What intermediary banking is and why it exists

Intermediary banking is when one bank sends your money through one or more other banks before it reaches the final destination. The sending bank does not have a direct connection to the receiving bank, so it uses an intermediary — a bank that has relationships with both sides — to move the funds along.

This happens most often in international transfers, but also in domestic payments between smaller banks or regional institutions. The intermediary bank receives the money from the sending bank, verifies it, and passes it to the next bank in the chain. Each step takes time and may involve a fee.

Think of it like mail: if you want to send a letter to someone in another country, you might give it to your local post office, which sends it to a regional hub, which sends it to an international sorting facility, which sends it to the destination country's postal service, which finally delivers it to the recipient. Each stop is an intermediary.

Key Takeaways

  • Intermediary banks exist because not all banks have direct relationships with each other, especially across borders or between smaller institutions.
  • Each intermediary bank in the chain takes a fee, usually between $10 and $50 per transfer, and adds processing time.
  • International transfers almost always use at least one intermediary bank; domestic transfers usually do not unless the banks are small or regional.
  • You can sometimes see which intermediary banks will be used before you send the money by asking your bank for the routing path or SWIFT details.
  • Correspondent banking relationships — formal agreements between banks — determine whether a transfer can happen at all and how long it takes.

How the chain of banks actually moves your money

When you send money internationally, your bank does not usually contact the receiving bank directly. Instead, your bank sends the payment to an intermediary bank that it has a relationship with. That intermediary bank then sends it to another intermediary, or directly to the receiving bank if one of them has a relationship with it.

Each bank in the chain uses a SWIFT code — a standardized identifier that tells the system which bank is which and where to send the money next. The sending bank includes the SWIFT code of the intermediary in the payment instructions. The intermediary receives the funds, checks that the amount and account details match, and forwards it along with a new set of instructions to the next bank.

The entire chain can be two banks (sending bank and receiving bank) or five or more, depending on whether direct relationships exist. A transfer from a small regional bank in the United States to a small regional bank in India might pass through a large money center bank in New York, then a large bank in London, then a bank in the Middle East, then finally to the receiving bank — each one an intermediary.

Why intermediary banks charge fees and add time

Each intermediary bank charges a fee for handling the transfer. These fees are called intermediary fees or correspondent bank fees, and they are separate from the fee your own bank charges you. A single international transfer might have two or three intermediary fees stacked on top of each other, each one reducing the amount that arrives at the destination.

The fees exist because each bank has to verify the payment, check it against sanctions lists and anti-money-laundering rules, update its own ledgers, and send it onward. Smaller banks especially rely on these fees because they do not have the infrastructure to process international payments on their own.

Time adds up the same way. If each intermediary bank takes one business day to process and forward the payment, a three-bank chain takes three days. Add weekends and holidays, and a transfer that should take two days can take five or six. The receiving bank may also hold the funds for an extra day while it verifies the source.

Correspondent banking relationships and why some transfers fail

Banks do not automatically work with every other bank. Instead, they form correspondent banking relationships — formal agreements that allow them to send and receive payments on each other's behalf. These relationships require both banks to meet certain standards: they must have compatible systems, comply with the same regulations, and trust each other to handle money correctly.

If your bank does not have a correspondent relationship with the receiving bank, and no intermediary bank has relationships with both, the transfer cannot happen at all. This is rare in developed countries but common when sending money to smaller banks in developing countries, or to banks in countries under sanctions.

Some banks have ended correspondent relationships in recent years because of the cost of compliance — especially anti-money-laundering checks. This has made it harder to send money to certain regions, even for legitimate purposes. If a transfer fails, your bank will tell you that no routing path exists and return your money.

The difference between intermediary banking and direct banking

Direct banking happens when your bank has its own relationship with the receiving bank and can send the money without using an intermediary. This is faster and cheaper because there are no extra fees and no extra processing steps. Most domestic transfers in the United States use direct banking — your bank sends the money straight to the receiving bank using the Federal Reserve's systems.

International transfers between large banks often use direct banking too. If you send money from Bank of America to HSBC, both banks have offices and relationships worldwide, so the money can move directly. But if you send money from a small credit union to a bank in another country, intermediaries are almost certain to be involved.

You can ask your bank whether a specific transfer will use intermediaries. Some banks will tell you the routing path before you send the money. Others will only tell you after the fact, when the transfer has already been processed and the fees have been deducted.

How to reduce intermediary fees and delays

The most direct way to avoid intermediary fees is to use a bank that has a direct relationship with the receiving bank. Large international banks like HSBC, Citibank, and Deutsche Bank have offices in many countries and can often send money directly. If you are sending money regularly to the same country or bank, it is worth asking your bank whether a direct route exists.

Some payment services — including some fintech companies and money transfer specialists — use different routing paths than traditional banks. They may have relationships with banks in the destination country that your bank does not, allowing them to avoid intermediaries or use cheaper ones. These services usually charge a flat fee or a percentage, which may be lower than the combined cost of your bank's fee plus multiple intermediary fees.

You can also reduce delays by sending the payment early in the week and early in the day. Banks process payments in batches, and a payment sent on Friday afternoon may not move until Monday. Weekends and holidays add extra days to the timeline.

Intermediary banking in domestic transfers

Domestic transfers in the United States rarely use intermediaries because the Federal Reserve operates a centralized system that all banks can access. When you send money from one U.S. bank to another, the Federal Reserve handles the routing and settlement, and no intermediary bank is needed.

However, some domestic transfers do use intermediaries. If you send money to a very small bank or credit union that does not have a Federal Reserve account, the receiving bank's own bank (called a sponsor bank) may act as an intermediary. The funds go to the sponsor bank first, then to the small institution. This is invisible to you — the money still arrives in the account you specified — but it adds a day or two to the timeline.

Domestic wire transfers are faster than ACH transfers partly because they use fewer intermediaries and because the Federal Reserve prioritizes them. An ACH transfer might pass through multiple processing centers before reaching the destination; a wire transfer usually moves more directly.

Frequently Asked Questions

Can I see which intermediary banks will handle my transfer before I send it?

Sometimes. Large banks can often tell you the routing path if you ask before sending the money. Smaller banks may not have this information readily available. You can also ask the receiving bank for their SWIFT code and the SWIFT codes of their correspondent banks, which gives you a clue about the likely routing path.

Why did my transfer arrive with less money than I sent?

Intermediary fees were deducted along the way. Each bank in the chain takes its fee from the amount passing through. If you sent $1,000 and three banks each took $15, you would receive $955. Ask your bank for an itemized list of which fees were charged by which banks.

How long does a transfer through intermediary banks usually take?

International transfers typically take three to five business days when intermediaries are involved. Domestic transfers usually take one to two business days. Weekends and holidays add extra time. Some transfers can take longer if the intermediary banks are in different time zones or if compliance checks are needed.

What is the difference between a correspondent bank and an intermediary bank?

A correspondent bank is any bank that another bank has a formal relationship with. An intermediary bank is a correspondent bank that is actively handling your specific transfer. All intermediaries are correspondents, but not all correspondents are intermediaries in your transaction.

Can I choose which intermediary banks handle my transfer?

Usually not. Your bank chooses the routing path based on its own correspondent relationships and the destination bank's requirements. Some banks offer options for international transfers — for example, choosing between a faster expensive route and a slower cheaper route — but you cannot typically specify individual intermediary banks.
