Executive Summary

The Shield of the Americas coalition, launched on March 7 by President Trump with 17 participating delegations at Trump National Doral, formalizes a military-first approach to counter-narcotics and explicitly targets Chinese geopolitical influence in the hemisphere. The exclusion of Brazil, Mexico, and Colombia, which together represent the majority of Latin American GDP, has divided the hemisphere along ideological lines. Defense Secretary Hegseth's March 30 unveiling of the "Greater North America" doctrine, defining all nations north of the Equator as a U.S. "immediate security perimeter," reinforces this realignment and has drawn public condemnation from Brazilian President Lula da Silva.

Venezuela's post-Maduro transition is producing rapid but fragile political change. The January 3 capture of Nicolas Maduro, his ongoing narcoterrorism trial in New York, the U.S. Embassy reopening in Caracas on March 30, and the reopening of opposition leader Maria Corina Machado's party headquarters on March 28 collectively mark a political opening not seen in over a decade. The Rodriguez transitional government's stability depends on sustained U.S. engagement and oil revenue, both of which face competing pressures from the Iran conflict and Washington's Middle East priorities.

Haiti's security crisis deepened with the Gran Grif gang's attack in Petite-Riviere de l'Artibonite in late March, which killed at least 70 people according to human rights organizations and displaced approximately 6,000. Gangs control approximately 90% of Port-au-Prince and are expanding into the country's agricultural heartland. The transition from the Kenya-led Multinational Security Support mission to a U.S.-backed Gang Suppression Force introduces additional operational risk.

Cuba faces a compounding energy and humanitarian emergency. The island received no oil imports between January and March 31, when a sanctioned Russian tanker delivered approximately 700,000 to 730,000 barrels to Matanzas, permitted by Washington on humanitarian grounds. The cargo provides only limited fuel coverage once refined, and OCHA's $94 million humanitarian appeal for two million Cubans faces a $68 million funding gap.

The Iran conflict is transmitting economic stress across the hemisphere through energy prices, fertilizer costs, and financial market volatility. Brent crude reached $112.78 per barrel by March 30, Chile implemented its largest fuel price increase in history, Argentina's country risk reached 637 points, and the WFP warned the crisis could push an additional 2.2 million people in Latin America into acute food insecurity.

The Ecuador-Colombia bilateral crisis introduced a new axis of instability in the northern Andes. Ecuador's escalation of "security tariffs" to 50% on Colombian goods, Colombia's retaliatory measures across trade, energy, and transport, and a 17-day border blockade disrupted a $2.8 billion annual trade relationship. Andean Community mediation on March 25 produced a framework for continued dialogue, but tariffs remain in effect.

The intensifying U.S.-China competition for hemispheric influence is reshaping economic and diplomatic alignments around critical minerals. Washington's $12 billion "Project Vault" strategic mineral reserve and supply agreements with Argentina, Ecuador, Mexico, Paraguay, and Peru represent a direct challenge to China's dominance in rare earth processing. Latin America's mineral wealth, including more than half the world's known lithium reserves, places the region at the center of this rivalry.
