Border 2025. Smart Shield or Economic Chaos?

The challenge is double and simultaneous: reducing cross-border crime while sustaining North America’s largest trade corridor. In 2024, trade between Mexico and the United States reached $839.6 billion, while Laredo—its prime node—processed tens of thousands of truck crossings per day, accounting for $331 billion in annual trade at that single port. Any policy that slows legal crossings translates directly into costs for jobs, prices, and trust. Discussing border security infrastructure is, in fact, discussing industrial and logistical policy at a binational scale.

On the operational front, 2024 marked a turning point. Following the June 4th presidential proclamation, “encounters” dropped by 29% from May to June, and the seven-day moving average fell by over 50% by the end of the month. This was the lowest monthly level since January 2021. The message is clear: tougher executive rules can modify flows in the short term, but they require a technological and managerial framework to sustain them without paralyzing legal crossings.

That framework is under construction. Congress and the Department of Homeland Security (DHS) have pushed a technological leap with autonomous surveillance towers (AST), the integrated tower program (IST), and “common operating picture” platforms. By 2025, legislators explicitly recognized AST as force multipliers and allocated funds for expansion, with budget requests targeting hundreds of towers by 2026. The policy signal is unambiguous: permanent sensors and real-time analytics to cover gaps between ports of entry.

But the less glamorous side of the border lies at the ports of entry. A 2025 DHS Inspector General audit found that of 150 fixed non-intrusive inspection (NII) systems purchased between 2020 and 2024, only 33% had been installed by the review date, and 46% of installed equipment had prolonged outages. In other words, billions were spent on “scanners” that still fall short of full potential. Since most fentanyl is seized at ports or checkpoints, the equation is obvious: more and better NII means real security without halting commerce.

The drug trade explains the urgency. In FY2024, CBP seized over 19,600 pounds of fentanyl (through August), a historic peak; between 2018 and 2024, over 92% of fentanyl was seized at ports of entry or checkpoints. This statistic dismantles myths and refocuses priorities: the heart of containment lies in the ports, where technology, intelligence, and risk profiling work best.

On the Mexican side, 2025 opened with a geopolitical twist: to avoid a tariff clash, President Claudia Sheinbaum agreed to deploy 10,000 personnel to the northern border and coordinate fentanyl enforcement while Washington pledged to stem weapons trafficking into Mexico. The deployment, concentrated in key municipalities, linked security and trade in an unprecedented way in the T-MEC era. The question now is its sustainability, both fiscally and operationally, in a year of tight budgets and multiple domestic security fronts.

Mexico is also modernizing its customs infrastructure: next-generation NII systems, mobile labs, and expanded scanning for cargo and passengers. Yet seizure trends show mixed results. Between 2019 and 2024, hundreds of clandestine labs were dismantled, but in 2024 fentanyl seizures fell compared to 2023, forcing authorities to refine metrics and strengthen chain-of-custody. In short: there is investment and deployment, but Mexico needs greater traceability and harmonized measurement across agencies to avoid under- or over-reporting.

So what did 2024 teach us in percentages, and where should 2025 adjust? First, stricter rules temporarily reduced irregular crossings (–29% from May to June; >–50% on weekly averages), but their effectiveness depends on sustaining deep inspections where most seizures occur. Second, combating fentanyl means prioritizing ports of entry, where evidence shows the overwhelming majority of illicit flow is captured. Third, the expansion of AST/IST between ports must be paired with interoperable data-sharing with Mexican customs and stronger south-to-north weapons controls. Fourth, the border is not a line: it is a logistical ecosystem where one extra second per truck multiplies by thousands of daily crossings, with measurable impacts on inflation and productivity.

The challenges for 2025 are as political as they are technical. In the U.S., ongoing court battles over immigration and deportation measures create operational uncertainty; in Mexico, the militarized northern deployment must coexist with internal security priorities and the civilian professionalization of customs. On the U.S. side, closing the gaps flagged by the OIG in NII deployment and maintenance is urgent; on the Mexican side, consolidating modernization with public indicators and cross-audits will raise bilateral trust. If both countries align rules, sensors, and data—and measure success with shared indicators (crossing times, % of cargo scanned, seizures by modality, repair times for NII)—the border can become safer and faster at once. That is the smart shield that an $840 billion economy demands, without rhetorical shortcuts or hidden costs.
