To build effective detective controls, compliance professionals must understand the physical mechanics of financial crime. Money laundering is broken down into three distinct stages. Bad actors alter their methods at each stage to bypass automated transaction monitoring systems.
[Stage 1: Placement] ---> [Stage 2: Layering] ---> [Stage 3: Integration]

1. The Placement Stage
The initial entry of illicit funds into the legitimate financial system. This is the point where criminal cash is most vulnerable to law enforcement detection.
  • Control Detection Strategy: Monitor cash deposits that sit just under regulatory reporting limits, sudden changes in a customer’s typical cash habits, or multiple small deposits made across different branch locations.
2. The Layering Stage
Moving funds through a complex web of transactions to hide the original audit trail, mask the source of the money, and break links to the crime.
  • Control Detection Strategy: Monitor rapid wire transfers sent between accounts with no apparent business relationship, funds routed through offshore tax havens, or sudden changes in ownership for corporate bank accounts.
3. The Integration Stage
Returning the laundered funds into the economy with the appearance of legitimate business wealth or clean personal assets.
  • Control Detection Strategy: Monitor cash purchases of high-value assets (like real estate or luxury goods) financed by offshore corporate wires, or investment in front companies using loans that lack commercial substance.
