The Cartel Transformation: From Cocaine to Diversification
Prior to 2016, Mexican cartels, largely driven by the lucrative market for cocaine destined for the U.S., operated with a relatively simple business model. However, as U.S. demand began to plateau and law enforcement intensified its efforts, cartels diversified their operations, moving into other illicit goods – including fentanyl, cannabis, and increasingly, cryptocurrency – and expanding their reach into neighboring Central American countries. This diversification, coupled with the rise of organized crime networks in Guatemala, Honduras, and El Salvador, created a more complex and decentralized criminal ecosystem. “The cartels are no longer simply regional players,” explains Dr. Elena Ramirez, a political science professor specializing in transnational crime at the University of California, San Diego. “They’ve effectively created a continental network, exploiting weak governance and economic vulnerabilities across the Americas.”
Recent data from the Department of Homeland Security indicates a significant increase in fentanyl seizures originating in Mexico, rising from approximately 44,000 pounds in 2019 to over 130,000 pounds in 2024. Furthermore, the volume of migrants attempting to cross the Rio Grande – although having seen a slight dip in 2024 – remains substantially higher than pre-2016 levels, largely driven by instability and violence in Central America and the promise of economic opportunity in the United States.
Shifting Alliances and Regional Instability
The 2018 Mexican presidential election, which brought Claudia Sheinbaum to power, represents a pivotal shift in the security landscape. While Sheinbaum has reiterated her commitment to cooperation with the U.S., her administration’s focus on addressing the root causes of migration – poverty, violence, and climate change – alongside its efforts to combat organized crime, reflects a broader change in regional priorities. The rise of the Morena party, which emphasizes social justice and human rights, has created a cautious approach to security cooperation that prioritizes addressing systemic issues rather than solely relying on law enforcement strategies. “Mexico’s approach has moved from reactive suppression to a more proactive, preventative one,” states Marco Gutierrez, a former intelligence analyst specializing in Latin American security. “This requires a fundamental re-evaluation of the U.S.-Mexico security relationship.”
The evolving dynamics in Central America – the growing influence of gangs like MS-13 and Barrio 18, coupled with ongoing political instability and corruption – further complicates the situation. The United States’ withdrawal from Afghanistan, and the subsequent chaos and power vacuum, also created opportunities for transnational criminal organizations to expand their operations throughout the region.
Looking Ahead: A Decade of Uncertainty
Short-term outcomes over the next six months are likely to remain characterized by heightened border security measures, increased fentanyl seizures, and continued migration pressures. However, without a sustained, multilateral effort addressing the root causes of instability throughout the Americas, the situation is likely to deteriorate. Long-term, the U.S.-Mexico security relationship must evolve beyond punitive measures and strategic counter-narcotics campaigns. It demands a collaborative, holistic approach that incorporates economic development, institutional reform, and social justice initiatives.
The challenge is not simply to contain the flow of illicit goods and migrants. It’s to build a truly stable and prosperous hemisphere. This requires a fundamental shift in perspective – recognizing that the security of the United States and Mexico are inextricably linked and that a shared solution demands a shared responsibility.
