Money laundering typically moves through three stages. Understanding each one is the foundation of every effective anti-money laundering programme.
Quick answer
The three stages of money laundering are placement (introducing illicit cash into the financial system), layering (moving it through complex transactions to disguise its origin), and integration (returning the now clean-looking funds to the criminal as apparently legitimate wealth). The United Nations Office on Drugs and Crime (UNODC) uses this three-stage model, while noting that real cases don’t always follow it neatly.[1]
Why this matters
Money laundering is the process of disguising the proceeds of crime so they can be used without attracting attention. Its scale is enormous: the UNODC estimates that between 2% and 5% of global GDP — somewhere between roughly $800 billion and $2 trillion — is laundered each year, though the true figure is impossible to measure precisely because most of it goes undetected.[1]

The standard framework, used by regulators and bodies such as the UNODC and the Financial Action Task Force (FATF), breaks the process into three stages. An effective AML programme is designed to interrupt the cycle at each one.[1]
Stage 1 — Placement
Placement is the point at which “dirty” money first enters the legitimate financial system — for example through cash deposits, buying assets, or routing money through cash-intensive businesses. It is the most visible and riskiest stage for the criminal, because moving large amounts of cash is exactly what AML controls are built to detect. A common tactic is “structuring”: breaking a large sum into many smaller deposits to stay under reporting thresholds.[2]
Stage 2 — Layering
Layering is the most complex stage. Once the money is in the system, it is moved through a series of transactions designed to sever the link to its criminal origin — wire transfers between accounts, banks and jurisdictions, currency conversions, and routing through shell companies in secrecy jurisdictions. A single layering operation might move funds through several banks across multiple countries, convert them between currencies, and pass them through shell companies before they re-emerge looking legitimate.[3] Cryptocurrency “mixing” or “tumbling” is an increasingly common modern layering technique.[4]
Stage 3 — Integration
Integration is the final stage, where the now clean-looking funds are returned to the criminal as apparently legitimate wealth — through property purchases, business investments, luxury assets, or fake loans and salaries. By this point the money is nearly impossible to distinguish from legitimate wealth, which is why detection at the earlier stages matters so much.[3]
| Stage | What happens | Common techniques | Detectability |
|---|---|---|---|
| Placement | Dirty cash enters the financial system | Cash deposits, structuring, cash-intensive businesses | Highest — most visible |
| Layering | Origin disguised through complex transactions | Wire transfers, shell companies, crypto mixing | Hardest to follow |
| Integration | Clean-looking funds returned to the criminal | Property, business investment, fake loans/salaries | Very low once complete |
The UNODC is explicit that this is a model, not a rule: real cases “may not have all three stages, some stages could be combined, or several stages repeat several times.”[1]

“Property and professional services sit right in the path of the integration stage — which is why client onboarding checks aren’t a formality. They’re often the last line of defence before criminal money looks completely clean.”

How AML programmes disrupt each stage
- At placement: identity verification, source-of-funds checks and cash-handling controls at onboarding.
- At layering: transaction monitoring and sanctions/PEP screening to spot unusual movement.
- At integration: due diligence on high-value purchases — the point where regulated firms like estate agents and solicitors become the last line of defence.

Frequently asked questions
What are the three stages of money laundering?
Placement (introducing illicit funds into the financial system), layering (disguising their origin through complex transactions), and integration (returning the clean-looking funds to the criminal).
What are the three types of money laundering?
This usually refers to the same three stages — placement, layering and integration — rather than distinct ‘types’. Methods within them include cash structuring, shell companies and property investment.
What is the hardest stage to detect?
Integration is the hardest to detect once complete, because the funds appear legitimate. Placement is the easiest to spot, which is why criminals take the most risk there.
How much money is laundered globally?
The UNODC estimates 2–5% of global GDP — roughly $800 billion to $2 trillion — is laundered each year, though most goes undetected.
