Mexico's National Banking and Securities Commission — the Comisión Nacional Bancaria y de Valores, or CNBV — decreed the temporary administrative intervention of two Mexican banks, CIBanco and Intercam Banco, on 26 June 2025. The intervention was enacted under Article 129 of Mexico's Banking Law and was coordinated with enforcement orders issued by the United States Financial Crimes Enforcement Network, known as FinCEN, against the same institutions for anti-money laundering violations.
The Instituto para la Protección al Ahorro Bancario, Mexico's deposit protection agency, published the administrative appointments in the country's official gazette, the Diario Oficial de la Federación, formalising the transfer of administrative control of the two banks pending resolution of the regulatory proceedings. The CNBV subsequently moved to revoke CIBanco's banking licence following the intervention.
COORDINATED US-MEXICO ENFORCEMENT ACTION
The simultaneous deployment of regulatory tools by both the Mexican and US authorities marks one of the more significant bilateral enforcement actions involving the Mexican banking sector in recent years. FinCEN's involvement reflects the cross-border nature of the alleged anti-money laundering failures, with the United States regulator having jurisdiction over financial institutions that process dollar transactions or maintain correspondent banking relationships with US entities. Both CIBanco and Intercam Banco have had exposure to US dollar flows given the depth of financial integration between the two neighbouring economies.
Correspondent banking relationships are a critical channel through which Mexican banks access the US financial system for trade finance, remittances and international payments. When a Mexican bank is designated by FinCEN for AML deficiencies, its ability to maintain those correspondent relationships is placed at serious risk, effectively limiting or severing its access to dollar liquidity and international payment infrastructure. This dynamic makes a FinCEN designation functionally as consequential for a bank's operations as the domestic regulatory action itself.
The CNBV's use of Article 129 of the Banking Law provides a legal mechanism for placing an institution under the direct administrative control of a government-appointed manager, displacing the bank's board and executives while the situation is assessed and resolved. This tool is designed to protect depositors and maintain financial stability by ensuring the institution continues to function under controlled conditions rather than collapsing in a disorderly manner.
LICENCE REVOCATION AND MARKET IMPLICATIONS
The revocation of CIBanco's banking licence represents the most severe outcome in the Mexican bank regulatory toolkit, effectively ending the institution's authorisation to operate as a deposit-taking bank. Depositors are protected by the IPAB guarantee scheme, which covers balances up to the applicable limit, and the agency's involvement in publishing the administrative appointments signals that it is managing the orderly disposition of the institution.
Intercam Banco's situation remained subject to the ongoing administrative intervention at the time of the CNBV's actions, with the outcome for that institution still to be determined. The regulatory authorities indicated that the intervention framework was designed to assess the financial position of the institution and determine the appropriate path forward, whether through remediation, transfer of operations, or further action.
The episode highlights the increasing willingness of Mexican financial regulators to act forcefully in response to AML compliance failures, particularly when those failures have drawn the attention of US counterparts. For the broader Mexican banking sector, the coordinated intervention serves as a clear signal that cross-border compliance shortcomings will attract a robust regulatory response from both sides of the border.
