What is money laundering: a complete guide to schemes and methods

What does money laundering mean? It is one of the key issues in financial regulation and crime prevention. Money laundering involves a set of actions aimed at disguising the origin of illegal proceeds obtained from criminal activity to make them appear legitimate. Understanding what money laundering is is critically important for financial institutions, law enforcement, and society itself.

Definition: What does money laundering mean in modern practice

International regulatory bodies, including the Basel Committee on Banking Supervision, provide a clear definition of this phenomenon. Money laundering is the process by which criminals and their accomplices use the financial system to transfer funds between accounts, carefully hiding the true source of the funds and ownership relationships.

What does money laundering mean in practical terms? It is an attempt by criminal elements to perform one of five key actions: provide accounts for placement of illegal proceeds, help convert assets into cash or securities, facilitate transfers between financial institutions, conduct cross-border transfers, or obscure the true origin of criminally obtained income through other means.

The significance of this phenomenon is twofold: on one hand, organized crime hides traces of its activities to “legally enjoy” criminal proceeds; on the other hand, money laundering allows criminal groups to penetrate legitimate businesses, hiding “behind legal cover” and expanding the scope of illegal activities.

Classic scheme: three stages of money laundering

Theoretically, money laundering goes through three clearly defined stages, each serving a specific purpose in achieving the final goal.

Placement stage — the beginning of the process

The placement stage is the first phase of money laundering. At this stage, illegal proceeds obtained from criminal activity are initially processed and introduced into the financial system. The most common example is criminals receiving large sums of small cash from drug trafficking. Since such money is inconvenient to store and easily attracts attention, it is transformed by depositing into a bank or purchasing securities. Thus, illegal proceeds become more manageable and hidden.

Modern placement methods include using various financial instruments: from traditional cash transactions to wire transfers, credit cards, and even online banking. The development of digital financial markets has provided money launderers with additional opportunities to conceal the origin of funds.

Layering stage — dispersing traces

The layering stage, also known as the “separation” or “shaking” process, is a key link in money laundering. The goal of this stage is to distribute and accumulate illegal proceeds through complex financial operations and transfers of assets, radically changing their appearance so they are detached from the original source.

At this stage, criminals actively use modern financial systems, creating multi-level transaction chains through banks, insurance companies, brokerage firms, precious metals markets, and even retail sectors. They open accounts under fictitious names, perform fictitious trading operations, buy and sell bearer securities, and deliberately mislead auditors and bypass control mechanisms.

The development of cross-border money laundering has further complicated this process. Criminals use “tax havens” and “offshore jurisdictions”—areas with weak regulation and increased confidentiality—allowing them to deeply cloak the nature, source, and movement of criminal funds, making detection difficult even for experienced regulators.

Integration stage — returning to the economy

The final phase, the “merging” or “fusing” stage, is the culmination of money laundering. At this stage, assets that have passed through layering and have weak links to their original illegal source are transformed into the appearance of fully legitimate property. Criminals transfer these funds to the names of legitimate institutions or individuals with no apparent ties to the criminal organization and introduce them into normal economic activity.

If the layering stage was successful, illegal proceeds become indistinguishable from regular cash flows. Criminals gain the freedom to dispose of and use these funds in their new “clean” form, transferring money to accounts of legitimate organizations or individuals, simulating ordinary commercial transactions, and allowing “laundered” funds to circulate again within the financial system with full appearance of legality.

31 methods of money laundering: from traditional to modern

Criminals have developed over thirty different methods of money laundering, ranging from simple physical operations to complex international financial schemes.

Physical smuggling and initial placement

Cash smuggling remains a fundamental method. In countries without strict cash reporting systems, criminals simply import illegal proceeds and then deposit them into banks. This is why many states impose strict limits on the amount of cash allowed to be exported.

The “splitting” method involves dividing large sums of cash into many small deposits, each below the reporting threshold, to avoid triggering bank alert systems.

Use of cash-intensive industries

Money launderers actively use sectors with high cash turnover—casinos, entertainment venues, bars and nightclubs, jewelry stores. They use these establishments as cover, declaring illegal proceeds as legitimate revenue from operations through fictitious transactions.

Purchasing high-value assets

Directly buying real estate, luxury cars, antiques, art, jewelry, and securities is a classic method. These assets are later resold, and the proceeds are deposited into banks as supposedly “clean” income from sales.

