# Correspondent Bank: Definition and How It Works

## What Is a Correspondent Bank?

A correspondent bank serves as an intermediary financial institution, enabling domestic banks to execute cross-border transactions and access foreign financial markets without the need to establish physical branches abroad. These banks are essential for facilitating wire transfers, conducting business transactions, [accepting deposits](https://www.investopedia.com/terms/i/interbank-deposits.asp), and processing documentation on behalf of their partner banks, often in different countries. By acting as agents, correspondent banks expand the capabilities of domestic banks, allowing them to efficiently serve international clients and operate in global markets.

### Key Takeaways

*   Correspondent banks act as intermediaries that enable domestic banks to execute international transactions without establishing foreign branches.
*   These banks facilitate wire transfers, accept deposits, and handle currency exchanges, allowing domestic banks to access foreign markets.
*   Correspondent banks engage in managing nostro and vostro accounts to keep track of international transactions and fees.
*   The reliance on third-party banks for Know Your Client (KYC) compliance makes correspondent banking high-risk for money laundering.
*   Distinct from intermediary banks, correspondent banks often handle transactions in multiple currencies, while intermediary banks typically process transactions in a single currency.

## Understanding the Role of Correspondent Banks in International Banking

Correspondent banks are third-party banks. They serve as intermediaries for different banks. As such, they provide treasury services between sending and receiving banks, especially those in different countries. Services can include:

*   funds transfer
*   settlement
*   check clearing
*   wire transfers
*   currency exchange

Correspondent banks can also handle local [transactions](https://www.investopedia.com/terms/t/transaction.asp) for clients traveling abroad. Locally, correspondent banks can accept [deposits](https://www.investopedia.com/terms/b/bank-deposits.asp), handle documentation, and manage fund transfers.

The accounts shared between correspondent banks and their client banks are called [nostro and vostro accounts](https://www.investopedia.com/ask/answers/051815/what-difference-between-nostro-and-vostro-account.asp). A bank's account for another is a nostro account, meaning "our account on your books." The same account is referred to as a vostro account—your account but on our books—by the [counterparty](https://www.investopedia.com/terms/c/counterparty.asp) bank. Typically, both banks in a correspondent relationship maintain accounts with each other to track debits and credits.

Correspondent banks are essential for domestic banks that can't open [branches](https://www.investopedia.com/terms/b/branch-banking.asp) in other countries.

A small domestic bank with international clients can partner with a correspondent bank to serve these needs. Doing so also gives it access to the foreign financial market. The correspondent bank will, therefore, charge a [fee](https://www.investopedia.com/terms/f/fee.asp) for this service, which is usually passed off from the domestic bank to the customer.

## Important Factors to Consider in Correspondent Banking

International wire transfers often occur between banks that don't have an established financial relationship. For example, a bank in San Francisco that receives instructions to wire funds to a bank in Japan can't wire funds directly without a working relationship with the receiving bank.

Most international wire transfers go through the [Society for Worldwide Interbank Financial Telecommunication (SWIFT)](https://www.investopedia.com/terms/s/swift.asp) network. Knowing there isn't a working relationship with the destination bank, the originating bank can search the SWIFT network for a correspondent bank that has arrangements with both banks.

Once it finds a suitable correspondent bank, the sending bank transfers funds to its nostro account there.

Using the example above, the correspondent bank deducts its transfer fee, usually between $0 and $50, and transfers the funds to the receiving bank in Japan. The correspondent bank adds [value](https://www.investopedia.com/terms/v/value.asp) by offering two key benefits:

*   It alleviates the need for the domestic bank to establish a physical presence abroad.
*   It saves the work of setting up direct arrangements with other [financial institutions](https://www.investopedia.com/terms/f/financialinstitution.asp) around the world.

### Potential Risks and Challenges in Correspondent Banking

Correspondent banking has risk challenges since it depends on the respondent bank for [Know Your Client (KYC)](https://www.investopedia.com/terms/k/knowyourclient.asp) checks.

Reliance on a third party’s compliance program—rather than conducting KYC on all customers for whom the respondent bank is processing payments through the correspondent bank—is why this activity is generally considered to be high-risk, from a [money-laundering](https://www.investopedia.com/terms/m/moneylaundering.asp) perspective.

## Comparing Correspondent Banks and Intermediary Banks

Although there are some similarities between both [correspondent and intermediary banks](https://www.investopedia.com/ask/answers/062515/what-difference-between-correspondent-bank-and-intermediary-bank.asp)—namely that they act as third parties for other banks—there is a major difference between the two.

While correspondent banks normally handle transactions involving multiple [currencies](https://www.investopedia.com/terms/c/currency.asp), an intermediary bank completes transactions involving only a single currency. They are especially key for domestic banks that may be too small in size to handle these types of transactions.

## What Is a Correspondent Bank?

A correspondent bank is a third-party financial institution that acts as a go-between for domestic and foreign banks that need to conduct cross-border payments with each other.

## What Is the Difference Between a Correspondent Bank and an Intermediary Bank?

Correspondent banks and intermediary banks both serve as third-party banks and are used by beneficiary banks, or receiving banks, to execute international fund transfers and transaction settlements. The main variance between correspondent banks and intermediary banks is often the number of currencies in use in a transaction, with correspondent banks handling more than one currency and intermediary banks generally working in one currency.

## How Does a Correspondent Bank Add Value?

In transactions that require their use, the correspondent bank adds value in two ways. It alleviates the need for the domestic bank to establish a physical presence abroad and saves the work of setting up direct arrangements with other financial institutions around the world.

## The Bottom Line

A correspondent bank is an authorized financial institution that provides third-party services on behalf of another financial institution that's usually in another country. Correspondent bank services may include funds transfer, settlement, check clearing, wire transfers, and more. Domestic banks can serve their international clients and gain access to foreign financial markets by using correspondent banks, rather than setting up their own branches overseas.
