Money Laundering is a major criminal activity in the financial world that can’t be taken lightly. It’s the process of disguising the origins of money obtained through illegal means like fraud, terrorism, drug trafficking etc. Criminals can hide their crimes and make the dirty money appear as if it is clean by “laundering” money acquired by illegal activities through legitimate business practices. This is where anti-money laundering (AML) measures come into play. By having AML measures in place, money launderers can be caught in the act and stopped from exploiting businesses for unlawful gain.

What is Money Laundering?

Money Laundering is the process of concealing where money acquired through illegal activities came from and making it seem like it was acquired legitimately. Here are some examples of activities that are known for producing “dirty money”:

  • Drug Trafficking
  • Human Trafficking
  • Fraud schemes like investment scams or tax evasion
  • Bribery and corruption
  • Terrorism financing
  • Theft and extortion


There are 3 stages criminals attempt to launder their dirty money:

  1. Placement – Placing illegal proceeds into the financial system through methods like depositing cash into bank accounts or purchasing assets.
  2. Layering – Moving the funds around to obscure the money trail and create distance from the original crime. This often involves transferring money across multiple accounts, businesses, and jurisdictions.
  3. Integration – Making the money appear legitimate through activities like investing in real estate or business ventures. The laundered money is now “clean.”

What are Anti-Money Laundering Measures?

AML measures refer to the policies, procedures and controls that businesses and institutions put in place to detect and prevent money laundering activities.

Having a strong AML program is crucial for a few key reasons:

  1. Compliance – AML regulations like the Proceeds of Crime Act 2002 and Money Laundering Regulations 2017 require certain businesses to implement appropriate risk-based prevention measures. Failure to comply can result in heavy fines and penalties.
  2. Reputational Risk – Being inadvertently involved in money laundering scandals can severely damage a company’s reputation, consumer trust, and ability to operate.
  3. Avoiding Criminal Facilitation – Under UK law, businesses and employees can be criminally prosecuted for failing to report suspected money laundering or for becoming involved in the process unwittingly.

For the rest of this guide we will discuss common anti-money laundering controls.

Customer Due Diligence (CDD)

The first money laundering control measure we will discuss is Customer Due Diligence (CDD). CDD is verifying customer identities through documentary evidence and other background checks to detect potential money laundering risks. There are 3 main levels of CDD:

  1. Simplified Due Diligence For lower-risk customers like public companies or UK public authorities, firms can perform a more basic identity verification.
  2. Standard Due Diligence For most individual and corporate customers, firms must obtain:
  • Proof of identity documents (passport, driver’s license)
  • Proof of address (utility bill, bank statement)
  • Information on the nature and purpose of the business relationship
  1. Enhanced Due Diligence For high-risk customers or situations (e.g. Politically exposed people), more thorough enhanced checks are required, such as:
  • Identifying source of funds and source of wealth
  • Increased monitoring of business relationship
  • Obtaining additional data from credible third-party sources

Firms must have risk assessment procedures to determine the appropriate CDD level for each customer scenario. Records of CDD checks must be kept for at least 5 years after the business relationship ends.

Know Your Customer (KYC)

KYC is collecting and analysing customer information like sources of funds, wealth, and transactions to ongoing monitoring for suspicious activity.

Comprehensive KYC procedures play a vital role in anti-money laundering by helping businesses:

  • Understand the customer’s background, source of funds, and reason for the business relationship
  • Assess the money laundering risks associated with that customer
  • Monitor customer transactions and activity for suspicious patterns
  • Maintain up-to-date customer information through periodic reviews

Common KYC requirements include obtaining and verifying details such as:

For Individual Customers:

  • Full legal name, date of birth, address
  • Identification documents
  • Employment details and source of income/wealth
  • Expected account activity and transaction volumes

For Corporate Customers:

  • Company registration details
  • Ownership and control structure
  • Nature of business activities
  • Source of corporate income/funds

By developing a comprehensive customer risk profile through KYC, firms can more effectively monitor for unusual or suspicious patterns that could indicate money laundering.

Transaction Monitoring

Transaction monitor involves monitoring customer transactions and activity for red flags that could indicate money laundering, such as irregular cash deposits, rapid movement of funds, etc.

