What is Money Laundering: A Complete Guide to Criminal Schemes

Money laundering is the process by which criminals hide the origins of illegally obtained funds, making them appear legitimate. This phenomenon affects financial systems worldwide and requires a deep understanding of its mechanisms. In this article, we will explore how this criminal activity operates and what methods offenders use.

Money laundering is not just a crime — it’s a complex process involving numerous financial transactions across multiple countries. According to the Basel Committee on Banking Supervision, criminals use the financial system to transfer funds between accounts, disguising the true beneficiary and source of the funds. The target of such operations is “dirty money” — income from drug trafficking, smuggling, corruption, and other crimes.

Definition of money laundering and its role in the financial system

Money laundering serves two key functions for organized crime. On one hand, it conceals traces of criminal activity, allowing offenders to “legally enjoy” their illicit gains. On the other hand, money laundering is a way to integrate criminal structures into legitimate business, enabling them to expand under the “cover of law.”

Subjects of this crime can be both financial institutions and individuals who perform one of the following actions:

• Providing accounts for illegal funds
• Assisting in converting criminal assets into cash or securities
• Facilitating bank transfers and other settlements
• Transferring funds abroad
• Masking the origin of criminal proceeds by other means

Three key stages: how it happens in practice

Money laundering is a multi-level process consisting of three main stages. Understanding each stage is critical for identifying suspicious activity.

First stage: placement (introduction into the system)

At this initial stage, criminals introduce “dirty” cash into the financial system. This usually involves converting small bills into more convenient forms — checks, securities, or other financial instruments.

For example, criminals who receive large sums of small-denomination bills from street deals face transportation and storage issues. Therefore, they deposit these funds into banks or exchange them for securities. Modern financial technologies have expanded the possibilities of this stage — now online transfers, electronic wallets, and mobile banking are available.

Second stage: layering (dividing and confusing)

Money laundering is an art of creating a labyrinth of transactions. During the layering stage, criminals perform numerous operations to break the link between illegal funds and their source. They use:

• Opening accounts under fictitious names and through shell companies
• Multiple transfers between different countries and accounts
• Buying and selling bearer securities
• Operations in “tax havens” and “offshore centers”
• Engaging in complex, multi-step deals

If these operations are conducted in countries with weak anti-money laundering controls, criminals gain additional protection. The nature, source, and purpose of the funds become nearly impossible for regulators to trace.

Third stage: integration (legalization)

Money laundering concludes at the integration stage, where “laundered” funds are introduced into normal economic activity. Criminals transfer assets to the names of legitimate organizations or individuals with no ties to criminal groups. Then, the funds circulate in regular commercial activities — indistinguishable from legal income and freely usable by criminals.

31 methods and techniques used by criminals

Money laundering is a constantly evolving phenomenon. Offenders adapt their methods to new technologies and regulatory requirements. Here are the main techniques they employ:

Classic cash methods:

1. Smuggling cash across borders into countries with weak reporting systems
2. Splitting large amounts into smaller deposits to avoid suspicious activity reports
3. Using cash-intensive sectors — casinos, entertainment venues, restaurants, jewelry stores

Methods involving assets and securities: 4. Direct purchase of expensive property (homes, cars, antiques, art) 5. Investing in securities, bonds, futures 6. Buying insurance policies for large sums with subsequent partial refunds via claims

Methods through financial systems: 7. Using offshore financial centers and tax havens 8. Creating shell companies for fictitious transactions 9. Operations through underground banks and unofficial money transfer systems 10. Bribing high-ranking officials in the financial sector

Corruption and appearance of legality: 11. “Earn first, then launder” — corrupt officials earn money and then create companies to give the income a legal appearance 12. “Earn and launder simultaneously” — relatives of corrupt officials run businesses, hiding true connections 13. “Dual role” — government officials establish private companies managed by proxies 14. Direct fictitious loans disguised as credit agreements

Real estate methods: 15. Speculating in real estate via shell buyers 16. Buying from developers at 50-70% below market value for quick resale

Foreign trade methods: 17. Overstating import prices and understating export prices 18. Contracting with foreign partners to receive kickbacks 19. Creating shell firms for fictitious export/import

Cross-border methods: 20. Transferring funds abroad via education services, insurance premiums, and commissions 21. Using offshore companies to invest illicit proceeds 22. Transferring through underground banks (as in the Yuanhua case, where 12 billion yuan was transferred via underground banking networks) 23. Opening secret accounts unknown even to proxies

Methods to evade control: 24. Using “ant streams” — numerous small transfers disguised as personal transactions 25. Intermediating through currency accounts with subsequent withdrawal of foreign currency 26. Using traveler’s checks with no restrictions in most countries

Gambling establishments: 27. Indirect exchange of gaming chips — criminals exchange money for chips, then pass them to third parties who cash out, hiding the original source

Art and collectibles: 28. Buying and selling antiques, jewelry, rare items with fake valuation documents 29. Private deals involving luxury cars, private jets, and high-end items

Charity methods: 30. Creating foundations under the guise of charity with fictitious donations 31. Using disaster relief funds to collect and misappropriate funds

Modern technologies: 32. Using online banking for high-speed transfers 33. Internet gambling to legitimize funds 34. Cryptocurrencies — a new frontier in money laundering due to anonymity and fast transactions

Historical examples and scale of the problem

Money laundering is a global issue. In 2001, Hong Kong’s Independent Commission Against Corruption uncovered the city’s largest money laundering network, with an estimated $6.4 billion HKD laundered. Criminals opened accounts at Baosheng Banking Group, bribed senior managers, and conducted numerous bank transfers disguised as legitimate transactions to avoid detection.

Another major case is Yuanhua, where 12 billion yuan was transferred through underground banks in Jinjiang and Shishi. Funds were moved via underground financial channels with notifications to Hong Kong partners for final currency conversion.

Why money laundering remains a challenging problem

Money laundering poses a challenge for regulators due to the constant improvement of criminal methods. As financial technologies evolve, new ways to mask funds emerge. The cross-border nature of transactions complicates detection, and offshore centers with weak oversight provide additional cover.

Understanding that money laundering is a serious threat is the first step toward prevention. Financial institutions, government agencies, and international organizations must continually improve suspicious activity detection systems and share information to combat this global threat.
