Navigating AML Risks in Correspondent Banking: Safeguarding the Global Financial System

Correspondent banking serves as the backbone of international finance, enabling seamless cross-border payments and fostering global commerce. By allowing banks to conduct transactions and provide services on behalf of other financial institutions—often across geographic and regulatory boundaries—correspondent banking makes much of international trade possible, especially for developing markets.

Yet, the complexity and broad reach of correspondent banking relationships introduce unique vulnerabilities. Chief among these are anti-money laundering (AML) risks, which demand ongoing vigilance from banks, regulators, and compliance professionals worldwide.

‍

Why Correspondent Banking Is Vital—And Vulnerable

Correspondent banking facilitates everything from trade settlements and international wire transfers to currency exchanges and cash management. Many regions, particularly those with less developed banking systems, rely heavily on these cross-border relationships to remain plugged into the global economy.

However, this intricate web of relationships lends itself to opacity, making it challenging to identify the true parties behind transactions and to detect illicit financial flows. Criminal organisations and bad actors exploit these weaknesses, leveraging correspondent networks to move and disguise illegal funds, sometimes with devastating consequences for the global financial system.

Key Money Laundering Risks in Correspondent Banking

1. Opacity and Complex Transaction Chains

Layered transaction chains—where funds pass through multiple account holders, intermediaries, and territories—make it incredibly difficult to trace the origins and ultimate beneficiaries of funds.

2. Inconsistent Regulatory Standards

Banks that operate across borders must navigate a patchwork of AML regulations, due diligence expectations, and reporting standards. Gaps between these regimes create opportunities for criminals to exploit the system and for illicit funds to slip through the cracks.

3. High Transaction Volumes

The sheer scale and speed of transactions processed in correspondent banking can obscure potentially suspicious activity, allowing illicit funds to blend more easily with legitimate flows.

4. Weak Due Diligence on Respondent Banks

If a correspondent bank’s respondent (the client institution) does not follow robust AML procedures, the entire chain can become compromised, introducing risk to every institution involved.

5. Misuse of Legal Structures

The use of shell companies, nominee accounts, and opaque ownership structures remain popular laundering techniques. These entities can serve as fronts to hide the true nature and control of funds.

How Criminals Exploit Correspondent Relationships

Criminals deploy a variety of schemes to take advantage of correspondent banking systems:

• Layering Transactions: Moving funds through multiple banks and jurisdictions to obscure their source.
• Structuring or “Smurfing”: Breaking transactions into smaller amounts to evade automated detection thresholds and reporting requirements.
• Regulatory Arbitrage: Exploiting weaker controls or oversight in certain countries to move money into the legitimate financial system.
• Identity Concealment: Using complex corporate structures or proxies to bypass KYC (Know Your Customer) requirements.

‍

The Unintended Risk of “De-Risking”

To minimise potential exposure, some banks have opted for de-risking—severing ties with entire regions, business types, or even countries that are considered high-risk. While this may seem like a prudent approach, it can actually undermine global financial integrity. By excluding whole regions from the formal banking sector, transactions shift to informal channels, making risks harder—not easier—to detect.

Global watchdogs, including the Financial Action Task Force (FATF), caution against blanket de-risking, warning that it can reduce transparency and impede legitimate economic activity.

Mitigating AML Risks in Correspondent Banking: Best Practices

Addressing the unique challenges of correspondent banking requires a proactive, collaborative approach. Among the recommended best practices:

1. Enhanced Due Diligence

• Banks should implement rigorous onboarding and ongoing monitoring for all correspondent and respondent bank relationships.
• Assessment should extend to the quality of the respondent’s AML framework, governance, and the jurisdictions they operate in.

2. Advanced Transaction Monitoring

• Implement real-time, risk-based transaction monitoring solutions capable of assessing high volumes and complex patterns.
• Machine learning and AI-driven solutions can help differentiate normal activity from potential red flags more accurately.

3. Accurate and Up-to-Date Reference Data

• Maintaining precise reference data on customers, counterparties, and jurisdictions is critical for AML compliance in correspondent banking. Inaccurate or outdated information can create significant blind spots, causing missed red flags and compliance breaches.
• Correct reference data ensures proper identification of counterparties, speeds up screening against watchlists, and minimises false positives during monitoring. This underpins all aspects of KYC, customer risk profiling, and transaction filtering—ultimately enabling financial institutions to prevent and detect illicit activity more effectively.
• Leveraging automated, always-current reference data solutions—such as those provided by BankCheck—empowers compliance teams to build resilience against evolving AML threats.

4. Improved Information Sharing

• International cooperation between financial institutions, regulators, and law enforcement enhances the real-time exchange of intelligence critical for detecting emerging risks.

5. Harmonisation with Global Standards

• Adherence to FATF recommendations and harmonisation with international norms not only reduces risk but also ensures continued access to the global financial system.

6. Ongoing Staff Training and Culture of Compliance

• Continuous education around new typologies, red flags, and regulatory requirements creates a culture where AML is seen as a shared responsibility.

The Way Forward: Collaboration, Technology, and Trusted Data

Correspondent banking will remain a lynchpin of the global economy for the foreseeable future. As technology advances and expectations tighten, financial institutions must invest not only in innovative compliance solutions, but also in the foundational element of reliable reference data. Only then can transaction monitoring, due diligence, and risk assessments reach their full effectiveness.

Reducing AML risk is no longer about merely checking the boxes—it’s about building resilience and trust in an ever-more interconnected world.
