A correspondent bank is a financial institution that provides services on behalf of another bank, typically in a different country. It acts as an intermediary, enabling cross-border transactions between banks that have no direct relationship with each other, forming the backbone of international payment infrastructure.
As illustrated in a typical correspondent banking flow, a sending bank, which has no direct relationship with the recipient’s bank, routes a payment instruction through a correspondent bank that maintains accounts with both institutions. The correspondent bank debits the sending bank’s nostro account, transmits the payment message via SWIFT, and coordinates settlement with the receiving bank. This chain may involve one or more correspondent banks depending on the currencies and countries involved, with each correspondent bank holding the relevant account relationships needed to move funds along the payment route.

The Role of Correspondent Banks in Payment Processing #
Correspondent banks sit at the centre of international payment transactions. By maintaining accounts for other financial institutions – known as nostro and vostro accounts – they can send and receive payments on their clients’ behalf, ensuring capital moves efficiently across borders.
Clearing and Settlement
Correspondent banks manage the clearing and settlement of cross-border payment instructions. They use globally recognised systems such as SWIFT to securely transmit payment messages, ensuring funds are directed accurately and on time.
Currency Exchange
Correspondent banks provide currency exchange services, converting funds from one currency to another so that transactions can be settled in the recipient’s local currency. This removes the need for multiple separate currency conversions within a single payment chain.
Liquidity Management
Correspondent banks support liquidity by providing access to funds (typically in foreign currencies) and lines of credit. Through interbank lending and borrowing, they help financial institutions maintain stable operations, even during periods of market stress.
Compliance and Regulatory Oversight
Correspondent banks are responsible for regulatory compliance across the transactions they facilitate. This includes anti-money laundering (AML) controls, know-your-customer (KYC) requirements, and know-your-transaction (KYT) controls, reducing the risk of financial crime in cross-border banking.
FAQ: #
What are nostro and vostro accounts?
- Nostro and vostro are two terms that describe the same correspondent banking account from different perspectives. The term comes from the Latin for “ours”, and nostro account is an account that a bank holds at a foreign correspondent bank, denominated in the foreign currency. A vostro account is the same account viewed from the correspondent bank’s perspective – the term comes from the Latin for “yours”. These accounts are the operational foundation of correspondent banking, holding the pre-funded balances that enable cross-border payments to be settled.
How is a correspondent bank different from an intermediary bank?
- While the terms are often used interchangeably, a correspondent bank has a formal, pre-established banking relationship with the institutions it serves, whereas an intermediary bank may be used on a one-off basis to route a specific transaction. Correspondent banks also typically hold accounts on behalf of their partner institutions.