Use of financial instruments

Securities, stocks, bonds, and futures offer vast opportunities due to the scale and complexity of the securities market. Many criminals buy insurance policies for large sums and then receive premium refunds as “legitimate” insurance payouts, creating the appearance of lawful income.

Offshore schemes

Some jurisdictions allow the creation of fully anonymous companies or provide excessive confidentiality regarding personal assets. After criminal proceeds enter these regions, tracing the true source of funds becomes nearly impossible.

Fake foreign trade

Fictitious companies are created to conduct trade operations with disproportionate prices. For example, criminals may import goods at inflated prices or export at undervalued prices, using pricing manipulations to transfer money across borders under the guise of commercial payments.

Methods of corrupt officials

Some officials first accumulate income from corruption, then create or invest in enterprises using these funds, giving the appearance of “self-made” wealth. Others use relatives to open businesses and restaurants, complicating the tracking of income sources and business links.

Cross-border transfers

Criminals use non-trade methods—sending children abroad and transferring “educational contributions” in foreign currency. Trade methods include over-invoicing imports and under-invoicing exports with kickbacks through foreign partners. Another method involves setting up shell companies abroad to invest illegal proceeds under the guise of foreign investments.

Underground banks play a role in cross-border transfers. In the famous “Yuanhua” case, 12 billion yuan were transferred through underground banks in Jinjing and Shishi, then smuggled into Hong Kong via international banking channels.

Bribing financial regulators

Drug traffickers and other criminal groups bribe senior officials of financial authorities to weaken oversight and permit cross-border transfers. In 2001, Hong Kong’s Independent Commission Against Corruption uncovered the city’s largest money laundering ring, involving about HKD 50 billion. Criminals opened accounts at a branch in Tsim Sha Tsui and, by bribing managers, transferred funds between accounts, bypassing standard reporting procedures.

Use of financial systems and the internet

Criminals open multiple bank accounts with fake documents, using online banking to transfer illegal proceeds. Some even use online gambling operations to “launder” money through winnings in virtual casinos.

Investment schemes

Money laundering through investments in hotel construction, company formation, commercial real estate purchases, and residential property investments. Some criminals open companies abroad, giving their illicit income the appearance of international business activity.

Import-export manipulations

Over-invoicing imports and under-invoicing exports enable cross-border money transfers under the guise of commercial payments or facilitate foreign fund inflows. Forged trade documents enhance the masking effect.

Terrorist checks

Unlike cash, traveler’s checks have no limits on crossing borders. Criminals buy checks and pass them to third parties for deposit into foreign accounts without direct tracking via serial numbers.

Casino and gaming operations

In casinos, criminals exchange money for chips, which are then cashed out (usually with about 5% commission), claiming winnings. This method helps avoid direct tracking through banknote serial numbers.

Jewelry, antiques, and collectibles

Purchasing expensive jewelry, antiques, stamps, historical musical instruments, and reselling them as collectibles. Fake appraisals are used to inflate prices during resale.

Charitable foundations

Politicians and businesses create foundations, make donations under the guise of charity, then “move money from left to right,” avoiding taxes. Disaster relief funds are often used to collect funds that are later diverted for private use.

Fake accounts and micro-transfers

Fake documents are used to open accounts unknown to the account holders themselves. The “ants moving bricks” method involves numerous small deposits over different days to accumulate large sums without triggering suspicion.

Real estate speculation

Shell entities buy property from developers at 50-70% of market value, then quickly resell with a 50-100% profit, transforming illegal funds into investment-like income.

Fake loans and promissory notes

Illicit income recipients receive promissory notes or checks with deferred payment, which can be presented as loans upon discovery. After interest wanes, the note is transferred to a third party or deposited into a bank for repayment.

Counterfeit money and coins

Fake coins or banknotes are used for many small consumer transactions or vending machine exchanges, legitimizing counterfeit money as real currency.

Gift certificates

Gift certificates from department stores are highly liquid. Criminals resell them to companies for employee bonuses, laundering certificates through unsuspecting third parties and receiving cash back.

Underground currency exchange

Underground jewelry shops conduct illegal currency exchanges and even issue bearer foreign checks, allowing clients to deposit them into foreign accounts without direct reporting.

Cross-border corporate fund transfers

Banks, insurance companies, and financial institutions transport large amounts of cash across borders under the guise of corporate transactions.

Cryptocurrency operations

In recent times, criminals increasingly use cryptocurrencies for money laundering, leveraging their decentralized nature and relatively low cross-border transaction traceability.
