Information-sharing requests (314(a))
Your notes
In simple terms / 01
What this means in plain language
Section 314(a) of the USA PATRIOT Act lets authorities ask financial institutions to search their records for named subjects of money-laundering or terrorism investigations. Firms search, report matches confidentially, and — unlike sanctions screening — freeze nothing.
Section 314(a) of the USA PATRIOT Act is an information-sharing mechanism that lets law enforcement, through the United States Financial Crimes Enforcement Network (FinCEN), ask financial institutions to search their records for named people and organisations under investigation for money laundering or terrorist financing. On a regular cycle, FinCEN sends participating institutions a confidential list of subjects. Each institution searches whether it holds, or recently held, accounts for those subjects or processed transactions for them, and reports back only whether it found a match — not the underlying account details. Law enforcement then follows up directly, through its own legal process, with the institutions that reported a match. Two features define the regime: it is confidential, so an institution must not tip off a subject that they have been named, and it is a search-and-report duty, not a freezing duty. Nothing is blocked or frozen simply because a name appears on a 314(a) request; the obligation is to look and to answer accurately.
Complete lesson / 02
Understand the full idea, step by step
Sometimes an investigator does not want a bank to freeze anything or stop a payment. They simply want to know: is this person known to you? Answering that question — accurately, confidentially, and without touching the account — is a control all its own, quite different from the sanctions screening it is easy to confuse it with.
Section 314(a) information request — the US information-sharing mechanism between authorities and institutions
Under the model set by Section 314(a) of the USA PATRIOT Act, the US Financial Crimes Enforcement Network (FinCEN), acting for investigators, sends participating institutions a confidential list of subjects suspected of money laundering or terrorist financing. Each institution searches its own records over defined look-back periods and reports whether a named subject is known to it. The exact cycle, response window, and look-back periods are set by FinCEN and change over time, so institutions follow current guidance rather than fixed numbers.
What the institution sends back
Where a search finds a match, the institution reports only that a match exists — identifying information and a point of contact — within the response window. It does not send statements, balances, or transaction detail in the response itself. If law enforcement wants those, it obtains them separately, through a subpoena or other legal process served on the institution. The 314(a) response is a pointer, not a disclosure of the account.
Section 314(b) voluntary sharing
A companion mechanism, 314(b), lets financial institutions share information *with each other* — voluntarily, under a protection from liability — to identify and report possible money laundering or terrorist financing. Where 314(a) is authority-to-institution, 314(b) is institution-to-institution. Both widen the picture beyond what any single firm can see, and both are bounded: the information is used for financial-crime purposes, not ordinary business decisions.
COMMON CONFUSION
“A 314(a) match means the bank must freeze the account, just like a sanctions hit.”
It means the opposite kind of action. A 314(a) request is confidential and backward-looking: find whether a relationship exists and tell the authority. Nothing is frozen, nothing is blocked, and the list is secret. Sanctions screening is public, forward-looking, and prohibitive: a confirmed match triggers a legal duty to freeze or reject and stop the payment. Freezing an account merely because a 314(a) subject was found would be a serious error.
| 314(a) request | Sanctions screening | |
|---|---|---|
| List | Confidential | Published |
| Direction in time | Backward-looking records search | Forward-looking, on every payment |
| Required action | Find and report to the authority | Freeze or reject — stop the value |
| Account effect | None | Value is immobilised |
WHAT IF — Someone proposes telling the customer, or using the request in a pricing or marketing decision.
What happens: Both are prohibited. The institution must not disclose to the subject or to anyone unnecessary that a request arrived or a match was found — tipping-off — and must not use the information for ordinary business decisions.
How it is handled: Access to the list is restricted, the systems holding it are secured, and use is limited to AML and reporting purposes. A positive match does not automatically require a suspicious-activity report; the institution applies its usual risk-based judgement, with the match as one input among several.
STRICTLY SPEAKING
Strictly speaking, this describes the United States regime. Other jurisdictions run their own information-request and information-sharing mechanisms under different rules, names, and protections. The shape recurs — an authority asks institutions to search and report, confidentially — but the specifics do not travel, so always work from the mechanism your jurisdiction actually operates.
FOR NOW, REMEMBER
- A 314(a)-style request asks institutions to search records for named subjects and report matches — confidentially.
- The response reports only that a match exists; account detail comes later, through separate legal process.
- 314(b) lets institutions share information with each other voluntarily, under liability protection.
- Unlike sanctions screening, a 314(a) request freezes nothing — confusing the two is a serious error.
TRY IT YOURSELF
Kabir's search finds that a named 314(a) subject holds an account at Meridian Bank. A colleague says to freeze the account at once. What is correct?
You have seen how reporting and information-sharing controls work around money laundering. The foundations topic steps back to the thing they all target: what money laundering is, and the stages controls are built to disrupt.
KEEP GOINGKey takeaways / 03
Three things to remember
- 01
Section 314(a) of the USA PATRIOT Act lets authorities, through FinCEN, ask financial institutions to search their records for named investigation subjects.
- 02
Institutions search current and recent accounts and transactions, then report only whether a match exists — not the account details, which law enforcement obtains later through its own legal process.
- 03
The regime is confidential and imposes no freeze: unlike a sanctions match, a 314(a) match blocks nothing and must not be disclosed to the subject.
Practical use cases / 04
Where you would use this
A financial-crime team receives a periodic 314(a) request, searches its account and transaction records for the named subjects, and records the search for audit.
A compliance officer reports a positive match back to FinCEN within the response window, providing only the identifying details and a point of contact.
An institution restricts access to 314(a) request lists and trains staff not to disclose a request to a customer, protecting the confidentiality the regime requires.
Worked example / 05
Put the idea into a real situation
Illustrative example: a fictional bank, Larkfield Savings, receives a 314(a) request from FinCEN naming a subject, 'Vincent Hale', with a date of birth and an address. Following its procedures, Larkfield searches its records for any current account, any account held during the preceding 12 months, and any transaction conducted in the previous 6 months matching the subject. It finds one account opened four months earlier. Larkfield reports the positive match to FinCEN within the 14-day response window, supplying only confirmation of the match and a contact for follow-up — it does not send statements, balances, or transaction histories, and it does not freeze the account or contact the customer. Law enforcement, now knowing where to look, serves its own legal process on Larkfield to obtain the detailed records. Throughout, Larkfield keeps the request confidential. Reporting a match does not by itself require filing a suspicious activity report; the bank applies its normal risk-based judgment to decide whether the underlying activity warrants one.
