The Financial Action Task Force (FATF) Recommendation that should cause an anti-money laundering specialist the most concern is B: Financial institutions should not keep anonymous accounts. This is because anonymous accounts are accounts that are opened or maintained without verifying the identity of the customer or the beneficial owner, or with fictitious or incomplete information. Anonymous accounts pose a high risk of money laundering and terrorist financing, as they can be used to conceal the origin, destination, and purpose of illicit funds, and to evade the detection and reporting of suspicious transactions. Therefore, the FATF Recommendation 10 requires financialinstitutions to identify and verify the identity of their customers and the beneficial owners, and to prohibit the opening or maintaining of anonymous accounts or accounts in obviously fictitious names1.
The other options are also FATF Recommendations, but they are less relevant or applicable to the scenario.
Option A: Financial institutions should not warn their customers when information relating to them is being reported to the competent authorities, is the FATF Recommendation 21, which aims to prevent tipping-off, i.
e., alerting the customer that they are being investigated or reported for money laundering or terrorist financing. However, this does not directly address the issue of identity verification or anonymous accounts2.
Option C: Financial institutions should maintain all necessary suspicious transaction report records on transactions, both domestic and international, for at least 5 years, is the FATF Recommendation 11, which aims to ensure that financial institutions have adequate and consistent records of their customers and transactions, and that these records are available to the competent authorities when needed. However, this does not prevent the opening or maintaining of anonymous accounts in the first place3. Option D: If financial institutions suspect that funds stem from criminal activity,they should be required to close the account, is not a FATF Recommendation, but rather a possible action that financial institutions may take in accordance with their risk assessment and policies. However, the FATF does not mandate or recommend the closure of accounts as a general rule, and advises that financial institutions should consult with the competent authorities before taking such action, as it may alert the customer or compromise the investigation4.

An automated transaction monitoring system is a tool that analyzes transactions and customer behavior for signs of money laundering or other financial crimes, and generates alerts when suspicious or unusual activity is detected. The system relies on a set of rules and parameters that define what constitutes normal and abnormal transactions, based on the risk profile and business nature of the financial institution or business.
These rules and parameters need to be periodically reviewed and updated to ensure that they are effective and compliant with the latest regulations and best practices.
One of the factors that would most likely result in a change in the monitoring system parameters is when the national Financial intelligence Unit (FIU) issues new risk indicators. The FIU is a central authority that collects, analyzes, and disseminates financial intelligence related to money laundering, terrorist financing, and other financial crimes. The FIU also provides guidance and feedback to financial institutions and businesses on how to comply with their anti-money laundering (AML) obligations and improve their transaction monitoring systems. The FIU may issue new risk indicators based on its analysis of emerging trends, typologies, and threats in the financial sector, or based on international standards and recommendations.
These risk indicators are intended to help financial institutions and businesses identify and report suspicious transactions more effectively and efficiently.
Therefore, when the FIU issues new risk indicators, the financial institution or business should review its existing monitoring system parameters and adjust them accordingly to reflect the new risks and scenarios. For example, the FIU may issue new risk indicators related to the use of cryptocurrencies, virtual assets, or online platforms for money laundering or terrorist financing. In that case, the financial institution or business should update its monitoring system parameters to include new rules, thresholds, or patterns that capture these activities and generate alerts for further investigation.

The Asian/Pacific Financial Action Task Force-Style Regional Body (APG) helps its members implement recommendations from the FATF by facilitating the adoption and implementation of internationally accepted AML measures by member jurisdictions (CAMS Manual, 6th Edition, Page 22). The APG also encourages cooperative AML efforts in the region, which can include information-sharing and mutual evaluations to assess member compliance with FATF recommendations (CAMS Manual, 6th Edition, Page 25). Therefore, options C and D are the correct answers.

An institution should focus on the appropriateness of having a centralized review of suspicious transactions and recommendations to file an STR to ensure consistency. This is because a centralized review process can help to avoid duplication, inconsistency, or omission of STRs, as well as to ensure compliance with regulatory requirements and internal policies. A centralized review process can also facilitate the analysis of trends, patterns, and typologies of suspicious transactions across the institution, and enable the communication and coordination with relevant stakeholders, such as law enforcement, regulators, or other financial institutions.

A customer's account appears to function as a funnel account whereby cash deposits occur in cities/states where the customer does not reside or conduct business. Frequently, in the case of funnel accounts, the funds are quickly withdrawn (same day) after the deposits are made
