CNBV decrees temporary management intervention of CI Banco and Intercam Banco following US FinCEN money-laundering designation

Mechanism

FinCEN's 25 June 2025 orders under Section 2313a of the FY2024 NDAA (added by the FEND Off Fentanyl Act) named CI Banco, Intercam Banco, and Vector Casa de Bolsa as foreign financial institutions of primary money-laundering concern, citing links to the Beltrán-Leyva Cartel, CJNG, and the Gulf Cartel, and barred certain US-dollar fund transmittals to and from them. Within 24 hours Mexico's own banking regulator moved pre-emptively: the CNBV Governing Board, acting under Article 129 of the Ley de Instituciones de Crédito, replaced the administrative bodies and legal representatives of CI Banco and Intercam Banco with CNBV-appointed management, while leaving day-to-day operations running. The stated purpose was to protect depositors and creditors from any destabilisation stemming from the US designation — not an admission of the underlying money-laundering allegations, which CI Banco and Intercam Banco have publicly disputed. Vector Casa de Bolsa, the third US-designated entity, was not placed under CNBV intervention in this communiqué.

Downstream implications

• First test of Mexico's Article 129 intervention power triggered directly

by a foreign (US) sanctions-adjacent designation rather than a domestic solvency event — a template for how Mexican regulators respond when a US FinCEN/OFAC action threatens a domestically chartered bank's ability to operate.

• CI Banco is a significant trust (fideicomiso) administrator for foreign

investors and cross-border structures in Mexico; a prolonged intervention has knock-on liquidity/administrative risk for clients relying on it as trustee, separate from retail deposit exposure.

• Sets precedent for how far Mexico will go to ring-fence US-designated

institutions rather than contest the FinCEN finding directly.

Open questions

• Duration and exit path of the temporary intervention (no end date

specified in the communiqué).

• Whether Vector Casa de Bolsa faces a parallel intervention from Mexico's

securities regulator (CNBV oversees brokerages too) despite being excluded from this particular decree.

• Ultimate disposition of CI Banco's trust (fideicomiso) book if the

intervention leads to forced sale or wind-down.
