Layering

Anyone holding money from a crime has a problem: the money can be traced back. So it gets pushed back and forth in many small steps. It moves between accounts, countries, companies, and sometimes even between different currencies. After a hundred such steps, it’s barely recognizable where it originally came from. This deliberate blurring of the trail is exactly what is called layering. It is the middle of three stages of money laundering, that is, the process of making illegal money look legal.

The middle stage between placement and return

Experts divide money laundering into three phases. First comes placement: the cash first has to get into the financial system at all. It is deposited, for example, in small amounts or spent as revenue in a cash-intensive business like a restaurant. Then follows layering. At the end stands integration: the money seemingly returns clean, for example as the purchase price for a property or as the salary of a shell company.

Layering is the decisive stage here. Without it, there would remain a straight line from the crime to the assets, and investigators could simply follow it. Only the many intermediate steps tear this line apart. That is why supervisory authorities, when monitoring banks, focus particularly on unusual chains of transfers.

For banks, a lot of money is at stake here. Anyone who overlooks layering risks fines in the billions. Several large European institutions have had to pay exactly for this reason in recent years. This explains why financial institutions invest large sums in monitoring software.

How the trail is broken apart

A common pattern is the chain of shell companies. These are companies that exist only on paper and have no real business activity. Company A transfers to Company B, which transfers to Company C, often via countries with weak disclosure requirements. Every border the money crosses makes tracing slower and more expensive for investigators.

In addition, amounts are broken up and then recombined. A million becomes fifty transfers of twenty thousand euros each, which later converge in another account. Purchases help too: securities, gold, luxury cars, or cryptocurrencies are acquired and sold again shortly afterward. The proceeds then look like a normal sales profit. In the case of cryptocurrencies, so-called mixers take on this task, that is, services that blend and redistribute payments from many users.

A common misconception is that layering is mainly about secrecy. The opposite is closer to the truth. The individual bookings are usually completely visible and formally correct. It is not the individual step that is suspicious, but the pattern formed by many steps. This is precisely why proving it is so laborious.

Pattern recognition in banks and in the news

Banks today run systems that check every transaction. Older programs work with fixed rules, for example: flag cash deposits over ten thousand euros. Such rules generate a great many false alarms, which staff have to sort out by hand. Newer systems use machine learning, that is, software that derives typical patterns from past cases on its own. They look not at individual payments but at entire networks of accounts and their connections.

In news articles, the term usually appears in the context of investigations and trials. It then describes how funds from corruption, drug trafficking, or sanctions evasion were shifted around. Providers of compliance software also advertise their ability to detect layering. Compliance here means a company’s obligation to comply with laws and regulatory rules.

An important distinction: in stock trading, layering means something completely different. There it refers to a prohibited technique in which traders place many fake orders in the order book and immediately cancel them again in order to influence the price. Which meaning is intended is almost always clear from the context of the text.
