Operation Casablanca was a three-year U.S. investigation of major Mexican banking institutions for laundering illicit drug profits. Mexican authorities were not informed about the investigation.

This operations led U.S. Customs agents to arrest 22 high-ranking and mid-level bankers from 12 of Mexico's largest banks when they traveled to the U.S. in mid-May, expecting to attend a banking conference. The investigation produced 160 indictments, including 3 Mexican banks and 26 Mexican bankers. Banorte was among the banks and bankers implicated in money laundry, according to the Operation Casablanca. From the June to July 1998 issue of Money Laundering Alert, Banorte was suspected to have laundered $7,323,103.51,^{[citation needed]} and Banorte faced a civil penalty lawsuit under Title 18, USC Sec. 1956(b) and civil forfeiture action under Title 18, USC Secs. 981 & 984. On July 1, 1999, a U.S. federal judge in Los Angeles dismissed with "extreme prejudice" the forfeiture case against Banorte. No criminal charges were filed and U.S. authorities gave them back $1.4 million seized in the operation. Banorte had implemented anti-money laundering policies and procedures and had detected and closed money laundering accounts prior to Operation Casablanca. These policies and practices assisted Banorte in defending itself against the money laundering charges.
