Quick Answer
OFAC maintains the SDN list; firms screen customers, block property, file a blocking report within 10 business days, and file an annual report by September 30 for property blocked as of June 30. FinCEN administers the BSA, receiving CTRs, SARs, and information-sharing requests (14-day window), and permits voluntary FI-to-FI sharing. The SEC's BSA-compliance rule adds direct SEC enforcement.
OFAC and FinCEN are both bureaus of the U.S. Treasury, but they perform very different functions. The exam tests the distinction directly: OFAC = sanctions screening, FinCEN = BSA reporting. The SEC's BSA-compliance recordkeeping rule is the third leg of the stool that lets the SEC enforce a missed CTR or SAR alongside FinCEN.
Office of Foreign Assets Control (OFAC)
OFAC is a bureau of the U.S. Department of the Treasury that administers and enforces economic and trade sanctions based on U.S. foreign policy and national security goals. Sanctions can be:
- Country-based (comprehensive sanctions on Cuba, Iran, North Korea, Syria, Russia, and Venezuela's PDVSA, plus targeted Russia / Belarus measures)
- List-based (the SDN list; sectoral-sanctions identifications; non-SDN lists for specific programs)
- Activity-based (prohibitions on certain transactions regardless of counterparty)
OFAC sanctions apply to all U.S. persons (citizens, permanent residents, U.S. entities, anyone physically in the United States), which includes every domestic broker-dealer and every U.S. branch of a foreign broker-dealer.
The SDN List
OFAC maintains the Specially Designated Nationals and Blocked Persons List (SDN list): a public list of individuals and entities owned or controlled by, or acting for or on behalf of, sanctioned countries, plus terrorists, narcotics traffickers, weapons proliferators, and other targeted persons.
U.S. persons (including broker-dealers) are prohibited from dealing with SDNs and must:
- Block (freeze) any property of SDNs in their possession or control
- Reject transactions in which an SDN is a counterparty when no blockable interest exists
- Use risk-based screening of customers, beneficial owners, and counterparties at onboarding and as sanctions lists and transaction risks change; OFAC does not set one rescreening interval for every firm
Screening is typically performed by automated software comparing customer names, addresses, and identifying numbers against OFAC's regularly updated SDN list.
Exam Tip: Gotchas
- Block versus reject is OFAC vocabulary, not BSA. A blockable interest (for example, an SDN-owned account at the firm) requires the firm to freeze the property; a rejectable transaction (for example, an SDN counterparty in a cleared trade) requires the firm to refuse it. Both must be reported to OFAC.
- An opening screen cannot catch a later designation. A customer not on the SDN list when the account opens can be added later. Set rescreening procedures based on risk and account for list updates; OFAC does not mandate a universal weekly or monthly schedule.
Financial Crimes Enforcement Network (FinCEN)
FinCEN is a bureau of the U.S. Department of the Treasury that administers the Bank Secrecy Act. FinCEN's principal functions:
- Issues BSA regulations on behalf of the Treasury
- Receives and analyzes BSA filings: Currency Transaction Reports (CTRs), Suspicious Activity Reports (SARs), Foreign Bank Account Reports (FBARs), and Reports of Cash Payments Over $10,000 Received in a Trade or Business (Form 8300)
- Operates the BSA E-Filing System through which FIs submit reports
- Issues guidance on emerging typologies (cybercrime, ransomware, virtual currency, geographic targeting orders)
- Coordinates with law enforcement and other regulators
Exam Tip: Gotchas
- OFAC = sanctions screening (SDN list); FinCEN = BSA reporting (CTRs, SARs, law-enforcement information-sharing requests). Both are Treasury bureaus, but they serve different functions. The exam tests the distinction directly.
