Treasury unleashes sweeping crackdown on money services businesses along southern border, targeting potential cartel money laundering operations that may have funneled millions into the U.S. financial system.
In a major enforcement action, the Financial Crimes Enforcement Network (FinCEN) has launched a multi-tiered operation targeting more than 100 U.S. money services businesses (MSBs) along the southwest border suspected of non-compliance with anti-money laundering regulations. The operation has already resulted in six notices of investigation, dozens of IRS examination referrals, and over 50 compliance outreach letters, according to a statement from the agency.
“At President Trump’s direction, the Treasury Department is utilizing all tools to stop terrorist cartels, drug traffickers, and human smugglers,” said Secretary of the Treasury Scott Bessent. “This sweeping operation will help root out potential cartel-related money laundering from the U.S. financial system.”
Data-Driven Investigation Targets Border Financial Activity
The initiative isn’t a shot in the dark. It’s built on meticulous analysis of over one million Currency Transaction Reports and 87,000 Suspicious Activity Reports submitted by financial institutions, making it one of the most data-intensive operations in FinCEN’s recent history.
What’s driving this heightened scrutiny? Investigations by the U.S. Treasury have uncovered that several Mexican financial institutions, including CIBanco, Intercam, and Vector, allegedly facilitated transfers to U.S. banks and laundered money for notorious cartels including the Jalisco New Generation Cartel (CJNG), Beltrán Leyva Organization, and Gulf Cartel. Perhaps most alarming, CIBanco reportedly processed over $2.1 million for fentanyl precursor chemicals from China.
This isn’t the first time Treasury has turned its attention to the border region. In November 2025, FinCEN and the Office of Foreign Assets Control (OFAC) targeted numerous Mexican gambling establishments linked to Sinaloa Cartel money laundering, working in coordination with Mexican authorities who had already blocked 13 casinos, according to reports.
Geographic Targeting Orders Lower Reporting Thresholds
How do cartels move money across the border? Often through seemingly legitimate businesses that fly under the radar by keeping transactions below typical reporting thresholds. To counter this tactic, FinCEN has issued a Geographic Targeting Order (GTO) requiring MSBs in specific southwest border counties and ZIP codes across Arizona, California, and Texas to file Currency Transaction Reports.
The crackdown intensified in March 2025 when FinCEN targeted 30 ZIP codes across California and Texas near the southwest border, requiring businesses to file CTRs at a dramatically lower $200 threshold. By June, the agency had identified three Mexico-based institutions as primary money laundering concerns, effectively prohibiting U.S. transactions with these entities.
More recently, the agency reissued a modified GTO requiring certain MSBs to file Currency Transaction Reports for cash transactions between $1,000 and $10,000 in targeted southwest border locations — far below the standard $10,000 reporting threshold that applies to most financial institutions.
The message from Treasury is clear: the administration is determined to disrupt the financial pipelines that allow criminal organizations to profit from drug trafficking, human smuggling, and other illicit activities along the U.S.-Mexico border. For MSBs operating in these regions, compliance with anti-money laundering regulations is no longer optional — it’s under the microscope.
