CIBanco files lawsuit against the U.S. Treasury Department.

MEXICO CITY.- After being accused of facilitating operations linked to opioid trafficking and being excluded from the U.S. financial system, CIBanco filed a lawsuit in the District of Columbia Court against the U.S. Department of the Treasury and its Financial Crimes Enforcement Network (FinCEN) .

In a 37-page document, he argued that the measure amounts to an "institutional death penalty," prohibiting any transfer of funds to U.S. financial institutions starting September 4, 2025.

They point out that the decision was made without prior notice or opportunity for defense.

The Mexican financial firm said that "CIBanco faces an institutional death sentence based on accusations so lacking in specificity that they are nonexistent."

It also cites the order as violating the Administrative Procedures Act and due process under the U.S. Constitution.

The Treasury's decision puts at risk more than $40 billion in U.S. interest-based assets managed by CIBanco through trusts.

Including pension funds, investments and properties of citizens and companies of that country, according to the lawsuit.

CIBanco's lawsuit details that "in summary, FinCEN's publication of the Final Order violates the requirements of the Administrative Procedures Act, as well as due process under the United States Constitution."

“Without immediate correction, this illegal order puts the Bank at risk of insolvency and collapse .”

The bank stated that the measure has already caused the loss of all its correspondents in the United States, paralyzing foreign exchange operations and international transfers that represented more than half of its income.

In addition, Visa canceled its contract, rendering approximately 220,000 debit and prepaid cards issued by the institution unusable.

The bank's defense argued that FinCEN 's accusations are based on alleged transactions with companies in Mexico and China , but without names, dates or verifiable details.

The document states that "CIBanco has desperately sought to identify which customers and transactions FinCEN is referring to, but it's like looking for needles in hayfields."

The financial institution warned that the sanction threatens its imminent liquidation and the loss of more than 3,000 jobs.

He also warned that the forced relocation of his $400 million trust division could directly affect beneficiaries in both the United States and Mexico.
