The foundations

Understanding Correspondent Banking

Correspondent banking generally involves an arrangement in which one financial institution provides banking services to another institution. The relationship can allow a bank to access services in a jurisdiction or currency where it does not have a direct operational presence.

For example, a bank may maintain an account with another bank to facilitate payments in a foreign currency. The correspondent institution may process transactions, hold balances or provide other agreed services to the respondent institution, subject to the arrangement and applicable rules.

Correspondent banking relationships differ in scope, structure and complexity. The services available depend on the institutions involved, their agreements, the currencies and jurisdictions concerned, and relevant legal and regulatory requirements.

How it works

How Correspondent Banking Relationships Operate

Correspondent banking enables institutions to work through established banking connections rather than independently maintaining a physical presence and direct access to every payment system in every market.

In a typical arrangement, a respondent bank may hold an account with a correspondent bank. The account and associated services can be used to support eligible payments or other agreed banking activities. The precise process depends on the payment route, currencies, institutions and settlement arrangements involved.

Correspondent and respondent institutions

The correspondent bank provides agreed services to another financial institution. The respondent bank uses those services to support its own activities and, where permitted, the needs of its customers. Each institution retains responsibilities arising from its role, contractual arrangements and applicable regulations.

Accounts and payment instructions

Accounts maintained between institutions can facilitate the movement and settlement of funds. Payment instructions may pass through multiple institutions before reaching the beneficiary's bank. Each stage can involve screening, processing requirements, fees, settlement considerations and checks on the information accompanying the transaction.

Currency and jurisdiction considerations

International banking arrangements may involve different currencies, legal systems, operating hours and regulatory frameworks. These differences can affect processing times, documentation requirements, transaction costs and the handling of exceptions.

Institutions should understand the relevant payment chain and establish clear operational procedures for tracing payments, investigating delays and resolving discrepancies.

International payments

Supporting Cross-Border Financial Activity

Correspondent banking can help connect institutions to international payment networks and foreign-currency banking services. These connections may support a range of activities, including trade-related payments, remittances and other permitted transfers between jurisdictions.

For businesses operating internationally, reliable payment arrangements can be an important part of managing suppliers, customers and financial obligations across borders. For financial institutions, correspondent relationships can provide access to services that would otherwise require additional infrastructure or direct market relationships.

However, the availability, speed and cost of a payment depend on the specific route, currencies, participating institutions, compliance checks and settlement systems. Not every institution has access to every currency or service, and transactions may be delayed or declined when additional information or regulatory review is required.

Trade and commercial payments

International trade often requires payments between buyers and sellers in different countries. Banking connections can help institutions process relevant transfers and manage settlement through the appropriate channels. Payment services should be considered alongside the underlying commercial documentation and the parties' responsibilities.

Access to foreign currencies

Correspondent relationships may support payments in currencies for which an institution does not operate its own local banking infrastructure. Currency availability, exchange arrangements, liquidity, fees and cut-off times should be understood before committing to a payment timetable.

Operational continuity

Institutions should consider the resilience of their payment arrangements, including the effect of service interruptions, changes in correspondent relationships and disruptions in a particular market. Contingency planning can help identify alternative arrangements where they are available and appropriate.

Compliance and due diligence

Know Your Counterparty and Understand the Risks

Correspondent banking requires careful assessment because institutions may process payments for customers and activities beyond their direct relationship. The nature of the relationship can create risks involving financial crime, sanctions, legal compliance, operational failures and reputational damage.

Financial institutions should apply risk-based due diligence appropriate to the relationship, services and applicable regulatory framework. The specific requirements depend on the jurisdictions involved and the relevant laws and supervisory expectations.

Know Your Customer and counterparty assessment

Institutions may need to understand a prospective correspondent's ownership, management, business activities, customer base, regulatory status, financial crime controls and the purposes for which the relationship will be used.

Due diligence should be proportionate to the risks identified and completed before establishing a relationship. Relevant information should be verified where required and refreshed as circumstances change.

Anti-money laundering and counter-terrorist financing

Correspondent banking controls commonly include measures designed to identify and manage money laundering and terrorist financing risks. Institutions should understand the nature of the payment activity they support and ensure that appropriate policies, screening, monitoring and escalation arrangements are in place.

