Three Mexican financial institutions will be barred from transacting with U.S.-based banks after a U.S. Treasury agency determined that the institutions allowed their networks to aid the illegal fentanyl trade of Mexican criminal organizations.

The Treasury’s Financial Crimes Enforcement Network (FinCEN) imposed the restrictions on Mexican banks CIBanco S.A. and Intercam Banco S.A., and brokerage firm Vector Casa de Bolsa, S.A., labeling them as “being of primary money laundering concern.”
