An intermediary bank is a financial institution that sits between your bank and the recipient's bank when money moves internationally.

When you send money to another country, your bank often cannot reach the recipient's bank directly. Instead, your bank sends the payment to an intermediary bank—sometimes called a correspondent bank—which then forwards it to the final destination. The intermediary bank acts as a middleman, translating payment instructions, converting currency if needed, and ensuring the money reaches the right account in the right country.

This happens most often with wire transfers and international ACH payments. You may never see the intermediary bank's name, but it takes a cut of the money and adds time to the transfer. Understanding how intermediary banks work helps explain why international payments cost more and take longer than domestic ones.

Key Takeaways

  • An intermediary bank receives your payment from your bank and passes it to the recipient's bank, acting as a required link in the chain when banks cannot connect directly.
  • Multiple intermediary banks may handle a single transfer, especially for payments to remote countries or smaller banks, adding both cost and delay.
  • Each intermediary bank deducts a fee from the transfer amount, which is why the recipient may receive less than you sent.
  • The SWIFT network and routing codes determine which intermediary banks are used, and you typically cannot choose them yourself.
  • International transfers routed through intermediary banks usually take three to five business days, compared to one day for domestic wire transfers.

How the intermediary bank fits into the payment chain

When you initiate an international wire transfer, your bank looks up the recipient's bank using a SWIFT code (a standardized identifier for banks worldwide). If your bank has a direct relationship with that bank, the money goes straight there. If not, your bank sends the payment to an intermediary bank that does have a relationship with the recipient's bank.

The intermediary bank receives the payment in its own account, verifies the details, and then sends it forward. This can happen in a chain: your bank → intermediary bank A → intermediary bank B → recipient's bank. Each step adds a processing fee and typically one business day to the timeline. The longer the chain, the more expensive and slower the transfer becomes.

Your bank tells you the recipient will receive the money, but it does not always tell you how many intermediary banks will handle it or how much each will deduct. This is why you may send $1,000 and the recipient gets $950—the $50 went to intermediary bank fees.

Why intermediary banks exist and what they charge

Banks do not have direct relationships with every other bank in the world. An intermediary bank solves this by maintaining accounts at multiple banks across different countries and currencies. When your bank needs to reach a bank it does not know, it uses the intermediary bank's existing relationship instead of building one itself.

Intermediary banks charge for this service. The fee is usually deducted from the amount being transferred, so the recipient gets less than you sent. Fees vary widely—some intermediary banks charge $10 to $25 per transfer, while others charge a percentage of the amount. Your bank may also charge a separate fee for using an intermediary bank, on top of what the intermediary bank itself takes.

Smaller banks and banks in developing countries rely heavily on intermediary banks because they lack the infrastructure to connect directly to major international networks. This is why a transfer to a small rural bank in a remote country may pass through three or four intermediaries, while a transfer to a major bank in London may go through only one.

The role of SWIFT codes and routing information

When you send an international payment, you provide the recipient's SWIFT code (also called a BIC code) and their account number. The SWIFT code identifies the recipient's bank and tells your bank which intermediary banks to use. SWIFT is a messaging system that connects banks worldwide and routes payment instructions through the intermediary network.

Your bank uses the SWIFT code to determine the fastest and cheapest path to the recipient's bank. Sometimes your bank chooses the path; sometimes the intermediary bank chooses the next step. You have no control over which intermediary banks are used, and you cannot request a specific route.

If you provide an incorrect SWIFT code, the payment may be sent to the wrong bank or rejected entirely. If it reaches the wrong bank, recovery can take weeks because the intermediary banks must trace the payment backward through the chain.

How long intermediary banks add to your transfer

A domestic wire transfer typically clears in one business day. An international transfer routed through one intermediary bank usually takes two to three business days. Each additional intermediary bank adds roughly one more business day.

The timeline depends on several factors: the number of intermediary banks involved, the time zones they operate in, whether weekends or holidays fall during the transfer, and whether any bank flags the payment for compliance review. A transfer sent on a Friday afternoon may not begin processing until Monday, and if an intermediary bank is in a different time zone, additional delays are common.

Some banks offer expedited international transfers that bypass certain intermediary banks or use alternative networks like CHIPS (for US dollar transfers) or local clearing systems. These are faster but more expensive. Standard international transfers are the default because they are cheaper, even though they take longer.

What happens if an intermediary bank holds or rejects your payment

An intermediary bank can reject a payment if the information does not match its compliance rules. Banks are required to screen payments for fraud, money laundering, and sanctions violations. If an intermediary bank suspects a problem, it may hold the payment for review, which adds days or weeks to the timeline.

Common reasons for holds include: the recipient's name does not match the account exactly, the amount seems unusually large for that account, the sender is from a high-risk country, or the payment purpose is unclear. The intermediary bank may contact your bank for clarification, and your bank may contact you. During this time, your money is frozen in the intermediary bank's account.

If an intermediary bank rejects the payment outright, it is sent back to your bank, which then returns it to your account. This reversal can take another week. You are not charged a fee for a rejected payment in most cases, but you lose time and may incur a fee from your own bank for initiating the transfer.

Alternatives to using intermediary banks

If you send money internationally often, you have options beyond traditional wire transfers. International ACH transfers use the automated clearing house system and are cheaper than wire transfers, though they take longer (five to ten business days) and may still use intermediary banks. Money transfer services like Western Union or MoneyGram use their own networks and may avoid some intermediary banks, but they charge higher fees and offer worse exchange rates than banks.

Peer-to-peer transfer apps like Wise (formerly TransferWise) and OFX use local bank accounts in multiple countries to avoid intermediary banks entirely. Instead of sending money across borders, you send it to a local account in your country, and the app sends local money to the recipient from an account in their country. This is faster and cheaper, but only works for countries where the app operates.

For very large transfers, some banks offer direct correspondent banking relationships, which means your bank sends the money straight to the recipient's bank without an intermediary. This requires your bank to have an account at the recipient's bank, which is more common between major international banks than between small regional banks.

Frequently Asked Questions

Can I see which intermediary banks handled my transfer?

Your bank may provide this information if you ask, but it is not always available. Some banks show the intermediary bank names in the transaction details; others do not. If you need to trace a payment that was delayed or lost, your bank can request this information from the intermediary banks, though it may take several days.

Why did the recipient get less money than I sent?

Intermediary bank fees are deducted from the transfer amount before the money reaches the recipient. Your bank may also charge a separate fee. Ask your bank upfront how much the recipient will receive after all fees, rather than finding out after the transfer is complete.

Can I choose a different intermediary bank to save money?

No. Your bank selects the intermediary banks based on its relationships and the recipient's bank location. You cannot request a specific intermediary bank or route. Some banks offer cheaper international transfer options (like international ACH or money transfer services), so comparing options before you send is your best way to control costs.

What should I do if my transfer is stuck at an intermediary bank?

Contact your bank immediately and provide the wire reference number. Your bank can contact the intermediary bank to find out why the payment is held and what information is needed to release it. This process usually takes three to five business days. Do not send the money again—wait for your bank to resolve the hold first.

Do intermediary banks apply their own exchange rates?

Yes. If your transfer involves currency conversion, each intermediary bank may apply its own exchange rate and markup. This is separate from the fee they charge. The total cost of an international transfer includes the intermediary bank fee, your bank's fee, and the exchange rate markup—which is why comparing total cost matters more than comparing individual fees.
