Money laundering

Money laundering is the process of disguising the proceeds of crime so they appear to have a legitimate origin. It is criminalised in the UK by the Proceeds of Crime Act 2002 and is conventionally understood in three stages: placement, layering and integration.

Money laundering is the process of taking the proceeds of criminal conduct and making them appear to derive from a legitimate source. In the UK the substantive offences are contained in Part 7 of the Proceeds of Crime Act 2002 (POCA): concealing criminal property under section 327, becoming concerned in an arrangement under section 328, and acquiring, using or possessing criminal property under section 329. These offences carry a maximum penalty of 14 years’ imprisonment and apply to everyone, not only to regulated firms.

The three stages of money laundering

Money laundering is conventionally analysed in three stages. Placement is the introduction of criminal proceeds into the financial system, for example by depositing cash. Layering involves moving the funds through a series of transactions, transfers or conversions to distance them from their origin and obscure the audit trail. Integration is the final stage, where the funds re-enter the legitimate economy as apparently clean assets, such as property or business investments. In reality these stages frequently overlap.

Why it matters

Understanding the stages helps firms recognise where their products are most vulnerable. Cash-intensive businesses are exposed at placement; correspondent banking and complex corporate structures at layering; high-value asset markets at integration. Recognising activity consistent with any stage may give rise to a duty to report under section 330 of POCA, where a person in the regulated sector knows or suspects, or has reasonable grounds to suspect, money laundering.

Who it applies to

The criminal offences apply to everyone; the reporting and prevention duties fall on the regulated sector under POCA 2002 and the Money Laundering Regulations 2017.

Frequently asked questions

What are the three stages of money laundering?
Money laundering is conventionally described in three stages: placement, where criminal cash enters the financial system; layering, where funds are moved through complex transactions to obscure their origin; and integration, where the laundered money re-enters the legitimate economy as apparently clean assets. The model is widely used in training, though real schemes often blur the stages.
What law criminalises money laundering in the UK?
The principal money-laundering offences are set out in Part 7 of the Proceeds of Crime Act 2002: concealing criminal property (section 327), arrangements (section 328) and acquisition, use or possession of criminal property (section 329). These offences carry a maximum of 14 years' imprisonment and apply to anyone, not only regulated firms.
