An intermediary bank is a financial institution that sits between your bank and the recipient's bank when a wire transfer crosses international borders or moves through the banking system in a way that requires routing through multiple institutions.

When you send money internationally, your bank may not have a direct relationship with the recipient's bank. Instead of sending the funds directly, your bank routes the transfer through one or more intermediary banks that do have relationships with both sides. The intermediary bank receives the funds, verifies the details, and passes the money along to the next bank in the chain until it reaches the recipient's bank.

This happens automatically — you don't choose which intermediary banks are used, and you typically don't know their names unless something goes wrong. The routing depends on the banking networks available, the countries involved, and the correspondent banking relationships your bank has established.

Key Takeaways

  • Intermediary banks are used when your bank and the recipient's bank don't have a direct relationship, which is common in international transfers.
  • Each intermediary bank in the chain may deduct a fee from the transfer amount, which can reduce what the recipient actually receives.
  • The more intermediary banks involved, the longer the transfer takes and the higher the total cost.
  • You can ask your bank which intermediary banks will be used before you send the transfer, though they may not know until the transfer is processed.
  • Some banks and money transfer services use fewer intermediaries or none at all, which can save money and time on international transfers.

Why intermediary banks are necessary

Banks don't maintain direct relationships with every other bank in the world. Instead, they establish correspondent banking relationships with a smaller network of banks in key financial centers. When you send money to a country or bank outside that network, the transfer has to pass through one of those correspondent banks first.

Think of it like the postal system: your local post office doesn't have a direct route to every address in the world, so mail gets sorted through regional hubs before reaching its final destination. Intermediary banks work the same way — they're the sorting hubs of the banking system.

The number of intermediaries depends on the destination country, the currency involved, and whether the recipient's bank has its own direct relationship with your bank. A transfer to a major financial center like London or Singapore might use one intermediary. A transfer to a smaller country or a rural area might use two or three.

How intermediary bank fees reduce what the recipient gets

Each intermediary bank in the chain can deduct a fee for handling the transfer. These are called intermediary bank fees or correspondent bank fees, and they're separate from the fee your own bank charges you.

Here's how it works in practice: you send $1,000 from your U.S. bank to someone in India. Your bank charges you $15. The transfer goes to an intermediary bank in London, which deducts $10. Then it goes to another intermediary bank in the Middle East, which deducts $8. By the time the money reaches the recipient's bank in India, only $967 is left. The recipient receives $967, not $1,000, and you've paid $33 in total fees across the system.

The recipient usually doesn't know how much was deducted until the money arrives in their account. You can ask your bank to tell you the intermediary fees before you send, but many banks can't provide this information until after the transfer is processed, because the routing isn't final until the transfer enters the system.

How to find out which intermediary banks will be used

Before you send an international wire transfer, call your bank and ask them to provide the SWIFT code or routing information for the recipient's bank. Then ask your bank which intermediary banks will be used and what fees each one will charge.

Your bank may not be able to answer this question completely. Some banks don't know the full routing path until the transfer is actually sent. In that case, ask your bank for the intermediary bank fees that are typical for that destination country, or ask whether they can send the transfer with fewer intermediaries.

You can also ask the recipient's bank directly. Give them your bank's name and SWIFT code, and ask them what intermediary banks are typically used for transfers from your country. This gives you a sense of what to expect, though the actual routing may vary.

Transfers with no intermediary banks

Some transfers don't require intermediary banks at all. If your bank has a direct correspondent relationship with the recipient's bank, the money can move directly from one to the other. This is more common when both banks are large institutions in major financial centers, or when they're part of the same international banking network.

You can ask your bank whether a direct transfer is possible for your specific recipient. If it is, the transfer will be faster and may have lower fees, since there are no intermediary bank fees to pay.

Some money transfer services and fintech companies also avoid intermediary banks by using different infrastructure — for example, by holding accounts in multiple countries and moving money between their own accounts rather than routing through the traditional banking system. These services often advertise lower fees and faster delivery times, though they may have limits on how much you can transfer or which countries they serve.

How intermediary banks affect transfer speed

Each intermediary bank in the chain adds time to the transfer. Your bank sends the money to the first intermediary, which verifies it and sends it to the next intermediary, which does the same, and so on. Each step typically takes one business day.

A direct transfer might arrive in one to two business days. A transfer with two intermediary banks might take three to five business days. A transfer with three or more intermediaries can take a week or longer, especially if one of the intermediary banks is in a time zone far from the others or if there are delays in the verification process.

International wire transfers are not instantaneous, even though the money moves electronically. The delays are built into the system because each bank has to verify the transfer details and ensure the money is legitimate before passing it along.

What information intermediary banks need

When you send a wire transfer, you provide your bank with the recipient's name, account number, bank name, and SWIFT code. Your bank passes this information to the first intermediary bank, which passes it to the next, and so on down the chain.

Each intermediary bank verifies that the information is correct and that the account exists before passing the money along. If there's an error in the account number or the recipient's name, the transfer can be rejected or delayed while the banks try to figure out where the money should go.

This is why it's critical to get the recipient's banking details exactly right before you send. Ask the recipient to provide their account number and SWIFT code in writing, and double-check both before you initiate the transfer. A small typo can cause the transfer to fail or be sent to the wrong account.

Frequently Asked Questions

Can I choose which intermediary banks are used?

No. Your bank chooses the routing based on its correspondent banking relationships and the destination country. You can ask your bank to use fewer intermediaries or to route through specific banks if you have a preference, but your bank may not be able to accommodate that request.

Will the recipient know how much was deducted in intermediary fees?

The recipient will see the amount that arrived in their account, but they may not know how much was deducted in fees along the way. If you want to know the exact amount they'll receive, ask your bank to estimate the intermediary fees before you send, or ask the recipient to tell you what amount arrived after the transfer is complete.

What happens if an intermediary bank rejects the transfer?

If an intermediary bank finds an error in the transfer details or suspects fraud, it can reject the transfer and send the money back to your bank. Your bank will then return the funds to your account, usually within a few business days. You'll need to correct the error and send the transfer again.

Are intermediary bank fees the same every time?

No. Fees vary depending on the destination country, the banks involved, the amount being transferred, and the currency. The same transfer sent on different days might use different intermediary banks and incur different fees.

Is there a way to avoid intermediary banks entirely?

For some destinations and some banks, yes — a direct transfer is possible. For others, intermediary banks are unavoidable because the banking infrastructure requires it. Money transfer services and some fintech companies may offer alternatives that avoid traditional intermediary banks, though they may have different fees or limits.
