The three core stages of money laundering are Placement, Layering, and Integration, a process designed to disguise illegal money as legitimate funds by first introducing it into the financial system (Placement), then obscuring its origins through complex transactions (Layering), and finally making it appear as clean, usable wealth (Integration). While some legal frameworks define different types of offenses (like domestic vs. international) or prohibited acts (concealing, arranging, acquiring), the fundamental process remains these three steps.
Signs of money laundering include unusual transaction patterns (rapid movement, large cash amounts, complex structures, high-risk jurisdictions), customer behavior (evasiveness, providing false info, reluctance to ID), and inconsistent business activity (e.g., cash-heavy businesses with unexplained high turnover or losses). Key indicators involve using shell companies, third-party payments, virtual assets, and frequent, unexplained fund movements.

This usually involves complex financial transactions over three stages: placement (introducing cash), layering (obscuring the trail), and integration (reintroducing it as clean funds).
