In one of the most expansive financial enforcement actions in recent years, the U.S. Department of the Treasury has launched a multi-tiered operation targeting more than 100 money services businesses (MSBs) operating along the country’s southwest border, signaling a renewed push by the Trump administration to choke off illicit financial flows tied to cartels, drug trafficking, and human smuggling.
The operation, announced by the Treasury’s Financial Crimes Enforcement Network (FinCEN), has already resulted in six formal notices of investigation, dozens of referrals to the Internal Revenue Service for examination, and more than 50 compliance outreach letters to businesses suspected of falling short of federal anti-money laundering requirements. Treasury officials say the effort is far from over and could lead to civil penalties, injunctions, and criminal referrals as investigators continue to analyze the data.
Money services businesses — which include currency exchangers, money transmitters, check cashers, and other non-bank financial providers — play a critical role in facilitating everyday transactions, particularly in border communities and immigrant populations. But regulators have long warned that these firms also face heightened exposure to illicit finance due to the volume of cash movement, cross-border transactions, and informal payment channels they support.
“At President Trump’s direction, the Treasury Department is utilizing all tools to stop terrorist cartels, drug traffickers, and human smugglers,” Treasury Secretary Scott Bessent said in a statement accompanying the announcement. “This sweeping operation will help root out potential cartel-related money laundering from the U.S. financial system.”
A Data-Driven Enforcement Campaign
What sets this operation apart, officials say, is its scale and reliance on advanced data analytics. FinCEN’s review drew on more than one million Currency Transaction Reports and approximately 87,000 Suspicious Activity Reports — mandatory filings submitted by financial institutions to flag large cash transactions or potentially illicit behavior. Using high-performance computing and advanced processing techniques, analysts identified patterns and vulnerabilities that pointed to possible non-compliance with the Bank Secrecy Act, the cornerstone U.S. law governing anti-money laundering controls.
Treasury described the initiative as the first of its kind — a large-scale, technology-driven enforcement campaign designed to convert fragmented financial data into “decision-grade leads” for regulators and law enforcement. The agency says this modernization effort allows it to uncover networks of suspicious activity more quickly and efficiently than traditional manual reviews.
The operation is being coordinated with the Homeland Security Task Force, the Internal Revenue Service, and federal and state law enforcement partners, reflecting a whole-of-government approach to financial crime enforcement at the border.
Border Security Meets Financial Regulation
The crackdown aligns with the administration’s broader push to strengthen border security and dismantle transnational criminal organizations. Officials argue that disrupting money flows is as critical as intercepting drugs or migrants, since cartels and smuggling networks depend on the ability to move and launder proceeds through legitimate-looking financial channels.
According to Treasury, MSBs operating near the southwest border face elevated risks linked to proceeds from narcotics trafficking, human smuggling, and other organized criminal activities. When compliance controls weaken — or fail altogether — authorities say criminal groups gain opportunities to embed illicit funds into the U.S. financial system.
FinCEN officials emphasized that the current actions are tiered, meaning that not all businesses face the same level of scrutiny or enforcement. Some firms have received outreach letters aimed at correcting compliance gaps, while others are under formal investigation or being referred for tax and regulatory examinations. Still, Treasury made clear that willful violations of the Bank Secrecy Act will not be tolerated.
Potential Penalties and Ongoing Investigations
As the investigation continues, Treasury may impose civil monetary penalties, seek court-ordered injunctions, issue formal warning letters, or refer cases for criminal prosecution. Regulators stressed that enforcement decisions will follow the facts uncovered during examinations and data analysis.
The agency framed the operation not only as a punitive measure but also as a signal to the broader MSB sector that compliance expectations are tightening, particularly in high-risk geographic areas. Businesses that fail to correct deficiencies could face escalating enforcement actions.
Compliance Expectations for MSBs
Treasury reiterated that all money services businesses must maintain robust, risk-based anti-money laundering and counter-terrorist financing programs. This includes verifying customer identities when required, monitoring transactions for suspicious behavior, filing timely Suspicious Activity Reports, submitting Currency Transaction Reports for large cash transactions, and maintaining oversight of agents, branches, and third-party partners.
Officials warned that lapses in these controls undermine national security by depriving law enforcement agencies of critical financial intelligence and increasing the risk that criminal networks exploit legitimate businesses as conduits for illicit funds.
A Signal to the Financial Sector
For the broader financial and compliance community, the operation sends a clear message: data analytics and regulatory technology are becoming central tools in enforcement strategy, and regulators are increasingly capable of detecting patterns across massive datasets. As Treasury continues to modernize its technology infrastructure, similar large-scale enforcement initiatives may follow in other high-risk sectors.
The campaign also highlights the expanding intersection between border security, financial regulation, and national security policy — an area likely to remain a focal point for regulators and compliance professionals alike.
As FinCEN continues to follow the data trail, the ultimate impact of the operation may reshape how money services businesses assess risk, invest in compliance infrastructure, and engage with regulators in one of the most scrutinized financial corridors in the United States.
