Latin America Daily Security Brief

The U.S. Treasury Department on March 18 issued a broad license authorizing PDVSA and any majority-owned subsidiary to sell Venezuelan oil to U.S. companies, with some entity-specific restrictions. The move is explicitly linked to the global oil price spike driven by the ongoing Iran conflict and concerns about sustained Hormuz Strait closure.

Former Obama-era State Department energy envoy David Goldwyn told reporters the market impact will be limited in the short term — 'pennies per gallon' — because Venezuelan production capacity remains badly degraded after years of sanctions and neglect. The critical date is late May: if the Strait of Hormuz remains closed beyond that point, Goldwyn says 'the shortfall will increase significantly.'

Potential participants named in reporting include companies from India, Europe, and Brazil, plus major energy firms with prior Venezuela exposure. Venezuela and PDVSA bonds jumped immediately on the news (Reuters, March 18). The Trump administration is separately seeking $100 billion in energy sector investment in Venezuela.

A concurrent analytical report — cited by multiple outlets — concludes that Venezuela's security institutions are 'beyond reform,' a finding with direct implications for any company evaluating operational exposure. The Padrino López federal indictment in D.C. (filed 2019) for allegedly facilitating cocaine flights in exchange for bribes over $60,000 per flight remains unresolved and active.

Front-month Brent crude remains above $110 — higher than when Russia invaded Ukraine and matching 2008 financial crisis levels. The waiver spiked Venezuelan bonds but had zero impact on the oil price. The market read is clear: traders are not pricing in meaningful Venezuelan supply relief any time soon. The infrastructure deficit is too deep and the political conditions too uncertain for capital to flow at the speed Washington needs.

Colombian Defense Minister Pedro Sánchez confirmed on March 18 that the unexploded munition found on Colombian soil near the Sucumbíos border was consistent with an Ecuadorian military operation conducted on March 3 in a sector known as 'La Isla,' just meters from the Colombian frontier. The meeting between defense ministers lasted approximately 90 minutes.

Both governments agreed the March 3 operation was conducted in Ecuadorian territory and was legally consistent with non-international armed conflict frameworks. A binational technical commission will conduct an in-situ verification of how the device crossed into Colombian territory. Colombian military forces subsequently conducted a controlled detonation of the munition.

Despite the diplomatic de-escalation, Colombian President Gustavo Petro initially told a ministerial council that 'they are bombing us from Ecuador and it is not the armed groups' — a statement that framed Ecuador's Noboa government as an aggressor. This framing has damaged the political environment for Petro's 'Total Peace' negotiations, with analysts at the Colombian outlet Crisis de Colombia identifying five specific fault lines now under stress at active negotiating tables.

Separately, Colombia's Defense Ministry confirmed that the Clan del Golfo, ELN, and FARC dissidents are actively pressuring mining communities in Bajo Cauca, Antioquia, where a miners' strike has now entered its third day in Caucasia. U.S. DNI Tulsi Gabbard named ELN and FARC dissidents as a 'tangible threat' to regional stability in her annual threat assessment.

Mexican Security Minister Omar García Harfuch announced on March 18 that Angel Esteban Aguilar — known as 'Lobo Menor' and identified by Ecuador's Interior Minister John Reimberg as a leader of the Los Lobos criminal organization — was arrested at Mexico City's international airport. He was subject to an Interpol red notice and is wanted in connection with the July 2023 assassination of presidential candidate Fernando Villavicencio.

Colombian President Petro called Aguilar 'one of the world's most notorious assassins' and praised the trilateral cooperation between Colombia, Ecuador, and Mexico that produced the arrest. García Harfuch specifically described Aguilar as linked to 'drug trafficking, extortion, and homicide.' Aguilar was transferred to Colombian custody.

The arrest is a significant intelligence win, but analysts note it does not resolve Ecuador's structural gang problem. Los Choneros leader Adolfo Macías — recaptured in June 2025 after a dramatic prison escape — remains in custody, yet gang violence continues to shift from Pacific coastal provinces into interior cities. Ecuador launched a new two-week security operation covering four provinces on or near the Pacific coast on Sunday.

