US banks can no longer send money through a Mexican brokerage tied to opioids

The US Treasury's financial crime unit has banned certain money transfers involving a specific Mexican financial firm. This means US banks and businesses cannot use Vector Casa de Bolsa to move funds, because the US says the firm helps launder money for opioid trafficking.

The US government is directly cutting off a financial artery it believes funds illegal opioid operations. This makes it harder for drug traffickers to move their money through established financial systems. It also puts other financial institutions on notice about who they can and cannot do business with.
