The U.S. Treasury Department has identified nearly $5 billion in bank and other financial transactions linked to suspected human smuggling operations, a sum that came alongside a striking 62% drop in suspicious activity reports filed in 2025 compared with the year before. The findings, drawn from a forthcoming report examining 67,540 Bank Secrecy Act filings, trace everything from cash smuggled across the southwestern border to a chartered flight that carried Indian nationals from Egypt to Jamaica through the United Arab Emirates and onward to Nicaragua.
According to the New York Post, the Financial Crimes Enforcement Network found $4.9 billion in suspicious exchanges by combing through Bank Secrecy Act data, with suspicious transaction reports peaking at 29,266 in 2024 before falling sharply to 11,018 filings in 2025. Flagged payments tied to charter flights believed connected to human smuggling totaled more than $3 million, the outlet reported, part of a pattern of migrants attempting to enter the United States by land as well as by air.
The transactions examined showed telltale signs investigators associate with smuggling networks: inconsistent payment amounts, unexplained refunds, contracts that did not match the actual movement of money, and no verifiable familial connection between the people sending and receiving funds. Suspicious activity also included transfers along common migration routes, excessive cash activity along the southwestern border, and unverifiable relationships between originators and beneficiaries, per the report cited by the Post.
Where the Money and the Reports Originated
The United States hosted the greatest number of suspicious transactions overall, with California and Texas generating the most reports domestically. Internationally, suspicious transaction reports also originated from Mexico, Guatemala, Honduras, and Colombia, reflecting the cross-border nature of the financial pipelines feeding smuggling operations.
FinCEN Director Andrea Gacki said many human smuggling networks generate profit for larger transnational criminal organizations, including Mexico-based drug cartels, according to the Post's reporting. Gacki added that financial-institution reports of suspicious activity provide critical information for investigators trying to untangle those networks.
The dossier behind the Treasury's findings also draws a sharp line between people smuggling — the unlawful transportation of unauthorized persons inside the United States — and human trafficking, which involves the recruitment, coercion, or transportation of a person into forced labor or commercial sex acts. The report frames the two as related but legally distinct categories of criminal activity.
Banks Handle the Big Dollars, Money Transfer Firms Handle the Volume
Roughly 3% of the flagged transactions were associated with traditional banks, yet those institutions accounted for around $3 billion, or 61%, of the money flagged in Bank Secrecy Act data. According to FinCEN, depository institutions flagging human smuggling identified specific typologies including cash structuring, so-called funnel accounts that receive deposits from numerous individuals across diverse locations, and travel agencies — some sham storefronts, others legitimate firms unwittingly facilitating migrant transport.```
Money Services Businesses, by contrast, accounted for at least 97% of the transactions but tend to process lower individual dollar amounts. FinCEN's research notes that suspected smuggling transactions handled by these firms frequently involved transfers outside a customer's usual financial pattern, money sent along common migration corridors, and structured payments designed to evade Bank Secrecy Act recordkeeping requirements. The regulatory gap matters: Money Services Businesses must file a Suspicious Activity Report for transactions of $2,000 or more when illicit activity is suspected, while traditional depository institutions operate under a $5,000 threshold, according to the Federal Register.
Federal Crackdown Extends Beyond the Numbers
The Treasury's financial trend analysis lands amid a broader federal push to choke off smuggling networks' money supply. In March, FinCEN issued an expanded Geographic Targeting Order requiring money services businesses across 12 border counties in Texas, Arizona, New Mexico, and designated California ZIP codes to report and retain records on cash transactions between $1,000 and $10,000, according to the American Bankers Association's Banking Journal.
Not every enforcement effort has held up in court. Last month, the Ninth Circuit Court of Appeals affirmed a lower-court injunction blocking enforcement of a low-threshold FinCEN cash-reporting order in San Diego ZIP codes, siding with a local check-cashing owner who argued the rule imposed crushing administrative burdens on everyday storefronts, as Ninth Circuit clips FinCEN's border order detailed.
In November 2025, FinCEN issued Alert FIN-2025-Alert003 urging financial institutions and wire services to heighten scrutiny on cross-border money transfers involving non-citizens without legal status, citing Executive Order 14159 to curb the movement of illicitly obtained funds. And in June, FinCEN and federal banking regulators issued a joint advisory under Executive Order 14406 establishing red flags for banks to identify illicit activity connected to unlawful employment of non-work-authorized populations and payroll tax fraud, according to a summary from Ashurst Perkins Coie.
The financial monitoring runs parallel to criminal prosecution efforts. The Department of Justice expanded Joint Task Force Alpha, a specialized human smuggling prosecution unit formed in 2021, to northern and maritime border districts in September 2025, resulting in more than 470 arrests of cartel human smuggling leaders and facilitators by mid-2026, per the Department of Justice. FinCEN had earlier rolled out its COMMAND program in Texas border cities including McAllen and El Paso to train community and regional financial institutions to spot cartel financial infrastructure, an effort Hoodline detailed in its report on the program's launch.
Treasury officials say the department will continue working with the private sector and law enforcement to dismantle human smuggling networks and protect U.S. borders. The Post's report also noted that many of the migrants captured in these financial trails entered the country by illegally crossing the Mexico border under former President Joe Biden, with many later released into the American interior after being encountered at the frontier — a population the outlet put at more than 8 million people. Treasury Secretary Scott Bessent has overseen the department's enforcement posture during this period, while Gacki has continued to brief lawmakers on the scope of the financial data underpinning the findings.
