Suspicious Activity Reporting Obligations

Why Suspicious Activity Reporting Obligations Matter

Suspicious activity reporting is the point where an institution's entire anti-financial crime (AFC) program converts into actionable intelligence for law enforcement. Everything upstream (customer due diligence, transaction monitoring, sanctions screening, employee training) ultimately exists to detect and escalate suspicious behaviour, and the Suspicious Activity Report (SAR) or Suspicious Transaction Report (STR) is the formal output of that effort. For the CAMS exam, this topic sits inside the AFC Program Governance and Risk Management domain because filing decisions, confidentiality, record-keeping, and escalation processes are core governance responsibilities that regulators scrutinise heavily. Failures in this area (late filings, failure to file, tipping off, or weak narratives) are among the most common findings in enforcement actions and can lead to significant civil penalties, criminal exposure for individuals, and reputational damage. Understanding the obligations is therefore not just an exam requirement; it is a professional necessity.

What Is a Suspicious Activity Report?

A SAR (the US term) or STR (the term used in the FATF Recommendations and many other jurisdictions) is a confidential report submitted by a financial institution or designated non-financial business or profession (DNFBP) to its national Financial Intelligence Unit (FIU) when it knows, suspects, or has reasonable grounds to suspect that funds are the proceeds of criminal activity, are related to terrorist financing, or that a transaction has no apparent lawful purpose or deviates from the expected pattern for that customer.

Key international framework points:
• FATF Recommendation 20 requires that if a financial institution suspects or has reasonable grounds to suspect that funds are the proceeds of criminal activity or related to terrorist financing, it must report promptly to the FIU. Reporting should be required regardless of the amount involved and should include attempted transactions.
• FATF Recommendation 21 provides that institutions, their directors, officers, and employees are protected from criminal and civil liability for breach of confidentiality when reporting in good faith, and prohibits tipping off the customer that a report has been filed.
• FATF Recommendation 23 extends reporting obligations to DNFBPs such as lawyers, accountants, real estate agents, dealers in precious metals and stones, and trust and company service providers.
• FATF Recommendation 29 establishes the role of the FIU as the national centre for receipt and analysis of STRs and other information relevant to money laundering and terrorist financing.

In the United States, the obligation derives from the Bank Secrecy Act (BSA) and its implementing regulations administered by FinCEN. In the European Union, the Anti-Money Laundering Directives (and the forthcoming AML Regulation and AMLA) require reporting to national FIUs. The United Kingdom uses the term Suspicious Activity Report and requires filing with the National Crime Agency (NCA), with a distinct Defence Against Money Laundering (DAML) request mechanism for consent to proceed with a transaction.

Core Concepts You Must Know

1. The reporting standard. Most regimes use a standard of knowledge, suspicion, or reasonable grounds to suspect. This is a low threshold; it does not require proof of a crime, identification of a specific predicate offence, or certainty. In the US, a SAR is required when an institution knows, suspects, or has reason to suspect that a transaction involves funds from illegal activity, is designed to evade BSA requirements (structuring), has no business or apparent lawful purpose, or involves the use of the institution to facilitate criminal activity.

2. Thresholds and amounts. FATF guidance calls for reporting regardless of amount. In the US, however, regulatory thresholds apply for mandatory filing: generally $5,000 for banks and most financial institutions where a suspect can be identified, $25,000 where no suspect is identified, and $2,000 for money services businesses. Insider abuse by an employee or director must be reported regardless of amount. Institutions may always file voluntarily below these thresholds. The exam frequently tests these figures and the distinction between mandatory and voluntary filing.

3. Attempted transactions. Reporting obligations cover transactions that were attempted but not completed, including those the institution declined. A customer who walks away when asked for identification can still trigger a filing.

