Correspondent banking is a service that allows banks to access financial services in different jurisdictions through intermediary banks, known as correspondent banks. Correspondent banking can facilitate cross-border transactions, foreign exchange, and other financial activities for banks and their customers. However, correspondent banking also poses various risks, such as money laundering, terrorist financing, fraud, corruption, tax evasion, and sanctions evasion. Correspondent banks may have no direct relationship with the customers of the respondent banks, making it difficult to verify their identity and monitor their transactions.
Correspondent banks may also rely on the compliance programs of the respondent banks, which may not meet the standards of the correspondent banks' jurisdictions.
One of the risk factors that increases the risk for a correspondent bank is being a major service provider to money service businesses (MSBs). MSBs are entities that provide money transmission, currency exchange, check cashing, prepaid cards, and other similar services. MSBs are often considered high-risk customers, because they may serve as conduits for illicit funds, especially if they operate in jurisdictions with weak anti-money laundering regulations or oversight. MSBs may also have a large and diverse customer base, making it challenging to conduct customer due diligence and transaction monitoring. Therefore, correspondent banks that provide services to MSBs may face higher exposure to money laundering and other financial crimes, and may need to apply enhanced due diligence and risk mitigation measures.

A comprehensive risk analysis is the first and most important step in developing an effective anti-money laundering program. A risk analysis helps a financial institution identify and assess its exposure to money laundering and terrorist financing risks, based on its products, services, customers, geographic locations, and other factors. A risk analysis also enables a financial institution to tailor its policies, procedures, controls, and training to mitigate the specific risks it faces. A risk analysis should be conducted periodically and updated as necessary to reflect changes in the institution's risk profile.
