What Does Structuring Mean and Why Is It Illegal?

Structuring in finance refers to breaking down a large financial transaction into smaller ones. This is done to avoid scrutiny from regulatory bodies and financial institutions. It is a serious financial crime, often linked to efforts to conceal the true nature or source of funds.

Defining Structuring

Structuring involves intentionally dividing a large cash transaction, such as a deposit or withdrawal, into multiple smaller amounts. Each transaction is designed to fall below the $10,000 reporting limit in the United States. For instance, someone with $40,000 might make four separate deposits of $9,900 each over several days or at different bank branches to avoid triggering a report. This fragmentation aims to circumvent financial institutions’ reporting requirements.

The intent behind structuring is to evade detection by financial institutions and government agencies. Those who engage in structuring often hide funds associated with illicit activities, such as money laundering, drug trafficking, or tax evasion. Even if funds were obtained legitimately, structuring to avoid reporting is illegal. Structuring can also involve breaking down purchases or other financial movements below a reporting threshold.

Reasons Structuring is Illegal

Structuring is a federal crime because it undermines the integrity of the financial system by impeding regulatory oversight. Federal laws, such as the Bank Secrecy Act (BSA), mandate that financial institutions report cash transactions exceeding $10,000 to the Financial Crimes Enforcement Network (FinCEN). The illegality of structuring stems from the intent to evade these reporting requirements, regardless of whether the money was acquired legally or illegally. This prohibition is codified under 31 U.S.C. § 5324.

Penalties for structuring can be severe. Individuals convicted can face fines up to $250,000 and imprisonment for up to five years. If structuring involves over $100,000 within twelve months or is linked to another criminal offense, penalties can escalate to fines up to $500,000 and imprisonment for up to ten years. Assets involved in structuring violations are subject to forfeiture, meaning the government can seize funds or property connected to the crime.

Detection of Structuring

Financial institutions play a central role in identifying and reporting structuring activities. They monitor customer transactions for suspicious patterns and file Suspicious Activity Reports (SARs) with FinCEN when they detect indicative behavior. These reports alert authorities to potential financial crimes, even if the institution cannot definitively prove a crime has occurred. Customers are not informed when a SAR is filed, ensuring investigations can proceed without alerting the suspected individual.

Several patterns can indicate structuring. These include frequent cash deposits or withdrawals just below the $10,000 reporting threshold, especially if conducted over a short period or across multiple branches or accounts. Unusual activity inconsistent with a customer’s known financial profile, such as a sudden increase in cash transactions, also raises red flags. Financial institutions increasingly leverage analytical tools, including machine learning algorithms, to identify complex patterns and anomalies.