Law-Enforcement Information-Sharing Requests
The USA PATRIOT Act authorizes FinCEN to issue information requests to FIs on behalf of law-enforcement agencies investigating money laundering or terrorist financing. Mechanics:
- FinCEN sends the request electronically through the FinCEN Secure Information Sharing System
- The FI must search its records for the named persons of interest
- Search window: 2 weeks (14 calendar days) from the date of the request
- The FI reports back only positive matches; no match means no response is needed
- The FI must keep the request confidential from the named persons (a tipping-off prohibition similar to the SAR rule)
A law-enforcement information-sharing request is not an order to file a SAR, freeze accounts, or take any other action; it is purely a search-and-report obligation.
Exam Tip: Gotchas
- A FinCEN law-enforcement information-sharing request requires the firm to search records within 14 days and report positive matches; it does not require a SAR or any account action. The firm searches and reports back to FinCEN; it does not freeze the account or alert the customer.
- Law-enforcement information-sharing requests are government-driven; voluntary information sharing is FI-to-FI. Do not confuse the two.
Voluntary FI-to-FI Information Sharing
The USA PATRIOT Act also authorizes FIs to voluntarily share information with each other for anti-money laundering (AML) / counter-terrorism financing (CFT) purposes. Mechanics:
- The FI must file an annual notice with FinCEN before sharing
- Sharing must be in good faith, with another notice-registered FI
- Information shared is protected by safe harbor from civil liability
- Permitted purpose: identifying and reporting activities that may involve possible terrorist financing or money laundering
The notice is filed once per year and renewed annually. After filing, the FI may share information freely with other notice-registered FIs without seeking permission for each instance.
Exam Tip: Gotchas
- Voluntary FI-to-FI information sharing is opt-in; it requires advance notice to FinCEN. A firm that has not filed the notice cannot lawfully share AML information with another firm. The exam may ask whether two firms can compare notes on a suspicious customer; the answer requires both firms to be notice-registered first.
- The voluntary-sharing safe harbor protects the sharing FI, not the receiving FI's downstream use. Information shared in good faith does not authorize the recipient to tip off the customer.
The SEC's BSA-Compliance Recordkeeping Hook
The SEC's BSA-compliance recordkeeping rule requires every broker-dealer subject to the BSA to comply with BSA reporting, recordkeeping, and record-retention requirements as a condition of its SEC registration. The effect is to give the SEC its own enforcement hook for BSA failures: a missed CTR or SAR is not only a FinCEN violation; it is also a securities-law violation.
This means a single missed SAR can produce parallel enforcement actions:
- FinCEN for the BSA violation (civil monetary penalties under the BSA)
- FINRA for an AML-program-requirement violation (industry sanctions)
- SEC for a recordkeeping violation (separate civil penalties and administrative remedies)
Think of it this way: the SEC's BSA-compliance recordkeeping rule is the SEC's bridge into BSA enforcement. The BSA does not give the SEC direct enforcement authority over money laundering; making BSA compliance a condition of broker-dealer registration means any BSA violation is also a securities-law violation.
Exam Tip: Gotchas
- A single missed SAR can trigger FinCEN, FINRA, and SEC enforcement. The exam will sometimes ask which authority enforces the violation. The complete answer is all three: FinCEN under the BSA, FINRA under the AML-program requirement, and the SEC under its BSA-compliance recordkeeping rule.
- The SEC's BSA-compliance recordkeeping rule is the bridge into BSA enforcement. Without it, the SEC would have to wait for FinCEN to act. With it, the SEC can charge the firm directly.
What Should You Check on Exam Day?
- Can you distinguish an OFAC block (freeze an SDN's property) from a reject (refuse an SDN-counterparty transaction), and confirm both are reported to OFAC?
- Do you know a FinCEN law-enforcement information-sharing request gives the firm 14 calendar days to search records and report only positive matches?
- Can you distinguish OFAC's sanctions-screening function from FinCEN's Bank Secrecy Act reporting function, even though both are Treasury bureaus?
- Do you know a single missed Suspicious Activity Report can draw parallel enforcement from FinCEN, FINRA, and the SEC's BSA-compliance recordkeeping rule?
