The Financial Action Task Force (FATF) is an inter-governmental body that sets standards and monitors compliance with anti-money laundering and counter-terrorist financing (AML/CFT) measures. The FATF conducts periodic mutual evaluations of its members and other jurisdictions to assess their level of implementation of the FATF Recommendations, which are the international AML/CFT standards. The FATF also identifies jurisdictions with strategic deficiencies in their AML/CFT regimes that pose a risk to the international financial system, and places them on two public lists: the High-Risk Jurisdictions subject to a Call for Action (also known as the black list) and the Jurisdictions under Increased Monitoring (also known as the grey list). The FATF works with these jurisdictions to address their deficiencies and monitors their progress through regular follow-up reports and on-site visits. The FATF may remove a jurisdiction from the list if it has made sufficient and sustainable progress in implementing the required reforms and has effectively addressed the identified strategic deficiencies. Therefore, receiving a favorable mutual evaluation is the most likely reason for the FATF to remove a jurisdiction from the list, as it indicates that the jurisdiction has met the FATF standards and has a robust AML/CFT system in place.
Conducting successful annual self-assessments, entering into a mutual legal assistance treaty, or joining the Wolfsberg Group are not sufficient reasons for the FATF to remove a jurisdiction from the list, as they do not necessarily reflect the overall compliance with the FATF Recommendations or the resolution of the strategic deficiencies. Moreover, the Wolfsberg Group is a private association of global banks that develops guidance and best practices for the financial sector on AML/CFT issues, and is not affiliated with the FATF.

The scenario described in the question presents several indicators of potential money laundering through real estate, which the broker should be aware of and report accordingly. The most relevant red flags are:
Value: The student wants to buy a home that is overvalued, meaning that the asking price is higher than the market value or the appraisal value of the property. This could indicate that the student is trying to launder a large amount of illicit funds in one transaction, or that the seller is colluding with the student to inflate the price and receive a kickback. Overvaluing or undervaluing properties is a common technique used by money launderers to manipulate the price of real estate and conceal the source or destination of their funds12.
Inconsistency: The student's behavior and profile are inconsistent with the typical characteristics of a legitimate home buyer. The student cancels the viewing of the home at the last minute due to illness, which could suggest a lack of interest or a pretext to avoid scrutiny. The student also wants to buy an expensive home despite being a student, which could indicate a discrepancy between the student's income and the source of funds. Moreover, the student disregards the broker's objections to the asking price, which could imply that the student is not concerned about the value or quality of the property, but rather the amount of money that can be laundered through it34.
Transaction speed: The student wants to quickly buy the home, which could indicate a sense of urgency or pressure to move the illicit funds before they are detected or seized by the authorities. Money launderers often use fast transactions to avoid raising suspicion or leaving a paper trail. Transaction speed is especially relevant when combined with other red flags, such as cash payments, anonymous buyers, or overvalued properties5 .

The anti-money laundering officer should advise the account-opening officer to verify the identity of all the partners as an initial step. This is because opening a bank account for an offshore company with multiple owners from different jurisdictions poses a high risk of money laundering and terrorist financing. Therefore, the bank should apply enhanced due diligence measures to ensure that the offshore company and its owners are legitimate and not involved in any criminal activities. One of the key measures is to verify the identity of all the partners, not just the one who presents the power of attorney. This will help the bank to establish the beneficial ownership and control structure of the offshore company, as well as to detect any possible fraud, forgery, or coercion in the power of attorney document. The bank should also verify the authenticity and validity of the power of attorney, and the scope and purpose of the authority granted to the partner who requests the account opening.
The other options are less important or irrelevant as initial steps. Verifying the source of the deposit is also a part of the enhanced due diligence process, but it should be done after verifying the identity of the partners and the offshore company. Filing a suspicious transaction report with the appropriate Financial Intelligence Unit or the Egmont Group is a possible action that the bank may take if it detects any indicators of money laundering or terrorist financing in the account opening process, but it is not an initial step. The Egmont Group is an international network of Financial Intelligence Units that facilitates information exchange and cooperation, but it is not a reporting authority.

According to the Certified Anti-Money Laundering Specialist (CAMS) Manual [1], 6th edition, financial entities that violate Anti-Money Laundering (AML) laws can face several reputational risks such as loss of high-profile customers, seizure of assets, increased audit costs to monitor behavior, and monetary penalties.
For example, the US Treasury's Financial Crimes Enforcement Network (FinCEN) imposes civil money penalties on "persons who willfully violate, attempt to violate, conspire to violate, or cause any violation of any provision of the Bank Secrecy Act or its implementing regulations." (CAMS Manual, 6th edition, page
26).

Economic sanctions are penalties imposed by one or more countries against another country, group, or individual for violating international norms or threatening national interests1. The ultimate goal of economic sanctions is to protect national security by changing the behavior or policies of the target, or by weakening its capabilities or resources2. Sanctions can be used to advance various foreign policy objectives, such as counterterrorism, nonproliferation, democracy promotion, human rights protection, conflict resolution, and cybersecurity1. Sanctions can take different forms, such as travel bans, asset freezes, trade embargoes, arms restrictions, and aid reductions1. Sanctions can be applied unilaterally by one country, or multilaterally by a coalition of countries or an international organization, such as the United Nations or the European Union1.
