What is Correspondent Bank?
A correspondent bank is a financial intermediary that provides services on behalf of another bank; especially when the two institutions do not have a direct relationship. Correspondent banks enable international banking transactions by bridging gaps in geographic coverage, currency access and operational capabilities. These banks help other banks conduct business in foreign jurisdictions where they lack a physical presence.
The concept of a CB evolved as global trade and finance expanded, making it impractical for every bank to maintain branches in every country. Instead, banks partner with CB to carry out essential functions such as foreign currency transfers, settlement and account maintenance.
Executive Summary
- A CB acts as an agent for another bank, particularly in international transactions.
- It supports transactions, currency exchange and settlement where direct relationships do not exist.
- Correspondent banks maintain accounts like Nostro, Vostro and Loro for handling foreign currencies.
- They are essential for cross border payments and global financial integration.
- Such banks must follow strict know your customer (KYC) and anti‑money laundering (AML) rules to prevent misuse.
How Correspondent Bank Works
Such banks facilitate international banking relationships by holding accounts and executing payments on behalf of other banks. When a bank needs to send money to or receive money from a region where it has no branch, it uses a correspondent relationship.
There are several types of accounts involved in this process:
- Nostro Accounts: Accounts that a home bank holds in a foreign currency with a CB.
- Vostro Accounts : Accounts that a CB holds on behalf of another bank, often in the correspondent’s local currency.
- Loro Accounts: Accounts referenced through a third bank’s relationship with another bank.
When bank A needs to pay bank B’s customer overseas, bank a routes the payment through its correspondent bank. The correspondent bank debits or credits the appropriate accounts, handles any required foreign exchange and forwards the funds; often using global messaging systems like SWIFT; to complete the transaction.
Such banks also offer services such as clearing checks drawn on foreign banks, processing international wires and enabling multicurrency account services, all while managing settlement and reconciliation.