The U.S. Pentagon confirmed this week that Ecuador has 'set the pace' in the 17-country anti-narco coalition ('Shield of the Americas'), with joint U.S.-Ecuadorian military operations ongoing following Noboa's authorization. The Pentagon official stated the U.S. has delivered capabilities to Ecuador 'that it otherwise would not have had.' March 4 operations near the Colombian border were the first publicly acknowledged joint combat-support actions.

The security environment following the February killing of CJNG leader Nemesio Oseguera Cervantes ('El Mencho') continues to be the dominant domestic security story. El País Mexico reported that the Attorney General's office has abandoned its forward operating site near where the CJNG leader was killed, citing inadequate minimum security conditions — a signal that the post-Mencho power vacuum is already generating instability in Jalisco.

The AG retreat from Jalisco deserves more attention than it is getting. When Mexico’s federal law enforcement apparatus determines that the area where it just killed the country’s most powerful cartel leader is too dangerous to maintain a presence, that is not a routine operational decision — it is an admission that the state does not control the territory. The CJNG succession fight is happening in a jurisdiction where federal investigators have effectively conceded the ground. For anyone with operations, personnel, or assets in Jalisco outside the Guadalajara metro area, this is the single most important signal in today’s brief. The security vacuum left by El Mencho’s death is not being filled by the state. It is being contested by armed groups with no central command structure and no incentive to de-escalate.

Security Minister García Harfuch has moved to restore Mexico-DEA intelligence cooperation that atrophied during the López Obrador administration. El País Mexico characterized this as a deliberate 'thaw,' with Mexico having arrested or killed dozens of Sinaloa and CJNG members in the past year. The relationship will be tested by the FIFA World Cup Play-Off Tournament, which begins in Guadalajara and Monterrey on March 23 — four days away.

Colima state is finalizing its Semana Santa security operation (Easter week), coordinating the Guardia Nacional, XX Military Zone, VI Naval Region, and state health and tourism agencies. The operation targets high-traffic tourist corridors in a state that has historically been one of Mexico's most violent per capita.

Infobae reported, citing a New York Times investigation, that Sinaloa Cartel members are now taking seriously the possibility of a U.S. armed incursion and have intensified cyber and threat operations targeting U.S. military personnel. This follows months in which cartels had dismissed direct U.S. military action as rhetoric.

This is a significant behavioral shift. For months, cartel leadership dismissed direct U.S. military action as political theater. The El Mencho operation and Pentagon officials explicitly declining to rule out ground deployments changed that calculus. Cartels are now adapting their operational security, communications, and threat posture to account for a scenario they previously considered impossible. The cyber and threat operations targeting U.S. military personnel represent the first observable defensive adaptation by a major TCO to perceived U.S. military escalation.

Cuba restored power after a 29-hour nationwide blackout, Reuters reported March 18, the latest in a series of catastrophic grid failures driven by the near-total loss of Venezuelan oil supply since January. The U.S.-Cuba talks described by Reuters as aimed at 'defusing the crisis' remain nascent and unresolved.

Secretary of State Marco Rubio publicly pushed back against a New York Times report suggesting Washington was open to a negotiated transition that preserved some Castro-era institutional structures. Rubio's position aligns with his consistent line that the crisis is self-inflicted by Cuba's own political model — not a product of U.S. pressure. The internal White House debate over this point has not been resolved.

The humanitarian situation is deteriorating in a measurable way. Aid group directors cited by ABC News's Good Morning America used the phrase 'tipping point' on March 18 to describe conditions on the ground, with food, medicine, and fuel shortages compounding across all provinces. Multiple news organizations noted that Portugal is routing tourists out via the Dominican Republic due to the infrastructure collapse.

China's Foreign Ministry has publicly pledged support 'to the best of our ability' to Havana, but analysts at Naked Capitalism and the Wilson Center agree that neither China nor Russia will risk confrontation with the U.S. over Cuba's political future. Cuba's Foreign Minister Bruno Rodríguez continues to frame the situation as an 'imperial siege,' but the operational reality is that the island's government has no realistic path to breaking the oil blockade without a deal.

