The Financial Crimes Enforcement Network, or FinCEN, has identified billions in suspicious financial transactions. It is suspected the transactions were connected to human smuggling according to a new Treasury Department analysis.

The findings highlight how financial institutions can provide investigators with a window into the operations of smuggling networks and other transnational criminal organizations.

The Justice Department has noted that trafficking can occur in industries ranging from agriculture and factories to restaurants, hotels, domestic work and commercial sex.

FinCEN analyzed 67,540 Bank Secrecy Act reports covering the three-year period, identifying approximately $4.9 billion in suspicious activity.

The transactions included large amounts of cash activity near the U.S.-Mexico border, transfers along established migration routes, and payments involving parties whose relationships could not be verified.

What Is FinCEN?

The Financial Crimes Enforcement Network is a bureau of the U.S. Department of the Treasury responsible for safeguarding the financial system from money laundering, terrorist financing and other financial crimes.

FinCEN works closely with banks, money services businesses and other financial institutions that are required to report certain suspicious financial activity. Those reports can help federal law enforcement identify patterns that might otherwise remain hidden.

The Bank Secrecy Act is particularly important to that effort. Financial institutions file suspicious activity reports, known as SARs, when transactions or patterns raise concerns about potential criminal activity.

FinCEN then analyzes that information and shares financial intelligence with law enforcement and other government agencies.

The agency's work extends beyond immigration-related crimes. FinCEN has also identified financial networks associated with drug cartels, fraud, money laundering and other forms of organized criminal activity.

Nearly $5 Billion in Suspicious Transactions

The new analysis found that the suspicious transactions associated with suspected human smuggling totaled approximately $4.9 billion.  And took place from Jan. 1, 2023, through Dec. 31, 2025.

The largest concentration involved cash activity along the southwestern U.S. border. Other transactions followed common migration routes between the United States, Mexico, Central America, and other countries.

Some transactions involved large payments for charter flights. One reported pattern involved a charter flight carrying Indian nationals from Egypt to Jamaica through the United Arab Emirates and Nicaragua. That route was believed by investigators to be used to facilitate attempts to enter the United States over land.

FinCEN's analysis also found that 97% of the suspicious activity reports involved money services businesses, while about 3% involved banks. However, traditional banks accounted for roughly $3 billion, or 61%, of the suspicious dollar amount identified in the reports.

The report indicates that 59% of the funds showed no verifiable familial connection between the parties involved in the transactions.

FinCEN Claims Suspicious Reports Declined in 2025

The number of suspicious activity reports connected to suspected smuggling fell sharply in 2025.

FinCEN identified 29,266 suspicious transactions in 2024, compared with 11,018 reports in 2025, according to the analysis. That represented a decline of about 62%.

The drop occurred as federal authorities increased scrutiny of suspected smuggling networks and expanded enforcement efforts.

The timing also coincided with preparations for the 2026 FIFA World Cup, which brought heightened attention to trafficking and smuggling risks in the United States.

Federal agencies have announced enforcement operations aimed at identifying trafficking networks and protecting potential victims ahead of the tournament.

California and Texas generated the largest number of reports in the United States, according to the analysis. Mexico, Guatemala, Honduras and Colombia also appeared prominently in the financial activity examined.

Human Smuggling Is Different than Human Trafficking

The terms human smuggling and human trafficking are sometimes used interchangeably, but they describe different crimes under U.S. law.

Human smuggling generally involves helping a person unlawfully enter or remain in a country, often in exchange for payment. Human trafficking, by contrast, involves exploitation. Federal law defines trafficking as compelling or coercing someone to provide labor or services or to engage in commercial sex acts.

Trafficking does not necessarily require a person to cross an international border. A U.S. citizen can be a trafficking victim, and trafficking can occur entirely within the United States.

The two crimes can overlap. A person who initially pays a smuggler to enter the country illegally can later become a victim of trafficking if criminals use force, fraud, coercion or other methods to exploit that person.

Human Trafficking Remains Difficult to Measure

Obtaining an accurate nationwide count of human trafficking victims is difficult because the crime frequently goes undetected.

A 2026 Government Accountability Office report said the National Human Trafficking Hotline identified nearly 12,000 trafficking cases involving nearly 22,000 potential victims in 2024. The GAO cautioned that these figures do not represent the full scope of trafficking because many cases are never reported or identified.

Federal prosecutors also continue to pursue cases involving criminal organizations accused of combining smuggling, trafficking and money laundering.

In June 2026, federal prosecutors in New York charged two Uzbek nationals with alien smuggling and money laundering. The Justice Department said such operations can also involve exploitation, drug trafficking and sexual abuse.

FinCEN Continues to Follow the Money

FinCEN's findings underscore the importance of financial records in combating criminal networks.

Large cash deposits, unusual transfers, unexplained refunds, inconsistent payment amounts and questionable business relationships can create financial trails that investigators can examine.

In some cases, those records may connect seemingly unrelated transactions and help authorities identify the people and organizations operating behind a smuggling network.

FinCEN Director Andrea Gacki has emphasized that suspicious activity reports from financial institutions can provide critical information to law enforcement.

The findings also demonstrate the scale of money moving through networks suspected of facilitating unlawful migration.

While a suspicious transaction is not itself proof that a crime occurred, financial intelligence can provide investigators with leads that can be combined with other evidence.

As federal agencies continue targeting transnational criminal organizations, financial data is expected to remain an important component of investigations into human smuggling, human trafficking and money laundering.