4. Timing. In the US, a SAR must be filed within 30 calendar days of the initial detection of facts that may constitute a basis for filing. If no suspect is identified, the institution may delay up to an additional 30 days (60 days total) to identify a suspect, but never beyond 60 days. Situations requiring immediate attention, such as ongoing money laundering schemes or terrorist financing, must also be reported by telephone to law enforcement immediately, in addition to filing the SAR. Other jurisdictions typically require filing promptly or without delay once suspicion is formed.

5. Continuing activity. If suspicious activity continues after the initial SAR, institutions are expected to file continuing activity reports, in the US typically every 90 days after the previous filing, with a 120-day review cycle. The decision to retain or exit a customer after repeated SARs is a governance matter and should be documented.

6. Confidentiality and tipping off. A SAR and any information that would reveal its existence are strictly confidential. Institutions may not disclose a SAR or its contents to the subject or to any third party except as permitted by law (for example, to the FIU, appropriate law enforcement, supervisory regulators, or within the corporate family where permitted). Tipping off is a criminal offence in most jurisdictions. Employees who receive a subpoena or request for SAR information must decline to produce it and notify FinCEN or the relevant FIU. Note the distinction: the institution may share the underlying transactional information but not the fact that a SAR was filed.

7. Safe harbour. Reporting institutions and their personnel are protected from civil liability for disclosures made in good faith, even if the suspicion later proves unfounded. This protection encourages filing and should be remembered when a scenario asks whether an institution risks liability for reporting a customer.

8. Record retention. SARs and supporting documentation must be retained, in the US for five years from the date of filing, and must be made available to FinCEN, law enforcement, and the appropriate regulator upon request. Supporting documentation is considered part of the SAR and is also confidential.

9. The SAR narrative. The narrative is the most important part of the report. It should clearly answer the who, what, when, where, why, and how of the suspicious activity, explaining why the institution found the activity suspicious, in chronological order, using plain language, and avoiding unsupported conclusions. A poor narrative undermines the value of the filing to investigators.

10. Board and senior management reporting. In the US, the board of directors (or a designated committee) must be notified of SAR filings. The level of detail may be summarised, but regulators expect evidence that governance bodies are informed about the volume and nature of suspicious activity.

How the Reporting Process Works in Practice

Step 1: Detection. Red flags are identified through automated transaction monitoring alerts, employee referrals, sanctions or negative news hits, law enforcement inquiries (such as 314(a) requests in the US), customer due diligence reviews, or subpoenas. Any employee may detect suspicious activity; the obligation to escalate internally belongs to everyone.

Step 2: Escalation. The matter is referred to the compliance or financial intelligence function. Institutions should have a documented, confidential internal escalation process. Front-line staff must not confront or alert the customer.

Step 3: Investigation. Analysts review account activity, KYC information, expected versus actual behaviour, related parties, source of funds, and open-source information. The goal is to determine whether a reasonable explanation exists or whether the activity remains unexplained. The case file, including the rationale for the decision, must be documented whether or not a report is filed.

Step 4: Decision. The designated officer, often the Money Laundering Reporting Officer (MLRO) or BSA Officer, decides whether to file. A decision not to file must be documented with reasoning. Many regulators specifically examine these no-file decisions.

Step 5: Filing. The report is submitted electronically to the FIU (for example, via the BSA E-Filing System to FinCEN). Information must be complete and accurate; the narrative should be clear and well organised.

Step 6: Post-filing actions. The institution continues to monitor the customer, considers enhanced due diligence or account closure, assesses whether continuing activity reports are warranted, responds to any follow-up requests from the FIU or law enforcement, and preserves records. The board or senior management is informed through periodic reporting.

Common Pitfalls Regulators Identify

• Late filings caused by alert backlogs or unclear date of initial detection tracking.
• Failure to file on attempted transactions or on activity below thresholds that still appeared suspicious.
• Weak or template narratives that do not explain why the activity is suspicious.
• Tipping off through careless communication with the customer or through account closure letters that reference suspicious activity.
• Inconsistent treatment of similar cases, indicating a lack of documented decision criteria.
• Lack of board reporting or management information about SAR trends.
• Failure to maintain or produce supporting documentation.

