Money laundering conceals or disguises property connected to crime. Learn the stages model, common typologies, evidence, and AML review process.
Money laundering is conduct intended to conceal, disguise, move, convert, or use property connected to crime so that its illicit origin, ownership, location, movement, or control is harder to identify. The exact offense and required knowledge or intent depend on the law that applies.
Money laundering is not limited to cash, offshore accounts, or large transactions. It can involve bank deposits, securities, businesses, real estate, trade documents, digital assets, payment services, or ordinary purchases. A transaction pattern can be a warning sign without proving that the property is criminal proceeds or that a person committed an offense.
Money laundering is often explained through three stages:

A["Crime generates proceeds"] --> B["Placement: introduce or position value"]
B --> C["Layering: complicate the transaction trail"]
C --> D["Integration: use value with apparent legitimacy"]
Placement introduces or positions proceeds within a financial or commercial channel. Examples can include depositing cash, purchasing instruments, paying business receipts into an account, or converting value into another asset.
Layering uses transactions or legal arrangements to distance property from its source or controller. Transfers among accounts, entities, assets, or jurisdictions can make the trail more difficult to reconstruct.
Integration makes the property available for spending, investment, lending, or business use with an appearance of legitimacy.
Real cases do not always follow this sequence. Proceeds from account fraud may already exist inside the banking system. A single purchase can both conceal ownership and put property to use. Some conduct can satisfy an applicable offense without completing all three stages.
A typology is a recurring method or pattern used to understand risk. It is not proof that every transaction with that shape is unlawful.
| Typology | What an analyst examines | Legitimate activity that may look similar |
|---|---|---|
| Cash placement | Cash volume, business purpose, aggregation, locations, and source | Retail, hospitality, transport, or other cash-intensive trade |
| Structuring | Whether transactions were arranged to evade a reporting or recordkeeping rule | Distributed deposits from separate stores or agents |
| Shell or front entities | Beneficial ownership, actual operations, invoices, counterparties, and control | Holding companies, acquisition vehicles, or pre-operating businesses |
| Trade-based laundering | Price, quantity, shipment, invoice, payment, and counterparty inconsistencies | Commercial disputes, errors, unusual but genuine goods, or volatile prices |
| Rapid movement | Funds received and quickly transferred, converted, or withdrawn | Payroll, treasury sweeps, escrow, remittances, or marketplace settlement |
| Asset conversion | Repeated movement among securities, property, commodities, or digital assets | Portfolio rebalancing, hedging, business investment, or ordinary purchases |
| Third-party payments | Why someone other than the named customer funds or receives value | Agency, family support, group treasury, or payment-processing arrangements |
The useful question is not whether one label applies. It is whether the customer, purpose, ownership, source of funds, transaction path, and supporting records form a coherent lawful explanation.
Assume a procurement manager receives undisclosed kickbacks from a supplier. Rather than receiving one direct payment, the manager controls a company that issues false consulting invoices. Payments move through that company, pass to another entity controlled by a relative, and are later used toward a property purchase.
The review should separate the evidence:
An unusual invoice or payment to a relative is not enough by itself. The conclusion depends on linked records and the legal elements of the relevant offenses.
| Concept | Main issue | Does it require criminal proceeds? |
|---|---|---|
| Money laundering | Concealing, moving, converting, or using property connected to crime | Generally tied to criminal proceeds, subject to the governing offense |
| Structuring | Evading a covered reporting or recordkeeping requirement | Not necessarily |
| Fraud | Obtaining property or advantage through deception or another prohibited act | Fraud may generate proceeds that are later laundered |
| Sanctions evasion | Avoiding restrictions involving designated parties, regions, goods, or transactions | Not necessarily |
| Terrorist Financing | Raising, moving, storing, or using funds or assets for a prohibited terrorist purpose | No; source funds may be lawful or unlawful |
The same activity can raise several issues. A payment can involve fraud proceeds, sanctions exposure, and money laundering, but each conclusion requires its own facts and legal analysis.
A risk-based review commonly connects four layers of evidence:
The institution then follows its documented process for investigation, escalation, account decisions, recordkeeping, and any required regulatory report. Requirements differ across covered institutions and jurisdictions. Staff should not infer a filing obligation from a public checklist alone.
In the United States, the Bank Secrecy Act and implementing regulations establish reporting, recordkeeping, and program requirements for covered financial institutions. Suspicious Activity Reports are confidential; institutions and employees must follow applicable restrictions on disclosing whether a SAR exists.
Potential indicators can include:
Each indicator can have an innocent explanation. A sound review considers both supporting and contradictory evidence, avoids assumptions based on nationality or customer class, and records why the final disposition is reasonable.
Identify the legal entity and account, beneficial owners and controllers, source of funds or wealth where relevant, transaction purpose, counterparties, dates, jurisdictions, instruments, and downstream use. Reconcile customer explanations to contracts, invoices, bank records, trade data, company records, and other reliable evidence.