Responsibilities should be clearly documented. A correspondent relationship does not automatically transfer one institution's legal obligations to another or remove the need for each institution to meet the requirements applicable to its own activities.

Sanctions and restricted activity

Sanctions requirements vary by jurisdiction and can apply to parties, countries, sectors or specific transactions. Institutions should identify which legal regimes apply to their activities and maintain suitable controls to detect and handle potentially prohibited transactions.

Transparency and information quality

Accurate information about the parties, purpose and payment details is important to effective screening and monitoring. Missing, inconsistent or incomplete information can lead to delays, requests for clarification, rejection of payments or additional scrutiny.

Risk management

Managing Financial, Operational and Reputational Risks

Correspondent banking involves several categories of risk. A sound framework should identify these risks, assess their potential impact and establish appropriate controls throughout the relationship.

• Counterparty risk: the possibility that a financial institution will fail to meet its obligations under an arrangement.
• Financial crime risk: exposure to transactions associated with money laundering, terrorist financing, sanctions breaches or other prohibited activity.
• Operational risk: failures in systems, processing, information exchange, staffing or transaction reconciliation.
• Legal and regulatory risk: the consequences of failing to meet applicable laws, regulatory requirements or contractual obligations.
• Liquidity and settlement risk: the possibility that funds will not be available at the expected time or that settlement will not occur as planned.
• Reputational risk: damage arising from involvement in problematic activity, control failures or a breakdown in trust between institutions.

Risk assessments should be reviewed periodically and when material changes occur. These may include changes in ownership, geographic exposure, products, transaction volumes, regulatory status or the quality of information available.

Institutions should also establish clear procedures for escalating concerns, investigating unusual activity, documenting decisions and managing the suspension or termination of relationships where necessary.

Technology and controls

Improving Transparency and Operational Efficiency

Technology can support correspondent banking through more consistent payment information, transaction screening, reconciliation and monitoring. Digital tools may help institutions identify exceptions and improve visibility across payment processes, provided they are implemented with suitable controls.

Automation does not remove the need for human oversight. Systems require reliable data, appropriate access permissions, testing, maintenance and procedures for handling errors or unusual activity. Institutions should also understand the limitations of screening and monitoring tools.

Payment information and traceability

Consistent data can help participating institutions identify parties, investigate delays and respond to requests for information. Clear procedures for sharing relevant information can support operational coordination while respecting applicable privacy, confidentiality and data-protection requirements.

Cybersecurity and business continuity

Cross-border payment processes rely on secure systems and dependable communications. Institutions should consider cyber threats, access controls, third-party dependencies, incident response and continuity planning as part of their operational risk framework.

Monitoring performance

Operational reporting can track processing times, rejected or delayed payments, reconciliation exceptions, investigation volumes and other relevant indicators. Reviewing these measures may help identify recurring issues and areas where controls or processes need improvement.

Relationship management

Building Sustainable Institutional Relationships

Establishing and maintaining a correspondent banking relationship requires more than agreeing commercial terms. Institutions need to understand the proposed activities, responsibilities, risk profile, operational requirements and ongoing information obligations.

A disciplined relationship-management process may include:

• Defining the business purpose and expected scope of the relationship.
• Completing appropriate due diligence before services begin.
• Agreeing contractual responsibilities, service parameters and escalation routes.
• Establishing secure communication and payment-investigation procedures.
• Monitoring activity and reviewing the relationship periodically.
• Maintaining clear records and addressing control weaknesses promptly.

Relationships should remain consistent with each institution's risk appetite, operational capabilities and legal obligations. Commercial objectives should not override compliance requirements or appropriate risk controls.

The outlook

Connecting Financial Institutions Responsibly

Correspondent banking remains an important mechanism for connecting financial institutions across currencies and jurisdictions. It can support international payments and wider financial activity where institutions have suitable arrangements and meet the relevant requirements.

Its effectiveness depends on sound due diligence, clear responsibilities, reliable payment processes, accurate information and ongoing oversight. Institutions must also remain alert to changes in financial crime risks, regulation, technology and the availability of correspondent services.

A responsible approach balances the benefits of international connectivity with a clear understanding of the risks. Strong institutional relationships are built through transparency, appropriate controls and consistent compliance rather than access alone.
