Money Laundering

The process of disguising the origin of money obtained from crime so it appears legitimate. It typically moves through placement, layering, and integration stages to break the link to the underlying offence.

Related: Placement, Layering, Integration
Placement

The first stage of money laundering, where criminal cash enters the financial system. Examples include depositing small amounts across branches, buying assets, or using cash-intensive businesses to absorb illicit funds.

Related: Money Laundering, Smurfing, Layering
Layering

The stage of laundering that separates funds from their source through complex transactions. Rapid transfers, offshore accounts, shell companies, and converted assets are used to obscure the audit trail.

Related: Placement, Integration, Shell Company
Integration

The final laundering stage, in which funds re-enter the legitimate economy looking clean. The criminal can then use them for investment, property purchase, or ordinary spending without attracting suspicion.

Related: Layering, Placement
Predicate Offence

The underlying crime that generates proceeds requiring laundering, such as fraud, drug trafficking, or tax evasion. Supervisors expect firms to treat proceeds of any listed offence as reportable.

Related: Money Laundering, Suspicious Activity Report
Suspicious Activity Report

A confidential disclosure to the financial intelligence unit describing activity that may indicate laundering or terrorist financing. Firms file it promptly and must not tip off the customer that a report was made.

Related: Tipping Off, Financial Intelligence Unit, Predicate Offence
Tipping Off

Disclosing to a customer or third party that a suspicious activity report has been filed or that an investigation is underway. It is a criminal offence because it can undermine detection and enforcement.

Related: Suspicious Activity Report
Customer Due Diligence

The checks a firm performs to identify and verify customers and understand their expected activity. It covers identity, beneficial ownership, purpose of the relationship, and ongoing monitoring.

Related: Enhanced Due Diligence, Beneficial Owner, Know Your Customer
Enhanced Due Diligence

Additional scrutiny applied to higher-risk relationships, such as politically exposed persons or customers in high-risk jurisdictions. It involves deeper source-of-funds checks, senior sign-off, and more frequent review.

Related: Customer Due Diligence, Politically Exposed Person, Risk-Based Approach
Simplified Due Diligence

Reduced verification measures permitted where the risk of laundering is demonstrably low, for example certain listed public bodies. The firm must still identify the customer and document why lower measures apply.

Related: Customer Due Diligence, Risk-Based Approach
Beneficial Owner

The natural person who ultimately owns or controls a customer or the funds involved, often identified by a shareholding threshold. Firms must look through corporate structures to find them.

Related: Customer Due Diligence, Shell Company
Politically Exposed Person

A person entrusted with prominent public functions, plus close associates and family members. Their position creates higher corruption risk, so firms apply enhanced scrutiny and senior approval before onboarding.

Related: Enhanced Due Diligence, Source of Funds
Source of Funds

Evidence showing where the money used in a transaction came from, such as salary, property sale, or inheritance. It differs from source of wealth, which explains the total accumulated fortune.

Related: Source of Wealth, Enhanced Due Diligence
Source of Wealth

An explanation of how a customer accumulated their overall fortune, supported by documents such as business sale records or probate papers. It establishes the legitimacy of the whole relationship, not one payment.

Related: Source of Funds, Politically Exposed Person
Risk-Based Approach

Allocating compliance resources according to assessed risk rather than applying identical controls to everyone. Higher-risk customers receive more scrutiny, while lower-risk ones may receive proportionate, lighter measures.

Related: Enhanced Due Diligence, Simplified Due Diligence, Risk Assessment
Risk Assessment

A documented evaluation of how exposed a firm is to laundering and terrorist financing through its customers, products, channels, and countries. It drives the design of policies, controls, and monitoring thresholds.

Related: Risk-Based Approach, Ongoing Monitoring
Ongoing Monitoring

Continuous review of transactions and relationships against the expected profile to spot unusual activity. It includes periodic refresh of customer information and scrutiny of transactions that fall outside the norm.

Related: Customer Due Diligence, Risk Assessment
Know Your Customer

The overall process of establishing who a client is, what they do, and whether the relationship makes sense. It underpins onboarding decisions and feeds later monitoring and reporting.

Related: Customer Due Diligence, Beneficial Owner

The national body that receives and analyses suspicious activity reports and shares findings with law enforcement. Firms report to it and may receive requests for further information.

Related: Suspicious Activity Report, Supervisory Authority
Supervisory Authority

The regulator that monitors whether firms comply with anti-money laundering obligations. It can inspect, request records, impose remediation requirements, and sanction failures.

Related: Financial Intelligence Unit, Risk Assessment
Shell Company

An entity with no meaningful operations or assets, often used to hold accounts or move money while hiding who controls it. Its opacity makes it a common laundering vehicle requiring close scrutiny.

Related: Beneficial Owner, Layering
Smurfing

Structuring cash deposits or withdrawals into small amounts to stay below reporting thresholds or avoid attention. It is a recognised red flag and may itself constitute a criminal offence.

Related: Placement, Red Flag
Red Flag

A warning indicator suggesting possible laundering, such as unusually large cash payments, reluctance to provide identification, or transactions with no clear business purpose. Red flags prompt further enquiry and possible reporting.
