When Commerce Becomes Collusion: Inside a Black-Market Peso Exchange Money Laundering Plot

On July 21, 2025, two Mexican nationals were sentenced to 55 months in U.S. prison—plus substantial fines—for orchestrating a multimillion-dollar trade-based money laundering scheme using the black-market peso exchange in Laredo, TX. By disguising drug trafficking proceeds as cash-for-merchandise trades, they facilitated cartel financing without physically crossing the border. Storefronts in Laredo played key roles, acting as exchange points for dirty money tied to cartel networks.

Why it matters: Criminals are leveraging legitimate trade and small businesses to mask illicit flows—exposing vulnerabilities in financial systems and cross-border trade visibility.
