According to the FATF Recommendation 40, which sets the standards for international cooperation in relation to money laundering, associated predicate offences and terrorist financing, countries should ensure that exchanged information is used only for the purpose for which it was sought or provided, and that any dissemination or use of the information beyond the original scope is subject to prior authorization by the requested competent authority. Moreover, countries should have safeguards in place to ensure that the information exchanged is protected in a manner that is consistent with the way they protect their own information of a similar nature. One of the possible safeguards is to require the use of non-disclosure agreements or other legal instruments to prevent unauthorized access or disclosure of the exchanged information.

The three statements from the procedure that are in line with Wolfsberg are:
* B. The responsible private banker must establish the identity of a holder of general powers over an account (e.g. a signatory for the account) and, as appropriate, verify that identity. This is consistent with the Wolfsberg Principle 1.2.1, which states that the bank will establish the identity of its clients and beneficial owners prior to establishing business relationships with such persons1.
* D. The responsible private banker must obtain the necessary documentation establishing the authorized signer's authority to act on behalf of the account holder or beneficial owner (e.g. a Power of Attorney). This is consistent with the Wolfsberg Principle 1.2.3, which states that the bank will obtain the necessary documentation establishing the authority of the authorized signatory to act on behalf of the client or beneficial owner1.
* E. If an individual has signing authority over an account but does not act on a professional basis as a manager of funds, the responsible private banker must understand and document the relationship between that authorized signer, the account holder, and, if different, the beneficial owner of the account. This is consistent with the Wolfsberg Principle 1.2.4, which states that the bank will understand and document the relationship between the authorized signatory, the client and, if different, the beneficial owner of the account1.

According to the BSA/AML Manual1, one purpose of filing SARs is to identify violations or potential violations of law to the appropriate law enforcement authorities for criminal investigation. Therefore, when an institution receives a document request from law enforcement with regard to an STR that the institution has filed, it should cooperate and provide the documents that were previously collected to support the STR. This will help the law enforcement agency to conduct its investigation and follow up on the suspicious activity reported by the institution. The institution should also maintain the confidentiality of the STR and the document request, and avoid tipping off the customer or any other person involved in the suspicious activity.

Structuring transactions is a common method of money laundering, where cash deposits or withdrawals are broken down into smaller amounts to avoid reporting or record-keeping requirements. Employees who unintentionally assist customers in structuring transactions may not be aware of the legal and regulatory implications of their actions, or may have been misled or coerced by the customers. Therefore, the most appropriate and proportionate response is to provide remedial training to these employees, to ensure they understand the anti-money laundering policies and procedures, the red flags of suspicious activity, and their reporting obligations. Terminating, contacting law enforcement, or transferring these employees may be excessive, premature, or ineffective measures, depending on the circumstances and the level of involvement of the employees.

MSBs are frequently accused of being high risk for money laundering because they offer services that can facilitate the movement and conversion of illicit funds, such as currency exchange, money transmission, cheque cashing, and online payment. However, not all MSBs pose the same level of risk, and the degree of regulatory oversight and compliance requirements for MSBs may differ significantly depending on the jurisdiction they operate in. Some countries may have robust anti-money laundering (AML) regimes for MSBs, while others may have weak or inconsistent regulations, or even no regulations at all. This creates challenges and vulnerabilities for MSBs that operate across borders, as they may face different expectations and obligations from different authorities, or encounter gaps or loopholes in the AML framework. Moreover, some MSBs may operate informally or illegally, without registering or obtaining licenses from the relevant regulators, making them harder to detect and supervise. Therefore, MSBs are often perceived as high risk for money laundering, as they may be exploited by criminals who seek to take advantage of the regulatory discrepancies or deficiencies among countries.