Senior Pentagon officials told journalists on March 19 that airstrikes targeting narco-trafficking vessels in the Caribbean and Pacific are 'just the beginning' of a broader anti-cartel military campaign. Officials explicitly declined to rule out unilateral ground operations in other countries, according to Infobae's Washington bureau.

The 'Shield of the Americas' coalition — launched at Trump National Doral on March 7 — now includes 17 countries, with Chile as the most recent addition. Ecuador is explicitly cited by the Pentagon as the operational model. The coalition framework gives Washington a legal and political structure through which to argue that operations are 'invited' rather than unilateral, but Petro's Colombia is not a member and has loudly opposed U.S. military presence.

DNI Tulsi Gabbard's 2026 Annual Threat Assessment named ELN and FARC dissidents as a regional threat and described MS-13 cells as active within the United States. The document provides the intelligence community's formal framing for the escalation posture, giving the Pentagon institutional cover for expanded operations.

Brazilian federal authorities launched 'Operación Fuerza Integrada' across 15 states, executing 181 search-and-seizure orders and 112 arrest warrants targeting organized crime networks, according to Prensa Latina. The operation is among the largest coordinated federal law enforcement actions in Brazil this year.

Canada issued a travel advisory upgrade for Brazil, citing rising gang violence in São Paulo, Rio de Janeiro, and Recife — specifically armed robberies, carjackings, and public shootouts. Sweden, the Netherlands, Germany, Italy, Thailand, and France joined similar advisory postures according to Travel and Tour World. The timing, roughly two months before the southern hemisphere winter travel season, will affect tourism revenue projections.

U.S. Special Envoy Richard Grenell — former acting DNI — publicly warned that Nicaragua's mining sector could face targeted sanctions if the Ortega-Murillo government does not reverse the confiscation of a U.S.-owned mining company and the subsequent transfer of its assets to Chinese-linked firms. This is the most direct U.S. threat against Nicaragua's extractive sector in years.

Nicaragua was simultaneously added to a U.S. visa bond list requiring tourists to post up to $15,000 as a condition of entry — a measure framed as addressing migration pressure but which effectively adds another layer of economic isolation to an already-sanctioned government.

Paraguay's legislature ratified the Mercosur-EU trade agreement, making it the final South American nation to do so and clearing the path for the deal's formal entry into force. The agreement — negotiated over more than two decades — opens significant tariff reduction pathways for agricultural exports and creates new European market access for Paraguayan beef, soy, and processed goods.

The ratification comes despite ongoing domestic concerns about corruption and governance. Protests against political corruption have continued sporadically in Asunción.

Chile joined the U.S.-led 'Shield of the Americas' anti-narco coalition as its 17th member, according to Pentagon officials. The move reflects the Boric government's pragmatic security posture despite Chile's generally center-left orientation — driven in part by the growing presence of Venezuelan Tren de Aragua gang members and a sharp increase in kidnappings and murders attributed to foreign criminal networks.

Chile also began physical construction of border barriers on its northern frontier with Peru and Bolivia to reduce irregular migration. The barrier project was a centerpiece of the José Antonio Kast campaign platform in the 2025 elections but was ultimately adopted — at least partially — by the sitting government, illustrating how far Chile's security consensus has shifted rightward.

El País English published a detailed investigation into rampant illegal gold mining along the Nicaragua-Costa Rica border, fueled by Chinese demand. The reporting describes a full spectrum of criminal activity — drug trafficking, weapons smuggling, human trafficking, and reported organ trafficking — operating in the ecological corridor between the two countries.

The story is significant beyond the environmental angle. The criminal infrastructure described is deep, multi-commodity, and cross-border — and it operates in an area with minimal state presence on the Nicaraguan side. The failed 2001 Infinito Gold concession and a 2011 court reversal mean there is no legal extraction framework, leaving the field entirely to illicit operators.
