Trump's border success takes bite out of cartels' income

The Treasury Department's analysis, released this week, quantifies what border hawks have long intuited: human smuggling generates somewhere between $13 billion and $20 billion annually for Mexican cartels, with the Sinaloa Cartel and CJNG (Jalisco New Generation Cartel) capturing the lion's share. That revenue stream doesn't just pay foot soldiers—it funds weapons acquisition, corruption networks, and the cartel infrastructure that destabilizes entire regions. The numbers matter because they're not abstract: every migrant crossing the southern border under cartel guidance generates between $3,000 and $8,000 in fees, and the cartels move roughly 1.5 million people annually during non-enforcement periods. Trump's enforcement surge—including the restoration of Remain in Mexico policies, increased ICE deportations, and the Title 42 expulsion authority—has compressed migrant flows from a peak of 249,414 encounters in December 2023 to substantially lower monthly rates. Less throughput directly equals less revenue.

The cartel income hit is significant because it creates a secondary effect on the criminal enterprise's operational capacity. Unlike drug smuggling, which can continue through sophisticated tunnel networks and corrupted official channels, human smuggling requires massive logistical networks—safe houses, transportation, guides, and payoffs to corrupt Mexican police and officials. When fewer migrants attempt crossings, fewer of those payroll positions get funded. The Sinaloa Cartel in particular has relied on human smuggling to maintain control of border territory and fund its broader criminal operations. Some analysts argue this revenue pressure may drive cartels toward consolidation or increased violence as they compete for a shrinking pie—a risk factor to monitor.

For the specific people involved, the calculus is immediate and brutal. Coyotes—individual smugglers operating below cartel level—have reported reduced demand and lower fees in field reporting from Texas border towns. Migration to the southern border from Central America has slowed measurably, driven both by enforcement pressure and by word-of-mouth about reduced crossing success rates. The Treasury analysis doesn't sentimentalize this: fewer migrants attempting crossings also means fewer deaths in the desert, fewer drownings in the Rio Grande, and fewer trafficking victims delivered to debt bondage in the U.S. interior.

The conservative read here is straightforward: this is enforcement working exactly as designed. For decades, immigration hardliners argued that lax border policy didn't just create a humanitarian problem—it actively enriched criminal organizations that destabilized Mexico and fueled broader regional crime. They were correct on the mechanism. The Treasury report validates the core argument: tighten enforcement, reduce cartel revenue, reduce incentive for people to attempt dangerous crossings. There's no equivocation needed. The policy works. The argument that enforcement is "cruel" or ineffective takes a harder hit when the data shows it simultaneously reduces cartel profits and migrant deaths from crossing attempts.

What matters next is sustainability and spillover effects. Trump has executive authority to maintain these enforcement levels without congressional action, but Congress will need to reauthorize funding for CBP and ICE operations in upcoming appropriations cycles—likely in spring 2025. Watch for cartel response: Treasury's analysis assumes cartels will attempt to adapt, potentially shifting toward drug smuggling intensity or exploiting alternative routes through ports of entry. The Mexican government's cooperation on enforcement—especially under López Obrador's successor, Claudia Sheinbaum, who took office in October 2024—will determine whether the cartel income pressure actually sticks or whether organized crime simply finds alternative revenue streams.
