What Is Structuring in Banking and Why Is It Illegal?

Structuring in banking refers to the practice of breaking down financial transactions, typically cash deposits or withdrawals, into smaller amounts. The primary goal of this division is to prevent financial institutions from filing mandatory reports to government authorities. This practice undermines the transparency of the financial system and hinders efforts to track the movement of money.

Cash Transaction Reporting Requirements

Financial institutions in the United States operate under specific regulations requiring the reporting of certain cash transactions. The Bank Secrecy Act (BSA) mandates that banks and other financial entities file a Currency Transaction Report (CTR) for any cash transaction exceeding $10,000. This threshold applies to single transactions or multiple related transactions conducted by or on behalf of the same person within a single business day. These reports are a fundamental tool in the government’s efforts to combat money laundering and the financing of terrorism.

The Financial Crimes Enforcement Network (FinCEN) is the primary recipient of these CTRs. The reporting requirement provides transparency into large cash movements, and filing a CTR does not imply wrongdoing. These reports serve as an information-gathering mechanism to help financial regulators and law enforcement agencies identify and investigate suspicious financial activities. A CTR includes details about the customer and the transaction, such as name, address, identification, amount, and purpose.

Methods of Structuring Transactions

Individuals attempt to structure transactions by dividing what would otherwise be a single large cash transaction into multiple smaller ones to avoid the $10,000 reporting threshold. A common method involves making several cash deposits, each under $10,000, over a period of time. For example, a person with $20,000 in cash might deposit $9,000 on one day and $9,500 a few days later, hoping to evade reporting.

Another tactic includes conducting transactions at different branches of the same bank or even across multiple financial institutions. Some individuals might use different accounts, including those belonging to family members or associates, to spread out deposits and obscure the total amount. Similarly, large cash withdrawals can be structured by taking out multiple smaller amounts instead of one lump sum. The defining element that transforms these actions into illegal structuring is the intent to evade the mandatory reporting requirements, rather than merely the act of breaking up transactions. The pattern of these fragmented transactions, often occurring just below the reporting limit, frequently signals potential structuring activity to financial institutions.

Legal Ramifications of Structuring

Structuring cash transactions to evade federal reporting requirements is a serious federal crime, regardless of whether the funds were obtained lawfully or through illicit means. Penalties for a structuring conviction can be substantial, including significant fines and imprisonment. Individuals may face fines up to $250,000 and prison sentences of up to five years.

In cases where the structured transactions total over $100,000 within a 12-month period or are connected to other illegal activities, the penalties can be more severe, potentially leading to longer prison sentences, sometimes up to ten years, and doubled fines. Federal law, 31 U.S.C. § 5324, makes it a crime to structure or attempt to structure any transaction with a financial institution for the purpose of evading reporting requirements. A critical component for prosecution is demonstrating the individual’s intent to evade the reporting obligation. The government can also seize and forfeit any property involved in a structuring violation.

Financial Institution Detection Measures

Banks and other financial institutions employ various methods to identify and prevent structuring activities. Bank employees receive training to recognize suspicious transaction patterns. These patterns might include frequent cash deposits or withdrawals just below the $10,000 CTR threshold, or multiple transactions occurring on the same day or over a short period.

Beyond human observation, financial institutions utilize sophisticated software and data analytics to monitor transaction activity. These systems flag unusual patterns, identify sequences of transactions that may indicate structuring, and compare current activity against a customer’s historical behavior. When a financial institution suspects structuring or any other illegal financial activity, it is legally obligated to file a Suspicious Activity Report (SAR) with FinCEN. SARs enable banks to report potential criminal violations to law enforcement agencies.
