Money laundering involves disguising illegally obtained money to make it appear legitimate. It typically involves three stages: placement, layering, and integration. Placement involves injecting dirty money into the financial system. Layering involves moving funds through transactions to obscure the audit trail. Integration makes the money appear legitimate through reentry into the economy. Money laundering undermines legitimate businesses, increases organized crime and corruption, and threatens the stability of financial institutions. It can also dampen foreign investment.
