By assuming that trade relations are a zero-sum game in which one party must lose for the other to win, and that a trade deficit represents a loss while a surplus represents a win, President Trump reveals a simplistic view far removed from the dynamics of international trade.
Let’s imagine that the global economy is Central America, that Costa Rica imports more goods than it exports, and that other countries accept paper printed by its Central Bank — bills in colones — as payment for their exports. Furthermore, let’s assume that a good portion of their trade surpluses are used to buy Costa Rican government bonds and make deposits in its banks, accepting — due to confidence in the strength of its economy — lower interest rates than they might obtain in other markets, and that those debts can be paid with the same printed paper.
Trade deficits arise because a significant share of Costa Rican consumers and investors prefer to source final, intermediate, and capital goods from other Central American countries where prices are lower than at home. In other words, those deficits are the result of a national choice to enjoy a higher quality of life and greater productivity than what its economy would otherwise allow. Under these circumstances, Costa Rica, far from being a victim of other countries’ policies, would actually be enjoying levels of consumption above its means and economic growth beyond what its productivity would justify.
The willingness of those countries to hold the colones derived from their trade surpluses in Costa Rican government bonds and bank deposits results in lower interest rates in Costa Rica. This enables a higher sustainable level of public debt, greater investment at low cost to improve infrastructure and service quality, and lower interest rates for private investment — all of which contribute to a higher rate of economic growth without endangering macroeconomic stability.
In such a scenario, making imports more expensive through tariffs to boost local production competitiveness and eliminate trade deficits would, one by one, remove these advantages — amounting to nothing more than an own goal. This remains true even if Central American countries did not retaliate by restoring relative competitiveness to its starting point, and even if Costa Rican investors were not left uncertain about whether a future government might remove the tariffs.
The U.S. economy faces the world in a situation identical to that hypothetical scenario of Costa Rica. It takes advantage of the fact that with paper printed by its central bank — the dollar — can pay for the real production of other countries, allowing it to live far beyond its means. Far from being “cheated” by other nations, as Trump claims, the United States enjoys a standard of living well above its capacity precisely because of this. That does not mean the U.S. is cheating anyone, since it is thanks to its economic strength that the rest of the world accepts that paper as a means of payment and trusts in its government bonds and banking system.
Thus, by assuming that trade relations are a “zero-sum game” — where one must lose for the other to win — and that a trade deficit signals losing while a surplus signals winning, President Trump ignores these realities. He reveals a board-game level of simplification, detached from the complex chessboard that defines international trade dynamics. It is nothing less than a massive own goal.
Trade deficits are an economic problem for countries like Costa Rica, which must pay for their imports using foreign currency, often requiring them to take on debt and/or attract foreign investment through subsidies and tax exemptions. This combination of factors permanently threatens macroeconomic stability and forces governments to limit spending on infrastructure and social services to free up resources to cover interest payments and the growing fiscal costs of structuring an economy based on incentives to foreign companies.
Adding to the absurdity of Trump’s proposals, his goal is to achieve trade surpluses with every country in the world. However, the United States does not produce coffee or cocoa; thus, with some of the countries that export these products, running trade deficits is not only inevitable but also beneficial for the U.S. Many countries in the region, even without the advantages the United States enjoys, are unlikely to avoid trade deficits — for example, with oil-producing countries or those manufacturing goods that incorporate cutting-edge technologies. In such cases, raising tariffs could severely damage their economies.
Trump boasts that the countries affected by the tariffs are lining up to renegotiate, claiming that this was his goal. If so, it marks the beginning of an uncertain period, contaminated by threats and blackmail, with China standing by to benefit from the resentment against the United States. This scenario will severely affect private sector investment plans, employment, and economic growth — not only in the United States but around the world.
Far from "Making America Great Again" (MAGA), Trump is diminishing both his country and the world while violating every rule of international trade, both global ones under the WTO framework and those contained in free trade agreements like CAFTA-DR. This, of course, validates the concerns of those of us who argued that such treaties did not guarantee protected access to the U.S. market against political or geopolitical shifts. In international relations, the historical rule has been that decisions are not based on any moral or legal absolutes but rather on the exercise of power from unequal positions ("might is right"). This is why we always doubted that a free trade agreement with weaker countries would truly guide the behavior of the United States.
But Trump's overwhelming violations of international law (surprisingly and disappointingly supported by more than half of his country’s political establishment) strip the United States of any moral authority to criticize countries that do not act according to the rules. This imposing attitude, reaffirmed by Trump when he paraphrases emperors and tyrants — enemies of any democratic principle — who claimed that "those who save their country violate no law," leads us to a world where anything is permitted for those who hold power. From the perspective of the definition of civilization, a world where anything goes loses its value. It takes us back to the law of the jungle — the rule of the strongest, of violence and war, or of peace imposed by one over others, not through harmony and goodwill.
This is not a new “Washington Consensus”, now guided by the mercantilism typical of the 18th and 19th centuries, because in this case neither multilateral organizations like the World Bank or the International Monetary Fund nor other Western powers share Trump’s decisions. Far from consensus, today the most frequently heard word in those circles is “retaliation”.
Latin America will be affected by the potential decline in global GDP growth, the tariffs imposed on our exports, and the rise in interest rates resulting from inflation that could be triggered by higher import taxes in the United States. However, the region could benefit from the U.S. confrontation with its developed-world allies by strengthening economic ties with Europe, China, Japan, India, and other powers of the Global South — without, of course, abandoning the U.S. market.
To achieve this, our governments must stop meekly following Trump’s directives, such as preventing Huawei from competing to sell us 5G technology, participating in a shameful deportation policy that violates fundamental human rights, or undermining Panama’s absolute sovereignty over the Canal. What is needed is to build and implement a foreign policy with dignity, one that best serves the interests of each of our countries — not the whims of a single power.
