The President Trump administration just took its border fight straight into the banking system.
On June 5, 2026, the U.S. Department of the Treasury announced that its Financial Crimes Enforcement Network, FinCEN, issued an advisory urging financial institutions to be vigilant against the risks tied to the unlawful employment of illegal aliens.
Translation for the people who pay taxes and follow the rules: the banks are now being told to watch for identity theft, payroll tax fraud, and money laundering connected to off-the-books illegal labor.
Treasury said the advisory is the first step in carrying out Executive Order 14406, Restoring Integrity to America’s Financial System.

Treasury Secretary Scott Bessent did not hide the point of it.
Bessent said President Trump has done more than anyone in history to secure the nation’s borders, and that securing the financial system is part of that same effort.
He added that the administration will not allow illegal aliens to abuse financial institutions to steal billions of dollars from hardworking American taxpayers.
The dollar figures back up the urgency. Treasury said 2025 financial institution reports showed more than $2.5 billion in suspicious activity tied to payroll tax fraud schemes.
One case in the advisory described two foreign national fraudsters running a years-long payroll scheme using undocumented workers that cost the country more than $38 million.
The U.S. Department of the Treasury gave the official breakdown in its announcement:
Today, the U.S. Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN) issued an Advisory urging financial institutions to be vigilant against risks presented by the unlawful employment of illegal aliens.
“President Trump has done more than anyone in history to secure our nation’s borders. Part of that effort includes securing our financial system,” said Secretary of the Treasury Scott Bessent.
“This Administration will not allow illegal aliens to abuse financial institutions to steal billions of dollars from hardworking American taxpayers.”
By hiring, concealing, and exploiting non-work authorized populations, employers can gain an unfair advantage over legitimate U.S. businesses, depress wages, facilitate identity theft of Americans, and steal tax revenue meant for government benefit programs. Schemes to pay unlawful workers often rely upon access to the U.S. financial system, including U.S. banks.
In one case study described in the Advisory, two foreign national fraudsters conspired to operate a years-long payroll scheme that employed undocumented aliens working illegally and cost the United States more than $38 million.
FinCEN issued this Advisory jointly with the Federal Deposit Insurance Corporation, Office of the Comptroller of the Currency, and National Credit Union Administration and in coordination with the Internal Revenue Service. This Advisory supports Executive Order 14406, Restoring Integrity to America’s Financial System, and Treasury’s continued effort to prevent the exploitation of the U.S. financial system by illegal aliens in the United States.
The Advisory calls attention to identity theft and payroll fraud as key features in schemes by complicit employers in the agriculture, construction, domestic service, hospitality, and other industries to conceal violations of U.S. immigration laws.
Complicit employers can also use payroll tax fraud schemes to conceal their hiring of low-wage unlawful alien workers, as well as to evade taxes and workers’ compensation benefits. In 2025, financial institutions reported over $2.5 billion in suspicious activity associated with these payroll tax fraud schemes.
That is the part too many people ignore.
Treasury said the cash skimmed off illegal labor can be leveraged to help finance transnational criminal organizations, several of which have already been designated as Foreign Terrorist Organizations.
Drug trafficking. Human trafficking.
The same cartels Washington spent years pretending were a vague problem.
And the victims are not abstract. Treasury said employers who hire, conceal, and exploit non-work-authorized labor gain an unfair advantage over legitimate American businesses, depress wages, and facilitate identity theft of actual Americans.
They also steal tax revenue meant for government benefit programs, money that was supposed to go to citizens.
FinCEN did not issue this alone. The advisory went out jointly with the FDIC, the OCC, and the NCUA, and in coordination with the IRS.
It includes 18 red-flag indicators and asks banks to use the key term FINANCIALINTEGRITY-2026-A002 on any suspicious activity reports tied to the advisory.
For years the political class treated illegal hiring as a wink-and-nod arrangement that everyone tolerated. This guidance points the financial system’s own detection tools straight at the money behind it.
It is one executive order turning into real enforcement, and the people getting protected are the taxpayers who were footing the bill all along.
