American border. It does not connect electrical grids or make customs databases communicate with one another.

The region needs physical integration.

It needs roads that are designed as international economic corridors rather than merely domestic projects. It needs efficient ports, rail where rail is economically justified, airports, modern border facilities, reliable electricity and high-capacity digital networks.

The scale of the challenge is enormous. CAF, the Development Bank of Latin America and the Caribbean, estimated in 2024 that the region would need more than $2.2 trillion in infrastructure investment through 2030 across transportation, energy, telecommunications, water and sanitation. CAF also noted that the region remained materially behind Europe and Asia in infrastructure integration and connectivity. (CAF)

This is where discussions about regional power become less romantic.

Integration is not principally a matter of presidents holding summits. It is highways, ports, customs offices, power lines, cables and computer systems.

The European Union’s success as an economic bloc owes at least as much to the boring machinery of integration as to its political institutions.

Latin America has traditionally been much better at announcing the former than building the latter.

Courts Are Infrastructure Too

There is another form of infrastructure that cannot be photographed from the air.

The judicial system.

When I wrote the original article, I argued that Latin America had not given enough credit to the economic importance of effective courts. I still think that is one of the central challenges confronting any serious integration project.

A highway allows merchandise to travel from one country to another. A court gives the businesses trading that merchandise confidence that their agreements mean something.

If contracts take years to enforce, companies price that uncertainty into transactions. If property rights are unpredictable, investors demand higher returns to compensate for the risk. If political connections matter more than rules, capital finds somewhere else to go.

The IDB has made much the same connection. Its work on Latin America’s participation in international production chains has identified the rule of law alongside logistics and regional integration as a factor affecting the region’s ability to attract investment. It noted stark differences in the time required to enforce contracts between Latin America and competing regions. (Inter-American Development Bank)

An effective judicial system must work in both directions. Civil and commercial disputes need reliable adjudication, but criminal justice must also function. Businesses cannot prosper where organized crime makes transportation dangerous, extortion becomes another operating cost or governments lose control over parts of their territory.

At the same time, effectiveness cannot become an excuse for abandoning due process. Courts gain legitimacy by being both capable and fair. Prisons that are inhumane and criminal systems that disregard fundamental protections do not strengthen institutions; they weaken confidence in them.

Regional integration therefore requires more than removing tariffs. It requires countries in which rules can be trusted.

Latin America Has Institutions. What It Often Lacks Is Execution

The region is hardly starting from zero.

It has Mercosur. It has the Pacific Alliance. It has the Central American Integration System and the Andean Community. It has the Inter-American Development Bank. It has CAF and the Central American Bank for Economic Integration.

In other words, Latin America has spent decades creating institutions intended to bring it closer together.

This makes the continued weakness of Latin American regional integration more revealing, not less.

The obstacle is not a shortage of acronyms.

It is implementation.

Governments find it relatively easy to sign declarations supporting integration. The real test arrives when integration requires accepting a neighboring country’s standards, changing a customs procedure, exposing a protected domestic producer to competition, funding a project whose benefits extend beyond the next election, or surrendering a small measure of administrative autonomy in exchange for a larger market.

That is where regional enthusiasm often meets national politics.

The Problem With Nationalism

Latin America’s national identities are strong, and they should be.

There is no reason for Costa Rica to become less Costa Rican, Mexico less Mexican or Brazil less Brazilian merely because their economies cooperate more closely.

The danger comes when national identity is used to defend economic fragmentation for its own sake.

Small economies can become absurdly protective of industries that could never achieve sufficient scale domestically. Larger countries can convince themselves that they do not need their neighbors. Old diplomatic disputes become permanent excuses for mistrust.

The result is a region whose individual countries sometimes fight vigorously for small pieces of economic territory while larger global powers negotiate from vastly stronger positions.

The challenge is not to abolish nationalism but to put it in perspective.

A domestic company should not deserve permanent protection merely because its owners carry the right passport. Consumers should not be required to subsidies inefficiency in the name of patriotism. Governments should be able to defend legitimate national interests while recognizing that some interests are better advanced collectively.

Europe has spent decades arguing over precisely these tensions. Latin America would undoubtedly do the same.

Integration is difficult because it requires governments to think beyond their borders without pretending those borders no longer matter.

A Dream That Is Two Centuries Old

There is, of course, nothing original about dreaming of Latin American unity.

Simón Bolívar understood the problem almost two centuries ago. The newly independent republics of the Americas were politically fragile and surrounded by much larger powers. Cooperation seemed an obvious answer.

History took another direction.

National republics consolidated. Regional rivalries developed. Economies turned outward toward Europe and later the United States. Attempts at political or economic union repeatedly collided with geography, domestic politics and conflicting national interests.

Modern integration initiatives have achieved considerably more than Bolívar’s failed congresses, but they remain incomplete.

Perhaps the mistake has been imagining integration too dramatically.

Latin America does not need to wake up one morning as a federation extending from the Rio Grande to Tierra del Fuego.

A truck crossing a border in minutes rather than hours is integration.

A Colombian professional being able to work more easily in Peru is integration.

A Brazilian manufacturer sourcing efficiently from Chile is integration.

An Argentine company raising capital in a deeper regional financial market is integration.

Electricity flowing between neighboring countries when one has excess capacity is integration.

Compatible digital signatures are integration.

A commercial judgment being enforceable reliably across borders is integration.

None of these developments requires the destruction of national identity. Together, however, they could fundamentally alter the economics of the region.

What 2017 Was Really About

Donald Trump’s approach toward Mexico was the event that prompted the original article. But in retrospect, the more enduring subject was never one American president.

Political administrations change. Trade agreements are renegotiated. Tariffs rise and fall. Commodity cycles come and go.

Geography is considerably more stubborn.

Latin America will remain where it is. Its hundreds of millions of inhabitants will remain a substantial world market. Its mineral deposits, agricultural land, industrial centers, ports and universities will continue to represent extraordinary economic potential.

The unresolved question is whether the region can organize those assets more effectively.

The greatest threat to Latin America’s potential is therefore not necessarily a policy announced in Washington, Brussels or Beijing. It is the possibility that another generation will pass while Latin American countries continue to speak about integration more enthusiastically than they practice it.

That was the frustration behind my original article in 2017.

It remains the part of the argument that has aged best.

There is an enormous difference between having resources and having power. Resources are things a country possesses. Power depends on whether those resources can be organized, financed, protected, transported and deployed toward a coherent objective.

Latin America unquestionably possesses the first.

Latin American regional integration is ultimately a question of whether it can achieve the second.

I called the region a sleeping giant in 2017. The metaphor still works, although perhaps the diagnosis was incomplete. The giant is not asleep because it lacks strength. It is asleep because its limbs have never quite learned to move together.

That is a much harder problem than confronting any particular tariff.

It is also a far more consequential one.
