Money Laundering Explained: The 3 Stages, Key Terms, and How They Work

Money laundering usually involves three main stages: placement, layering, and integration. The placement stage introduces illicit funds into the financial system, while layering focuses on moving or transferring those funds to make their origin difficult to trace. During integration, the funds are reintroduced into the economy as seemingly legitimate assets. 

Understanding these stages helps compliance and risk teams identify potential money laundering activity and apply appropriate anti-money laundering (AML) controls. Each stage presents different risks and requires different approaches to detection and prevention. 

What Are the Core Money Laundering Stages? 

The money laundering process is generally divided into three stages: placement, layering, and integration. These stages form a core part of money laundering terminology, explaining how illegally obtained funds can enter the financial system, have their origins concealed, and are eventually made to appear legitimate. 

Placement is the initial phase of the money laundering process, which involves introducing illicit funds into the financial system. This is often considered an important point for detection because the funds are entering the legitimate financial system for the first time.

Layering is the second stage, which involves moving funds through multiple transactions, accounts, or financial arrangements to make their original source harder to detect. The aim of this stage is to create distance between the funds and the activity that generated them.

Integration is the final stage, which occurs when funds are brought back into the legitimate economy and may appear to have come from a lawful source. At this point, tracing the original source can be difficult because the funds may be mixed with apparently legitimate assets or income.

Having a clear understanding of these three stages of money laundering helps businesses and compliance teams recognize potential risk indicators and apply appropriate anti-money laundering (AML) controls.

How Does the Placement Stage Introduce Funds? 

The placement stage of money laundering is the point at which illicit funds are first introduced into the formal financial system. These funds may be generated through fraud, corruption, theft, or other illegal activity. Placement can take different forms, such as depositing funds, transferring money through financial accounts, or using illicit proceeds to acquire assets. 

For example, someone who has obtained proceeds from fraud may try to deposit those funds into a bank account or introduce them through a business as legitimate revenue. In some cases, illicit cash may be divided into smaller amounts or converted into monetary instruments before being deposited. These approaches are designed to introduce the proceeds into the financial system while making their connection to the underlying crime less obvious.  

Placement is not restricted to traditional cash deposits. FATF’s recent work on professional money laundering highlights how bank accounts, fintech platforms, payment service providers, virtual IBANs, prepaid cards, and virtual asset wallets can serve as potential entry and exit points in money laundering schemes.

For compliance teams, this makes the source of funds and the customer’s expected financial activity important considerations. Transactions that do not align with a customer’s profile, business activity, or stated source of funds may warrant further review as part of a broader AML monitoring process.

Why Does Identity Verification Matter During the Placement Stage?

Identity verification is an essential part of customer due diligence when a person or business first enters the financial system. Financial institutions and fintech platforms need to determine who their customers are and, where applicable, verify beneficial owners using reliable and independent information. This helps them understand who is behind an account before financial activity begins.  

For example, if a customer opens an account and later deposits funds that are inconsistent with their known business activity or stated source of funds, the institution can use the customer information it has collected to assess the activity. Identity verification does not by itself detect money laundering, but it provides important context for the broader AML controls used to identify and investigate unusual activity.  

This makes customer onboarding an important control point during the placement stage of money laundering. Establishing a reliable customer profile at the beginning gives compliance teams a stronger basis for identifying activity that may require further review as funds move through the financial system.

How Do Layering and Integration Conceal Funds? 

 The main challenge with layering in money laundering is that it can create a complex trail between illicit funds and their original source. Funds may move through multiple accounts, transactions, jurisdictions, or financial channels, making it difficult for investigators and compliance teams to determine where they originated. As the number of transactions increases, identifying the original source can become much harder without effective transaction monitoring and investigation. 

The integration stage of money laundering presents a different challenge. By this point, funds that have passed through layering may be made to appear as proceeds from legitimate activities, such as business income or investments. This can make source-of-funds checks, transaction monitoring, and customer risk assessments particularly important when activity does not align with what is known about the customer or their business. 

For compliance teams, understanding how layering can lead to integration is essential because suspicious activity may not be obvious from a single transaction. Reviewing transaction patterns alongside customer information and expected activity can provide a clearer picture of potential money laundering risk.