Effective transaction monitoring allows businesses to identify unusual transaction patterns that could indicate money laundering schemes like:

  • Rapid movement of funds between multiple accounts
  • High volumes of large or round-number transactions
  • Transactions with high-risk jurisdictions
  • Deposits of cash or negotiable instruments inconsistent with known income

Financial institutions typically employ a mix of automated transaction monitoring systems and human analysis to detect suspicious activities. Automated systems use specialized software and algorithms to identify transactions meeting certain risk criteria defined by the bank.

An example of this would be an automated system potentially flagging any cash deposits over £10,000 for further review by an analyst. The analyst would then investigate the transaction details, customer information, expected account activity and other factors to determine if it represents truly suspicious money laundering behaviour or is legitimate.

In addition to cash transactions, effective monitoring should also review:

  • Electronic funds transfers
  • Letters of credit transactions
  • Purchases of cash instruments (e.g. cashier’s checks)
  • Loan payments and pay-downs
  • Currency exchange transactions

By baselining number and pattern of customer transactions over time, monitoring systems can detect significant deviations that could expose money laundering.

Robust transaction monitoring allows firms to meet anti-money laundering regulatory requirements while protecting themselves from being exploited by bad actors. It serves as an essential preventative control.

Anti-Money Laundering (AML)

Suspicious Activity Reporting (SARs)

This is when you have processes to report suspicious transactions to the UK’s Financial Intelligence Unit (National Crime Agency).

A core requirement under the UK’s Money Laundering Regulations is the obligation for regulated firms to report any suspected money laundering activities to the appropriate authorities.

This reporting of suspicious activities is done through Suspicious Activity Reports (SARs) submitted to the UK Financial Intelligence Unit (UKFIU) which is housed within the National Crime Agency.

Some key points about Suspicious Activity Reporting requirements:

  • Firms must have internal procedures and controls to identify and report suspicious activities
  • SARs must be submitted promptly after suspicion is first formed
  • Reports should contain all relevant Know Your Customer information and transaction details
  • Both attempted and completed transactions that appear suspicious must be reported
  • Tipping off the suspected individual that a disclosure has been made is a criminal offense

Common examples of activities that should trigger a SAR include:

  • Transactions involving high-risk jurisdictions with weak AML laws
  • Customers providing suspicious or inconsistent information
  • Large cash transactions that are inconsistent with known income/activities
  • Structuring transactions to avoid reporting thresholds
  • Unexplained wealth or income from unknown/unverified sources

Failure to submit a SAR can potentially result in unlimited fines for businesses as well as prison sentences of up to 5 years for individuals found guilty of money laundering offenses.

Developing robust SAR policies, procedures and internal reporting channels allows firms to meet their legal obligations while uncovering potential money laundering risks.

AML Training and Awareness Programs

Providing AML training to staff and having designated compliance personnel to oversee the AML program.

Having proper anti-money laundering policies and procedures in place is crucial, but they won’t be effective without a strong training and awareness program. Equipping employees with the knowledge to identify potential money laundering risks is vital.

UK regulations require relevant firms to provide AML training to their staff on an ongoing basis. At a minimum, AML training programs should cover:

  • The firm’s specific AML policies, controls and reporting procedures
  • How to identify red flags and suspicious activities
  • Examples of common money laundering typologies and techniques
  • Relevant AML laws and regulations
  • Roles, responsibilities and disciplinary consequences related to AML


Best practices recommend taking a risk-based approach, providing enhanced training to roles with higher exposure to potential money laundering risks like:

  • Front-line staff handling cash transactions
  • Relationship managers overseeing high-risk client accounts
  • Compliance officers responsible for monitoring and reporting


Maintaining AML awareness is also important. Tactics can include periodic staff reminders, newsletter updates on emerging typologies, and channels for asking questions or reporting concerns.

Some firms go as far as to conduct periodic tests of staff AML knowledge through techniques like:

  • Screening test questions during training sessions
  • Simulating suspicious transactions to assess if they are properly identified
  • Reviewing quality samples of filled-out CDD forms and SAR reports

Having an AML training and awareness program is essential for making anti-money laundering measures effective on a day-to-day operational level.

The consequences of inadvertently facilitating money laundering – whether it’s hefty fines, criminal prosecutions, or irreparable reputational damage – are simply too severe to ignore. Prioritizing strong anti-money laundering controls has to be a key strategic focus.
