What is Section 314(b)?
Section 314(b) of the USA PATRIOT Act allows financial institutions to share information with each other, under a legal safe harbor, to help identify and report suspected money laundering or terrorist financing activity.
Without this provision, privacy laws would generally prohibit one financial institution from disclosing customer information to another. Section 314(b) creates a protected channel for that sharing, provided institutions follow FinCEN's requirements.
Participation is voluntary. FinCEN strongly encourages it.
Context: 314(a) vs. 314(b)
Section 314 of the USA PATRIOT Act has two distinct parts that are often confused.
- Section 314(a) is mandatory. It requires financial institutions to respond to information requests from law enforcement, transmitted through FinCEN, when an agency is investigating suspected money laundering or terrorist activity. When FinCEN sends a 314(a) request, the receiving institution must search its records and respond.
- Section 314(b) is voluntary. It allows financial institutions to share information directly with each other, not just with law enforcement. A bank that suspects a customer of suspicious activity can reach out to another bank that has a relationship with the same customer to compare notes, without needing a law enforcement request to initiate the exchange.
The two provisions work alongside each other. A 314(b) exchange might surface information that leads to a Suspicious Activity Report (SAR), which is then reported to FinCEN under the institution's existing AML obligations.
The safe harbor
The reason Section 314(b) matters is the safe harbor it provides. Normally, sharing a customer's account details or transaction history with a third party would expose a financial institution to liability under privacy laws, including the Gramm-Leach-Bliley Act. Section 314(b) overrides that risk for participating institutions.
Under the safe harbor, a financial institution that shares information in compliance with Section 314(b) requirements cannot be held liable for the disclosure, or for failing to notify the subject of the disclosure, under any US federal or state law, regulation, or contract. This protection only applies when the institution has met all the required conditions.
How to participate
To participate in Section 314(b), a financial institution must:
- File a notice of intent to share with FinCEN. This is a straightforward filing, not an application process requiring approval
- Renew the notice annually to remain on the active participant list
- Before sharing information with another institution, verify that the other institution has also filed notice with FinCEN and is on the current participant list
- Share information only for permissible purposes: identifying and reporting suspected money laundering or terrorist activity, deciding whether to establish or maintain an account, or assisting with AML compliance
- Maintain policies and procedures to protect the security and confidentiality of shared information
FinCEN distributes the list of registered participants quarterly to enrolled institutions. If an institution does not appear on the latest list, the requesting institution can ask directly for a copy of FinCEN's confirmation of the other institution's notice.
Who is eligible
Eligibility is broader than many businesses realize. Any institution defined as a financial institution under 31 CFR 1010.540 can participate, which includes:
- Banks and credit unions
- Money service businesses, including money transmitters and currency exchangers
- Broker-dealers and investment companies
- Cryptocurrency exchanges and digital asset platforms subject to AML requirements
- Fintechs and payment service providers with AML obligations under FinCEN's regulations
Associations of financial institutions, such as industry groups whose membership consists entirely of eligible institutions, can also participate as a unit.
What can and cannot be shared
Under Section 314(b), institutions can share any information relevant to suspected money laundering or terrorist financing. In practice, a 314(b) request typically asks about:
- Whether the subject holds or has held an account
- Account type, opening date, and current status
- Transaction history or patterns relevant to the inquiry
- Any existing concerns or flags the receiving institution has on the account
There are firm limits on how the information can be used. It must be used only for the purposes listed above. It cannot be used for general competitive intelligence, credit decisions unrelated to AML, or any other purpose outside the scope of AML and counter-terrorist financing.
One important constraint: Section 314(b) does not allow institutions to reveal SAR filings.
SAR confidentiality is governed by separate regulations, and disclosing the existence of a SAR to another institution, even under 314(b), would violate those rules. Institutions can share underlying transaction data that informed a SAR, but not the fact that a SAR was filed. Institutions can, however, collaborate on joint SARs when the shared information warrants it.
Why it matters for payment operators
Criminals rarely concentrate activity at a single institution. They move funds across multiple accounts, entities, and payment channels to obscure the trail.
A single institution seeing only one segment of that activity may not have enough to recognize a pattern. Section 314(b) allows institutions to compare observations and connect pieces that would otherwise remain invisible.
For payment service providers and fintechs operating as money service businesses, practical reasons to participate include:
- Handling inbound inquiries cleanly: Platforms that process high volumes of transactions are frequently contacted by banks investigating suspicious flow of funds patterns. Being a registered participant means those requests can be handled through the protected channel rather than requiring a legal review each time
- Supporting banking relationships: Participation signals to bank partners and regulators that the institution takes AML seriously, which can be a factor in maintaining correspondent and sponsor bank relationships
- Catching patterns across institutions: A 314(b) exchange can surface connections that no single institution's data would reveal on its own, reducing the risk of processing activity that would have triggered a SAR if the full picture were visible
One thing it does not do is replace other compliance obligations. KYC, SAR filing, and OFAC screening all operate separately and still need to be in place. Section 314(b) is one layer in a complete AML program, not a substitute for one.
