Dirty money enters, hides, then comes back clean. Splitting deposits to stay under the line is a crime on its own.
Three stages, and the offense hiding inside the first
Money laundering runs in three stages and questions almost always ask which one a described act belongs to. Placement is getting criminal proceeds into the financial system in the first place: depositing cash, buying money orders, or opening an account with dirty money. It is where cash is physically handed over, so currency reporting applies there.

Layering is the shuffling that follows. Money moves between accounts, across borders, in and out of securities, through shell companies, in patterns designed to make the trail impossible to follow. Nothing is bought or enjoyed at this stage; the purpose is only distance. A pattern of transfers with no economic sense is the classic layering signal.
Integration is the money coming back as apparently legitimate wealth: a property purchase, a business investment, a loan to oneself from an offshore company. By this point the funds look ordinary, which is why detection has to happen earlier. Firms are required to collect identifying information before an account is opened and to verify it within a reasonable time before or after opening.
Two other checks run alongside. A firm screens customers against the Specially Designated Nationals and Blocked Persons List kept by OFAC: it may not open an account for a blocked person, must first decide carefully whether a name alert is a true match, and must block property of a blocked person in its possession or control and report it to OFAC within ten business days. And under section 314 of the USA PATRIOT Act, when FinCEN sends a request naming a suspect (314(a)), a firm must search its records, report any match and keep the request confidential, while sharing information with another firm (314(b)) is voluntary and needs a notice to FinCEN, renewed each year, and a check that the other firm has filed one too.
Structuring is not a stage; it is a separate criminal offense usually committed during placement. Deliberately breaking a cash transaction into smaller amounts to keep each one under the currency reporting threshold is illegal in itself, whatever the source of the money. A customer who asks how to stay under the line has told you enough, and a customer whose funds are entirely legitimate is still committing an offense by splitting them.
Every member firm must have an anti-money laundering program, and FINRA Rule 3310 sets its minimum elements. The program must be in writing and approved in writing by a member of senior management. It must include policies and procedures reasonably expected to detect and cause the reporting of suspicious transactions, and internal controls to comply with the Bank Secrecy Act. It must provide for independent testing, annually for firms that hold customer accounts, and designate an AML compliance person responsible for day-to-day operations, identified to FINRA. It must provide ongoing training for appropriate personnel, and include risk-based procedures for ongoing customer due diligence.
Knowing who the customer is
The customer identification program has a fixed minimum. Before opening the account the firm obtains the customer’s name, date of birth for an individual, address and an identification number. Documents such as a driver’s license, or references from other financial institutions, are ways to verify them, not substitutes for them. If the firm cannot form a reasonable belief that it knows who the customer is, its written procedures say when not to open the account, when to close it and when to file a suspicious activity report.

The program also checks whether the customer appears on any government list of known or suspected terrorists or terrorist organizations, and it gives customers notice that the firm is asking for information to verify their identities. A firm may post that notice in its office or on its website, or put it on the account application.

Sanctions are a different duty from reporting
Reporting and blocking are not the same obligation. A suspicious activity report tells the government about a transaction and the transaction may still proceed; a sanctions match stops the property where it stands.

US persons must generally block all property and interests in property of persons on the Specially Designated Nationals and Blocked Persons List that are within US territory or within the possession or control of a US person, and must report the blocking. The list is administered by the Office of Foreign Assets Control, a Treasury bureau, and a name match is a reason to stop and check rather than a reason to close the account quietly.
The three stages in order
- Placement
Cash enters the financial system
- Layering
Transfers obscure where it came from
- Integration
It re-emerges as ordinary wealth
Try it: Assign a stage to four acts without looking back: a customer buys a holiday home with funds wired from three offshore companies; a customer deposits a sports bag of cash; a customer sends money between six accounts in four countries in a week; a customer asks whether several smaller deposits would attract less attention. One of the four is not a stage at all, and naming what it is instead is the point of the exercise.

Worked example
A new customer deposits $9,400 in cash on a Monday and $9,200 on the Wednesday, and mentions that a single deposit would have triggered paperwork he would rather avoid.
- Take the amounts first. Each deposit sits below the currency reporting threshold, and together they exceed it, which is the pattern the rule is written to catch.
- Now take the statement. He has explained that the split was chosen to avoid a report, which supplies the intention that turns two ordinary deposits into structuring.
- The source of the money is not the question. Even if he can document every dollar, deliberately breaking the transaction to evade the report is itself an offense.
- The stage is placement, because this is cash entering the financial system, and structuring is the offense committed in the course of it.
- The representative escalates internally to the firm’s anti-money-laundering officer and says nothing to the customer about what is being reported.

The closest contrast
Structuring: splitting deposits.
Layering: shuffling through accounts.
The distinction decides which label a scenario earns. Structuring is about the size of each transaction against a reporting threshold; layering is about the number and complexity of the movements once the money is already inside the system.
Summary
- Placement puts criminal proceeds into the system; layering obscures the trail; integration returns the money as ordinary wealth.
- Structuring is a separate offense, committed by splitting a transaction to avoid a report.
- The legality of the underlying funds is no defense to structuring.
- Name, date of birth, address and an identification number are collected before the account is opened; identity is verified within a reasonable time before or after, a failed check follows the firm’s written procedures, and list screening is not left until a problem appears.