Exam Tips: Answering Questions on Suspicious Activity Reporting Obligations

Tip 1: Apply the low threshold. When a scenario describes unusual behaviour with no reasonable explanation, the correct answer is almost always to escalate internally and consider filing. You do not need proof of a crime or identification of the predicate offence. Answer choices that suggest waiting for more evidence, asking the customer to explain the suspected crime, or confirming illegality first are usually wrong.

Tip 2: Never tip off. Any option that involves telling the customer a report has been filed, warning them that their activity looks suspicious, or including SAR information in a letter or conversation is incorrect. Equally, any option that involves providing a SAR to a third party, including auditors in most cases or a subpoena-issuing attorney, without legal authority is wrong. The right response to a subpoena for a SAR is to refuse and notify the FIU.

Tip 3: Distinguish escalation from decision. Front-line employees should report suspicion internally to compliance; they do not decide whether to file with the FIU and they should not conduct their own investigation that could alert the customer. Questions about what should the teller or relationship manager do are usually answered by internal escalation.

Tip 4: Know the US timing and threshold numbers. Memorise 30 days from initial detection, up to 60 days if no suspect is identified, immediate telephone notification for urgent matters, 90-day continuing activity filings, $5,000 and $25,000 thresholds for banks, $2,000 for MSBs, insider abuse at any amount, and five-year retention. These appear as direct recall questions and as details hidden within scenarios.

Tip 5: Remember attempted transactions and declined business. If a prospective customer abandons an application when asked for identification, or a transaction is refused, this can still require a report. Options that assume no report is needed because no transaction occurred are typically incorrect.

Tip 6: Document everything, including decisions not to file. If a question asks what the compliance officer should do after concluding that a report is not warranted, the answer involves documenting the investigation and rationale. Undocumented no-file decisions are a classic regulatory finding.

Tip 7: Favour the FATF-aligned principle in international scenarios. When a question is not jurisdiction-specific, think in FATF terms: report promptly, report regardless of amount, protect confidentiality, rely on the safe harbour, and report to the FIU rather than directly to police as the primary channel.

Tip 8: Recognise the role of the narrative. Questions about report quality are answered by selecting options that emphasise a clear, chronological, factual narrative explaining why the activity is suspicious, with the who, what, when, where, why, and how. Avoid options suggesting vague summaries or attaching documents instead of writing a narrative.

Tip 9: Link reporting to governance. Expect questions tying SARs to board oversight, management information, independent testing, and risk assessment updates. The best answers show that suspicious activity data feeds back into the risk-based approach, informs customer risk ratings, and is reported to senior management.

Tip 10: Watch for safe harbour logic. If an answer choice suggests the institution should avoid filing because the customer might sue for defamation or breach of confidentiality, it is wrong; good-faith reporting is legally protected.

Tip 11: Read for the single best action. CAMS questions often present several reasonable-sounding steps. Choose the action that is required first or that most directly satisfies the legal obligation, typically escalating to the MLRO or BSA Officer, filing within the regulatory window, and maintaining confidentiality, rather than peripheral steps like updating marketing records or closing the account immediately without analysis.

Quick Revision Summary

• Obligation: report known or suspected proceeds of crime, terrorist financing, or unexplained activity to the FIU.
• Standard: knowledge, suspicion, or reasonable grounds; no proof required.
• Scope: completed and attempted transactions; applies to financial institutions and DNFBPs.
• Timing: promptly; in the US, 30 days (up to 60 if no suspect), immediate call for urgent cases, continuing reports every 90 days.
• Confidentiality: no tipping off; SARs and supporting documents may not be disclosed except as permitted by law.
• Protection: safe harbour for good-faith reporting.
• Records: retain for five years with supporting documentation.
