Scenarios

Most likely: Persistent fragmentation and managed instability

The most likely scenario for Mexico is one of continued fragmentation and managed instability. On this trajectory, current trends persist without major policy disruption. Criminal organizations remain divided, with splinter groups competing for territorial control in strategic corridors such as border regions, Pacific ports and key logistics hubs inside the country. Violence will remain a prominent feature of the security landscape, though it will be geographically uneven and concentrated where rivals fight for lucrative markets and transit routes.

The Mexican government maintains a hybrid strategy that combines social programs to address root causes with targeted enforcement actions against high-profile criminals. This approach avoids large-scale confrontations while also taking into account the state’s limited ability to dismantle established criminal networks.

In this scenario, the U.S. increases pressure on Mexican authorities while calibrating its actions to avoid a rupture in bilateral relations. There is an expansion of intelligence sharing, especially regarding financial flows and the production of synthetic drugs. Targeted sanctions against individuals and entities linked to cartels become more frequent. Technological tools, such as surveillance drones and cyber capabilities, are used to disrupt operations.

Washington refrains from direct military involvement or unilateral actions within Mexican territory, acknowledging the political sensitivities these measures could stir. The ACCC primarily functions as a coordination platform that enhances information sharing and enables more effective interdiction efforts in transit countries. However, its operational impact within Mexico itself remains limited.

This scenario implies continuity rather than resolution. Mexico avoids systemic destabilization and maintains overall state coherence, yet it fails to regain full territorial control. Criminal groups continue operating with relative impunity in parts of the country, further embedding themselves in local economies.

Bilateral relations with the U.S. remain cooperative, but they occasionally face tensions over the scope and nature of security cooperation. This situation illustrates a balance between two competing factors: Mexico’s hesitance to adopt aggressive enforcement strategies that could spike violence, and America’s aim to address cross-border effects of cartel activity without undermining a vital partner.

Somewhat likely: U.S.-driven escalation and cartel consolidation

A somewhat likely scenario involves escalation driven by a more assertive U.S. posture, potentially producing unintended consequences in Mexico. This could occur if domestic political pressure over fentanyl deaths pushes Washington toward forceful measures, including designating major Mexican cartels as terrorist organizations.

Financial warfare would intensify, targeting not only cartel leaders but also the broader networks that facilitate money laundering and logistical support. Cyber operations and intelligence-driven strikes would aim to disrupt production and distribution chains. In extreme cases, the U.S. might consider limited unilateral actions on national security grounds.

Such a shift would have profound implications for cartel dynamics within Mexico. Faced with increased external pressure, fragmented groups could consolidate into larger, more cohesive blocs to enhance their resilience. This process of consolidation would likely be accompanied by intensified violence, as groups compete to control strategic assets and eliminate rivals.

At the same time, cartels could adopt more aggressive tactics, including attacks on infrastructure, security forces or perceived collaborators to deter external intervention. The resulting environment could resemble a higher-intensity conflict, with specific areas experiencing conditions similar to insurgency.

Mexico’s political response to this scenario would be shaped by concerns over sovereignty. Increased U.S. involvement, particularly if perceived as unilateral, would generate domestic backlash and complicate cooperation between the two governments. While certain forms of collaboration might continue, trust would erode, limiting the effectiveness of joint efforts.

The ACCC could take a more active role by facilitating coordinated efforts across multiple countries to disrupt trafficking routes that extend beyond Mexico’s borders. However, Mexico’s involvement may be limited by political factors, potentially hindering the coalition’s effectiveness in operating within its territory.

The short-term effects of this escalation scenario could involve disruptions to cartel operations and the removal of key leadership figures. But these gains would likely be counterbalanced by increased violence and instability. In the long term, stronger and more centralized criminal organizations might emerge, better equipped to withstand external pressures. This outcome would complicate future law enforcement efforts and could lead to a more dangerous security environment.

While this scenario is less likely than the continuation of managed instability, it remains plausible given the evolving political dynamics in the U.S. and the growing emphasis on treating cartels as national security threats.

Least likely: Stabilization through institutional reform

The least likely scenario involves a gradual stabilization of Mexico’s security environment through institutional strengthening and an effective partnership between the two countries. Achieving this would require a long-term commitment from Mexican authorities to reform local law enforcement and judicial systems, reduce corruption and improve state presence in contested regions.

Economic development initiatives would need to provide viable alternatives to illicit activities, particularly in regions where criminal organizations currently dominate local economies. Such reforms would not produce immediate results but could, over time, reduce the structural conditions that enable cartel power.

In this scenario, the U.S. adopts a balanced approach that prioritizes capacity-building and long-term cooperation over short-term disruption. Investments in institutional development, combined with continued efforts to target financial networks, would complement Mexican reforms.

Expanded legal pathways for trade and migration could reduce the incentives that drive illicit activity, while coordinated enforcement efforts would focus on dismantling the economic foundations of organized crime rather than relying primarily on kinetic operations. The ACCC would play a central role in this framework, enabling seamless intelligence-sharing, harmonizing legal approaches and coordinating financial enforcement across the region.

As institutional capacity improves, criminal organizations would face greater constraints on their operations. Rather than resorting to overt violence, they might shift toward less visible activities or relocate portions of their operations elsewhere. This would contribute to a gradual decline in homicide rates and a reduction in territorial disputes.

Improved rule of law would bolster investor confidence and foster broader economic growth, reinforcing a positive cycle of stabilization. The bilateral relationship between Mexico and the U.S. would deepen, evolving into a more integrated security partnership.

Despite its potential benefits, this scenario remains the least likely due to the scale of the reforms required and the entrenched interests that resist change. Institutional transformation at the local level is a complex and long-term process, and political incentives often favor short-term solutions over sustained investment in governance.

Achieving such alignment on a security strategy between Mexico and the U.S. would require addressing longstanding sensitivities and differing policy priorities. While some aspects of this scenario may gradually come to fruition, it is improbable that a comprehensive agreement will be reached within the next decade.

In comparative terms, the three scenarios highlight the central trade-offs facing policymakers. Persistent fragmentation offers stability without resolution, allowing both Mexico and the U.S. to manage the problem without fundamentally altering its underlying dynamics.

Escalation promises more decisive action but carries significant risks of backlash and unintended consequences, potentially worsening the security environment it seeks to improve. Gradual stabilization provides the most favorable long-term outcome but demands a level of political will and institutional capacity that is currently lacking.

Ultimately, Mexico’s security future will be shaped by the interplay of domestic constraints and external pressures. The most likely outcome is a continuation of managed instability, in which neither the state nor criminal organizations achieve decisive dominance.

Changes in U.S. policy or shifts in Mexico’s internal approach could alter the situation, leading to either increased conflict or gradual stabilization. The formation of initiatives such as the Americas Counter Cartel Coalition highlights a growing awareness that cartel-related challenges are inherently transnational. Whether this awareness leads to effective, balanced action will ultimately determine which scenario prevails.
