A predicate offense is the underlying crime that generates the money later laundered, such as fraud, drug trafficking, corruption, or tax evasion. In most regimes it is a required element: without an underlying crime, there is nothing to charge as money laundering.
What is a predicate offense, in plain English?
A predicate offense is the original crime that produced the money. Money laundering does not create wealth; it disguises wealth that came from something illegal. That something, the fraud, the trafficking, the bribe, the tax evasion, is the predicate. It is the source of the dirty money that everything else tries to clean.
In most legal regimes, a predicate offense is a required element to charge laundering at all. You cannot launder proceeds that no crime generated, so prosecutors have to connect the funds to some underlying criminal conduct. Jurisdictions publish lists or categories of offenses that qualify, and the money laundering charge attaches to their proceeds.
For an AML team, you rarely need to prove the predicate to act, but identifying or reasonably inferring it strengthens your case. A suspicious activity report that can point to a likely underlying crime, even without naming it precisely, is far more actionable than one that just says the money looks odd.
Predicate offense versus laundering
What changes | Predicate offense | Money laundering |
What it is | The crime that earns the money | Disguising where the money came from |
Example | Fraud, trafficking, corruption | Structuring, shells, trade schemes |
Produces | The dirty proceeds | Clean-looking funds or assets |
Legal role | Usually required for a laundering charge | A separate offense of concealment |
Operator focus | Infer it to strengthen the report | Detect the concealment behavior |
Who is involved?
Who | Their role |
The predicate offender | Commits the underlying crime that generates the proceeds needing laundering. |
The launderer | Disguises those proceeds, sometimes the same person, sometimes a third party. |
Analysts and MLROs | Infer the likely predicate to sharpen suspicious activity report narratives. |
Prosecutors | Must usually establish a qualifying predicate to bring a money laundering charge. |
What it looks like in practice
In practice
An analyst reviews a business account receiving frequent inbound payments from many individuals, each tagged as an invoice, followed by rapid transfers offshore. The customer is a small IT consultancy with no plausible reason for that volume of unrelated payers.
The pattern matches known investment-scam proceeds. The analyst cannot prove the fraud, but the behavior lets them reasonably infer the likely predicate, fraud against the many payers, and say so in the report. Naming that probable underlying crime turns a vague concern into a narrative investigators can act on, and supports the suspicion of illicit origin.
Why it matters to operators
The predicate offense is the legal hook that makes laundering chargeable, so cases often rise or fall on whether a qualifying underlying crime can be shown. That means the quality of your reporting improves when you can point to a likely predicate, even by inference, rather than simply flagging unexplained money.
It also drives real jurisdictional complexity. Regimes differ on which offenses qualify and whether a crime committed abroad counts as a valid predicate at home. Those differences shape both what you must report and whether a case can be prosecuted, so operators working across borders need to know that a flow lawful to ignore in one place may be a reportable, chargeable predicate in another.
What to watch in the data
- Crime-shaped flows. Patterns matching known typologies, such as scam proceeds, trafficking cash, or corruption payments.
- Many unrelated payers. Inbound funds from numerous unconnected individuals, a common fraud-proceeds signature.
- High-risk nexus. Counterparties, sectors, or regions associated with corruption, sanctions evasion, or trafficking.
- Source that does not add up. Funds with no lawful explanation that point toward an unnamed underlying offense.
- Cross-border qualification. Foreign conduct that may or may not count as a predicate depending on the jurisdiction.
Quick questions
Do you have to prove the predicate to file a report?
No. You can and should report suspicion of illicit origin without proving the underlying crime. Inferring a likely predicate strengthens the narrative, but the standard for reporting is suspicion, not proof.
What crimes commonly count as predicates?
Fraud, drug trafficking, corruption and bribery, tax evasion, human trafficking, and many others. Most regimes publish qualifying categories, and serious offenses that generate proceeds almost always qualify.
Does a foreign crime count as a predicate?
It depends on the jurisdiction. Some regimes recognize foreign predicate offenses, others only if the conduct would also be a crime at home. This dual-criminality question directly affects whether a case can be charged.
Can there be laundering without a predicate?
In most regimes, no; the proceeds have to come from some underlying crime. A few systems allow standalone laundering charges without proving the specific predicate, but a criminal source is still required in concept.
Why does inferring the predicate help?
A report that identifies a probable underlying crime gives investigators a direction and supports the suspicion of illicit origin. It turns unexplained money into a workable lead rather than a generic alert.
How does it relate to self-laundering?
Self-laundering is when the predicate offender also launders their own proceeds. The predicate is the crime that earned the money; self-laundering is one arrangement of who does the cleaning afterward.
