Correspondent banking remains a critical backbone of cross-border payments, trade finance, and financial inclusion, yet it is also a persistent exposure point for money laundering and terrorist financing (AML/CTF) risk. These risks intensify in nested correspondent relationships where respondent banks provide downstream access to their own clients or other financial institutions because transparency diminishes across the payment chain and accountability for controls can become fragmented. This study examines how financial institutions can manage AML/CTF risk in correspondent and nested relationships while meeting evolving expectations for risk-based due diligence, transaction monitoring, and ongoing oversight across multiple jurisdictions. The research synthesizes regulatory guidance, supervisory enforcement themes, and industry practices to develop a structured framework for (i) risk scoping and customer/relationship classification, (ii) enhanced due diligence (EDD) for nested access, including governance, ownership, sanctions exposure, and AML program effectiveness, and (iii) monitoring and escalation standards that integrate payment-message data quality, typology-driven alerts, and periodic relationship reviews. Methodologically, the study employs comparative policy analysis across key regulatory regimes and a scenario-based assessment using representative nested-relationship typologies (e.g., indirect access to high-risk geographies, fintech/payment intermediary layering, and payable-through account–like structures) to identify practical control gaps and feasible mitigations. The expected contribution is a set of actionable, risk-proportionate recommendations and monitoring expectations that balance financial crime compliance with the operational realities of cross-border banking, supporting safer access to the global financial system without unnecessary de-risking.
