What is money laundering?

Infographic defining what money laundering is

Money laundering is the process of converting money or assets that derive from criminal activity into 'clean' assets, for the purpose of disguising their illicit origin. This offence covers virtually any act that constitutes a person’s benefit from criminal conduct. These definitions are quite broad and easy to fall under. 

The money laundering process usually involves three stages:

  • stage 1 - placement: criminally derived funds are introduced into the financial system

  • stage 2 - layering: assets are being ‘laundered’ by means of conversion, transfer, or concealment

  • stage 3 - integration: laundered assets are reintroduced into the legitimate economy

Money laundering enables criminal organisations to seep illegal profits into the financial system and facilitates criminal activities such as terrorism, corruption, tax evasion, smuggling, and drug or human trafficking.

Which anti-money laundering laws should you know about?

Infographic defining what anti-money laundering is

It is not only the money laundering offences that business owners and managers should be aware of, but also those offences resulting from a failure to act on a suspicion of money laundering. There are also a variety of administrative and regulatory requirements for firms within the regulated sector.

The primary legislation on this topic includes:

Money laundering offences

There are three main money laundering offences under the POCA relating to the direct handling of the proceeds of crime that can be committed by any person:

  • concealing, disguising, converting, or transferring the proceeds of crime, or removing the proceeds of crime from the jurisdiction of England and Wales

  • entering into, or becoming concerned in an arrangement, in which the person knows or suspects the retention, use, or control of the proceeds of crime

  • acquiring, using, or possessing the proceeds of crime

Offences of failing to report money laundering include:

  • failure to disclose (for employee) - ie when a person working in a business in the regulated sector knows or suspects, or has reasonable grounds for knowing or suspecting, that another person is engaged in an offence above but fails to disclose that knowledge or suspicion to a relevant officer 

  • failure to disclose (for nominated officer) - ie when a person nominated to receive disclosures under the above offence, working in the regulated sector, knows or suspects, or has reasonable grounds to know or suspect money laundering as a consequence of his role and fails to make the necessary disclosure as soon as practical after the information comes to him

  • tipping off - a person working in a business in the regulated sector knows or suspects that another person's suspected involvement with money laundering is under investigation or in contemplation of investigation, and regardless, makes a disclosure to any person likely to prejudice any investigation

  • prejudicing the investigation - a person knows or suspects that a money laundering investigation has, or is about to be, commenced in respect of another, and he makes a material disclosure to any other person which is likely to prejudice the investigation or interfere with relevant material

What obligations do businesses have?

The obligations will depend on whether a business is conducting regulated activities or not. The regulations apply to various business sectors, including accountants, financial services businesses, estate agents, solicitors, and others. Every business covered by the regulations must be monitored by a supervisory authority.

Some businesses may already be monitored because they are authorised by the Financial Conduct Authority (FCA) or belong to a professional body such as the Law Society. If this is not the case and the business conducts regulated activity, the business will need to register with HMRC. You can find out more information about registration requirements on the government’s website

Apart from registration, those businesses will also have to meet certain day-to-day responsibilities. These include carrying out ‘customer due diligence’ measures to check that customers are who they say they are, as well as risk assessments.

They must also put in place internal controls and monitoring systems. The nature of these controls will depend on the size and complexity of the business, including the number of customers, and the number and type of products and services provided.

The business will also have to produce a policy statement that includes its anti-money laundering policy, controls, and the procedures the business has taken to prevent money laundering. They will also need to keep a record of all customer due diligence measures that are carried out, including:

  • customer identification documents that you’ve obtained

  • risk assessments

  • your policies, controls, and procedures

  • training records
